Abstract
The utility model relates to a dual-layer vacuum blood taking tube, which comprises a test tube and a sealing rubber plug, wherein an inner liner tube is arranged in the test tube, the inner liner tube is inserted into the test tube and is connected and fixed with the test tube through glue, the external wall of the port of the inner liner tube is coated with light-curable adhesive, and is connected and fixed with the test tube through the light-curable adhesive. The vacuum blood taking tube is characterized in that the inner liner tube is arranged in the test tube of the utility model, on the premise of not changing the appearance dimension of the test tube, the volume of a standard vacuum blood taking tube is reduced, thereby effectively reducing the space which is not fully filled with blood, namely a 'dead cavity', the vacuum blood taking tube has simple structure, convenient use and low cost, and improves the accuracy of testing results.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of double-layer vacuum blood taking tube.
Background technology
As everyone knows, usually thrombotest adopts 1.8ml or 2.7ml blood taking tube all to be and the supporting standard vacuum blood taking tube of corresponding instrument such as centrifuge.The top of vacuum test tube has a large amount of is not added full space by blood, is called " dead space ".The thrombotest pipe that domestic and international research shows to be had " dead space " is not suitable for using macromole heparin patient and detects APTT, and " dead space " causes platelet activation, and the hyperamization platelet PF4 factor discharges, so cause the false shortening APTT time.Test shows that this error is that the probability that the random phenomenon that can not expect occurs is approximately 15～22%, because the false shortening APTT time causes doctor's mistake to increase the heparin consumption, thereby causes hemorrhage serious consequence.
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, with low cost, under the prerequisite that does not change the test tube apparent size, can effectively not reduce and added full space, improve the double-layer vacuum blood taking tube of result of laboratory test accuracy by blood.
The technical scheme in the invention for solving the above technical problem is: a kind of double-layer vacuum blood taking tube, it includes test tube, sealing plug, it is characterized in that: in vitro be provided with an internal lining pipe, internal lining pipe is inserted into that blended rubber and test tube are connected and fixed in the test tube.
The said internal lining pipe outer wall of this utility model is provided with an air discharge duct that axially connects.
The said internal lining pipe port outer wall of this utility model scribbles optic-solidified adhesive, is connected and fixed by optic-solidified adhesive and test tube.
This utility model in vitro is provided with an internal lining pipe, under the prerequisite that does not change the test tube apparent size, reduced the volume of standard vacuum blood taking tube, can effectively not reduce like this and added full space by blood, i.e. " dead space ", against existing technologies, this utility model simple structure, easy to use, with low cost, improved the result of laboratory test accuracy.
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. internal lining pipe, 3. sealing plug.
The specific embodiment
As can be seen from Figure 1, a kind of double-layer vacuum blood taking tube of this utility model, it comprises compositions such as test tube 1, 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, and it is and the supporting standard test tubes of corresponding instrument such as centrifuge.
Characteristics of the present utility model are to be provided with an internal lining pipe 2 in the test tube 1.Internal lining pipe is PP (polypropylene) materials processing.Internal lining pipe 2 is inserted into that blended rubber and test tube are connected and fixed in the PET test tube 1.For the convenience of assembling, reliable, said internal lining pipe 2 outer walls are provided with an air discharge duct that axially connects, so that in time discharge the gas in the PET test tube 1.
The said internal lining pipe 2 of this utility model is connected and fixed by UV glue and test tube.Specifically be that internal lining pipe 2 port outer walls scribble photocuring (UV) glue, be connected and fixed by photocuring (UV) glue and test tube.Photocuring (UV) glue solidifies in the short time at the utmost point under the irradiation of high intensity UV A Burdick lamp, reaches best solidification effect.
This utility model is provided with an internal lining pipe in it under the prerequisite that does not change the test tube apparent size, like this, reduced the volume of standard vacuum blood taking tube, can effectively not reduce and is added full space by blood, be i.e. " dead space ".Avoided " dead space " to cause the platelet activation and the platelet PF4 factor to discharge, suitable application macromole heparin patient detects APTT.This utility model simple structure, easy to use, with low cost, improved the result of laboratory test accuracy greatly.
