Description

A portable emergency stretcher

technical field

The invention relates to medical equipment, in particular to a portable emergency stretcher.

Background technique

In the emergency clinic, the stretcher, as an auxiliary device that must be used, has assumed an irreplaceable role. There are two types of existing stretchers: fixed type and foldable type. The structure of the fixed type is relatively simple. The parts are fixedly connected and can be used at any time. Emergency outpatient use; the foldable stretcher is small in size, takes up little space, and is easy to carry in the storage state. It is usually composed of retractable long rods on both sides and mesh. The two long poles can be joined together to reduce the space occupied. The existing folding stretcher has given up the use of the crossbar, that is, it is only composed of two telescopic long poles and mesh cloth. When the stretcher with this structure is in use, The mesh will bend downward under the action of its own weight and the weight of the patient's body, forcing the two long poles to approach each other, and the patient's body posture will be restrained under pressure, which is very unfavorable for normal diagnosis and treatment. In addition, the folding stretcher of this structure can only be used as a transfer tool for patients because of the lack of a stable plane support frame, and cannot be used as a workbench, let alone adjust the height from the ground.

Chinese patent announcement No. 205598111U discloses a portable emergency internal medicine folding stretcher, including a sleeve, a sleeve rod, a bending connecting rod, a handle, a cross bar and a mesh cloth, the sleeve pipe is connected with the sleeve rod and the bending connecting rod, and the outer wall There is a chute and a first positioning button on the top, and the end of the sleeve rod extending into the sleeve is provided with a resistance block, which is slid and positioned in the sleeve through the first positioning button, the cross bar is hinged with the sleeve, and one end of the bent connecting rod extends Insert the casing, the other end is connected with the handle, the casing, the casing rod, and the cross bar form a rectangular frame, the mesh is fixed in the rectangular frame, the end of the casing is provided with a bending foot, and the bending foot is provided with a hook. There are stoppers on the openings at both ends, and a fixed partition inside. Although this stretcher can be retracted, it also has some limitations. For example, this stretcher cannot achieve the effect of a cart. Present medical emergency trolley is generally very heavy, and it is also inconvenient to place on the ambulance, and there is not yet a kind of tool that stretcher and medical emergency trolley gather.
