Abstract: Systems and methods for sterilizing iodophor compositions are described. In some cases, the iodophor composition comprises a complex comprising iodine and a polymer (i.e., an iodine-polymer complex). The iodine-polymer complex may be polyvinylpyrrolidone iodine (also referred to as “povidone-iodine” or “PVP-I”) or iodine povacrylex. Methods are described for heating an initial iodophor composition to produce a sterilized iodophor composition. The resulting sterilized iodophor composition may have a relatively high assurance of sterility (e.g., a sterility assurance level of 10?3 or less, 10?6 or less). In some cases, heating the initial iodophor composition comprises exposing at least a portion of a container containing the initial iodophor composition to a heated liquid. In certain cases, the heated liquid is part of a moving liquid stream (e.g., a cascading waterfall stream produced by a cascading waterfall sterilizer).

Abstract: A slide clamp for use with an infusion pump and infusion set provides finger grips and support members for supporting the infusion tubing. The finger grips make the slide clamp easier to use while reducing the risk of error. The tubing support members reduce the likelihood of improperly loading the tubing and reduce the risk of kinking the tubing during use. An infusion set is provided wherein the slide clamp may be coded through the use of colors, holes, or the like so as to identify the type of infusion tubing used therewith. The infusion pump can identify the code on the slide clamp and thereby determine the type of infusion tubing, and thereby allow access only to infusion programs for drugs or infusion solutions which are compatible with the particular type of infusion tubing.
