Description

Single blood sampling cell separator of disposable use band biofilter

Technical field

This utility model relates to the medical consumption utensil of a kind of disposable use, and particularly a kind of is that carrier carries out the band biofilter list blood sampling cell separator that the centrifugal blood formula is separated, collected blood component with soft bag.

Background technology

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.

The single blood sampling cell separator of existing disposable use great majority are Open architecture, and because of need puncture bag of saline and anticoagulant bag, so be open, the probability that is polluted is bigger during use, and the platelet of collection can only be preserved 24 hours at normal temperatures.At present domestic also do not have and the supporting use of blood component seperator, can carry out efficient separation automatically, the blood donor is fed back safe single blood sampling cell separator.

Summary of the invention

Present situation in view of above-mentioned blood cell separator, the purpose of this utility model provides a kind of and the supporting use of blood component seperator, and the blood donor is fed back safety, can carry out efficient separation, the higher disposable use band biofilter list blood sampling cell separator of collection efficiency automatically to the blood component of being gathered.

The disposable use band biofilter list blood sampling cell separator that this utility model provides is realized above-mentioned purpose by following structure:

This disposable use band biofilter list blood sampling cell separator, disposable use band biofilter list blood sampling cell separator, comprise back the blood exchange transfusion set, blood filter, transfering bag, the blood plasma transfering bag, degassing bag, dropping funnel perforator I-III, whole blood pump line I-II; little pump line; pressure transducer I-II; assembling box; air filter kettle; multi-lumen tube; sampler bag; collecting bag; separation bag and hemostix; it is characterized in that having biofilter I-III; the input of biofilter I-III is connected to corresponding perforator I-III lower end; biofilter I outfan connects blood filter upper end and degassing bag respectively; biofilter II output termination pressure monitor I, the little pump line of biofilter III output termination; The blood filter upper end connects degassing bag and biofilter I outfan respectively, and two interfaces link to each other with time blood exchange transfusion set with pressure transducer II respectively in addition; Have four flexible pipes on the separation bag, one links to each other with air filter kettle, and one is connected with collecting bag through multi-lumen tube with after whole blood pump line II is connected, other two be converted to one through threeway and enter multi-lumen tube after pressure transducer II links to each other with blood filter; Two flexible pipes are arranged on the collecting bag, and one links to each other with the blood plasma transfering bag with transfering bag respectively by multi-lumen tube, and one links to each other with separation bag by whole blood pump line II; Air filter kettle input links to each other with whole blood pump line I through pressure transducer I, and outfan links to each other with separation bag through multi-lumen tube; Multi-lumen tube is fixed on entire belt biofilter list blood sampling cell separator on the composition blood system disembarks by turret head, and each ingredient and connector and transporting hose junction all adopt medical glue sealing bonding, form sealed self-circulation system.

The construction features and the operation principle of critical piece of the present utility model are as follows:

After the separator assembling is finished, need with normal saline and anticoagulant initialization, its purpose is exactly the whole process of imitating collection, and flushing line, and deaeration makes the pressure of system reach balance.The operation of puncturing after the beginningization, in running, the anticoagulant whole blood is pumped in the rotating separation bag under the effect of whole blood pump, and the isolating first step of blood component occurs in separation bag; After whole blood enters separation bag, the blood component of greater density-mainly be erythrocyte, under action of centrifugal force,, withdraw from separation bag by the packed red cells pipeline then to the outside of separation bag hematocrit; And the less composition of those density, as: blood plasma, platelet and/or leukocyte can be transported in the collecting bag by rich composition blood plasma pipeline by blood plasma pump; When rich composition blood plasma enters the bottom of collecting bag, composition that density is bigger such as platelet and/or leukocyte are under action of centrifugal force, to the outside of collecting bag hematocrit, the composition of collecting is stayed in the collecting bag, and the less poor blood plasma of density withdraws from the collecting bag by poor blood plasma pipeline, return to the blood donor after poor blood plasma and packed red cells mix, or be collected in the transfering bag.

Separation bag/collecting bag: the self structure by bag is fixed on the control folder on the blood component seperator rotating cylinder, cooperation by multi-lumen tube, utilize the high efficiency fluid principle of dynamics, under the driving force of blood component seperator rotating cylinder, in separation bag, the anticoagulant separation of whole blood is become packed red cells, leukocyte and platelet rich plasma, realize the efficiently concentrating of products of separated again by collecting bag, thereby realize the isolating optimum efficiency of blood component.

Multi-lumen tube: it is assemblied on the blood component seperator rotating cylinder with fixed top connection of turret head and lower contact, so that cooperate with separation bag, reverse the reconciliation twisting action by the rotating cylinder of blood component seperator and two kinds of different rotation rates initiations of rotating cylinder bracket, thereby cooperate the blood component seperator to realize that the connected sum of separation bag and pipeline drives the high speed rotating of separation bag, to finish the optimization of separation process, improved collection efficiency.

This utility model has been owing to adopted supervising device, separation bag and the multi-lumen tube with said structure novelty, complete function, make single blood sampling cell separator of this disposable use band biofilter have to the blood component of being gathered can carry out efficiently separating automatically, the higher remarkable advantage of collection efficiency.Simultaneously,, therefore, can reduce cross infection to greatest extent, protection blood donor's health owing to adopt sealed self-circulation system.
