Ambulance stretcher ladder board

Abstract

The invention relates to the field of medical devices, and particularly discloses an ambulance stretcher ladder board. The ambulance Stretcher ladder board comprises a ladder board body, an air cylinder and an air compressor. One end of the ladder board body is hinged to an ambulance bottom plate through an articulated shaft; the cylinder body of the air cylinder is hinged to the ambulance bottomplate, and a push arm hinged to a piston rod of the air cylinder is fixed to the ladder board body; two parallel slide rails are arranged on the surface of the ladder board body , multiple limiting units are arranged between the slide rails, and each limiting unit comprises a nozzle, a limiting plate and a limiting edge which are arranged from the hinged end to the free end in sequence; the ladderboard body is provided with a notch in which the nozzles are arranged; one end of each limiting plate is hinged to the two side walls of the notch, the limiting plates can cover the nozzles, and theair compressor and the nozzles are communicated through solenoid valves; the free end of the ladder board body is provided with control parts located in the slide rails, each control part comprises acontrol rod, a balance spring, a first press switch and a controller electrically connected to the solenoid valves, and the cylinder body of the air cylinder is provided with second press switches electrically connected to the controllers. Through the ambulance stretcher ladder board, the safety can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ambulance stretcher ladder. Background technique [0002] At present, in the emergency rescue process, ambulance personnel fix the wounded on a stretcher car or a stretcher, and carry them into an ambulance by manpower. In this process, if bumping or shaking will cause secondary injury to the wounded on the stretcher, if the wounded is overweight, it is not conducive to ambulance personnel to carry it into the ambulance. [0003] In view of the above problems, the tail of some ambulances is equipped with ladder plates, which are hinged on the floor of the ambulance, so that the ladder plates can be turned over. When the ambulance is running, the ladder board is turned upwards so that the ladder board is attached to the rear door of the ambulance in a vertical state, so the ladder board will not affect the form of the ambulance. When the wounded needs to be moved into the ambul...

AI Technical Summary

Problems solved by technology

However, when the stretcher is pushed into the ambulance compartment from the ladder, when the stretcher is on the ladder, the universal wheels are prone to deflection, which makes it difficult to control the direction of the stretcher

In addition, in the process of pushing the wounded from the ladder into the ambulance compartment, once the ambulance personnel let go of the stretcher, the stretcher will slide down under its own gravity, and when the stretcher slides to the ground, there will be a large vibration, which will cause secondary damage to the wounded

Therefore, the current ambulance ladder is less safe
