Intelligent constant-pressure oxygen supply equipment for medical first aid

Abstract

The invention belongs to the technical field of medical oxygen supply, and discloses intelligent constant-pressure oxygen supply equipment for medical first aid. The equipment comprises an oxygen bottle body, an elastic pressing and pushing device is bound outside the oxygen bottle body, an oil cylinder is fixedly mounted at the bottom of an inner cavity of the oxygen bottle body, a second piston rod is arranged in the inner cavity of the oil cylinder in a sleeved mode, and the top end of the second piston rod extends out of the oil cylinder. According to the intelligent constant-pressure oxygen supply equipment for the medical first aid, a first spring always generates downward thrust on hydraulic oil in an oil injection cavity; when a stop valve is kept an opened state, the hydraulic oil continuously flows into the second piston rod, so that the second piston rod pushes a compression block to rise to compress the inner cavity space of the oxygen bottle body; the oxygen above the compression block is compressed to increase the pressure; and thus, in the continuous oxygen consumption process, the compression block continuously compresses the oxygen storage space in the oxygen bottle body, the pressure of the oxygen in the oxygen bottle body is increased, and the pressure cannot be gradually reduced along with consumption.

Description

technical field [0001] The invention belongs to the technical field of medical oxygen supply, in particular to an intelligent constant-pressure oxygen supply equipment for medical first aid. Background technique [0002] Oxygen supply equipment is a commonly used equipment in the field of medical equipment. The existing medical equipment that can supply oxygen at constant pressure is located inside the hospital. Small constant-pressure oxygen supply equipment will be used in ambulances to supply oxygen to patients. [0003] However, the volume of the above-mentioned two kinds of constant pressure oxygen supply equipment is inconvenient to carry. Therefore, in the medical emergency process, for example, when the ambulance arrives at the destination, the patient urgently needs oxygen supply inside the building, and the patient needs to be transferred to the ambulance. Oxygen supply at constant pressure can only be carried out on the ground. During the transfer process, general...

Problems solved by technology

[0003] However, the volume of the above two constant pressure oxygen supply equipment is inconvenient to carry. Therefore, in the medical emergency process, for example, when the ambulance arrives at the destination, the patient urgently needs oxygen supply inside the building, and the patient needs to be transferred to the ambulance. Oxygen supply at constant pressure can only be carried out on the ground. During the transfer process, generally only an oxygen bag can be used for temporary oxygen supply. This kind of oxygen bag or small oxygen cylinder does not have the function of constant pressure oxygen supply, so that during the process of oxygen supply, the oxygen Consumption is too fast or the oxygen supply continues to decrease due to unstable pressure, which brings certain difficulties to medical emergency work, and it is difficult for patients to receive high-quality assistance

[0004] The present invention aims at the shortcomings of the existing medical emergency oxygen supply equipment that cannot combine portability and constant pressure, and proposes a new method that integrates the two characteristics of portability and constant pressure
