Abstract: Embodiments described herein relate to apparatuses, systems, and methods for the treatment of wounds, for example using multiple wound dressings in combination with negative pressure wound therapy. A negative pressure would therapy apparatus can include a negative pressure source and a controller. The negative pressure source can include inlets configured to couple via fluid flow paths to wound dressings. The fluid flow paths can include pressure sensors configured to measure pressure in the fluid flow paths. The pressure sensors can include a first pressure sensor configured to measure pressure in the first fluid flow path and a second pressure sensor configured to measure pressure in the second fluid flow path. The controller can be configured to operate the negative pressure source and provide, based on measured pressure, indication of at least one operating condition associated with at least one of the fluid flow paths.

Abstract: Disclosed herein are several embodiments of a wound treatment apparatus employing a wound dressing for negative pressure wound therapy and methods of using the same. Some embodiments are directed to improved wound dressing to be applied to a wound site, for example a wound dressing including a three-dimensional filter element, and methods of using the same.

Abstract: A negative pressure wound therapy apparatus can include a housing, a negative pressure source supported by the housing and configured to aspirate fluid from a wound covered by a wound dressing, a switch positioned on an exterior surface of the housing, and a controller configured to operate the negative pressure source. The controller can be configured to, responsive to receiving a first user input via the switch, operate the negative pressure source to aspirate fluid from the wound at a first fluid flow rate. The controller can be configured to, responsive to receiving a second user input via the switch subsequent to receiving the first user input, operate the negative pressure source to aspirate fluid from the wound at a second fluid flow rate greater than the first fluid flow rate.

Abstract: Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a wound dressing comprising an absorbent layer comprising a plurality of portions of absorbent material that can be physically separate from each other. In some embodiments, a wound treatment apparatus can include an absorbent layer comprising a compressed portion configured to impede the flow of fluid therethrough. In some embodiments, a wound treatment apparatus can include an absorbent layer and spacer layer positioned side by side.

Abstract: A negative pressure wound therapy system can include a negative pressure source configured to provide, via a fluid flow path, negative pressure to a wound covered by a wound dressing. The system can include a controller. The controller can be configured to periodically activate the negative pressure source to maintain negative pressure in the fluid flow path between a low negative pressure setpoint and a high negative pressure setpoint. The controller can be configured to determine a change in a volume of the wound based on a difference between a first time and a second time at which the high negative pressure setpoint has been established in the fluid flow path, the second time being subsequent to the first time. The controller can be configured to provide indication of the change in the volume of the wound.
