Description
Technical field
The utility model relates to the field of medical instrument technology, more particularly, to a kind of adopting with blood specimen collection device
Blood bag.
Background technique
Existing blood taking bag by Blood Transfusion Services to blood testing after, be sent to blood used in clinic mechanism, the blood transfusion of blood used in clinic mechanism
Section or blood bank need collecting blood sample to carry out the test such as blood group and match, but blood bag is a kind of closed structure, defeated in patient
Forbid the blood in method acquisition blood bag in any manner before note, thus the blood in heparin tube is just at production blood specimen
Optimal path.Heparin tube one end connects blood bag, and the other end connects blood taking needle, general to require first to use blood before blood collection starts
The Precerving liquid wetting blood sampling pipe with anti-coagulants in bag, with guarantee in blood collection procedure blood can in pipeline proper flow
And the probability of blood clot generation is reduced, operator can be with heat-sealing machine by heparin tube thermal synthesis several segments after blood collection
Pipeline liquid injecting device, since the pipeline of the Precerving liquid rinse with anti-coagulants is rinsed through the blood of blood donor, anticoagulant ingredient is almost clear
It washes totally, remaining anti-coagulants quantitative change is low in pipeline, there is grumeleuse generation when causing in pipeline.Existing sample reception mode is by blood bag
Coding is taken one off from blood bag and is posted on teat glass, intercepts one section of pipeline liquid injecting device from blood bag heparin tube, cuts off pipe with scissors
The one end on road is put into test tube, then cuts off other end, and the blood in pipeline is pressed onto test tube by pipeline both ends barometric pressure difference
In.But above-mentioned traditional blood taking bag is used, there is following defects: 1, having the case where grumeleuse to happen occasionally in heparin tube, lead
Cause blood to be difficult to flow out, can only squeeze compressing pipeline by force flows out blood, be easy to cause sample hemolysis in this way, testing inspection without
Method uses；2, since grumeleuse consumes a large amount of blood plasma, cause plasma content after centrifugation very low, follow-up test detection can not be carried out；
3, when some grumeleuses that can not visually differentiate are stayed in sample, the sample needle of detection instrument and equipment can be blocked by grumeleuse, be caused
Instrument failure；4, blood sample, which leaves and takes process, has the unexpected risk for scratching blood bag using scissors, and after scissors one blood bag of every operation
Will carry out cleaning operation, so as not to next blood bag operation pollute, operating process be inconvenient with it is cumbersome.5, blood is left and taken
Sample process blood sample pipeline built on the sand, has the wind for being detached from test tube with the open pipeline both ends process pipeline of scissors in conjunction with blood sample test tube
Danger.It researches and develops one kind and is not easy haemolysis, do not generate blood sample clot, blood plasma consumes less, blood retains simplicity, guarantees that blood sample detection is quasi-
The really reliable blood taking bag for having blood specimen collection device, is that the art currently needs to complete task.
Summary of the invention
The purpose of this utility model is to provide one kind to be not easy haemolysis, does not generate blood sample clot, blood plasma consumes less, blood stays
Simplicity is deposited, guarantees that blood sample detection accurately and reliably has the blood taking bag of blood specimen collection device.
In order to achieve the above object, the technical scheme adopted by the utility model is a kind of fill with blood specimen collection
The blood taking bag set, by blood taking bag, heparin tube, blood taking needle, the first air bag, the second air bag；It first heparin tube cropper and second adopts
Blood vessel cropper composition, its main feature is that: heparin tube is sealedly connected on the blood taking bag, the other end of heparin tube is dynamic to be fitted through
Blood taking needle is connected after the hollow tubular body of first heparin tube cropper and the second heparin tube cropper, in first and second heparin tube
It is sealed on heparin tube between cropper and the first air bag is installed, on the heparin tube between the second heparin tube cropper and blood taking needle
Sealing the second air bag of installation；Hollow tubular body one end of the first heparin tube cropper is the tapered conical pipe of diameter, tube wall
There are one section of symmetrical longitudinal slot in port two sides, and the corresponding tube wall of longitudinal slot is equipped with circumferential, external thread, cooperates on external screw thread
Locking nut moves cooperation on hollow tubular body other end round tube and is cased with swivel becket, and swivel becket is equipped with boss, has on boss vertical
The flat through slot of circumferential direction, cooperation insertion blade is moved in through slot, the elbow of blade tip is supported by the limit film on boss, the second blood sampling
Pipe cropper structure is identical as the first heparin tube cropper structure.
The length of the heparin tube is 1000-1100mm, outer diameter 5mm, internal diameter 3.2mm.
First air bag is located at the nearly bag end 550mm of heparin tube, and the second air bag is located at nearly bag end 1000mm.
The volume of first air bag is 5ml, and the volume of the second air bag 6 is 10ml.
Between the blood taking bag and the first heparin tube cropper, between the first air bag and the second heparin tube cropper, second
The heat seal knot of heat-sealing machine hot pressing is respectively equipped on heparin tube between air bag and blood taking needle.
When the utility model is used, blood flows directly into blood taking bag simultaneously due to the alternate position spike between blood donor's position and blood taking bag
It is mixed with Precerving liquid anticoagulant in bag, after blood is full of blood taking bag, blood is also simultaneously filled in heparin tube, in adopting for blood taking needle root
Heat seal knot is made by heat-sealing machine on blood vessel, truncation separation abandons blood taking needle after closing heparin tube, then presses the second air bag, will
After blood in pipeline is all pressed into blood taking bag, unclamp the second air bag, using generation negative pressure by blood bag through anticoagulant blood
Again after filling blood sampling pipe, other two heat seal knot is made respectively, and heparin tube is divided into two sections of closed tube bodies, sliding second
For heparin tube cropper to appropriate location, rotating locking nut makes longitudinal slot on hollow tubular body gradually taper up and lock blood sampling
Pipe, pushes limit film support aside and by bottom knife, and heparin tube is truncated in rotary motion ring, and the exposure port of heparin tube and cropper is inserted
Enter blood sample test tube, press the second air bag, detects blood inflow blood sample test tube in heparin tube.Similarly, the first heparin tube is cut
Blood preparation in heparin tube can be flowed into another blood sample test tube and carry out second of Blood grouping by the setting of disconnected device.
The advantageous effects of principle due to the above structure, the utility model are: collected blood preparation is not
Easy haemolysis does not generate blood sample clot, and blood plasma consumes less, blood retains simplicity, simplifies the work of blood taking bag blood specimen collecting
Step avoids guaranteeing the quasi- using safe and blood sample detection of detection device because scratching blood taking bag due to contaminated blood sample
It is really reliable, reach goal of the invention.
