Description

A medical examination bed that prevents bed sheets from drifting

technical field

The invention relates to the field of medical diagnosis and treatment beds, in particular to a diagnosis and treatment bed using disposable paper sheets.

Background technique

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. In order to avoid infection to other patients, the bed sheets need to be replaced. If the bed sheets are changed frequently, it will bring huge workload and high cost to medical workers. Patent No.: 02271093.0, which discloses a medical treatment bed using disposable paper sheets. Its main function is to realize the automatic replacement of disposable sheets, which solves the problem of cumbersome sheet replacement and reduces the cost of use in hospitals. hospital use.

However, in the diagnosis and treatment bed using paper sheets in the prior art, when the sheets are replaced, the old sheets are rolled up by the active rollers arranged at both ends of the bed frame, and the passive rollers release the new sheets and spread them on the examination bed. There is a certain distance between the driving roller and the passive roller. In the process of bed sheet laying, due to the disturbance of human factors and other factors, the bed sheet is shifted during the recovery process, which will cause contact between the bed sheet and the mounting brackets on both sides of the examination bed, and paper jams will occur, which will also affect the stability of the examination bed. beautiful.

Contents of the invention

The present invention aims at the deficiencies of the prior art, and provides a simple medical examination bed for preventing the deviation of the bed sheet during operation, which has a simple structure and greatly increases the firmness of the bed body.

In order to achieve the purpose of the present invention, the following technical solutions are provided: a medical examination bed for preventing bed sheets from wandering, including a mobile support, a bed set on the support, and two ends of the bed are respectively the active roller end and the passive roller end. It is characterized in that the end of the driving roller includes left and right support plates symmetrically arranged on both sides of the bed, a driving roller is arranged between the left and right support plates, and a correction roller is arranged above the driving roller, and the right end of the correction roller is plugged into the corresponding hole opened on the right support plate Inside, it is fixed by screws, and the left end is inserted into the left support plate corresponding to the strip chute, the center of the strip chute is facing the hole of the right support plate, and the inner sides of the left and right support plates above the correction roller are arranged symmetrically There is a deviation correcting rod, one end of the deviation correcting rod is fixedly connected to the left and right support plates, and the other end is fixedly connected to the side of the bed end, and the deviation correcting rod is inclined downward by 15 degrees from the left and right support plates to the side of the bed end, Make the left and right support plates, two deviation correction gear rods and the side of the end of the bed enough to form two triangular support structures.

Preferably, the upper surface of the deviation-correcting rod is provided with textured convex strips.

Preferably, the driving roller is covered with a wear-resistant sleeve.

Beneficial effects of the present invention: the present invention is that when the bed sheet passes the deviation correction lever during operation, the bed sheet will not tilt to both sides under the action of the extrusion force because the bed sheet is in contact with the deviation correction lever and receives the extrusion force toward the center of the bed. In this way, the running direction of the bed sheet is guaranteed; secondly, the inspection bed is equipped with a second deviation correction process, and the inspection bed is also equipped with a deviation correction roller, which can effectively adjust the manufacturing error of the bed itself and realize the correct running track of the bed sheet. The dual design of the examination bed effectively ensures that the bed sheet will be deviated during use, prevents paper jams caused by the deviation of the bed sheet, and also ensures the beauty of the examination bed during use.
