Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to specification text
Word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of individual other elements or its combination.
" on " " under " used in this case be in order to which character express understands and uses, the restriction being not offered as on direction,
It is interpreted as：Using upper shell side to be upper, under lower house side is.
A kind of way of realization according to the present invention is following figures illustrated, including：Shell, by insertion pore structure
Upper and lower casing pressing form, the upper shell lower end inner wall is provided with some grooves, lower house upper end outer wall provided with and institute
It is raised correspondingly to state groove, the groove forms integrative-structure with raised be fitted close, by tongue and groove pressing structure
Difficulty of processing can be reduced, structure is reliable；And seal assembly, in the accommodating cavity of upper shell formation, the sealing
Component includes sealing-plug and the sealing gasket located at the sealing-plug lower end, and the sealing-plug is provided with runner along central axial line, described
Sealing-plug is provided with the first circular protrusions towards the center of upper shell upper port side, and first circular protrusions go out liquid with syringe
End structure matches, and offers the first otch in first circular protrusions, it is communicated with the runner, and nurse is squeezed using syringe
At the top of densification blocking during convex shaped arc, convex shaped arc and the sealing of syringe inner hole are more preferable, prevent leaked liquid from remaining, and institute
The second otch that the runner other end is stated with sealing gasket center communicates, and second otch, which is located at, is located at the sealing gasket direction
In second circular protrusions of the side wall centers of lower house side；Wherein, be provided with mozzle in the lower house, the mozzle and
Second otch communicates.
The sealing-plug is formed in one structure, can still be used beneficial to after sealing-plug extrudes repeatedly, reliability carries
It is high.
The sealing-plug includes, extruded segment, and in cylindrical type entity structure, the extruded segment is located at the upper shell upper port
Interior, first circular protrusions are located at top surface in the extruded segment；Section is bored, hollow structure, the section of boring is from the extruded segment bottom
End extends downwardly, and the cone section outer wall is brought into close contact to be formed in the conical surface that gradient is 30 °, the cone section with the upper enclosure inner wall
Jam-packed state；Matrix part, extended downwardly from the cone section bottom, described matrix portion is in hollow circular cylinder structure；Wherein, the stream
Road is made up of the accommodating cavity connection in the cone section and described matrix portion, still may be used beneficial to after sealing-plug extrudes repeatedly

Sterilized in Reusability cotton swab, will not as in the market product plane it is recessed it is heavy be not easy to sterilize, easily miss；Because sealing gasket uses
Convex shaped arc designs, and after liquid is extruded, can close otch in time, prevent extraneous bacterium from entering infected patient blood..
Technological merit：
1., substitution ultrasonic wave, by physical engagement between plastics, can easily realize automated production, improve production effect
Rate, reduce product cost.
2., plug construction design, the optimal rebound reset design of specific golden section is small according to sealing-plug experiment detection 48
When extrude for a long time, remain able to reset, accomplish according to effective, avoid unconventional use cause to reset failure it is possible.
3., convex shaped arc at the top of sealing-plug, effect is when nurse uses after syringe extruding, and syringe 6:100 endoporus
Fitted seal is more preferable, prevents leaked liquid from remaining, and cut is just opened from center in extrusion process, and cut will not be excessive too small,
And can be good at playing sealing effectiveness after convex shaped arc reset, the cut vestige of cutter die cutting is can't see on surface.In the market mesh
There is very long cut at preceding obvious center, substantially has gap after some Reusabilities, can pollute.
4., at the top of sealing-plug during convex shaped arc nurse's Reusability can cotton swab sterilization can play very good effect, will not picture
Recessed sink of in the market product plane is not easy to sterilize, and easily misses.
Operation principle：
Nurse is in use, with syringe 6:At 100 extruding F, now liquid medicine is passed through by the cut at F by passage at G
Cut at H is opened in fluid pressure extruding, and liquid medicine is flowed into woven hose.
1., overall structure form
2., gasket, disk center spill, convex, middle cut.
3., sealing plug, convex-concave circular arc or cylindricality at the B of top.
4., height, angle at sealing-plug C, D, parameter area.
5., male screw socket H and female screw socket G coordinate the concave-convex type muscle connection and sealing cooperation of F places.
Comparative example：Serious problem on deformation occurs after continuously injection 24h in existing sealing-plug, it is difficult to resilience, it is actual
Using potential safety hazard being present, compared with this sealing-plug, after sealing-plug that this patent is provided continuously injects 24h, resilience is good
Good, injection risk substantially reduces.
Although embodiment of the present invention is disclosed as above, it is not restricted in specification and embodiment listed
With.It can be applied to various suitable the field of the invention completely., can be easily for those skilled in the art
Realize other modification.Therefore it is of the invention and unlimited under the universal limited without departing substantially from claim and equivalency range
In specific details and shown here as the legend with description.
