Description
Technical field
This utility model relates to a kind of safety injector and accessory thereof, relates in particular to a kind of safety injector and push rod thereof.
Background technology
For avoiding to the input of the mankind or animal or cross infection takes place when taking out medium, hypodermic syringe must disposable use, after use promptly as garbage disposal.Use at present maximum disposable syringes to form by cavity overcoat, syringe needle and the journey piston of deciding that is assemblied in the overcoat.The existing greatest problem of this syringe is after injection finishes, its syringe needle is still stayed the outside, not only for the carrying of syringe rubbish, destroy and make troubles, simultaneously may be because of stabbing medical personnel accidentally, cause the secondary cross infection of pathogenic bacteria, become the medical hidden danger that to ignore, so occurred retractable needle on the market and go into disposible safety syringe in the overcoat.The retraction of the needle point of this kind safety injector is to realize by the manual post-tensioning of push rod, for avoiding overexerting push rod pulled out from overcoat and to cause syringe needle to expose, simultaneously also make the needle pierces overcoat and expose, generally all between the endoporus afterbody of overcoat and push rod, be provided with buckle lock structure for fear of pushing back.But, because push rod is long, if the buckle lock structure padlock is undesirable, when the power of back pulling-pushing rod is excessive, just needle seat might be pulled out from overcoat, cause syringe self-destruction failure, not only bring potential safety hazard, also reused by the lawless person easily simultaneously to offal treatment.
The utility model content
First purpose of the present utility model provides a kind of push rod that can effectively avoid push rod and the reusable safety injector of safety injector.
The technical scheme that realizes first purpose of this utility model is a kind of push rod of safety injector, comprises the body of rod, also comprises the centring ring that is arranged on body of rod upper end and the platform that fractures; The described platform middle part that fractures is provided with through hole, and the platform that fractures adopts thin-walled to be connected with the junction of centring ring.
The described platform that fractures is arranged on the top or the below of centring ring.When the platform that fractures is positioned at the top of centring ring, also comprise the support chip that the lower end is connected with the centring ring upper surface.
The described platform that fractures is monoblock type or is multiple-piece.
Be provided with groove bottom described fracture platform inwall or the outer wall.
The described groove that fractures is an oblique groove.
Another technical scheme is: a kind of push rod of safety injector, comprise the body of rod, and also comprise the platform that fractures that is arranged on the body of rod; The described platform middle part that fractures is provided with through hole, and the top and bottom of the platform that fractures adopt thin-walled to be connected with the junction of the body of rod.
The described platform that fractures is monoblock type or is multiple-piece.
The described junction that fractures platform inwall or the outer wall and the body of rod is provided with groove.
The groove of the described platform that fractures is an oblique groove.
Second purpose of the present utility model provides a kind ofly can effectively avoid reusable safety injector.
The technical scheme that realizes second purpose of this utility model is a kind of safety injector, adopts the push rod of aforementioned structure.
After having adopted technique scheme, the utlity model has following beneficial effect: (1) push rod of the present utility model is provided with the interconnective platform that fractures and directly is connected with the body of rod with the centring ring or the platform that fractures, owing to be that thin-walled connects, junction point can easily disconnect, so just can guarantee that syringe promptly goes out of use after use, can not be repeated to use.
(2) platform that fractures of the present utility model can be positioned at the top or the below of centring ring, and the platform that fractures also can be monoblock type or multiple-piece, and groove can be arranged on the inwall or the outer wall of the platform that fractures, so structure is various, and the range of choice is big.
(3) when the platform that fractures of the present utility model is positioned at the top of centring ring, can also support chip be set in the centring ring upper surface, leave the slit between the lower surface of support chip and bowl-type bar wing, when assembling promotes forward, the lower surface of bar head contacts with the upper surface of the platform groove that fractures, support chip props up the lower surface of bowl-type bar wing, and the thin-walled place is stressed very little, and push rod is firm in the time of can guaranteeing to assemble forward more.
(4) pusher structure of the present utility model is simple, and cost of manufacture is low.
(5) after safety injector of the present utility model adopts easily broken push rod of the present utility model, can guarantee that syringe becomes real safety injector.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, this utility model is described in further detail, wherein below
Fig. 1 is a structural representation of the present utility model.
Among the figure:
The body of rod 1, centring ring 2, the platform 3 that fractures, through hole 31, support chip 4.
The specific embodiment
(embodiment 1)
See figure
The push rod of a kind of safety injector of present embodiment comprises the body of rod 1, and is arranged on the centring ring 2 of the body of rod 1 upper end and the platform 3 that fractures.The platform 3 that fractures is as a whole, be arranged on the top of centring ring 2, its middle part is provided with through hole 31, when the assembling syringe, the bottom of bar head will be limited in the through hole 31, the platform 3 that fractures adopts thin-walled to be connected with the junction of centring ring 2, and the inwall bottom of the platform 3 that promptly fractures is groove, and the shape of groove does not limit, platform 3 is extremely thin with the junction of the upper surface of centring ring 2 as long as fracture, groove in the present embodiment is an oblique groove, and the platform 3 that fractures like this is connected with the approximate point in the upper surface of centring ring 2, is easy to during switch out disconnect, but when pushing away forward, can't break, therefore can satisfy the user demand of push rod, simultaneously such structure fabrication is also very convenient.
After syringe is finished using, holding the body of rod 1 pulls back push rod, buckle lock structure by push rod and overcoat, push rod will be limited in the overcoat, can not pull out and to push, pull push rod then, push rod will disconnect from the oblique groove of the platform 3 that fractures and the junction of centring ring 2, so just can thoroughly stop syringe and be reused by the lawless person.
