Blood-taking device: for the passage that blood of human body is drawn.
Separate cup: the critical piece of blood component separation, when itself and the supporting separating blood composition of seperator, rotating speed is 5500r/min.
Product-collecting bag: for final hematoblastic collection.
Blood plasma transfering bag: for interim collection of each circulation of blood plasma when the separating blood composition.
Degassing bag: for each circulation time by the collection of the filtrated air in separator system.
Compared with prior art, the beneficial effects of the utility model: all constituents that this utility model improves the device of platelet collection rate all adopt be tightly connected complete, formed totally enclosed medical appliance, clinical use safety, guarantee separation process safe, pollution-free, without leaking, have simple operation, collection efficiency high, without sneaking into the advantage that other does not need blood component.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model improves the device of platelet collection rate.
In figure: 1-blood component separator, the rich composition platelet of 2-transfering bag, 3-platelet collect tube road, 4-enters blood vessel road, 5-connecting hose, the threeway of 6-T type, 7-blood-taking device, 8-separate cup, 9-degassing bag, 10-product-collecting bag, 11-blood plasma transfering bag, 12-blood taking needle, 13-anticoagulant injection device, 14-four-way, 15-multichannel integration pump card.
The specific embodiment
Below in conjunction with specific embodiment, this utility model is further described.
Disclosed all features in this description, or the step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can combine by any way, unless narration especially, all can be replaced by other equivalences or the alternative features with similar object,, unless narration especially, an embodiment in a series of equivalences of each feature or similar characteristics.
As shown in Figure 1, the device that this utility model improves platelet collection rate comprises blood component separator 1, rich composition platelet transfering bag 2 and T-shaped threeway 6 and four-way 14, what one end of described T-shaped threeway 6 connected blood component separator 1 enters blood vessel road 4, platelet collect tube road 3, the three ends that one end connects blood component separator 1 are connected with rich composition platelet transfering bag 2 by connecting hose 5.Described blood component separator 1 comprises blood-taking device 7, separate cup 8, product-collecting bag 10 and blood plasma transfering bag 11.Blood-taking device 7 comprises blood taking needle 12 and the anticoagulant injection device 13 that is positioned at leading portion, and blood taking needle 12 contacts with human body, by syringe needle, immediately takes a blood sample.In order to prevent the new blood coagulation gathering, therefore by anticoagulant injection device, inject anticoagulant, will by flexible pipe, export through the fresh blood of sneaking into after anticoagulant.The outfan of blood-taking device 7 is connected with separate cup 8 by flexible pipe, and blood carries out separation in separate cup.Between blood-taking device 7 and separate cup 8, be provided with multichannel integration pump card 15, multichannel integration pump card 15 is clamps that play fixing effect that arrange in order to prevent soft tube winding.Between blood-taking device 7 and separate cup 8, be provided with by-pass valve control.On the flexible pipe of separate cup 8 rear ends, be provided with a degassing bag 9, this degassing bag 9 in order to get rid of in advance ducted air.The outfan of separate cup 8 connects platelet collect tube road 3 by four-way 14, and other two terminations of four-way are respectively by hose connection product-collecting bag 10, blood plasma transfering bag 11 and T-shaped threeway 6.Blood enter separate cup separation afterwards the blood plasma of light density first by four-way, pass through connecting hose and enter in blood plasma transfering bag, when seperator monitors pipeline and has platelet, on seperator, control the valve closing of blood plasma transfering bag, platelet enters in product-collecting bag 10 and collects through four-way 14, when seperator monitors on pipeline PC and reduces, on seperator, control the valve closing of Thrombocyte collecting bag 10, residue contains other compositions such as hematoblastic blood plasma and flow in rich composition platelet transfering bag 2 by four-way 14 and T-shaped threeway 6, now, separate cup stops separating blood composition, blood plasma in erythrocyte in separate cup and blood plasma transfering bag 11 is entered to pipeline 4 by integration pump card 15 and be also defeated by blood donor, complete a circulation, second circulation starts seperator has hematoblastic rich composition blood plasma by entering blood vessel road 4, to be pumped into and in separate cup 8, to carry out the separated of blood component together with the anticoagulated whole blood of drawing from human body the content in rich composition platelet transfering bag 2 by integration pump card 15, at this moment the PC in separate cup 8 pumps into because of hematoblastic from rich composition platelet transfering bag 2 that to compare in the first circulation separate cup PC large, platelets gathering program subsequently and the first circulation are just the same, and the PC gathering will significantly improve, so repeatedly gathering resulting PC and purity can be largely increased, until reach the target collection capacity that seperator arranges.
All constituents all adopts and is tightly connected completely, has formed totally enclosed medical appliance; By supporting the use with blood component seperator, complete hematoblastic separation and collection, have that other composition of blood is sneaked into less, platelet collection efficiency is high, and reduce to greatest extent transfusion reaction, protection blood donor's health.
Operation principle of the present utility model:
By the disposable use blood component separator using in the market, carry out the every circle collection of platelet, every circulating collection hematoblastic initial with finish before utilize related valve will contain to enrich hematoblastic blood component and collect in advance in rich composition platelet transfering bag, and the higher platelet of reservation stage casing purity is collected in product-collecting bag.Then, when the next one circulates separated platelet, the hematoblastic blood component that is rich in rich composition platelet transfering bag is pumped into and in separate cup, carries out separated, Platelet Concentrate together with whole blood.Now, the PC of separate cup is high compared with PC in whole blood, when reaching the collection valve value of machine setting, carries out automatic hematoblastic collection procedure.Collection procedure still by collect hematoblastic initial with finish before, again will contain and enrich hematoblastic blood component and collect in advance in rich composition platelet transfering bag, and retain the higher platelet of stage casing purity, collect in product-collecting bag, so iterative cycles carries out separation, concentrates and collects platelet until complete the hematoblastic collection established standards of setting.This kind of method can fully improve the hematoblastic collection rate of the every circulation of platelet, and can well get rid of sneaking into of other blood component.Whole process is carried out in a complete airtight environment, efficient, safety.
Through experimental verification, through this utility model, can reach efficient automatically separated, have simple operation, collection efficiency high, without sneaking into other unwanted blood component, the feature of clinical use safety.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
