Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of lower resistance electron injector.
Background technology
Syringe is made up of the foraminate syringe of front end band and the piston push rod that matches.Syringe is used for a small amount of liquid or its to be injected into region that other method cannot be close or locally extracts out from those.When push rod is extracted, liquid or gas suck from syringe front end aperture, liquid or gas are extruded when push rod pushes.Injection is called by this process of syringe and syringe needle extraction or injecting gas or liquid.
Piston push rod is made up of push rod and plug.Plug plays very important effect in syringe construction, when piston push rod uses in push-and-pull, due to the relation that air pressure changes, extremely can require great effort, push rod and plug easily can be made because of carelessness to come off, dally over one's work, also can affect the life security of patient time serious.
Summary of the invention
The technical problem that this utility model mainly solves is to provide a kind of lower resistance electron injector, there is the sealing ring that can reduce frictional force, it is simply convenient when user can be allowed to use, plug inside is provided with anti-drop structure, plug is connected with push rod more stable, adds convenience and the safety of syringe use.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is: provide a kind of lower resistance electron injector, comprise: rubber plug body, plug chamber and cock cap, the front end of described rubber plug body is provided with cock cap, the inside, rear end of described rubber plug body is provided with plug chamber, the junction of described rubber plug body and cock cap is provided with the first sealing ring, and the surface of described rubber plug body is provided with the second sealing ring, and described plug intracavity portion is provided with the first resist delamination and the second resist delamination.
In this utility model preferred embodiment, the longitudinal section of described cock cap is U-shaped or up-narrow and down-wide trapezoidal.
In this utility model preferred embodiment, the surface of described first sealing ring is provided with the first otch.
In this utility model preferred embodiment, the degree of depth of described first otch is less than the thickness of the first sealing ring.
In this utility model preferred embodiment, between described second sealing ring and rubber plug body, be provided with the second otch.
In this utility model preferred embodiment, the longitudinal section of described second otch is triangle.
In this utility model preferred embodiment, the longitudinal section of described first resist delamination and the longitudinal section of the second resist delamination not reciprocity.
The beneficial effects of the utility model are: have the sealing ring that can reduce frictional force, it is simply convenient when user can be allowed to use, plug inside is provided with anti-drop structure, plug is connected more stable with push rod, adds convenience and the safety of syringe use.

In order to be illustrated more clearly in the technical scheme in this utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the vertical section structure schematic diagram of lower resistance electron injector one of the present utility model preferred embodiment;
In accompanying drawing, the labelling of each parts is as follows: 1, the first otch, and 2, cock cap, the 3, first sealing ring, 4, rubber plug body, the 5, second sealing ring, the 6, second resist delamination, the 7, first resist delamination, the 8, second otch, 9, plug chamber.
Detailed description of the invention
Be clearly and completely described to the technical scheme in this utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of this utility model protection.
This utility model embodiment comprises:
A kind of lower resistance electron injector, comprise: rubber plug body 4, plug chamber 9 and cock cap 2, the front end of described rubber plug body 4 is provided with cock cap 2, the longitudinal section of described cock cap 2 is U-shaped or up-narrow and down-wide trapezoidal, the inside, rear end of described rubber plug body 4 is provided with plug chamber 9, described rubber plug body 4 is provided with the first sealing ring 3 with the junction of cock cap 2, and the surface of described rubber plug body 4 is provided with the second sealing ring 5.
In addition, the surface of described first sealing ring 3 is provided with the first otch 1, the second otch 8 is provided with between described second sealing ring 5 and rubber plug body 4, the degree of depth of described first otch 1 is less than the thickness of the first sealing ring 3, the second otch 8 is provided with between described second sealing ring 5 and rubber plug body 4, the longitudinal section of described second otch 8 is triangle, the sealing ring extended out can ensure the sealing between syringe cylinder and piston push rod, prevent medicinal liquid from flowing out, and adopt 2 sealing rings, further guarantee increases sealing, also decrease the frictional resistance between syringe cylinder and piston push rod as much as possible simultaneously, make user easy to use.
In addition, inside, described plug chamber 9 is provided with the first resist delamination 7 and the second resist delamination 6, the longitudinal section of described first resist delamination 7 and the longitudinal section of the second resist delamination 6 not reciprocity, resist delamination can increase the connectivity that push rod inserts plug intracavity and rubber plug body 4, ambassador's push rod of can not exerting oneself in drawing liquid process is separated with rubber plug body 4, add medical safe, decrease malpractice.
The beneficial effect of this utility model lower resistance electron injector is:
Have the sealing ring that can reduce frictional force, simply convenient when user can be allowed to use, plug inside is provided with anti-drop structure, plug is connected more stable with push rod, adds convenience and the safety of syringe use.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
