Technical Field

[0001] The utility model relates to the technical field of detection of cranial nerve motor dysfunction, in particular to a detection system for cranial nerve motor dysfunction. Background Technique

[0069] The position where the top clamping member 2300 contacts the tester is the top of the tester's head, and the position where the side clamping member 2400 contacts the tester is the rear part of the tester's ears, effectively avoiding the top clamping member 2300 and the side clamping member 2400 from appearing in the captured image when the high-definition camera takes a picture, which affects the subsequent imaging.

[0070] In an alternative embodiment, the sliding member 2200 includes a connecting main body 2210 and a slider main body 2220; the connecting main body 2210 is arranged on the slider main body 2220, and the connecting main body 2210 and the slider main body 2220 are an integrally formed structure.

By using the first transmission member 2500 to drive the rotation of the lead screw main body 2110, the overall lifting of the sliding member 2200 is realized.

[0074] Specifically, as Figure 4 shown, it should be noted that Figure 4 is a schematic diagram of removing the outer shell plate of the fixing main body 2100. The first transmission member 2500 includes a first handwheel 2510, a first transmission shaft 2520 and a reversing connector 2530; the first transmission shaft 2520 is arranged inside the fixing main body 2100, one end of the first transmission shaft 2520 extends out of the fixing main body 2100 and is connected to the first handwheel 2510, and the other end of the first transmission shaft 2520 is connected to the lead screw main body 2110 through the reversing connector 2530.

[0078] Specifically, as Figure 5 、 Figure 6As shown, in an alternative embodiment, the second transmission member 2600 includes a second handwheel 2610, a second transmission shaft 2620, and a transmission gear 2630. One end of the second transmission shaft 2620 is provided with the second handwheel 2610. An operator uses the second handwheel 2610 to drive the rotation of the second transmission shaft 2620.

The top clamping member 2300 is connected with a rack 2640, and the transmission gear 2630 is meshed with the rack 2640, so that when the second transmission shaft 2620 rotates along its own axis direction, it drives the top clamping member 2300 to move up and down.

[0079] In an alternative embodiment, the second transmission member 2600 further includes a housing main body 2650. The second transmission shaft 2620 is arranged inside the housing main body 2650, and one end of the second transmission shaft 2620 passes through the housing main body 2650 and is connected with the second handwheel 2610.

[0081] Specifically, a tension spring is arranged inside the connecting seat 2320. One end of the tension spring is fixed on the connecting seat 2320, and the other end of the tension spring is connected with the pressing plate main body 2310, so that the pressing plate main body 2310 has a downward movement tendency. After the tester stands up, the pressing plate main body 2310 rotates upward under the drive of the tester. When the tester leaves, the pressing plate main body 2310 resets under the action of the tension spring and returns to the horizontal position.

[0082] The facial nerve motor function detection fixing device provided by this embodiment can freely change the height positions of the top clamping member 2300 and the lateral clamping member 2400 according to the body type of the tester, meeting the needs of testers with different body types. Moreover, since the top clamping member 2300 has elastic potential energy, after the tester stands up, the top clamping member 2300 will not be damaged due to the sudden standing up of the tester.
