Abstract: 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.

Abstract: An apparatus for applying negative pressure to a tissue site of a patient may include a tissue interface, a cover, an aperture in the cover, and a sealing member. The tissue interface may have an anatomical shape configured to cover the tissue site. The cover may be configured to cover the tissue interface. The aperture in the cover may be fluidly coupled to the tissue interface. The sealing member may be configured to seal the cover to the patient, wherein the cover and the sealing member are configured to cooperate to form a sealed chamber containing the tissue interface. The tissue interface may be coupled to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site. The source of negative pressure may be coupled to the cover of the apparatus.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A manifold for use with a dressing for treating an area around an extremity of a patient may include a concave recess positioned at a first end of the manifold. A fold axis may bisect the concave recess and extend from the first end of the manifold to a second end of the manifold. A first portion of the manifold may extend orthogonal to the fold axis toward a first side of the manifold, and a second portion of the manifold may extend orthogonal to the fold axis toward a second side of the manifold opposite to the first side. The fold axis may be configured to extend lengthwise along the extremity. Additionally disclosed are other apparatus, dressings, systems, and methods.

Abstract: In some examples, a dressing assembly suitable for treating a tissue site may include a dressing bolster, a sealing skin, and a gasket member. The sealing skin may cover at least a portion of a first side of the dressing bolster while an opposing second side of the dressing bolster may be configured to be positioned in fluid communication with the tissue site. The gasket member may be configured to create a sealed space between the sealing skin and the tissue site. In some examples, the sealing skin may be liquid impermeable and integrally formed with the dressing bolster. Further, in some examples, the dressing bolster may have a contoured shape including a tissue housing. Other systems, dressings, apparatuses, and methods are disclosed.

Abstract: An apparatus for negative-pressure treatment may include an enclosure having a variable volume, a port and an actuation surface, a first one-way valve configured to allow fluid ingress to the enclosure, a second one-way valve configured to allow fluid egress from the enclosure, and an actuator configured to apply a linear force to the actuation surface.
