[0022] The adjustable chin fixation strap includes two straps 3, wherein a plurality of buckles 4 are installed at intervals on the inner side of one of the straps 3, and a positioning hole matched with the size of the buckle 4 is provided on the outer side of the other strap 3. Both the strap 3 and the buckle 4 are made of rubber, which is elastic and can be deformed. The distance between the two straps 3 can be adjusted through the plurality of positioning holes and the buckle 4, so that it can be used for patients with different head circumferences.

[0023] The adjustable headband includes a headband 2, which is made of rubber and can be deformed to fit the patient's head. An outer tube 12 is installed at both ends of the headband 2. A groove is provided at the bottom of the outer tube 12. An inner rod 13 is slidably connected inside the groove. Two adjustment plates 14 are slidably connected inside the inner rod 13. A limiting spring 15 is elastically connected between the two adjustment plates 14. The limiting spring 15 serves to limit the sliding distance of the two adjustment plates 14. A pressing block 16 is installed at the lower end of the side where the two adjustment plates 14 are away from each other. The lower end of the inner rod 13 is provided with a sliding hole that is slidably connected to the pressing block 16. The pressing block 16 extends out of the inner rod 13 through the sliding hole and is located on the outside of the outer cylinder 12. Pressing the pressing block 16 can realize the sliding of the adjustment plate 14. A positioning block 17 is installed on the upper end of the side of the adjustment plates 14 that are away from each other. The upper end of the inner rod 13 is provided with a through hole that is slidably connected to the positioning block 17. The outer side of the positioning block 17 is provided with teeth.

[0025] Working principle: After applying the dressing to the patient's ear, put the gasket 5 and the breathable net 6 into the through hole of the earmuff 1 in turn, and then stick the waterproof membrane 7 into the through hole, then separate the two straps 3, and then cover the earmuff 1 on the outside of the patient's ear, press the pressing blocks 16 on both sides, the pressing block 16 drives the adjustment plate 14 and the positioning block 17 to slide, the limit spring 15 is squeezed and compressed by the adjustment plate 14, and the teeth of the positioning block 17 are out of contact with the tooth grooves of the outer tube 12. At this time, the outer tube 12 can slide on the outside of the inner rod 13, and the outer tube 12 drives the headband 2 to slide to fit the patient's head, and then release the pressing block 16. The thrust of the limit spring 15 drives the adjustment plate 14, the pressing block 16 and the positioning block 17 to return to their original position. At this time, the teeth of the positioning block 17 are engaged with the tooth grooves of the outer tube 12 to fix the earmuff 1 on the outside of the patient's ear, and then fit the two straps 3 to the patient's lower jaw to make the head buckle 4 is inserted into the corresponding positioning hole on the other strap 3. When replacing the dressing, pinch the corresponding tear strip 8 to tear the waterproof film 7, take out the gasket 5 and the breathable mesh 6, replace the dressing through the through hole of the earmuff 1, put the new gasket 5 into the through hole, then put the breathable mesh 6, and then stick the waterproof film 7 into the through hole. When the patient only needs to bandage and fix one ear, pinch the earmuff 1 and the limiting piece 10 of the strap 3 at the corresponding end to make the limiting piece 10 on the top of the earmuff 1 detach from the adjusting buckle 11 at the bottom of the inner rod 13 at one end, and the limiting piece 10 on the strap 3 detaches from the adjusting buckle 11 at the bottom of the earmuff 1, and then pinch the limiting piece 10 on the strap 3 and insert it upward into the jack of the adjusting buckle 11 at the bottom of the inner rod 13. The limiting piece 10 will automatically unfold and be stuck in the limiting hole of the adjusting buckle 11 after being free from force, so as to realize the direct connection between the strap 3 and the inner rod 13 and increase the comfort of the patient.
