Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, and more particularly to a constant force percussion type otolaryngology hearing testing device. Background Technology

[0002] Traditional ENT hearing tests often use tuning forks or manual percussion instruments to generate sound stimulation for preliminary assessment of a patient's hearing status. However, these methods have significant limitations. The intensity, frequency, and rhythm of the sound are highly dependent on the operator's technique, force, and skill level, resulting in poor repeatability and strong subjectivity in the test results. It is difficult to achieve standardization and quantitative comparison. Manual operation cannot guarantee that each strike will produce completely consistent sound energy, which directly affects the accuracy of judging the patient's hearing threshold. In addition, during the test, the device positioning needs to be manually adjusted, and there is a lack of effective protection mechanism for the patient's head, posing a risk of accidental collision. At the same time, environmental noise can easily interfere with the purity and transmission efficiency of the sound signal, further reducing the reliability of the test.

[0003] Therefore, a constant force percussion type ENT hearing testing device is now being developed to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of existing devices during use, the present invention provides a constant force percussion type ENT hearing testing device.

[0006] Furthermore, the pulley assembly includes: A pulley, which is slidably connected to the first mounting component; A contact element, the contact element being connected to the output shaft of the first drive motor; A protrusion, which is mounted on the rear side of the pulley and is pushed by the adjacent contact member; A wedge-shaped component, which is installed on the rear side of the corresponding pulley and moves forward when squeezed by the adjacent contact component; A first spring is installed between the pulley and the first mounting member; A belt, the belt being wound around the corresponding pulley.

[0007] Furthermore, the impact assembly includes: The guide rail is installed on the lower part of the first mounting component; A sliding element, which is slidably connected to the guide rail and connected to the adjacent belt; A striker, the striker being connected to the inner side of an adjacent slider; A second spring is connected between the slider and the adjacent first mounting member.

[0008] Furthermore, the sound-generating component includes: A second mounting component is mounted on the bottom of an adjacent first mounting component; Mounting base, the mounting base being installed inside the adjacent second mounting member; A cross arm is mounted on a corresponding mounting base and is capable of generating sound by being struck by a corresponding impact head.

[0009] Furthermore, it also includes a moving mechanism, which includes: The second drive motor is mounted on the upper right side of the first mounting plate; A dual-axis lead screw, which is mounted on the output shaft of the second drive motor and threadedly connected to the first mounting component; The third mounting plate is installed on the upper left side of the first mounting plate and is rotatably connected to the dual-axis lead screw.

[0010] Furthermore, it also includes a collision avoidance mechanism, which includes: An arc-shaped plate is slidably installed on the lower side of the middle part of the first mounting plate, and the arc-shaped plate is used to protect the patient's head; A damper is installed between the arc-shaped plate and the first mounting plate; A third spring is installed between the arc-shaped plate and the damper.

[0011] Furthermore, it also includes a sound-focusing mechanism, which comprises: A first acoustic focusing plate is installed on the rear side of the arc-shaped plate; The second sound-concentrating plate is rotatably mounted on the front side of the arc-shaped plate; The sound-receiving structure is located at the junction of the second sound-collecting plate and the first sound-collecting plate, at the patient's ear position; A damping ring is disposed between the second acoustic plate and the arc-shaped plate.

[0012] Furthermore, it also includes a protective structure, the protective mechanism comprising: A protective component, which is installed on the first mounting component, is used to protect the cross arm; Rib plate, the rib plate being installed on the underside of the protective component.

[0013] Furthermore, it also includes an auxiliary gripping structure, which includes patches. The patches are provided on the handles of the first mounting plate, and each patch has a through hole.

This invention achieves constant force automatic striking of the cross arm through a precision mechanical system consisting of a first drive motor, a pulley assembly, a spring, and a striker. This eliminates the errors introduced by inconsistent force and angle in traditional manual operation. The sound energy generated by each strike is highly consistent, thereby greatly improving the accuracy, repeatability, and objectivity of hearing test results and providing doctors with a stable and reliable diagnostic basis.

[0016] 2. This invention enables the electric drive of the sound-generating assembly to move horizontally as a whole through a moving mechanism. Combined with the flexibility of the robotic arm, this allows for rapid and precise adjustment of the detection head position. The arc-shaped plate, damper, and spring in the anti-collision mechanism constitute a passive safety system that effectively buffers kinetic energy upon contact with the patient, preventing discomfort or injury from hard collisions and significantly improving the safety of the equipment and patient comfort during the examination process.

[0017] 3. This invention forms an acoustic cavity pointing towards the patient's ear canal by splicing a first sound-focusing plate and a second sound-focusing plate. This effectively focuses the sound waves generated by the impact of the head, reduces the loss of sound energy diffusion, and isolates environmental noise interference to a certain extent. This ensures that the sound signal transmitted to the patient's ear is clear, pure, and stable in intensity. The damping ring ensures that the angle of the sound-focusing plate is adjustable and the positioning is stable, further optimizing the acoustic transmission efficiency and ensuring the standardization of the testing environment.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1 A constant-force percussion hearing testing device for otolaryngology, such as Figures 1-10 As shown, the system includes a first mounting plate 1, a second mounting plate 2 mounted on the upper side of the first mounting plate 1, a robotic arm 3 mounted on the second mounting plate 2, a mounting component on the top of the robotic arm 3 for fixed installation, a first mounting component 4 slidably mounted on the first mounting plate 1, a first drive motor 5 mounted on the lower front side of the first mounting component 4, a pulley assembly 6 disposed between the output shafts of the first drive motor 5, an impact component 7 slidably mounted on the first mounting component 4 and connected to the pulley assembly 6, and a sound-generating component 8 disposed on the first mounting component 4, which can emit sound when struck by the impact component 7.

[0031] The pulley assembly 6 includes a pulley 61, which is slidably connected to the first mounting member 4. A contact member 62 is connected to the output shaft of the first drive motor 5. A protrusion 63 is installed on the rear side of the pulley 61 and is pushed by the adjacent contact member 62. A wedge 64 is installed on the rear side of the corresponding pulley 61 and moves forward after being squeezed by the adjacent contact member 62. A first spring 65 is installed between the pulley 61 and the first mounting member 4. A belt 66 is wound around the corresponding pulley 61.

[0032] The impact assembly 7 includes a guide rail 71, which is mounted on the lower part of the first mounting member 4. A slider 72 is slidably connected to the guide rail 71 and connected to the adjacent belt 66. The impact head 73 is connected to the inner side of the adjacent slider 72. A second spring 74 is connected between the slider 72 and the adjacent first mounting member 4.

[0033] The sound-generating component 8 includes a second mounting member 81, which is mounted on the bottom of an adjacent first mounting member 4. A mounting base 82 is mounted on the inner side of the adjacent second mounting member 81. A cross arm 83 is disposed on the corresponding mounting base 82 and can generate sound by being struck by the corresponding bumper 73.

[0034] It should be noted that, firstly, the device is fixed in a suitable position in the detection environment by the mounting bracket at the top of the robotic arm 3. The robotic arm 3 is mounted on the second mounting plate 2, which in turn is fixed to the upper side of the first mounting plate 1, thus providing a stable support base. During detection, the first drive motor 5 is started, and its output shaft drives the contact member 62 fixed thereon to rotate at a constant speed. When the contact member 62 rotates to contact the protrusion 63 on the rear side of a specific pulley 61, it pushes the protrusion 63, thereby driving the pulley 61 to rotate. The belt 66, which is connected to it, is rotated and tightened. The sliding member 72, connected to the other end of the belt 66, is thus pulled and slides outward (away from the sound-generating assembly 8) along the guide rail 71 fixed to the lower part of the first mounting member 4. During this process, the second spring 74 connected between the sliding member 72 and the first mounting member 4 is gradually stretched, converting kinetic energy into elastic potential energy and storing it. Immediately after the rotating contact member 62 disengages from the protrusion 63, it immediately contacts the inclined surface of the wedge-shaped member 64 mounted on the rear side of the same pulley 61. Under the continuous rotation and compression of 62, the wedge 64 drives the entire pulley 61 to slide forward (towards the motor) a short distance, overcoming the resistance of the first spring 65. This forward movement causes the belt 66 to relax instantly, releasing the traction constraint on the slider 72. At this instant, the elastic potential energy stored in the stretched second spring 74 is immediately released, generating a strong restoring force, driving the slider 72 to accelerate at high speed along the guide rail 71 inward (towards the sound-generating component 8). The bumper 73 fixed inside the slider 72 then strikes the cross arm 83 installed in the sound-generating component 8 at extremely high speed. After being subjected to this constant impact force, the cross arm 83 generates a damped vibration at a specific frequency, thereby emitting a standardized sound signal for hearing detection. After the impact is completed, the drive motor continues to rotate, the contact 62 disengages from the wedge 64, the pulley 61 resets under the action of the first spring 65, and the slider 72 stops moving under the damping action of the second spring 74. The system returns to its initial state, waiting for the contact 62 to contact the protrusion 63 again, starting a new working cycle.

[0035] Example 2 Based on Embodiment 1, a moving mechanism 9 is also included. The moving mechanism 9 includes a second drive motor 91, which is mounted on the upper right side of the first mounting plate 1. A dual-axis lead screw 92 is mounted on the output shaft of the second drive motor 91 and is threadedly connected to the first mounting member 4. A third mounting plate 93 is mounted on the upper left side of the first mounting plate 1 and is rotatably connected to the dual-axis lead screw 92.

[0036] It also includes an anti-collision mechanism 10, which includes an arc plate 101. The arc plate 101 is slidably installed on the lower side of the middle of the first mounting plate 1. The arc plate 101 is used to protect the patient's head. A damper 102 is installed between the arc plate 101 and the first mounting plate 1. A third spring 103 is installed between the arc plate 101 and the damper 102.

[0037] It also includes a sound focusing mechanism 11, which includes a first sound focusing plate 111, which is installed on the rear side of the arc plate 101. A second sound focusing plate 113 is rotatably installed on the front side of the arc plate 101. The second sound focusing plate 113 is spliced ​​with the first sound focusing plate 111. A sound receiving structure 112 is located at the splice between the second sound focusing plate 113 and the first sound focusing plate 111, at the patient's ear position. A damping ring 114 is located between the second sound focusing plate 113 and the arc plate 101.

[0038] The operator first activates the second drive motor 91 in the moving mechanism 9. This motor is mounted on the upper right side of the first mounting plate 1, and its output shaft drives the dual-axis lead screw 92 to rotate. Since the dual-axis lead screw 92 is threadedly connected to the first mounting member 4 that supports the core component, and the other end of the lead screw is rotatably supported on the upper left side of the first mounting plate 1 via the third mounting plate 93, the rotational motion is converted into the horizontal movement of the first mounting member 4, together with the first drive motor 5, the impact component 7, and the sound-generating component 8, along the lead screw axis, thereby... The sound-generating component 8 is initially positioned near the patient's head. As the device approaches the patient, the arc-shaped plate 101, which is slidably mounted on the lower side of the middle of the first mounting plate 1, slides upon contact with the patient's head surface, compressing the damper 102 mounted between it and the first mounting plate 1, as well as the third spring 103 sleeved on the damper 102. The damper 102 rapidly absorbs the impact kinetic energy through hydraulic or pneumatic principles, while the third spring 103 provides gentle elastic cushioning, together forming a progressive cushioning system that effectively prevents rigid impacts. The impact could cause discomfort or injury to the patient. Simultaneously, the curved design of the arc-shaped plate 101 better conforms to the head contour, improving comfort and safety. Once the arc-shaped plate 101 is properly positioned, the first sound-concentrating plate 111, fixedly installed on the rear side of the arc-shaped plate 101, and the second sound-concentrating plate 113, rotatably installed on the front side of the arc-shaped plate 101 via a damping ring 114, together surround the patient's ear. The second sound-concentrating plate 113 can be finely adjusted to adapt to different head shapes and maintains a stable position through the frictional resistance within the damping ring 114. The first sound-concentrating plate... The first 111 and the second sound-gathering plate 113 are spliced ​​together in front to form an acoustic cavity that partially surrounds the ear. The sound-receiving structure 112 located at the splice point, directly opposite the ear canal, is responsible for subsequent monitoring of sound signals. This sound-gathering cavity can effectively gather the sound waves generated by the impact, reduce the diffusion loss to the surrounding environment, and guide the sound more concentratedly to the ear canal. At the same time, it isolates environmental noise interference to a certain extent, thereby significantly improving the clarity and intensity of the sound signal transmitted to the patient's auditory system, providing a reliable acoustic environment for obtaining accurate hearing thresholds.

[0039] It also includes a protective structure 12, the protective mechanism including a protective component 121, the protective component 121 is installed on the first mounting component 4 for protecting the cross arm 83, and the rib plate 122 is installed on the underside of the protective component 121.

[0040] It also includes an auxiliary gripping structure 13, which includes a patch 131. The first mounting plate 1 has a patch 131 on its handle, and each patch 131 has a through hole 132.

[0041] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
