A tube for medical instruments according to the present invention includes: a tubular member that is made of resin, a linear member that includes a metal wire member and a resin coating film that covers the metal wire member and that surrounds the tubular member outside the tubular member, and a polymeric elastomer layer that is laminated on an outer circumferential surface of the tubular member such that the polymeric elastomer layer fills in at least a part of an outer peripheral portion of the linear member in a circumferential direction over a longitudinal direction of the linear member.

Provided herein is a device including a housing having a proximal end, a distal end, and a sidewall therebetween defining an interior, a fluid conduit displaceably received within the housing interior and having a proximal end and a distal end, the fluid conduit having a first conduit portion at the proximal end of the fluid conduit and a second conduit portion at the distal end of the fluid conduit, wherein the fluid conduit is configured to be advanced from a first, proximal position in which the second conduit portion does not extend beyond a distal end of a catheter of the intravenous catheter assembly to a second, distal position in which the second conduit portion extends beyond a distal end of a catheter of the intravenous catheter assembly, wherein at least a portion of the fluid conduit is configured to be antithrombogenic.

Herein is described a double or triple lumen, indwelling, urinary catheter having a bladder-protecting tip that has a drainage port centered at the end of the tips and a fitted check-valve. The catheter is useful for catheterizing patients whose bladders are in need thereof (e.g., due to a surgical procedure or other medical problem).

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

The present invention relates to a method of preparing reduced graphene oxide, incorporation of the reduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomeric articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of the reduced graphene oxide into polyisoprene latex is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.

A nasal cannula having sliding track mechanism, the nasal cannula has a flexible nasal prong body, the nasal prong body is combined with a rigid sliding track frame, an elastic portion of the nasal prong body is formed on the sliding track frame, an outside of the elastic portion is provided with a pair of nasal prongs; wherein two sides of the sliding track frame respectively have a track, a intake tube can be quickly combined to the nasal prong body in a sliding manner along a rigid track direction of the sliding track frame, and a gas tightness can be achieved between the nasal prong body and the intake tube, the intake tube can be quickly separated from the nasal prong body in a sliding manner along a track direction of the sliding track frame.

Provided are surface-modified rubbers or surface-modified thermoplastic elastomers, such as catheters, syringe barrels, tubes of medical instruments, and mudguard fenders, and methods for modifying the surface of rubber or a thermoplastic elastomer, wherein a lubricant layer is firmly bonded to the surface of medical devices such as catheters, syringe barrels, and tubes of medical instruments to impart lubricity to the surface and, further, improve the durability of the lubricant layer on the surface, thereby suppressing deterioration of the sliding properties. Included is a surface-modified rubber or a surface-modified thermoplastic elastomer each having a surface at least partially treated by polymerization of a monomer in the presence of a thermal polymerization initiator.

The present Invention' relates to a method of preparing reduced grapheme oxide, Incorporation of the adduced graphene oxide into polyisoprene latex to provide a polyisoprene latex graphene composite and elastomerk articles prepared using the polyisoprene latex-graphene composite. In particular, the reduction of-graphene oxide is accomplished without the use of strong reducing agents and organic solvents and incorporation of die reduced graphene oxide into polyisoprene latex Is accomplished using room temperature latex mixing method or hot maturation. The resultant composite exhibits good colloid stability and polyisoprene latex films produced from the composite exhibit good mechanical properties with improved ageing resistance.

The invention is directed to an ion plasma deposition (IPD) method adapted to coat polymer surfaces with highly adherent antimicrobial films. A controlled ion plasma deposition (IPD) process is used to coat a metal or polymer with a selected metal/metal oxide. Exposing the coated surface to ultraviolet light significantly improves the antimicrobial properties of the deposited coatings.
