Abstract
The utility model relates to a centrifugal separator of plasma single sampling. The utility model comprises a plasma centrifugal separating unit and catheters. The utility model is characterized in that the plasma centrifugal separating unit is composed of a stator, a rotor, and a fixture; a plasma outlet of the stator and an inlet for whole blood are respectively connected with a blood donor and a plasma bag through the catheters; each catheter is composed of a plastic puncture needle, a blood sampling needle, an air filter, a filter for the whole blood, and a medical plastic pipe. A liquid collecting chamber is arranged at the bottom of the separating unit, and the blood waste can be reduced.
Description
The utility model relates to on-the-spot blood sampling and blood plasma, haemocyte isolation technics, is specifically related to be used to take a blood sample and the blood plasma list of blood plasma, haemocyte separating treatment is adopted centrifugal separator.
In recent years, domesticly a large amount of fully automatic blood composition seperators have been introduced, only PCS/PLUST and two kinds of types of PCSz of the production of U.S. HAEMONETICS company just have more than 2000, it is disposable product that supporting with it blood plasma list is adopted centrifugal separator, annual consumption is very big, dependence on import needs a large amount of foreign exchanges fully, and a kind of energy of domestic urgent need substitutes the disposable use blood plasma list of import, relative low price, dependable performance and adopts centrifugal separator.
ZL99227303.X has introduced a kind of blood component separate cup, but it has some deficiency: because its bottom is flat, cup internal memory blood is more when blood sampling finishes, and causes blood to waste after abandoning.
The purpose of this utility model is to make design improvement at the above-mentioned deficiency of prior art, and the PCS/PLUST that provide a kind of blood less wastage, produces with HAEMONETICS company and two kinds of type blood plasma of PCSZ list are adopted the matching used disposable blood plasma list of seperator and adopted centrifugal separator.
For achieving the above object, the solution that the utility model is taked is: comprise blood plasma centrifugal separating device and conduit, it is characterized in that the blood plasma centrifugal separating device is by stator, rotor, clamping device three parts constitute, stator is by the whole blood flow channel, the blood plasma flow pass constitutes, rotor is by inner core, urceolus, dynamic seal ring, retainer plate constitutes, can rotate relatively between dynamic seal ring and the pad, and keep sealing, the blood plasma outlet of stator is connected with plasma bags by conduit, and conduit is by the plastics puncture needle, blood taking needle, air strainer, whole blood filtrator and medical plastic pipe are formed.
Whole blood flow channel of the present utility model is made of the whole blood inlet and the whole blood conduit that connect successively.Blood plasma outlet lower end is flowed out the gap through blood plasma and is communicated with the inner core of centrifugal separating device.Clamping device is made up of guard shield, pad, stator and elastic caoutchouc bowl.Urceolus has the arc waisting, circular arc slope and liquid collecting room, and the whole blood conduit reaches the liquid collecting room of urceolus always.
The utility model is beneficial to blood plasma and separates with haemocyte owing to design arc waisting, circular arc slope on urceolus; Tube bottom has designed liquid collecting room outside, so that when blood sampling finished, tube internal memory oligemia had reduced the waste of blood.Rotor when high speed rotating and stator form relative motion, for guaranteeing the centrifugal separating device excellent sealing performance, its dynamic seal ring that produces relative motion is made with the aluminium oxide ceramics of hard wear resistant, and pad is made with phenolics, frictional resistance is little between the two, favorable sealing property.The pressure that puts on the clamping device is born by the elastic caoutchouc circle, in order to avoid descend because of ambient pressure causes the cylindrical shell sealing property in use, installation process.The elastic caoutchouc circle is made by medical grade silicon rubber.Conduit is made of plastics puncture needle, blood taking needle, air strainer, whole blood filtrator, whole blood pipeline, anti-coagulants pipeline, outlet blood plasma pipeline, and material therefor is medical polyvinyl plastics.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a guide-tube structure synoptic diagram embodiment illustrated in fig. 1.
Among Fig. 1, it is supporting that the blood plasma list is adopted centrifugal separator and hydro-extractor and peristaltic pump, blood plasma enters from whole blood inlet 5, flow into the liquid collecting room 14 of urceolus 1, rotor high-speed rotation along whole blood conduit 7, haemocyte is different because of proportion with blood plasma, the centrifugal force difference that produces, the haemocyte that proportion is bigger rises with urceolus 1 rotation, through circular arc slope 13, to arc waisting 12 places, blood plasma and haemocyte secondary separation.Along with whole blood constantly enters, a tube content volume constantly increases, and the blood plasma that is positioned at the rotor centre position then flows out gap 15, blood plasma outlet 6 by blood plasma and enters plasma bags along the blood plasma flow pass.When haemocyte is put aside between urceolus 1 and inner core 2 when a certain amount of, whole blood temporarily stops to enter centrifugal separating device, in urceolus, inject physiological saline dilution haemocyte, enter reverse direction along whole blood and feed back the blood donor, feedback finishes, and carries out separating cycle next time again, until collecting predetermined plasma volume, at last the haemocyte in the urceolus is added physiological saline dilution back and all feed back the blood donor, finish the slurry feedback process of adopting.Centrifugal separating device and conduit are taken off by adopting on the pulp grinder, concentrate to place the contaminative refuse bag to destroy in the lump.Pad 10 is static with top, and dynamic seal ring 4 rotates relative to pad 10, and keeps sealing, and dynamic seal ring 4 usefulness aluminium oxide ceramics are made, and pad 10 usefulness phenolics are made.The stator 11 of clamping device in use is clipped on the shelf of blood plasma machine, and the pressure that puts on the centrifugal separating device is born by elastic caoutchouc bowl 9, in order to avoid centrifugal device is subjected to outside destroy, guard shield 8 compresses rubber bowl.3 sealings of epitrochanterian aluminium foil retainer plate pressuring action.
Among Fig. 2, threeway 20 1 ends connect the anti-coagulants pipeline by plastics puncture needle 16, and the other end is connected with the blood donor by whole blood filtrator 19, air strainer 18, blood taking needle 17.
Disposable blood plasma list of the present utility model is adopted centrifugal separator and is used through clinical trial, proves the disposable centrifugal separator indistinction of singly adopting of its security, reliability and import, aseptic, nontoxic, the no thermal source of collecting blood.
