Description
Technical field
This utility model relates to medical apparatus and instruments field, particularly relates to a kind of dialysis connecting line structure.
Background technology
Blood purification refers to and utilizes certain instrument and equipment, by outside blood samples of patients lead body, and some metabolic waste or noxious substance in certain procedures purged body, then blood is led back the process in body, main blood purification method mainly contains following several.
Hemodialysis (HD): utilize disperse and ultrafiltration principle the blood of patient, dialysis solution simultaneously to be introduced in filter for blood dialysis, blood and dialysis solution are reverse flow in the inside and outside both sides of dialyzer, by with film inside and outside the solute concentration gradient of both sides, gradient of dialysing and hydraulic pressure gradient, both sides concentration balance is reached by dispersion, to remove human body intracellular metabolic refuse, the material of needs can be supplemented simultaneously, correct electrolyte and acid base imbalance, but protein binding toxin and middle macromolecular toxins can not be removed.
Hemofiltration (HF): the filtering function imitating human body glomerule, utilize barometric gradient, by a kind of blood purification method that the harmful substance in blood is excreted by filter semipermeable membrane, hemofiltration can remove the small molecular toxin that liver renal failure produces, but more weak to the removing of protein binding toxin.
Hemodiafiltration (HDF): the advantage combining hemodialysis (HD) and hemofiltration (HF), namely medium molecular substance is removed by disperse high-efficient cleaning except small-molecule substance with by convection current high-efficient cleaning, reduce Complication of dialysis, improve the quality of life of patient, extend life cycle, reduce mortality rate.
Hemoperfusion (HP): the absorption principle utilizing the strong adsorbent such as active carbon or resin, the directly outer and adsorbent contact blood lead body, more solute is measured in absorption blood, remove endogenous or exogenous poisonous substance in blood, reach the object of blood purification, hemoperfusion mainly removes the fat-soluble macromolecular toxins that liver renal failure produces, and water solublity small molecular can not effectively be removed.
By hemoperfusion (HP) and hemodiafiltration (HDF) coupling, utilize the blood purification mode of three kinds of different mutual supplement with each other's advantages to remove various toxin in uremic patient body comprehensively, abundant clearing machine internal milieu, prevention and therapy long-term dialysis complication, improves the quality of life of patient.
In used hemoperfusion cascading hemodialysis filtering device, the vein segment of perfusion device be connected by connecting hose with the artery segment of filter for blood dialysis, displacement liquid replenishes venous chambers.Traditional connecting hose is that producer two of providing and delivering has the long 35cm of spiral interface, there is blood sampling point centre, two connects the vein segment of perfusion device and the artery segment of filter for blood dialysis respectively, for rearmounted method, from perfusion device blood out itself through a flowing at a slow speed, hyperlipidemia, then through the high ultrafiltration of filter for blood dialysis, flow is low, and pachyemia can produce transmembrane pressure and increase.Transmembrane pressure increases, machine alarm termination of pumping, and perfusion device inwall and resin stick a large amount of platelet and be activated, and easily blood coagulation phenomenon occurs.
Utility model content
The purpose of this utility model provides a kind of hemoperfusion cascading hemodialysis filtration system for above-mentioned problems of the prior art, displacement liquid is supplemented before dialysis filter after perfusion device, blood flow velocity in dialysis filter improves environment soon, at utmost, obviously can reduce the generation of blood coagulation, alleviate the operating pressure of nurse, clinic is promoted the use of, and method is simple, effect safety.
