Abstract: In some embodiments, a negative pressure wound therapy device includes a negative pressure source and a controller configured to, in response to determining that the negative pressure source is directly fluidically connected to a wound dressing without a canister between the two, operate the negative pressure source in a first mode; otherwise, operate the negative pressure source in a second, different mode. The controller can be further configured to, in response to determining that a level of activity of the negative pressure source over a first time duration satisfies at least one of a leak or blockage condition, provide an indication of at least one of a leak or blockage and, in response to determining that the level of activity does not satisfy the at least one of the leak or blockage condition over a second time duration subsequent to the first time duration, discontinue providing the indication.

Abstract: A multi-layered wound dressing including a fibrous absorbent layer for absorbing exudate from a wound site. The wound dressing also includes a support layer configured to reduce shrinkage of at least a portion of the wound dressing.

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: Embodiments of negative pressure wound closure devices, systems and methods are disclosed. In some embodiments, a negative pressure apparatus includes a pump housing comprising a pump, a controller, and at least one light source and a panel removably attachable to the pump housing and configured to cover the at least one light source, the removable panel comprising one or more icons. The at least one light source can be configured to illuminate the one or more icons when the removable panel is attached to the pump housing.

Abstract: Negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some cases, the system can include a dressing having electronic circuitry that wirelessly communicates a dressing identifier and/or other dressing information to a controller of a pump assembly of the system. The controller can automatically modify one or more operational parameters of the pump assembly based on the dressing identifier and/or other dressing information wirelessly communicated. Duration of time over which the dressing has been in use can be monitored and provision of therapy by the pump assembly can be disabled responsive to a determination that the duration of time has reached operational lifetime of the dressing.
