Description
Technical field
This utility model relates to a kind of medical connector, relates in particular to a kind of movable catheter adapter of extracorporeal circulation blood circuit, the movable catheter adapter of a kind of extracorporeal circulation blood circuit specifically.
Background technology
Blood purification is called as " hemodialysis " in daily life, in blood lead body outer circulation blood vessel with the patient, and remove some morbid substance in blood by apparatus for purifying blood, then the blood after purifying returns in human body again, to reach the purpose of the diseases such as treatment nephropathy, hematopathy, metabolism endocrinopathy, high globulin disease, this process namely is called blood purification.Extracorporeal circulation blood circuit is a kind of medical apparatus and instruments as blood channel when purifying for blood, and apparatus for purifying blood refers to the medical apparatus and instruments such as hemodialyzer, filter for blood dialysis and transfusion filters, when blood purification, extracorporeal circulation blood circuit must with the apparatus for purifying blood use that complements one another, and proved extracorporeal circulation blood circuit and the supporting compatibility of apparatus for purifying blood in long-term medical practice, namely science, the reasonability of the joint design that is connected with apparatus for purifying blood of extracorporeal circulation blood circuit are the keys of blood purification operation.
extracorporeal circulation blood circuit is applied in decades clinical, product structure is constantly being weeded out the old and bring forth the new, but the joint that is connected with apparatus for purifying blood of extracorporeal circulation blood circuit, being commonly called as " catheter adapter " still exists following design not enough: mostly extracorporeal circulation blood circuit catheter adapter in the market is fixed catheter adapter, be that catheter adapter is designed to an integrated injection plastic, although the pertinent regulations of China's relevant industries standard have been satisfied in the design of its size, to have solved basic reduction to leak the compatibility that blood and air enter risk, but well-known extracorporeal circulation blood circuit pipe be one can carry the whole blood of human body pipeline, its pipeline is sufficiently long, when the catheter adapter of sufficiently long like this pipeline and apparatus for purifying blood spin (apparatus for purifying blood in the market is all also fixing non-rotatable from the standard interface of establishing), always can cause the extracorporeal circulation blood circuit pipe to loop along with being rotatably connected of catheter adapter, distortion, thereby cause affecting the stability of blood flow in the blood purification process, produce risk, although there is in addition well-advised medical worker pipeline can be looped, the part of distortion is unrolled and is adjusted, also bother very much but operate because pipeline is oversize, fixed catheter adapter is when being used in blood purification with apparatus for purifying blood in other words, its safety, stability and operability are not high.
Now people also have and make some trials and make such problem up, but some structural designs during these are attempted are the Hough card structure, require very high to the accuracy of manufacture, be unfavorable for batch production, particularly the catheter adapter of Hough card structure can be opened to power voluntarily because spinning when spinning with apparatus for purifying blood, causes the risk that more fearful connection is tight, leak blood.
