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.

Abstract: A negative pressure wound therapy system can include a source of negative pressure configured to be fluidically connected by a fluid flow path to a wound covered by a wound dressing and further configured to provide negative pressure to the wound and a turbine configured to be positioned in the fluid flow path and further configured to monitor a rate of a flow of fluid in the fluid flow path responsive to a rotation of the turbine caused by the flow of fluid.

Abstract: Disclosed embodiments relate to a wound therapy system that can deliver nitric oxide and apply negative pressure to a wound. The wound therapy system can include a wound dressing for placement over the wound, a source of negative pressure connected to the wound dressing, a source of nitric oxide connected to the wound dressing, and a controller configured to regulate nitric oxide delivery and negative pressure application to the wound dressing. The controller can be programmed to deliver various concentrations of nitric oxide to the wound dressing at various times over the course of treatment of the wound. The controller can also be programmed to apply various levels of negative pressure to the wound dressing at various times over the course of treatment of the wound.

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: 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 dressing.
