Fully-protective CT examination bed

Abstract

The invention relates to a fully-protective CT examination bed. The bed comprises a bed board, bed legs, a mattress and one or two lead rubber protection pads; the edges of the bed board protrude out,the mattress is laid on the bed board, and gaps exist between the mattress and the bottom of the bed board; the whole long-strip-shaped lead rubber protection pads penetrate through the gaps betweenthe bed board and the mattress, are partially laid on the bed board, and partially extend out of the bed board; brackets are fixedly arranged at the bottoms of the portions, laid on the bed board, ofthe lead rubber protection pads, the two ends of each bracket are fixed to a sliding rail arranged at the edges of the bed board, and the brackets are fixedly connected with retractable guide rods; the two ends of each lead rubber protection pad are provided with lap joint pieces matched with each other and fixed into an integrated part through the lap joint pieces. According to the CT examinationbed, when a patient is examined, since a non-examined part is surrounded by the lead rubber protection pads at 360 degrees from bottom to top, the 360-degree ray irradiation can be effectively protected during CT spiral scanning.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a CT examination bed capable of protecting CT examination patients and non-examined parts from damage by CT rays and capable of comprehensive protection. Background technique [0002] In recent years, the wide application of CT has brought great benefits to the clinical diagnosis of diseases, but we should not ignore the harm that radiation brings to people. X-rays can penetrate cells and damage DNA, causing irreparable lifelong damage to genetic molecules, and even inducing cell cancer. Irradiation of the inspection area is the price that must be paid for diagnosing diseases, while the irradiation of non-examination areas is worthless and harmful. [0003] At present, in the process of performing CT scans on patients, hospitals generally use lead rubber gonad protective aprons (square scarves), lead rubber neck sleeves, and lead rubber caps to protect non-examined parts...

AI Technical Summary

Problems solved by technology

[0004] Its disadvantage is that the existing radiation protection methods only pay attention to the situation that the patient receives X-ray irradiation in one direction

CT scans are generally spiral scans, and the CT tube surrounds the patient for 360° uninterrupted radiation output. The existing CT patient protection methods cannot achieve 360° no dead angle protection.
