Scanning bed

Abstract

The invention provides a scanning bed. The scanning bed comprises a machine body, a control device and a driving mechanism and further comprises a bed board and a bed cover plate arranged on the machine body. The driving mechanism is used for driving the bed board to move on the bed cover plate; the scanning bed further comprises a detecting device connected with the control device, and the detecting device is used for detecting the distance between one fixed position of the bed board and one fixed position of the bed cover plate; when the detecting device detects that the distance between the fixed position of the bed board and the fixed position of the bed cover plate reaches preset distance, the control device controls the driving mechanism to stop so as to make the front end of the bed board protrude out of the front end of the bed cover plate. In the scanning bed, the detecting device is arranged to detect the distance between the bed board and the bed cover plate, the control device controls the driving mechanism to stop according to the detected distance, and therefore obstacles are prevented from entering the machine body and influencing motion of the bed board.

Description

technical field [0001] The present application relates to the field of medical equipment, in particular to a scanning bed. Background technique [0002] In the prior art, the scanning bed of the medical equipment is a tool for carrying the examinee when completing the scanning task. The patient can lie on the bed of the scanning bed, and the bed can drive the patient to move forward and backward relative to the body. In the use of scanning beds in some hospitals, for the convenience of cleaning, disposable sheets will be placed on the bed board. This kind of disposable bed sheet is generally made of non-woven fabric or plastic material, which is relatively light and thin, and will move with the patient's getting on and off the bed, the movement of the patient on the bed board, or the movement of the bed board itself, making it easier for the disposable bed sheet to be twisted into the scanning bed . There are two ways for disposable bed sheets to enter the scanning bed: on...

Problems solved by technology

This kind of disposable bed sheet is generally made of non-woven fabric or plastic material, which is relatively light and thin, and will move with the patient's getting on and off the bed, the movement of the patient on the bed board, or the movement of the bed board itself, making it easier for the disposable bed sheet to be twisted into the scanning bed

There are two ways for disposable bed sheets to enter the scanning bed: one is to enter from the front of the bed, and the other is to enter from the back of the bed. When the disposable bed sheet is twisted into the scanning bed, it will form a blockage and affect the movement of the bed board.
