Adjustable stretcher capable of being carried by many people in medical field

Abstract

The present invention belongs to the field of stretchers, and especially relates to an adjustable stretcher capable of being carried by many people in a medical field. The adjustable stretcher comprises a lying plate, a first adjustment mechanism, a second adjustment mechanism and an expansion link mechanism. The first adjustment mechanism and the second adjustment mechanism are symmetrically installed at two sides of the lower surface of the lying plate; one end of the expansion link mechanism is connected with the first adjustment mechanism, and the other end of the expansion link mechanismis connected with the second adjustment mechanism; when a stretcher-carrying person at one side of the stretcher shakes or slips, it is ensured that overturning of the stretcher is not generated due to single-side force to protect a person lying on the stretcher from falling from the stretcher and ensure the safety of the person lying on the stretcher; and when four people go through a corner of the stairs or a corner of a narrow alley while carrying the stretcher, the positions of persons located at two sides of the stretcher are relatively staggered to reduce the lateral dimension of the stretcher and allow the stretcher to be more easily carried to pass through the corner of the stairs or the corner of the narrow alley.

Description

technical field [0001] The invention belongs to the field of stretchers, in particular to an adjustable stretcher that can be carried by multiple people in the medical field. Background technique [0002] At present, the traditional stretcher is widely used as a simple tool for transporting people. It is carried by two people one after the other, and the weight of the stretcher and the person on the stretcher is only carried by the arms of the two people; When passing the corner of the stairs or the corner of a narrow alley, it is more difficult for two people to carry the stretcher. The strength of the arms cannot fully act on the stretcher, and the stretcher is easy to slip from the hand due to instability, which endangers the stretcher. People's safety; in order to ensure safety when passing the corner of the stairs or the corner of the narrow alley, it is necessary to add one person on both sides of the stretcher; there is not enough space for four people at the corner o...

[0002] At present, the traditional stretcher is widely used as a simple tool for transporting people. It is carried by two people one after the other, and the weight of the stretcher and the person on the stretcher is only carried by the arms of the two people; When passing the corner of the stairs or the corner of a narrow alley, it is more difficult for two people to carry the stretcher. The strength of the arms cannot fully act on the stretcher, and the stretcher is easy to slip from the hand due to instability, which endangers the stretcher. People's safety; in order to ensure safety when passing the corner of the stairs or the corner of the narrow alley, it is necessary to add one person on both sides of the stretcher; there is not enough space for four people at the corner of the stairs or the corner of the narrow alley At the same time, it passed smoothly, and it also failed to keep the stretcher stable and ensure the safety of the person sitting on the stretcher; when four people were carrying the stretcher on a rough or slippery road, people walked with one foot deep and one foot shallow. It may cause people on one side of the stretcher to shake or slide, resulting in uneven force on both sides of the stretcher, and swing up and down on both sides of the stretcher; if the swing is severe, the person sitting on the stretcher is likely to fall off the stretcher; Personal safety lacks the necessary protection, so the purpose of safely transporting the wounded or sick cannot be achieved
