Emergency ambulance uninterrupted oxygen generation and supply system

Abstract

The invention discloses an emergency ambulance uninterrupted oxygen generation and supply system which comprises an oxygen generation unit, an oxygen compression unit and an oxygen charging and supply platform which are sequentially connected, wherein a main control unit respectively controls the oxygen generation unit, the oxygen compression unit and the oxygen charging and supply platform; the oxygen generation unit is formed by sequentially connecting an oxygen generator, an oxygen buffer tank and an oxygen sensor through a pipeline; the oxygen compression unit is formed by sequentially connecting a drive pump, an oxygen compressor and a pressure sensor through a pipeline; the oxygen charging and supply platform is composed of a charging branch and an oxygen supply branch; the main control unit is composed of a touch screen in combination with a programmable logic controller (PLC); and the PLC is used for acquiring information of the oxygen sensor of the oxygen generation unit, the charging pressure sensor arranged at the compressed oxygen outlet of the oxygen compression unit, and the intake pressure sensor in the oxygen charging and supply platform, and controlling a normally open solenoid valve on the oxygen supply pipeline. The invention implements mobile uninterrupted oxygen generation and supply on the emergency ambulance, enhances the long-distance transportation capacity of the emergency ambulance, and has the advantages of reasonable technique and stable performance.

Description

technical field [0001] The invention relates to the technical field of oxygen preparation and oxygen filling, and more specifically, relates to a device for uninterrupted supply of oxygen source in an on-board oxygen bottle of an ambulance and control of oxygen source supply in the car. Background technique [0002] The ambulance is an important means of transportation for medical first aid, transport of the wounded between hospitals, and long-distance transport, and the effective supply of oxygen in the car is the key to the successful treatment of the wounded. At present, the oxygen supply equipment equipped with various emergency vehicles is generally two 10L oxygen cylinders. Due to the limited oxygen storage capacity of the on-board oxygen cylinders, the ability of ambulances to transport patients over long distances is greatly limited. In the long-distance transshipment, medical accidents often occur due to insufficient oxygen supply, resulting in unnecessary casualtie...

AI Technical Summary

Problems solved by technology

The existing problems are: 1) Increase the number of oxygen cylinders carried in the ambulance, occupying the limited use space of the ambulance, easily affecting the patients getting on and off the emergency vehicle, and sometimes even affecting the medical staff to carry out emergency treatment; 2) The transportation of high-pressure oxygen cylinders exists Security risks

The problems of this system are: 1) It is difficult to modify the existing emergency vehicles; 2) It is difficult to supply liquid oxygen during transportation; 3) Liquid oxygen is evaporative during daily storage, which is easy to cause waste

[0004] Chinese patent 200420054726.5 introduces a vehicle-mounted pressure swing adsorption oxygen generator that uses a compression pump and a vacuum pump to produce oxygen. The oxygen produced can not only be used for passengers in the car Normal oxygen consumption can also diffuse the remaining oxygen into the car. When the oxygen content in the car reaches a certain concentration, it will show the effect of an oxygen bar and improve the comfort of the car. The oxygen generator can increase the oxygen concentration in the space and is suitable for use To improve the breathing environment, unable to meet the medical emergency oxygen demand

Chinese patent 200820087034.9 introduces an oxygen compressor using an oxygen collection device, which is a large independent industrial oxygen compression device, and has a large volume, so it is not suitable for integration with the vehicle-mounted oxygen production system

Chinese patent 03209598.8 introduces a vehicle-mounted oxygen generator, which uses a DC / AC inverter to convert the low-voltage 12V DC power supply of the motor vehicle into a high-voltage AC power source to drive the vehicle-mounted oxygen generator. The oxygen generator has a small oxygen flow rate and low pressure. It does not have the function of filling the bottle with pressurized oxygen. It is used for the health care of ordinary vehicle occupants and is not suitable for patients in emergency vehicles.

Chinese patent 200420002875.7 introduces a vehicle-mounted pressure swing adsorption oxygen generator, which converts the vehicle-mounted 12V and 24V power sources into 220V AC power sources through an inverter device. This oxygen generator does not have the function of filling bottles with compressed oxygen, and is only suitable for the health care of ordinary vehicle occupants. , not suitable for use by ambulance patients
