A negative pressure wound therapy device can include a negative pressure source configured to be connected, via a fluid flow path, to a wound, a valve positioned in the fluid flow path and configured to, in an open state, permit supply of negative pressure from the negative pressure source upstream of the valve and, in a closed state, block supply of negative pressure from the negative pressure source upstream of the valve, a flow restrictor positioned in the fluid flow path, and a pressure sensor configured to measure a pressure differential across the flow restrictor. The device can include control circuitry configured to, in a normal operational mode, cause the valve to be in the open state and, in a test mode, perform at least one of a leak test, a flow test, or an excessive pressure test.

Self-testing for negative pressure wound therapy devices

Disclosed embodiments related to a drape for use in a negative pressure wound therapy (NPWT). The drape comprises a cover layer, a spacer layer, and a wound contact layer. The drape further comprises a support layer and a reinforcement member. A negative pressure wound therapy (NPWT) apparatus, such as a suction adapter or a wound dressing may be coupled to the drape applied on a wound. The drape may withstand multiple coupling and decoupling of NPWT apparatuses, and can be stay on the wound during coupling and decoupling of NPWT apparatuses. The drape may be coupled with two or more different types of NPWT apparatuses.

Apparatuses and methods for negative pressure wound therapy

Disclosed embodiments relate to wound therapy apparatuses and methods for use in negative pressure wound therapy (NPWT). Such wound therapy apparatuses and methods may reduce maceration during NPWT. The wound therapy apparatus may include a porous hydrophobic layer surrounded by a hydrophilic ring. The hydrophilic ring may serve to prevent passage of liquid while negative pressure is applied to the wound, but allow liquid passage to an absorbent ring when negative pressure is no longer applied. A transmission layer may also be included, underlying the absorbent layer.
