Description

A quick rescue stretcher

technical field

The utility model belongs to the field of medical equipment and relates to a stretcher, in particular to a quick rescue stretcher.

Background technique

The stretcher that is used for rescue mainly comprises two kinds in the market at present: a kind of is simple and easy stretcher, and another kind is stretcher cart. The structure of the simple stretcher is simple, but all rescue work is completely dependent on the operation of the staff, which increases the labor intensity of the staff and reduces the efficiency of rescue. The stretcher trolley overcomes the shortcomings of a simple stretcher, but its complex structure, cumbersome operation, and large volume also make it subject to many restrictions in rescue work. Simultaneously, these two kinds of stretchers all need the staff to bend over to lift the wounded onto the stretcher during use, and the active role of the stretcher has not been brought into play at all. For some seriously wounded people who cannot be easily moved, large-scale movement will cause them additional injuries and threaten the lives of the wounded.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a quick rescue stretcher, the entire rescue process is completely played by the stretcher, and no staff need to bend down to lift the wounded.
