Abstract

The de-airing device for purifying blood has one box with water inlet, water outlet, air exhaust, dialysate joint and waste liquid joint. The water inlet is connected to the liquid inlet of the flow controlling choke; the liquid outlet of the flow controlling choke is connected to two pipelines, including the first pipeline connected to the liquid inlet of the first de-airing tank via a gear pump and the second pipeline connected to the liquid exhaust of the second de-airing tank via a second solenoid valve; the liquid outlet and the air exhaust of the first de-airing tank are connected separately to the dialysis joint and the air exhaust joint pipeline; and the liquid inlet and the liquid outlet of the second de-airing tank are connected separately to the waste liquid joint pipeline and the water outlet joint via a second gear pump. The present invention can avoid air embolism to blood for normal dialysis treatment.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a degassing device for hemodialysis and hemofiltration equipment. Background technique

[0002] Hemodialysis (HD) treatment and hemofiltration (HF) treatment are the main treatments for patients with uremia and acute and chronic renal failure syndrome to survive. Both treatment modes finally need hemodialyzer or hemofilter to remove toxins and excess water in the body. There is no essential difference in structure between hemodialyzer and hemofilter, both of which are composed of a large number of hollow fibers These hollow fiber tubes are semi-permeable membranes with high permeability. Small and medium molecular substances and water in blood can pass through freely, while larger molecules in blood (such as most proteins, plasma components, blood cells, etc.) ) cannot pass. Hemodialysis and hemofiltration treatment is to introduce blood into the hemodialy...
