Description

[0001] The present invention relates to a needle injection unit having a stick-

The present invention relates to a sticking needle and a liquid injection needle unit having an anti-infection function.

In general, to maintain / supplement the fluid, electrolytes, vitamins, proteins, fats and calories and the like, to properly maintain the blood constituents, or to promptly administer the drug in an emergency, In order to supply the patient, the patient injects liquid or drug into the vein of the patient through a syringe or the like.

In order to inject liquid or drug into the vein of the patient through the liquid injector, first, the blood vessel injecting needle film is injected into the blood vessel of the patient, and then the liquid connecting tube is connected to the hose connector of the needle film.

1A shows a front view of a conventional liquid injection needle unit 1 for injecting a needle film 20 into a blood vessel of a patient. 1B shows a front view of a conventional liquid injection needle unit 1 in a state in which the cover 10 is detached. 1C shows a state diagram schematically showing a state in which only the needle film 20 is detached and the liquid injection needle unit 1 is injected into the patient. 1D shows a front view of the conventional liquid injection needle unit 1 in a state in which the needle film 20 is detached.

As shown in FIG. 1A, the conventional liquid injection needle unit 1 includes a cover 10, a needle film 20, a needle 31, a body unit 40, and the like. The cover 10 is mounted on the upper end of the body unit 40 before the needle film 20 is injected.

1B, the cover 10 is detached to scan the needle film 20, and the needle 31 and the needle film 20 are inserted into the blood vessel of the patient, as shown in Fig. 1C. As shown in FIG. It can be seen that only the needle film 20 is left in the blood vessel and the liquid injection needle 1 is pulled out.

However, if the needle film 20 is detached from the conventional liquid injecting needle unit 1, there is a risk that the needle 31 is exposed to the outside and the sticking of the needle 31 is generated as shown in FIG. 1D . Therefore, there is a need for a method capable of preventing sticking of the needle film 20 originally before and after the injection.
