Abstract
A kind of mouse or rat vein heparin tube, its composition is made of pipe shaft, more than two part of lid, it is described to be equipped with pipe shaft internal layer, refrigeration interlayer and pipe shaft outer layer successively from the inside to the outside, lid internal projection is equipped with below the lid, cap top center is equipped with hollow rubber portion；The lid is sealed by the nozzle of lid internal projection and pipe shaft set by lid.The utility model is more suitable for trace blood, less blood sample loss, and blood automatically flows into heparin tube, no longer needs to release blood syringe in blood taking needle and collect in 1.5ml centrifuge tubes, reduces the probability of blood clotting and haemolysis；It is two layers inside and outside due to having, it is equipped with refrigerant in interlayer, it is for a period of time using preposition 4 ° of refrigerators, fresh-keeping conducive to blood sample, the degradation of active ingredient in blood sample is reduced, whole device is cheap, easy to use, easy to operate, reduces the pollution of experiment sample.
Description
Technical field
The utility model is related to a kind of mouse or rat vein heparin tubes, belong to experiment equipment technical field.
Background technology
Mouse or rat are a kind of common experimental animals of medical research, and experimenter is often taken a blood sample by orbital venous plexus,
Rat-tail is taken a blood sample and the blood sample of the methods of Culling heart blood acquisition mouse or rat carries out experimental study.Currently, experimenter is normal
It is taken a blood sample to mouse or rat with blood taking needle, since experimental animal body is smaller, blood volume is less, and each blood sampling volume is generally
Between 0.2ml-1.0ml, in each blood collection procedure, blood is trapped in the heparin tube being connected with blood taking needle, so common infusions
The blood being detained in heparin tube is released from the other end of heparin tube and is collected in 1.5ml centrifuge tubes by device.This method acquisition and
Collecting blood sample, there are following drawbacks in the process：1, heparin tube one end of blood taking needle is communicated in the external world, due to the original of atmospheric pressure
Because blood taking needle is more slow from the outflow of the blood of venous drainage, therefore use syringe holder blood sample from heparin tube from collecting
The process time that release is collected into 1.5ml centrifuge tubes is longer, and blood easily solidifies in the heparin tube being connected with blood taking needle, causes to adopt
Sample fails；2, in blood collection procedure, blood enters sample under syringe thrust again by blood taking needle in heparin tube
In collecting pipe, blood haemolysis is easily caused, blood sample is caused to fail；3, since mouse or rat blood sampling volume are usually less than 1ml,
Vacuum blood collection tube currently on the market is mostly 5ml specifications, and use is extremely inconvenient.
Utility model content
The purpose of this utility model is to overcome deficiency in the prior art, to provide a kind of mouse or rat vein
Heparin tube.
A kind of mouse or rat vein heparin tube, its composition are made of pipe shaft, more than two part of lid, it is described from the inside to the outside
It is equipped with pipe shaft internal layer, refrigeration interlayer and pipe shaft outer layer successively, is equipped with lid internal projection below the lid, cap top center is set
There is hollow rubber portion；The lid is sealed by the nozzle of lid internal projection and pipe shaft set by lid.
It is using the advantageous effect of above-mentioned technical proposal：
1. the utility model is more suitable for trace blood, less blood sample loss, blood automatically flows into heparin tube, nothing
Blood syringe in blood taking needle need to be released again and be collected in 1.5ml centrifuge tubes, reduce the probability of blood clotting and haemolysis；
2. plurality of reagents is prefixed in the utility model, such as coagulant, ethylenediamine tetra-acetic acid and its salt, sodium citrate
Deng, a variety of testing requirements of sample can be met, without test before specially to 1.5ml centrifuge tubes do add reagent processing, make
With conveniently；
3. the utility model has two layers inside and outside, it is equipped with refrigerant in interlayer, for a period of time using preposition 4 ° of refrigerators, is conducive to blood
Liquid sample is fresh-keeping, reduces the degradation of active ingredient in blood sample, whole device is cheap, easy to use, easy to operate, subtracts
The pollution of experiment sample is lacked.
Description of the drawings
Fig. 1 is the utility model mouse or rat vein heparin tube structural schematic diagram.
In figure：In 1- pipe shafts, 2- lids, 3- pipe shafts internal layer, 4- refrigeration interlayer, 5- pipe shafts outer layer, 6- lids internal projection, 7-
Heart rubber section.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
A kind of mouse or rat vein heparin tube, as shown in Figure 1：Its composition is made of 2 liang of pipe shaft 1, lid several parts,
It is described to be equipped with pipe shaft internal layer 3, refrigeration interlayer 4 and pipe shaft outer layer 5, for a period of time using preposition 4 DEG C of refrigerators, profit successively from the inside to the outside
It is fresh-keeping in blood sample, the degradation of active ingredient in blood sample is reduced, 2 lower section of the lid is equipped with lid internal projection 6, lid
2 top centers are equipped with hollow rubber portion 7；The nozzle progress that the lid 2 passes through lid internal projection 6 and pipe shaft 1 set by lid 2
Sealing.
1 capacity of the pipe shaft is 1.5ml, and relative to 5ml vacuum blood collection tubes in the market, which is more suitable for micro adopt
Blood, less blood sample loss；The utility model is vacuum blood collection tube, is prefixed a certain amount of negative pressure in process of production, when
After blood sampling pin puncture enters the blood vessels such as mouse orbit vein or tail vein, due to the suction function in heparin tube, blood flows automatically
Enter in heparin tube, no longer needs to release blood syringe in blood taking needle and collect in 1.5ml centrifuge tubes, reduce blood clotting
With the probability of haemolysis；The pipe shaft 1 is plastic material, and whole device is cheap, easy to use, easy to operate, reduces reality
Test the pollution of sample.
The pipe shaft internal layer 3 is prefixed various additives, such as coagulant, ethylenediamine tetra-acetic acid and its salt, sodium citrate
Deng, a variety of testing requirements of sample can be met, it is easy to use without doing the processing of additive before experiment to 1.5ml centrifuge tubes；
It is equipped with refrigerant in refrigeration interlayer 4, it is fresh-keeping for sample.
The utility model practical approach：
First：Heparin tube is set into 4 ° of refrigerators for a period of time using preceding, is pre-chilled for refrigerating layer, when sampling fresh-keeping blood sample
This；
Second：By blood taking needle one end out of, lid hollow rubber partial insertion pipe, due to the suction function in heparin tube,
Blood automatically flows into heparin tube, and after blood sampling, blood taking needle is extracted.
