Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1 and Fig. 4, the centrifugal fixture of blood catheter of the present invention is made up of centrifugal fixator 1 and Centrifuge Cup 2, and Centrifuge Cup 2 is enclosed within the outside of centrifugal fixator 1.Formed between Centrifuge Cup 2 and centrifugal fixator 1 support, the relation such as secondary clamps, hang, protect, unexpected broken pipe dirt reception, Centrifuge Cup 2 not only ensure that the centrifugal mass of blood catheter, and serves good protective action to biohazard.Centrifugal fixator 1 preferably adopts polyamide, ABS, POM or aluminium to make, and Centrifuge Cup 2 also preferably adopts polyamide, ABS, POM or aluminium to make.
Introduce the structure of centrifugal fixator 1 below in detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, centrifugal fixator 1 comprises: upper cover 11 and lower cover 12, and the two forms the agent structure of centrifugal fixator 1.Upper cover 11 and lower cover 12 realize being rotationally connected by connecting axle 13, and the two realizes fastening by fastening buckle 14.Upper cover 11 and lower cover 12 surround the placed cavity 15 for straight line fix blood fluid catheter jointly, and the two ends of placed cavity 15 are uncovered, and placed cavity 15 entirety is in straight-tube shape.Due to placed cavity 15 straight line fix blood fluid catheter, so can ensure that blood catheter does not bend when centrifugal, thus can solve blood catheter centrifugal time haemocyte wall built-up problem.The outer wall of upper cover 11 and lower cover 12 be formed with attacker 16 and hang boss 17, hanging boss 17 makes centrifugal fixator 1 can be suspended in Centrifuge Cup 2, so, centrifugal fixator 1 just can not be inserted in tightly in Centrifuge Cup 2 because of the effect of centrifugal force and can not get out, and attacker 16 makes operating personnel to be taken out in Centrifuge Cup 2 by centrifugal fixator 1 easily.
In order to prevent blood catheter in centrifugal process mobile in the placed cavity 15 of centrifugal fixator 1, as the preferred scheme of one, the chamber wall of placed cavity 15 is formed with anti-skidding spiral lamination (not shown), anti-skidding spiral lamination effectively can increase the frictional force between blood catheter and placed cavity 15 inwall.
More preferably, upper cover 11 and lower cover 12 have smooth outer wall, and the one end of inserting Centrifuge Cup 2 is formed with insertion guide part 18.Because upper cover 11 and lower cover 12 have smooth outer wall, so contact area between itself and the inwall of Centrifuge Cup 2 is large, therefore centrifugal fixator 1 uniform force when Centrifuge Cup 2 clamps centrifugal fixator 1, the stressed of the blood catheter in placed cavity 15 is also tending towards even.Inserting guide part 18 can make centrifugal fixator 1 be inserted into very easily in Centrifuge Cup 2.
The using method of the centrifugal fixture of this blood catheter is as follows:
(1), by blood catheter code together, put into the placed cavity 15 of centrifugal fixator 1, blood catheter must be full by placed cavity 15 yards;
(2), by fastening buckle 14 by upper cover 11 and lower cover 12 fastening, then centrifugal fixator 1 is suspended in Centrifuge Cup 2;
(3), by Centrifuge Cup 2 put into centrifuge angle rotor, the program arranged by centrifuge is centrifugal;
(4), after centrifugal end, take out centrifugal fixator 1, and blood catheter is taken out in centrifugal fixator 1, enter the next flow process of blood sample process.
Have the centrifugal fixator 1 of said structure, it often criticizes centrifugal used time about 30min for realizing batch process blood catheter, as seen its processing blood conduit sample amount of having greatly, advantage fast, can effectively increase work efficiency.
Introduce the another kind of structure of centrifugal fixator 1 below in detail.
With reference to Fig. 4, Fig. 5 and Fig. 6, centrifugal fixator 1 comprises: upper cover 11 and lower cover 12, and the two forms the agent structure of centrifugal fixator 1.Upper cover 11 and lower cover 12 realize being rotationally connected by connecting axle 13, and the two realizes fastening by fastening buckle 14.Upper cover 11 and lower cover 12 surround the placed cavity 15 for straight line fix blood fluid catheter jointly, the two ends of placed cavity 15 are uncovered, and the inside of placed cavity 15 is also formed with some straight lines loads guide groove 19, each straight line loads in guide groove 19 can place a blood catheter, can realize single processing blood conduit sample like this.The middle part that straight line loads guide groove 19 is preferably formed with bar coded sticker rest area 20.The outer wall of upper cover 11 and lower cover 12 be formed with attacker 16 and hang boss 17.
As the preferred scheme of one, the outer wall of upper cover 11 and lower cover 12 is formed with anti-deformation wedge post 21.Anti-deformation wedge post 21 can effectively prevent centrifugal fixator 1 from deforming due to stress after fixed sample, thus the blood catheter in centrifugal fixator 1 can be prevented to be out of shape, and then ensures centrifugal effect.
More preferably, one end that upper cover 11 and lower cover 12 insert Centrifuge Cup 2 is formed with insertion guide part 22, inserts guide part 22 and centrifugal fixator 1 can be made to be inserted into very easily in Centrifuge Cup 2.
The using method of the centrifugal fixture of this blood catheter is as follows:
(1), single blood catheter is put into centrifugal fixator 1 straight line load guide groove 19, the bar coded sticker of blood catheter is placed on bar coded sticker rest area 20;
(2), by fastening buckle 14 by upper cover 11 and lower cover 12 fastening, then centrifugal fixator 1 is suspended in Centrifuge Cup 2;
(3), by Centrifuge Cup 2 put into centrifuge angle rotor, the program arranged by centrifuge is centrifugal;
(4), after centrifugal end, take out centrifugal fixator 1, and blood catheter is taken out in centrifugal fixator 1, enter the next flow process of blood sample process.
The centrifugal fixator with said structure for realizing single processing blood conduit, when its with the centrifugal fixator for realizing batch process blood catheter with the use of time, the centrifugal technical barrier of current blood catheter can be solved completely.
Empirical tests, uses haemocyte and the blood plasma of blood catheter of the present invention centrifugal fixture separating blood conduit, can obtain following beneficial effect:
(1), the haemocyte of blood catheter and being separated of blood plasma (serum) can be completed fast in 30min, thus ensure that the quality detecting sample, and then ensure that the accuracy of testing result;
(2), placed cavity straight line fix blood fluid catheter, ensure that blood catheter does not bend when centrifugal, thus solve blood catheter centrifugal time haemocyte wall built-up problem;
(3), the haemocyte in blood catheter can be separated completely with blood plasma (serum), solve the Secondary cases haemolysis problem that sample exists when subzero less than 20 DEG C Cord blood;
(4), for batch process blood catheter centrifugal fixator can in a large number, fast processing needs centrifugal blood catheter sample, substantially increases operating efficiency; Monomer blood catheter sample after batch process can be solved for the centrifugal fixator of single processing blood conduit; The two with the use of, the centrifugal technical barrier of current blood catheter can be solved completely;
(5), formed between Centrifuge Cup and centrifugal fixator support, the relation such as secondary clamps, hang, protect, unexpected broken pipe dirt reception, Centrifuge Cup not only ensure that the centrifugal mass of blood catheter, and serves good protective action to biohazard.
It should be noted that, above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
