Description
【Technical field】
The utility model belongs to haemofiltration apparatus technical field, and the anti-freezing in more particularly to a kind of synchronous blood collection procedure is born
Press blood screening pipe.
【Background technology】
Blood purification in daily life we it be referred to as dialysis, it is that the blood of patient is drawn outside body and passes through one
Kind purifier removes some of which morbid substance, purifies blood, achievees the purpose that treat disease.Blood purification includes：Blood
Dialysis, blood filtering, blood perfusion, plasma exchange, immuno absorbence etc..Although peritoneal dialysis not by outside blood lead body,
Its principle is the same, and haemodialysis is one of method for treating chronic kidney hypofunction.
At present in blood collection procedure, purified treatment is not carried out to blood in first time mostly, was particularly being donated blood
Cheng Zhong, blood donor donate blood liquid after medical staff's simple process just preserve, just transfer blood when it is desired to be used and purified,
This just affects therapeutic efficiency.As blood cleaning equipment Materials are rapid, emerge and such as adsorbed resin, inorganic diatom
On help the scavenging materials such as filtering agent, ultrafiltration membrane, but the utilization rate of blood purification material at present is not generally high, majority is used in blood
Post-processing.Therefore, how research synchronous purification blood or is developed in a kind of synchronous blood collection procedure in blood collection procedure
Blood cleaning equipment, it is made to have multiple functions, to improve medical efficiency, it appears particularly important.
【Utility model content】
The utility model provides the anti-freezing negative pressure blood screening pipe in a kind of synchronous blood collection procedure, to solve existing blood sampling
The problems such as equipment source blood sampling anticoagulant is low, degree of purification is low.
For solution more than technical problem, the utility model uses following technical scheme：
The utility model proposes the anti-freezing negative pressure blood in a kind of synchronous blood collection procedure to sieve pipe, including screening pipe, mistake
Filter membranous layer, the filtering film layer are built in screening pipe, and the filtering film layer includes the first film layer, the second film layer, third membrane layer,
First film layer is made of lignin and inorganic silicon, and second film layer on lignin and inorganic diatom by helping upper filtering agent group
Into the third membrane layer is made of hollow fiber blood filtering membrane.
Preferably, the screening pipe is Vacuum container.
Preferably, the inner wall of the screening pipe is coated with anti-coagulants coating.
Preferably, the filtering film layer diameter in the screening pipe is more than the screening pipe diameter without filtering film layer, with fixation
Filter position of the film layer in pipe is sieved.
Preferably, the aperture of the hollow fiber blood filtering membrane is 165-180 μm.
Compared with prior art, the utility model has the advantages that：
(1) the anti-freezing negative pressure blood screening pipe that the utility model is provided in a kind of synchronous blood collection procedure is simple in structure, real
It is strong with property, have the characteristics of anti-freezing negative pressure, convenient for promoting the use of；
(2) the utility model anti-freezing negative pressure blood screening pipe of simple structure and strong practicability, can connect, directly with blood taking bag
Objectionable impurities, virus, blood fat, low-density lipoprotein, low density cholesterol in blood collection procedure etc. is removed, has purified source blood
Liquid improves the quality of source blood.
