Description
Technical field
Technical field of medical instruments is the utility model is related to, is specially that a kind of need not return covers needling prevention injector syringe needle.
Background technology
At present, the clinical nurse to serve at a hospital, because of the particularity of work, many occupational hazards are often faced with, wherein
Pricking wound is most commonly seen one kind.This is relevant with the syringe that has to contact in work, the sharp instrument such as puncture needle, once acupuncture
Wound can cause serious consequence, cause the psychological burden that nursing staff is lasting.Therefore, pricking wound and its harm are that our clinics are protected
The occupational exposure that scholar is faced with sternness is dangerous, and everybody should pay attention to the harm to pricking wound, strengthens the self-protection consciousness of nurse
And infection management, specific safeguard procedures are worked out, reduce or prevent the generation of nurse's pricking wound.
In the prior art, after medical personnel are using complete syringe, it is necessary to sheath is recovered into syringe needle again, prevent that other people from being pierced
Wound, but during set is returned, medical personnel are very likely wounded by stabbing.The patent of Patent No. 201420052159.3 discloses one
The medical needle of kind Anti-stabbing, the syringe needle need not return set, and the pintle length of the syringe needle needs the length more than syringe needle, for use in
Installation envelope needle cannula, does not apply to conventional syringe needle.
Utility model content
The purpose of this utility model is that providing a kind of need not return covers needling prevention injector syringe needle, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：It is a kind of to return set needling prevention injector pin
Head, including sheath, needle tubing, pintle, envelope needle cannula, elastic rubber plug, flank and needle stand, the needle tubing is connected with pintle, described
Pintle is threadedly coupled close to one end of needle tubing with sheath, and the other end is provided with needle stand；The pintle is cased with sealing needle cannula, the envelope pin
The both sides of sleeve pipe are respectively equipped with flank, and the elastic rubber plug is fixedly connected through pintle with envelope needle cannula one end, described envelope
Needle cannula and elastic rubber plug are with pintle to be flexibly connected.
Further, described envelope needle cannula is rubber hose.
Further, described flank is to be symmetrical arranged.
Further, the length of described elastic rubber plug is identical with the length on needle tubing inclined-plane.
Further, the aperture of described elastic rubber plug is less than needle tubing diameter.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, easy to use, makes
Whole needle slope part is sealed with elastic rubber plug, needle-stick injury and blood will not be also caused even if the apparatus without processing sharp instrument
The generation of source sexuality dye event.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
A kind of need not return as shown in Figure 1 and Figure 2 covers needling prevention injector syringe needle, including sheath (1), needle tubing (2), pintle
(3), seal needle cannula (5), elastic rubber plug (6), flank (7) and needle stand (8), needle tubing (2) to be connected with pintle (3), pintle (3) leans on
One end of nearly needle tubing (2) is connected with sheath (1) screw thread (4), and the other end is provided with needle stand (8)；Pintle (3) covers promising rubber hose
Needle cannula (5) is sealed, the both sides of envelope needle cannula (5) are arranged with flank (7), and elastic rubber plug (6) is through pintle (3) with sealing needle guard
Pipe (5) one end is fixedly connected.The length of elastic rubber plug (6) is identical with the length on needle tubing (2) inclined-plane.Elastic rubber plug (6)
Aperture is less than needle tubing (2) diameter, and it is to be flexibly connected to seal needle cannula (5) and elastic rubber plug (6) with pintle (3).
Before injection：Pull out sheath:(1) operator, can be by rotating flank (7) band according to operation needs before sheath (1) is pulled out
Dynamic pintle (3) is rotated to select the direction of pinpoint inclined plane, as nurse needed in aspiration medicinal liquid by pinpoint inclined plane rotate downwards with
Just decoction is suctioned out；Because operation needs, pinpoint inclined plane need to be rotated when subcutaneous or intradermal is injected and be upwardly into syringe graduation face.
(2) when pulling out sheath (1), fixed flank (7) place, the other hand are exerted oneself in being rotated by sheath (1) and pintle (3) screw thread (4) on the other hand
