Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3, the present utility model provides a technical solution: a head fixing device, including a bed body 1, a headrest area 2 and a pillow pad 3. The headrest area 2 is located at one end edge of the bed body 1. A pillow pad 3 is built in the central groove of the headrest area 2. Two parallel slide rails 4 are provided on the headrest area 2. A side plate base 6 is slidably installed on each slide rail 4 through a slider 5. A runner mounting seat 7 is fixedly installed on the outer side of the side plate base 6. A runner 8 is rotatably installed inside the runner mounting seat 7. An arc-shaped limiting back plate 9 is installed between the two runner mounting seats 7. The left and right ends of the arc-shaped limiting back plate 9 are respectively fixedly connected to the outer edge surfaces of the left and right runner mounting seats 7. A rotating arc plate 10 is arranged inside the arc-shaped limiting back plate 9. The left and right ends of the rotating arc plate 10 are respectively fixedly connected to the left and right runners 8. A rubber pressing plate 12 is installed at the center of the rotating arc plate 10 through a rotating screw 11;

[0017] An ear pad mounting plate 14 is fixedly installed on the inner side surface of the side plate base 6 through a fixing rod 13. A receiving groove is provided on the surface of the ear pad mounting plate 14. An arc-shaped rubber ear pad 16 is rotatably connected to the edge of the ear pad mounting plate 14 through a hinge shaft 15, and the arc-shaped rubber ear pad 16 is located in the receiving groove on the surface of the ear pad mounting plate 14.

[0018] There is a gap between the runner 8 and the side plate base 6. The rotating arc plate 10 adjusts the tilt angle inside the arc-shaped limiting back plate 9 through the runner 8. The ear pad mounting plate 14 is located inside the runner 8, and there is a gap between the ear pad mounting plate 14 and the runner 8 to prevent the side plate base 6 and the ear pad mounting plate 14 from hindering the rotational movement of the runner 8 when the rotating arc plate 10 rotates together with the runner 8.

[0019] The rubber pressing plate 12 is rotatably connected to the rotating screw 11. The height of the rubber pressing plate 12 is adjusted up and down through the rotating screw 11. By rotating the rotating screw 11, the rubber pressing plate 12 presses on the patient's forehead or scalp to fix the head.

[0020] Working principle:

[0021] In this device, the patient lies on the bed body 1, and the patient's head is placed on the pillow pad 3 in the central groove of the headrest area 2. The medical staff manually push the side base 6. Under the action of the slider 5, the arc-shaped limiting back plate 9 is moved closer to the patient's head. Then the medical staff manually pinch the rotating arc plate 10 and rotate the rotating arc plate 10 upward from the inside of the arc-shaped limiting back plate 9 so that the rotating arc plate 10 is located above the patient's head, and the rubber pressing plate 12 is located directly above the patient's forehead. By manually rotating the rotating screw 11, the rubber pressing plate 12 moves downward to stick to the patient's forehead;

[0022] Its rotating arc plate 10 is located inside the arc-shaped limit back plate 9 and can be rotated by the rotating wheel 8 to adjust the tilt angle, so that the rubber pressing plate 12 can be attached to the area range from the patient's forehead to the center of the top of the head.

[0023] On the inner side of its side plate base 6, an ear pad mounting plate 14 is fixedly installed through a fixing rod 13. The arc-shaped rubber ear pads 16 at the surface grooves of the ear pad mounting plate 14 are attached to the ears on both sides of the patient's head, avoiding discomfort caused by contact between the ears and the surface plane of the rotating wheel 8 when fixing the head. The arc-shaped rubber ear pads 16 at the surface grooves of the ear pad mounting plate 14 can be rotated through a hinge shaft 15, and the arc-shaped rubber ear pads 16 can be manually pulled outwards to facilitate cleaning of the arc-shaped rubber ear pads 16, so that the arc-shaped rubber ear pads 16 can be attached to the ears again when other patients lie on the bed body 1 subsequently.

[0024] The arc-shaped rubber ear pads 16 at the surface grooves of the ear pad mounting plate 14 also play a role in clamping both sides of the head to a certain extent.

[0025] In this device, the rotating arc plate 10 is rotatably installed inside the arc-shaped limit back plate 9 through the rotating wheel 8. Therefore, after the patient lies on the bed body 1 for diagnosis and treatment and finishes, Fang Baini pulls the rotating arc plate 10 upwards and then conducts cleaning and disinfection treatment on the rubber pressing plate 12.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
