    摘要: The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreated article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional —OH end groups and reacting the —OH ends with a conventional monomer or prepolymer of a film-forming polymer capable of reacting with —OH groups. Such reactions are exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The —OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure. The film can be applied to the surface of an article by any convenient means of coating the article with the reaction mixture in solvent, and allowing the solvent to evaporate.

    摘要: A device for applying a lock solution in a catheter or other access system comprises a syringe (302) having an expulsion arrangement (305, 311) for expelling the lock solution from the device, said expulsion arrangement including a plunger (305) arranged in a housing (304), further comprising a sterile connector (303) for connecting the syringe (302) to the catheter. The connector (303) is arranged to engage a tip (307) of the expulsion arrangement (305, 311) tightly when the syringe (302) is inserted in the connector (303). The connector (303) is arranged to prevent the tip (307) of the expulsion arrangement (305, 311) from entering the catheter. The tip (307) is frangible. A method of applying a lock solution in a catheter or other access system is also disclosed.
