Abstract
The utility model relates to a hollow gel-filling vacuum blood taking tube, which comprises a test tube, blood separating gel, accelerating agent and a sealing rubber plug, wherein the bottom and the inner wall inside the test tube are coated with the accelerating agent, and the blood separating gel is fixed on the middle lower portion of the inner wall of the test tube. The middle of the blood separating gel is provided with a through hole of 5-8 mm in the axial direction. Since the turning-over and the movement of the blood separating gel in the middle portion of the test tube are reduced, the centrifugal force and the centrifugal time of separation are reduced, substance in the separating gel is prevented from scattering into blood serum, the blood serum with higher quality can be obtained, and the accuracy of test results can be greatly improved. The vacuum blood taking tube has simple construction and convenient operation and use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and specifically a kind of novel hollow adds the glue vacuum test tube.
Background technology
As everyone knows, at present domestic and international vacuum test tube series all is to adopt the bottom to add the glue mode, promptly adds separation gel in the blood taking tube bottom.In order to prepare high-quality serum, centrifugal is vital link, adopt the horizontal centrifuge, and relative centrifugal force(RCF) will reach 1200-1500g, time 10-15 minute.Because the molecular structure of separation gel, be to form network structure by hydrogen bond association, owing to the reason separation gel of proportion will move to the test tube middle and lower part from the bottom reversed of test tube, this just needs long relatively time and relative big centrifugal action, big centrifugal force, cause the basic substance of separation gel hydrogen bond and separation gel that some destructions can be taken place, the material that has can be distributed in the serum, influences testing result.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of simple structure is provided, easy to use, operate simple and easy, can effectively reduce isolating centrifugal force and centrifugation time, the hollow that improves the result of laboratory test accuracy adds the glue vacuum test tube.
The technical scheme in the invention for solving the above technical problem is: a kind of hollow adds the glue vacuum test tube, form by test tube, blood separating colloid, coagulant, sealing plug, in vitro bottom and inwall scribble coagulant, and it is characterized in that: said blood separating colloid is fixed on the middle and lower part of inboard wall of test tube.
The said blood separating colloid of this utility model is fixed on the inboard wall of test tube apart from test tube bottom 1-3cm place.
Be axially arranged with the through hole of a 5-8mm in the middle of the said blood separating colloid of this utility model.Preferred plan is the through hole that is axially arranged with a 6mm in the middle of the blood separating colloid.
This utility model blood separating colloid is fixed on the middle and lower part of inboard wall of test tube.Against existing technologies, because blood separating colloid has reduced isolating centrifugal force and centrifugation time, relative centrifugal force(RCF) 800g-1100g, time 5-10 minute upset of the middle part of test tube and mobile the minimizing.This utility model simple structure, operation, easy to use.Avoid the material in the separation gel to be distributed in the serum, can obtain higher-quality serum, improved the accuracy of result of laboratory test greatly.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. test tubes among the figure, 2. blood separating colloid, 3. sealing plug, 4. through hole.
The specific embodiment
As can be seen from Figure 1, a kind of hollow of this utility model adds the glue vacuum test tube, is made up of test tube 1, blood separating colloid 2, coagulant, sealing plug 3.Sealing plug 3 is installed in the port position of test tube 1, seals.Test tube 1 can be PET (polyethylene terephthalate) test tube, also can be teat glass, and it is and the supporting standard test tubes of corresponding instrument such as centrifuge.Test tube 1 inner bottom part and inwall scribble coagulant.
Characteristics of the present utility model are: said blood separating colloid 2 is fixed on the middle and lower part of test tube 1 inwall.Specifically be that blood separating colloid 2 is fixed on the inboard wall of test tube apart from test tube bottom 1-3cm place.
Be axially arranged with the through hole 4 of a 5-8mm in the middle of the said blood separating colloid 2 of this utility model.Preferred plan is the through hole 4 that is axially arranged with a 6mm in the middle of the blood separating colloid 2.When being operation, the effect of through hole 4 is convenient to the adding of blood.
This utility model blood separating colloid 2 is fixed on the middle and lower part of test tube 1 inwall.Like this, blood separating colloid is in the upset of the middle part of test tube and move minimizing, isolating centrifugal force and centrifugation time have been reduced, relative centrifugal force(RCF) 800g-1100g, time 5-10 minute, avoid the material in the separation gel to be distributed in the serum, can obtain higher-quality serum, improved the accuracy of result of laboratory test greatly.This utility model simple structure, operation, easy to use.Avoided owing to the excessive material damage that causes of centrifugal force, can high-quality serum.
