Abstract
The utility model relates to a connecting bag special for matched plasma exchange, filtration and adsorption treatment. The connecting bag comprises a plasma storage bag and is characterized in that: the upper end of the plasma storage bag is connected with an upper catheter and an upper extension tube respectively; the lower end of the plasma storage bag is connected with a lower catheter and a lower extension tube respectively; the upper catheter is connected with a vein loop pipe of a blood filtering device through an inlet joint; the lower catheter is connected with an artery loop pipe of the blood filtering device through an outlet joint; the upper extension tube is connected with the outlet of a blood perfusion device through a dialysate connector; the lower extension tube is connected with an ordinary infusion tube; the upper catheter and the lower catheter are single-needle double-cavity catheters for hemodialysis; and the upper catheter, the lower catheter, the upper extension tube and the lower extension tube are movably sleeved with a clamp respectively. After the technical scheme is adopted, the plasma storage bag is taken as a junction, so that two purification devices are connected in parallel and can run independently without influencing each other.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, specifically belongs to a kind of and is used to match the special use that plasmapheresis filters adsorbing therapy and connects bag.
Background technology
In recent years, the blood purification technology is widely used in the treatment of liver failure, and is defined as abiotic type artificial liver support system.Clinical method commonly used has uniting of plasmapheresis, blood (or blood plasma) absorption, hemodiafiltration, hemofiltration and said method etc., and more the therapeutic alliance with various blood purification methods is its development trend.Blood plasma absorption equipment commonly used can adopt the immunoadsorption machine, and its process is specially: by the plasma separator separated plasma, isolated blood plasma is flowed into the absorption of blood plasma adsorption column (or perfusion device) promoting the circulation of blood slurry.Hemofiltration adopts equipment for continuous renal replacement therapy usually, uses transfusion filters and carries out.Two kinds of apparatus for purifying blood all are separate equipment, can not implement treatment simultaneously to a patient usually.Just attempting a kind of novel blood purification system-pairing blood plasma filtration absorption from foreign scholar in 2003, this system will carry out hemodiafiltration after the blood plasma absorption again, plasma separator is connected in placed in-line mode with filter for blood dialysis, be whole blood and implement treatment, this just needs two equipment to turn round simultaneously, one warning stall, another stops transport thereupon, clinical manipulation is very difficult, and the blood volume of extracorporeal circulation is 600ml at least, critical patient often is difficult to tolerance, thereby makes this technology so far can not be at clinical application after proposing in 2000.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of pairing plasmapheresis simple in structure, that two kinds of purification methods are carried out simultaneously to filter the special-purpose bag that connects of adsorbing therapy.
For solving the problems of the technologies described above, this utility model by the following technical solutions:
The pairing plasmapheresis filters the special-purpose bag that connects of adsorbing therapy, comprise the blood plasma reservoir bag, it is characterized in that: described blood plasma reservoir bag upper end is connected with upper conduit and last prolongation pipe respectively, the lower end of described blood plasma reservoir bag is connected with downcomer and downward long tube respectively, described upper conduit is connected with the vein loop pipe of hemofiltration device by inlet union, described downcomer is connected with the tremulous pulse loop pipe of hemofiltration device by outlet connection, described upward prolongation pipe is connected with the delivery outlet of blood perfusion device by dialysate connector, and described downward long tube is connected with the common transfusion pipe.
Described upper conduit and downcomer adopt hemodialysis single needle double channel catheter.
Described upper conduit, downcomer, go up and prolong on pipe and the downward long tube all that activity is with a clip.
Described connection bag all adopts medical PVC to make.
After adopting above technical scheme: with the blood plasma storage bag is hinge, makes two kinds of purifiers connect with the form of parallel connection, can be so that two kinds of purifiers independent operation simultaneously, and can not influence each other again.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the pairing plasmapheresis filters the special-purpose bag that connects of adsorbing therapy, comprise blood plasma reservoir bag 1, blood plasma reservoir bag 1 is a kind of blood plasma reservoir bag of special use, blood plasma reservoir bag 1 is 1000 milliliters of capacity, blood plasma reservoir bag 1 upper end is connected with upper conduit 2 and last prolongation pipe 3 respectively, the lower end of blood plasma reservoir bag 1 is connected with downcomer 4 and downward long tube 5 respectively, upper conduit 2 can be connected with the vein loop pipe of hemofiltration device by inlet union 6, downcomer 4 can be connected with the tremulous pulse loop pipe of hemofiltration device by outlet connection 7, last prolongation pipe 3 can be connected with the delivery outlet of blood perfusion device by dialysate connector 8, and downward long tube 5 is connected with the common transfusion pipe.Top inlet union 6, outlet connection 7 and dialysate connector 8 all adopts the joint of unification of the motherland standard universal dialysis usefulness, and its locking mechanism can adopt screw thread, and joint head tapering can adopt 6%, connects bag and all adopts medical PVC to make.Upper conduit 2, downcomer 4, go up and prolong on pipe 3 and the downward long tube 5 all that activity is with a clip 9, clip 9 can adopt the general curative clip, tightens various conduits by clip, makes conduit can't pass through liquid.
The concrete work process of this utility model:
(1) carry out about 2 hours plasmapheresis earlier, promptly use the immunoadsorption machine to carry out plasmapheresis, the blood plasma after will separating then enters the blood plasma reservoir bag by the plasma perfusion device, and the blood plasma part in the blood plasma reservoir bag is mixed with hemocyte in the feedback body.
(2) another part carries out blood plasma repeatedly by last downcomer and hemofiltration device and filters.
Like this, two top apparatus for purifying blood can carry out simultaneously, are hinge with the blood plasma storage bag, make two kinds of purifiers connect with the form of parallel connection, can be so that two kinds of purifiers independent operation simultaneously, and can not influence each other again.
Claims (4)
1. the pairing plasmapheresis filters the special-purpose bag that connects of adsorbing therapy, comprise blood plasma reservoir bag (1), it is characterized in that: described blood plasma reservoir bag (1) upper end is connected with upper conduit (2) and last prolongation pipe (3) respectively, the lower end of described blood plasma reservoir bag (1) is connected with downcomer (4) and downward long tube (5) respectively, described upper conduit (2) is connected with the vein loop pipe of hemofiltration device by inlet union (6), described downcomer (4) is connected with the tremulous pulse loop pipe of hemofiltration device by outlet connection (7), described upward prolongation pipe (3) is connected with the delivery outlet of blood perfusion device by dialysate connector (8), and described downward long tube (5) is connected with the common transfusion pipe.
