Abstract: A system for monitoring and tracking swelling of a patient's limb includes a dressing, an imaging device, and processing circuitry. The dressing is positioned on a patient's limb over a wound and includes a pattern indicator. The imaging device is configured to obtain an image of the dressing and the pattern indicator. The processing circuitry is configured to obtain an initial image of the pattern indicator, obtain one or more subsequent images of the pattern indicator at later times, and determine a swelling change of the patient's limb using the initial image and the one or more subsequent images.

Abstract: A pneumatic accumulator may be fluidly coupled between a negative-pressure source and a dressing of a therapy system. The pneumatic accumulator may have a small volume and one or more deformable members that can deform under negative pressure, reducing the volume of the pneumatic accumulator. The pneumatic accumulator can smooth a pressure wave created by the negative-pressure source. The pneumatic accumulator may also provide additional negative-pressure storage capacity to the therapy system. For example, if a leak develops at the dressing, some of the negative pressure stored in the pneumatic actuator may be supplied to the dressing. The pneumatic accumulator may allow for reduced runtime of the negative-pressure source, leading to increased electrical efficiency.

Abstract: A decompression wrap includes an occlusive layer formed as a first strip having a longitudinal axis, a manifold layer coupled to the occlusive layer and formed as a second strip extending parallel to the longitudinal axis. The occlusive layer extends beyond the manifold layer in a first lateral direction perpendicular to the longitudinal axis. The decompression wrap also includes an adhesive provided on the occlusive layer and configured to seal a first longitudinal section of the occlusive layer to a second longitudinal section of the occlusive layer when the decompression wrap is wrapped around a tissue site.
