Description

Anti-acupuncture syringe

Technical Field

The utility model relates to a prevent acupuncture syringe.

Background

The first modern glass syringe originated from the English french. The glass has good transparency, so that the condition of the injected medicine can be seen, and the glass is gradually popularized. The syringe made of glass tube metal can be used for sterilization by boiling, and the needle can be used for sharpening and sterilization. The development of the prior disposable syringe which is made of plastic can be realized, and the disposable syringe can be recovered and damaged after being used up, thereby greatly reducing the risk of infection during injection. Clinically, however, nurses have a very high frequency of using syringes, so various needle stick injuries inevitably occur, and the needles are most easily punctured when being pulled back, which increases the risk of occupational injuries, and if patients have certain infectious diseases, the injuries caused by the needle stick injuries are larger, which causes great injuries to clinical work.

In order to solve the problems, the utility model relates to a prevent acupuncture syringe.

SUMMERY OF THE UTILITY MODEL

The utility model discloses overcome the above-mentioned not enough that exists among the prior art, provide a prevent acupuncture syringe, help reducing occupational injury risk.

The utility model provides a technical scheme that its technical problem adopted is:

an anti-acupuncture syringe is characterized by comprising a needle cap, a needle head, a locking cover, a syringe main body, a rubber cap, a spring and a spring base; the top end of the spring is provided with the rubber cap; the top end of the rubber cap is provided with a through hole, and the through hole can be penetrated by a needle head; the bottom end of the spring is connected with the spring base; a syringe connecting sleeve is combined in the spring base and fixed at the front end of the syringe main body; the spring is arranged at the periphery of the needle head, can be stored in the spring base when being compressed, and has the length capable of enabling the rubber cap to protect the sharp top of the needle head after being popped out; the locking cover is in threaded connection with the outer peripheral wall of the spring base; compressing the spring within the spring seat.

On the basis of adopting above-mentioned technical scheme, the utility model discloses still can adopt following further technical scheme, or to these further technical scheme combined use:

the rubber cap is provided with a circle of brim and is connected with the spring through the brim.

The locking cover is provided with a top used for pressing the rubber cover, the top is in limit fit with the brim of the rubber cap, and when the locking cover is screwed tightly, the spring is compressed in the spring base under the action of the top on the brim of the cap.

The spring is a conical spring.

The spring base includes the periphery wall cylinder adapter sleeve and bottom, periphery wall, cylinder adapter sleeve and bottom make up into transversal V-arrangement or trapezoidal spring mounting groove of personally submitting.

The spring is connected with the spring base into a whole.

And the spring is wrapped with a PVC film.

The outer side of the upper part of the locking cover is provided with a circle of concave parts, and the needle cap is inserted into the concave parts and limited by the concave parts.

The utility model has the advantages that:

1. the needle head does not need to be sleeved back, so that the protection effect is good;

2. after the injection is finished, the spiral cap is rotated to be separated from the spring seat, so that the spring can be automatically ejected, the operation is convenient, and the clinical work is reduced;

3. the material is simple and the cost is low.

Fig. 2 is a schematic diagram of the state that the spring automatically pops out without returning the cover after the injection of the utility model is finished.

Fig. 3 is a sectional view of the front end structure of the present invention before injection when it is not used.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in the figure, the utility model provides a prevent acupuncture syringe, including needle cap 1, syringe needle 2, locking lid 3, cylinder main part 4, rubber cap 5, spring 6, PVC tectorial membrane 7, spring base 8.

The rubber cap 5 is settled on 6 tops of spring, rubber cap 5 can be connected with spring 6 through modes such as bonding or joint, rubber cap 5 is provided with round brim of a hat 52, is connected with spring 6 through brim of a

hat

52, and 5 tops of rubber cap set up through hole 51, and through hole 51 can supply syringe needle 2 to pass, PVC tectorial membrane 7 wraps up spring 6.

As shown in fig. 3, the spring 6 and the spring base 8 are integrally formed and fixed at the front end of the syringe body 4, the spring 6 is arranged at the periphery of the needle 2 and can be stored in the spring base 8 when being compressed, after being popped up, the length of the spring can ensure that the rubber cap 5 can protect the sharp top of the needle 2 to avoid puncture accidents, the syringe connecting sleeve 81 is combined inside the spring base 8, and the needle is fixed at the top of the syringe connecting sleeve 81.
