Abstract
The present invention provides a safety injector with an easily detachable push rod. An injection needle of the safety injector can be retracted in an injection syringe. Moreover, under the design that a plane formed by an annular raised part is not perpendicular to the axial line of the injection syringe (for example, t1>t2), the push rod 67 can be tilted when a user pulls the push rod group towards the back end of the injection syringe. Therefore, lateral force 70 is generated. The push rod is more difficult to disengage from the injection syringe because of a tilted piston seat. The user can apply force to separate the push rod and the piston seat so as to disassemble the push rod.
Description
Technical field
The invention relates to a kind of safe syringe, refer to a kind of safe syringe that is easy to the push rod dismounting especially.
Background technology
Safe syringe is ceaselessly having obvious improvement under the improvement, such as function such as afterwards to take in the injection tube quite complete inject with syringe needle.Under the environment that the idea of resource recovery is now day by day popularized, how syringe being done effective recovery is the emphasis of further creating only.
The present invention is easy to the safe syringe with push rod dismounting, after having injected, with push rod group that does not contact liquid medicine and skin and the injection tube that contacts liquid medicine and skin and syringe needle component from.The injection tube and the syringe needle group of the sick mattress of PI can be destroyed, and the push rod group then can be done recovery.
The present invention is easy to the safe syringe with the push rod dismounting, comprises three parts such as injection tube, syringe needle group, push rod group.Wherein the syringe needle group has the needle stand snap fastener, and push rod group front end is a piston seat, and the front end of piston seat is provided with a piston seat snap fastener, and the rear end of piston seat is provided with a piston seat combining mechanism, and the front end of push rod is provided with a push rod combining mechanism.
Summary of the invention
The object of the present invention is to provide a kind of safe syringe that is easy to the push rod dismounting, it can be after having injected, and the piston seat snap fastener can engage with the needle stand snap fastener, makes the push rod group combine it with the syringe needle group.And the push rod group is when outwards pulling out, and push rod is detachably breaking away from piston seat, and makes syringe needle group and piston seat still stay in injection tube, and push rod can break away from injection tube easily.
Its effect is drawn in injection tube inside with the syringe needle group on the one hand, will not contact the push rod and the injection tube that contacts liquid medicine and skin of liquid medicine and skin on the one hand, the syringe needle group, reach piston portion from.And the injection tube of PI pathogenic bacteria and syringe needle group destroyed, push rod then can be done recovery, reaches the purpose that resource reclaims, or does different processing with injection tube and syringe needle group, and push rod is done common garbage disposal.
A kind of safe syringe that is easy to the push rod dismounting of the present invention is characterized in that, comprising:
One syringe needle group, comprising the needle body and the needle stand of a hollow, and needle body one end is fixed on the needle stand, and the needle stand rear end has the needle stand snap fastener;
One injection tube, main body become a hollow circuit cylinder cylindrical shell, and the injection tube rear end comprises a Handheld Division in addition; And
One push rod group, the front end of push rod group is a piston seat, and the rear end is a push rod, wherein:
Piston seat is equipped with a piston outward, and the front end of piston seat is provided with a piston seat snap fastener, and the rear end of piston seat is provided with a piston seat combining mechanism;
The front end of push rod is provided with a push rod combining mechanism, and wherein push rod combining mechanism and piston seat combining mechanism form bonding state, makes push rod form with piston seat and combines;
Wherein the piston seat combining mechanism is a combined hole, and the push rod combining mechanism is a dop;
By above-mentioned mechanism, after the push rod group is pushed the syringe needle group to, the piston seat snap fastener can engage with the needle stand snap fastener, make the push rod group combine it with the syringe needle group, and after the push rod group outwards pulls out, push rod is detachably breaking away from piston seat, and makes syringe needle group and piston seat still stay in injection tube, and push rod can break away from injection tube.
Wherein the inwall of injection tube rear end is provided with first lobe, makes piston seat be difficult for breaking away from injection tube.
Wherein first lobe is an annular relief.
Wherein the formed plane of annular relief is not for to become vertical with the axis of injection tube.
The front end of first lobe of wherein being separated by is provided with second lobe, make that the push rod group is outwards pulled out after, piston seat can be positioned between first lobe and second lobe.
Description of drawings
For further specifying structure of the present invention and feature thereof, this is further described in detail to the present invention below in conjunction with accompanying drawing, wherein:
Fig. 1 is the profile of syringe before the present invention injects.
Fig. 2 is the syringe profile of the present invention when having injected.
Fig. 3 is the syringe profile of the present invention when retracting push rod.
Fig. 4 is the syringe profile that push rod of the present invention breaks away from piston set.
Fig. 5 is the profile of piston set of the present invention and syringe inwall lobe.
The specific embodiment
Please refer to Fig. 1 and be easy to structure safe syringe 10 embodiment of push rod dismounting about the present invention.The present invention mainly is divided into injection tube 20, syringe needle group 30 and push rod group 60 three parts.
One of emphasis of the present invention is that piston seat 62 includes a piston seat 62 rear ends one piston seat combining mechanism 64 is arranged, and is a combined hole 641 in the present embodiment; And push rod 67 front ends include a push rod combining mechanism 68, are a dop 681 in the present embodiment; Wherein before abandoning safe syringe 10, push rod combining mechanism 68 forms bonding state with piston seat combining mechanism 62, makes push rod 67 form with piston seat 62 and combines.
Please refer to Fig. 4, after push rod group 60 is pulled to injection tube 20 rear ends, but the user application of force push rod 67 is separated with piston seat 62, so 67 of push rods can do to reclaim and reach the purpose that resource reclaims, perhaps push rod 67 is done common garbage disposal.
When push rod group 60 pulls to injection tube 20 rear ends, for avoiding push rod group 60 whole being drawn out outside the injection tube 20, usually general safe syringe is provided with first lobe 21, makes user way just to be arranged with push rod group 60 whole being drawn out outside the injection tube 20 with bigger strength.
Please refer to Fig. 5, first lobe 21 is that annular relief 211 is with known identical in the present embodiment, but annular relief 211 formed planes are not for becoming vertical (such as t1＞t2) with the axis 201 of injection tube 20, therefore when user pulls to injection tube 20 rear ends with push rod group 60, push rod 67 can tilt, thereby produce side force 70, add that piston seat 62 tilts to cause more being difficult to break away from injection tube 20.Therefore first lobe 21 of the present invention can more effectively be prevented throw-out lever group 60 whole being drawn out outside the injection tube 20.
The design of other second lobe 22 only is that piston seat 62 can be positioned between first lobe 21 and second lobe 22, and piston seat 62 more is difficult for being pushed to injection tube 20 front ends after breaking away from push rod 67.
To sum up institute is old, and no matter the present invention is all showing it totally different in the feature of known techniques with regard to purpose, means and effect, for the quantum jump that safe syringe is made, earnestly asks your juror to perceive, and grants quasi patent early, so that Jiahui society, the true feeling moral just.Only it should be noted that above-mentioned many embodiment give an example for convenience of explanation, the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
