Abstract
The utility model discloses a mechanical blood plasma sampling and blood infusion device, which comprises an anticoagulant pin, pipelines, a tee joint, a blood filter, an air filter and an interface of a centrifugal cup. The anticoagulant pin is communicated with the tee joint through the pipelines, and the tee joint is communicated with the blood filter through the pipelines. The other end of the blood filter is communicated with the interface of the centrifugal cup through the pipelines, and the blood filter is communicated with the air filter through the pipelines. The utility model provides a disposable mechanical blood plasma sampling and blood infusion device for an automatic single sampler for blood, and the utility model can avoid cross infection and is favorable to the increasing of the health of blood donors and the quality of raw blood plasma.
Description
This utility model relates to medical blood transfusion, blood sampling, blood separation, blood recovery apparatus, more specifically relates to a kind of Mechanical blood taking and infusion device.
In order to produce blood products, usually healthy people (blood donor) blood is gathered, blood donor's blood is gathered by the road to plastic blood bag, after blood is gathered, take off the blood bag, the blood bag that blood will be housed is again delivered to blood separating chamber and is placed high speed centrifuge to carry out blood separation, takes out plastic blood bag and working pressure plasma-separating clip again, required composition (as blood plasma) is pressed into the plastics transfering bag, sends the blood bag of the erythrocyte of remainder or other composition back to Blood Sampling Room again and feed back to the blood donor.For a long time, be all and so come and go manual operations, easily cause cross infection, be unfavorable for the raising of blood donor's health and raw blood plasma quality.
For this reason, the purpose of this utility model provides a kind of disposable Mechanical blood taking and infusion device of singly adopting machine automatically that is specifically designed to.
To achieve these goals, this utility model adopts following technical scheme: this blood exchange transfusion set comprises anticoagulant contact pin, pipeline, threeway, blood filter, air filter, Centrifuge Cup interface, it is characterized in that: described anticoagulant contact pin is connected with threeway by pipeline, described threeway is connected by pipeline with blood filter one end, the described blood filter other end is connected with the Centrifuge Cup interface by pipeline, and described blood filter is connected with air filter by pipeline.
Because this utility model is connected after anticoagulant contact pin, blood filter, air filter, Centrifuge Cup interface are connected by pipeline each other, make it singly to adopt machine automatically disposable Mechanical blood taking and infusion device is provided for blood, so just can avoid cross infection, and help the raising of blood donor's health and raw blood plasma quality.
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is this utility model structural representation.
Fig. 2 is one of this utility model example structure sketch map.
Fig. 3 is two of this utility model example structure sketch map.
Fig. 4 is three of this utility model example structure sketch map.
See also shown in Figure 1ly, this blood exchange transfusion set comprises anticoagulant contact pin 1, pipeline 2, threeway 3, blood filter 4, air filter 5, Centrifuge Cup interface 6.Described anticoagulant contact pin 1 is connected with threeway 3 by pipeline 21, and spacer sleeve is provided with two positioning sleeves 7 between the pipeline 21 of anticoagulant contact pin 1 and threeway 3.Described threeway 3 is connected by pipeline 22 with blood filter 4 one ends (lower end).Described blood filter 4 other ends (upper end) are connected with Centrifuge Cup interface 6 by pipeline 23, and also spacer sleeve is provided with two positioning sleeves 8 on the pipeline 23 of this section.The positioning sleeve 7 and 8 the purpose that is provided with are so that after this utility model places blood singly to adopt on the machine automatically, be provided with blood pump at the side between two positioning sleeves 7, between two positioning sleeves 8, to quicken the liquid flow in the pipeline.Described blood filter 4 upper ends are connected with air filter 5 by pipeline 24, also are arranged with intermediate plate 9 between blood filter 4 and air filter 5, and intermediate plate 9 can be used as the switch of air filter 5.
Please continue to consult shown in Figure 1, in the present embodiment, blood filter 4 is a cavity body, be provided with blood filtration net 41 in it, the shape of blood filtration net 41 and size are roughly the same with cavity body, in Fig. 1 blood filtration net 41 be shaped as a cylinder, its size dimension is wanted to place in the cavity body, certainly, blood filter 4 also can be other shape.The two ends of blood filter 4 are directly taken over road 22, pipeline 23 and 24 respectively.
