Condition, if nursing staff removes to remove the syringe needle on syringe with hand, there is also by the hidden danger of needlestick injuries, in the extreme danger.
Utility model content
The purpose of the utility model is to provide a kind of disposable syringe with safty pin head cap, the disposable note has been used
After emitter, the case where syringe needle being covered by the needle cap on syringe to avoid by needlestick injuries.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of band safty pin head cap
Disposable syringe, including syringe, syringe needle and the plunger in syringe, the pinhead sleeve is equipped with can be axial along syringe needle side wall
The needle cap of sliding is provided in the needle cap and is contradicted by syringe needle side wall and can cover needle tip in the reset state
Elastic parts.
By using above-mentioned technical proposal, when needle cap slides onto needle tip, the elastic parts in needle cap is lost
Syringe needle side wall resets its active force, and elastic parts can cover the tip of syringe needle after reset, and avoiding may be pierced by syringe needle
The hidden danger of wound.
Be further arranged to: the elastic parts is sheathed on syringe needle and is surrounded by a circle along syringe needle side wall.
By using above-mentioned technical proposal, elastic parts contradicts syringe needle side wall and encloses around for one, the elasticity group when resetting
Part loses syringe needle side wall and forms comprehensive protection effect to form the tip that sealing ring covers syringe needle to its active force
Fruit.
Be further arranged to: the elastic parts is additionally provided with a hook-type angle, and the hook-type angle can contradict the point of syringe needle
End.
By using above-mentioned technical proposal, hook-type angle can contradict the tip of syringe needle, can be by the hook-type before touching syringe needle
Angle is stopped, and is further avoided by the hidden danger of needlestick injuries.
Be further arranged to: force section is arranged in the barrel sidewall.
By using above-mentioned technical proposal, the hand of people is made to have a better force application location.
Be further arranged to: the force section extends to needle cap side wall.
By using above-mentioned technical proposal, the distance between needle cap and hand are reduced, by hand active force in force
Portion, one-hand operation realize the sliding of needle cap.
Be further arranged to: the barrel sidewall is provided with the locating part for limiting needle cap and syringe disengaging, described
Locating part wears with force section and connect.
By using above-mentioned technical proposal, when force section drives needle cap excessive slip, locating part plays barrier effect, prevents
Only needle cap and syringe are detached from.
In conclusion the utility model has the following beneficial effects: the elastic parts in needle cap loses syringe needle side wall pair
Its active force and while resetting, can cover the tip of syringe needle；Elastic parts is sheathed on syringe needle and is surrounded by a circle along syringe needle side wall,
Sealing ring and comprehensive conflict syringe needle can be formed when resetting；The hook-type angle being set on elastic parts simultaneously can contradict syringe needle
Tip can be stopped before hand touches syringe needle by the hook-type angle, and avoiding may be by the hidden danger of needlestick injuries；Barrel sidewall
It is provided with force section and the force section and extends to needle cap side wall, the hand of people is made to have a better force application location and facilitate list
Hand is operated；Barrel sidewall is provided with limiting section, and needle cap and syringe can be prevented to be detached from.
Detailed description of the invention
Fig. 1 is the perspective view of embodiment；
Fig. 2 is the structural schematic diagram of embodiment；
Fig. 3 is the portion A enlarged drawing in Fig. 2；
Fig. 4 is another structural schematic diagram of embodiment.
In figure: 1, syringe；2, plunger；3, syringe needle；4, needle cap；5, force section；6, locating part；9, elastic parts；9.1,
Support portion；9.2, bending section；9.3, hook-type angle.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
With reference to Fig. 1 and Fig. 2, a kind of disposable syringe with safty pin head cap, including syringe 1, syringe needle 3 and be located at syringe
Plunger 2 in 1, syringe needle 3, which is arranged with, to be provided with force section 5 along the needle cap 4 that 3 side wall of syringe needle axially slides, the side wall of syringe 1
And the force section 5 extends to 4 side wall of needle cap, which connect with needle cap 4 and needle cap 4 can be driven along 3 side wall of syringe needle
Realize axial sliding.1 side wall of syringe is provided with the locating part 6 for limiting needle cap 4 and the disengaging of syringe 1, locating part 6 and force
Portion 5 wears connection, which is located at the end face of syringe 1 and 3 junction of syringe needle and protrudes from the end face, the force section 5
For push rod.
When this syringe is in unused state, needle cap 4 be located at the end face of syringe 1 and 3 junction of syringe needle and with it is same
It is inconsistent that sample is located at the locating part 6 on the end face.
When this syringe is in using rear state, hand active force drives connected to it in force section 5, force section 5
Needle cap 4 carries out axial sliding along the direction at 3 side wall of syringe needle towards 3 tip of syringe needle.When force section 5 contradicts locating part 6, limited
The blocking of part 6 and can not continue to move to, needle cap 4 can just cover the tip of syringe needle 3 at this time.
With reference to Fig. 3, it is provided in needle cap 4 and is contradicted by 3 side wall of syringe needle and 3 tip of syringe needle can be covered in the reset state
Elastic parts 9, which is surrounded by a circle and will form sealing ring in the reset state along 3 side wall of syringe needle covers needle
First 3 tip.Elastic parts 9 includes support portion 9.1 and the bending section connecting with support portion 9.1 9.2, support portion 9.1 with
The inner sidewall of needle cap 4 contradicts, and bending section 9.2 is connected with hook-type angle 9.3 and the side wall of the hook-type angle 9.3 and syringe needle 3 contradicts simultaneously
Active force by 3 side wall of syringe needle is in deformed state.
With reference to Fig. 4, when the hook-type at needle cap 4 slides onto 3 tip of syringe needle and when covering 3 tip of syringe needle, on bending section 9.2
Angle 9.3 loses 3 side wall of syringe needle and resets to its active force.In the reset state, hook-type angle 9.3 is contradicting 3 tip of syringe needle
While can one sealing ring of formation snugly into each other, 3 tip of syringe needle is completely isolated in sealing ring, when hand touches syringe needle
Before 3, it can be stopped by the sealing ring, so as to avoid the hidden danger stabbed by syringe needle 3.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
