Abstract: A wiping tip (1) includes a hollow cylindrical member (10), and a cotton-like wiping member (20) arranged on the cylindrical member (10). The cotton-like wiping member (20) constitutes a thin film portion (21) covering an opening at an end of the cylindrical member (10), and an outer circumferential portion (23) extending from the thin film portion (21) and covering an outer circumferential face of the cylindrical member (10) over a predetermined length from the end.

Abstract: A male connector (1) includes a luer portion (10) connected to the upstream end of a tube (8) used in enteral feeding, and a lock portion (20) that is removably attached to the luer portion. The luer portion (10) includes a tubular male luer (11) in which a channel (17) in communication with the tube (8) is formed. The lock portion (20) has a hollow tubular shape and is open at two ends, and includes female threading (21) that opposes the male luer on the inner circumferential face of the lock portion (20). The male luer (11) is inserted into the lock portion (20). Rotation prevention mechanisms (16, 26) that engage with one another are provided on the luer portion (10) and the lock portion (20) such that the lock portion (20) does not rotate relative to the luer portion (10).

Abstract: The male connector (1) includes a connector body (10) and a lock nut (50). The connector body (10) includes a male luer (11), first female threading (41) that surrounds the male luer (11), a base end portion (20) that is inserted into a tube (8), a fixed protrusion (21) formed on the base end portion (20), and a spiral protrusion (32) between the male luer (11) and the base end portion (20). The lock nut (50) includes second female threading (52) that is screwed together with the spiral protrusion (32). When the spiral protrusion (32) and the second female threading (52) are screwed together, the base end portion (20) and the lock nut (50) clamp the tube (8). First rotation prevention mechanisms (14, 54) that engage with one another are provided on the connector body (10) and the lock nut (50) such that the lock nut (50) does not rotate relative to the connector body (10) when the tube (8) is clamped.

Abstract: A female connector (1) includes a female member (10). An inner circumferential face of the female member (1) includes a first region (11), and a second region (12) that is arranged on a tip side of the first region (11). The first region (11) is composed of a female tapered face whose inner diameter increases toward the tip of the female member. The second region (12) is composed of a cylindrical face whose inner diameter is constant along a central axis direction.

Abstract: A female connector (1) is connectable to a male connector (100) including a cylindrical male member (921). The female connector (1) includes: a tubular portion (11) having a hollow circular cylindrical shape to which the male member (921) is insertable; and a cylindrical portion (17) having a hollow circular cylindrical shape that is coaxial with the tubular portion (11) and surrounded by the tubular portion (11). When the male member (921) is inserted into the tubular portion (11), a liquid-tight seal (19) is formed between the cylindrical portion (17) and the male member (921), and the cylindrical portion (17) and the male member (921) communicate with each other.

Abstract: A tube end (14) of a barrel (12) of an injector (1) includes a tubular portion (921) on which a spiral projection (925) is formed, and an inner circumferential surface of the tubular portion is a female tapered surface (922). A small-diameter portion (16) is formed between a liquid storing portion (15) into which a plunger (18) is inserted and the tubular portion (921). A base end (21) of a liquid collection needle (20) is fluid-tightly connected to the small-diameter portion (16), and a leading end of the liquid collection needle (20) protrudes from the tube end (14).

Abstract: The medical liquid collection tip (1) includes a male member (11) that is to be inserted into a tube end (154) of an injector (150) at one end, and includes a liquid collection needle (20) at the other end. A flow path (8) penetrates through the tip (1) in a lengthwise direction thereof and causes the male member (11) and the liquid collection needle (20) to be in communication. The outer circumferential surface (12) of the male member (11) is a male tapered surface with an outer diameter that becomes smaller as the leading end is approached, and is configured to be fluid-tightly connected to the female tapered surface of the tube end (154).

Abstract: The male connector (1) includes a connector body (10) and a lock nut (50). The connector body (10) includes a male luer (11), first female threading (41) that surrounds the male luer (11), a base end portion (20) that is inserted into a tube (8), a fixed protrusion (21) formed on the base end portion (20), and a spiral protrusion (32) between the male luer (11) and the base end portion (20). The lock nut (50) includes second female threading (52) that is screwed together with the spiral protrusion (32). When the spiral protrusion (32) and the second female threading (52) are screwed together, the base end portion (20) and the lock nut (50) clamp the tube (8). First rotation prevention mechanisms (14, 54) that engage with one another are provided on the connector body (10) and the lock nut (50) such that the lock nut (50) does not rotate relative to the connector body (10) when the tube (8) is clamped.

Abstract: A double male connector (1) includes a first male luer (10) on one end and a second male luer (20) on the other end. The first male luer (10) and the second male luer (20) are in communication with each other. An outer circumferential surface of the first male luer (10) constitutes a first tapered surface (12) whose outer diameter decreases toward a leading end of the first male luer, and an outer circumferential surface of the second male luer (20) constitutes a second tapered surface (22) whose outer diameter decreases toward a leading end of the second male luer. A tubular portion (15) surrounds the first male luer (10). A female screw (16) is formed on an inner circumferential surface of the tubular portion (15).
