Description
Technical field
The application belongs to field of medical technology, specifically, being related to a kind of plasma exchange harvester.
Background technology
PE plasmapheresis refers to outside the blood lead body by patient, by membrane plasma separation method by the blood plasma of patient
It separates and discards from whole blood, then supplement the displacement liquids such as fresh frozen plasma or the human serum albumin of equivalent, in this way
To remove the various metabolic toxicities and virulence factor of patient's body, to reach therapeutic purposes.It is common in plasma exchange at present to set
It changes liquid and is finished alarm, since plasma exchange liquid is fresh frozen plasma, replacement amount 3-5L, normal plasma flow is 20-30ml/
Min, and 100-150ml/ bags of blood plasma specification, general 4-10min will replace a plasma bags.If nurse is ignoring blood at this time
Flow is starched, can cause displacement liquid to be finished and cause to alarm, causes to replace liquid pump stalling.It also results in displacement liquid and evacuates venous chambers page
Face reduces or enters air, and blood pump is caused to stall, and increases the risk of plasma separator blood coagulation.
Invention content
In view of this, technical problems to be solved in this application are to provide a kind of number for avoiding frequently replacing plasma bags
Plasma exchange harvester.
In order to solve the above-mentioned technical problem, the application has opened a kind of plasma exchange harvester, including：Displacement liquid connects
Head, level-one three-way connection, two level three-way connection, three-level three-way connection, plasma bags connector；The displacement liquid connector and level-one three
One end of pass joint is connected to by woven hose, and the other both ends of level-one three-way connection pass through woven hose and two level three-way connection respectively
One end is respectively communicated with, and the other both ends of two level three-way connection are connected to one end of three-level three-way connection respectively, three-level three-way connection
Other both ends respectively pass through woven hose connect plasma bags connector；
It is provided with air bleeding valve between plasma bags connector and three-level three-way connection.
Further, plasma exchange harvester as described above, the connection between air bleeding valve and three-level three-way connection
Individual event control folder is provided on pipeline.
Further, plasma exchange harvester as described above is connected with anti-between individual event control folder and air bleeding valve
Solidifying agent pipeline.
Further, plasma exchange harvester as described above is controlled in individual event and is set between folder and three-level three-way connection
It is equipped with pressure detector.
Compared with prior art, the application can be obtained including following technique effect：
The application extracts blood plasma mode using in parallel, improves the capacity of displacement liquid per hour, avoids frequently replacing blood plasma
The number of bag, reduces and alarms caused by displacement liquid is finished, while reducing the risk of plasma separator blood coagulation.
Description of the drawings
Attached drawing described herein is used for providing further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please do not constitute the improper restriction to the application for explaining the application.In the accompanying drawings：
Fig. 1 is the structural schematic diagram of the embodiment of the present application.
Specific implementation mode
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments, thereby how the application is applied
Technological means solves technical problem and reaches the realization process of technical effect to fully understand and implement.
When due to replacing blood plasma to patient, need that the blood plasma how much measured replaced to be there are different demands according to different patients
, in order to avoid being in the presence of that (for example a patient only needs to replace the blood plasma of 250ml, and rule of blood plasma band for blood plasma waste
If lattice are 500ml, just will appear a large amount of waste), the specification of plasma bags is 100-150ml/ bags at present, and needs are set
For the big patient of the amount of changing, it is easy for occurring surprisingly, for example nurse is ignoring plasmaflux, can cause displacement liquid to be finished and make
At alarm, cause to replace liquid pump stalling.It also results in displacement liquid to evacuate the reduction of the venous chambers page or enter air, and blood pump is caused to stop
Turn, increase the risk of plasma separator blood coagulation, in order to avoid problem above, the application is made using intravenous nutrition bag connecting tube
With principle, a kind of connecting tube of 8 connector is designed, 8 bags of blood plasma, about 800-1600ml, when plasmaflux is in 20- can be connected simultaneously
When 30ml/min, 40-55min is needed to replace a plasma bags.In conventional replacement amount 3-5L, it is only necessary to replace plasma bags 3-4 times, effectively
It avoids displacement liquid and is finished and cause to alarm, cause to replace liquid pump stalling and displacement liquid evacuates the venous chambers page and reduces or enter empty
Gas, and blood pump is caused to stall, reduce the risk of plasma separator blood coagulation.
Fig. 1 is the structural schematic diagram of the embodiment of the present application, as shown in Figure 1, plasma exchange provided by the embodiments of the present application is adopted
Acquisition means, including：Displacement liquid connector 4, level-one three-way connection 7, two level three-way connection 6, three-level three-way connection 5, plasma bags connect
