Abstract
The utility model relates to the field of medical device equipmentapparatus, in and particularly relates to a dialysis connection pipeline structure. The dialysis connection pipeline orderly comprises a flexible pipe, a foam breaker, a pressure monitoring device and a spiral port, wherein a filtering device is arranged in the foam breaker and can filter blood cells and visible components activated in blood, not only can the formation of thrombus in the body be avoided, but also the blood damage loss of a patient can be reduced; the pressure monitoring device comprises a pressure monitoring protection device and can monitor the change of pressure during the process of blood dialysis perfusion in real time, thereby avoiding an accident.
Description
Technical field
This utility model relates to the medical apparatus and instruments field, relates in particular to a kind of dialysis connecting line structure.
Background technology
Along with the development of medical science and improving constantly of blood purification technology, Uraemia in telophase patient's life span prolongs year by year.Long-term dialysis complication such as renal osteodystrophy, intractable skin itching, sleep disorder, constipation etc. affect Quality of Life.Simple dialysis can only have scavenging action to small-molecule substance, and middle macromole toxin is not then removed effect.Blood perfusion device contains polymeric sorbent, can effectively remove the middle macromole toxin among the patients serum, such as parathyroid hormone, β2-microglobulin etc., but can not regulate water, electrolyte and acid base imbalance.The hemoperfusion combined with hemodialysis treatment refers to the blood perfusion device of connecting before hemodialyzer, utilize the blood purification mode of two kinds of different mutual supplement with each other's advantages to remove the interior various toxin of uremic patient body comprehensively, abundant clearing machine internal milieu, prevention and treatment long-term dialysis complication improve Quality of Life.
When Hemodialysis hemo perfusion, need to link to each other with the artery segment of dialyser by the vein segment of connecting line with perfusion device, conventional connecting line is that two ends have the middle flexible pipe that the blood sampling point is arranged of spiral interface, we find that blood coagulation does not occur perfusion device in the therapeutic process, treat and unloaded filling in 2.5 hours, unload and filled with rear continuation dialysis treatment 1.5 hours, because conventional connecting line does not have filtration, dialyser and pipeline have blood coagulation to occur.Because blood directly contacts with dialyzer in the blood dialysis, activated platelet and intrinsic coagulation approach, and activating complement, histanoxia and vascular endothelial injury caused, thrombin is formed increase, the inwall of perfusion device and resin particle have adhered to more platelet.We generally adopt normal saline blood back method flushing perfusion device dialysis pipeline when unloading filling, blood and lumen wall and perfusion device inwall precipitate have been diluted, make tube wall smooth, reduce blood viscosity, stop blood formed element to adhere to, the External Force Acting platelet that adds blood pump be activated and and visible component be rushed out, be adsorbed on the dialyser fiber and the pipeline of dialysing in, the defecator of venous chambers also causes visible component and platelet aggregation, continues easily to occur in the dialysis procedure blood coagulation phenomenon.
The generation of blood coagulation phenomenon causes more present dialysis centers to unload filling with air blood back method.But remaining blood volume is too many, and these often cause anemia.Some dialysis center is on the high side for fear of blood coagulation phenomenon heparin consumption, sometimes also needs the protamine neutralization.It also is unsafe in the patient body that the platelet that has activated and visible component are got back to, and easily causes the formation of thrombosis.
The utility model content
The purpose of this utility model is to provide a kind of novel dialysis connecting line for above-mentioned problems of the prior art, increased bubble trap, and in bubble trap, increased defecator, can effectively filter out platelet and the visible component of activation, abandon after unloading filling, can avoid continues to dialyse also can avoid forming in vivo thrombosis when producing blood coagulation, reduced the loss of blood samples of patients, increased pressure monitoring device in the connecting line the inside simultaneously, pressure changing in can the Real-Time Monitoring dialysis procedure in the connecting line, avoided dangerous generation, alleviated medical personnel's operating pressure, method simply is worth of widely use.
Dialysis connecting line described in the utility model comprises flexible pipe, bubble trap, pressure monitoring device, spiral port, and wherein said bubble trap two ends have flexible pipe to communicate; Flexible pipe A has spiral port A away from an end of bubble trap, links to each other with the vein segment of perfusion device by screw socket, and the blood in the perfusion device is introduced in the connecting line; Defecator is arranged in the bubble trap, can filter out by perfusion device and flow into platelet and the visible component that activates in the blood of connecting line, and other compositions in the blood can all pass through; Flexible pipe B has spiral port B away from an end of bubble trap, links to each other with the artery segment of dialyser by screw socket.
As a kind of preferred experimental program of dialysis connecting line described in the utility model, respectively there is a protective cap described spiral port A and spiral port B outer end.
As a kind of preferred experimental program of dialysis connecting line described in the utility model, described bubble trap also is connected with pressure monitoring device, and described pressure monitoring device comprises connecting hose and pressure monitoring protector.
As a kind of preferred experimental program of dialysis connecting line described in the utility model, described pressure protective device contains one can only pass through air and the intransitable film of liquid.
Described pressure monitoring device one end links to each other with bubble trap, and an end links to each other with dialysis machine, and the pressure changing in the energy Real-Time Monitoring connecting line in case pressure jump can be made a response the very first time, avoids accidents.
