Description
Technical field
It the utility model is related to blood sampling test tube, more particularly to a kind of disposal vacuum heparin tube.
Background technology
Vacuum blood collection tube is a kind of heparin tube of negative pressure of vacuum, the material of vacuum blood collection tube:Heparin tube is mostly simple glass
Pipe and plastic tube, a large amount of uses of self-reacting device and the preservation of blood propose higher want to blood sample original traits stability
Ask, make vacuum blood drawing technique breach only for safety requirement, its accuracy, sample original traits, hold time and
The performance indications such as the cooperation of pipe machine, test tube intensity can serve as evaluating the foundation of vacuum blood collection tube quality.
Electrostatic film is a kind of not coating glue film, mainly PE, PVC material, is adhered by product Electrostatic Absorption itself on article
Shield, be typically used for being used for glass, eyeglass is high than more sensitive surface to adhesive or glue residual
The surface of the unusual lights such as light plastic rubber surface, acrylic.
A kind of vacuum blood collection tube, including blood sampling test tube, rubber stopper, skull, the vacuum blood collection are proposed in the prior art
Tube head lid is that one end is flat mouth through hole, and the other end is the plastic tube-shape structure of cone mouth through hole, and skull inwall has a circle flange；Rubber
Plug is installed tightly on blood sampling test tube by skull；The smaller diameter end of the rubber stopper of the vacuum blood collection tube is by skull flat mouth side pressure
Enter skull through hole to be installed tightly in blood sampling test tube, after rubber stopper larger diameter end inserts through hole by skull flat mouth end, in skull
One circle flange of wall blocks rubber stopper larger diameter end, and this heparin tube for single lid type due to designing, such structure
The process vacuumized in a package is inconvenient, and the requirement to encapsulation machine is higher, and not only cost is high, and reduces production
Efficiency.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, adapts to real needs, there is provided a kind of disposable true
Empty heparin tube, to solve, the structure of traditional vacuum heparin tube is too high to vacuum sealing technique requirement to cause cost rise and efficiency to drop
The problem of low.
In order to realize the purpose of this utility model, technical scheme is used by the utility model：
A kind of disposal vacuum heparin tube, including：Pipe shaft and the composite cover for being arranged on pipe shaft openend, the composite cover bag
Enclosing cover and inner cap are included, the inner cap is fixed on around pipe shaft opening, described to cover outside provided with rubber gasket, on the inside of the enclosing cover
It is connected with interior outer side of lid by interference fit mechanisms, interior cover is additionally provided with one layer of diaphragm seal for being enclosed on pipe shaft opening, institute
State central be provided with of diaphragm seal and vacuumize flexible pipe with the horn-like of the film integrated connection of the sealing.
The diaphragm seal is that PE materials are made with the horn-like flexible pipe that vacuumizes.
The interference fit mechanisms include being arranged on the cross section of inner cap outer periphery as the neck of V-type and are arranged on enclosing cover
The bulge loop that inner side coordinates with the neck.
The horn-like flexible pipe that vacuumizes is arranged on the outside of the diaphragm seal.
The beneficial effects of the utility model are：
1. use composite cover, double insurance, it is ensured that test tube interior vacuum is not revealed；
2. vacuum pumping is easy to using diaphragm seal and the horn-like flexible pipe that vacuumizes, after pump housing interface and flexible pipe disengaging,
Flexible pipe ensures the sealed environment of inside because internal negative pressure and electrostatic adsorption can close automatically；
3. easy to operate, compared with traditional heparin tube, during use blood drawing syringe needle need to pierce through successively rubber gasket and
Diaphragm seal, because rubber gasket and diaphragm seal are film, quite convenient for piercing through；
4. exterior and interior cover uses interference fit mechanisms, enclosing cover causes bulge loop to expand by hot environment during encapsulation, and inner cap passes through
Low temperature environment causes neck to tighten, and after recovering normal temperature, exterior and interior cover sealing is stronger, it is difficult to comes off.
In summary, the utility model carries out structure improvement to traditional vacuum blood collection tube, is not influenceing simple operation
On the premise of, strengthen sealing, improve the efficiency of test tube encapsulation, reduce use cost.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model structure sectional view；
Fig. 3 is partial enlarged drawing at A in Fig. 2.
Reference is as follows in figure：
1. pipe shaft；2. composite cover；3. enclosing cover；4. inner cap；5. rubber gasket；6. interference fit mechanisms；7. diaphragm seal；8.
It is horn-like to vacuumize flexible pipe；9. neck；10. bulge loop.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Embodiment 1：
A kind of disposal vacuum heparin tube, referring to Fig. 1, Fig. 2 and Fig. 3, including：Pipe shaft 1 and it is arranged on pipe shaft openend
Composite cover 2, the composite cover 2 includes enclosing cover 3 and inner cap 4, and the inner cap 4 is fixed on around pipe shaft opening, on the enclosing cover 3
Provided with rubber gasket 5, the inner side of enclosing cover 3 is connected with the outside of inner cap 4 by interference fit mechanisms 6, is also set on the inner cap 4
There is one layer of diaphragm seal for being enclosed on pipe shaft opening 7, the center of diaphragm seal 7 is provided with the loudspeaker being connected with the integral type of diaphragm seal 7
Shape vacuumizes flexible pipe 8.
More preferable, the cross section that the interference fit mechanisms 6 include being arranged on the outer periphery of inner cap 4 is the card of V-type
