Abstract: A needle does not come off even if a high back pressure occurs at the skin upper section. Thus, the drug leakage from the skin can be prevented. A drug administration device 1 includes a tubular section 2 having a fluid chamber 7 capable of accommodating a drug and a discharge section 22, a pusher member 3 moving within the tubular section 2, a grip section 4, and a connection section 5. The pusher member 3 includes a rod-shape plunger 31 and a gasket 32. The grip section 4 is disposed along the outer periphery of the tubular section 2 and kept away from the tubular section 2, and the connection section 5 is formed between the tubular section 2 and the grip section 4.

Abstract: A needle tip of a needle tube stuck in the skin is caused to be reliably positioned in the skin upper layer part and the injected drug is caused not to leak to the outside of the body. An injection needle is provided with a needle tube having a needle tip, a hub that holds the needle tube and an adjustment unit provided around the needle tube and having a needle-protruding surface through which the needle tip of the needle tube protrudes. The needle-protruding surface of the adjustment unit is formed such that the distance S from the circumferential edge to the circumferential surface of the needle tube is in the range of 0.3-1.4 mm.

Abstract: To securely position a needle tip and a blade face of a needle tube inserted into the skin in a predetermined site of a living body, such as the upper layer of skin, an injection needle assembly includes a needle tube having a needle tip capable of puncturing a living body, a hub holding the needle tube, a stabilizer, and a guide portion. The stabilizer is formed in a tubular shape surrounding the circumference of the needle tube, and an end face is pressed against the skin, and thereby a raised portion of the skin is formed in a tube hole. The guide portion is arranged on the stabilizer, and is adapted to recognize a press-in distance y of the stabilizer to the skin.

Abstract: An injection needle assembly includes a needle tube having a needle tip to be stuck into a skin, a first member, a second member, an adjustment portion, and a pressing force restricting member. The first member holds the needle tube and the second member holds the first member movably toward the axial direction of the needle tube. A discharge portion of the syringe is fitted into this second member. The adjustment portion is provided at the periphery of the needle tube and includes a needle protrusion surface which abuts the skin in a case in which the needle tube is stuck to the living body. The pressing force restricting member is arranged between the first member and the second member, and restricts the pressing force added from the first member to the skin.

Abstract: 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.
