Abstract

The utility model relates to a blood cell separator with centrifugal separation principle, comprising a blood needle joint, a blood return needle joint, an anticoagulant bag and a salt water bag, which are connected to a centrifugation separator via a multi-cavity pipe; the centrifugation separator is composed of a centrifugation bin, a separation bag positioned in the centrifugation bin, and a collecting bag. A rich constituent blood plasma transporting pipe controlled and connected via a blood plasma pump is provided between the separation bag and the collecting bag. Adopting the structure chiefly solves the technical problem that the existing blood cell centrifugal separator adopts the single centrifugal separation structure to separate the blood cells, which leads to that the blood cells in the blood can not be fully utilized; disposable using and completing the complete-set the single blood sampling cell separation and recirculation processes of the blood sampling process, the centrifugation process, the separation process and the recirculation process can reduce the cross infections in high limit, protects the health of the blood donor and saves the blood resource.

Description

Disposable use blood cell separator
Technical field:
This utility model relates to the medical consumption utensil of a kind of disposable use, particularly a kind of disposable use blood cell separator of centrifugalize principle.
Background technology:
The blood of human body composition than permutatation, is respectively erythrocyte, granulocyte, lymphocyte, platelet and blood plasma according to it.Only can import its desirable ingredients to patient as required in the medical treatment, like this, be a kind of saving to blood medicine source.
At present, domesticly be equipped with the blood separator except some metropolitan Blood Centers, it all is manual collection that most of regional hemocyte separates.After the blood of healthy blood donor is gathered, through external centrifugal, also be defeated by the blood donor again, this process is not a sealing and circulating, also defeated error and cross infection very easily occur.Therefore; China's utility model patent description (Granted publication number: CN2404534Y) disclose the medical consumption equipment of the matching used disposable use of a kind of intermittent current dynamic formula blood cell separator; mainly by the anticoagulant bag; sampler bag; plasma bags; the product collecting bag; separate cup; blood taking needle; liquid medicine filter; perforator and connection tube; formations such as various terminal; have closed circulating system of one's own; can disposablely be used to complete blood sampling; centrifugal; separate; feeding back a complete set of single blood sampling cell separates; the feedback process; can reduce cross infection to greatest extent; protection blood donor health is saved blood resource.
But still there is certain defective in this blood cell separator, mainly is that separate cup adopts the single centrifugalize to gather hemocyte, makes that the hemocyte in the blood can not be fully utilized.
The utility model content:
The purpose of this utility model provides a kind of disposable use blood cell separator, and solve existing hemocyte centrifugal separator and adopt single centrifugalize structure washed corpuscles, so that the technical problem that can not be fully utilized of the hemocyte in the blood.
For solving the problems of the technologies described above, this utility model is achieved in that
A kind of disposable use blood cell separator, comprise into the blood needle adapter, return blood needle adapter, anticoagulant bag and bag of saline, they are connected to a centrifuge mechanism by the multi-cavity pipeline, it is characterized in that: this centrifuge mechanism is made up of a centrifugal storehouse and the separation bag, the collecting bag that are positioned at centrifugal storehouse, and a rich composition blood plasma carrier pipe by blood plasma pump control connection is arranged between separation bag and the collecting bag.
Connect the blood needle adapter and return on the pipeline of blood needle adapter and have pressure transducer.
Hygrosensor, hygrosensor and rotor balancing detector are arranged in this centrifugal storehouse.
The mat said structure the utlity model has following advantage:
1, has separation bag and collecting bag in the centrifugal storehouse of the present utility model, after separation bag carries out the centrifugalize first time to blood, by blood plasma pump rich composition blood plasma is transported to collecting bag and carries out the secondary centrifuging separation again, guaranteed the hemocyte in the blood is utilized fully.
2, this utility model can be disposable be used to complete blood sampling, centrifugal, separate, feed back that a complete set of single blood sampling cell separates, the feedback process, can reduce cross infection to greatest extent, protection blood donor health, saving blood resource.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
See also Fig. 1, it is the structural representation of the disposable use blood cell separator of this utility model.As shown in the figure: it comprises into blood needle adapter 1, returns blood needle adapter 2, anticoagulant bag 3 and bag of saline 4, and they are connected to a centrifuge mechanism 6 by multi-cavity pipeline 5.
This centrifuge mechanism 6 is made up of with the separation bag 62, the collecting bag 63 that are positioned at centrifugal storehouse 61 a centrifugal storehouse 61, and a rich composition blood plasma carrier pipe 51 by blood plasma pump control connection is arranged between separation bag 62 and the collecting bag 63.
Connect blood needle adapter 1 and return on the pipeline of blood needle adapter 2 and have pressure transducer 11,21.
In this centrifugal storehouse 61 hygrosensor, hygrosensor and rotor balancing detector are arranged.
In running, the anticoagulant whole blood is pumped in the rotating separation bag 62 under the effect of whole blood pump, and the isolating first step of blood constituent occurs in separation bag 62, and the first time that can be regarded as the blood component collection process is centrifugal.After whole blood A entered separation bag, the blood constituent of greater density (mainly being erythrocyte) under action of centrifugal force, to the outside of separation bag 62 hematocrit, withdrawed from separation bag by PRBC (packed red cells) pipeline 52 then; And the less composition of those density, as: blood plasma, platelet and/or hundred cells can be moved in the collecting bag 63 by CRP (rich composition blood plasma) pipeline 51 by blood plasma pump, and the isolating second stage of blood constituent is here carried out.The second time that can be regarded as the blood component collection process is centrifugal, and when CRP enters the bottom of collecting bag 63, the composition that density is bigger is gone into platelet and/or hemocyte under action of centrifugal force, overstocks to the outside of collecting bag 63.The composition of collecting is stayed in the collecting bag 63, and the less CPP (poor blood plasma) of density withdraws from collecting bag by CPP pipeline 53.CPP and PRBC return to blood donor/patient after mixing, (or collecting CPP to transferring in the bag 7).

Claims (3)
