Abstract

The invention discloses a stretcher, comprising two stretcher bars, handles arranged at the two ends of each stretcher bar and a bed body connected with the two stretcher bars; an automatic telescopic reel is arranged on one handle at one side of two handles at each end of the stretcher; one end of a carrying belt is connected with the telescopic reel of each handle at one side, and the other end of the carrying belt is connected with each handle on the other side. Each automatic telescopic reel comprises two gears and a rotary shaft for connecting the two gears; and one volute spiral spring is arranged at the outer side of each gear. Each automatic telescopic reel is provided with a locking device. In each reel, the volute spiral spring provides rotary acting force (or torque) to the reel, so that the loose carrying belt is reeled. When the carrying belts are pulled, the reels are enabled to rotate, and the volute spiral springs connected with the reels are also enabled to rotate along the same direction. The rotary reels reversely twist the springs, if the carrying belts are loosened, the springs restore until the carrying belts are tightened up.

Description

technical field [0001] The invention relates to a medical stretcher, in particular to an ambulance stretcher with adjustable posture. Background technique [0002] Stretcher is a common tool for transporting emergency patients. At present, the clinically used stretcher mainly consists of two frame bars and a bed. The two frame bars are parallel to each other and the bed is tied in the middle. Yet in mountain first aid, post-earthquake rescue, and other rugged roads with many slopes, the traditional stretcher has a single structure and does not have the function of keeping the sick and injured patients lying horizontally. When the slope of the terrain is large or when going up and down the stairs, because the bed and the lifting rod of the traditional stretcher are fixedly connected, the angle of the bed always tends to be consistent with the inclination of the slope, and the inclination of the injured and sick patients on the stretcher is also relatively large. It is not go...
