Description

Two clips bottle pigment agent syringe

Technical field

This utility model relates to a kind of injector for medical purpose, specifically a kind of two clips bottle pigment agent syringe.

Background technology

Before day, the applicant had applied for a lot of syringes about pre-embedding class once in the application, all was basically to be made of pressurize an XiLin solvent bottle and a cassette solute bottle and the two intermediary conducting pin.Because pressurization cillin bottle technology difficulty in pre-embedding process is higher, so cause the whole cost of syringe higher.And these pressurization XiLin solvent bottle idols in processing or assembling process have error, then can cause gas leakage, do not have the purpose of automatic injection.In addition, if insufficient pressure in the solvent bottle of XiLin, solvent just can not all enter in the cassette solute bottle by the conducting pin, can cause liquid waste or administration deficiency.

Summary of the invention

The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, provides that a kind of difficulty of processing is lower, cost is lower, does not have the two clips bottle pigment agent syringe of gas leakage or insufficient pressure.

The technical solution that realizes above-mentioned purpose is: equidirectional cassette solvent bottle and the cassette solute bottle of being provided with in the syringe body, be provided with in the upper edge of solute bottle cut ring and with cut the screening glass that ring cooperates.

Its further technical solution is: the blade of cutting ring extend in the cannelure of screening glass.The company's of being interval with muscle in the cannelure of screening glass, the center of screening glass is provided with through hole.The internal diameter of cutting ring is slightly larger than the external diameter of solvent bottle.The edge of cutting ring is seated in solute bottle upper edge, and blade upwards stretches in the cannelure of screening glass.

By above technical scheme as can be seen, this utility model is owing to adopted cassette solvent bottle and the equidirectional setting on same axis of cassette solute bottle, and in two bottles atmospheric pressure state, push away handle promotion piston by I and II and the liquid vehicle in the solvent bottle can be pushed the mixed medicine of realization in the solute bottle by the conducting pin, can implement injection then.Substitute by cassette solvent bottle and to be filled with intrinsic pressure XiLin solvent bottle and can to reduce and produce and pre-embedding difficulty, and can not produce the phenomenon of gas leakage or insufficient pressure, solvent all can be advanced the solute bottle.In this syringe, be provided with in addition cut ring and screening glass more can guarantee every performance of syringe.

The specific embodiment

As shown in Figure 1, this syringe mainly be by syringe body 3, the cassette solute bottle 4 that is positioned at syringe body 3 and cassette solvent bottle 7, the support 6 that is positioned at solvent bottle 7 bottle mouth positions and conducting pin 19, screening glass 5, cut ring 15, one-level push rod 13, secondary push rod 12, push away handle 14, the DNA transduction 2 and the piston 16,17 that are positioned at solute bottle 4 bottle mouth positions constitute.Wherein, the conducting pin 19 and the support 6 of two ends band point and hollow are solidified as a whole, and the bottleneck outer wall of support 6 and solvent bottle 7 is for being slidingly matched.Place an annular in the upper edge of solute bottle 4 and had cutting of circular blade 24 and encircled 15 (referring to Fig. 4,5).The disc screening glass 5 (referring to Fig. 2,3) that centre is provided with through hole is placed on again to be cut above the ring 15, and this screening glass 5 is provided with cannelure 23, and bottom land has 2-4 company's muscle 22.Cut ring 15 blade 24 upwards and extend in the cannelure 23 of screening glass 5 (referring to Fig. 6).The internal diameter of cannelure 23 should be less than cutting ring 15 internal diameter in the said screening glass 5, and the internal diameter of cutting ring 15 should be slightly larger than the external diameter of solvent bottle 7.

Be equipped with a rubber piston 16 in the tail end of solute bottle 4, and be provided with a plug 20 in the front end bottleneck, be sliding combined with a DNA transduction 2 that is fixed with syringe needle 18 on the bottleneck outer wall.Syringe needle 18 on this DNA transduction 2 is not thrust plug 20 before implementing injection.Be with a needle guard 1 outside the syringe needle 18.

The tail end of solvent bottle 7 also is equipped with a rubber piston 17, also is provided with a plug 21 in the bottleneck of front end, is sliding combined with a support 6 on the bottleneck outer wall equally, but fixed on this support 6 be the tubular guidewire cleansing pin 19 of a two ends band point.Between solvent bottle 7 and syringe body 3, has a positioning sleeve 8.

The afterbody of syringe body 3 connects a retaining ring 11, be provided with a guide-localization ring 9 that is used to retrain one-level push rod 13 in the retaining ring 11 again, be with in the one-level push rod 13 one with push away the secondary push rod 12 that handle 14 fixes, also be provided with 2-4 outwardly directed claw 25 on this secondary push rod 12.The front portion of the adapter sleeve 10 of one-level push rod 13 lower ends is embedded in the piston 17.

As shown in Figure 7, when pushing away handle 14, I and II push rod 13,12 moves simultaneously, and drives 7 actions of solvent bottle by adapter sleeve 10 compressing pistons 17.When support 6 propped up screening glass 5, support 6 promptly slided backward.Conducting pin 19 pierced through the piston 16 of plug 21 and solute bottle 4 and makes two bottles to realize conducting when support 6 slid into range.Continuing to push away 14 of handles can make liquid vehicle realize mixing medicine in conducting pin 19 enters solute bottle 4.At this moment pull back again and push away handle 14, secondary push rod 12 is also pulled out in the lump, and this moment, claw 25 promptly was stuck in the end face (referring to Fig. 8) of one-level push rod 13.

Referring to Fig. 9, pull out needle guard 1 again and prepare to implement injection, press DNA transduction 2 and slide rearwardly to range, syringe needle 18 pierces through plug 20 simultaneously.

Referring to Figure 10; continue to push away handle 14 again; push against screening glass 5 and bearing external force owing to support 6 this moment; that is located in solute bottle 4 upper edges cuts the company muscle 22 of ring 15 blade 24 in can tripping protection sheet 5 cannelures 23; make screening glass 5 intermediary parts promote piston 16; whole medicinal liquids of mixing can be injected human body by syringe needle 18, finish shot operation.
