Description

technical field [0001] The invention relates to the medical field, in particular to a stretcher bed for an ambulance that is easy to carry. Background technique [0002] The bed equipped on the existing ambulance is roughly divided into two classes: a class is a collapsible trolley type, and a class is a fixed type. These second class beds can usually only place one on the car, and are used for lying down for the rescued personnel. The bed surface is generally made of canvas or cushion materials, and the surface is soft and hard, and the comfort is poor. [0003] This type of product design usually has the following defects: one, due to the poor structure, the ambulance gives the bed injured and the sick people a lot of bumps when driving. Especially when long-distance transshipment or road ups and downs, it will bring pain to the wounded and sick. Two, due to poor integrity and unreasonable layout, only one bed can be placed on the ambulance, which affects the efficiency...

AI Technical Summary

Problems solved by technology

The bed surface is generally made of canvas or cushion materials, and the surface is soft and hard, and the comfort is poor

[0003] This type of product design usually has the following defects: 1. Due to the poor structure, the ambulance will cause larger bumps when the ambulance is driving.

Especially during long-distance transshipment or road ups and downs, it will bring pain to the injured and sick

2. Due to poor integrity and unreasonable layout, only one bed can be placed on the ambulance, which affects the efficiency of the ambulance

At the same time, there is no external assistance to carry the wounded to and from the car, which increases the work intensity of the rescue staff.

3. The traditional bed surface structure is inconvenient for patients to lift and release, and the rescue conditions of patients are affected.
