Abstract

A conventional medical purpose oxygen is contained in cylinders with the disadvantages of high producing power consumption, a plurality of sections and unsafe factors in transport and use. The utility model provides a simple medical purpose oxygen-rich respiratory gas device, composed of an air compressor (1), a buffer tank (2), a hollow fiber membrane pipe (3), a discharge valve (4), and a flow meter (5) connected orderly. The hollow fiber membrane pipe can filter harmful impurity in the air, and increase the oxygen content in the air from 20.9% to more than 40%, providing oxygen-enriched air appropriate to medical purpose. The device is suitable for all medical authorities required medical purpose oxygen, especially suitable for minor scale medical units in remote districts.

Description

Medical oxygen-enriching device
This utility model belongs to armarium, particularly a kind of medical oxygen-enriching device.
The medical oxygen that uses all is the steel cylinder packing at present, by oxygen installation oxygen is filled to and delivers to medical institutions in the oxygen cylinder.The power consumption of this medical oxygen production method is big, and carrying labor intensity is big, and there is unsafe factor in the use of high-pressure oxygen cylinder.
The purpose of this utility model provides a kind of medical oxygen-enriching device that adopts the hollow fiber separating film device, can directly produce medical oxygen rich gas in the medical institutions that use medical oxygen.
According to this utility model, with pipeline air compressor is connected to a surge tank, be connected to the hollow fiber separating film pipe, at drain valve of a port of export connection of diffusion barrier pipe, another port of export connects an effusion meter and sends medical oxygen-enriched air.Directly this medical oxygen-enriched air is received the patient by the side of with sebific duct.
According to this utility model, air enters surge tank behind air compressor, air admission hollow fiber separating film pipe after buffering, after the separating film system of air in this diffusion barrier pipe separates, remove various objectionable impurities contained in the air effectively, and airborne oxygen content is brought up to more than 40% by 20.9%, the oxygen enriched product quality that is obtained reaches the medical oxygen index of pharmacopeia defined fully, can be directly used in the patient.
According to medical oxygen-enriching device of the present utility model, simplified the production technology of medical oxygen greatly, reduced a series of intermediate links, reduced energy resource consumption, guarantee safety oxygen.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is this utility model structured flowchart.
As shown in Figure 1, medical oxygen-enriching device of the present utility model is coupled together with pipe fitting successively by air compressor (1), surge tank (2), hollow fiber separating film pipe (3).An outlet of hollow fiber separating film pipe (3) air valve (4) that runs in, another outlet connects effusion meter (5), receives the sick bed next door by sebific duct again.
During operation, after connecting with the mains to air compressor machine, the switch of opening on the sebific duct can be supplied with oxygen-enriched air to the patient.
In one embodiment, the air pressure of air compressor machine output is 0.7MPa, and flow is 3m 3/ h.The hollow fiber separating film pipe is produced by the Dalian Chemistry and Physics Institute of the Chinese Academy of Sciences.The effusion meter rate of discharge is 0.24m 3About/h.
This utility model is applicable to the medical institutions that all need medical oxygen, is specially adapted to remote region, the less medical institutions of scale.
