Abstract
The invention discloses a double-layer gas-protection vacuum blood collection tube. The double-layer gas-protection vacuum blood collection tube comprises a tube body and a sealed rubber plug, the tube body comprises an outer tube and an inner tube, the outer tube and the inner tube are formed integrally in an injection-molding mode, the upper end of the outer tube is higher than that of the inner tube, and an interlayer cavity is formed between the outer tube and the inner tube; the side wall of the sealed rubber plug is provided with multiple rounds of elastic bulge loops, the sealed rubber plug is clamped with the inner wall of the outer tube through the bulge loops in a sealed mode, the diameter of the bottom end of the sealed rubber plug is the same as that of the inner tube, and the sealed rubber plug stretches into the inner tube and is buckled with the inner tube. According to the double-layer gas-protection vacuum blood collection tube, by arranging the outer tube and the inner tube which are formed into one in the injection-molding mode, and connecting a crimpling short tube to the lower end of the inner tube, the blood volume of a vacuum blood collection tube can be accurately controlled, the sealing property between the sealed rubber plug and a single tube can be improved, and the expiration date of the vacuum blood collection tube is prolonged.
Description
Technical field
The present invention relates to a kind of vacuum test tube, particularly a kind of double-layer gas shield vacuum test tube.
Background technology
The venous transfusion equipment used on hospital clinical is a lot, which includes vaccum blood collecting test tube.In clinical blood sampling, some detection projects use anticoagulated blood because needing, therefore often a certain amount of anti-coagulants are prestored in vaccum blood collecting test tube, so the blood flow volume to taking has strict requirements, blood flow volume must be accurate.When grasping bad during blood sampling, it may appear that the more or less phenomenon of blood, solidification is then easy to when blood is more, it is impossible to detect, blood then affects testing result when few.In addition, conventional vacuum heparin tube is in use, traditional single tube structure is easier to crush, and the sealing property between the seal rubber plug and single tube of single tube is bad.
The content of the invention
The technical problem to be solved is to provide a kind of double-layer gas shield vacuum test tube, can accurately control the blood flow volume of vaccum blood collecting test tube, and improves the sealing property between sealing plug and single tube, extends the vacuum test tube shelf-life.
To solve above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of double-layer gas shield vacuum test tube, including body and seal rubber plug, the body includes outer tube and inner tube, and outer tube and inner tube are molded into an entirety, and make outer tube upper end be higher than that interlayer cavity is provided between inner tube and outer tube and inner tube；The side wall of the seal rubber plug is provided with multi-turn elasticity bulge loop, and seal rubber plug seals clamping by bulge loop and outer tube wall, and seal rubber plug bottom diameter is identical with diameter of inner pipe and extend into fastening in inner tube.
Described seal rubber plug is externally provided with cap, with cross section is T-shaped locating part on cap inwall, and the crosspiece of locating part is partially submerged in the groove of seal rubber plug, and perpendicular section and the cap sidewall of locating part form cavity, and cavity is by the clamping of outer tube upper end.
Described inner tube lower end tightens short tube outer wall and is provided with and portray line to tighten short tube.
Also it is uniformly provided with described outer tube and portrays line.
A kind of double-layer gas shield vacuum test tube of the present invention, with following technique effect：
1）, tighten short tube and portray line by arranging, and be also uniformly provided with outer tube and portray line（Dividing for line is portrayed on inner and outer pipes can be determined according to anti-coagulants in experiment in advance with the optimum volume ratio of blood.）During blood sampling, line can be portrayed clear from required blood volume by observation, disposably complete the blood sampling work of anticoagulated blood, improve efficiency.
2）, by arranging injection all-in-one-piece outer tube and inner tube, on the one hand can more preferable air-isolation, heat-insulated, extend the shelf-life of vacuum test tube anticoagulated blood, on the other hand, two pipe protections can be formed and sealed（It is together that, by the elastic bulge loop of seal rubber plug and outer pipe clamp, another road is by seal rubber plug lower end and interior pipe clamp）, so thoroughly outside air can be completely cut off, sealing property is greatly improved.
3）, by arranging the cap with T-shaped locating part, can block seal rubber plug, it is convenient when in use to take out seal rubber plug, prevent seal rubber plug and capping release.

Specific embodiment
As shown in Figure 1; a kind of double-layer gas shield vacuum test tube; including body 1 and seal rubber plug 2; the body 1 includes outer tube 3 and inner tube 4; outer tube 3 and inner tube 4 are molded into an entirety; and the upper end of outer tube 3 is made higher than being provided with interlayer cavity 5 between inner tube 4 and outer tube 3 and inner tube 4, so can preferably air-isolation, heat-insulated, the shelf-life of prolongation vacuum test tube anticoagulated blood；The side wall of the seal rubber plug 2 is provided with multi-turn elasticity bulge loop 6, and, by bulge loop 6 and the inner wall sealing clamping of outer tube 3, the bottom diameter of seal rubber plug 2 is identical with the diameter of inner tube 4 and extend into fastening in inner tube 4, can so form the sealing of two pipe protections for seal rubber plug 2（It is together that, by the elastic bulge loop of seal rubber plug and outer pipe clamp, another road is by seal rubber plug lower end and interior pipe clamp）, so as to outside air be completely cut off, sealing property is greatly improved.
Described seal rubber plug 2 is externally provided with cap 7, with cross section is T-shaped locating part 8 on the inwall of cap 7, and the crosspiece of locating part 8 is partially submerged in the groove of seal rubber plug 2, and perpendicular section and the side wall of cap 7 of locating part 8 form cavity, and cavity is by the upper end clamping of outer tube 3.Thus structure, can block seal rubber plug, convenient when in use to take out seal rubber plug, prevent seal rubber plug and capping release.
Described inner tube lower end tightens short tube outer wall and is provided with and portray line 10 to tighten short tube 9.Thus structure, during blood sampling, can portray line clear from required blood volume by observation, disposably complete the blood sampling work of anticoagulated blood, improve efficiency.
Also it is uniformly provided with described outer tube 3 and portrays line.Coordinate with the line 10 of portraying tightened on short tube, the volume ratio for being worth to optimal blood and anti-coagulants portrayed on line is surveyed by observation.
