Description
Technical field
This utility model relates to a kind of medical equipment, particularly a kind of additional infusion metering that can realize sampled plasma and displacement liquid, equivalent, the even plasmapheresis device of infusion.
Background technology
Plasmapheresis is one of important means that purifies the blood in the modern biomedical engineering field; Its ultimate principle is to utilize blood separator; Become blood plasma and hemocyte composition (erythrocyte, leukocyte, platelet) in external blood separation with the patient; Discard the blood plasma that contains harmful morbid substance then, the displacement liquid replacement blood plasma with equivalent feeds back to hemocyte composition and plasmapheresis liquid in patient's the body more together.The blood separation technology of the more employing of plasmapheresis at present is that the membrane filtration mode is carried out, and this mode is prone to the hemocyte breakage, thereby the personnel that cause injure.The another kind of plasmapheresis that uses centrifugal separate mode to carry out; Because replenishing of displacement liquid through plug-in displacement liquid bag; Feed back with displacement liquid is additional and carry out synchronously, can not fully mix, cause the preceding few back of displacement liquid infusion process many; Consumption control is inaccurate, and more displacement liquid is gathered discarded during recirculation.
Summary of the invention
In view of the deficiency of present plasmapheresis usual way, the purpose of this utility model is a kind of disposable plasmapheresis device that utilizes centrifugal blood separator to carry out plasmapheresis of design.
The novel plasmapheresis device that this utility model proposes is realized above-mentioned purpose through following architectural feature:
This plasmapheresis device, comprise that blood taking needle, perforator I, anti-freezing liquid pipe, blood taking tube, liquid stopping clamp, needle adapter, three way cock I, pressure monitor, blood adopts defeated pipe I, pressure monitoring pipe, blood filter, blood and adopt defeated pipe II, pump line, spacing card, blood tube, blood separation cup, three way cock I; Blood taking needle be linked in sequence blood taking tube, liquid stopping clamp, needle adapter and three way cock I; Three way cock I connects blood respectively and adopts defeated pipe I and anti-freezing liquid pipe; The anti-freezing liquid pipe connects pump line and perforator I; The spacing card of bonding on the pump line; Blood filter is gone into end connection blood and is adopted defeated flexible pipe I, and two outfans one tunnel connect pressure monitoring pipe and pressure monitor, and another road connects blood and adopts the defeated II of managing; Blood is adopted defeated pipe II and is linked to each other with an end of three way cock's II; Three way cock's II one the tunnel is connected through the cone joint of blood tube with the blood separation cup in the two ends in addition, and cone joint is connected with the plasma collection bag with the plasma collection pipe, it is characterized in that in other two ends of threeway II that one the tunnel has connected the displacement liquid infusion pipeline that is made up of displacement liquid pipe, perforator II and intermediate plate.
The displacement liquid pipe is connected with displacement liquid bag on being suspended on the blood separator electronic scale through the perforator II, can obtain the weight that displacement liquid replenishes infusion constantly, makes treatment more accurate.
In order to increase the collection capacity of discarded blood plasma; Frequent change plasma collection bag when avoiding operating; This plasmapheresis device will be connected two plasma collection bags through a three way cock with the plasma collection pipe that cone joint on the blood separation cup links to each other, and the bag tail of these two plasma collection bags is communicated with through connection tube.Plasma collection bag utilization bag WEILIAN is taken over and has been realized high capacity dress liquid function, need not weigh in whole plasmapheresis process and control and frequent change plasma collection bag, makes more convenient to operate.
The operation principle of this utility model is following:
This novel plasmapheresis device and centrifugal blood separator are used; Blood through the blood taking needle collection mixes with the anti-freezing liquid that perforator I is linked into the anti-freezing liquid pipe at three way cock I; Form anticoagulation; Adopt through blood that defeated pipe I gets into blood filter, blood is adopted defeated pipe II, blood tube, cone joint, blood separation cup, in the blood separation cup, isolate blood plasma and hemocyte.Blood plasma overflows and gets into plasma collection pipe, plasma collection bag.When the plasma collection end, blood separation stops, and blood separator is closed blood and adopted defeated pipe II; Open the displacement liquid pipe, the displacement liquid that substitutes blood plasma gets into the blood separation cup through perforator II, displacement liquid pipe, three way cock's II, blood tube, after the displacement liquid magnitude of recruitment reaches setting value; Displacement liquid stops to replenish, and blood separator is opened blood and adopted defeated pipe II, closes the displacement liquid pipe; The blended hemocyte of all and displacement liquid in the blood separation cup is fed back human body, accomplish a circulation plasmapheresis process.According to instructions for use, repeat said process, can accomplish whole replacement therapy of blood plasma process.
This utility model possesses following superiority:
1, precise control property: the displacement liquid bag can obtain the weight that displacement liquid replenishes infusion constantly through being suspended on the blood separator electronic scale, makes infusion amount more accurate.
2, mixing uniformity: displacement liquid gets into blood separation cup bottom through the displacement liquid pipe and mixes the back feedback with hemocyte, and it is more even that displacement liquid is mixed with hemocyte.
3, convenience is installed: the collection of discarded blood plasma is taken over through plasma collection bag bag WEILIAN and is realized that loading amount increases, and is installed in the control of not weighing on the machine hook, does not need frequent change, and it is more convenient to use.
