Tunnel Dressing For Use With Negative Pressure Wound Therapy System

US Patent:
2013003, Feb 7, 2013
Filed:
Oct 9, 2012
Appl. No.:
13/647756
Inventors:
Kevin P. Klocek - Wynnewood PA, US
John Karpowicz - Chester Springs PA, US
Assignee:
BOEHRINGER TECHNOLOGIES, L.P. - Phoenixville PA
International Classification:
A61M 1/00
US Classification:
604319
Abstract:
A tunnel dressing for use in treating a tunneling wound using negative pressure wound therapy. The tunnel dressing includes an elongate permeable member having a closed distal end for entering the wound and an open proximal end into which an applicator is removably disposed for guiding the dressing into the wound. The tunnel dressing has a support structure adapted to transport wound exudates away from the wound and to resist compression under suction. The tunnel dressing also has a wound contact surface adapted to minimize tissue entanglement to facilitate removal. The support structure and wound contact surface may be formed from the same material or from two adjacent layers of different material.

Device For Treating A Wound

US Patent:
7815616, Oct 19, 2010
Filed:
Sep 16, 2003
Appl. No.:
10/663226
Inventors:
John R. Boehringer - Wynnewood PA, US
John Karpowicz - Chester Springs PA, US
Christopher L. Radl - Malvern PA, US
Assignee:
Boehringer Technologies, L.P. - Phoenixville PA
International Classification:
A61M 1/00
US Classification:
604313, 604304, 604305, 602 41
Abstract:
A medical device is provided that encloses a wound and promotes wound drainage by suction. The device includes an enclosure to be placed over a wound, adhesively connected to the skin around the wound by a flange. Gauze type packing cylinders can be placed in the wound, and suction is provided either by a bulb type pump, or by a pair of regulators. When regulators are used, one alternates the suction that it provides, and the other is continuous, such that the level of suction is periodically varied. The suction facilitates the transfer of liquid from the wound to the packing cylinders and from the packing out of the enclosure. A leak detector is optionally provided.

Tube Attachment Device For Wound Treatment

US Patent:
2009013, May 21, 2009
Filed:
Dec 23, 2008
Appl. No.:
12/342238
Inventors:
John Karpowicz - Chester Springs PA, US
Christopher L. Radl - Malvern PA, US
Kevin P. Klocek - Wynnewood PA, US
John R. Boehringer - Wynnewood PA, US
Assignee:
BOEHRINGER TECHNOLOGIES, L.P. - Norristown PA
International Classification:
A61M 1/00
US Classification:
604313
Abstract:
The invention provides a vacuum tube attachment device for vacuum assisted wound dressings. The device is in the form of a patch that can be attached to the primary wound cover. The patch forms a substantially air-tight seal to the primary wound cover, and a vacuum tube is fixed to the patch such that the patch can be oriented on the wound cover to locate the tube near an opening in the cover to allow vacuum pressure to be communicated to the wound. The patch has an adhesive area around its perimeter for attaching the patch in a substantially air-tight seal to the wound cover at any convenient location on the cover. Several embodiments of the patch are described.
