Abstract
A disposable soft bag leukoreduced blood collection and transfusion device is mainly used for providing leukoreduced PRBC (packed red blood cell) to a clinical patient, and comprises a puncture needle, a blood collection bag, blood storage bags, a soft bag leukopheresis filter, a preserving fluid bag and a transmitting hose, wherein, all components adopt sealing connection; the blood collection bag is connected with the soft bag leukopheresis filter and the blood storage bags respectively; the soft bag leukopheresis filter is communicated with the preserving fluid bag; an exhaust hose is connected with the soft bag leukopheresis filter in parallel; and the exhaust hose is communicated with the preserving fluid bag. The PRBC, blood plasma and platelet are separated from whole blood in the blood collection bag after centrifugation; the blood plasma and the platelet are respectively transferred to the respective blood storage bags and used as subsequent requirements such as the collectionof platelet; remaining PRBC enters the soft bag leukopheresis filter through the hose; after white blood cells are filtered from the remaining PRBC through the soft bag leukopheresis filter by utilizing self-gravity, the remaining PRBC passes through the exhaust hose which is connected with the soft bag leukopheresis filter in parallel, so as to remove excess gas in the preserving fluid bag; andthen the PRBC with no white blood cells can be obtained.
Description
Technical field
This utility model relates to the medical consumption utensil of a kind of disposable use, and the blood exchange transfusion set that adopts of leukocytic blood component is removed in particularly a kind of collection, preparation.
Technical background
At present, human body is donated blood and is still the main source of medicinal blood.When donating blood, often only need certain or certain several specific blood component, for example blood plasma, platelet, erythrocyte or leukocyte etc., and other compositions can feed back to the blood donor, to avoid the waste of blood resource.Therefore, donate blood technology in the modern times, adopt blood component to gather isolating method more, promptly the separation of whole blood of being gathered out by the blood donor becomes different compositions, and the composition that needs is taken out, then remaining composition blood is fed back to the blood donor.
Now there has been the blood that to gather blood component to be screened by the leucocyte-removing filter, but because at first whole blood is gone white filtration, so cause blood component platelet important in the blood to be lost in the white filter, caused the significant wastage of blood.Existing market has only the leucocyte-removing filter of duricrust class, does not have also to put into after can will remove white filter and the blood bag be connected that centrifuge is centrifugal removes white filter.
Summary of the invention
Present situation in view of above-mentioned leukocyte depleted blood bag, the purpose of this utility model provides a kind ofly can be put into centrifuge with the blood bag and carry out centrifugal, can not break under the action of centrifugal force being subjected to, and in autoclaving and packing, can not make the be squeezed leucocyte-removing filter of distortion of corresponding flexible pipe in the blood bag.
The disposable use leucocyte-removing that this utility model provides is adopted the blood exchange transfusion set and can be realized above-mentioned purpose.
The soft bag of this disposable use goes the white blood exchange transfusion set of adopting, comprise that puncture needle, blood taking bag, storage blood bag, soft bag remove white filter, preservation liquid bag and transporting hose, a plurality of only anchor clamps of liquid that are used for are housed on the flexible pipe, all constituents all adopts and is tightly connected, form the medical appliance of complete closed, it is characterized in that blood taking bag goes white filter to link to each other with storage blood bag with soft bag respectively, soft bag goes white filter to be communicated with preservation liquid bag, soft bag removes an exhaust hose in parallel on the white filter, and this exhaust hose is communicated with preservation liquid bag.
Above-mentioned leucocyte-removing filter is by PVC film, upper impression, leucocyte-removing filter membrane, lower impressions and import and export mixes, and the leucocyte-removing filter membrane also forms two cavitys up and down with the PVC thin film heat seal that covers on it, is communicated with import and outlet respectively.
The soft bag of this disposable use leucocyte-removing is adopted the blood exchange transfusion set and is mainly used in collection and provides the Red Blood Cells Concentrate of leucocyte-removing to use for clinical patients.
For operation readiness, assurance filter process safety; pollution-free, nothing is leaked; the all constituents that the soft bag of this disposable use leucocyte-removing is adopted the blood exchange transfusion set all adopt be tightly connected complete; form the medical appliance of complete closed; leukocyte in the Red Blood Cells Concentrate that efficient filtering is gathered need not sterilization and is connected with plug-in mounting, opens packing and can use; can keep the platelet in the blood to greatest extent and reduce transfusion reaction, protection blood donor's health.
Its construction features and operation principle are as follows:
This utility model mainly is divided into three parts:
One, blood collection and centrifugalize part
By puncture needle whole blood is introduced in the blood taking bag, will be put in order the tool product after finishing and be positioned over centrifugalize in the centrifuge.Whole process is carried out in efficient, safe, an airtight fully environment.
Two, the transfer of composition blood
Blood plasma in the blood taking bag of centrifugal back and platelet composition are transferred in the storage blood bag as follow-up required as collecting platelet.
Three, leukocyte depletion part
The leucocyte-removing filter is by PVC film, upper impression, leucocyte-removing filter membrane, lower impressions and import and export mixes, and the leucocyte-removing filter membrane also forms two cavitys up and down with the PVC thin film heat seal that covers on it, is communicated with import and outlet respectively.
Blood taking bag is separated the remaining Red Blood Cells Concentrate in back enter into soft bag leucocyte-removing filter by flexible pipe, utilize self-gravity action, through leucocyte-removing filter filtering leukocyte, after finishing, get rid of unnecessary gas in the preservation liquid bag by the exhaust hose in parallel, finish leukocytic removal in the Red Blood Cells Concentrate with filter.
The soft bag of the disposable use of basis leucocyte-removing with said structure characteristics is adopted the blood exchange transfusion set, has simple operation, higher, the clinical characteristics safe in utilization of collection efficiency.

The specific embodiment
Embodiment 1
The soft bag of this disposable use leucocyte-removing is adopted the blood exchange transfusion set, comprises that puncture needle 1, blood taking bag 2, storage blood bag 3, soft bag remove white filter 4, preserve liquid bag 5, are equipped with a plurality of only anchor clamps 6 of liquid function that are used on the flexible pipe.All constituents all adopts and is tightly connected, form the medical appliance of complete closed, blood taking bag 2 goes white filter 4 to link to each other with the threeway of storage blood bag 3 front ends with soft bag respectively by a threeway, soft bag goes white filter 4 to be communicated with preservation liquid bag 5, soft bag goes to white filter 4 rear and front ends respectively to be provided with a threeway, cross-over connection has with soft bag and removes white filter 4 exhaust hose 7 in parallel in two threeways, and this exhaust hose 7 is communicated with preservation liquid bag 5.
