Description

Injection self-destructing safety needle Technical field

The invention relates to an injection self-destructing safety needle, in particular to a self-destructing combined device that can actively close the syringe liquid outlet after the liquid in the syringe is injected by a push cylinder, and has specific integrity. An irreversible injection self-destructing safety needle that actively combines self-destructive and detachable self-destructive effects. Ranch

Background technique

Generally, the conventional safety needle has a safety protection mechanism for preventing the safety needle from being reused by adding a sleeve on the outside or adding a mechanism to enable the push cylinder to be fixed in the syringe.

If the sleeve is used to prevent the safety needle from being used again, because it does not have irreversibility, it may be easy for some unscrupulous manufacturers to return to the concern of remanufacturing and resale after recycling, and the user is troubled by the combination of complexity.

It is also not self-destructive. The safety protection mechanism is not activated after injection by the user. The sleeve can be used repeatedly after being fixed on the syringe or fixed on the syringe. This is a major concern of the general safety needle. .

And if a mechanism is added to fix the push cylinder in the syringe, most of them will use the fixing device or squeeze the soft sleeve again to allow the hook to be combined with the push cylinder to fix it in the syringe, but it must be confirmed again. When the user pushes the pusher out again, most of them will detach the hook or the fixed device. Even the software or integrated type of the hook device is more likely to be detached and damaged or cause excessive residual liquid. It will enable unscrupulous manufacturers or users to easily pull out by force to make the safety needle remanufactured, resold or reused, and even the user can not press the soft sleeve again to allow the hook to combine with the push cylinder. After repeated use, the specific and complete self-destructive effect cannot be achieved.

Therefore, when the above safety needles are in use, the following problems and deficiencies really need to be improved:

First, the sleeve does not have real-time self-destructiveness, and is reversible, which cannot prevent remanufacture, resale, and reuse.

Second, the sleeve has a passive form, which cannot self-destruct after injection to force the user to activate the safety protection mechanism.

3. After the needle is injected, it is not self-destructive, which can cause repeated use without changing the needle.

Fourth, the self-destructive effect of safety needles is still difficult to achieve an effective and complete integrity to prevent the effect.

Therefore, how to solve the above-mentioned conventional problems and shortcomings is the direction that the applicants of the present invention and related manufacturers engaged in this industry are eager to study and improve.

Therefore, the inventor of the present invention, in view of the above-mentioned shortcomings, collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trials and modifications, he finally designed this type of injection when completed. After that, the liquid outlet of the syringe can be directly sealed to achieve the effect of active self-destruction, and it cannot be taken out to cause an irreversible effective specific and complete effect, so as to prevent others from remanufacturing, reselling, and reusing the self-destructing injection safety needle.

Please refer to FIG. 1 and FIG. 2, which are exploded views and cross-sectional views of the first preferred embodiment of the present invention. It can be clearly seen from the figure that the present invention includes:

An injection needle 1, a push tube sealing soft sleeve 2, a syringe opening 111, a syringe coupling portion 112, a syringe liquid outlet 113, a pushing piston portion 121, a pushing barrel combination 122, A combined body joint portion 13, a self-destructive combination device 3, a self-destructive piston portion 31, and a self-destructive sealing member 311, wherein the injection needle 1 includes a syringe 11 and a telescopically disposed end of the syringe 11 The push cylinder 12, push cylinder combination 122 is disposed at one end of the push cylinder 12, and the push cylinder combination 122 is provided with a joint combination portion 13, the push cylinder piston portion 121 is provided on the push cylinder combination 122, and the push cylinder The sealing soft sleeve 2 is engaged with the push cylinder 12 via the push cylinder piston portion 121. A syringe opening 111 and a syringe liquid outlet 113 are formed at both ends of the syringe 11, and a syringe coupling portion 112 is provided on the syringe. 11 One end of the syringe outlet 113 is provided for combining the needle 7; a self-destructing combination device 3 is provided on the injection needle 1; a self-destructing piston portion 31 is provided on the self-destructing combination device 3 for engaging and self-destructing The sealing member 311 (but the combination method is not limited) and cooperates with the self-destructing combined device 3 to selectively close the syringe liquid outlet 113, and then cooperates with the self-destructing piston portion 31 to reach The better sealing effect and the function of preventing the self-destructive plugging element 311 from being damaged are not limited.

The self-destructing combination device 3 includes a self-destructing engaging component 32 and a self-destructing positioning component 33. In this embodiment, the self-destructing engaging component 32 is provided on the push cylinder 12 and the self-destructing positioning component 33 is provided on the syringe 11. But it is not restricted.

In addition, the self-destructive joint assembly 32 includes a self-destructive joint body 321 connected to the combined body joint 13, two self-destructive joint rod bodies 322 connected to the self-destructive joint body 321, and two self-destructive joint rod bodies 322 formed on the self-destructive joint rod body 322. A self-destructing engaging rod hook 323, a self-destructing shrinkage diversion guide gap portion 324 provided between the self-destructing engaging rod body 322, and a self-destructing engaging rod body 322 and the self-destructing connecting body 321 and located between A self-destructing elbow 325 at one side of the self-destructing contraction diversion gap section 324.

The self-destructive positioning assembly 33 includes an annular limiting portion 331 provided on the inner wall of the syringe 11 and a combined perforated portion 332 formed at the center of the annular limiting portion 331.

Based on the above description, the structure of the present invention can be understood, and according to the corresponding cooperation of this structure, the self-destructive combination device 3 can be used to cooperate with the self-destructive sealing member 311 to achieve the combined self-destructive effect, and prevent others from using it again. , And a detailed explanation will be described below.

Please refer to FIG. 1 to FIG. 6 at the same time, which are exploded views to removal diagrams of the first preferred embodiment of the present invention. When the above components are configured, it can be clearly seen from the figure that the user can push the cylinder 12 penetrates into the syringe 11 through the syringe opening 111, and pushes the medicinal solution from the syringe outlet 113 through the syringe seal soft sleeve 2, and completely passes the needle 7 coupled to the syringe coupling portion 112 The medicinal solution is injected into the human body, but the manner of coupling the syringe coupling portion 112 and the needle 7 is not limited.

When the medicinal solution is fully pushed into the human body, the self-destructing engaging rod body 322 in the self-destructing engaging component 32 will be retracted inwardly by using the self-destructing shrinkage diversion gap 324, thereby partially passing through the bonding in the self-destructing positioning component 33. The perforated part 332 is then used to self-destruct the elbow part 325 to cooperate with its own elastic force to spread outward, so that the self-destructed engaging lever hook 323 can be aligned with the annular limit part 331, and the self-destructed contraction is contracted. The diversion gap portion 324 allows the medicinal liquid between the self-destructing engaging rod hook 323 and the self-destructive sealing member 311 to be more completely and easily injected into the body to reduce its residual amount. 324 its type position is not limited.

When someone wants to take out the push cylinder 12 forcibly to use the syringe 11 again, since the connecting force of the combined body joint portion 13 and the self-destructing connecting body 321 is smaller than that of the self-destructing engaging rod hook 323 engaged with the annular limiting portion 331 Therefore, the combined body joint portion 13 must be separated from the self-destructing connecting body 321, and the self-destructing connecting body 321 and the combined body joint 13 can be combined by means of adhesion or engagement, which is not limited. In this way, When someone forcibly pulls the force and wants to use it again, the push cylinder 12 will only be taken out, while the self-destructing combination device 3 will still remain in the syringe 11 and continue to cooperate with the self-destructing sealing member 311 to close the syringe discharge. The mouth 113 cannot be removed, that is to say, an irreversible detachment from the self-destructive state will be generated, so the effect of permanent self-destructiveness of specific integrity can be achieved.
