Description
Technical field
The utility model relates to the rubber stopper technical fields in Key works Drug packing, and in particular to a kind of anti-glue of raising one's hat of heparin tube
Plug.
Background technique
The basic structure of vacuum blood collection tube includes tube body, rubber plug and pipe cap in the prior art, and the colouring discrimination of pipe cap indicates
Blood sampling classification.The rubber plug of heparin tube generally includes plug neck and corking portion, and the external profile diameter in corking portion is greater than the outer rim of plug neck
Diameter, plug neck cooperation are filled in tube cavity of taking a blood sample, and corking portion lid is located on the nozzle of heparin tube tube body, using plug neck and is adopted
Sealing effect is realized in press between blood vessel side wall.The inner surface of pipe cap side wall is usually provided with bulge loop, which is used for and glue
The concave ring of outer surface matches, and can assemble pipe cap the characteristics of deformation resilience using rubber plug, and guarantee pipe cap and rubber plug and pipe
Stable connection between body.
Rubber plug for vacutainer in the prior art is as described in CN203953673U, CN201814583U, CN201631206U
, the corking portion peripheral side in above-mentioned three kinds of schemes is smooth surface, and the bottom surface outer rim in corking portion protrudes from the week of tube body
To side wall, the bulge loop of pipe cap is snapped onto below the bottom surface outer rim in corking portion.Above-mentioned rubber plug structure has the disadvantage that first,
Since the bottom end in corking portion is solid cylindrical, when assembling vacuum blood collection tube, pipe cap side wall bulge loop extrusion plug cover bottom end, bulge loop
Opposing compression active force between corking portion is larger, it is therefore desirable to cooperate biggish assembling pressure；Second, rubber plug for vacutainer with
Blood directly contacts, and is high pollution medical instrument, needs burning disposal, the corking portion consumption of raw materials amount of solid shape is larger, cost
It is higher.
Summary of the invention
The purpose of the utility model is to overcome defects existing in the prior art, provide a kind of anti-glue of raising one's hat of heparin tube
Plug, corking portion use the integral connecting structure of capping section and changeover portion, and wherein transition section surface is that several raised lines are combined into
Zigzag, utilize the mechanics booster action of raised line, it is ensured that the intensity in cock cap portion, reduce cock cap portion consumption of raw materials amount.
Realize above-mentioned technical effect, the technical solution of the utility model are as follows: a kind of anti-rubber plug of raising one's hat of heparin tube, including plug neck
Portion and corking portion, the top surface for filling in neck are connect with the bottom surface integral type in corking portion, and puncture blind hole is provided in corking portion；
It is characterized in that, corking portion includes capping section and changeover portion, changeover portion be integrally disposed upon capping section and plug neck it
Between, the circumferential side wall of capping section is curved, it is uniformly distributed in the circumferential side wall of changeover portion and is provided with several raised lines, raised line
It is axial with plug neck and corking portion it is axial consistent, the top surface outer profile diameter of changeover portion is equal to or slightly less than the bottom of capping section
Face diameter.
The top of raised line is connect with capping section bottom surface in above structure, and the bottom end outer profile of raised line protrudes from heparin tube tube body
Nozzle, i.e., under heparin tube, rubber plug and pipe cap assembled state, raised line is matched with the bulge loop in pipe cap, and pipe cap is prevented to be detached from.It is convex
Recessed portion between item makes raised line have certain deformation space, and it is de- that the reinforcing rib effect of raised line itself facilitates increase pipe cap
Difficulty from assembly heparin tube.
Due to the recessed portion between raised line there are channel-shaped, in the prior art compared with the rubber plug of model, above-mentioned knot
The usage amount of the rubber plug raw material halogenated butyl rubber of structure is less.
Changeover portion top surface outer profile is equal to or slightly less than the basal diameter of capping section, and the purpose of above structure is, really
The top for protecting raised line is fully connected with capping section, bearing surface of the bottom surface of capping section as raised line.
Preferred technical solution is to fill in the top outer rim of neck to be provided with concave ring, and the concave ring is used for and heparin tube tube body
Nozzle match.It fills in and is generally mated rotating down pressing when assembling between neck and internal wall of pipe orifice for interference fit, rubber plug and nozzle
Movement, concave ring can reduce the area of interference fit, but the too short stability for being unfavorable for assembly of the length for filling in neck, thus on
The pressing force of assembly can be reduced under the premise of guaranteeing to fill in neck length by stating structure.
Preferred technical solution is to protrude from the circumferential direction of corking portion the bottom surface outer rim and changeover portion outer profile of plug neck top surface
Angle between side wall is greater than 90 °.Angle in above structure is usually 100~130 °, plug neck sidewall and corking portion outer rim
Between chamfered shape, convenient for short vulcanization demould.In addition, the concave ring thickness being combined between corking portion outer rim and nozzle increases,
Bulge loop thickness and height of projection with sleeve cap inner surface can also be increase accordingly, can be into since the material of pipe cap is plastics
One step increases the disengaging difficulty of pipe cap in assembly heparin tube.
In order to form chamfering convenient for vulcanization demoulding, preferred technical solution is the groove between adjacent raised line and capping section
The first chamfering is provided between bottom surface.
Preferred technical solution is that the cross section of raised line is to be not more than selected from V-type, the V-arrangement of angle rounding off, central angle
One of 180 ° of discount vibram outlet shape, half elliptic, parabola shaped.It is further preferred that the cross section of raised line is the round and smooth mistake of angle
The V-arrangement crossed.
For the ease of puncturing the vulcanization demoulding at blind hole, preferred technical solution is to puncture the bottom end of blind hole to extend to plug
In neck, the bottom surface for puncturing blind hole is provided with the second circumferential chamfering.
Advantages and beneficial effects of the utility model lie in that
The anti-rubber plug of raising one's hat of the heparin tube is structurally reasonable, and using the corking portion of segmented, the circumferential side wall of capping section is smooth
Curved surface, the circumferential side wall of changeover portion are several raised line compositions, and the end of raised line is connect with capping section, utilize the reinforcing rib of raised line
Effect, the Assembly stability of optimization changeover portion bottom surface outside and pipe cap inner surface bulge loop, reaches anti-and raises one's hat and reduce rubber raw materials
The effect of consumption.
