The present invention relates to polymeric medical articles comprising combinations of triclosan and silver-containing compounds. It is based, at least in part, on the discovery that these agents act synergistically, thereby permitting the use of relatively low levels of both agents. While it had been previously found that triclosan can be particularly useful when used in conjunction with chlorhexidine, it has been further discovered that medical articles having suitable antimicrobial properties may be prepared, according to the present invention, which contain triclosan without chlorhexidine. Such medical articles offer the advantage of preventing or inhibiting infection while avoiding undesirable adverse reactions to chlorhexidine by individuals that may have sensitivity to chlorhexidine.

The invention discloses a disinfection sterilization medical ultrasonic coupling medium with the bactericidal function and used in the ultrasonic detection and treatment of skin and cavitary mucosa and a preparation method of the coupling medium, wherein, the ultrasonic coupling medium comprises propylene glycol, de-ionized water and one viscosity modifier of the hydroxy ethyl cellulose, carbomerand hydroxy propyl cellulose. The coupling medium further comprises a fungicide of 0.05 to 0.15 percent and the constituents of the fungicide are any one of polyhexamethylene biguanide, benzalkonium chloride, benzalkonium bromide, chlorhexidine acetate, trichlorobenzene phenoxy diphenyl ether and nanometer silver or any combination of the olyhexamethylene biguanide, the benzalkonium chloride, thebenzalkonium bromide, the chlorhexidine acetate, the trichlorobenzene phenoxy diphenyl etherand, and the nanometer silver; the preparation method used for preparing the ultrasonic coupling medium is as follows: dispersing the hydroxy ethyl cellulose in the propylene glycol, stirring and dispersing the hydroxy ethyl cellulose by adding enough water, heating to 75 to 80 DEG C, preserving the heat for 30 minutes to cool the hydroxy ethyl cellulose and the propylene glycol to 45 DEG C, adding the fungicide to stir and cool the fungicide, the hydroxy ethyl cellulose and the propylene glycol to obtain the filled coupling medium. Tests show that the products of the coupling medium have fast and long sterilization effect and meet the requirements of various related standards.

This invention provides a modified catheter / indwelling device biomaterial that provides both immediate, and long-term microbiocidal effects on otherwise antibiotic-resistant strains of microorganisms. The material, which exhibits good mechanical performance characteristics for medical devices, is composed of a hydrophobic polyurethane (PU), a hydrophilic polyethylene vinyl acetate (PEVA) as an option, a soluble silver salt and a sparsely-soluble silver salt. The hydrophobic polyurethane provides the good physical properties, the PEVA the hydrophilicity necessary to allow some water ingress into the catheter, the soluble silver salt for an immediate burst effect, and the sparsely-soluble silver salt for sustained-release over many months postimplantation. Alternatively, the sparsely soluble silver salt can be silver iodate and is combined with silver sulfadiazine. Chlorhexidine can also be included in the material.
