Abstract
The invention discloses a kind of quick peripheral plasma collector and its application methods, including air bag, the first capillary, hemofilter, the second capillary；The upper end of first capillary is socketed in air bag；The lower end of first capillary connects hemofilter upper end；The lower end of the hemofilter connects the second capillary；The air bag, the first capillary, hemofilter, the second capillary are connected to setting from top to bottom；The bosom of the hemofilter is equipped with blood filter membrane.Red blood cell in peripheral blood is efficiently separated out by the present invention by the blood filter membrane in hemofilter, significantly increases the convenience of micro sampled plasma.
Description
Technical field
The present invention relates to a kind of quick peripheral plasma collector and its application methods.
Background technique
Currently, many quickly detections need to be detected using blood plasma, blood generally is centrifugated using venous blood both at home and abroad
Slurry, and the method needs to acquire more blood, and needs special installation, it is now external to acquire peripheral blood capillary heparin tube
Red blood cell and blood plasma separate precedent not yet, realization of the invention will make it possible micro sampled plasma.
Summary of the invention
In view of the deficiencies of the prior art mentioned above, problems solved by the invention are as follows: providing a kind of take a blood sample by tip can
The collector and its method of quantitatively micro blood plasma are obtained after red blood cell and blood plasma are separated.
To solve the above problems, the technical solution adopted by the present invention is as follows:
A kind of quick peripheral plasma collector, including air bag, the first capillary, hemofilter, the second capillary；Described first mao
The upper end of tubule is socketed in air bag；The lower end of first capillary connects hemofilter upper end；Under the hemofilter
The second capillary of end connection；The air bag, the first capillary, hemofilter, the second capillary are connected to setting from top to bottom；It is described
Hemofilter bosom be equipped with blood filter membrane.
Further, internal diameter of the internal diameter of second capillary less than the first capillary.
A kind of application method of quick peripheral plasma collector, steps are as follows:
S1, the first capillary, hemofilter, the second capillary are successively sealed to connecting；
S2, peripheral blood is taken using the capillary action of the first capillary, acquire and air bag is socketed in first mao after finishing
The upper end of tubule；
S3, air bag is squeezed, so that peripheral blood is flowed from the first capillary to hemofilter, it is red thin after peripheral blood passes through hemofilter
Born of the same parents are isolated by filtration the blood plasma on the blood filtration membrane, separated and penetrate into the second capillary from blood filter membrane, realize peripheral blood
The separation of middle blood plasma and red blood cell.
Further, the internal diameter of second capillary is less than the internal diameter of the first capillary in order to which blood plasma is from the first capillary
Pipe sucks in the second capillary.
Further, second capillary selects different inner diameters and length to realize batcher function according to the demand of capacity
Energy.
Beneficial effects of the present invention
Red blood cell in peripheral blood is efficiently separated out by the present invention by the blood filter membrane in hemofilter, can be taken a blood sample by tip
Obtain quantitative micro blood plasma.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is fractionation structural representation of the invention.
Specific embodiment
The content of present invention is described in further detail with reference to the accompanying drawing.
As illustrated in fig. 1 and 2, a kind of quick peripheral plasma collector, including air bag 1, the first capillary 2, hemofilter 3,
Two capillaries 5.The upper end of first capillary 2 is socketed in air bag 1；The lower end of first capillary 2 connects filter
3 upper end of blood device；The lower end of the hemofilter 3 connects the second capillary 5；The air bag 1, the first capillary 2, hemofilter 3,
Second capillary 5 is connected to setting from top to bottom；The bosom of the hemofilter 3 is equipped with blood filter membrane 4.Second capillary
Internal diameter of the internal diameter of pipe 5 less than the first capillary 2
A kind of application method of quick peripheral plasma collector, steps are as follows:
S1, the first capillary 2, hemofilter 3, the second capillary 5 are successively sealed to connecting.
S2, air bag 1 is socketed in after taking peripheral blood, acquisition to finish using the capillary action of the first capillary 2
The upper end of first capillary 2.
S3, air bag 1 is squeezed, so that peripheral blood is flowed from the first capillary 2 to hemofilter 3, when peripheral blood passes through hemofiltration
Red blood cell is isolated by filtration in blood filter membrane 4 after device 3, and the blood plasma separated penetrates into the second capillary 5 from blood filter membrane,
Realize the separation of blood plasma and red blood cell in peripheral blood.
It is further preferential, the internal diameter of second capillary 5 less than the first capillary 2 internal diameter in order to which blood plasma is from the
One capillary 2 sucks in the second capillary 5.Further preferably, second capillary 5 selects different according to the demand of capacity
Internal diameter and length are to realize batcher function.
Red blood cell in peripheral blood is efficiently separated out by the present invention by the blood filter membrane 4 in hemofilter 3, can pass through end
Tip blood sampling obtains quantitative micro blood plasma.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
