Detachable self-balancing stretcher

Abstract

A detachable self-balancing stretcher comprises a main stretcher, an inner side adjustable stretcher and an outer side fixed support stretcher, wherein the main stretcher is assembled on a stretcher support of the inner side adjustable stretcher, and a bearing is installed between the inner side adjustable stretcher and the outer side fixed support stretcher. One end of an electric drive pusher is fixed on an inner side reinforcing member of the inner side adjustable stretcher, the other end of the electric drive pusher is fixed on an outer side reinforcing member of the outer side fixed support stretcher, an obliquity sensor is installed below a main shaft, real-timely detects the inclination angle of the stretcher, and sends the angel data to a controller, the electric drive pusher can be controlled by the controller to drive the inner side adjustable stretcher to rotate around the main shaft under slight bearing resistance, so a function of automatically adjusting the stretcher to keep horizontal is realized.

Description

technical field [0001] The invention is a detachable self-balancing stretcher bed, which belongs to a self-balancing stretcher which can run safely and stably on flat ground, stairs and undulating terrain. Background technique [0002] A stretcher is a commonly used rescue tool for transporting patients and the wounded. On the one hand, in various disasters and disaster scenes, the roads are rough, the terrain is undulating, and the slope changes greatly; Excessive inclination during the handling process will often aggravate the patient's pain and aggravate the patient's condition, especially for patients with bleeding, fractures, internal injuries, etc., and even affect their life safety. Therefore, during transportation, high requirements are placed on the stability of the stretcher. How to take effective measures to avoid tilting and reduce secondary injuries has become a major problem in rescue work. [0003] So far, domestic research on self-balancing stretchers is st...

AI Technical Summary

Problems solved by technology

[0003] So far, domestic research on self-balancing stretchers is still less, and there are also stretcher structures that can automatically adjust the balance in the prior art, but there are some deficiencies, such as the Chinese utility model patent "A Kind of Simple Balanced Stretcher" (Notice No. CN202027814U), when going uphill or downhill, you need to manually operate the handle to adjust the angle of the stretcher. The accuracy and stability of the adjustment depend entirely on the proficiency of the ambulance personnel, which is difficult to guarantee.

The self-balancing stretcher device in other studies may not be able to prevent overturning well due to design flaws, poor safety and stability, or due to complex structure and high cost, it is not practical under special conditions
