A packaged kit of parts is provided for use with a selectively configurable wound dressing. The kit includes a piercing tool configured to pierce a covering layer of the wound dressing to produce an aperture therein and thereby configure the wound dressing for use in a pressure gradient wound therapy system. The kit may also include a) packaging indicating that the piercing tool is configured to pierce a covering layer of a wound dressing; (b) instructions instructing a user as to how to use the piecing tool; (c) one or more selectively configurable wound dressings; (d) a source of non-atmospheric pressure; (e) a port to connect the wound dressing to a source of non-atmospheric pressure; or (f) tubing for connection between a wound dressing and a source of non-atmospheric pressure. The kit is arranged within a sealed package.

A port is provided for use with a wound dressing. The port has piercing means to change the configuration of wound dressing for use in a pressure gradient wound therapy apparatus or for use without a pressure gradient wound therapy apparatus. The port is for connecting a non-atmospheric pressure source to a wound dressing. It comprises a first aperture configured to connect to the non-atmospheric pressure source; and a wound dressing contact surface. The wound dressing contact surface includes a second aperture in fluid communication with the first aperture and configured to allow fluid communication with the wound dressing. The piercing means is configured to pierce the wound dressing as the wound dressing contact surface of the port is applied to the wound dressing.

A wound dressing for use in the application of negative pressure to a wound, comprising a support member and a cover member positionable over the wound in use. The support member can have a first support element having a first portion aligned with a first axis and a body portion coupled with and extending away from the first portion, and a second support element having a first portion aligned with the first axis and a body portion coupled with and extending away from the first portion of the second support element. At least the body portion of each of the first support element and the second support element can be independently rotatable about the first axis. The support member can support at least a middle portion of the cover member above a surface of the wound so as to define a space between the wound cover and the wound.

A protective dressing includes an outer dressing and an adhesive layer. The outer dressing includes an opening and a cavity sized to receive a phase-change material (PCM) insert inserted through the opening. The adhesive layer is configured to adhere to a patient's skin surrounding an anatomic site. When adhered to the patient's skin, the PCM insert modifies the patient's skin at the anatomic site. The PCM insert may be removed and replaced with another PCM insert. For example, a warm PCM insert may be replaced with a refrigerated PCM insert. The opening of the outer dressing may be self-sealing. The opening of the outer dressing may be sealed with an upper layer dressing coupled to the PCM cooling insert.

A multi-layered wound dressing including a fibrous absorbent layer for absorbing exudate from a wound site. The wound dressing also includes a support layer configured to reduce shrinkage of at least a portion of the wound dressing.

The wound therapy apparatus may include a wound interface sealingly securable to the skin surface around a wound bed to encloses the wound bed within an enclosed space that is fluid-tight. The wound interface may be sufficiently deformation resistant to distend at least a portion of the wound bed into the enclosed space when pressure p.sub.0 within the enclosed space is less than ambient pressure p.sub.amb. Fluid may be communicated with the enclosed space when the wound interface is sealingly secured to the skin surface in order to vary a pressure p.sub.0 within the enclosed space periodically over the pressure range p.sub.min≤p.sub.0≤p.sub.max. The variation of the pressure p.sub.0 may distend the wound bed into communication with a pad received within the enclosed space and decreases the wound bed contact with the pad. Related methods of use of the wound therapy apparatus are also disclosed.

Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

Apparatus for the application of topical negative pressure therapy to a wound site is described, the apparatus comprising: a wound contacting element for retaining wound exudate fluid therein; a wound covering element that provides a substantially airtight seal over the wound contacting element and wound site; a vacuum connection tube connecting a wound cavity to a vacuum source; and a vacuum source connected to a distal end of the vacuum connection tube.

Disclosed embodiments relate to apparatuses and methods for wound treatment. A wound dressing apparatus can comprises a wound contact layer, at least one absorbent layer, an electronics unit comprising a negative pressure source unit, and a cover layer. The electronics unit can comprise a plurality of sensors positioned on a printed circuit board and an inlet protection mechanism of the negative pressure source unit comprises a first recess in fluid communication with a first sensor and the outlet or exhaust mechanism negative pressure source unit comprises a second recess in fluid communication with a second sensor.

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).
