Description

Double series-parallel suitching type blood perfusion connecting tubes of Y safety

Technical field

The utility model relates to haemodialysis medical equipment, especially it is a kind of it is easy to operate, prevent blood dialysis sudden and violent Dew mitigates medical staff's operation difficulty, prevents operating mistake, the highly-safe series-parallel suitching type blood of double Y safeties Perfusion connecting tube.

Background technique

Haemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy.It is by drawing internal blood Flow to it is external, through one by the dialyzer that forms without several hollow fibres, blood electrolyte similar with concentration containing body is molten Liquid (dialyzate) carries out mass exchange inside and outside hollow fibre one by one, through disperse/convection current, remove intracorporal metabolic waste, Maintain electrolyte and acid-base balance；Moisture excessive in vivo is removed simultaneously, and will be by the whole process of the blood recovery purified Referred to as haemodialysis.

Blood perfusion device is divided into active carbon perfusion device (disposable charcoal kidney) and primary according to the difference of built-in adsorbent Property use resin hemoperfusion apparatus.Blood perfusion device adsorbent is macropore resinene, is divided into 80/100/ according to loading amount difference 130/150/200/230/250/280/330/350.It is consistent applied to active carbon perfusion device, and ting model 80~130 is mainly answered For series connection perfusion of dialysing for Molecular Adsorption in uremia.150~280 are applied to the absorption of poisoning toxin, and 280~330 answer For immuno absorbence and hepatopathy field.Absorption principle: absorption principle is consistent with active carbon, by intermolecular Van der Waals force, quiet Toxin is fixed in hole by electro ultrafiltration and hydrogen bond.Advantage: adsorption rate is high, nothing falls off, is safer without external source.

Existing blood perfusion device is in blood dialysis, and haemodialysis is generally four hours, by resin The dialysis time of blood perfusion device is two hours, and another two hour needs replacing dialysis in operation by dialysis machine Path.In the prior art, it is realized by supravasal clip, clip quantity is more, and it is inconvenient, it is unfavorable for medical staff's operation, For the safety for guaranteeing patient and medical staff, needs to avoid exposure and contact.Need it is a kind of it is easy to operate, prevent haemodialysis Process is exposed, mitigates medical staff's operation difficulty, prevent operating mistake, highly-safe double Y safeties switch in series and parallel Formula blood perfusion connecting tube.
