Abstract: The present disclosure provides medical implements having films fixed to at least a portion of their surface. In embodiments, a medical implement of the present disclosure may include a substrate including a synthetic resin, a film including a methyl vinyl ether-maleic anhydride copolymer in combination with a polyether block amide fixed to at least a portion of a surface of the substrate, and a silver ion bound to the film. Methods for forming such medical implements are also provided.

Abstract: A medical device that includes at least one antibiotic in a macromolecular substance that swells upon contact with a solvent. Also, a method for preparing an antibiotic-containing medical device that involves contacting a medical device having at least a portion of the surface formed from a swellable macromolecular substance, with a solvent that swells the macromolecular substance, contacting the swollen macromolecular substance with at least one antibiotic, and removing the solvent from the swollen macromolecular substance.

Abstract: A dialysis catheter is disclosed which comprises a catheter main body and a closure member. The catheter main body includes a first lumen which communicates with a tip-end hole and a second lumen which communicates with a side hole. The closure member has a shape in which a tip-end side of the closure member is inclined with a reduced diameter for closing off a tip-end opening. The side hole is a long hole extending in the catheter long-axis direction. The major axis of the side hole is at least 1.5 times the outer diameter of the catheter, and the minor axis is between 0.5 and 0.9 times the outer diameter. A base-end side of the closure member extends to the position of the side hole and seals the tip-end region thereof.

Abstract: The present invention relates to a fixing device (11) for fixing a tubular catheter (1) which is equipped with a plate-shaped fixing device body (21) and a fixed member (41). The plate-shaped fixing device body (21) possesses retaining parts (22) and a pair of wing pieces (23) that form a catheter retention slot (25). The fixed member (41) can be fitted onto the fixing device body (21) by being slid along the planar direction of the fixing device body (21). When the fixed member (41) is fitted, the retaining parts (22) are compressed by the fixed member (41), thus narrowing the catheter retention slot (25).

Abstract: A fluid flow detector includes a detector main body defining a fluid flow channel having a fluid flow detection channel positioned adjacent an upstream hole and a discharge channel positioned adjacent a downstream hole. A mobile body is positioned within the fluid flow channel and dimensioned to be movable along the fluid flow channel. The diameter of the fluid flow detection channel is smaller than the diameter of the discharge channel, and the maximum diameter of the outer peripheral edge part of the face of the fluid flow channel orthogonal to the direction of movement of the mobile body is slightly smaller than the diameter of the fluid flow detection channel. The upstream hole and the downstream hole are formed with a size and shape such that fluid can flow through the upstream and downstream holes without being obstructed by the mobile body.
