Systems, methods, and apparatuses for forming a multi-function core for a dressing are described. The multi-function core includes a contact layer configured to be positioned adjacent to a tissue site, a wicking layer adjacent to the contact layer, an ion exchange layer adjacent to the wicking layer, an absorbing layer adjacent to the ion exchange layer, a blocking layer adjacent to the absorbing layer, and an odor-absorbing layer adjacent to the blocking layer. The contact layer, the wicking layer, the ion exchange layer, the absorbing layer, the blocking layer, and the odor-absorbing layer are coextensive and formed from a plurality of fibers disposed in a fibrous web. Methods of manufacturing the multi-function core are also described.

A method for treating a wound that includes incorporating a wound dressing comprising a plurality of fibers, each fiber having a length of at least two (2) inches, into a wound to cause the walls of the wound to remain apart and allow the wound to heal from the inside to the outside, and removing the wound exudate.

Methods and apparatuses for detecting full waste canister and/or fluid flow path blockage conditions are disclosed. Also disclosed are methods and apparatuses for controlling a pump. In some embodiments, flow of fluid can be restricted in a portion of the fluid flow path. A controller can be configured to compare a difference in pressure values upstream and downstream of a fluid flow restrictor to a pressure difference threshold, and determine based on the comparison whether to activate an alarm indicating the full waste canister condition or the fluid flow path blockage condition. The controller can be additionally or alternatively configured to determine a fluid flow using a flow meter, open a selectable valve in response to a comparison of the fluid flow with a fluid flow threshold, determine fluid flow after opening the valve, and determine based on the fluid flow after opening the valve whether to activate the alarm.

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a wound dressing, negative pressure source, user interface, sensor, and control circuitry. The user interface can receive an activation input. The sensor can detect whether the wound dressing is positioned over a wound. The control circuitry can cause supply of negative pressure in response to receipt of the activation input and a determination that the sensor detects that the wound dressing is positioned over the wound. In addition, the control circuitry can prevent supply of negative pressure in response to a determination that the sensor does not detect that the wound dressing is positioned over the wound.

In some embodiments, a wound monitoring and/or therapy apparatus can include a wound dressing configured to be positioned over a wound. The wound dressing can support one or more sensors. The one or more sensors can include an optical sensor array cluster, which can include an optical sensor and single light source. In some embodiments, the wound dressing can include a substantially stretchable wound contact layer that includes a wound facing side and a non-wound facing side opposite the wound facing side, the wound facing side configured to be positioned in contact with a wound. The non-wound facing side of the wound contact layer can support a plurality of electronic components and a plurality of electronic connections that connect at least some of the plurality of the electronic components. The electronic components can include one or more sensors configured to obtain measurements of the wound or the periwound, or both.

Embodiments of reduced pressure systems and methods for operating the systems are disclosed. In some embodiments, a system can include a source of negative pressure and a controller configured to present GUI screens for controlling and monitoring operation of the system. The controller can be configured to receive, via the GUI, an adjustment of a negative pressure therapy parameter and adjust (or cause adjustment) of the operation of the negative pressure source based on received adjustment. The controller can be further configured to record historical data parameters associated with negative pressure therapy parameters. The controller can also be configured to transmit (or cause transmission) over a communication channel at least some of recorded historical data. The system can be configured to provide external connectivity for accomplishing various activities, such as location tracking, compliance monitoring, tracking of operational data, remote selection and adjustment of therapy settings, etc.

To offload forces from a tissue site being treated with reduced pressure, an offloading pressure component may be used as part of a reduced-pressure treatment system. A reduced-pressure source of the reduced-pressure treatment system vents positive pressure exhaust into the offloading pressure component to inflate the offloading pressure component. The offloading pressure component disperses forces away from the tissue site. Other devices, methods, and systems are presented.

Systems and methods for wound drain management. Certain embodiments include an infection indicator and/or a coupling device configured to such that a wound drainage container can rotate in relation to a mounting device.
