CT (computed tomography) examination bed

Abstract

The invention relates to a CT examination bed. The CT examination bed comprises a bed board, bed legs, a mattress and one or more lead rubber protective mats, wherein the edge of the bed board is protruded; the mattress is arranged on the bed board and forms a gap from the bottom of the bed board; the one or more lead rubber protective mats are integrally in a rectangular shape, the parts of the lead rubber protective mats, which penetrate through the gap between the bed board and the mattress, are arranged on the bed board, and the parts of the lead rubber protective mats, which are in contact with the edge of the bed board, are provided with sliders fixed onto sliding rails on the edge of the bed board; both ends of the lead rubber protective mats extend out of the bed board and are provided with mutually-matched lap joints and fixed into a whole through the lap joints. When applied to examining a patient, due to the fact that unexamined parts of the patient are encircled at 360 degrees from bottom to top by the lead rubber protective mats, the CT examination bed can effectively avoid 360-degree radiation during CT helical scanning; meanwhile, the CT examination bed is made of X-ray transparent materials and is an area without being protected by the lead rubber protective pad, thereby avoiding affecting CT examination on the examined parts of the patient.

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. 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 of patients (such as gonads and thyroid...

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.
