Apparatus for enrichment of the breathing in air with oxygen

摘要

The invention refers to an apparatus for enrichment of the breathing in air with oxygen which may be used in medicine for the oxygenation of the body. The apparatus for enrichment of the breathing in air with oxygen contains a body 1, wherein it is placed an admission air conduit 2 provided with a forced-draught fan 3 and a filter 4. The admission air conduit 5 with a choke 6 placed onto the end thereof and an auxiliary air conduit 8 with a choke 9 installed in its middle part. The air conduits communicate by means of a channel 10, into which there are mounted permanent magnets 11 and a drawing fan 12. The channel is connected by means of a connecting branch 14 to the respiratory bag 15, provided with a regulating valve 16 and a mouth-piece 17. The forced-draught and drawing fans are attached to the low-voltage constant-current source. As permanent magnets there are used the niobium-ferrite magnets having the structure of perovskit, magnetized to saturation. The result of the invention consists in increasing the breathing in air enrichment efficiency without additional recharging of the oxygen mixture.
