BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a novel and unique
multifunctional wireless medical stethoscope to be used by health
care professionals or the like for diagnosing patients and more
particularly to a unique and novel multifunctional wireless medical
stethoscope that includes a small microchip that operates in a
globally available frequency band ensuring communication compatibility
worldwide to auscultate human/animal organs and structural sounds
for wireless transmission from the patient to an earpiece worn
by the user.
2. Description of the Prior Art
The most common stethoscope primarily in use today by almost
all health care professionals is the manual stethoscope. The manual
stethoscope has had no significant design changes since the late
1800's. The manual stethoscope consists of a listening piece with
a diaphragm with sound being transmitted to the practitioners
ears via a "Y-tubing". However, due to this connecting
tube, the practitioner is very limited in his proximity to the
patient, innately causing the physical sounds transmitted to be
less than ideal.
In addition to the manual stethoscope, electronic stethoscopes
have been developed which use electronic wires to transmit sound
detected at the listening diaphragm to another device that reconverts
the transmission to sound. This technology has not substantially
changed for over 40 years.
It is evidenced in the prior art that numerous attempts have
been made to address the problems associated with the manual and
electronic stethoscopes. For example, U.S. Pat. No. 4,723,555
issued to Shue discloses a type of radio/wire stethoscopic apparatus
designed for multiple ausculatation and historical recording of
a patient. The circular diaphragm and Y-piece provide an overall
structure of the device, which is similar to the manual stethoscope
in use today. In addition, sound is received via the circular
diaphragm is converted to electrical signals and transmitted through
a radio/recorder set and an interface of audio wave control device
that is electrically coupled to the unit for enabling the wearer
to hear the received sound. Thus, providing for a stethoscope
that still provides a restricted amount of distance between him
and the patient, inherently providing a unit, unlike the present
invention, that does not reflect the most advanced technology
available today.
Yet another example is seen in U.S. Pat. No. 4,248,241 issued
to Tacchi wherein disclosed is patient monitoring apparatus which
employs transmitter and receiver units. The practitioner is still
physically connected to the patient with this device unlike the
present invention which is totally wireless.
U.S. Pat. No. 4,777,961 issued to Saltzman relates to a soley
patient mounted and supported constant monitoring suction stethoscopic
and radio transmitter system and remote radio receiver and speaker.
This device features a box-like structure which is clipped on
to the practitioners shirt thereby acting as a loud speaker, broadcasting
the precordial sounds out publicly.
In addition, U.S. Pat. No. 3,160,708 issued to Andries et al
relates to an electronic stethoscope adapted for diagnostic uses
and effective to reproduce heart sounds substantially approximating
the conventional acoustical stethoscope. This device has no wireless
components and unlike the present invention features dated technology.
As observed, none of the previous inventions as described above
have been utilized by the medical community. Thus, it is seen
that these previous efforts do not provide the benefits intended
with the present invention or method, such as providing a wireless
stereoscopic apparatus that ultimately delivers exceptional quality
and telecommunication capability. The present invention provides
a medical/educational stereoscopic device which features practicality
and uniqueness, by enabling wireless communication between the
patient and health care professional when diagnosing occurs, and
consequently provides an apparatus that would be quickly adopted
and used successfully by the medical community. Additionally,
prior techniques do not suggest the present inventive combination
of component elements as disclosed and claimed herein.
Accordingly, it is seen that there is a need for a wireless medical
stethoscope designed and configured to offer the most advanced
technology available today to the medical community. This medical
device is compact, easy to use, and has the advantage of allowing
freedom of movement and distance between the practitioners and
their patient. There is no connecting tube to limit the practitioners
proximity to the patient or to reduce the sound perception. Additionally,
the wireless medical stethoscope can be used by health care professionals
of all types.
Thus, as will be seen, the present invention achieves its intended
purposes, objectives and advantages over the prior art device
by accomplishing the needs and objectives as identified herein,
through a new, useful and unobvious combination of component elements,
which is simple to use, with the utilization of a minimum number
of functioning parts, at a reasonable cost to manufacture, assemble,
test and by employing only readily available materials.
SUMMARY OF THE INVENTION
The present invention is a novel and unique wireless medical
stethoscope that will advance the state of the art of medicine
by providing a higher level of patient care. This novel and unique
wireless stethoscope device is designed to be compact in size
and requiring a minimal amount of components so as to adequately
and successfully operate and manipulate the present invention.
To enable a wireless stethoscope, the present invention comprises
an auscultation piece, an earpiece, and a holding case for allowing
easy storage and transporting capabilities of the auscultating
piece and earpiece when not in use. Each component, including
the ausultation piece, earpiece, and carrying case are separate
structural entities.
Constructionally, the auscultation piece comprises a pyramidal
shape have an upper end and a lower end. The upper end is smaller
in size than the lower end, thus providing for the pyramidal shape.
Located on the side wall of the auscultation piece is a plurality
of indentations or grooves. These grooves form the typical finger
positioning of the examining physician or practitioner and thus
provide for an apparatus that is easy and efficient to use.
Located on the lower end of the auscultation piece is a sound
receptor panel or diaphragm for enabling auscultation of the patient.
Embedded within the auscultation piece is a conventional radio
frequency chip designed and configured for wireless transmission.
Preferably, this microchip will operate in a globally available
frequency band with a link manager ensuring communication compatibility
worldwide, thus increasing the usability and functionality of
the stethoscope apparatus of the present invention.
Activation can occur manually by depressing a button located
exteriorly on the auscultation piece, or optionally can be voice
activated. When not in use the auscultation piece can be coupled
to the earpiece for storage. This will provide for the earpiece
to be removably secured to the auscultation piece consequently
providing for a compact unit, when not in use.
The earpiece structurally includes a frame having a first end,
a second end and a middle section sandwiched therebetween. The
first end, second end and middle section form a substantially
J-shape configuration. It is noted that this frame is fabricated
from a durable, yet flexible material, so as to allow for the
wearer to adjust the overall structure of the frame so as to enable
it to conform to their particular shape. Pivotally secured to
the second end is a hearing piece. This hearing piece is conventional
in design and thus, is configured to be inserted into the ear
of the user for allowing adequate and comfortable listening compabilities.
Embedded within the main frame is a link manager receiver device.
The link manager receiver is in communication with the auscultation
piece, so as to receive the sounds when the auscultation piece
is placed on the patient. Located on the mainframe and coupled
to the link manager receiver device is a sound adjustment unit.
This sound adjustment unit is a conventional mechanical device
that is utilized for adjusting the volume for the sounds received
via the link manager receiver.
For providing removable attachment capabilities, the auscultation
piece and earpiece can include corresponding locking means. This
will provide for the auscultation piece and earpiece to be removably
secured to each other and thus provides a device, when not in
use, to be stored as a singular entity. The locking means is conventional
and can be any locking means that will ensure quick and efficient
release and engagement of the earpiece to the auscultation piece.
The auscultation piece and the earpiece mate together to then
fit into a holder device. This holder device can further include
conventional attachment mechanism, such as the use of clips for
rendering attachment to the pants or jacket of the health care
professional.
This novel and unique wireless stethoscope device provides faster
throughput and better reliablity than present systems. Since the
sound is transmitted wirelessly, quality is not lost wherein with
conventional stethoscopes the sound waves must travel through
the Y-piece tubing to the listening ear. Any amount of traveling
will reduce the quality of sound being heard by the health care
professional.
Normally in the use of the manual stethoscope or the electronic
stethoscope the following problems may be encountered: i. The
mobility of the physician or practitioner is generally quite limited.
ii. The quality of the sound for diagnosis may be compromised.
iii. The state of the art of the technology is often lacking.
Thus, the present manual and electronic stethocopes often do not
offer the physician or practitioner the opportunity to achieve
a higher level of patient care and greater productivity by being
able to rapidly monitor and detect the onset of medical problems
while being totally free of any physical connection to the patient.
Using and operating the present invention is simple, easy, and
extremely efficient. The present invention will elevate the role
of the stethoscope in modern medicine. In addition, the novel
and unique wireless medical stethoscope will advance the technology
in the art of stethoscopes.
Accordingly, it is an object of the present invention to provide
for a wireless medical stethoscope device that will overcome the
deficiencies, shortcomings, and drawbacks of prior medical stethoscope
devices.
Another object of the instant invention is to provide a wireless
medical stethoscope which will not limit the mobility of the practitioner
or limit the use of his hands to the length of the stethoscope
tubing, but provides the ability to privately hear all the medical
sounds as in the original manual stethoscope.
Still another object of the present invention is to provide a
novel method of use of the wireless medical stethoscope such that
the novel device is completely portable and can be rapidly activated.
A further object of the present invention is to provide a wireless
medical stethoscope device which is light weight and simple in
design so as to provide for a medical device which can provide
for a more efficient and effective process for assessing, monitoring
and detecting the onset of medical problems. This medical device
will provide for an option for programmable versions for teaching
purposes, telemedicine conferencing as well as a loudspeaker means.
Yet another object of the present invention is to provide for
a novel and unique medical device which can provide improved continuous
assessing and monitoring of the patient, including, but not limed
to those undergoing surgical procedures, obstetrics delivery,
emergency medical trauma, or the like.
Another object of the present invention is to provide for a novel
and unique wireless medical stethoscope which can be used on both
human and animal patients.
Still a further object of the present invention, to be specifically
enumerated herein, is to provide a medical device in accordance
with the preceding objects and which will conform to conventional
forms of manufacture, be of simple design and easy to use so as
to provide a medical device that will be economically feasible,
long lasting and relatively trouble free in operation.
Although there have been many inventions related to stethoscope
medical devices, none of the prior art related to the present
invention has been designed to provide the most advanced technology
available today. The present invention meets the requirements
of simplified design, compact size, low initial cost, low operating
cost and ease of maintainability.
The foregoing has outlined some of the more pertinent objects
of the invention. These objects should be construed to be merely
illustrative of some of the more prominent features and application
of the intended invention. Many other beneficial results can be
obtained by applying the disclosed invention in a different manner
or modifying the invention within the scope of the disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As seen in the drawings, in particular to FIGS. 1-15 thereof,
the first embodiment of the present invention, a novel and unique
medical device for wireless medical stethoscopes, denoted by reference
numeral 10 (see assembled stored apparatus illustrated in FIG.
1 and disassembled in FIG. 2) will be described herein. Shown
is a wireless medical stethoscope device 10 (see FIG. 1 and FIG.
2), which comprises an earpiece apparatus 12 (see FIGS. 1-9),
an auscultation piece apparatus 14 (see FIGS. 1, 2 and 10-14),
and a holding device 16 (see FIGS. 1, 2 and 15). It is noted that
the embodiment illustrated in FIGS. 1-9 illustrates an earpiece
apparatus that is to be used on a right ear. The embodiment for
the left ear is not illustrated, but it is to be understood that
this left ear embodiment will be substantially the same shape,
size and configuration, with the exception of being a mirror image,
of the embodiments shown in the figures. Thus, this left ear configuration
will not be separately illustrated.
As seen in FIGS. 1-15, the ear piece apparatus 12 is removably
lockable to the auscultation piece apparatus 14 to provide for
a singular unit when not in use on a patient and when in the locked
storable position. This will provide for the ear piece and auscultation
piece to form a lockable unit that is removably secured to the
holding device 16. The holding device 16 will maintain the ear
piece and auscultation piece in a storable and protected environment.
The object of the present invention is to provide for a medical
stethoscope that is not only wireless, but one that is compact
in size and which will produce a higher quality of sound than
conventional stethoscope, also known as a manual stethoscope.
In order to achieve this wireless system, the present invention
includes the removable components including the ear piece apparatus
12 and auscultation piece apparatus 14.
In use, the health care professional will remove the unit (earpiece
locked to the auscultation piece) from the holding device. In
the preferred embodiment, the unit is removed from the holder
and, in one swift motion, the practitioner's will secure the earpiece
to his ear, wherein the listening portion of the earpiece is placed
firmly to the ear. Once secured thereto, the auscultation piece
is removed (disengaged from the earpiece) therefrom (see FIG.
2). The auscultation piece is placed on the patient's body in
the area to be auscultated. The present invention can then be
utilized efficiently and accurately.
As seen in FIGS. 1 through 9, the earpiece comprises a mainframe
18 having a first end or post auricular 20, a second end or pre-auricular
22 and a middle portion (illustrated, but not labeled) therebetween.
This frame forms a substantial J-shape configuration for rendering
a frame that will accept and rest comfortably on the ear. This
middle portion of the frame, in the preferred embodiment, is fabricated
from a durable, yet resilient and pliable material, such as polymer,
polymer-coated metal, or the like. This will enable the earpiece
to be adjustable by allowing the user to bend and adjust the pliable
frame to conform to the size and shape of the wearer's ear. Thus
provide for a more comfortable and accurate fit.
As seen in FIGS. 3-9, the first end 20 includes an opening or
aperture (illustrated, but not labeled). This opening or aperture
is optional, and is provided if the user wishes to doubly secure
the earpiece. In one embodiment, a small rope, string or the like,
is secured to this aperture, and its opposites ends are joined
securely for innately forming a closed loop configuration. In
this design, when the earpiece is secured to the ear, the user
can wrap the closed loop around their ear and around one of the
posts. This will doubly secure the earpiece to the user. The circumference
of the loop should be of an adequate size so as to enable a comfortable
and secured fit thereon. Thus, this circumference should be approximately,
but not limited to, 2.5 to 4.5 inches. Alternatively, the material
used for the rope, string or the like can possess resilient properties.
This arrangement of doubly securing the earpiece to the wearer
is ideally suited for those who work in a busy environment such
as a trauma physician running a code blue or the like.
In an alternative configuration, the aperture can accept a longer
rope, string, chain or the like, wherein, its opposite ends are
secured in order to form a larger closed loop. This arrangement
will allow the earpiece to hang from a string, chain, clip or
the like. The closed loop can be located around the user's neck,
clipped to their nametag or the like.
Located at the opposite end or second end 22 is the hearing portion
24. This hearing portion 24 is substantially conventional and
will be placed within the ear of the wearer or user and thus includes
a speaker located therein. To add to the comfort of the earpiece,
this portion can be altered via an adjusting device. As shown
in FIG. 7, the adjusting device preferably is a ball and socket
configuration. This will provide for the frame to include a groove
26, which will act as a socket. The hearing portion 24 will include
a ball segment 28, thus rendering for the ball segment to rest
within the socket 26 of the frame and allow it to rotate freely
therein. This will provide for a hearing portion that is adjustable,
and one that will adjust naturally to the user. Optionally, a
screw or the like can be used for locking and securing the ball
segment within the socket.
The adjusting device can be altered to provide for the hearing
piece 24 to be pivotally secured to the second end 22 of the main
frame 18. This alternative configuration is shown in FIG. 8. As
seen, the pivotal attachment is conventional, and thus provides
for the hearing piece 24 to pivot freely about pivot rod 30. This
rod can have a threaded end, so that this hearing piece 24 can
be locked by allowing a nut or the like to rotate about the threaded
end and lock the hearing piece 24 in a fixed and secured position.
Alternatively, this hearing piece 24 can be secured to the second
end 22 of the main frame 18 by way of a hollow flexible shaft.
In this configuration, the shaft can be bent to the desired angular
placement for providing a comfortable and accurate fit. In this
configuration, the locking mechanism for locking the hearing piece
in a fixed position is eliminated.
Extending upwardly from the curved area or center area of the
frame of the earpiece 12 is the securing unit 32. This securing
unit 32 is used to secure the earpiece 12 to the auscultation
piece 14 when the device is not in use. This securing unit 32
will be discussed in further detail when discussing the receiving
unit of the auscultation piece 14 for receiving the securing unit.
Externally located within the frame 18 of the earpiece 12 is
a link manager receiver device 34 (illustrated in outline in FIGS.
5 and 6). This link manager receiver device 34 works in combination
with the auscultation piece for enabling the sound auscultated
from the portion of the body to be received and heard by the earpiece
12.
The sound that is transmitted can be controlled via a conventional
volume control knob 36 as seen in FIGS. 4-6. In this arrangement,
the user can amplify or de-amplify the sounds so as to suit their
particular needs. This feature not only enhances the final product,
but enables those with impaired hearing and those with presbyascusis
to still practice in the medical profession, due to the ability
of increasing the volume of the wireless stethoscope of the present
invention and allowing them to adequately hear the desired sounds.
The auscultation piece 14, illustrated in FIGS. 1, 2, and 9 through
13 is designed and configured to be handled easily, efficiently
and accurately. In order to do so, the auscultation piece 14 includes
a unique design and configuration. As seen, the auscultation piece
includes a lower portion or inferior 38 and an upper portion or
superior 40. The lower portion is larger is size than the upper
portion so as to provide for an overall pyramidal shape. As further
seen, located along the side wall of the auscultation piece 14
are four indentations or recesses 42. These indentations are designed
and configured to receive the tips of the first digit (thumb),
second digit (index finger), third digit (middle finger), and
the tip of the fourth digit (ring finger). The user may wish not
to use this fourth indentation. The recesses provide efficient
gripping capabilities for enabling adequate manipulation of the
auscultation piece. Optionally, the lower portion can further
include a flange (see FIG. 10), illustrated but not labeled, that
will be used in combination with the carrying case. This will
allow for the auscultation piece to slide within the carrying
case via the use of the flange.
Embedded within the auscultation piece is a conventional radio
frequency chip 44 (illustrated in outline). This chip is conventional
and is structured so as to operate in a globally available frequency
band ensuring communication compatibility worldwide to ausculatate
humans/animals, organs, structural sounds, or the like, for wireless
transmission. This microchip will allow for the user to operate
the unit wireless, and thus enable the transmitter to transmit
the signals successfully and innately allow for adequate transmission
from the auscultation piece to the earpiece. The most recent advanced
chip technologically available, which has been used to achieve
favorable results, is ideal for use in wireless communication networks, although
simplified chips utilizing any radio frequency range can also
be used in the medical device of the present invention.
Located in the auscultation piece, as seen FIG. 12, is a diaphragm
46. This diaphragm is designed and configured to procure the sounds
for transmission from the auscultation piece to the earpiece.
This diaphragm, also known as the auscultation panel includes
a condenser microphone and is of a conventional design.
The top surface or dorsal of the auscultation piece, as seen
in FIGS. 1, 2, and 13 and as illustrated in the side view (FIGS.
9 and 12) includes at least one activation button or switch 48.
This switch 48 is used to activate and/or deactivate the auscultation
piece. When in use, this switch is depressed and when desired
to deactivate the auscultation piece, this same button is pressed
for terminating power transmission. Optionally, and in the preferred
embodiment, this switch can be used for releasing or engaging
the earpiece to the auscultation piece.
Optionally, a second switch 50 can be utilized in combination
with the first switch. In this configuration, the first switch
can be used to activate the unit, while the second switch can
be used to deactivate the unit. Alternatively, both switches can
be depressed simultaneously for allowing the unit to be activated
or deactivated. In an alternative embodiment, a voice-activated
unit can be used for activating the unit. Alternatively, and as
is preferred, the switch can be coupled to a timer, which will
initiate the transmission of sound after a pre-determined amount
of time and if sound is not detected will automatically deactivate
the unit. This arrangement will consequently provide a unit that
is not only accurate in transmission of signals, but also one
that conserves energy when not in use.
Once the system is activated, the user places the auscultation
piece on the patient. When sound, such as the pulse of the patient,
is received, an indicator 52 will activate. In the preferred embodiment,
the indicator is a light source, such as a conventional LED, that
flashes with each sound heard.
To power the unit, conventional means are utilized. As seen in
FIG. 11, batteries are stored and housed within the battery housing
54 and are utilized to power the auscultation piece.
Information, such as sound, is transmitted instantaneously to
the earpiece via the main unit or chip 44. Optionally, the received
data can be transmitted to a secondary source or any desired sources
by coupling the unit to a computer or the like. To enable coupling,
a data port 56 is utilized. Dependent upon the chip, which is
used, the auscultation piece can include the capability of storing
data. In this arrangement, the stored data can be downloaded via
the hard wired port or data port 56. Downloading data is ideal
for quickly receiving a second opinion, for medical record keeping,
teaching and can enable a health care profession to transmit sound
across for use in Tele medicine. The use of such a configuration
will inherently increase the usability and capability of the medical
apparatus of the present invention.
As seen in FIGS. 1, 2, 11 and 13, grooves 58 are located in the
sidewall of the auscultation piece. These grooves are a receiving
device and thus will receive the securing unit of the earpiece.
As seen in FIGS. 1, 2, 3, and 6, the securing unit comprises at
least one post or shaft 60. This post is received within at least
one groove so as to rest therein and enable accurate placement
of the auscultation piece and earpiece to the carrier. This post
also acts as a stop, and thus when the auscultation piece is located
within the holding case, the user can place the earpiece therein.
When sliding the earpiece therein, the grooves will receive the
post(s) and once received the post will prevent the earpiece from
sliding further therein and thus prevent damage to the ear piece
and/or auscultation piece.
As seen in FIG. 6, the top area of the posts can include an enlarged
portion (illustrated, but not labeled). This enlarged portion
will prevent the earpiece for dislodging for the auscultation
piece.
Optionally, included can be a lockable device for locking the
post to the auscultation piece. In one embodiment, the lockable
device can be nuts and the posts can be threaded. Thus the user
will rotate the nuts until it is secured within the unit. Optionally,
conventional pivotal pins 62 can be used. As seen in FIG. 11,
in this design, the user depresses a button 50 for allowing the
pins to open and once the posts are located therein, the button
is released, and the posts lock the pins within the grooves. Still
a further lockable device would be to allow for the pins 62 to
be spring loaded, so that the user merely pushes the posts on
the pins to enable the post to fit into the recess portion. Once
therein, the pins will pivot back to its original position. It
is noted that the lockable device is designed to quickly lock
the earpiece to the auscultation piece and thus will allow for
any conventional unit that renders such a configuration.
Optionally, in the preferred embodiment, the earpiece can include
shafts that will catch a hook. In this design, as seen in FIGS.
1, 2, and 13 extending outwardly from the grooves 58 of the auscultation
piece 14 are spring loaded hooks 68 that are coupled to a release
button 64. Optionally, these hooks can be coupled to one or both
of the activation buttons, 48 and/or 50. In this configuration,
if the user depresses the release button the hooks will raise
inward or outward. This will provide for a clearance to exist
between the shafts and the hook and permit the earpiece to be
removed from or travel towards the auscultation piece. Releasing
the button will provide for the hooks to return to its original
position.
The carrying case 16, as seen in FIGS. 1, 2 and 14 is designed
to maintain the earpiece and auscultation piece when not in use
and includes a top area 70 and a rear or back area 72. The top
area includes upward and inward walls 74 that inherently form
channels. These channels will slideably receive the outer ends
of the auscultation piece and earpiece. The rear area includes
a conventional attaching unit 76, such as a clip or the like,
for attaching the device to the user, when not in use. This clip
can be spring loaded, as illustrated.
Generally, when the carrying case is used, the unit (earpiece
and auscultation piece) are secured therein providing the case
to be in an upward and/or slightly forward position. This upward
and slightly forward position will prevent the unit from disengaging
from the carrying case.
To ensure placement of the unit therein, a lock, not illustrated,
can be used. This lock can be a spring-loaded shaft. In operation,
the shaft is depressed to provide for the unit to enter the carrying
case or to prevent the unit from escaping and dislodging from
the carrying case. This will protect the unit and prevent damage
to occur therewith.
The electrical components used for successful transmission of
sound are illustrated in FIG. 15. As seen in this block diagram,
the auscultation piece 14 is coupled to a power source 80 via
a switch 48. It is noted that this switch can be coupled to two
separate activation buttons. In this design, one switch will activate
the unit (turn it on by providing a close circuit) and the second
button will deactivate the unit (turn it off by providing an open
circuit) or in a separate configuration, both buttons must be
depressed simultaneously in order for activation to occur.
A microphone 82 is used to convert sound into electrical signals.
Once sound is detected, the signals travel from the microphone
to a relay 84. This relay will activate switch 86, which is coupled
to an indicator 52. Thus, upon the detection of sound, the relay
will cause the switch to close and allow current to travel to
the indicator. The current will cause the indicator to activate
and thus allow for a visual means when there is a presence of
sound.
From the microphone 82 the signals are amplified via the amplifier
88, and used to modulate a carrier wave that has been generated
by a transmitter 90. This modulated carrier is also amplified
and then applied to a converter 92 for enabling the electrical
signals to be converted to electromagnetic waves for transmission.
These electromagnetic waves are sent to the earpiece 12 and are
intercepted and converted back to electrical signals via a decoder
94. These electrical signals are feed to a receiver 96 and separated
from the carrier wave. Once separated, then are fed to a speaker
98, where they are converted into sound. The sound can be adjusted
via conventional volume control means 36. The earpiece is powered
via a power source 100.
It is noted that the decoder 94, receiver 96, and speaker 98
form the link manager receiver device 34. To enhance the final
product, a timer 102 can be used to delay the time for power to
be sent to the microphone.
To utilize the present invention, the practitioner, places the
tips of his first three or four fingers on the grooves of the
auscultation piece. Moving his arm upward, the practitioner removes
the auscultation piece, which is still attached to the earpiece.
Using the auscultation piece as a handle, the practitioner places
the earpiece on his ear, with the soft hook catching the Pinna
of the ear and setting the earpiece into position.
At this point, the release button is depressed, releasing the
auscultation piece from the earpiece and activating the microphone
for adequate operation. The lower portion of the auscultation
piece is brought into place over the area to be listened. Appropriate
transmission of sound occurs wireless, thus providing for sound
to travel from the auscultation piece to the hearing portion of
the earpiece.
After examination is completed, the activation button is pressed
for termination of transmission. The release button is depressed
to allow for the earpiece to mate with the auscultation piece.
The mated pieces are slideably secured to the holding case for
storage.
To enhance the final product, a microprocessor can be coupled
with the link manager. Generally, dependent upon the chip (semi-conductor)
that is used, the microprocessor may be included therein. If not,
one can be coupled to the link manager. The use of a microprocessor
will enable for the heard sound (data) to be stored therein. This
data can then be transmitted to the desired location via the data
port 56. Dependent on the microprocessor that is used, other data
can be programmed into the present invention via the data port
and stored within the microprocessor. It is noted that this microprocessor
can be programmed to perform any desired task as deemed necessary
by the user and innately provide for a medical apparatus with
a plurality of options and usability.
While the invention has been particularly shown and described
be understood by those skilled in the art that various changes
in form and detail may be made without departing from with reference
to an embodiment thereof, it will the spirit and scope of the
invention.
