[0002] "Otorhinolaryngology" is a surgical discipline that diagnoses and treats the ear, nose, pharynx, larynx, and related head and neck areas. With the advancement and development of science and technology, various medical disciplines have penetrated and promoted each other, expanding the scope of otolaryngology. The emergence of ear microsurgery, ear neurosurgery, skull base surgery, audiology and balance science, nasal endoscopic surgery, nasal neurosurgery, head and neck surgery, laryngeal microsurgery, voice and speech disease department, pediatric otolaryngology, etc., has enriched the content of otolaryngology.

[0003] Hearing refers to the ability to activate the auditory organs and receive voice information. If there is a hearing problem, you need to go to the ENT department of the hospital for examination. The otolaryngologist will conduct different hearing tests based on the patient's condition. One of the test methods is that the otolaryngologist rings bells at different locations around the patient, and the patient judges the direction based on the sound of the bell, thereby testing the patient's hearing.

[0004] For example, Chinese invention patent CN108670265B proposes a patient hearing test device for otolaryngology, including a bottom plate, a first annular slide rail, a first annular slider, a hollow disc, a gear ring, a first motor, a gear, a first bracket, a box, a first slide rail, a first slider, a first support rod, a copper ball, a support plate, a first spring, a second spring, an iron sheet, a second motor, a turntable, a pin rod, a support leg and a seat plate. The bottom plate is connected to the first annular slide rail, the first annular slide rail is provided with a first annular slider, the top of the first annular slider is connected to a hollow disc, the inner side wall of the hollow disc is connected to a gear ring, the left side of the bottom plate is connected to the first motor, the first motor is located in the first annular slide rail, the output shaft of the first motor is connected to the gear through a coupling, and the gear is meshed with the gear ring.

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides an otolaryngology hearing test device having the following features:

[0025] Beneficial effects:

[0026] 1. The hearing test equipment for otolaryngology is provided with a steering motor and a transverse movement component, so that the steering motor can drive the vibration sound-generating component to steer, and the transverse movement component can drive the vibration sound-generating component to move outward or inward. Before conducting a hearing test, the vibration sound-generating component can be moved to a suitable position for testing by the steering motor and the transverse movement component, so that the vibration sound-generating component can be moved to different angles and distances according to the requirements of the hearing test, thereby greatly improving the test range of the test equipment. In addition, when conducting a hearing test, the steering motor can be used to drive the swing arm to swing back and forth at a smaller angle, so that the swing arm can drive the vibration sound-generating component to swing back and forth, so that the vibration sound-generating component can passively generate sound, and can generate sound without the need for additional driving components to drive the vibration sound-generating component, thereby improving the reliability of the vibration sound-generating component.

[0027] 2. The hearing test equipment for otolaryngology is provided with a swing arm control component, which can drive the swing arm to turn and swing. When conducting a hearing test, the swing arm control component can drive the swing arm to rotate so that the swing arm can turn freely. Compared with a steering motor, this steering method can more accurately control the steering angle and improve the test accuracy of the hearing test equipment. In addition, the swing arm control component can also drive the vibration and sound-generating component to swing back and forth, so that the vibration and sound-generating component makes a sound. Since the swing arm control component directly drives the swing arm to swing, the vibration amplitude of the vibration and sound-generating component can be increased, thereby increasing the size of the sound emitted by the vibration and sound-generating component, further improving the test range of the equipment.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] In the related art, two motors are used to drive the position of the sound-generating mechanism and the sound of the sound-generating mechanism respectively, which reduces the reliability of the test equipment and the test range of the hearing test equipment is not high.

[0045] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a hearing test device for otolaryngology. By setting a steering motor and a lateral movement assembly, the steering motor can drive the vibration and sound-generating assembly to turn, and the lateral movement assembly can drive the vibration and sound-generating assembly to move outward or inward. Before conducting a hearing test, the vibration and sound-generating assembly can be moved to a suitable position for testing through the steering motor and the lateral movement assembly, so that the vibration and sound-generating assembly can be moved to different angles and distances according to the requirements of the hearing test, thereby greatly improving the test range of the test equipment. In addition, when conducting a hearing test, the steering motor can be used to drive the swing arm to swing back and forth at a smaller angle, so that the swing arm can drive the vibration and sound-generating assembly to swing back and forth, so that the vibration and sound-generating assembly can passively make sounds, and no additional driving components are required to drive the vibration and sound-generating assembly to make sounds, thereby improving the reliability of the vibration and sound-generating assembly.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] Combination Figure 1-Figure 4 , the embodiment of the present application provides a hearing test device for otolaryngology, including a hearing test seat 10 arranged in the otolaryngology department; a steering motor 20 is arranged directly above the hearing test seat 10;

[0048] The hearing test seat 10 is arranged directly below the steering motor 20. When the test is performed, the tester sits on the hearing test seat 10 for the test; the steering motor 20 can drive the swing rod 50 to turn, so that the swing rod 50 rotates in the horizontal direction (see the attached Figure 1 ), when conducting the test, by rotating the swing rod 50 horizontally to different directions, the tester can feedback the test result according to the rotation direction of the vibration sound generating component 60;

[0049] The output shaft of the steering motor 20 is fixedly connected to the traverse assembly 30, and the traverse assembly 30 includes: a traverse frame 31; a mounting seat 32, fixedly connected to the top of the traverse frame 31, and fixedly connected to the output shaft of the steering motor 20; a traverse motor 33, installed at one end of the traverse frame 31; a lead screw 34, rotatably connected to the inside of the traverse frame 31, and one end of which is connected to the output shaft of the traverse motor 33; a lead screw nut 35, slidably connected to the outer side wall of the lead screw 34; a sliding block 36, slidably connected to the bottom of the traverse frame 31, and fixedly connected to the bottom of the lead screw nut 35;

[0050] Before the test, the lateral movement assembly 30 can be moved to drive the swing rod 50 to lateral movement, so that the vibration sound generating assembly 60 at one end of the swing rod 50 can be moved away from or close to the hearing test seat 10 (see the attached Figure 1 ), when the test difficulty needs to be increased, the vibration sound-generating component 60 can be moved outward to make the vibration sound-generating component 60 away from the tester to increase the test difficulty, thereby increasing the range of the hearing test. When the horizontal movement is performed, the horizontal movement motor 33 drives the lead screw 34 to rotate, so that the lead screw 34 drives the lead screw nut 35 to move horizontally, and the lead screw nut 35 then drives the swing rod 50 at the bottom of the sliding block 36 to move horizontally (according to the hearing test requirements, the vibration sound-generating component 60 is used for the hearing test at 2 meters, 4 meters or 6 meters);

[0051] A frequency conversion controller 40 is installed on the outer side wall of the transverse movement assembly 30;

[0052] The frequency conversion controller 40 is electrically connected to the steering motor 20, the traverse motor 33 and the swing motor 71 respectively, and is used to accurately control the rotation of the steering motor 20, the traverse motor 33 and the swing motor 71;

[0053] The output end of the traverse assembly 30 is provided with a swing rod 50;

[0054] A vibration sound-generating assembly 60 is provided at one end of the swing rod 50, and the vibration sound-generating assembly 60 includes: a connecting rod 61, fixedly connected to the bottom of one end of the swing rod 50; a threaded rod 62, fixedly connected to the top of the connecting rod 61; a threaded seat 63, fixedly connected to the bottom of one end of the swing rod 50, and threadedly connected to the top of the threaded rod 62; a spring 64, fixedly connected to the bottom end of the connecting rod 61; a sound-generating bell 65, fixedly connected to the bottom end of the spring 64; a pull rope 66, arranged inside the sound-generating bell 65; a metal ball 67, fixedly connected to the bottom end of the pull rope 66;

[0055] When conducting a hearing test, the swing rod 50 swings, causing the spring 64 at the bottom of the connecting rod 61 to drive the sounding bell 65 to swing, so that the metal ball 67 in the sounding bell 65 hits the sounding bell 65 under the action of the pull rope 66, thereby making a sound (according to the hearing test requirements, the sound level of the vibration sounding component 60 is between 0-25 decibels).

[0056] In some embodiments, the steering motor 20 is mounted to the top of the wall via a fixing bracket.

[0057] In some embodiments, the sounding bell 65 is a trumpet-shaped structure.

[0058] In some embodiments, the vibration sound-generating component 60 further includes: a metal plate 68 symmetrically arranged on the inner wall of the sound-generating bell 65 .

[0059] In some embodiments, a swing bar control assembly 70 is provided between the traverse assembly 30 and the swing bar 50, and the swing bar control assembly 70 includes: a swing motor 71, which is provided at the output end of the traverse assembly 30; a swing shaft 72, which is fixedly connected to the output shaft of the swing motor 71; a socket 73, which is fixedly connected to the top of one end of the swing bar 50 and connected to the bottom end of the swing shaft 72;

[0060] In this embodiment, when conducting a hearing test, the swing motor 71 can directly drive the swing arm 50 to rotate, so that the swing arm 50 can turn freely (achieving a steering angle of 0-360 degrees). Compared with the steering motor 20 (which directly drives the swing arm 50 to rotate at any angle), this steering method can more accurately control the steering angle and improve the test accuracy of the hearing test equipment. In addition, the swing motor 71 can also drive the vibration and sound-generating component 60 to swing back and forth (the swing motor 71 directly drives the swing arm 50 to rotate back and forth within an angle range of plus or minus 5 degrees), so that the vibration and sound-generating component 60 makes a sound. Since the swing arm control component 70 directly drives the swing arm 50 to swing, the vibration amplitude of the vibration and sound-generating component 60 can be increased, thereby increasing the size of the sound emitted by the vibration and sound-generating component 60, further increasing the test range of the equipment.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
