A kind of scoop stretcher that medical field uses
Technical field
The invention belongs to stretcher technical field more particularly to a kind of scoop stretchers that medical field uses.
Background technique
With the development of science and technology, the prosperity of people's lives increasingly, at the same Medical Devices also constantly into
Step, Medical Devices find its insufficient and disadvantage during use, then make improvements and innovate, more meet people
Demand, it is quick that it is more convenient to use.
Stretcher is one of equipment common in Medical Devices, when patient can not voluntarily walk, with internal severely injured, fracture
When etc. strenuous vibration or activity is unable to, it is often necessary to move patient using stretcher, scoop stretcher is by two pieces of left and right shovel
Piece composition.It is different from general stretcher, it is lifted after two pieces of shovel pieces being inserted into patient body respectively in the following, fastening.Most
The reduction of the limits secondary injury caused by patient in the handling process.But general scoop stretcher is due to being by left and right two panels
Shovel piece composition, in use, the pressure that two panels shovel piece can bear is smaller, and the frame of scoop stretcher generally folds
Type is more easily damaged, once secondary injury may be caused to patient by being destroyed;So designing a kind of more solid shovel load
Frame is necessary.
The present invention design a kind of scoop stretcher that medical field uses solve the problems, such as it is as above.
