The cartridge bottle injection syringe has the advantages that the needle seat of the needle tube is connected with the connecting part of the injection frame in a sticking mode through an inner-outer thread or an outer-inner thread or through the method of embedding of a clamping groove, the center of the needle seat and the center of the connecting frame are provided with Ruhr taper connectors which are matched, so that a needle head does not swing and the injection process is safe.
Description
Technical field
This utility model relates to the clip type bottled syringe that a kind of injection liquid exempts to shift, and particularly clip type bottled syringe is exempted from transfer device.
Background technology
Traditional clinically injection operation is, break off with the fingers and thumb broken with hands earlier or break ampoule bottle, then with disposable syringe with the medicinal liquid sucking-off, implement the human injection again.Be easy to generate glass chip like this and sneak into medicinal liquid, can bring unnecessary injury to the patient, simultaneously, cause secondary pollution easily at the transfer process herb liquid, and contaminated environment.The various clip type bottled syringes that occur are the numerous and diverse suitability for industrialized production that is unfavorable for of structure then, and injection needle easily swings, and makes troubles for medical personnel's clinical manipulation.
At above deficiency, also released following several clip type bottled syringe of exempting to shift on the market, weak point is to use inconvenience, needs to spin off actions such as enclosing cover before using.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the clip type bottled syringe that provides a kind of injection liquid to exempt to shift, this structure syringe can carry out direct injection in order to avoid shift injection liquid, avoided the glass chip of ampoule bottle to sneak into the medicinal liquid patient harm, prevented that also the secondary pollution of medicinal liquid and medicinal liquid are to the pollution of clinical setting.The syringe needle of this kind syringe is fixed simultaneously, does not swing, and can make that injection is safer, and is reliable.
To achieve these goals, the technical solution of the utility model is:
The clip type bottled syringe that injection liquid exempts to shift, comprise tubulose injection frame, the injection frame is fixed cassette bottle close-fitting by spacing ring and injection frame connecting portion, and the cassette bottle is positioned at tubulose injection frame, described cassette bottle is equipped with aqueous injection or injectable powder in advance, cassette bottle two ends are respectively by plug and piston seal, core bar is rotatably connected on the piston by embedding engaging or screw thread, injection frame connecting portion engages by straight cutting with needle stand or is threaded, injection frame connecting portion center is provided with Rule tapering joint of standard, and Rule tapering that the needle stand inner chamber has standard cooperates with joint sealing; There is the cutting edge that is fit to the puncture plug at the two ends of needle tubing, and needle tubing is with sheath outward.
Injection frame connecting portion and needle stand are by being threaded to: injection frame connecting portion is provided with female thread, external screw thread or draw-in groove, and needle stand is provided with corresponding external screw thread, female thread or draw-in groove, and needle stand is connected with injection frame connecting portion.
Injection frame inwall is provided with spacing ring.
The end shape of piston and cassette bottle bottleneck shape match.
The beneficial effects of the utility model: the needle stand of bonding needle tubing and injection frame connecting portion are connected by internal and external threads or outer female thread or the chimeric mode of draw-in groove, and both centers are provided with Rule cone joint of coupling, make syringe needle not swing, and injection process is very safe.Piston tail end and the core bar of cassette bottle is to embed engage or be threaded, can be before use with core bar separately and the minimizing package length in order to deposit and transport.Another of piston section then has the shape that matches with cassette bottle bottleneck angle, to reduce the medicinal liquid residual quantity in the injection process.
