Dressings for tissue treatment with negative pressure and methods of assembling the dressings for tissue treatment with negative pressure are disclosed. A method of assembling a dressing, which may comprise at least three layers assembled in a stacked relationship, may comprise providing an assembly station having at least one retaining pin, placing a first layer on the assembly station, placing a second layer on the assembly station, and bonding the second layer to the first layer. The first layer may comprise a plurality of apertures, at least some of which may be engaged by the retaining pins, and the second layer may comprise fluid restrictions and alignment areas for engaging with the retaining pins so that the fluid restrictions may be aligned with the apertures of the third layer.

A dressing for treating a tissue site with negative pressure may comprise a cover having an adhesive, a manifold, a perforated polymer film, and a perforated silicone gel having a treatment aperture. The cover, the manifold, the perforated polymer film, and the perforated silicone gel may be assembled in a stacked relationship with the cover and the perforated silicone gel enclosing the manifold. The perforated polymer film may be at least partially exposed through the treatment aperture, and at least some of the adhesive may be exposed through the perforated silicone around the treatment aperture.

A system or device for skin closure comprises an elastic flat flexible tape elongated along a longitudinal axis and having a lower side and an opposing upper side, said tape having a pressure sensitive adhesive on at least a portion of the lower side, said tape having a plurality of openings arranged side-by-side with spaces between said openings oriented across the longitudinal axis.

A dressing including a film which is impermeable to fluids and permeable to water vapor, and the entire surface of which is covered by a perforated reinforcement coated with a medically acceptable adhesive which is the same or different on each of the faces thereof, the face opposite to the face in contact with the impermeable film of an adhesive being partially covered by an absorbent pad, The dressing further includes a layer for distributing the fluids which is positioned between the impermeable film and the perforated reinforcement.

An adhesion material configured to be applied on a skin of a subject comprising a polymer molecular chain composition comprising polyethylene glycol 200 (PEG 200), polyethylene glycol 400 (PEG 400), citric acid, ascorbic acid, at least one of a sugar and a sugar alcohol, and at least one fatty acid.

Hydrocolloid adhesive compositions, wound dressings comprising hydrocolloid adhesive compositions and methods of producing such compositions are provided. A hydrocolloid adhesive composition comprises a base polymer, a hydrocarbon tackifier, an absorbent, and a plasticizer. The hydrocarbon tackifier may comprise a cycloaliphatic hydrocarbon modified with aromatic functional groups. A wound dressing comprising the hydrocolloid layer is disposed on a carrier film. The wound dressing may comprise a discontinuous hydrocolloid layer. The hydrocolloid adhesive compositions are substantially transparent to improve visibility through a dressing. The compositions may further include materials that reduce allergic reactions by the user.

A removably attachable phototherapy and vibration system for attachment to and treatment of skin beneath the eyes includes a therapeutic lamp platform for radiant lamps such as LEDs disposed in an assembly, and including a vibrating element, facing towards a patient and a plurality of light apertures substantially aligned with the LEDs for communicating lamp radiation from the lamps to a user. The lamps, vibrating element and associated circuitry are disposed so that the attachable surface is relatively smooth and seamless towards the patient. The system includes two devices one for the right and the other for the left eye of the user. Each device is attachable to beneath each eye with a suitable adhesive such as a reusable silicone strip. The system includes a charging dock for storing and charging the devices.

A skin patch for the UV protection is contemplated as being formed from a vulcanized silicone substrate, an adhesive gel coating adhered to the internal surface of the silicone substrate, and a release liner removably attached to the adhesive gel coating, wherein following removal of the release liner from the adhesive gel coating, the coating is operative to enable adherence of the skin patch to skin. The skin patch is further contemplated as being operative to at least partially absorb solar ultraviolet radiation via the vulcanized silicone substrate or the adhesive coating additionally comprising at least one UV-blocking compound having an absorption peak in the ultraviolet spectrum.

A dressing for treating a tissue site with negative pressure, having an integrated sensor comprising a force or load measurement sensor. The sensor may telemeter to a therapy system the deformation of the dressing as the dressing is pushed into the tissue site during the application of negative pressure to the tissue site. The sensor may measure the force that is applied to the dressing. Measurements of the force applied to the dressing may be taken using the sensor on a periodic basis during negative-pressure therapy to enable monitoring of the fill level of the tissue site as granulation tissue fills the tissue site. Monitoring of the force applied to the tissue site over the course of negative-pressure therapy may assist a clinician in making decisions on how to manage and treat the patient, as well as providing confirmatory data about the efficacy of the therapy.
