Description
Technical field
This utility model relates to a kind of medical treatment device, and particularly erythrocytic single device for picking is removed in a kind of and supporting use of blood constituent separation equipment.
Background technology
Modern hematologic disease studies have shown that the root that causes polycythemia vera is that RBC number surpasses normal value in the peripheral blood, and hemoglobin, packed cell volume be corresponding increasing also, belongs to the paraplasm neoplastic disease of a kind of myeloid tissue.Therapeutic Method is to make red blood cell mass by physics and medicine, total blood volume approaches or replys normal, physical method is to adopt the mode of venesection to carry out, can reduce erythrocyte and whole blood volume quickly and effectively, improve symptom, but the blood-letting frequency is excessive, easily lose antithrombase in a large number, cause hypercoagulability, form hemorrhage and thrombotic danger, to old or the more difficult operation of patient of cardiovascular disease is arranged, complication is many, the blood cell separator of using external import carries out the erythrocyte list to the patient and adopts art, can reduce erythrocyte number rapidly, improve clinical symptoms, prevention thrombosis.Therapeutic erythrocyte list is adopted art except the advantage with bloodletting, feed back most of blood plasma when being implemented in separating red corpuscle, can reduce losing of plasma protein, thrombin, replenish a certain amount of colloid and crystalloid fluid simultaneously, reach and reduce patient's red blood cell volume load, dilute blood, the high glutinous state of alleviation, clinical use proves, erythrocyte, hemoglobin, packed cell volume significantly reduce before and after separating, leukocyte and platelet descend not obvious before and after separating, but import equipment and consumptive material are expensive, and often patient's economic pressures for the treatment of are big.
The equipment that domestic prior art is separated blood constituent and consumptive material development have entered a new height, on safety, reliability near foreign level.But erythrocyticly singly adopt equipment and consumptive material also is in the starting stage at removing separately.
Summary of the invention
In view of domestic prior art has been advanced near foreign level equipment and consumptive material development that blood constituent separates, but separately at removing the erythrocytic present situation that equipment and consumptive material also are in the starting stage of singly adopting, to be that design is a kind of the time remove erythrocyte for treatment to the purpose of this utility model, carry out simultaneously blood plasma feed back synchronously operation ease be provided, make things convenient for erythrocyte to gather after, feed back residue erythrocyte process and replenish colloid and crystalloid fluid, blood volume balance when keeping treatment, the device of reduction packed cell volume and blood viscosity.
This removing formula erythrocyte list device for picking, comprise four-way, the blood plasma transfering bag, the blood separation cup, the erythrocyte collecting bag, and by blood taking needle, liquid stopping clamp, sampler, the perforator I, biofilter, blood filter, the collection sampling slip that the pressure monitor joint constitutes, the anticoagulant branch road, three branch roads of blood filtration and pressure sensing, four-way goes out end and connects sampling slip respectively, the anticoagulant branch road, three branch roads of blood filtration and pressure sensing, it is characterized in that the blood plasma transfering bag has up and down, export structure, blood filter goes out between end and the blood pump line threeway I and threeway II are set, arrange by the threeway III between blood separation cup and the blood plasma transfering bag, the liquid that perforator II and transporting hose constitute replenishes branch road, the end of going into of threeway I exports and links to each other respectively with under blood filter and the blood plasma transfering bag, the threeway II is gone into to hold to connect respectively the threeway I and is gone out to hold and the erythrocyte collecting bag, the threeway II goes out end and links to each other with blood separation cup entrance through pump line, the threeway III is gone into end and is connected with the perforator II with the transparent detection flexible pipe of blood separation cup outlet connection respectively, and the threeway III goes out end and is connected with blood plasma transfering bag upper inlet.
The utlity model has advantage simple in structure, easy and simple to handle, that consumables cost is lower.The blood plasma transfering bag is designed to import and export structure up and down, liquid is replenished branch road inserts technical measures between blood separation cup and the blood plasma transfering bag entrance, the convenient back feedback process of gathering is replenished and the colloid of removing erythrocyte equivalent and crystalloid fluid blood volume balance when keeping treatment, realization reduces the packed cell volume of patient body and the therapeutic purposes of blood viscosity, provides operation ease for carrying out the blood plasma feedback in the treatment collection removing erythrocyte process simultaneously.
Operation principle of the present utility model is as follows:
Removing formula erythrocyte list device for picking of the present utility model and blood separator are used, when the blood of blood taking needle collection enters four-way connection, the anti-freezing liquid that inserts with perforator mixes, form anticoagulation, at this moment, pressure monitor joint monitoring blood pressure, blood separator is adjusted peristaltic pump speed automatically, and anticoagulated blood enters the blood separation cup by blood filter, separate cup joint and carries out centrifugalize.Isolate interior light outer heavy blood plasma, tunica albuginea, erythrocyte layer centered by the separate cup axle at separate cup, plasma fraction after the lightest plasma fraction overflows by the blood plasma overflow channel, enters blood plasma transfering bag by upper inlet at the axis part that leans on of separation chamber.Along with the separate cup that constantly pumps into of anticoagulated blood separates, when the blood constituent in the transparent detection flexible pipe be detected overflow a small amount of erythrocyte after, blood collection stops, machine is adjusted the flexible pipe switching programme, open blood plasma transfering bag gateway and erythrocyte collection flexible pipe up and down respectively, close flexible pipe between threeway I and the threeway II, utilize gravitational method to feed back blood plasma and the tunica albuginea composition that the incipient stage overflows, carry out simultaneously the interior erythrocyte of blood pump feedback separate cup synchronously and enter the erythrocyte collecting bag, after outlet feeds back the blood plasma end under the blood plasma transfering bag, air is detected by machine in the flexible pipe, machine cuts out automatically under the blood plasma transfering bag and exports, weighed the erythrocyte collecting bag of weight by blood separator after obtaining weight, opening entry blood pump revolution, after erythrocyte is collected and is finished, open flexible pipe and the additional branch road of liquid between threeway I and the threeway II, close erythrocyte and collect flexible pipe, the peristaltic pump revolution carries out colloid and crystalloid fluid by same number of revolutions and replenishes when collecting according to erythrocyte, after the feedback revolution reaches, closing liquid replenishes branch road, after separate cup is cleared, begin the collection of next circulation, separate, collect, the feedback process, collect total amount up to erythrocyte and reach setting value, termination routine.Like this, only gathering needs the red blood cell component removed, and blood plasma, tunica albuginea feed back patient fully, replenishes colloid and crystalloid fluid with the erythrocyte equivalent of removing simultaneously, and patient's blood volume is not changed, and more can guarantee therapeutic process safety.
The blood separation cup can be selected the low capacity of different size or the separating plasma cup of normal capacity, and patient's extracorporeal circulation of blood amount is further guaranteed safety when being conducive to reduce treatment.
