SYRINGE NEEDLE ASSEMBLY AND MEDICATION INJECTION DEVICE |
摘要 |
To prevent a coating agent applied to the surface of a needle tube from being infiltrated into the clearance between the needle tube and a needle hub, a device comprises a needle tube that has a needle tip capable of puncturing a living body and that is coated with a coating agent on the surface of a tip-end portion on the side of the needle tip; and a needle hub adapted to hold the needle tube in a state where the needle tip of the needle tube is protruded. The needle hub has a through-hole through which the needle tube is inserted, and a discharge hole extending from the through-hole to the outer surface of the needle hub and adapted to discharge the coating agent infiltrated into the through-hole. |
