Description

Technical Field

[0001] The invention relates to the field of medical equipment, and more particularly to a bidirectional physical examination percussion hammer. Background Art

[0002] The percussion hammer is a commonly used medical device in internal medicine. It is used to tap certain parts of the body during percussion so that the doctor can judge whether the part is normal based on the nature of the sound and the interval time. It can also be used to determine the pathological condition of the organ boundary and diagnose whether the nerve reflexes of the corresponding parts are normal.

[0003] There are many usage specifications for percussion hammers in clinical use, such as:

[0004] ‌Holding method‌: Hold the percussion hammer between the thumb and index finger, and tap the tendon or periosteum quickly with appropriate strength. Use the wrist joint as the axis, flex the wrist 30° when tapping, and increase the speed of the distal end of the percussion hammer to increase the force of the tapping‌.

[0005] ‌Percussion force‌: The force of the percussion hammer should be moderate, not too strong or too weak. Too strong a force will cause pain and affect the examination results; too weak a force may not result in clear audio feedback‌.

[0006] ‌Tapping skills‌: When tapping, the wrist joint and metacarpophalangeal joint should be the main movement, and the elbow and shoulder joints should not be involved in the movement. The tapping movement should be flexible, short and elastic. After tapping, the middle finger of the right hand should be raised immediately to avoid affecting the judgment of the percussion sound.

[0007] In actual use, if you want to accurately grasp the above standards and perform accurate percussion, there are high requirements for medical personnel. For doctors with insufficient medical experience, it is easy for medical personnel to misdiagnose due to non-standard operations. In addition, different people have different subjective judgments on the strength of percussion, and standardized percussion cannot be achieved, which further increases the diagnostic error when using the percussion hammer.

[0026] By setting up a self-replacement component for the isolation sleeve, after the percussion is completed, the new isolation sleeve can be automatically replaced by utilizing the recovery and reset action of the knocking rod and the knocking head, thereby improving the replacement efficiency of the isolation sleeve, simplifying the percussion process, and improving the percussion efficiency.

[0027] By setting up permanent magnets and electromagnets, percussion may need to be performed multiple times on the same patient to ensure the correct judgment of the percussion sound. In this case, the isolation sleeve does not need to be replaced. At this time, the electromagnet can be energized through the control panel to generate a magnetic field and adsorb the permanent magnet, driving the inverted plate to overcome the resistance of the torsion spring and fit the electromagnet, so that during the recovery and reset process of the knocking rod and the knocking head, the ratchet ring will not drive the receiving roller to rotate, ensuring that the replacement belt will not move at this time, thereby achieving the purpose of saving the isolation sleeve.

[0028] By setting up the old sleeve separation component, when the old isolation sleeve needs to be removed, the knocking rod and the knocking head are reset, and air is no longer released through the No. 1 air release port. The solenoid valve on the No. 1 air release port is closed, and the solenoid valve inside the No. 2 air release port is opened. The gas inside the elastic airbag enters the No. 2 gas channel through the No. 1 gas channel, and is finally ejected from the isolation sleeve jet drop hole to blow off the old isolation sleeve on the knocking head, thereby achieving the purpose of automatic removal of the old isolation sleeve, reducing the possibility of infection caused by manual operation of medical staff, and at the same time reducing the percussion process of medical staff.

[0054] like Figures 1 to 11 As shown, an embodiment of the present invention provides a bidirectional physical examination percussion hammer, including a handle No. 1 1, a handle No. 2 2 and a hinged portion 3, wherein the handle No. 1 1 and the handle No. 2 2 are cross-arranged, and the top ends are rotatably connected through the hinged portion 3; the upper end of the hinged portion 3 is fixedly connected to a striking assembly.

[0055] The knocking assembly includes a main shell 4 fixedly connected to the upper end of the hinge part 3, the left outer surface of the main shell 4 is fixedly connected to the micro air pump 6, the inner side of the main shell 4 is fixedly connected to the partition plate 13, and an air storage cavity is formed between the left side of the partition plate 13 and the main shell 4, the micro air pump 6 is connected to the air storage cavity through a pipeline, and an air injection port 14 is provided in the middle position of the partition plate 13, the right outer surface of the partition plate 13 is fixedly connected to an elastic air bag 16, and the air storage cavity on the left side of the partition plate 13 is connected to the elastic air bag 16 through the air injection port 14, and the partition plate 13 is also provided with a first air release port 15 for connecting the elastic air bag 16 with the outside world; the right end of the elastic air bag 16 is fixedly connected to a sliding push plate 17, the right outer surface of the sliding push plate 17 is fixedly connected to a knocking rod 18, and the right end of the knocking rod 18 is fixedly connected to a knocking head 19.

[0056] The knocking assembly also includes four sets of return assemblies arranged in a rectangular shape on the right side surface of the partition plate 13.

[0057] An active opening 20 is provided on the right outer surface of the main shell 4 , and an infrared distance measuring sensor 11 is provided on one side of the right outer surface of the main shell 4 .

[0058] like Figure 4 As shown, the return assembly includes a slide rod 25 with one end fixedly connected to the right side surface of the partition plate 13 and the other end passing through the sliding push plate 17 and fixedly connected to the inner wall of the main shell 4. A return spring 26 is also fixedly connected between the partition plate 13 and the sliding push plate 17, and the slide rod 25 passes through the return spring 26.

[0059] like Figure 1 and Figure 3 As shown, solenoid valves are provided inside the No. 1 air vent 15 and the air injection port 14, a battery 7 is also provided on the left outer surface of the main shell 4, a control panel 5 is provided on one side of the upper surface of the main shell 4, and an air pressure sensor 12 is provided on the bottom wall of the air storage cavity inside the main shell 4.

[0060] When performing percussion, firstly, the No. 1 handle 1 and the No. 2 handle 2 are rotated and fitted together using the hinge 3, and then the medical staff holds the No. 1 handle 1 and the No. 2 handle 2 and moves the device to the position where percussion is required. During this process, the infrared distance sensor 11 will continue to work. When the device moves to the height required for percussion, the infrared distance sensor 11 will transmit a signal to the control panel 5. The medical staff observes the information provided by the control panel 5 to stop the movement of the device, so that the device is kept at a suitable percussion height. Then, the medical staff operates the control panel 5 with the other hand to control the knocking component to start working;

[0061] The specific process of tapping the component is as follows:

[0062] The battery 7 supplies power to the micro air pump 6, which pumps outside air into the air storage chamber, increasing the air pressure inside the air storage chamber. During this process, the air pressure sensor 12 monitors the air pressure strength inside the air storage chamber in real time. The specific air pressure strength required can be determined according to the required percussion strength. There is a positive proportional relationship between the air pressure strength and the percussion strength. When the air pressure strength reaches the required requirement, the control panel 5 can be used to control the solenoid valve inside the air injection port 14 to open (the solenoid valve is closed during the air storage stage). At this time, the pressurized gas inside the air storage chamber enters the elastic airbag 16, causing the elastic airbag 16 to It rapidly expands and pushes the sliding push plate 17 to move to the right inside the main shell 4, while driving the knocking rod 18 and the knocking head 19 to extend to the right from the active opening 20, and quickly knocks on the patient. The medical staff makes relevant judgments on the patient's condition through the percussion sound. In this process, the sliding push plate 17 will drive the reset spring 26 to extend and store elastic potential energy. After the knocking is completed, the solenoid valve inside the No. 1 air relief port 15 opens to release the pressure on the gas inside the elastic airbag 16. The elastic airbag 16 retracts to its initial state driven by the elastic potential energy of the reset spring 26, completing a percussion work.

[0063] By setting up a knocking component, the present invention can standardize the knocking height and the knocking force when performing percussion, so that the percussion standard is more unified, which can greatly avoid the problem of misdiagnosis caused by some doctors with insufficient medical experience due to improper operation. At the same time, due to the automatic control of the knocking force, it can also avoid the problem that different medical personnel have different judgments on the percussion force and cannot perform standardized percussion, and can reduce the diagnostic error when the percussion hammer is used.

[0064] like Figure 3 , Figures 5 to 8As shown, the main shell 4 is also provided with an isolation sleeve self-replacement component 8 near the movable opening 20, and the isolation sleeve self-replacement component 8 includes a box body 81 fixedly connected to the upper surface of the main shell 4, the inner wall of the box body 81 is rotatably connected to a discharge roller 812, and a replacement belt 82 is wound around the discharge roller 812. The right side of the lower surface of the main shell 4 is rotatably connected to a guide roller 84, and the lower surface of the main shell 4 is also provided with a receiving roller 85, one end of the replacement belt 82 passes through the main shell 4 and is guided by the guide roller 84 and then wound around the receiving roller 85; the guide roller 84 is The end is fixedly connected to the No. 1 bevel gear 86, one side of the No. 1 bevel gear 86 is meshed with the No. 2 bevel gear 87, the upper end of the No. 2 bevel gear 87 is fixedly connected to the rotating rod 88, and the rotating rod 88 is rotatably connected to the main shell 4 through a bearing, the upper end of the rotating rod 88 extends to the inside of the main shell 4 and is fixedly connected to the No. 3 bevel gear 89, one end of the No. 3 bevel gear 89 is meshed with the No. 4 bevel gear 810, one end of the No. 4 bevel gear 810 is fixedly connected to the rotating shaft 811, and the rotating shaft 811 is rotatably connected to the inner wall of the main shell 4, and a one-way winding component 83 is arranged on the rotating shaft 811.

[0065] The one-way winding assembly 83 includes a meshing ring 813 linearly and evenly fixed to the outer cylindrical surface of the knocking rod 18, and a transmission cylinder 831 fixed to the outer cylindrical surface of the rotating shaft 811. The outer cylindrical surface of the rotating shaft 811 is also rotatably connected to two groups of supporting rings 834, and the opposite sides of the two groups of supporting rings 834 are commonly fixed to a meshing gear 832, and the meshing gear 832 is meshed with the meshing ring 813. The inner wall of the meshing gear 832 is fixed with a ratchet ring 833. The outer surface of the transmission cylinder 831 is provided with a torsion spring 836, and is rotatably connected to a buckle plate 835 through the torsion spring 836. The buckle plate 835 and the ratchet ring 833 cooperate with each other.

[0066] like Fig.10 As shown, the replacement belt 82 includes a belt base belt 821 wound around the outer surfaces of the unwinding roller 812, the guide roller 84 and the receiving roller 85, and an isolation sleeve assembly is evenly arranged on the belt base belt 821. The isolation sleeve assembly includes an elastic hoop 822 bonded to the belt base belt 821, and the elastic hoop 822 is fixedly connected to the isolation sleeve 823.

[0067] When the knocking head 19 returns from the fully extended knocking state to the fully retracted initial state, the isolation sleeve self-replacement assembly 8 drives the replacement belt 82 to move the distance of an isolation sleeve assembly.

[0068] During percussion, the percussion head 19 contacts different patients, and the germs carried during percussion may cause cross infection between patients. Therefore, it is usually necessary to manually replace the isolation cover of the percussion head 19. In this process, not only is the operation cumbersome and inefficient, but it is also easy to increase the infection of medical staff.

[0069] By setting the isolation sleeve self-replacement component 8, after the percussion is completed, the elastic airbag 16 will drive the knocking rod 18 and the knocking head 19 to reset during the deflation recovery process. During this process, the knocking rod 18 will drive the meshing ring 813 to reset to the left synchronously. During the left reset process of the meshing ring 813, the meshing gear 832 meshed with it will be driven to rotate. The meshing gear 832 will drive the two supporting rings 834 to rotate on the outer cylindrical surface of the rotating shaft 811. At the same time, the meshing gear 832 will drive the ratchet gear ring 833 fixed thereto to rotate counterclockwise ( Figure 8 When the ratchet ring 833 rotates, the undercut plate 835 engaged on the ratchet rotates. The undercut plate 835 drives the transmission cylinder 831 and the rotating shaft 811 to rotate through the torsion spring 836. When the rotating shaft 811 rotates, it drives the No. 4 bevel gear 810 fixed thereto to transmit, and then drives the No. 3 bevel gear 89 meshing therewith to rotate. The No. 3 bevel gear 89 is fixedly connected to the No. 2 bevel gear 87 through the rotating rod 88, so it synchronously drives the No. 2 bevel gear 87 to rotate, and finally drives the No. 1 bevel gear 86 meshing with the No. 2 bevel gear 87 to rotate. When the No. 1 bevel gear 86 rotates, it drives the receiving roller 8 5 rotates to wind up the replacement belt 82, the belt body base belt 821 moves, driving the used isolation sleeve assembly to move downward, and the unused isolation sleeve assembly moves to the preparation station. When a new percussion is performed next time, the new isolation sleeve assembly will be pushed out by the ejection force of the knocking head 19 during the extension of the knocking rod 18 and the knocking head 19, and separated from the belt body base belt 821. At the same time, the elastic hoop 822 drives the isolation sleeve 823 to be sleeved on the knocking head 19 through the contraction force of the elastic hoop 822, completing the replacement operation of the isolation sleeve 823.

[0070] It should be noted here that, during the process of the knocking rod 18 and the knocking head 19 extending out to knock, the ratchet ring 833 rotates clockwise. In this state, the inverted plate 835 will not engage with the ratchet ring 833, but will use the torsion spring 836 to continuously pass through the ratchet ring 833. At this time, the inverted plate 835 cannot drive the transmission cylinder 831 and the rotating shaft 811 to rotate, so it will not drive the movement of the replacement belt 82, thereby ensuring that the isolation sleeve assembly newly entering the work station will not be moved, thereby ensuring the accurate replacement of the new isolation sleeve.

[0071] The present invention provides a self-replacement isolation sleeve assembly 8, which can automatically replace the new isolation sleeve 823 by utilizing the recovery and reset action of the knocking rod 18 and the knocking head 19 after the percussion is completed, thereby improving the replacement efficiency of the isolation sleeve 823, simplifying the percussion process, and improving the percussion efficiency.

[0072] like Fig. 9 As shown, a permanent magnet 837 is provided on one side of the inverted plate 835 , and an electromagnet 838 is embedded at a corresponding position on the outer surface of the transmission cylinder 831 .

[0073] During operation, percussion may need to be performed multiple times on the same patient to ensure the correct judgment of the percussion sound. In this case, the isolation sleeve 823 does not need to be replaced. At this time, the electromagnet 838 can be energized through the control panel 5 to generate a magnetic field and adsorb the permanent magnet 837, driving the inverted plate 835 to overcome the resistance of the torsion spring 836 and fit the electromagnet 838, so that during the recovery and reset process of the knocking rod 18 and the knocking head 19, the ratchet ring 833 will not drive the receiving roller 85 to rotate, ensuring that the replacement belt 82 will not move at this time, and the new isolation sleeve assembly will not enter the work station, thereby achieving the purpose of saving the isolation sleeve 823.

[0074] like Fig.11 As shown, the knocking rod 18 and the knocking head 19 are also provided with an old sleeve separation component, and the old sleeve separation component includes a No. 1 gas channel 22 which runs through the inside of the knocking rod 18, and a No. 2 gas channel 23 is opened inside the knocking head 19, and the No. 1 gas channel 22 is connected with the No. 2 gas channel 23. The knocking head 19 is also provided with evenly distributed isolation sleeve jet shedding holes 24 in a ring shape around the No. 2 gas channel 23, and the isolation sleeve jet shedding holes 24 are connected with the No. 2 gas channel 23, and the isolation sleeve jet shedding holes 24 are inclined.

[0075] The old sleeve separation assembly also includes a second air vent 21 which is arranged on the sliding push plate 17 and connects the elastic air bag 16 with the first gas channel 22 , and a solenoid valve is also arranged in the second air vent 21 .

[0076] During operation, the isolation sleeve self-replacement component 8 is provided to realize the automatic replacement of the new isolation sleeve body 823. However, the old isolation sleeve body 823 still needs to be removed manually, which is easy to cause infection to medical staff and increase the workload of medical staff. By providing the old sleeve separation component, when the old isolation sleeve body 823 needs to be removed (it should be noted that the electromagnet 838 is not working at this time, and the isolation sleeve self-replacement component 8 is in working state), the knocking rod 18 and the knocking head 19 are reset, and they are no longer The air is released through the No. 1 air release port 15, and the solenoid valve on the No. 1 air release port 15 is closed. At this time, the solenoid valve inside the No. 2 air release port 21 is opened, and the gas inside the elastic airbag 16 enters the No. 2 gas channel 23 through the No. 1 gas channel 22, and is finally ejected from the isolation sleeve jet drop-off hole 24, blowing off the old isolation sleeve body 823 on the percussion head 19, thereby achieving the purpose of automatically removing the old isolation sleeve body 823, reducing the possibility of infection caused by manual operation of medical personnel, and at the same time reducing the percussion process of medical personnel.

[0077] like Figure 1 and Figure 2As shown, a triangular acupuncture tip 10 is provided at the end of the No. 1 handle 1, and a wound measurement scale line 9 is provided on the side surface of the No. 1 handle 1, wherein the triangular acupuncture tip 10 can be used for the patient's acupuncture sensation examination, and the wound measurement scale line 9 can be used to determine the patient's wound size, thereby ensuring the versatility of the device.

[0078] The workflow of the technical solution of the present invention is as follows:

[0079] First, handle No. 1 1 and handle No. 2 2 are rotated and fitted using the hinge 3, and then the medical staff holds handle No. 1 1 and handle No. 2 2 and moves the device to the position where percussion is required. During this process, the infrared ranging sensor 11 will continue to work. When the device moves to the height required for percussion, the infrared ranging sensor 11 will transmit a signal to the control panel 5. The medical staff observes the information provided by the control panel 5 to stop the movement of the device, so that the device remains at a suitable percussion height. Then, the medical staff operates the control panel 5 with the other hand to control the knocking component to start working.

[0080] The specific process of tapping the component is as follows:

[0081] The battery 7 supplies power to the micro air pump 6, which pumps outside air into the air storage chamber, increasing the air pressure inside the air storage chamber. During this process, the air pressure sensor 12 monitors the air pressure strength inside the air storage chamber in real time. The specific air pressure strength required can be determined according to the required percussion strength. There is a positive proportional relationship between the air pressure strength and the percussion strength. When the air pressure strength reaches the required requirement, the control panel 5 can be used to control the solenoid valve inside the air injection port 14 to open (the solenoid valve is closed during the air storage stage). At this time, the pressurized gas inside the air storage chamber enters the elastic airbag 16, causing the elastic airbag 16 to It rapidly expands and pushes the sliding push plate 17 to move to the right inside the main shell 4, while driving the knocking rod 18 and the knocking head 19 to extend to the right from the active opening 20, and quickly knocks on the patient. The medical staff makes relevant judgments on the patient's condition through the percussion sound. In this process, the sliding push plate 17 will drive the reset spring 26 to extend and store elastic potential energy. After the knocking is completed, the solenoid valve inside the No. 1 air relief port 15 opens to release the pressure on the gas inside the elastic airbag 16. The elastic airbag 16 retracts to its initial state driven by the elastic potential energy of the reset spring 26, completing a percussion work.
