Abstract
The utility model relates to a high-capacity plasma separation cup, which comprises a fixed head, a sealing cup, a sealing gasket, a sealing ring, an upper cover, a lower cover, a cup cover, a composite cup core, a cup body and a central pipe. The composite cup core consists of a fixed ring, a cup core and a guide disc. On the basis that the outer diameter of the cup body of the separation cup is unchanged, the outer diameter of the cup core is expanded to be 22-35mm to form the high-capacity plasma separation cup with capacity of 320-370ml.
Description
Technical field
The utility model relates to a kind of medicine equipment, particularly a kind of large capacity plasma separation cup that significantly increases displacement volume in the situation of separate cup cup size constancy.
Background technology
The plasma separation cup is to utilize centrifugal principle to carry out one of important means of plasma separation in the modern biomedical engineering field, its basic principle is to utilize blood plasma collecting machine to drive plasma separation cup High Rotation Speed, make the haemocyte in the plasma separation cup carry out undamaged the separation with plasma fraction, to extract plasma fraction.
The specification capacity of at present plasma separation cup use is about 280 milliliters, the displacement volume of plasma separation cup mainly is to be determined by the plasma separation cavity volume that forms between cup in the plasma separation cup and the cup nuclear, this capacity makes the plasma separation cup when carrying out sampled plasma, and the sampled plasma amount that once gathers circulation can only reach about 400 milliliters.Because human body and mammal such as horse, the blood characteristics of ox etc. is close, but doubly a lot of greater than human body aspect build, therefore, in related scientific research, need of production gathers large mammal such as horse, during the blood plasma of ox etc., once gather often very large requirement of total amount, at present artificial collection commonly used, separate, the mode that feeds back is carried out, this mode exists loaded down with trivial details, working strength is large, the defective that pollution risk is large, but when the plasma separation cup that uses the work on hand capacity carries out the machine collection, because it is less that one way gathers plasma volume, when the collection total amount is very large, there is again the global cycle of needs often, the defective that time is long.
Summary of the invention
Above defective in view of present normal plasma separate cup, the purpose of this utility model is a kind of external structure, size that does not change existing plasma separation cup of design, significantly increase the separate cup displacement volume, the specification capacity of separate cup is increased to about 360 milliliters, and once the plasma collection amount of collection circulation can reach the large capacity plasma separation cup about 500 milliliters.
The large capacity plasma separation cup that the utility model proposes is realized above-mentioned purpose by following architectural feature:
Large capacity plasma separation cup of the present utility model comprises static head, obturating cup, sealing gasket, sealing ring, upper cover, lower cover, bowl cover, cup nuclear, cup, central tube, cup nuclear is connected with cup, it is characterized in that cup nuclear is compound cup nuclear, this compound cup nuclear is made of retainer ring, cup nuclear core, positioning disk, retainer ring welds by pad one with cup nuclear core, blood plasma, haemocyte overflow seam are arranged between the two, cup nuclear core and positioning disk jointly form plasma separation chamber with cup by pad two welding between the two.
In order significantly to increase the displacement volume of above-mentioned Centrifuge Cup, the utility model is examined cup core on the constant basis of above-mentioned Centrifuge Cup cup outside dimension outside dimension expands to 22-35mm, is the large capacity plasma separation cup of 320-370ml thereby form volume.
Operation principle of the present utility model is as follows:
This novel high-capacity plasma separation cup and blood plasma collecting machine are used, separate cup is under the drive of blood plasma collecting machine, cup, bowl cover, compound cup nuclear part High Rotation Speed, by static fixing entrance, lower cover, central tube flows into the interior anticoagulated whole blood of rotation cup under centrifugal action, separate in the plasma separation chamber that between cup and compound cup nuclear, forms, anticoagulated whole blood is isolated the haemocyte layer of distal end and the plasma layer of proximal part, after the haemocyte that is separated in the plasma separation chamber fills up, plasma layer is pushed into the plasma collection chamber of separate cup by the overflow channel on the compound cup nuclear, the blood plasma overflow channel that forms by upper cover and lower cover flows to static head outlet, blood plasma enters plasma collection container, the blood platelet that density is less in blood cell composition and leucocyte composition enter the plasma collection chamber, this moment separate cup in without plasma fraction, and be full of by blood cell composition, and when overflowing by the blood plasma overflow channel, the blood plasma collecting machine sniffer detects cell component automatically, and blood plasma collecting machine stops to gather the feedback program that enters haemocyte automatically.
The utility model possesses following superiority:
1, security: machine moves whole setting programs automatically, and is safe and reliable;
2, versatility: cup appearance and size and install and use size without change, realize being used with the conventional blood plasma collecting machine that uses, do not need to design and produce separately corollary equipment.
3, quickness and high efficiency: avoided manual collection and common capacity separate cup loaded down with trivial details, the time is long, efficient is low.
