stretcher stretcher

Abstract

A telescopic stretcher, including two longitudinal rods and a plurality of connecting horizontal rods connecting the two longitudinal rods, the longitudinal rods are composed of nested outer hollow tubes and inner hollow tubes, and the inner hollow tubes of the two longitudinal rods are symmetrical It is arranged at the same end of the stretcher, and a through groove cooperating with the end of the connecting cross bar is arranged on the inner hollow tube along its axial direction, and a compression spring is arranged in the through groove, which is located in the through groove, and the adjacent two The root connecting cross bars are connected by compression springs. A horizontal section is arranged in the middle of the connecting cross bar, and the two ends of the horizontal section are bent upwards, and are matched and connected with corresponding parts of the two vertical bars respectively. In the present invention, since the through groove is arranged inside the inner hollow tube and the compression spring is arranged in the inner hollow tube, when the inner hollow tube of the stretcher retracts toward the outer hollow tube, the connecting cross bar can also shrink backwards with the compression of the compression spring , while avoiding the interference caused by fixing the connecting cross bar, finally the purpose of stretching the stretcher can be realized without reducing the connecting cross bar.

Description

technical field [0001] The invention relates to a medical stretcher, in particular to a stretchable stretcher. Background technique [0002] With the development of society, there are more and more high-rise buildings, but because the space of the elevator room is narrow and small, it will be very inconvenient when transporting a patient lying down from the high-rise. In order to solve this problem, a medical stretcher in the prior art It can be roughly divided into two types, one is foldable and the other is retractable. In telescopic stretchers, stretching is generally achieved by increasing or reducing the unsupported space. Using such a stretcher, when encountering a patient with a large weight, the strength of the stretcher will be insufficient, thereby causing potential safety hazards, and even accidents, which will bring additional injuries to the patient. Contents of the invention [0003] In order to solve the above technical problems, the present invention prov...
