Head fixer for cerebral angiography

Abstract

The invention discloses a head fixer for cerebral angiography, relates to the field of medical auxiliary instruments, and solves a problem of low comfort of a head fixer in the prior art. The head fixer comprises a mounting plate, wherein an overhead fixing assembly and a chin fixing assembly are fixedly connected on the mounting plate, the chin fixing assembly is slidably connected with the mounting plate through a sliding seat, the sliding seat is hinged with the chin fixing assembly, the overhead fixing assembly and the chin fixing assembly are both provided with an anti-hurting assembly for preventing a patient from being uncomfortable, and a buffer pad is further arranged on the mounting plate. According to the head fixer, the overhead fixing assembly can be deformed according to a head curve, the chin fixing assembly can fit the chin, and a head part is fixed through the overhead fixing assembly and the chin fixing assembly, and the anti-hurting assembly is arranged on the overhead fixing assembly and the chin fixing assembly to reduce the discomfort of the head part of a human body. Compared with the prior art, the head fixer has more secure fixing and higher comfort, and issuitable for popularization and use.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a head fixer for cerebral angiography. Background technique [0002] At present, cerebrovascular patients need to be treated with head contrast irradiation. When the patient is lying on the contrast table, the body and head need to be fixed, but most of the patients with cerebrovascular disease are the elderly. During radiography, the head may shake due to tension or physical shaking, resulting in blurred images. [0003] Chinese Patent Publication No. "CN204233147U" discloses a head radiography fixation device for cerebrovascular patients, including a mounting plate, an inflatable air bag and a head fixer; the head fixer includes a slider, a support rod, a sleeve , a push-pull rod, a fixed airbag and a hose; the mounting plate is provided with an embedded circular track, the slider is embedded in the circular track and can slide in the circular track, and the support ...

AI Technical Summary

Problems solved by technology

The utility model adopts the annular track adapted to the shape of the patient's head to cooperate with the head holder, and the positions of the four head holders can be adjusted through the sliding of the slider to adapt to patients with different body types, and can be selectively adjusted The number of head immobilizers can be fixed at least 2 or three or four, so as to prevent the patient from shaking, and the support rod can be rotated so that the fixed airbag in the head immobilizer is always facing the patient The head; however, the device uses a fixed block to fix the head. Since the curve of the human head is an atypical curve, there is a foreign body sensation when the fixed block is fixed, which makes the patient feel more uncomfortable when the device is fixed. Therefore, We present another head immobilizer for cerebral angiography
