Diagnosis and treatment bed

Abstract

The invention discloses a diagnosis and treatment bed. The bed comprises a paper bed sheet output guide roller and a collection guide roller mounted at front and back ends of a bed frame; a deviation correction roller is mounted close to one end of the output guide roller or collection guide roller; and a driving mechanism is connected at the end part of the deviation correction roller for driving the deviation correction roller to move along the movement direction of the paper bed sheet to adjust the paper bed sheet running position, thereby ensuring orderly paving of paper bed sheet on a bed mattress. During bed sheet replacement, the paper bed sheet collection guide roller is started to roll up the used paper bed sheet, while the output guide roller is pulled to rotate and convey a new paper bed sheet to pave on the bed mattress. According to the invention, the manual movement of paving the paper bed sheet is avoided, the paper bed sheet is ensured to be rolled up on the collection guide roller orderly, seizure of collection guide roller due to paper deviation is avoided, and the stability of the bed sheet rolling up is guaranteed.

Description

technical field [0001] The invention relates to a medical diagnosis and treatment bed, in particular to a diagnosis and treatment bed using disposable paper sheets. Background technique [0002] When the hospital is diagnosing patients, the diagnosis and treatment beds used are usually ordinary beds. After a period of use, the bed sheets need to be replaced. Some patients have infectious bacteria. The bed sheets need to be replaced.

[0003] Chinese Patent No.: 02271093.0 Utility Model Patent, which discloses a medical diagnosis and treatment bed using disposable paper sheets. Active rollers and passive rollers are respectively installed at the front and rear ends of the bed frame. The dis...

AI Technical Summary

Problems solved by technology

[0004] In the prior art diagnosis and treatment bed using paper sheets, when the sheets are replaced, the old sheets are rolled up by the rotation of the active roller and the passive roller arranged at both ends of the bed frame, and the new sheets are covered on the mattress at the same time. The rollers are far away from each other. During use, it is found that when the paper sheets are pulled and run, the paper sheets often deviate from the position of the mattress, and cannot be laid on the mattress correctly. Manually move the bed sheet to make it lay flat and correct on the mattress, which brings a lot of trouble to the daily use of the hospital. Every time the bed sheet is changed, someone needs to move the bed sheet, which is extremely inconvenient to use. More importantly, , because the general hospital needs to use more paper sheets, it will need to roll a thicker sheet, due to the offset, it will cause the roll to be stuck in the middle, so that the operation of rolling the sheet cannot be completed
