Novel foldable stretcher for internal medicine emergency department

Abstract

The invention relates to the technical field of medical appliances, and particularly relates to a portable foldable stretcher for the internal medicine emergency department. The stretcher comprises a sleeve, a sleeve rod, a bent connecting rod, a handle, a transverse rod and a screen cloth, wherein the sleeve is connected with the sleeve rod and the bent connecting rod in a sleeving manner, and a chute and a first positioning button are arranged in the outer wall; stopping block is arranged at the end, extending into the sleeve, of the sleeve rod, and sliding position in the sleeve is realized by virtue of the first positioning button; the transverse rod is hinged with the sleeve; the bent connecting rod extends into the sleeve; the other end of the bent connecting rod is connected with the handle; a rectangular frame is enclosed by the sleeve, the sleeve rod and the transverse rod; the screen cloth is fixed in the rectangular frame; a bent foot-pad is arranged at the end part of the sleeve, and is provided with a hook; stoppers are arranged at openings at two ends of the sleeve, and a fixed separator is arranged inside the sleeve. The stretcher is reasonable in structure design, is assembled by a plurality parts by sleeved and axial connection modes, has small occupation space and carrying convenience when folded since the bent connecting rod and the transverse rod have axial-connection two-section structures, and can be used for providing two supporting heights when unfolded, is convenient to operate, and is an ideal substitute product for existing stretchers.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable emergency internal medicine folding stretcher. Background technique [0002] 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...

Problems solved by technology

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
