The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment is only for this utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in Figures 1 to 4, the totally-enclosed suction medicine of the present embodiment injection connector comprises injection tube adapter sleeve 1, described injection tube adapter sleeve is provided with shot sleeve link 2, syringe needle link 3 and medicine absorber link 4, between described shot sleeve link 2 and syringe needle link 3, be provided with injection canal 5, between described shot sleeve link 2 and medicine absorber link 4, be provided with and inhale medicine passage 6, in described injection tube adapter sleeve, be also provided with the reversal valve 7 for independent UNICOM's injection canal or suction medicine passage, described disposable totally-enclosed suction medicine injection connector also comprises medicine absorber, described medicine absorber is arranged on medicine absorber link 4, described medicine absorber comprises housing 9, in described housing 9, be provided with puncture needle 10, described puncture needle 10 is provided with medicine liquid channel 11, described medicine liquid channel 11 and suction medicine passage 6 UNICOMs, described reversal valve 7 is provided with separate passage I12 and passage II13, described passage I12 is used for connecting suction medicine passage 6, described passage II13 is used for connecting injection canal 5, described puncture needle 10 is arranged on the center of described housing 9 inner chambers, on described housing 9, be provided with elastic guide claw 14, on described elastic guide claw 14, be provided with guiding tapering 15, on described elastic card claw 14 inwalls, be provided with projection 16.
This example is by being arranged on the puncture needle 10 penetration of vials bottle stoppers 17 on housing 9, by the medicine liquid channel 11 on puncture needle 10, medicinal liquid is introduced to reversal valve 7, and the shot sleeve link 2 being arranged on injection tube adapter sleeve 1 is tightly connected with syringe 18, rotary reversing valve 7 will be inhaled medicine passage 6 by passage I11 and connect with injection canal 5, pushing syringe piston is by medicinal liquid inhalation syringe, whole adapter overturns, medicine bottle is inverted, more being conducive to medicinal liquid discharges, when needs are injected, rotary reversing valve 8 seals suction medicine passage 7 empty medicine is taken off, by passage II13, be communicated with injection canal 5 simultaneously, realize injection, whole suction medicine process is being carried out under sealing condition completely, avoided air pollution, guaranteed the quality of medicine.Owing to being provided with guiding tapering 15 at housing 9 oral areas, when medicine bottle enters housing 9, its guiding tapering 9 parts play the guiding role to bottle stopper, when bottle stopper oral area progresses into, the diameter that its tapering forms is also more and more less, ending place is less than bottle stopper diameter bottle stopper is held tightly, elastic card claw 14 is set and has better chucking power, protruding 16 structures are set, making to clamp effect can be better, due to the center of puncture needle 6, be arranged on the center of housing 5 inner chambers simultaneously, so when medicine bottle continues to enter housing 9 or puncture needle 10 and pierces through bottle stopper, puncture needle 10 is in medicine bottle center all the time, it is uniform making the stressed of process of needle pierces medicine bottle, can not produce partially askew, make whole operation simpler, and can not hurt hands refers to, improved safety.
The passage II13 of reversal valve can be that through type can be also side general formula, and this example is straight-through structure preferably, and Fig. 3 shows side formula.What deserves to be explained is at syringe needle link 3, be also provided with drainage screen, solve the de-problem such as cut of bulky grain object or rubber, can improve drug quality.
As the improvement to the present embodiment, the height of described puncture needle 10 is lower than the height of housing 9.Adopt this structure can protect medical personnel in the process of making up a prescription, to encounter because of carelessness while inhaling medicine dispenser, also can, by needlestick injury, further not improve safety.
As the improvement to the present embodiment, described medicine liquid channel will be lower than the height of medicine bottle stopper 17 inner surfacies at the height of puncture needle 10 porch.During due to suction medicine, medicine bottle is inverted, and the height outline of puncture needle 10 porch can drain medicinal liquid fully lower than the height of medicine bottle stopper 17 inner surfacies, guarantees dosage and therapeutic effect.
As the improvement to the present embodiment, on described housing 5, be provided with annular groove 19, described medicine absorber link is provided with the arc boss 20 adapting with annular groove.Syndeton between medicine absorber and injection tube adapter sleeve can be screw connection structure, can be also snap-in structure, can also be engaging screw thread combinative structure.This enforcement is preferably snap-in structure, is and is arranged on the annular groove 19 of medicine absorber link and is arranged on the arc boss 20 adapting with annular groove on lid.Adopt this structure to be easy to processing, simple in structure, and easy to use.
As the improvement to the present embodiment, on described housing 5, be provided with the connection plug with Rule tapering, on described reversal valve, be provided with and the close-fitting adapter sleeve of connection plug.During use, directly the adapter sleeve of reversal valve is inserted on the connection plug on housing, under action of gravity, can realizes and closely cooperating, medicinal liquid can not revealed, and this structure operation is succinct, easy to use.
As the improvement to the present embodiment, on described reversal valve 7, be provided with the interior hex-shaped recess for switch operation.Adopt this structure, can reduce the volume of whole device, and simple to operate.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although this utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
