Artificial system for supporting liver and kidney

Abstract

The invention discloses an artificial liver and kidney supporting system, which is characterized by the following: connecting output tube of human body blood with blood inlet of the filter; connecting the blood inlet of the filter to blood inlet of plasma separator; communicating the outlet of the plasma separator with inlet of venous pot; connecting input pipe of human body blood to the outlet of the venous pot; connecting film outer up interface of the filter to waste liquid bag through waste liquid pipe; cascading heater with isosmotic solution bag; dividing to two road; connecting one road to film outer lower interface through the second peristaltic pump; communicating the third peristaltic pump with the inlet of the venous pot; connecting the film outer lower interface of the plasma separator to carrier pipe of the separating matter; cascading the separating matter carrier pipe with infusion device through the forth peristaltic pump; communicating with the inlet of the venous pot. This invention increases survival rate of liver and renal failure patient.

Description

technical field [0001] The invention relates to a medical device, especially a medical artificial liver and kidney support system for removing exogenous and endogenous poisons, wastes or other harmful substances in patients with liver and kidney failure. Background technique [0002] Liver and kidney failure is the most common form of multiple organ failure. Patients with liver and kidney failure have a lot of toxins in their blood, including albumin-binding substances (such as bilirubin) and large amounts of water-soluble small and medium molecular toxins. Common blood purification methods and toxin removal methods are relatively simple, and are introduced one by one below: [0003] Hemodialysis—Using the principles of diffusion and ultrafiltration to simultaneously introduce the patient's blood and dialysate into a dialyzer (artificial kidney). Blood and dialysate flow in opposite directions on the inside and outside of the dialysis membrane. With the help of the solute c...

AI Technical Summary

Problems solved by technology

[0008] At present, the treatment mode of blood purification equipment for the treatment of liver and kidney failure at home and abroad is relatively simple, and often only supportive treatment for liver failure or renal failure can be performed alone, and they are not thorough in removing toxins

However, to remove the toxins of liver and kidney failure at the same time clinically often requires multiple devices to be carried out at the same time (or sequentially), which is inconvenient to operate, and the treatment cost is too high, and the best treatment time is likely to be delayed due to the prolonged treatment time
