JPH06254163A - Slidable double structure injection needle cap integrated with injection needle - Google Patents

Abstract

PURPOSE:To prevent the troble of the contagion of the viruses, etc., of AIDS, B-type liver disease, etc., in the very dangerous action such as the application of a cap on an injection needle by a person who has bad eyes or has quavery hands, in the conventional case where the injector needle and the cap are prepared separately and the injector needle after use is discarded after applying the cap. CONSTITUTION:As for a cap for an injection needle which is formed integrally with the injection needle, an inside cap 2 is connected with an injection needle body 3, and the inside cap 2 possesses the function for the bending at the connection part and has a groove for the introduction of the injection needle 9 on the side part. As outside cap 1 is installed on the inside cap 2, and both caps 1 and 2 can be slided. The injection needle 9 is exposed by extending and bending the outside cap 1, and after use, the injection needle 9 is accommodated into the cap, passing though the groove on the inside cap 2, by returning the outside cap 1, and the injection needle 9 is fixed in the cap by contracting the outside cap 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a viral infectious disease such as AIDS and hepatitis B caused by a needle after use.
The purpose of this is to prevent transmission from accidents caused by doctors, nurses, and other medical staff.

[0002]

2. Description of the Related Art An injection needle and a cap are separate items, and the cap is removed before use. The current situation is that the cap is put back on and discarded after use. Moreover, since the needle tip is passed through the small hole in the cap mouth, there is a very high risk.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since the needle tip is passed through a small hole in the mouth of the injection needle cap, there is a risk that the user may be stabbed by the finger, hand, etc. when covering the injection needle after use with a person with poor eyesight or shaking of the hand. ing.

[0004]

[MEANS FOR SOLVING THE PROBLEMS] An inner cap is connected to a main body of an injection needle, and the inner cap has a function capable of being bent by a connecting portion and a groove for allowing the injection needle to be put in and out on a side. The outer cap is mounted on the inner cap, and the inner cap and the outer cap can slide. The needle is exposed by stretching and bending the outer cap, and after use, it will fit in the cap by passing through the groove of the inner cap, and by fixing the outer cap, the needle is fixed in the cap. Is a cap for an injection needle integrated with an injection needle.

[0005]

[Operation] When the cap integrated with the injection needle configured as described above is used to cover the injection needle after use, instead of inserting it into the cap from the needle tip, the groove of the inner cap is inserted from the side of the needle. Since it fits in the street cap, the risk of accidentally piercing the fingertip or the needle tip in the hand is reduced, and it can be easily handled by people with poor eyesight and by shaking hands.

EXAMPLES Examples will be described with reference to the drawings. Reference numeral 1 shown in FIG. 1 denotes an outer cap, and the inner cap is slid or bent while holding this portion.
Reference numeral 2 shown in FIG. 1 is an inner cap having a groove through which a needle can go in and out. Reference numeral 3 shown in FIG. 1 denotes a needle main body, which has a cap inside 2 and a foldable connecting portion. Reference numeral 4 shown in FIG. 1 is a syringe.

The concave portion 5 shown in FIG. 1 is for fixing the cap that accommodates the needle by the convex portion 7 of the inner cap. The concave portion 8 shown in the drawing is a stopper portion for preventing the outer cap portion 1 from being pulled out from the inner cap portion when the outer cap portion is stretched, and the convex portion portion 7 stops the outer and inner cap portions.

6 shown in FIG. 1 has two outer caps 1
When inserting the inner cap of the above, a notch is provided to pass through the recess of 8. Once part 7 of the inner cap is in the outer cap, it must not be removed during use.

Reference numeral 10 shown in FIG. 1 denotes a connecting portion between the injection needle main body and the inner cap of 2, which can be bent.

Reference numeral 11 shown in FIG. 3 is a groove formed on the flank of the cap into which 9 needles can be inserted and withdrawn. The needle goes in and out through the groove by bending or returning the cap.

(A), (B) and (C) shown in FIG. 4 show the use process. (A) is a state in which the injection needle is set in the cap. (B) is a state in which the outer cap is stretched to expose a groove through which the inner needle can go in and out. (C) is a state in which the cap is bent and the injection needle is exposed and is ready for use.

Regarding the material, the same material as the cap for the currently used injection needle may be used, and nylon, vinyl, synthetic resin, plastic, or any other material suitable for different injection needles is used.

The shape is not limited to the circular shape. Square, hexagon, octagon, etc. are free.

Regarding the size of the cap for the injection needle integrated with the injection needle, there are injection needles having different purposes of use, and the size of the cap is different depending on the syringe and the injection needle. The different injection needles are used for infusion, blood collection, and other purposes.

[0015]

Since the present invention is configured as described above, it has the following effects.

It is possible to safely and easily store a used injection needle in a cap even for those with poor eyesight and those with shaking hands.

Since the used needle rarely accidentally pricks a finger hand, the number of people who have a viral infectious disease is reduced.
