DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] The utility model provides Figure 1-5 The head fixing device for oral care shown in the figure comprises a base plate 1, a head fixing groove 4 and a neck support plate 2. The base plate 1 and the neck support plate 2 are connected by a rotating joint 3. The head fixing groove 4 is arranged on the upper surface of the base plate 1. A connecting ring 22 is fixedly arranged on the front side of the head fixing groove 4. A fixing belt 23 is arranged on the connecting ring 22. The function of the fixing belt 23 is to fix the mandible. A cushion layer 41 is arranged in the head fixing groove 4. A ventilation hole 5 penetrating the head fixing groove 4, the cushion layer 41 and the base plate 1 is arranged in the middle of the head fixing groove 4. The cavity between the cushion layer 41 and the head fixing groove 4 constitutes an interlayer 42, and the interlayer 42 is connected to the ventilation hole 5. A plurality of spring blocks are arranged in the interlayer 42. The spring blocks are distributed around the ventilation hole 5 and in a circular array in the head fixing groove 4.

[0025] See attached Figure 2 The spring block includes an outer frame and a first spring 9 arranged inside the outer frame. The outer frame is composed of an upper plate 6, a lower plate 7 and a flexible side plate 8. The lower plate 7 is fixed to the inner surface of the head fixing groove 4. The upper plate 6 is connected to the cushion layer 41. The first spring 9 is fixed between the upper plate 6 and the lower plate 7. The bottom surface of the upper plate 6 is connected to the fixing rod 10. The bottom of the fixing rod 10 is provided with a first sawtooth block 11. The inner surface of the flexible side plate 8 is fixed with a spring rod 12, and the spring rod 12 is connected to the folding rod 13. See attached Figure 4 The folding rod 13 includes a vertical rod 17 and an inclined rod 15. The upper end of the vertical rod 17 is provided with a second sawtooth block 14. The first sawtooth block 11 and the second sawtooth block 14 are axially arranged and the sawtooth tips of the two sawtooth blocks are staggered. The shaft of the inclined rod 15 is provided with a limit block 16. The upper surface of the limit block 16 is arc-shaped and the lower surface is a horizontal plane.

[0026] See attached Figure 3The spring rod 12 includes a disc 18 fixed to the folding rod 13, a steel wire 19 with one end fixed to the circumference of the disc 18, a limiting disc 20, and a second spring 21 between the flexible side plate 8 and the limiting disc 20. The circumference of the disc 18 is provided with a limiting groove matched with the steel wire 19, one end of the steel wire 19 is fixed in the limiting groove, and the other end passes through the flexible side plate 8 and is fixedly connected to the limiting disc 20.

[0027] See attached Figure 5 The folding rod 13 is originally located on one side of the first spring 9 . When the first serrated block 11 is pressed downward, the folding rod 13 rotates and moves with the limiting block 16 to face the first spring 9 .

[0028] The lower plate 7 is fixed on the inner surface of the head fixing groove 4. When the spring block is subjected to the head pressure, the first spring 9 contracts, the upper plate 6 moves downward, the fixing rod 10 on the bottom of the upper plate 6 moves downward, and the first sawtooth block 11 contacts the second sawtooth block 14. Since the saw teeth of the first sawtooth block 11 and the saw teeth of the second sawtooth block 14 are arranged in an interlaced manner, the saw teeth of the first sawtooth block 11 contact the saw teeth of the second sawtooth block 14 downward, causing the second sawtooth block 14 to rotate, thereby driving the folding rod 13 to rotate from one side of the first spring to the first spring. The limit block 16 is located in the axial gap of the first spring 9, and the first spring 9 is limited and stuck under the action of the limit block 16. The disc 18 fixed to the folding rod 13 rotates with the folding rod, pulling the wire rope 19 to contract the second spring 21. When the spring block is not subjected to pressure, the upper plate 6 moves upward, the first sawtooth block 11 is away from the second sawtooth block 14, and the second spring 21 recovers, pulling the folding rod 13 back to its original position.

[0029] The rotating joint 3 can adjust the relative position of the base plate 1 and the neck support plate 2 to better fit the patient's body shape.

[0030] A cushion layer 41 is arranged in the head fixing groove 4, and the cavity between the cushion layer 41 and the head fixing groove 4 constitutes an interlayer 42. A ventilation hole 5 penetrating the head fixing groove 4, the cushion layer 41 and the bottom plate 1 is arranged in the middle of the head fixing groove 4. The outer edge of the cushion layer 41 is connected to the outer edge of the head fixing groove 4, and spring blocks are arranged around the ventilation hole 5 to support the cushion layer 41. The interlayer 42 is connected to the ventilation hole 5 for air exchange to prevent the patient from feeling stuffy due to long-term contact of the head.

[0031] A plurality of spring blocks are arranged in the interlayer 42, and the spring blocks are distributed around the ventilation holes 5 and in a circular array in the head fixing groove 4. When the spring blocks are subjected to head pressure, the first spring 9 contracts downward, and the upper surface of the limit block 16 is arc-shaped, and the lower surface is a horizontal surface. The limit block 16 moves with the folding rod 13 to clamp the first spring 9. The first spring 9 can contract downward, but cannot be retracted due to the effect of the horizontal surface of the lower surface of the limit block 16. The spring blocks make the patient feel soft, fit and supportive on the head, which improves the patient's comfort and allows the patient's head to cooperate with medical staff to adjust the position and move slightly.
