In some cases, a wound dressing includes a substantially flexible substrate with a first, wound-facing side supporting a plurality of electronic components and a second side opposite the first side, a wicking layer in contact with the second side of the substrate, the wicking layer configured to facilitate passage of fluid, a substantially non-stretchable coating applied to at least some of the plurality of electronic components, a substantially stretchable coating applied to the first side of the substrate, the stretchable coating applied over the substantially non-stretchable coating, a wound contact layer in contact with the stretchable coating, the wound contact layer configured to adhere to a wound, and a protective layer applied to the wound contact layer, the protective layer configured to be removed to expose the wound contact layer. In some cases, a method of manufacturing the wound dressing.

Sensor integrated dressings and systems

A wound treatment apparatus can include a wound dressing configured to be positioned proximate to a wound. Multiple optical fibers positioned at least partly in the wound dressing can include a first optical fiber and a second optical fiber. The wound treatment apparatus can include an emitter and a detector. The emitter can emit first electromagnetic radiation into the first optical fiber so that the first optical fiber passes the first electromagnetic radiation. The detector can generate a signal responsive to second electromagnetic radiation that exits the second optical fiber and contacts the detector.

Optical fibers for optically sensing through wound dressings

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.

Device, apparatus and method of determining skin perfusion pressure

Methods of manufacturing a wound monitoring and/or therapy apparatus and/or wound dressing include positioning electronic components and connections in regions of a substrate that are not configured to be perforated. The methods can also include following a set of rules for positioning the components as well as positioning and shaping the connections based on the constraints stemming from, among other things, the positioning of the perforations on the substrate and with the goal of maintaining acceptable levels of signal integrity. The methods further include manufacturing a multi-layered substrate. Wound monitoring and/or therapy apparatus manufactured using such methods are also disclosed.

Rules for sensor integrated substrates

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 including 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, wherein the first sensor and the second sensor are 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, a proximal end assembly configured to contact the target area, a display to provide feedback of the pressure exerted on a target area and/or the amount of blood perfusion at the target area, and a communication device for providing data transfer from the skin perfusion pressure determination device to a control unit.

Disclosed herein are embodiments of methods of inspection and manufacture of flexible printed circuit boards and flexible sensor sheets, and apparatuses such as wound dressing components utilizing the same. The methods can comprise applying a coating material to a flexible printed circuit board, wherein the coating material comprises a material that will fluoresce when exposed to UV or visible light and the flexible printed circuit board comprises one or more electronic components. The coated flexible printed circuit board can be positioned under UV or visible light to cause the coating material to fluoresce.

Systems and methods for inspection of encapsulation and components in sensor equipped wound dressings

Devices and methods for encapsulating a portion of a wound dressing with biocompatible coating are disclosed. In some embodiments, a method includes coating a first side of a flexible wound contact layer of the wound dressing with a hydrophobic coating. The first side of the wound contact layer can support a plurality of electronic components. The method can further include coating a second side of the wound contact layer opposite the first side with the hydrophobic coating. The wound contact layer can be formed at least partially from hydrophilic material.
