Abstract

The invention relates to a portable respirator based on the self-supply of oxygen, which comprises a respirator (1), and is characterized by also comprising a self-prepared oxygen source device (2), wherein the respirator (1) and the oxygen source device (2) are connected by an easily-detachable connecting structure; the oxygen source device (2) comprises a shell (2-1) with an air inlet; a filter (2-2), a supercharger (2-3), a cooler (2-4), an electromagnetic valve (2-5), a molecular sieve bed (2-6), an oxygen tank (2-7), a pressure regulating valve (2-8), a power module (2-14), a program logic controller (PLC) (2-15) and an operation state display mode (2-16) are arranged in the shell; one of the input / output (I / O) ports of the program logic controller (PLC) (2-15) is connected with the signal input / output end of the supercharger (2-3); another I / O port of the program logic controller (PLC) (2-15) is connected with the signal input and output end of the electromagnetic valve (2-5); and the left I / O port of the program logic controller (PLC) (2-15) is connected with the one of the signal input / output ends of the operation state display mode (2-16). In the invention, seamless connection and oxygen self-supply can be realized, and the portable respirator has the characteristics of portability, safety, reliability and wide application range.

Description

Technical field: [0001] The invention relates to a ventilator, in particular to a portable ventilator based on oxygen self-sufficiency. It belongs to the technical field of medical equipment. Background technique: [0002] Currently, clinical ventilator systems require an external central air supply system or gas cylinders to provide oxygen. However, the central gas supply system has disadvantages such as immobility and high energy consumption, so it is not suitable for field medical operations. Gas cylinder supply can be moved at will, but because oxygen is an explosive gas, the use of gas cylinders for oxygen supply has the disadvantages of inconvenient transportation and portability. Especially in the environment where there are many inconvenient conditions such as the field or a disaster place, the problem is particularly prominent; in addition, the transportation of oxygen is strictly limited, so the oxygen supply of the gas cylinder also has the shortcoming of a smal...
