Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a head-mounted stethoscope for monitoring heart diseases. Background Art

[0002] By acquiring the sounds of human internal organ activity outside the body, medical staff can preliminarily determine the cause of the disease. Therefore, stethoscopes are often used in clinical work. However, most traditional stethoscopes are in-ear type. When performing physical examinations on a large number of people, or monitoring cardiac function in the cardiac rehabilitation pathway after pacemaker implantation, long-term auscultation work will seriously damage the doctor's external auditory canal mucosa. In view of this, a head-mounted stethoscope for heart disease monitoring is proposed. Summary of the Invention

[0003] The purpose of the present invention is to provide a head-mounted stethoscope for monitoring heart disease, which can effectively reduce the damage to the external auditory canal mucosa caused by long-term auscultation work, and combine with visualization technology to further improve the efficiency and effect of auscultation.

[0004] The technical solutions adopted by the present invention are as follows:

[0005] A head-mounted stethoscope for monitoring heart disease comprises a U-shaped frame having a U-shaped groove formed therein. The U-shaped groove is engaged with the upper ends of two extension plates, and the bottom ends of the two extension plates are fixedly connected to the outer surfaces of two earmuffs respectively.

[0006] The inner sides of the two earmuffs are fixedly provided with sound insulation cotton, and the inner sides of the two sound insulation cottons are respectively fixedly connected to the ends of the two mounting plates. The opposite surfaces of the two earmuffs are respectively overlapped with the opposite surfaces of the two cover plates, and the opposite surfaces of the two cover plates are respectively fixedly connected to the opposite surfaces of the two sponge pads 2. The inner side of the U-shaped frame is fixedly connected to the sponge pad 1.

[0007] Furthermore, a group of positioning holes are opened at both ends of the inner side surface of the U-shaped groove, and the two groups of positioning holes are respectively plugged into the opposite ends of the two positioning rods, and the opposite ends of the two positioning rods are respectively fixedly connected to the opposite sides of the two extension plates.

[0008] Furthermore, a plurality of sound-transmitting grooves are formed around each of the cover plates, and a mesh plate is fixedly arranged in each of the sound-transmitting grooves.

[0009] Furthermore, the opposite sides of the two cover plates are fixedly connected to the opposite ends of the two groups of sliders, and the opposite ends of the two groups of sliders are slidably connected to the two annular grooves. The outer side surface of the end of each slider is fixedly provided with a silicone air cushion, and the silicone air cushion overlaps the annular groove. When connecting the cover plate to the earmuff, the cover plate can be taken so that the slider corresponds to the connecting groove, and the slider is inserted into the annular groove through the connecting groove. When the front end of the slider also enters the inside of the annular groove, the slider squeezes the silicone air cushion to compress the silicone air cushion, and then the user can twist the cover plate to rotate the cover plate forty-five degrees to make the slider deviate from the connecting groove. At this time, the silicone airbag is in a compressed state, so that the elastic force generated when the silicone airbag is compressed is used to apply an extrusion force to the slider, thereby increasing the friction between the slider and the annular groove, thereby effectively improving the installation stability of the cover plate.

[0010] Furthermore, the two annular grooves are respectively opened on the inner sides of the two fixing rings, and the outer sides of the two fixing rings are respectively fixedly connected to the inner sides of the two earmuffs.

[0011] Furthermore, a plurality of connecting grooves are provided at the opposite ends of the two annular slide grooves, and the opposite ends of the connecting grooves on the front and rear sides are respectively connected with the opposite surfaces of the two fixing rings. When using this device, the user can press the cover plate backward so that the cover plate squeezes the silicone airbag, and then twist the cover plate forty-five degrees so that the cover plate rotates to correspond to the connecting groove. At this time, the user can pull the cover plate forward to disengage the slider from the annular slide groove, thereby removing the cover plate to clean the mesh plate, and the user can also disassemble and replace the fixing seat and mounting ring to maintain the audio.

[0012] Furthermore, the opposite sides of the two mounting plates are fixedly connected to the opposite ends of the two batteries, the input ends of the two batteries are electrically connected to the two charging sockets, the two charging sockets are respectively arranged at the bottom ends of the two earmuffs, the two batteries are electrically connected to the control host, the bottom surface of the control host is fixedly connected to the upper surface of the fixed frame, and the control host is also electrically connected to the radio head through a wire.

[0013] Furthermore, the opposite surfaces of the two mounting plates are overlapped with the opposite surfaces of the two fixing seats respectively, and the two fixing seats are connected to the two mounting plates respectively through screw holes and bolts, and the opposite surfaces of the two fixing seats are fixedly connected to the opposite ends of the two support frames respectively, and the opposite ends of the two support frames are fixedly connected to the opposite surfaces of the two mounting rings respectively, and the opposite surfaces of the two mounting rings are surrounded by a plurality of fixing grooves 2, and a speaker is fixedly installed in each of the fixing grooves 2, and the plurality of speakers are electrically connected to the control host.

[0014] Furthermore, the bottom surface of the fixed frame is fixedly connected to the upper end of the outer surface of the U-shaped frame, the fixed frame is sleeved with the left end of the fixed plate, and the right end of the fixed plate is fixedly connected to the upper end of the holographic glasses. The left ends of the front and rear side surfaces of the fixed plate are each provided with a fixing groove 1, and the opposite ends of the two fixing grooves 1 are respectively fixedly connected to the opposite ends of two groups of telescopic rods and two groups of springs. The holographic glasses are electrically connected to the control host. By setting the holographic glasses to be connected to the U-shaped frame, the user can selectively install the holographic glasses on the U-shaped frame and connect the holographic glasses to the control host, so as to use the control host to convert the heart sound data into a beating image to achieve visualization, thereby effectively improving the auscultation effect and efficiency.

[0015] Furthermore, the two groups of springs are respectively sleeved on the outsides of the two groups of telescopic rods, and the opposite ends of the two groups of telescopic rods and the two groups of springs are respectively fixedly connected to the opposite surfaces of the two pressing plates, and the two pressing plates are respectively sleeved in the two fixing grooves. The opposite surfaces of the two pressing plates are each provided with a group of fixing holes, and the two groups of fixing holes are respectively sleeved with the opposite ends of the two fixing rods. The opposite ends of the two fixing rods are respectively fixedly connected to the front and rear inner sides of the fixing frame. When using the holographic glasses, the user can press the pressing plates on both sides to move into the fixing groove, so that the two pressing plates respectively squeeze the front and rear groups of telescopic rods and springs. Then the user can insert the left end of the fixing plate into the fixing frame and release the two pressing plates when adjusting the holographic glasses to the appropriate position. At this time, the elastic force of the two groups of springs is used to push the two pressing plates away from each other, so that the fixing holes at the corresponding positions on the two pressing plates are plugged into the fixing rods to fix the positions of the fixing plates and the holographic glasses. Then the holographic glasses are connected to the control host using a data cable, so that the control host converts the wearer's heart sound data into images and transmits them to the holographic glasses for display.

[0016] The technical effects achieved by the present invention are:

[0017] The present invention provides a mounting ring and a speaker inside the earmuff. When in use, the earmuff can be worn on the ear, and the sound receiving head is placed close to the patient's chest cavity. The patient's heart sounds are received by the sound receiving head, and the heart sound data is transmitted to the control host by a wire. The control host then plays the heart sounds through the speaker, effectively reducing the damage to the external auditory canal mucosa caused by long-term auscultation. At the same time, by connecting the holographic glasses to the U-shaped frame, the user can selectively install the holographic glasses on the U-shaped frame and connect the holographic glasses to the control host, so that the control host can convert the heart sound data into a beating image to achieve visualization, thereby effectively improving the auscultation effect and efficiency.

[0018] The present invention connects the extension plate with the U-shaped frame by providing a positioning rod and a positioning hole. When wearing the device, the user can pull the extension plate to slide in the U-shaped groove, so that the positioning rod is engaged with the positioning holes at different positions, thereby using the height of the sliding earmuff of the extension plate to adjust, so that the device can be suitable for wearers of different body shapes. At the same time, the fixing plate is sleeved with the fixing frame, and the fixing plate and the fixing frame are further connected by providing a telescopic rod, a spring, a pressing plate, a fixing hole and a fixing rod, thereby facilitating the user to disassemble and assemble the fixing plate and the holographic glasses. When using the holographic glasses to view the heart sound image, the wearer can pull the fixing plate to slide along the fixing frame to adjust the position of the holographic glasses according to his or her own needs, thereby effectively improving the applicability of the device.

[0030] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0031] like Figure 1-9 As shown, a head-mounted stethoscope for monitoring heart disease includes a U-shaped frame 1, the U-shaped frame 1 having a U-shaped groove 17 formed therein. The U-shaped groove 17 is simultaneously engaged with the upper ends of two extension plates 3, and the bottom ends of the two extension plates 3 are respectively fixedly connected to the outer surfaces of two earmuffs 4;

[0032] Sound insulation cotton 23 is fixedly provided on the inner sides of the two earmuffs 4. The inner sides of the two sound insulation cottons 23 are fixedly connected to the ends of the two mounting plates 25 respectively. The opposite surfaces of the two earmuffs 4 are overlapped with the opposite surfaces of the two cover plates 19 respectively. The opposite surfaces of the two cover plates 19 are fixedly connected to the opposite surfaces of the two sponge pads 20 respectively. The inner side of the U-shaped frame 1 is fixedly connected to the sponge pad 1 2.

[0033] A set of positioning holes 18 are formed at both the front and rear ends of the inner side of the U-shaped groove 17. The two sets of positioning holes 18 are respectively plugged into the opposite ends of the two positioning rods 37. The opposite ends of the two positioning rods 37 are respectively fixedly connected to the opposite sides of the two extension plates 3.

[0034] Each cover plate 19 is surrounded by a plurality of sound-transmitting grooves 21, and a mesh plate 22 is fixedly installed in each sound-transmitting groove 21. By arranging the mesh plate 22 in the sound-transmitting groove 21, the mesh plate 22 is used to seal and protect the sound-transmitting groove 21, thereby preventing external debris from entering the earmuff 4 through the sound-transmitting groove 21 and causing blockage of the speaker 27.

[0035] The opposite sides of the two cover plates 19 are fixedly connected to the opposite ends of the two groups of sliders 32, and the opposite ends of the two groups of sliders 32 are slidably connected to the two annular grooves 36. The outer side surface of the end of each slider 32 is fixedly provided with a silicone air cushion 33, and the silicone air cushion 33 overlaps the annular groove 36. When the cover plate 19 is connected to the earmuff 4, the cover plate 19 can be taken so that the slider 32 corresponds to the connecting groove 35, and the slider 32 is inserted into the annular groove 36 through the connecting groove 35. When the front end of the slider 32 also enters the annular groove 36, the slider 32 squeezes the silicone air cushion 33 to compress the silicone air cushion 33. Then the user can twist the cover plate 19 so that the cover plate 19 rotates forty-five degrees so that the slider 32 deviates from the connecting groove 35. At this time, the silicone air bag is in a compressed state, so that the elastic force generated by the compression of the silicone air bag exerts an extrusion force on the slider 32, thereby increasing the friction between the slider 32 and the annular groove 36, effectively improving the installation stability of the cover plate 19.

[0036] Two annular slots 36 are respectively provided on the inner sides of the two fixing rings 34 , and the outer sides of the two fixing rings 34 are respectively fixedly connected to the inner sides of the two earmuffs 4 .

[0037] A plurality of connecting grooves 35 are provided at the opposite ends of the two annular slide grooves 36, and the opposite ends of the connecting grooves 35 on the front and rear sides are respectively connected with the opposite surfaces of the two fixing rings 34. When using this device, the user can press the cover 19 backward so that the cover 19 squeezes the silicone airbag, and then twist the cover 19 forty-five degrees so that the cover 19 rotates to correspond to the connecting grooves 35. At this time, the user can pull the cover 19 forward so that the slider 32 disengages from the annular slide groove 36, thereby removing the cover 19 to clean the mesh plate 22, and the user can also disassemble and replace the fixing seat 30 and the mounting ring 28 and maintain the speaker 27.

[0038] The opposite sides of the two mounting plates 25 are fixedly connected to the opposite ends of the two batteries 24, and the input ends of the two batteries 24 are electrically connected to the two charging sockets, which are respectively arranged at the bottom ends of the two earmuffs 4. The two batteries 24 are both electrically connected to the control host 9, and the bottom surface of the control host 9 is fixedly connected to the upper surface of the fixed frame 10. The control host 9 is also electrically connected to the radio head 6 through the wire 5.

[0039] The opposite surfaces of the two mounting plates 25 are overlapped with the opposite surfaces of the two fixing seats 30 respectively, and the two fixing seats 30 are connected to the two mounting plates 25 respectively through screw holes and bolts 29. The opposite surfaces of the two fixing seats 30 are fixedly connected to the opposite ends of the two support frames 31 respectively, and the opposite ends of the two support frames 31 are fixedly connected to the opposite surfaces of the two mounting rings 28 respectively. The opposite surfaces of the two mounting rings 28 are surrounded by a plurality of fixing grooves 26, and a speaker 27 is fixedly arranged in each fixing groove 26. The multiple speakers 27 are electrically connected to the control host 9. By arranging the mounting ring 28 and the speaker 27 in the earmuff 4, the earmuff 4 can be worn on the ear when in use, and the microphone 6 is placed against the patient's chest cavity. The patient's heart sounds are received by the microphone 6, and the heart sound data is transmitted to the control host 9 by using the wire 5. The control host 9 then plays the heart sounds through the speaker 27, effectively reducing the damage to the external auditory canal mucosa caused by long-term auscultation.

[0040] The bottom surface of the fixed frame 10 is fixedly connected to the upper end of the outer surface of the U-shaped frame 1, the fixed frame 10 is socketed with the left end of the fixed plate 8, and the right end of the fixed plate 8 is fixedly connected to the upper end of the holographic glasses 7. The left ends of the front and rear sides of the fixed plate 8 are each provided with a fixing groove 12, and the opposite ends of the two fixing grooves 12 are respectively fixedly connected to the opposite ends of two groups of telescopic rods 15 and two groups of springs 16. The holographic glasses 7 are electrically connected to the control host 9. By setting the holographic glasses 7 to be connected to the U-shaped frame 1, the user can selectively install the holographic glasses 7 on the U-shaped frame 1 and connect the holographic glasses 7 to the control host 9, so as to use the control host 9 to convert the heart sound data into a beating image to achieve visualization, thereby effectively improving the auscultation effect and efficiency.

[0041] The two groups of springs 16 are respectively sleeved on the outside of the two groups of telescopic rods 15, and the opposite ends of the two groups of telescopic rods 15 and the two groups of springs 16 are respectively fixedly connected to the opposite surfaces of the two pressing plates 11. The two pressing plates 11 are respectively sleeved in the two fixing grooves 12. A group of fixing holes 14 are opened on the opposite sides of the two pressing plates 11. The two groups of fixing holes 14 are respectively sleeved with the opposite ends of the two fixing rods 13. The opposite ends of the two fixing rods 13 are respectively fixedly connected to the front and rear inner sides of the fixing frame 10. When using the holographic glasses 7, the user can press the pressing plates 11 on both sides to move them into the fixing groove 12, so that the two pressing plates 11 squeeze the front and rear groups of telescopic rods 15 and springs 16 respectively. Then the user can insert the left end of the fixing plate 8 into the fixing frame 10 and release the two pressing plates when the holographic glasses 7 are adjusted to the appropriate position. 11. At this time, the two sets of springs 16 are used to push the two pressing plates 11 away from each other, so that the fixing holes 14 at the corresponding positions on the two pressing plates 11 are plugged into the fixing rods 13 to fix the positions of the fixing plate 8 and the holographic glasses 7. Then, the holographic glasses 7 are connected to the control host 9 by a data cable, so that the control host 9 converts the wearer's heart sound data into images and transmits them to the holographic glasses 7 for display. At the same time, the fixing plate 8 is further connected to the fixing frame 10 by setting the telescopic rod 15, spring 16, pressing plate 11, fixing holes 14 and fixing rod 13, so that the user can disassemble and assemble the fixing plate 8 and the holographic glasses 7. When using the holographic glasses 7 to view the heart sound images, the wearer can pull the fixing plate 8 to slide along the fixing frame 10 to adjust the position of the holographic glasses 7 according to his or her own needs, thereby effectively improving the applicability of the device.

[0042] The working principle of the present invention is as follows: when using the device, the user can first adjust the height of the earmuff 4 according to his or her own needs. At this time, the user can pull the extension plate 3 up and down to slide in the annular slide groove 36. When the extension plate 3 slides, the positioning rod 37 is elastically deformed and disengaged from the positioning hole 18. When the next positioning hole 18 slides to correspond to the positioning rod 37, the positioning rod 37 is plugged into the positioning hole 18 at the corresponding position. When the earmuff 4 is adjusted to a suitable position, the extension plate 3 is stopped from being pulled, and the positioning rod 37 is plugged into the positioning hole 18 at the corresponding position. Then, the user can wear the U-shaped frame 1 on the head so that the earmuff 4 fits the ear, and the sound receiving head 6 is placed against the patient's chest cavity. The patient's heart sounds are received by the sound receiving head 6, and the heart sound data is transmitted to the control host 9 by the wire 5. Then, the control host 9 plays the heart sounds through the speaker 27.

[0043] When using the device, the user can press the pressing plates 11 on both sides and move them into the fixing slot 12, so that the two pressing plates 11 squeeze the front and rear telescopic rods 15 and springs 16 respectively. Then the user can insert the left end of the fixing plate 8 into the fixing frame 10 and release the two pressing plates 11 when the holographic glasses 7 are adjusted to a suitable position. At this time, the elastic force of the two sets of springs 16 is used to push the two pressing plates 11 away from each other, so that the fixing holes 14 at the corresponding positions on the two pressing plates 11 are plugged into the fixing rods 13 to fix the positions of the fixing plates 8 and the holographic glasses 7. Then the holographic glasses 7 are connected to the control host 9 by a data cable, so that the control host 9 converts the wearer's heart sound data into images and transmits them to the holographic glasses 7 for display.

[0044] When using this device, the user can press the cover 19 backward so that the cover 19 squeezes the silicone airbag, and then twist the cover 19 forty-five degrees so that the cover 19 rotates to correspond to the connecting groove 35. At this time, the user can pull the cover 19 forward so that the slider 32 disengages from the annular slide groove 36, thereby removing the cover 19 to clean the mesh plate 22, and the user can also disassemble and replace the fixing seat 30 and the mounting ring 28, and maintain the speaker 27.

[0045] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
