20090318045 | Functional Surface Finish and Method of its Application to a Material Surface - The present invention relates to a functional surface finish comprising a finishing agent having a functional part and a surface-anchoring part, wherein said functional part and said surface-anchoring part are coupled via a thermally reversible covalent bond. The present invention further relates to compositions for finishing a surface, to methods of finishing a material surface, to material surface comprising a surface finish and to a method of re-functionalizing a material surface. | 12-24-2009 |
20120285469 | TEXTURED/POLISHED RESPIRATORY MASK SEAL AND MASK - A seal for a respiratory mask that includes a first end portion adapted to be coupled to a mask shell, a second end portion for sealing engagement with a face of a patient, and a sidewall extending between the first end portion and the second end portion. At least a portion of the second end portion includes a textured area having a predetermined pattern. The area of increased surface roughness provides the patient contacting portion of the seal with a silky feeling to maximize patient comfort and the effectiveness of the seal without impairing the sealing ability. | 11-15-2012 |
20140113986 | WATER-ABSORBING ELASTOMERIC MATERIAL - This invention relates to a rubbery or elastomeric polymer material taking up more than 5% by weight of water and at most 500% by weight of water after immersion in demineralized water at room temperature for a sufficient time to reach saturation, comprising: (a) repeating units from one or more hydrophobic organic monomers, and (b) repeating units from one or more monomers (a) being modified with one or more hydrophilic side groups. The rubbery or elastomeric polymer material may be in the form of a sheet, a foam, a coating adapted for adhesion to a substrate, or a fiber. This invention also relates to processes, polymerizable compositions, and foaming compositions for producing such rubbery or elastomeric polymer materials. | 04-24-2014 |
20140130804 | TEXTURED/POLISHED RESPIRATORY MASK SEAL AND MASK - A seal for a respiratory mask that includes a first end portion adapted to be coupled to a mask shell, a second end portion for sealing engagement with a face of a patient, and a sidewall extending between the first end portion and the second end portion. At least a portion of the second end portion includes a textured area having a predetermined pattern. The area of increased surface roughness provides the patient contacting portion of the seal with a silky feeling to maximize patient comfort and the effectiveness of the seal without impairing the sealing ability. | 05-15-2014 |
20140134416 | MEDICAL AND NON-MEDICAL DEVICES MADE FROM HYDROPHILIC RUBBER MATERIALS - This invention relates to medical, health care and non-medical devices comprising a rubbery or elastomeric polymer material taking up more than 5% by weight of water and at most 500% by weight of water after immersion in demineralized water at room temperature for a sufficient time to reach saturation. The material may be in the form of a foam, or in the form of a coating adapted for adhesion to a substrate, or in the form of a sheet, or in the form of a fiber, and may comprise: —repeating units from one or more hydrophobic organic monomers, and —repeating units from one or more monomers (a) being modified with one or more hydrophilic side groups. | 05-15-2014 |
20140349075 | ENGINEERED SURFACE FOR PROVIDING LOW FRICTION AND IMPROVED COMFORT ON DEVICES THAT CONTACT THE SKIN OR OTHER EXTERNAL TISSUE OF THE USER - An apparatus structured to contact external tissue, such as skin, of a user includes an elastomeric contacting portion that is structured to directly engage the external tissue. The contacting portion has an engineered surface ( | 11-27-2014 |
20150013682 | PATIENT INTERFACE DEVICE HAVING AN ENGINEERED SURFACE FOR PROVIDING LOW FRICTION AND IMPROVED COMFORT TO THE USER - A patient interface device includes an elastomeric contacting portion that is structured to directly engage the skin of the user. The contacting portion has an engineered surface that includes a plurality of non-random, predesigned surface features designed to reduce friction and improve user comfort. In one implementation, the pitch between each immediately adjacent pair of the surface features is less than or equal to a predetermined maximum pitch value, and the height of each of the surface features is less than or equal to a predetermined maximum height value. | 01-15-2015 |
20150040909 | USER INTERFACE DEVICE PROVIDING FOR IMPROVED COOLING OF THE SKIN - A number of user interface device embodiments are disclosed that provide for increased cooling of the skin covered by the mask and/or increased flushing of gasses, including CO | 02-12-2015 |
