Self-balancing stretcher

Abstract

The invention relates to a self-balancing stretcher. The stretcher comprises a first framework layer, wherein a second framework layer and a third framework layer are arranged on the inner side of the first framework layer in turn; two support rods in a length direction or a width direction of the second framework layer are rotatably connected with two support rods on the first framework layer respectively, and the other two support rods on the second framework layer are rotatably connected with two support rods on a third framework layer; the connection joints of the first framework layer, the second framework layer and the third framework layer are positioned in the center of the support rods to which the connection joints belong respectively; a sliding mechanism is arranged on two support rods in the length direction of the third framework layer respectively; the third framework layer is in sliding connection with a fourth framework layer by the sliding mechanism; two support rods on the fourth framework layer which are connected with the third framework layer are arc-shaped; fastening bolts are arranged on the sliding mechanism; and the inner side of the fourth framework layeris connected with a bed surface. The stretcher of the invention has the advantages of high vibration damping performance, capacity of automatically adjusting the balance, simple structure, convenientand flexible use and low cost.

Description

technical field [0001] The invention relates to a medical transportation device, in particular to a stretcher which can automatically adjust the inclination angle of the stretcher so as to maintain the balance of the stretcher itself. Background technique [0002] A stretcher is a commonly used tool for transporting patients and wounded. For example, it is used to transfer injured people during natural disasters such as earthquakes. PET (positron emission computed tomography) and CT (computer X-ray tomography) are performed on patients in hospitals. Scanning), MRI (nuclear magnetic resonance) and other examinations, a special stretcher bed is also required to transport the patient to the examination bed of the examination equipment. [0003] In the prior art, there are many styles of stretchers. The most commonly used stretcher is generally composed of two lifting bars, and a whole piece of cloth is fixedly connected between the two lifting bars. When transporting a patient,...

Problems solved by technology

Although this stretcher has a certain automatic balancing function, it is difficult to overcome the vibration caused by the left and right shaking of the stretcher when it is in use, which will bring discomfort to the patient; The production and installation of the balance board, supporting board and runners are very inconvenient; the reliability is also poor during use, and the runners are easy to get stuck when moving in the chute or the hanging lug, which affects the normal use
