Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1:
As shown in Figure 1, being made up of liquid medicine bottle and female Luer without silicone oil precharging type syringe in present embodiment, the bottle 2 of this liquid medicine bottle is band ripple extension type bottle, and bottleneck 1 is tightly connected with the cylindrical section 4 of female Luer, female Luer 5 connecting needle of female Luer.When injecting, at the bottom of the bottle of Manual press liquid medicine bottle 3, make liquid medicine flow out syringe arrival syringe needle through the aperture that bottleneck 1 is communicated with cylindrical section 4 inside by the liquid medicine in bottle 2 compression bottle and complete injection, residual in order to enable the liquid medicine in liquid medicine bottle not have as far as possible, at the bottom of bottle, 3 built-in protruding cylinders are to avoid liquid medicine residual condition.Fig. 2 is the structural representation of liquid medicine bottle and female Luer.
In addition, liquid medicine when leaving standstill to prevent syringe is because action of gravity flows out syringe automatically, dismountable capping 22 is set can also to this syringe, as shown in Figure 1, this capping 22 is provided with revolves tooth, corresponding, be provided with around female Luer 5 to revolve with this tooth with the use of screw cap 23, as shown in Figure 3, enter to screw cap 23 by tooth spiral will be revolved capping 22 is covered in female Luer 5 to avoid liquid medicine automatically to flow out.
Present embodiment compared with prior art, liquid medicine is promoted without the need to using rubber piston, and then avoid the silicone oil on rubber piston to pollute liquid medicine, and the liquid medicine bottle in present embodiment is except being convenient to the aperture of liquid medicine outflow in bottleneck 1, the whole Seal Design of remainder, also can avoid liquid medicine residual condition as much as possible when injecting like this.Be illustrated in figure 4 the view after liquid medicine bottle compression.
Embodiment 2:
Present embodiment is the further improvement of embodiment 1, main improvements are, conveniently inject, at the bottom of liquid medicine bottle bottle 3 be fixedly connected with push rod cut somebody's hair 8, as shown in Figure 5, also push seat 6 in liquid medicine bottle outer setting, liquid medicine bottle bottleneck 1 is positioned at and pushes seat 6 front opening (this opening can be designed to waist-shaped hole) place, and female Luer is fixedly connected with propelling movement seat 6 through pushing seat 6 front opening; In the present embodiment, female Luer and to push the connection of seat 6 be by arranging groove 19 on the cylindrical section 4 of female Luer, arranging and can the second draw-in groove 20 be fixedly connected be coordinated with above-mentioned groove 19 to realize pushing seat 6 front end, in a specific embodiment, also can be connected by alternate manner.Push action for convenience of implementation, symmetrical protrusion hooked hand 21 can also be set in the rear end pushing seat 6.
Embodiment 3:
Present embodiment is the further improvement on embodiment 2 basis, in present embodiment, main improvements are: after driving to prevent the push rod 7 of push rod 8 compacted medicament water bottles of cutting somebody's hair, liquid medicine is caused to reflux because liquid medicine bottle internal pressure becomes large bottle 2 situation of rebounding producing liquid medicine bottle, as Fig. 6, 7, 8, shown in 9, present embodiment is provided with multiple first serrate slot 9 on propelling movement seat 6 inwall, and cut somebody's hair edge arrange with the first serrate slot 9 with the use of the first draw-in groove 10, first draw-in groove 10 is also provided with positioning tooth 11, like this cut somebody's hair 8 propellings a bit after distance because positioning tooth 11 and the first serrate slot 9 engage, and then can prevent liquid medicine bottle resilience from causing liquid medicine to reflux and the generation of blood back phenomenon.Figure 10 is the view after syringe in present embodiment completes propelling movement.Annexation and the interaction of other parts in present embodiment are all identical with embodiment 2, do not repeat herein.
Embodiment 4:
Present embodiment is roughly the same with embodiment 3, main distinctive points is, as shown in FIG. 11 and 12, cutting somebody's hair of push rod is that the plunger type of damping and amortization cuts somebody's hair 12, this plunger type is cut somebody's hair and 12 is positioned at 3 rears at the bottom of the bottle pushing seat 6 inner liquid medicine bottle, with 3 be not be fixedly connected with at the bottom of bottle, this plunger type is cut somebody's hair and 12 3 effectively to be contacted with at the bottom of bottle in working order.When push rod 7 drive plunger type to cut somebody's hair at the bottom of 12 compression bottles 3 move forward to stop action after a segment distance time, the elasticity of self extending of liquid medicine bottle be not enough to overcome plunger type cut somebody's hair 12 with the frictional force pushing seat 6 inwall, doing so avoids the liquid medicine backflow because liquid medicine bottle resilience causes or blood back phenomenon.
It is worth mentioning that in addition, the plunger type in present embodiment is cut somebody's hair between 12 with push rod 7 and can be fixedly connected with by screw thread, and the alternate manner easily can certainly expected by those skilled in the art is connected.Figure 13 is syringe in present embodiment view when completing propelling movement
Embodiment 5:
Present embodiment is roughly the same with embodiment 4, main distinctive points is, as Figure 14, cut somebody's hair 8 is not that the plunger type of damping and amortization is cut somebody's hair, but common cutting somebody's hair, rebounded by the bottle 2 of liquid medicine bottle to prevent push rod, at push rod 7 outer wall, the second serrate slot 13 (as Figure 15) is set, correspondingly, extension component 14 (as Figure 16) is provided with in propelling movement seat 6 rear end, the inwall of this extension component 14 be provided with above-mentioned second serrate slot 13 with the use of elasticity locking tooth 15, in the process of push rod compacted medicament water bottle, namely in the process that push rod 7 advances, push rod resilience due to the bounce-back of the bottle 2 of liquid medicine bottle is prevented by the combined effect of above-mentioned second serrate slot 13 and elasticity locking tooth 15, so also can realize avoiding liquid medicine to reflux and produce the appearance of blood back phenomenon.Figure 17 is syringe in present embodiment view when completing propelling movement.
Embodiment 6:
Present embodiment is the further improvement on embodiment 5 basis, in present embodiment, as Figure 18, for the ease of removing and installing each parts, push seat to be designed to be fastened by fastener 18 by two symmetrical half cylindrical shells (16 and 17) form, on the front end that two parts of fastener 18 can be located at two and half cylindrical shells respectively and extension component 14, elasticity locking tooth 15 is located on extension component 14 inwall of one of them half cylindrical shell (16 or 17).
By reference to the accompanying drawings embodiments of the present invention are elaborated above, but the present invention is not limited in above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from present inventive concept.
