A method for calculating range of motion of a patient's jointed limb includes providing one or more locators at an upper limb of the jointed limb, and one or more of the locators at a lower limb of the jointed limb. A first image of the patient's joint in a fully extended position a second image of the patient's joint in a fully flexed position are captured with an imaging device. The method includes identifying positions of the locators of both the first image and the second image, and determining an extended angle of the patient's joint based on the identified positions of the locators of the first image. The method includes determining a flexed angle of the patient's joint based on the identified positions of the locators of the second image. The method includes determining a range of motion angle based on the extended angle and the flexed angle.

In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly configured to offload fluid extracted from the tissue site away from an articulation area at the tissue site. Other features may be associated with the dressing including, without limitation, a base layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly including a fluid restraint configured to reduce a fluid capacity of the fluid management assembly proximate to the fluid restraint. Other features may be associated with the dressing including, by way of example and without limitation, abase layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

A dressing includes an evaporative film layer having a wound-facing side and a non-wound facing side. The evaporative film layer has a high moisture vapor transfer rate. The dressing includes a carrier film layer coupled to the non-wound-facing side of the evaporative film layer. A plurality of holes extends through the carrier film layer. The dressing includes a superab sorbent layer coupled to the wound-facing side of the evaporative film layer and a wicking layer coupled to the superab sorbent layer. The superab sorbent layer is positioned between the wicking layer and the evaporative film layer. The wicking layer is configured to wick fluid from a wound, the superab sorbent layer is configured to absorb fluid from the wicking layer, and the evaporative film layer and the carrier film layer allow evaporation of fluid from the superabsorbent layer through the holes. The carrier film layer provides structural support to the evaporative film layer.

A system for treating a deep abdominal wound. The system includes a wound dressing. The wound dressing includes a visceral-protective layer, a compressive layer, and a sealing layer. The visceral-protective layer is configured to be positioned in an open abdomen. The compressive layer is configured to be disposed proximate to the visceral-protective layer. The compressive layer includes a pattern of voids configured for anisotropic collapse of the compressive layer when under negative pressure. The sealing layer is configured to form a sealed space in the open abdomen. A negative pressure source configured to provide negative pressure to the compressive layer.

A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

A dressing for managing an incision and surrounding tissue where edema and swelling may be present post-operation. The dressing may maximize coverage of area in articulating joints, such as a knee or elbow, while allowing for substantial range of motion. In some embodiments, the dressing may comprise an adhesive border configured to be adhered to skin around an articulating joint, a skin-interfacing fabric for minimizing skin irritation, a foam body for manifolding negative pressure and absorbing exudate and other body fluids, and a thin polymer film cap for sealing the assembly so negative pressure can be maintained throughout the dressing.

In some illustrative examples, a medical drape suitable for treating a tissue site may include an adherent surface including first adherent force profile oriented along a first axis and a second adherent force profile oriented along a second axis. The first adherent force profile may have an average force less than an average force of the second adherent force profile. Other apparatuses, systems, and methods are also provided.
