Description

A new type of CT machine scanning examination bed

Technical field

The invention belongs to the technical field of medical devices, and particularly relates to a new type of CT machine scanning examination bed.

Background technique

An X-ray beam is used to scan a certain part of the human body at a certain thickness. When the X-rays are emitted to the human tissue, some of the rays are absorbed by the tissue, and some of the rays pass through the human body and are received by the detector to generate a signal. Because the density of various tissues in the human body is different and the penetration capabilities of X-rays are different, the rays received by the detector are different. The received differential ray signals are converted into digital information, which is processed by a computer and output to a display screen to display an image. This image is called a cross-sectional image. It is characterized by easy operation, fast scanning time, and clear images. It is painless for patients. It has high density and resolution. It can observe very small lesions in the human body and directly display organs and lesions that cannot be displayed by plain X-ray films. . When currently used, the patient lies on the bed of the CT machine, with his hands raised above his head and flat on both sides of his head. Some beds are equipped with foam pillows at the head, and the arms are placed on the foam pillows. superior. When scanning, it is necessary to inject contrast agent through a syringe at the same time to increase the scanning effect. An infusion is used, and the infusion tube separated from the syringe is connected to the patient's arm. Usually awake adult patients have self-control. The body will not shake, but when the patient suddenly moves due to convulsions or other personal reasons, the medical staff will be unable to quickly remove the needle for emergency treatment or even rescue, resulting in various dangers and various subsequent dangerous accidents. Therefore, During the entire process of patient scanning and before the patient leaves the bed, it is necessary to keep the position of the patient's arm unchanged so that the needle can be removed as quickly as possible and the patient's emergency situation can be dealt with as quickly as possible.

Contents of the invention

The present invention provides a new type of CT scanning examination bed. The technical problem to be solved is that during the CT scanning process, a patient suddenly twitches or moves, causing medical staff to be unable to quickly pull out the needle for rescue or treatment, thereby affecting the patient's health. Causing danger and subsequent dangerous accidents.

In order to solve the above technical problems, the present invention adopts the following technical solution: a new type of CT machine scanning examination bed, which includes a horizontally arranged scanning bed body.
