Description
Technical field
The utility model belongs to medical instruments field, is related to a kind of artery lateral line, and more particularly to a kind of haemodialysis is used
Artery lateral line.
Background technology
Haemodialysis is one of acute or chronic renal failure user's Replacement Therapy, and it is by by internal blood drainage
To external, through one in the dialyzer constituted without several hollow fibres, mass exchange is carried out by disperse convection current, body is removed
Intracellular metabolite waste, maintains electrolyte and acid-base balance, while removing moisture excessive in vivo, finally returns the blood by purification
It is defeated to arrive in user's body.
In whole During Cpb, blood is drawn by the rotation of dialysis machine blood pump by arterial puncture needle, is then passed through successively
Artery lateral line, dialyzer and vein lateral line are crossed, most feeds back into vivo, so goes round and begins again to dialysis through venipuncture needle afterwards
Terminate, whole process is time-consuming 4 hours.
After dialysis terminates, blood must be all fed back into vivo in external whole pipeline and dialyzer, that is, carries out closed
Blood back, step is：1) prepare>200mL physiological saline, branched pipe I is rinsed by infusion strap connection；2) pump speed is turned down, with
CBF is advisable less than or equal to 100mL, presss from both sides the hemostatic clamp I closed on artery lateral line, and the side of branched pipe I transfusion skin is rinsed while opening
Blood is to pump line in liquid stopping clamp on bar, flushing line, the time with<It is advisable within 20-30 seconds；3) pump is closed, is opened on artery lateral line
Hemostatic clamp I, by natural gravity effect feed back artery lateral line in proximal part blood；4) feed back after terminating, be again switched off artery
Hemostatic clamp I on lateral line；5) turn on pump again, continues to feed back blood；6) feed back after terminating, folder closes vein end clip；7) pin is pulled out,
Hemostasis.
The dialysis that clinically generally uses at present with artery lateral line as shown in figure 1, rinse branched pipe I and swivel joint it
Between transfusion pipeline section length be 2.08 meters, hold blood volume be about 30mL or so, during closed blood back, by gravity feed back pump
During the blood of front end, the problem of having more：1) time-consuming for blood back process, needs termination of pumping about 50 seconds or so, there is the risk of potential blood coagulation；
2) remained blood is more in woven hose, and increase patient's loses blood；3) 30mL blood does not pass through in returning step in woven hose
Filter screen, adds tiny thrombus into internal risk, also increases the risk of Fistula obstruction；4) make for a part of upper fistula
User, artery end pressure is high, and this device is difficult big during closed blood back, can only using general blood back mode, and one
As property blood back mode pollution probability greatly increase, it is serious to violate aseptic operation principle.
