Abstract

The utility model discloses a kind of insulin injection pen syringe needle puncture prevention needle cap, including cap body, the cap body tail end is provided with flat hand-held part, and the hand-held part is connect by rubber bellows with cap body tail end.The needle cap of the structure effectively prevents operator and is wounded by stabbing during returning set needle cap with syringe needle.

Description

Insulin injection pen syringe needle puncture prevention needle cap

Technical field

The utility model relates to medical instruments fields, and in particular to a kind of insulin injection pen syringe needle puncture prevention needle cap.

Background technique

Many patients need using insulin in clinic, and the frequency used is higher, generally needs to inject 3-4 times daily, Insulin injection is needed using insulin B D needle, although external advanced country is all to administer one injection to change a syringe needle, due to me State's national conditions, the insulin B D needle of patient will generally use 3-5 days.

It is in this way to need to return trocar head with needle cap after patient completes injection in medical staff, although requiring me on nursing book To return trocar head be all one-handed performance, it is not possible to be both hands operation, in order to avoid by stabbing, but since existing insulin B D is injected The distance of syringe needle and needle cap is very short, the insulin B D needle that China uses must be both hands operate back set needle cap could be by needle cap It fastens on syringe needle, therefore frequently results in the case where operator is stabbed by syringe needle during returning trocar head.

Accordingly, it is desirable to provide a kind of needle cap to match with existing insulin B D injection pen syringe needle, to effectively prevent When returning set needle cap with syringe needle, operator is wounded by stabbing.

Utility model content

In view of this, the purpose of the utility model is to provide a kind of insulin injection pen syringe needle puncture prevention needle caps, to have Effect prevents operator to be wounded by stabbing during returning set needle cap with syringe needle.

The utility model is solved the above problems by following technological means: a kind of insulin injection pen syringe needle puncture prevention needle Cap, including cap body, the cap body tail end are provided with flat hand-held part, and the hand-held part passes through rubber bellows and cap body tail End connection.

Further, the cap body tail end is provided with card slot, and the rubber bellows are provided with and block far from hand-held part one end The protrusion of slot clamping.

Further, the cap body front end is provided with the guide housing of cone cell.

Further, the hand-held part surface is provided with air bag layer.

The utility model has the beneficial effects that the insulin injection pen syringe needle puncture prevention needle cap of the utility model, including cap body, The cap body tail end is provided with flat hand-held part, and the hand-held part is connect by rubber bellows with cap body tail end.The knot The needle cap of structure effectively prevents operator and is wounded by stabbing during returning set needle cap with syringe needle.

Detailed description of the invention

The utility model is further described with reference to the accompanying drawings and examples.

Fig. 1 is the schematic diagram of the utility model.

Specific embodiment

The utility model is described in detail below with reference to attached drawing, as shown in Figure 1: the injection of insulin of the present embodiment Syringe needle puncture prevention needle cap, including cap body 1, the cap body tail end are provided with flat hand-held part 2, and the hand-held part passes through rubber Glue bellows 3 is connect with cap body tail end.In use, holding hand-held part, syringe needle returns set from cap body front end, during returning set, one Aspect, rubber bellows increase hand with a distance from syringe needle, hand can be effectively prevent to be wounded by stabbing, meanwhile, rubber corrugated pipe outer wall has Multi-ring annular slot also has barrier effect to syringe needle, further avoids hand and be wounded by stabbing even if operation error syringe needle thorn comes； On the other hand, the adjustable angle of rubber bellows makes hand-held part and cap body be not at same axis, and hand-held part is in cap body Certain angle when syringe needle returns set cap body, is conducive to that hand is avoided to be wounded by stabbing if hand-held part is vertical with cap body.

As further improvement to above-mentioned technical proposal, the cap body tail end is provided with card slot, the rubber bellows Hand-held part one end is provided with the protrusion 4 with card slot clamping.It thereby realizes rubber bellows and the detachable of cap body connects It connects, improves the convenience used.

As further improvement to above-mentioned technical proposal, the cap body front end is provided with the guide housing 5 of cone cell.One side Face, guide sleeve, which returns set needle cap to syringe needle, has guiding role, and on the other hand, when time set deviates, guide sleeve has resistance to syringe needle Gear effect, avoids the hand of needlestick injuries operator.

As further improvement to above-mentioned technical proposal, the hand-held part surface is provided with air bag layer 6.Set is returned in syringe needle In the process, hand-held part is held, there is squeezing action to air bag layer, therefore the utricule of expansion, utricule pair can be formed in finger front end Syringe needle has barrier effect, further avoids hand and is wounded by stabbing.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
