Portable anesthesia machine based on oxygen self-sufficiency

Abstract

The invention relates to a portable anesthesia machine based on oxygen self-supplying, comprising an anesthesia device (1) and being characterized by also comprising a self-supplying type oxygen source device (2) matched and connected with the anesthesia device (1), wherein the connection between the anesthesia device (1) and the self-supplying type oxygen source device (2) is of an easily detachable connecting structure; the oxygen source device (2) comprises a shell (2-1) with an air inlet, the shell (2-1) is internally provided with a filter (2-2), a positive booster (2-3), a cooler (2-4), an electromagnetic valve (2-5), a molecular sieve bed (2-6), an oxygen storage tank (2-7) and a pressure regulating valve (2-8); a PLC (Programmable Logic Controller) (2-15) and a running state displaying module (2-16) are arranged in the shell (2-1) of the oxygen source device (2), and the I / O (Input / Output) port of the PLC (2-15) is respectively connected with the positive booster (2-3), the electromagnetic valve (2-5) and the running state displaying module (2-16); and the running state displaying module (2-16) is connected with the pressure regulating valve (2-8). An oxygen generation system and an anesthesia respiratory system provided by the invention can realize seamless connection and oxygen self-supplying; meanwhile, the device can separately packaged, is portable and has no any risk in the transportation process.

Description

Technical field: [0001] The invention relates to an anesthesia machine, in particular to a portable anesthesia machine based on oxygen self-sufficiency. It belongs to the field of medical device technology. Background technique: [0002] At present, most anesthesia machines use compressed gas cylinders to supply oxygen, which cannot achieve self-sufficiency of oxygen. Because oxygen is an explosive gas, the use of gas cylinders to supply oxygen has the disadvantage of inconvenience to transport and carry. At the same time, the oxygen supply of gas cylinders is extremely limited, which cannot meet the continuous oxygen supply requirements of the anesthesia respiratory system, especially in the field or disasters. The problem is especially prominent in environments with many inconveniences. However, the oxygen generator in the prior art cannot meet the seamless connection with the respiratory system in terms of technical and physical conditions. In addition, the transportation o...
