Abstract
Description
Technical Field

[0002] The audiometer sends specific frequencies to the examinee through headphones and other devices, and the examinee sends signals by feeling the changes and stimulation of these frequencies, and the examinee's hearing can be known through the audibility curve.

However, existing medical staff can usually only gain relevant experience through practice, which is inefficient and cannot see a more comprehensive situation. In the usual simulation learning, only one student can use the existing audiometer, and other students learn to record.

In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be said that the internal connection of two components is connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The technical solution of the present invention is further explained below in conjunction with the accompanying drawings and embodiments.
[0026] like Figure 1-Figure 3 As shown, a simulation device for audiometer testing of the present invention comprises an audiometer host 1 and a human model 2 arranged on the audiometer host 1, and further comprises:
[0027] A control module, provided on the audiometer host 1, for inputting and adjusting the hearing test mode for the user;
[0028] The processing module is arranged in the audiometer host 1 and is electrically connected to the main control module and the connection module respectively, and is used to receive the signal of the control module and control the circuit of the connection module to be turned on and off according to the hearing test mode;
[0029] A connection module, extending from the audiometer host 1 and detachably connected to both sides of the human model 2, for controlling the on and off of the circuit according to the signal of the processing module;
[0030] The display modules are respectively arranged at two eye positions of the human body model 2 and respectively connected to the connection modules correspondingly, and are used to display whether a sound is heard or not according to the on-off status of the circuit of the connection module.
[0031] The present invention is applied to the detection process of learning the use of audiometer and simulating hearing test, and has better stability than directly testing with real people, and is suitable for students' transitional learning from written knowledge to clinical practice. The device can control the circuit on-off change of the connection module by the teacher inputting the hearing test mode on the control module, or according to the case situation stored and collected by the processing module, and the display module displays whether the sound is heard or not according to the change of the circuit on-off, so as to simulate the reaction of the subject under the corresponding situation, so that the student can observe the sound playing situation, that is, the display on the control module, and the display of whether the sound is heard on the display module, comprehensively learn and judge the simulation detection situation of the audiometer, and increase similar practical experience. Using the device for simulation learning does not require real people to test, nor does it need to use real audiometers, headphones and other high-cost and fine-made equipment. The device has a high simulation effect, replaces whether the sound is played with the circuit on-off to simulate the reaction of the subject with mechanical equipment, and has a high reference learning value.
[0032] In one embodiment, the connection module includes an extension wire 3 and an electromagnet 4 which are sequentially connected to the processing module. The extension wire 3 extends from the left and right sides of the audiometer host 1. The electromagnet 4 is provided with a connector 5. The two ear positions of the human model 2 are provided with a connector 6 which is adapted to the connector 5. The connector 6 is provided with a magnetic switch 61 which is adapted to the electromagnet 4. The magnetic switch 61 is used to control the display module to display whether the sound is heard or not by turning it on or off. The circuit on and off of the connection module mainly transmits information by the magnetic force change of the electromagnet 4. Through the cooperation of the connector 5 and the connector 6, it can simulate the subject wearing the headphones for detection. In practice, the user also needs to check that the subject wears the headphones correctly, that is, the connector 5 and the connector 6 cooperate correctly, so that the electromagnet 4 can correspond to the magnetic switch 61, so as to control the magnetism of the electromagnet 4 by using the on and off of the circuit, and then control the opening and closing of the magnetic switch 61. In this way, the circuit in the display module can control the display of "hearing sound" or "not hearing sound" by turning on and off the magnetic switch 61.
[0033] In one embodiment, the connector 5 is located outside the electromagnet 4 and is rotatably connected to the electromagnet 4. The outer edge of the connector 5 extends in the direction of the central axis, and two protrusions 51 are symmetrically arranged inward at the outer edge of the connector 5. The connecting portion 6 is protruded at the two ear positions of the human model 2. The magnetic switch 61 is located in the middle of the connecting portion 6. Two guide rails 62 that match the protrusions 51 are provided on the side of the connecting portion 6, and one end of the two guide rails 62 extends to the surface edge of the connecting portion 6 and is open. When the connector 5 is matched with the connecting portion 6, the protrusions 51 of the connector 5 need to be pressed down corresponding to the openings of the two guide rails 62, and then the connector 5 is rotated along the guide rails 62, so that the electromagnet 4 is close to the metal sheet of the magnetic switch 61 until they are close to each other. By connecting the electromagnet 4 circuit of the connecting module, it can be tested whether the display module, i.e., the display screen or indicator light at the eye position on the human model 2, reacts, thereby judging whether the connection is stable.
[0034] Furthermore, in order to ensure that the electromagnet 4 in the connecting member 5 can be in close contact with the metal sheet of the magnetic switch 61, an elastic member is provided on the electromagnet 4. In the natural state, the electromagnet 4 does not exceed the protrusion 51 of the connecting member 5; when the connecting member 5 is matched with the connecting portion 6, the elastic member makes the electromagnet 4 close to the metal sheet of the magnetic switch 61. The elastic member can be a component such as a compression spring, which is directly set at the bottom of the electromagnet 4 so that the electromagnet 4 has a certain activity space, or the electromagnet 4 can be fixed and covered with an iron sheet on the top. Similarly, when matched, the electromagnet 4 is in close contact with the iron sheet and then with the iron sheet of the magnetic switch 61. In this way, when the electromagnet 4 is energized and generates magnetic force, the iron sheet will be magnetized, thereby controlling the on and off of the magnetic switch 61. The magnetization reaction and process of the electromagnet 4, plus the reaction time of the display module, can just simulate the reaction time given by the left and right ears of the subject after hearing the sound.
[0035] In addition, the rear side of the audiometer host 1 is provided with a storage slot 7 for placing the extension cord 3, the electromagnet 4 and the connector 5, so that when the device is not in use, the extension cord 3, the electromagnet 4 and the connector 5 can be protected in the audiometer host 1, and it is not easy to cause damage to the connection module. A rotating member 11 is rotatably connected to the side of the audiometer host 1, and the extension cord 3 extends from the rotating member 11. The rotating member 11 is used to rotate the extension cord 3 and the electromagnet 4 between the storage slot 7 and the connection part 6. The rotating member 11 can be a switch component such as a knob. When the extension cord 3 is rotated to the rear side of the connection module to be stored, the knob is in a closed state, and the connection module is not controlled by the processing module. Therefore, the power supply can be disconnected, making the use of the electromagnet 4 safer. When in use, the rotating member 11 is rotated to the direction in which the extension cord 3 extends upward. At this time, the knob is turned on, and the connection module can communicate signals with the processing module.
[0036] In one embodiment, the upper side of the audiometer host 1 is a plane whose area is larger than the bottom area of the human body model 2. The human body model 2 is rotatably connected to the plane through a rotating mechanism 8. The rotating mechanism 8 allows the human body model 2 to rotate along the horizontal plane to adjust the facing angle. The human body model 2 is mainly installed with a connection module and a display module, which can be independent of the circuit or connected to the power supply in the audiometer host 1. The rotating mechanism 8 allows the human body model 2 to rotate 360° to facilitate simulation observation and explanation. The rotating mechanism 8 includes a connected motor and a rotating shaft. The motor is electrically connected to the processing module, that is, the rotation of the rotating shaft can send a signal to the control module to control the motor through the processing module. If the module in the human body model 2 needs to share a power supply with the audiometer host 1, the rotating shaft is a hollow structure, and the wires are connected from the middle, but the left and right rotation of the human body model 2 needs to be limited and cannot exceed one circle.
[0037] In addition, the front side of the audiometer host 1 is an inclined plane, and the control module and the connection module correspond to each other and are arranged on the inclined plane. The control module includes a button 9 and a display screen 10. The control module can also be set to two groups to control the left and right ears respectively, and can simulate the different hearing conditions of the left and right ears in actual situations and require different hearing test modes for further testing. The device can also be provided with earphones 12, which are electrically connected to the processing module. The earphones 12 are used to play sounds according to the hearing test mode. In this way, the device can also allow students to experience the hearing test mode as normal people, or use the processing module to simulate a subject with hearing impairment, so that students can experience the hearing test process of the subject.
