Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a hearing test device. Background Art

[0002] The purpose of hearing test is to determine the hearing loss of the subject at various relevant frequencies, and to express the test results on a coordinate graph with frequency as the variable. The hearing loss decibels of each frequency are connected into a line to form an audiogram. The audiogram can reflect the soundness of the subject's hearing. Therefore, hearing measurement can be used as supporting material for noise environmental pollution and medical diagnosis. However, we have found in real life that when the existing hearing test device performs a monophonic test on the patient's two ear canals, it is necessary to replace the left and right earphones to achieve the purpose of replacing the required test ear canal. However, this method may cause the patient's other ear canal to be exposed, so that the patient is affected by environmental factors, resulting in inaccurate test results. For this reason, we propose a hearing test device. Summary of the invention

[0043] The positioning member 7 includes a threaded groove 71 provided at both ends of the earphone body 1, a threaded rod 72 is provided at both ends of the earphone body 1, and the threaded rod 72 is threadedly connected to the earphone body 1 through the threaded groove 71, a positioning handle 73 is provided on the top of the threaded rod 72, and a positioning plate 74 is provided at the bottom of the threaded rod 72. A positioning groove 75 used in conjunction with two balls 2 is provided at the bottom of the positioning plate 74. When the balls 2 need to be rolled, the positioning handle 73 is rotated to rotate the threaded rod 72 at the bottom of the positioning handle 73 in the threaded groove 71 in the earphone body 1, and the threaded rod 72 moves upward. When the threaded rod 72 moves upward, the positioning plate 74 provided at the bottom of the threaded rod 72 will move upward with the threaded rod 72. When the threaded rod 72 drives the positioning plate 74 to move upward, the positioning groove 75 at the bottom of the positioning plate 74 will be out of control of the balls 2, so that the balls 2 can roll in the groove 81. Its function is to control the movement state or fixed state of the balls 2 according to the needs of patients and medical staff, thereby achieving the function of controlling the audio channel playback of the earphone body 1.

[0044] The trigger member 8 includes grooves 81 respectively provided at both ends of the earphone body 1, and the two balls 2 are arranged in the corresponding grooves 81, and the two balls 2 are movably connected to the adjacent grooves 81. The earphone body 1 is provided with a first wire 82 at both ends, and one end of the two first wires 82 is electrically connected to the controller 12, and the other end thereof is electrically connected to the earphone body 1.

When the patient wears the earphone body 1, in the initial state of the earphone body 1, the ball 2 inside it has been restricted by the positioning plate 74. At this time, the first wire 82 is the neutral wire, and the second wire 83 and the third wire 84 are the live wires. When the medical staff turns on the controller 12, the second wire 83 and the third wire 84 are the live wires. The wire 83 will conduct electricity to the third wire 84 through the conductive plate 85, so that the first wire 82 cooperates with the second wire 83, the conductive plate 85 and the third wire 84 to power the earphone body 1, so that both ends of the earphone body 1 can broadcast audio. When the ball 2 can roll in the groove 81, the patient tilts his head to the left or right, and the ball 2 in the opposite direction of the patient's head tilt begins to move. The ball 2 will squeeze the conductive plate 85 when moving in the groove 81. When the conductive plate 85 is squeezed by the ball 2, the conductive plate 85 will slide in the earphone body 1, so that the conductive plate 85 is separated from the second wire 83 and the third wire 84. The power-off slot 86 is located between the second wire 83 and the third wire 84, thereby disconnecting the power between the second wire 83 and the third wire 84, so that the patient can only hear the audio playing in the direction of his tilted head, thereby achieving the purpose of testing the patient's single ear canal. When the patient's head returns to an upright state, the ball 2 is released from the pressure on the conductive plate 85, and the energized spring 87 arranged at one end of the conductive plate 85 controls the conductive plate 85 to reset, and then the second wire 83 and the third wire 84 are energized, so that audio can be played at both ends of the earphone body 1. Its function is to be able to perform a hearing test on any ear canal of the patient.

[0045] The audio speaker component 5 includes an external speaker 9 respectively arranged at both ends of the earphone body 1, which is used to play audio externally and test the patient's hearing when playing audio externally.

The two wires One end of wire 104 away from the two external players 9 is arranged in the adjacent first control groove 101. When the patient needs to test the external hearing, he / she first tilts his / her head back. When the patient tilts his / her head back, the ball 2 will roll from the groove 81 to the first control groove 101. At this time, wire 1 102 and wire 3 104 are live wires, and wire 2 103 is the neutral wire. When the ball 2 rolls into the first control groove 101 and the ball 2 contacts wire 1 102 and wire 3 104, wire 1 102 and wire 3 104 conduct electricity through the ball 2, so that wire 2 103 cooperates with wire 1 102, ball 2 and wire 3 104 to power the corresponding external player 9, thereby making the two external players 9 play audio together. Its function is to test the patient's hearing ability to perceive external sounds.

Auxiliary frames 68 are arranged at both ends of the earphone body 1, and rotatable devices are arranged in the two auxiliary frames 68. An auxiliary shaft 69 is arranged, and an auxiliary torsion spring 610 is arranged on the outside of the two auxiliary shafts 69. One end of the two auxiliary torsion springs 610 is arranged on the corresponding auxiliary shaft 69, and the other end thereof is arranged on the corresponding auxiliary frame 68. A ratchet 611 used in conjunction with two ratchet wheels 67 is arranged on the outside of the two auxiliary shafts 69. A rotating handle 612 is arranged on the opposite ends of the two auxiliary shafts 69. A control torsion spring 613 is arranged on the outside of the two rotating shafts 63. When the patient puts on the earphone body 1, the auxiliary handle 66 is pulled, so that the auxiliary handle 66 drives the second rotating plate 62 to rotate on one side of the earphone body 1 through the rotating shaft 63. When the second rotating plate 62 moves under the action of the auxiliary handle 66, the second rotating plate 62 will drive the second shading cloth 6 5 moves, when the second shading cloth 65 is driven by the second rotating plate 62 for a distance, the second shading cloth 65 will drive the first rotating plate 61 to rotate on the side of the earphone body 1 through the rotating shaft 63 while moving, when the first rotating plate 61 rotates, the first shading cloth 64 will move along with the first rotating plate 61 under the action of the first rotating plate 61 until the first shading cloth 64 and the second shading cloth 65 cover the patient's face, when the first rotating plate 61 and the second rotating plate 62 rotate, the rotating shaft 63 will rotate together under the action of the first rotating plate 61 and the second rotating plate 62, at this time, the ratchet 67 set on the rotating shaft 63 will rotate along with the rotating shaft 63, and when the ratchet 67 rotates, it will lift the ratchet teeth 611 , so that the ratchet 611 cannot fix the rotating shaft 63 through the ratchet 67. When the rotating shaft 63 rotates, the control torsion springs 613 arranged at both ends thereof begin to accumulate force. When the user needs to retract the first shade cloth 64 and the second shade cloth 65, the user rotates the handle 612 to make the rotating handle 612 drive the auxiliary shaft 69 to rotate. At this time, the ratchet 67 that is out of the control of the ratchet 611 will rotate under the action of the control torsion spring 613, and the rotating shaft 63 arranged at the axis of the ratchet 67 will drive the first rotating plate 61 and the second rotating plate 62 to move closer to the earphone body 1 while rotating, thereby retracting the first shade cloth 64 and the second shade cloth 65. When the first shade cloth 64 and the second shade cloth 65 are retracted, the rotating handle 612 is released.The auxiliary torsion spring 610 disposed on the auxiliary shaft 69 controls the auxiliary shaft 69 to reset, so that the ratchet 611 controls the ratchet wheel 67 again.

[0049] When in use, first wear the earphone body 1. After the patient wears the earphone body 1, pull the auxiliary handle 66 so that the auxiliary handle 66 drives the second rotating plate 62 to rotate on the side of the earphone body 1 through the rotating shaft 63. When the second rotating plate 62 moves under the action of the auxiliary handle 66, the second rotating plate 62 will drive the second shading cloth 65 to move. After the second shading cloth 65 is driven by the second rotating plate 62 for a distance, the second shading cloth 65 will drive the first rotating plate 61 to rotate on the side of the earphone body 1 through the rotating shaft 63 while moving. When the first rotating plate 61 rotates, the first shading cloth 64 will move with the first rotating plate 61 under the action of the first rotating plate 61 until the first shading cloth 64 and the second shading cloth 65 cover the patient's face. When the first rotating plate 61 and the second rotating plate 62 rotate, the rotating shaft 63 will rotate together under the action of the first rotating plate 61 and the second rotating plate 62. At this time, the ratchet 67 set on the rotating shaft 63 will rotate together with the rotating shaft 63, and the ratchet 67 will lift the ratchet 611 while rotating, so that the ratchet 611 cannot fix the rotating shaft 63 through the ratchet 67. When the rotating shaft 63 rotates, the control torsion springs 613 set at both ends thereof begin to accumulate force. When the user needs to retract the first shade cloth 64 and the second shade cloth 65, the user rotates the handle 612 to make the rotating handle 612 drive the auxiliary shaft 69 to rotate. At this time, the ratchet 67 that is out of the control of the ratchet 611 will rotate under the action of the control torsion spring 613, and the control torsion spring 613 set at the rotating shaft 63 will rotate. The rotating shaft 63 at the axis of the ratchet 67 will drive the first rotating plate 61 and the second rotating plate 62 to move closer to the earphone body 1 while rotating, thereby retracting the first shading cloth 64 and the second shading cloth 65. When the first shading cloth 64 and the second shading cloth 65 are retracted, the rotating handle 612 is released, and the auxiliary torsion spring 610 set on the auxiliary shaft 69 will control the auxiliary shaft 69 to reset, so that the ratchet 611 controls the ratchet 67 again. When the patient wears the earphone body 1, the initial state of the earphone body 1 is that the ball 2 inside it has been restricted by the positioning plate 74. At this time, the first wire 82 is the neutral wire, and the second wire 83 and the third wire 84 are the live wires. When the medical staff turns on the controller 12, the second wire 83 passes through the conductive plate 85. The power is conducted to the third wire 84, so that the first wire 82 cooperates with the second wire 83, the conductive plate 85 and the third wire 84 to supply power to the earphone body 1, so that both ends of the earphone body 1 can broadcast audio. When the ball 2 needs to roll, the positioning handle 73 is rotated to rotate the threaded rod 72 at the bottom of the positioning handle 73 in the threaded groove 71 in the earphone body 1, and the threaded rod 72 moves upward. When the threaded rod 72 moves upward, the positioning plate 74 set at the bottom of the threaded rod 72 will move upward with the threaded rod 72. When the threaded rod 72 drives the positioning plate 74 to move upward, the positioning groove 75 at the bottom of the positioning plate 74 will be out of control of the ball 2, so that the ball 2 can roll in the groove 81. When the ball 2 can roll in the groove 81,When the patient tilts his head to the left or right, the ball 2 in the opposite direction of the patient's head tilt starts to move, and the ball 2 will squeeze the conductive plate 85 when moving in the groove 81. When the conductive plate 85 is squeezed by the ball 2, the conductive plate 85 will slide in the earphone body 1, so that the conductive plate 85 is separated from the second wire 83 and the third wire 84, so that the power-off groove 86 is located between the second wire 83 and the third wire 84, thereby disconnecting the power between the second wire 83 and the third wire 84, so that the patient can only hear the audio playback in the direction of his head tilt, thereby achieving the purpose of testing the patient's single ear canal. When the patient's head returns to an upright state, the ball 2 The conductive plate 85 is released from being squeezed, and the energized spring 87 arranged at one end of the conductive plate 85 controls the conductive plate 85 to reset, and the second wire 83 and the third wire 84 are energized, so that both ends of the earphone body 1 can play audio. When it is necessary to test the patient's hearing when playing loudspeakers, the first wire 82, the second wire 83 and the third wire 84 are powered off through the controller 12, so that both ends of the earphone body 1 cannot play audio. When it is necessary to test the patient's hearing when playing loudspeakers, the patient first raises his head. When the patient raises his head, the ball 2 rolls from the groove 81 to the first control groove 101. At this time, the wire 102 and the electric wire 104 are electrically connected. Wire three 104 is the live wire, wire two 103 is the neutral wire, when the ball 2 rolls into the first control slot 101, and the ball 2 contacts the wire one 102 and the wire three 104, the wire one 102 and the wire three 104 conduct electricity through the ball 2, so that the wire two 103 cooperates with the wire one 102, the ball 2 and the wire three 104 to supply power to the corresponding external player 9, thereby making the two external players 9 play audio together. When it is necessary to perform a single-ear-canal external sound test on the patient, the patient is required to lower his head and then turn his head. When the patient lowers his head and then turns his head, the ball 2 facing downward in the patient's ear canal starts to move. The ball 2 will pass through the groove 81 from the first control groove 101 and roll into the second control groove 111. When the ball 2 reaches the second control groove 111, the wire 1 112 and the wire 3 114 are live wires, and the wire 2 113 is neutral wire. When the ball 2 rolls into the second control groove 111 and the ball 2 contacts the wire 1 112 and the wire 3 114, the wire 1 112 and the wire 3 114 will be energized through the ball 2, so that the wire 2 113 cooperates with the wire 1 112, the ball 2 and the wire 3 114 to power the external player 9 facing downward, thereby achieving the test of the patient's single-ear-canal external hearing.

[0050] Example 2

[0051] See also Figure 15-17 , the present invention provides a technical solution:

[0052] Different from Example 1, this example provides another implementation of the positioning member:

[0053] The positioning member 7 includes a locking rod 76 slidably arranged at both ends of the earphone body 1, a locking handle 71377 is arranged on the top of the locking rod 76, a fixing plate 78 is arranged at the bottom of the locking rod 76, and a fixing groove 79 used in conjunction with the two balls 2 is provided at the bottom of the fixing plate 78, and a placement groove 710 is provided at both ends of the earphone body 1, and locking balls 711 are slidably arranged in the two placement grooves 710, and a plurality of locking grooves 712 used in conjunction with the two locking balls 711 are provided on the two locking rods 76, and a locking spring is arranged on the side of the locking ball 711 away from the locking rod 76, and the end of the locking spring away from the locking ball 711 is arranged in the placement groove 710. When it is necessary to roll the ball 2, the locking handle 71377 is pulled upwards to lock the locking handle When the locking rod 76 moves upward, the fixing plate 78 at the bottom thereof will move upward along with the locking rod 76, thereby releasing the restriction on the ball 2 by the fixing groove 79 at the bottom of the fixing plate 78. When the locking rod 76 moves upward, the locking rod 76 will squeeze the locking ball 711 and squeeze the locking ball 711 into the placement groove 710, and then continue to pull the locking rod 76 so that the next locking groove 712 on the locking rod 76 is aligned with the locking ball 711. At this time, the locking paralysis union on one side of the locking ball 711 will control the locking ball 711 to be stuck in the adjacent locking groove 712 again, thereby fixing the position of the locking rod 76, and then releasing the fixing of the ball 2 by the fixing plate 78 at the bottom of the locking rod 76.
