Abstract

The invention discloses a head traction device, which comprises a helmet body, wherein the front part of the helmet body is provided with an opening; an upper front positioning air bag is arranged at the front part inside the helmet body; an upper back positioning air bag and a lower back positioning air bag are arranged at the back part inside the helmet body; the upper front positioning air bag and the upper back positioning air bag are positioned above the opening; the lower back positioning air bag is near the bottom of the helmet body; each of the upper front positioning air bag, the upper back positioning air bag and the lower back positioning air bag comprises a positioning seat and an air bag body fixed with the positioning seat; a cavity communicating with the air bag body and a piston sliding in the cavity are arranged in each positioning seat; the lower end of each positioning seat is provided with a rotating block linked with the piston; when the rotating block rotates towards the positioning seat, the piston is driven to extract air from the air bag body; shoulder supporters are arranged at the two sides outside the helmet body; and support blocks capable of being linked with the shoulder supporters are arranged at the two sides inside the helmet body. The invention aims at providing the head traction device capable of providing stable support and avoiding the injury on a patient.

Description

technical field [0001] The invention belongs to the field of cranial traction, in particular to a cranial traction device. Background technique [0002] At present, in cervical spine surgery, the usual treatment methods for trauma such as cervical spine fractures and dislocations are: conservative treatment, traction immobilization or surgical treatment, and traction immobilization is also required before the operation. The traditional traction treatment method is to adopt a cloth cover to hang the lower jaw of the patient, and to carry out traction upwards, as the Chinese patent announcement number: CN104207871A, which discloses a cervical vertebra tractor. It belongs to the technical field of new medical materials. The cervical vertebra tractor comprises an air bag for supporting the head or pulling the cervical spine after being inflated, an inflatable ball for inflating the air bag, an air guide tube connecting the air bag and the inflatable ball, and a needle valve arr...
