Abstract: Disclosed herein are systems and methods for safe operation of a wound treatment apparatus with electronic components integrated on or within a wound dressing. In some embodiments, the electronic components include a power source, an isolation circuit, a controller, a capacitor, and a negative pressure source. The isolation circuit provides multiple activation states with at least one state preventing application of power to the other electronic components capable of storing electrical energy, thereby providing a safe operation of the apparatus. For example, sterilization of the apparatus can be performed safely.

Abstract: Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound contact layer, an absorbent layer over the wound contact layer, the absorbent layer comprising one or more apertures, a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer, and an electronics assembly comprising a negative pressure source. A portion of the cover layer overlying the one or more apertures in the absorbent layer can be configured to be compressed within the aperture in the absorbent layer when negative pressure is applied to the wound dressing apparatus. The compressed cover layer can indicate a level of negative pressure below the cover layer. In some embodiments, the wound dressing apparatus can comprise an indicator material layer and a cover layer configured to cover and form a seal over the wound contact layer and the indicator material layer.

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 a skin perfusion pressure determination device. In some embodiments, a skin perfusion pressure determination device can include a sensor module having a first sensor for sensing a first parameter associated with a pressure exerted on a target area by the sensor module and a second sensor for sensing a second parameter associated with an amount of blood perfusion at the target area. In some embodiments, the first sensor and the second sensor can be arranged such that, when the sensor module is pressed against the target area the first sensor produces an output corresponding to the sensed first parameter and the second sensor produces an output corresponding to the sensed second parameter.
