Electric hoisting stretcher vehicle

Abstract

An electric hoisting stretcher vehicle comprises a universal wheel chassis, a liftable platform and a hoisting system, wherein the universal wheel chassis is in contact with the ground through four universal wheels (1-2) which are fixed at four corners of a chassis flat plate (1-1) respectively; a battery jar (1-3), a charger (1-4) and a frame (1-5) are placed on a plane; a lifting platform slide track is fixed on the plane; the liftable platform comprises a lifting platform (2-1), bearing seats (2-2), lifting rods (2-3), upper cross rods (2-4), screw rods (2-5), screw nuts (2-6), lower cross rods (2-7), slide blocks (2-8), polished shafts (2-9) with support seats, a worm gear speed reducer A (2-10) and a DC motor (2-11); the hoisting system comprises graspers (3-1), grasping racks (3-2), nylon tapes (3-3), take-up reels (3-4), a six-edge take-up spool (3-5), a worm gear speed reducer B (3-6), a DC motor (3-7), a lifting beam (3-8), a half shaft (3-9), a speed reducer (3-10), a reducing motor (3-11), a support rod (3-13), a support rod groove (3-14) and a bolt (3-15). The electric hoisting stretcher vehicle can be used for hoisting a stretcher electrically, so that a patient can be transferred between equipment and the stretcher vehicle.

Description

technical field [0001] The invention belongs to the stretcher trolley in the field of medical equipment, in particular to an electric lifting stretcher trolley, which uses a battery to store electric energy, uses a motor as power, and uses a lifting and lowering device to make the patient move on the emergency stretcher trolley, hospital bed, or operating bed. , Smooth transfer between diagnostic equipment. Background technique [0002] Now patients in hospitals often need to be transferred between emergency stretchers, hospital beds, operating beds, and diagnostic equipment. The equipment used is a stretcher. The form is transferred to a stretcher trolley or other equipment, or transferred from a stretcher trolley to other equipment. This process is labor-intensive and time-consuming, and will increase pain and even unnecessary injury to the patient due to uneven stress, position changes and body twisting. Sometimes the patient is injured or the wound is torn due to the m...

AI Technical Summary

Problems solved by technology

[0003] At present, in medical systems at all levels, stretcher carts mainly use the form of flat trolleys to transfer patients, so many people do it and the patients suffer.

Now from the published invention patents, the stretcher car is nothing more than two kinds of forklift type and roll-on type, both of which need to turn the patient, place the lifting board or conveyor belt under the patient, and do not It can achieve the purpose of transferring the patient safely without increasing the pain of the patient, without changing the position, so it has not been used clinically.
