ANTIBACTERIAL MEMBER

An antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration is provided. The antibacterial member includes a DLC film (F-DLC film) 40 containing fluorine at least partially or entirely on an outermost surface of a base material 10. The F-DLC film has an element ratio (F/(F+C)) of 17% to 72% and a nanoindentation hardness of 2,000 MPa to 16,000 MPa. This maintains wear resistance and close contact, and obtains an antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration. The F-DLC film does not necessarily need to cover the entire outermost surface of the base material but may be disposed in a mottled pattern.

Controlled release iodine structure for use with wound care

Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.

Traumatic wound dressing system with conformal cover

A wound dressing system that includes a conformal cover and an infusion pump is provided. The cover includes a fluid port and an oxygen catalyst. The infusion pump is configured to deliver a bioactive liquid to the cover via the fluid port. The liquid includes an oxygen precursor. Upon combination, the oxygen catalyst and precursor react to form oxygen. A method of applying a wound dressing system including a bioactive powder, a bioactive liquid, and a conformal cover to a wound site is also provided. The method includes applying the powder to the wound site; securing the cover around the wound site, where the cover includes an oxygen catalyst and a fluid port; and delivering the bioactive liquid to at least an inner layer of the cover via the fluid port, where the bioactive liquid includes an oxygen precursor.
