Abstract
The utility model relates to a disposable leucocyte-depleted single blood component separator which is mainly used to collect and supply leucocyte-depleted platelet for clinical patients. The disposable leucocyte-depleted single blood component separator consists of a blood component separator, a leucocyte-depleted filter, a transfer bag, a platelet constant-temperature storage bag and the like, and is characterized in that all components are connected in a sealing way, to form a sealed disposable medical instrument; the leucocyte-depleted filter is directly connected with the transfer bag of the blood component separator; and the platelet constant-temperature storage bag is connected with a sample bag. The disposable leucocyte-depleted single blood component separator automatically filters leucocyte from the collected blood components, has quite high efficiency, minimizes transfusion reaction and protects the health of blood donors.
Description
Technical field
This utility model relates to the separator of a kind of collection, the leukocytic blood component of preparation removal, is a kind of medical consumption utensil of disposable use that the blood constituent machine is adopted, leukocytic removal is one that collects.
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 had the blood that will gather by the blood component separator blood component to be separated, but contained a large amount of leukocyte in the blood composition of being gathered, too high leukocyte is sneaked into, and will cause the generation of nonhemolytic transfusion reaction, increases the blood transfusion risk.Also there is not at present a kind of disposable use blood component separator that blood component collection and leucocyte removal are that one efficient separates automatically, collection efficiency is higher, clinical safety is used that collects.
Summary of the invention
In view of the present situation of above-mentioned blood component separator, the purpose of this utility model provide a kind ofly collect blood component collection, leukocytic removal is the efficient disposable use blood component separator of one.
The disposable use leucocyte-removing list blood sampling composition separator that this utility model provides can be realized above-mentioned purpose.
This utility model is made of blood component separator, transfering bag, leucocyte-removing filter, exhaustor, keep sample bag, platelet room temperature storage bag and transporting hose, a plurality of only anchor clamps of liquid function that are used for are housed on the transporting hose, it is characterized in that the leucocyte-removing filter is directly connected on the transfering bag of blood constituent separator.
For the ease of preserving composition blood and be convenient to the sampling inspection of blood composition, and avoid blood contamination, can on the platelet room temperature storage bag of disposable use leucocyte-removing list blood sampling composition separator, connect the bag that keeps sample;
For operation readiness, assurance separation process safety, pollution-free, nothing is leaked, the all constituents of described disposable use leucocyte-removing list blood sampling composition separator all adopt be tightly connected complete, form the medical appliance of complete closed, need not sterilization and be connected, open packing and can use with plug-in mounting.
This disposable use leucocyte-removing list blood sampling composition separator is mainly used in the platelet of gathering and leucocyte-removing being provided, and uses for clinical patients, and its construction features and operation principle are as follows:
The three parts that mainly are divided into of the present utility model:
One, blood component collecting part
The disposable use blood component separator that is used by existing market carries out hematoblastic collection, enters in the transfering bag after collection is finished, and collects in the platelet room temperature storage bag.Whole process is carried out in a complete airtight environment, and is efficient, safety.
Two, leukocyte depletion part
The platelet of gathering directly need be removed leukocytic composition blood by the transporting hose of transfering bag lower end and import the leucocyte-removing filter, pipeline by the bag tail, utilize self-gravity action, carry out leukocytic removal through the leucocyte-removing filter, after finishing, get rid of unnecessary gas in the transfering bag by the exhaust hose in parallel, finish leukocytic removal in the composition blood with filter;
Three, the storage of composition blood
Finishing platelet after the filtration finally enters into platelet room temperature storage bag and stores, be equipped with clinical use, the bag that keeps sample that is connected a threeway with platelet room temperature storage bag jointly can be avoided contamination of products, the sampling inspection that is used to preserve composition blood He is convenient to the blood composition.
The disposable use leucocyte-removing of basis list blood sampling composition separator with said structure characteristics, collection blood component collection and leucocyte removal are one, efficient separation automatically has simple operation, higher, the clinical characteristics safe in utilization of collection efficiency.
Description of drawings
Fig. 1 is the structural representation according to medical appliance of the present utility model.
The specific embodiment
Embodiment 1
This disposable use leucocyte-removing list blood sampling composition separator is made of blood component separator 1, transfering bag 2, leucocyte-removing filter 3, exhaustor 4, anchor clamps 5,5 ', the bag 6 that keeps sample, platelet room temperature storage bag 7.The transporting hose of transfering bag 2 upper ends directly with blood component separator 1 on T type threeway a directly be communicated with, the transporting hose of lower end has assembled anchor clamps 5 ' back and directly has been connected with leucocyte-removing filter 3 inputs, the outfan of leucocyte-removing filter 3 links to each other with platelet room temperature storage bag 7 with the bag 6 that keeps sample by threeway, simultaneously, the leucocyte-removing filter is in parallel with exhaustor 4 by threeway.This utility model separator is equipped with a plurality of liquid stopping clamp tools 5 according to functional requirement on transporting hose.
The above description of being done in conjunction with this utility model embodiment does not constitute any qualification to protection domain of the present utility model.Those skilled in the art can make various changes on basis of the present utility model, these change all should think and fall within the protection domain that this utility model claim limited.
Claims (3)
