摘要： 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.

摘要： Provided is a medical puncture needle (10) capable of reliably administering a sufficient amount of a liquid medicine to a thin tissue. The medical puncture needle (10) includes: a main body (14) having a cylindrical shape and having inside a through hole (12); a blade surface (16) that has an annular shape and that is cut into a tapered shape so that a thickness of the main body (14) reduces toward a tip part (14a) of the main body (14); and a blade edge (18) that has an annular shape, the blade edge (18) being formed at a tip of the blade surface (16) so as to extend along a plane orthogonal to a central axis of the main body (14).

摘要： To provide a liquid medicine administration device capable of preventing leakage of a liquid medicine when blockage occurs in a liquid delivery path of the liquid medicine.
A liquid medicine administration device 100 includes: a liquid medicine container 110 having, at a tip, an opening through which the liquid medicine can be discharged; a gasket 135 for expelling the liquid medicine in the liquid medicine container, the gasket 135 being slidable on the inner wall of the liquid medicine container; a plunger 130 capable of pressing the gasket; a housing 120; a drive mechanism 140 that advances the plunger toward the tip of the liquid medicine container; and a rotation restriction unit 150 that restricts the rotation of the plunger with respect to the housing. The drive mechanism includes: a motor 141; a feed screw 142 that rotates in response to rotation of the motor; and a transmission unit 10 that transmits a drive torque from the motor to the feed screw. The transmission unit includes a canceling unit 20 that cancels the transmission of the drive torque from the motor to the feed screw, when receiving a torque equal to or greater than a preset cancellation torque from the motor.-

摘要： The present invention enables a user to drain a medicine that has been spilled when removing the air and is held in a skin contact portion. The invention is provided with a needle tube (5) having a needle tip for puncturing skin; a needle hub (6); and a fluid-draining portion (26) for enabling draining of the medicine. The needle hub (6) includes: a retention part (first member 11) for retaining the needle tube; an insertion part (31) into which the output portion (52) of a syringe is inserted; and a flange-like skin contact portion (25) that is disposed in a manner so as to cover a surrounding of the needle tube (5) and contacts with and/or faces the skin when a living body is punctured with the needle tube (5). Further, the fluid-draining portion (26) is disposed in the skin contact portion (25) of the needle hub (6).

摘要： The present invention is made 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 (2) having a needle tip capable of puncturing a living body, a hub (3) holding the needle tube, a stabilizer (4), and a guide portion (7). The stabilizer (4) is formed in a tubular shape surrounding the circumference of the needle tube (2), and an end face (6b) is pressed against the skin, and thereby a raised portion of the skin is formed in a tube hole (6a). The guide portion (7) is arranged on the stabilizer (4), and is adapted to recognize a press-in distance of the stabilizer (4) to the skin.
