A volume of a wound is estimated using a dynamic pressure response measured during instillation of fluid to the wound using a negative pressure wound therapy system. A previously estimated wound volume may be used to detect and prevent overfill of fluid to the wound during future instillation events. For example, real-time pressure measurements may be compared to model data representative of expected pressure at a wound having a volume equal to the previously estimated wound volume, with instillation being stopped if the observed pressure varies from the expected pressure. A comparison of a total volume of fluid instilled to the wound may also be compared to the previously estimated wound volume to prevent overfill. The comparison of wound volume estimated based on an instillation event may also be compared to a wound volume estimated using other methods to provide a higher confidence wound volume estimate.

The present disclosure describes techniques for providing directed instillation or irrigation of fluid during wound therapy to deliver cleansing fluid precisely onto a wound to improve wound cleansing. Directed instillation or irrigation of fluid onto wounds using techniques of the present disclosure can accelerate wound healing and provide improved patient outcomes. One example of the present disclosure is a device for providing directed fluid irrigation to a wound. The device can include an irrigation tube extending between a first end and a second end, with the second end having a perforated section or a non-perforated closed section. The device can further include a foam structure arranged around the perforated section, with the foam structure being configured to dispense fluid received from the perforated section uniformly into a wound for cleansing. The perforated section can include a plurality of perforations or a plurality of perforated irrigation tubes in examples.

This disclosure is directed towards the use of intelligent disposables in wound treatment devices and systems, such as negative pressure wound therapy devices and systemsand liquid jet debridement dev

The present disclosure generally relates to a negative wound therapy (NPWT) system (100) comprising a mobile negative pressure device (101), a tubing assembly (105) and a non-absorbent or an absorbent dressing (104).

A disposable device 1000 for use with a wound treatment or monitoring system, comprising a substrate 500A (Figure 4A) or housing, and electronic circuitry at least partially supported by the substrate

The volume of the wound is estimated using the dynamic pressure response measured during infusion of fluid into the wound using a negative pressure wound therapy system. The previously estimated wound volume may be used to detect and prevent overfilling of the wound with fluid during future infusion events. For example, real-time pressure measurements can be compared to model data representing the expected pressure in a wound having a volume equal to the previously estimated wound volume, and infusion is stopped if the observed pressure differs from the expected pressure. The total volume of fluid infused into the wound can be compared to the previously estimated wound volume to prevent overfilling. The wound volume estimated based on the infusion event can also be compared to wound volumes estimated using other methods to provide a more reliable wound volume estimate.

In some embodiments, a wound therapy apparatus includes a wound dressing configured to be positioned over a wound, the wound dressing including a substantially stretchable wound contact layer supporting a plurality of electronic components and a plurality of electronic connections that connect at least some of the plurality of the electronic components. The wound contact layer can include a first plurality of flocked fibers positioned on a wound facing side of the wound contact layer, the first plurality of flocked fibers including soft material configured to cushion the wound contact layer when the wound dressing is positioned over the wound. The wound contact layer can include a second plurality of flocked fibers positioned on a non-wound facing side opposite the wound facing side.

A wound therapy system having a wound dressing for treating a wound includes a sensor that measures a pH level at a wound area. The sensor has a circuit that includes a first electrode and one or more second electrodes. The first electrode has a changeable conductivity that changes according to a hydrogen ion concentration level. The one or more second electrodes are configured with a fixed conductivity that does not change with the hydrogen ion concentration level. The first electrode is coated with a porous protective membrane formed from a sulfonated and / or carboxylated copolymer.

Disclosed herein are systems and devices for wound therapy and related methods of use. The systems and devices for wound therapy and related methods of use disclosed herein may comprise one or more cartridges for preparation of a regenerative epidermal suspension. One or more cartridges for preparation of a regenerative epidermal suspension may comprise a cover with a raised processing opening, a cup that can be received within the raised processing opening and has a screen, and a well plate that is positioned under the cover, has a well, and rotates relative to the cover such that the well aligns with the raised processing opening.
