Description
Technical field
One kind of the present invention takes blood casing, and blood is taken for blood donor's blood bag match blood pigtail more specifically to a kind of
Casing.
Background technology
Currently, legal provisions medical institutions are both needed to before providing red blood cell treatment for clinical patients to receptor and blood donor
Blood carry out cross matching, blood donor's sample be acquire blood after sealing plait preserve sample, blood pigtail for diameter about
0.5cm, 10-20cm elongated shape plastic pipes are about, are to use scissors along next heat seal point first when carrying out cross match blood test
Front end cut, then the tail end in sample is broken, blood is allowed to be flowed into test tube.Blood sample when operation in plait can often flow out
Or it splashes with workbench or staff；Simultaneously as the scissors used directly contacts blood sample, so operating
In the process, needing one bag of blood must disappear to scissors primary poison, or each sample using one scissors, daily handled by blood
Sample is up to hundred bags, so one bag of blood is less feasible scissors using one, current most of medical institutions are all to scissors reality
Enforcement once sterilizing is primary, is sterilized with thimerosal cleaning disinfection or with medicining liquid dipping, in practical operation, often
Due to the too short effect that disinfection is not achieved and requires of disinfecting time, to cause cross contamination.On the other hand, in the mistake using scissors
Cheng Zhong is easy to cause the body of staff potentially possible injury, increases the chance of hospital-acquired infection.
Invention content
To solve the above-mentioned problems, simple in structure the present invention provides one, the blood bag blood pigtail of reasonable design disposably takes
Blood casing.
In order to achieve the above object, specific embodiments of the present invention are as follows：

Casing is equipped with a sharp portion on the inner wall close to nozzle, and the attachment wall of sharp portion and the facing interior wall material of sharp portion design
It is thicker, it prevents from puncturing tube wall in transportational process or use punctures hand in the process, epimere casing and the junction of hypomere casing are set
Count the angled gradient, facilitate blood pigtail that can be directly entered stage casing along pipeline during insertion, in stage casing casing with
A needle tubing is equipped between hypomere casing, the needle tubing fixes the connection that plug is fixed on stage casing casing and hypomere casing by one
Place, hypomere casing also have a needle tubing that hypomere opening direction is exposed to by fixed plug, the needle tubing and the hollow needle tubing in stage casing bottom
It is connected, which is fixedly connected with junction, and needle tubing is fixedly connected with fixed plug, the internal diameter and test tube of the hypomere casing
Nozzle outer diameter match.
In said program, the internal diameter of the epimere casing is bigger than the internal diameter of stage casing casing.
Preferably, the internal diameter of the hypomere casing is bigger than the internal diameter of stage casing casing.
Preferably, the needle tubing is arranged in the center of fixed plug.
Preferably, the internal diameter of stage casing casing is bigger than the outer diameter of blood pigtail.
Preferably, funneling is designed in the junction of the epimere casing and hypomere casing.
Preferably, the length in stage casing can be designed according to the length of blood pigtail.
Preferably, the needle tubing is hollow needle tubing, and the both ends of needle tubing are designed to sharp protrusion structure.
The beneficial effects of the invention are as follows：The present invention is using the completely new casing knot coordinated with blood pigtail and vaccum blood collecting test tube
Structure need not use the method for cutting blood pigtail using scissors that can safely and effectively carry out the collecting work of blood in time, and one, set
Pipe is divided into upper, middle and lower segment, and epimere is to use integrally formed structure, reduces the complexity in blood collection procedure；Two, epimere set
The junction of pipe and hypomere casing is designed to " trapezoidal " or " infundibulate " so that blood pigtail energy much smoother during insertion
Be directly entered stage casing along pipeline, need not be artificial carry out insertion repeatedly and insert out；Three, in stage casing casing and hypomere casing
Needle tubing is arranged in junction, can timely poke blood pigtail and vaccum blood collecting test tube plug, and work that blood was collected improves efficiency, avoids curing
Source sexuality dye；Four, sharp portion is set at the nozzle of epimere casing, effect is to pierce through blood pigtail, passes through the combined use with needle tubing, energy
Preferably so that the blood in blood pigtail sufficiently flows into vaccum blood collecting test tube；Five, in the attachment wall and facing interior wall of sharp portion
Material setting it is thicker, can effectively avoid squeeze sharp portion during puncture finger.

Specific implementation mode
As shown in Figure 1, including that a both ends open (is schemed shaped like dumbbell shaped, hollow transparent casing the present invention provides one kind
1), entirety can be divided into upper, middle and lower segment pipe, 1 bulb opening upwards of epimere casing, and inner wall is fixed at nozzle
One perpendicular to tube wall sharp portion, epimere internal cavities are narrowed to stage casing naturally, to cut-off blood pigtail, stage casing lower lumen and set
Pipe hypomere inner cavity junction close, be secured by it the hollow needle tube in the inner cavity center of circle and communicate, needle tubing be exposed to stage casing casing and
Hypomere casing, hypomere casing are downwardly open (Fig. 2).
A kind of blood bag blood pigtail disposably takes blood casing, which is hollow structure, is divided into upper, middle and lower segment casing, described
Casing both ends open, for the opening of epimere casing 1 to push blood pigtail, epimere casing 1 is equipped with a point on the inner wall close to nozzle
Thorn portion 4, the attachment wall of sharp portion 4 is all provided with the facing interior wall material of sharp portion 4 haggles over thickness, prevents from puncturing tube wall in transportational process
Or hand is punctured during use, the junction of epimere casing 1 and stage casing casing 2 is designed to that certain gradient, stage casing casing 2 are used
With cut-off blood pigtail, casing 2 bottom center location in stage casing has one to fill in 5 needle tubing A6 that are fixed and being exposed to stage casing by fixed,
The needle tubing A6 is arranged in the center of fixed plug 5, stays piercing through blood pigtail juxtaposition and guides blood flow, hypomere in blood pigtail
For the opening of casing 3 with vaccum blood collecting test tube is externally fitted to beyond the Great Wall, 3 center of circle of hypomere casing also has one to be exposed to hypomere by fixed plug 5
The needle tubing B7 of opening direction, needle tubing B7 are connected with 2 bottom needle tubing A6 of stage casing casing, enter vacuum examination to pierce through test tube plug
Guan Zhong.
