Stretcher for ambulance

Abstract

The invention discloses a getting-on stretcher for an ambulance in the field of medical emergency equipment. The stretcher comprises a stretcher body. The stretcher body is provided with a carrying platform frame for carrying a patient. Front supporting legs and rear supporting legs are arranged at the bottom of the frame body. Wheels are arranged at the bottoms of the front supporting legs and the rear supporting legs. The upper ends of the front supporting legs and the upper ends of the rear supporting legs are hinged to the bottom of the frame body. The front supporting legs and the rear supporting legs swing front and back through a movement assembly. The movement assembly comprises a guide rail arranged in the frame body, a first sliding block and a second sliding block capable of sliding front and back are arranged on the lower side of the guide rail and hinged to one end of a first inclined rod and a second inclined rod, and the other end of the first inclined rod and the other end of the second inclined rod are hinged to the front supporting legs and the rear supporting legs. A first limiting mechanism and a second limiting mechanism used for locking the first sliding block and the second sliding block are arranged on the frame body. The getting-on stretcher has the advantages that operation is convenient, the height can be adjusted, and ambulance getting on and off impact is small.

Description

technical field [0001] The invention relates to a stretcher for medical rescue, in particular to a stretcher for ambulances. Background technique [0002] When someone is injured, it is often necessary to send the injured to an ambulance on a stretcher so that the injured can be treated in time. As we all know, the "golden time" of first aid is very precious. For this reason, it is necessary to send the injured to the ambulance quickly. suffer further harm. The traditional boarding stretcher adopts a folding latch mechanism. When boarding the car, the boarding stretcher is pushed into the ambulance compartment. The swing rod connected with it rotates, and then transmits the pulling force to the torsion arm through the wire rope, and the torsion arm drives the connecting rod to rotate, and finally makes the locking buckle rotate to the unlocking position, thereby releasing the locking effect on the supporting leg. Continue to push the boarding stretcher to the interior of ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned boarding stretcher can achieve the purpose of getting on the bus by folding its supporting legs, it has the following disadvantages: one, in order to avoid the accidental folding of the supporting legs of the boarding stretcher during the non-boarding process and cause accidents, the boarding stretcher The unlocking part is not flexible, and it needs a large force to move backwards to release the locking effect on the supporting legs. Therefore, when the unlocking part is against the bottom of the compartment, it needs to be pushed harder, which makes the process of getting on the car It is not easy and convenient; 2. In actual operation, in order to move the unlocking part backward, the inertia of the boarding stretcher is often used when it is moving, that is, the boarding stretcher is pushed straight into the compartment from a distance without stopping, and the side of the compartment is used to The upper part collides with the unlocking part to move the unlocking part backward. Although this operation is time-saving and labor-saving, the injured will also be impacted to a greater extent. This impact is likely to aggravate the condition of the injured and even cause new harm

3. The height cannot be adjusted. When some passages with lower heights are encountered during the transportation process, they cannot pass smoothly
