The present disclosure provides a wound dressing in the form of a bandage having a seal strength that is sufficient to allow it to be used in medical applications, and a low trauma, peel-off releasability for the convenience and comfort of the patient. An adhesive for use with such a bandage is also provided. The adhesive comprises a polyurethane adhesive including a mixture of: (a) a polyol mixture, (b) an isocyanate, and (c) a catalyst mix. The adhesive may have a thickness in the range of about 50 to about 525 pm and may have an adhesion value of less than about 150 g/cm against a metal plate.

A multi-layer dressing for treating tissue with negative pressure, instillation, or both. In some embodiments a first layer may be formed from reticulated foam having a series of holes. A second layer disposed adjacent to the first layer may be formed from a perforated polymer. The dressing may optionally include a third layer formed from a soft polymer, such as a silicone gel. The third layer may also have perforations or apertures. The third layer is generally oriented to face a tissue site, and may be disposed adjacent to the first layer so that the first layer is disposed between the third layer and the first layer. The perforations or apertures in the third layer may be registered with one or more perforations in the first layer.

A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

The invention provides articles of manufacture, compositions, and methods related to a therapeutic elastic bandage such as a kinesiology tape comprising a medicament to modulate the endocannabinoid system of a subject.

The present invention chiefly aims at providing a new patch which is excellent in the fixability to the skin, regarding the patch carrying a microneedle array.

The present invention, for example, can include a patch in which a microneedle array is carried on a surface of the pressure-sensitive adhesive layer-side of an adhesive member which is characterized in setting up a pressure-sensitive adhesive on one surface of a support and in having a rigidity of 1.3 MPa.Math.mm.sup.4 or more, the adhesive member thereof, and the like.

The patch or the like of the present invention is useful for pharmaceuticals and the like because the puncturability of microneedle is improved, and a microneedle array can be firmly fixed to the skin, and drugs can be quantitatively administered without waste.

Devices, kits and methods are used for wound healing, including but not limited to the treatment, amelioration, or prevention of scars and/or keloids, and include packaging, manipulation elements, applicator and/or tensioning device that are used to apply and/or maintain a strain in an elastic dressing.

The present invention is directed to a wound dressing, surgical tape or plaster 10 comprising an absorbent pad 14 and an adhesive part in which the adhesive part is an adhesive dissolvable paper 12. Another aspect of the invention is directed to a bandage 30 of elongate form in which sections 32 of the bandage 30 can be of a woven or non-woven fabric, comprising multiple sections 32, wherein the sections 32 are held together via water-soluble fibre material.

A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.

An adhesive article that remains securely bonded to a substrate until a stimuli is applied. The article may be embodied as an adhesive tape, a bandage, or as other articles. The stimuli may be a change in temperature or application of a reduction that causes a structure within the article to break, creak, or otherwise disrupt to expose the adhesive to a solvent, such as via a difference in Coefficient of Thermal Expansion (CTE) or by exposing the article to a glass transition temperature.
