Description

Movable sickbed

Technical Field

Background

At present, hospital beds are generally divided into two types, one type is an ordinary ward used in the ward, the ordinary ward is generally rarely moved, the ordinary ward is generally wider and heavier in design, and multiple persons are required to transfer the sickbeds together in special cases, and the ordinary ward cannot pass through the sickbeds due to the limited width of part of ward doors; the other is an examination bed of an auxiliary diagnosis department, which is generally designed to be narrower, and the patient with excessive weight is at risk of falling down. The two traditional sickbeds have no assistance during transfer, and a great deal of physical strength and energy of medical staff are consumed, so that medical resources are wasted. In addition, in the transfer process, in order to ensure the safety of the patient, various monitoring devices including an electrocardiograph are required to be carried, so that the nurse is often required to periodically visit a ward and make relevant records of the patient in order to grasp the vital sign change of the patient when working in a disease area.

And this method has the following problems: the auxiliary personnel are more needed; the patient is easily damaged secondarily due to improper handling. If a patient with fracture is just treated with a major operation, the patient can not be dragged, turned over, twisted and the like when being carried, and the patient is extremely easy to be secondarily injured by carelessness; the traditional method has the defects of great handling attention, complex process operation, trained and combined with mercy for operators, such as poor coordination, and great possibility of causing strain or sprain of the body of the patient.
