Automatically leveled type multifunctional rescue stretcher

Abstract

The invention belongs to the field of medical conveying appliances, and particularly relates to an automatically leveled type multifunctional rescue stretcher. In order to cope with the characteristics of complex locality and various disastrous conditions during the field rescue, the automatically leveled type multifunctional rescue stretcher which mainly comprises a left lifting rod, a right lifting rod both located at the top part, four suspension rods and a stretcher bed located at the bottom is provided. Four rotation pairs composed of the lifting rods, the suspension rods and the stretcher bed encircle to form two isosceles triangle hanger frames; the stretcher bed is automatically leveled when persons climb slope or get down slope by utilizing moment of force generated by the gravities of the ill and wounded persons and the stretcher bed; and the damping stabilization function of the stretcher bed is realized by utilizing a friction force between stabilizing belts and the lifting rods. The lifting rods, the stabilizing belts, the suspension rods and the stretcher bed are connected by pins; and a rescuer can detach the stretcher into two simple stretchers based on the practical need so as to be used for conveying a common ill and wounded person and an ill and wounded person with fracture respectively. As the relatively angles of the stretcher bed and the lifting rods can be locked, the automatically leveled type multifunctional rescue stretcher after being locked can serve as a simple tent, a simple operating table and a double-layer stretcher.

Description

technical field [0001] The invention belongs to the field of medical conveying appliances, in particular to an automatic horizontal multifunctional rescue stretcher. Background technique [0002] Stretchers are widely used in war or disaster rescue activities as the most basic rescue tool for transporting wounded and sick people. Currently commonly used are simple stretchers, ordinary stretcher vehicles and semi-automatic stretcher vehicles, etc., in view of the earthquake-stricken area surrounded by mountains, complex terrain, and inconvenient transportation, commonly used simple stretchers or stretcher vehicles have very limited effects in this case. However, maintaining the horizontal state of the stretcher is a basic requirement in the rescue process. When rescue is carried out under the conditions of steep mountain slopes and complicated road conditions, in order to maintain its horizontal state, the rescue process not only requires more people, but also requires more r...

Problems solved by technology

[0004] The basic working principles of the existing self-balancing stretchers are all ingenious and feasible, but there are still the following defects: 1) the function is single, and it is difficult to meet the multiple requirements of field rescue; 2 ) The buffer device is not perfect, or the automatic leveling function is too flexible, and the wounded and sick people tend to swing automatically on it, which is easy to produce a sense of insecurity, or the structure for realizing the buffering effect is relatively complicated and bulky
