摘要:
Antimicrobial compositions finding particular utility for coating access systems, lead devices including shunts, cannulae, catheters, catheter adapters, wires and other solid or hollow tubular devices used for a variety of medical purposes is provided. The composition comprises a material selected from the group consisting of acrylonitrile-butadiene-styrene copolymers, polyvinyl chloride, mixtures thereof, polyesters, polyurethanes, styrene-block copolymers, natural and synthetic rubbers, polycarbonates, nylon and silicone rubber mixed with an oligodynamic material consisting essentially of compounds of physiological, antimicrobial metals.
摘要:
Containers used for storing and dispensing liquids for medical applications include a closure, and medical connection device include cooperating connector members. An article of manufacture and a method are provided where a plastic outer closure is applied over container closures or over connection devices. The application of the plastic outer closure exerts an antibacterial effect in the juncture area defined by the interface of the outer closure and the container inner closure and neck, or defined by the interface of the outer closure and the connection site of the connector members. The outer closure is of a type of plastic that releases an antibacterial agent, which exerts an antibacterial effect in the juncture area.

摘要:
The coating of a RF active material on a non-RF active substrate material of typical thickness for packaging purposes, can generate sufficient thermal energy to effect strong bonding of the substrate materials. The RF active material may be deposited on less than the entire inner surface area of the substrate material, preferably, at or near the portion of the substrate surface which represents the heat seal interface. In this manner of application, additional coating or printing of other substances on the substrate surface can be achieved without hampering the heat sealing process. Flexible medical containers capable of containing a product which is maintained and removed under sterile conditions, can be constructed on commercial production machines from these coated non-RF active substrate materials.
