CT examination bed with extension-retraction protection hood

Abstract

The invention relates to a CT examination bed with an extension-retraction protection hood. The CT examination bed includes a bed board, bed legs and a mattress and further includes a plurality of lead rubber protection mats; the edge of the bed board of the CT examination bed protrudes, the mattress is laid on the bed board, and a gap exists between the mattress and the bottom of the bed board; the lead rubber protection mats are in long strip shapes and penetrate through the gap between the mattress and the bed board, part of the lead rubber protection mats are laid on the bed board, and part of the lead rubber protection mats extrude out of the bed board; two free ends of each lead rubber protection mat are provided with mutually matched lapping parts; scrolls are fixed to the two sidesof the bed board, and a plurality of protrusion parts are arranged on the scrolls; the two ends of each lead rubber protection mat are both provided with long lines, and the other ends of the long lines are twined on the protrusion parts on the scrolls. When the CT examination bed with the extension-retraction protection hood is used for examining a patient, the unexamined part of the patient issurrounded in 360 degrees by the lead rubber protection mats from bottom to top, and therefore irradiation of rays in 360 degrees can be effectively protected when CT helical scanning is carried out.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a CT examination bed with a retractable protective cover which can protect 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 pati...

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.
