POLYMERIC FILM DISONTINUITIES IN WOUND CLOSURE DEVICE
The present disclosure relates to a two-component medical device for closing a wound or incision. The two-component device comprising a first and second component, each comprising an adhesive-backed anchoring member having one edge referred to as the wound edge. The adhesive-backed anchoring members are produced from a polymeric film sheet. Disclosed are instances wherein the adhesive-backed anchoring members are characterized by the presence of one or more discontinuities in the polymeric film sheet.
Flexible, adherent, and non-polyurethane film wound drape cover
A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.
ADHESIVE ARTICLE AND METHOD OF MAKING SAME
Various embodiments of an adhesive article and a method of forming such article are disclosed. The adhesive article includes an active pharmaceutical ingredient; a substrate having a first surface and a second surface including a first area and a second area; and a first adhesive layer disposed on the first area of the second surface of the substrate. The active pharmaceutical ingredient is present in the first adhesive layer at a first concentration. The adhesive article also includes a second adhesive layer having a first portion that is in contact with the first adhesive layer and a second portion that is disposed in the second area of the substrate. The active pharmaceutical ingredient is present in the second adhesive layer at a second concentration. The second concentration is less than the first concentration.
WOUND DRESSING AND A METHOD FOR PRODUCING THE SAME
The invention provides a wound dressing made by an ex vivo formed combination of fibrinogen and/or fibrin containing-liquid formulation and an oxidized cellulose (OC) backing; and use thereof.
ARRAY OF ABSORBENT DRESSINGS FOR THE TREATMENT OF WOUNDS
Array for the treatment of wounds comprising a first absorbent wound dressing (10, 30) that is non-adhesive and a second absorbent wound dressing (20, 40) that is adhesive, wherein the first wound dressing (10, 30) comprising a first absorbent pad (12, 32) comprising superabsorbent fibers and/or particles, and wherein the second wound dressing (20, 40) comprises a second absorbent pad (22, 42) comprising superabsorbent fibers and/or particles, characterized in that the second wound dressing (20, 40) comprises means for the adhesive fixation of the second wound dressing (20, 40) to the skin of a patient, wherein the means for the adhesive fixation comprise a skin-friendly silicone adhesive (23b, 43b).
SECUREMENT STRIP WITH ENHANCED THICKNESS
The instant invention relates to a multipurpose glueless securement means for fastening/sealing applications which traditionally are accomplished by the use of a disposable adhesive bearing tape/or a disposable tape utilizing mechanical fastening devices. More particularly, the invention relates to the use of a high tensile strength polyvinyl chloride (PVC) strip which possesses self-adhesive properties and can be reused virtually indefinitely. The elongated rectangular strips of tape are comprised of 14.1 to 16-gauge double pressed polished PVC. This thickness provides enhanced strength. Due to the unique chemical properties of the invention it has a wide range of useful applications from traditional sealing or binding applications to applications involving contact or application with external skin surfaces.
Switchable adhesives
The present invention provides switchable adhesives comprising a mixture, in proportions by weight, of 20% to 98% of an adhesive, 2% to 80% of curable molecules and 0.05% to 10% of photoinitiator in which the weight proportion of the adhesive is calculated on the basis of its dry weight and wherein the adhesive includes an internal cross-linker for cross-linking the adhesive during drying to provide a cohesive strength of between 5 and 100 N/12.7×12.7 mm measured according to FINAT test method No. 18. Preferably, the adhesive and curable molecules are mutually soluble when dry, or the curable molecules and adhesive may be uniformly dispersed in each other. Preferably the amount of adhesive in the mixture is in the range 40% to 98% by weight, more preferably 60% to 95% by weight, even more preferably 70% to 85% by weight. Preferably the proportion of curable molecules in the mixture ranges from 2% to 60% by weight, more preferably 5% to 40% by weight, even more preferably 15% to 30% by weight. Preferably, the photoinitiator is present in the mixture in the proportions 0.5% to 5% by weight, more preferably 1% to 3% by weight. Such switchable adhesives are useful in medical dressings and other removable sheet products, and may be simply prepared by stirring the adhesive, the curable molecules and the photoinitiator together at room temperature.
Dressing
A dressing includes a drape, a pressure-sensitive acrylic-based adhesive on a skin-facing surface of the drape, an island of absorbent material, a silicone gel backing film, and a silicone gel on the silicone gel backing film. The drape is a thin film capable of maintaining a negative pressure underneath the drape upon application of a vacuum. The island of absorbent material has a smaller area than the drape and is applied onto the skin-facing surface of the drape. The silicone gel backing film has a frame shape and a smaller footprint than the drape and a larger footprint than the island of absorbent material.
WIRELESS PRESSURE ULCER ALERT DRESSING SYSTEM
A wireless pressure ulcer alert dressing system for warning a patient or caregiver that soft tissue pressure or health condition has exceeded some predetermined level that over time would necessitate moving the patient to prevent or at least reduce a risk of soft tissue damage. The dressing assembly is adapted to be applied to or near a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure and other health characteristics sensed at the surface. The dressing assembly generates output signals based on the electrical outputs and corresponding to whether or not the soft tissue pressure has exceeded a predetermined pressure level during the preselected time period. The dressing assembly includes a pocket formed therein for removable, secured and protected insertion of a variety of different sensors such as multiple pressure sensors.
APPARATUS AND METHOD FOR A TEMPERATURE RELEASED ADHESIVE STRUCTURE FOR USE WITH BANDAGES
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.
