Abstract
The utility model discloses a centrifugal leukocyte removing device which comprises a leukocyte filter and a rotary separating mechanism. The centrifugal leukocyte removing device is characterized in that plasma layers, platelet and leukocyte layers and erythrocyte layers can be separated from whole blood by the rotary separating mechanism, platelets and erythrocytes are led out from the rotary separating mechanism via an output guide tube, the output guide tube is connected with the leukocyte filter, the leukocyte filter is of a conical tower-shaped structure, the top of the leukocyte filter is connected with the output guide tube, and the bottom of the leukocyte filter is connected with a platelet collecting bag and is fixed onto a fixing seat. The centrifugal leukocyte removing device has the advantages that the platelets can be separated from the leukocytes by the centrifugal leukocyte removing device and can be collected into the platelet collecting bags via a guide tube, and the leukocytes can be retained in the leukocyte filter.
Description
Technical field
The utility model relates to medical instruments field, is specifically related to a kind of centrifugal leucocyte-removing device.
Background technology
When using blood cell density gradient centrifugation to carry out separation to blood constituent, during because of leucocyte and the centrifugal layering of blood platelet at same layer, not easily separated, usual way is: from blood, isolate after leucocyte and blood platelet, through filtering, leucocyte is separated again, both caused leukocytic waste, efficiency is low again.Blood ingredient separator as the applicant design, comprises separated bag, and described separated bag is strip, have flexible, for stored blood; One end of separated bag is provided with blood input port, and one end is provided with composition and derives path, for derive at least a portion composition of blood from separated bag.Use this device to carry out after separation blood, in separated bag, isolate plasma separation layer, blood platelet and leucocyte separating layer, red blood cell separating layer.Blood platelet and leucocyte separating layer are carried out separation after efferent duct output is collected again, very trouble.
Summary of the invention
In order to address the above problem, the utility model provides a kind of can isolate leukocytic device effectively from leucocyte and blood platelet mixed liquor.
The utility model technical solution problem technical scheme is: a kind of centrifugal leucocyte-removing device, comprise Lv Baiqihe rotating separation mechanism, whole blood goes out plasma layer, blood platelet and leukocytic cream, red blood cell layer by rotating separation organizational separation, blood platelet and leucocyte are derived from rotating separation mechanism through output duct, described output duct is connected with the white device of filter, the white device of described filter is coniform pyramidal structure, its top is connected with output duct, and bottom is connected with Thrombocyte collecting bag and is fixed on holder.
The inwall of the white device of described filter is that turriform is step-like.
The beneficial effects of the utility model are, the blood platelet obtaining in separation bag and leucocyte are imported to filter Bai Qizhong, due to leucocyte and hematoblastic proportion different, blood platelet is collected in Thrombocyte collecting bag by conduit, white blood cell retention is at filter Bai Qizhong.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model;
The white device profile of Fig. 2 filter of the present utility model;
1 Thrombocyte collecting bag, 2 rotating separation mechanisms, 3 output ducts, 4 red blood cell layers, the white device of 5 filter, 6 blood platelets and leukocytic cream, 7 plasma layers, 8 holders, 9 conduits.
The specific embodiment
A kind of centrifugal leucocyte-removing device, comprise the white device 5 of filter and rotating separation mechanism 2, whole blood in rotating separation mechanism 2 carries out Isopyknic separation by rotating centrifugal effect, isolate plasma layer 7, blood platelet and leukocytic cream 6, red blood cell layer 4, blood platelet and leucocyte are derived from separated bag 10 through output duct 3, described output duct 3 is connected with the white device 5 of filter, the white device 5 of described filter is cone-shaped structure, its top is connected with output duct 3, bottom is fixed on holder 8, bottom is provided with conduit 9, and conduit 9 is connected with Thrombocyte collecting bag 1.The preferred turriform of inwall of the white device of described filter is step-like, as shown in Figure 2, when blood platelet and leukocytic mixed liquor enter filter Bai Qizhong, according to the larger leucocyte docile of centrifugal principle proportion, under turriform step, blood platelet directly enters in Thrombocyte collecting bag by conduit.
Use the utility model the blood platelet after the separation of blood constituent separator and leukocytic cream can be carried out to further separation, blood platelet is collected in Thrombocyte collecting bag by conduit, white blood cell retention is at filter Bai Qizhong, the leucocyte that is trapped in the white device of filter can be passed in blood donor's body again, avoid leukocytic waste, avoided the impact of leucocyte on acceptor simultaneously.
Claims (2)
1. a centrifugal leucocyte-removing device, comprise Lv Baiqihe rotating separation mechanism, it is characterized in that: whole blood goes out plasma layer, blood platelet and leukocytic cream, red blood cell layer by rotating separation organizational separation, blood platelet and leucocyte are derived from rotating separation mechanism through output duct, described output duct is connected with the white device of filter, the white device of described filter is coniform pyramidal structure, and its top is connected with output duct, and bottom is connected with Thrombocyte collecting bag and is fixed on holder.
2. centrifugal leucocyte-removing device according to claim 1, is characterized in that: the inwall of the white device of described filter is that turriform is step-like.
