The subatmospheric pressure mechanism includes a housing having a control unit, a collection canister, and means for releasably connecting the housing and the canister. The collection canister collects exudates from the wound bed which has been removed under subatmospheric pressure supplied by the control unit. The connection means between the housing and the canister permits the removal of the canister for emptying thereof or replacement with a new collection canister. | 09-24-2009 |
20090326487 | Apparatus for Enhancing Wound Healing - A wound therapy apparatus for enhancing healing of a wound includes a wound dressing configured for placement over the wound to define a reservoir over the wound in which a wound contact fluid may be maintained by forming a substantially fluid-tight seal around the wound. An elastic bladder member defined by or within the wound dressing is expandable to exert a pressure on the wound contact fluid within the reservoir. A fluid system is in fluid communication with the reservoir for selectively delivering the wound contact fluid to the reservoir, and a pressure system is in fluid communication with the bladder member for delivering a compressed liquid or gas to the bladder member to effect expansion in the bladder member. | 12-31-2009 |
20100016815 | THIN FILM WOUND DRESSING - A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port. | 01-21-2010 |

Related articles are also described. | 03-04-2010 |
20100055158 | Environmentally Activated Compositions, Articles and Methods - An article includes a film layer; at least one layer of adhesive on at least one side of the film layer; a patch or strip comprising at least one antimicrobial agent, the patch or strip disposed on the same side of the film layer as the at least one layer of adhesive; and a relatively non-flexible sheet releasably attached to the side of the film layer opposite to the patch or strip. Alternatively, an article includes a film layer; a collagen layer; and a biodegradable hydrogel layer comprising PHMB; wherein the biodegradable hydrogel layer comprising PHMB is disposed between the film layer and the collagen layer | 03-04-2010 |
20100055437 | ANTI-MICROBIAL FIBERS AND RELATED ARTICLES AND METHODS - An antimicrobial fiber is described including: an inner layer and an outer layer; wherein the inner layer and the outer layer comprise at least one of the following characteristics: (I) the inner layer and the outer layer comprise of different concentrations, or different release rates, of at least one antimicrobial agent; and (II) the inner layer and the outer layer comprise different antimicrobial agents. An alternative antimicrobial fiber includes an antimicrobial agent compounded or combined with a dissolvable substance to promote release or binding of the antimicrobial agent. Related articles are also described. | 03-04-2010 |
