SKIN-CONTACT PRODUCT HAVING MOISTURE AND MICROCLIMATE CONTROL

摘要

Skin-contact products with a transpiration function such as medical devices or medicinal products, of which face masks, aspirators, ventilators, breast pumps or wound dressings are examples are described especially a skin-contact product with a transpiration function with an improved microclimate at a patient interface material-skin contact area. In an embodiment a material system (10, 20, 30) is described that comprises a hydrophobic silicone base material (11, 21, 31) and a hydrophilic silicone material (12, 22, 32) that is combined with the hydrophobic base material (11, 21, 31). At least a part of the hydrophilic material (12, 22, 32) is in contact with a moist surface (50). The hydrophobic base material (11, 21, 31) provides mechanical and dynamical stability of the material system (10, 20, 30). The hydrophilic material (12, 22, 32) allows for uptake or for diffusion of moisture away from moist surface (50). The material system (10, 20, 30) is utilized to fabricate a patient interface material (41) and forehead pad (42) of a user or patient interface, such as face mask (40), for example, a patient interface mask for positive air pressure therapy. Furthermore, a novel composition for the preparation of hydrophilic silicone materials, suitable for use in the material system (10, 20, 30), is disclosed.
