Description
Technical field
The utility model belongs to blood cleaning equipment technical field, specifically, more particularly to a kind of blood purification pipe
Road.
Background technology
At present, haemodialysis (HD) treatment and blood filtering (HF) treatment are uremia, acute and chronic renal failure syndrome latter stage
The resistance to primary treatment regimen with existence of patient.Haemodialysis and Hemofiltration for Treatment are that blood is introduced into haemodialysis by blood pump
Device (or filter) blood circuit side, while the dialysis fluid side of dialyzate introducing haemodialyser (or filter), dialyzate
With the small molecular substance in blood by the semi-permeable membrane in haemodialyser (or filter) by concentration gradient and pressure difference into
Row mass exchange removes in vivo metabolic waste, maintains electrolyte and acid-base balance, while removes moisture excessive in vivo, and
By defeated time of the blood by purification.Haemodialysis, filtration, perfusion etc. are referred to as blood purification.
Since blood has coagulability, it is necessary to carry out at anti-freezing when will carry out blood purification outside in vivo blood lead body
Otherwise reason can cause external blood coagulation, threat to life safety.There are two types of the anticoagulant methods now clinically used:Anticoagulant heparin and Chinese holly
Rafter acid anti-freezing.
Anticoagulant heparin is a kind of whole body anticoagulant methods, and principle is：Blood pump is introduced into blood in extracorporeal blood circuit, so
Heparin is added in calparine pipe with syringe afterwards, when ensureing that blood cycles in vitro, solidification will not be generated；Blood is net by blood
After changing device, also the bubble in blood is collected by concentration discharge by bubble trap, then by blood out of vein end defeated ex vivo.
After treatment end, then the heparin to being added in human body injection nucleoprotamine confrontation therapeutic process.Resisted on the market using heparin at present
Solidifying blood purifying pipeline mainly includes arterial line, venous line and the blood being connected between arterial line and venous line
Clarifier is separately installed with arterial puncture needle and venipuncture in the end of arterial line and venous line away from blood purification
Pin is equipped with artery bubble trap in arterial line close to one end of arterial puncture needle, artery bubble trap and arterial puncture needle it
Between pipeline on branch be connected with calparine pipe；Vein bubble trap is installed close to one end of venipuncture needle in venous line.Due to facing
Bed scheme is ripe, monitoring is simple, and this blood purifying pipeline using anticoagulant heparin is widely used in various blood cleaning equipments.
But there is also following shortcomings for anticoagulant heparin：There are hemorrhage risk and heparin may induced thrombocytopenia；Meanwhile this kind anti-
The patient that solidifying method is not suitable for internal haemorrhage and operation does not recover completely, the scope of application have certain limitation.
Citrate anticoagulation is a kind of partially anti-freezing function method, and principle is：It is connected at the arteriopuncture end of blood purifying pipeline
There is citric acid branch pipe, and citric acid is input in blood with infusion pump, prevent blood blood coagulation in cyclic process in vitro；In blood
The venipuncture end of liquid purification pipeline is connected with calcium solution infusion pipeline, and calcium solution is injected vein with syringe, supplement by
Cause the calcium being lost in adding citric acid.It is carried out in pipeline and clarifier that its anti-coagulation process is only cycled in vitro,
Therefore it is partially anti-freezing function.Citrate anticoagulation can overcome the shortcomings that anticoagulant heparin, but existing most of blood cleaning equipments are not
Possesses citric acid input channel.If carrying out citrate anticoagulation only uses more high-end blood cleaning equipment, these are high
The blood cleaning equipment at end use integrated blood purifying pipeline, have the characteristics that it is non-dismountable, involve great expense, brought to patient
Extremely heavy financial burden.This results in citrate anticoagulation although to have its technical advantage, but usage degree is not extremely popularized also.
