Description

Inflatable headrest Technical Field The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to an inflatable headrest. Background In clinical surgery, the posture of the patient needs to be fixed by various supporting tools, wherein the posture of the head of the patient needs to be fixed by a headrest. The headrest is used for raising the head of a patient, so that the patient can take a natural lying posture, and meanwhile, the patient can be prevented from moving or shaking in the operation process. On one hand, the existing headrest for clinical operation is of a circular ring type structure, and is made of polymer gel materials, so that the problems of high cost, easiness in breakage and difficulty in cleaning exist, and glue leakage can occur after the headrest is broken, so that the operation environment can be possibly polluted. On the other hand, because the structure and the size of the headrest are fixed and cannot be adjusted, the applicability of the headrest is poor, and the supporting effect provided for patients with different body types is unstable. In view of the above, the present utility model proposes an inflatable headrest. Disclosure of utility model The present utility model has been made to solve the above-mentioned problems, and an object of the present utility model is to provide an inflatable headrest. The utility model realizes the above purpose through the following technical scheme: The utility model provides an inflatable headrest, which comprises a headrest cushion, wherein a penetrating groove is formed in the center of the headrest cushion, the groove is of a truncated cone-shaped structure with a wide upper part and a narrow lower part, the edge of the groove is in smooth transition, a plurality of air cavities are formed in the headrest cushion, the adjacent air cavities are communicated with each other, and a self-sealing type air port assembly is communicated with the headrest cushion. As a further optimization scheme of the utility model, the headrest cushion comprises a headrest portion and a neck support portion, the upper surface of the neck support portion is of an arched structure, and the topmost end of the arched structure is in smooth transition with the headrest portion. As a further optimization scheme of the utility model, the air cavities are of annular structures, all the air cavities are distributed from inside to outside, and the sizes of the air cavities are gradually increased from inside to outside. As a further refinement of the utility model, the air port assembly is located on the outside face of the headrest. As a further optimization scheme of the utility model, the air port assembly comprises a fixed air pipe communicated with the air cavity, an elastic sealing piece arranged in the fixed air pipe and a movable air pipe elastically and slidably connected with the fixed air pipe through a spring, wherein one end of the movable air pipe is positioned in the fixed air pipe. As a further optimization scheme of the utility model, the elastic sealing piece comprises a plurality of elastic sealing pieces which are distributed in a space spiral manner, the elastic sealing pieces are in a fan-shaped structure, the outer cambered surfaces of the elastic sealing pieces are fixedly connected to the fixed air pipe, and the inner edge parts of the adjacent elastic sealing pieces are stacked layer by layer. As a further optimization scheme of the utility model, a through hole with an annular structure is arranged between the adjacent air cavities in the headrest cushion. As a further optimization scheme of the utility model, the bottom of the headrest cushion is provided with an anti-slip cushion. The utility model has the beneficial effects that: According to the inflatable headrest provided by the utility model, the central groove with the wide upper part and the narrow lower part is arranged, so that the head of a patient can be attached to the headrest in a large area, the supporting stability and the comfort level are improved, the pressure born by the headrest can be dispersed, the plurality of air cavities for balancing the internal air pressure are arranged in the headrest, the probability that the headrest is damaged due to overlarge local pressure can be effectively reduced, and the service life of the headrest is prolonged. Through the cooperation of the headrest cushion, the air cavity and the air port component, the size of the headrest cushion can be adjusted by adjusting the inflation and deflation of the headrest cushion, so that the headrest can be suitable for patients with various body types. The inflatable headrest can be brushed integrally, so that daily maintenance and management are convenient.
