1. A wound dressing for use in a vacuum wound therapy treatment comprising:
- a cover layer configured for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound;
a portal member mounted to the cover layer, the portal member defining a fluid passage for fluid coupling with a reduced pressure supply conduit for creating the reduced pressure within the reservoir; and
a filter screen integral to the portal member and mounted relative to the fluid passage, the filter screen dimensioned to minimize passage of tissue particles of predetermined dimension through the fluid passage of the portal member.

Abstract
The present disclosure describes a dressing for use in a vacuum wound therapy procedure to promote healing of a wound. The dressing includes a cover layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member is mounted relative to the cover layer and defines a fluid passage for fluid coupling with a reduced pressure supply conduit for creating the reduced pressure within the reservoir. A filter screen is mounted relative to the fluid passage and is dimensioned to minimize passage of tissue particles of predetermined dimension through the fluid passage of the portal member.

11. A wound dressing for use in a vacuum wound therapy treatment comprising:
-
a cover layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound; a portal member mounted to the cover layer, the portal member defining a fluid passage for fluid coupling with a reduced pressure supply conduit for creating the reduced pressure within the reservoir, the portal member including an opening adapted to receive a vacuum tube in a releasable and fluid tight manner; and a filter screen integral to the portal member and mounted such that a base of the filter screen extends across an entire face of the fluid passage, the filter screen including a plurality of distinct openings extending directly through the base in a direction of fluid flow through the portal member, the openings dimensioned to reduce passage of tissue particles of predetermined dimension through the fluid passage of the portal member wherein each of the distinct openings extending through the base of the filter screen exhibits a cross-sectional area smaller than a cross-sectional area of the opening adapted to receive the vacuum tube, the distinct openings collectively exhibiting a cross-sectional area greater than the cross-sectional area of the opening adapted to receive the vacuum tube. - View Dependent Claims (12)
