A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.

A system and method for donning and labeling a body cast provides a protective body cast that is labeled. The system and method provides a protective body cast that forms padded protection around the body of a bedridden patient; and especially around the hip, buttock, and lower extremity pressure points. The body cast is composed of a nanomaterial and serves as an envelope for an inner lining of a softer material such as a composite foam rubber. The body cast is sectioned into a multi-layered enclosing cloth support wrap that is fabricated from a nanomaterial, an inner surface having padding, and at least one auxiliary padding that detachably attaches to the body cast for additional padding. Labels detachably attach to the lower portion of the support wrap for indicating information pertinent to the patient. A caregiver accesses the label to read and mark directly on a bedridden patient.

A hemostatic surface application device having a region of hemostatic foam for contact with a patient's skin where a wound exists or is created, the device includes: a release layer, the release layer in contact with a hemostatic flexible foam section, and a structural foam layer having a front side and a back side surrounding the hemostatic flexible foam layer, forming a generally central hemostatic surface exposed through the front side of the surrounding structural foam layer, and a support layer adhered to the backside of the structural foam layer.

The present invention generally relates to an absorbent component (100) for use in a garment. The absorbent component (100) comprises: a first layer composite (120) comprising a first foam layer (122) and a first liquid impermeable layer (124); an absorbent layer composite (140) bonded to the first liquid impermeable layer (124) for absorbing bodily fluids; and a second liquid impermeable layer (164) bonded to the absorbent layer composite (140) and first layer composite (120) to contain the bodily fluids absorbed by the absorbent layer composite (140), wherein the second liquid impermeable layer (164) forms an opening (166) for receiving the bodily fluids to the absorbent layer composite (140); and wherein the first foam layer (122) is moulded to shape the absorbent component (100).

A binder layer for a laminated wound dressing is brought into contact with a sheet coated with a pattern-coated adhesive sheet. As the binder layer is in contact with the pattern-coated adhesive sheet, a series of closed-loop cuts are made in the binder layer. The closed-loop cuts are made in such a way that the material enclosed by each closed loop is substantially physically separated from the remainder of the binder layer. Then the binder layer is moved away from the pattern-coated adhesive sheet, so that the binder layer and the pattern-coated adhesive sheet are no longer in contact. When the binder layer and the pattern-coated adhesive sheet are moved apart, the material enclosed in the closed-loop cuts—i.e., the cut waste fragments—are retained on the pattern-coated adhesive sheet, ensuring that the binder layer includes a series of cleared perforations.

A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.

An apparatus for applying negative pressure to a tissue site proximate a patient's foot may include a tissue interface, a sole, a toe box, a cover, and an interface. The tissue interface may be configured to be circumferentially disposed around the tissue site. The sole may be configured to support the tissue interface. The toe box may be coupled to the sole. The cover may be configured to be coupled to the leg and to the sole to cover the tissue interface. The cover and the sole may form a chamber containing the tissue interface and may seal the tissue interface within the chamber. The interface may be configured to fluidly couple the tissue interface to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site.

A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.

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.
