摘要:
A headgear for securing a patient interface to a patient's head includes a rear member and a pair of lower strap members. Each lower strap member is sized and configured to be positioned on a respective side of the head of the patient when the headgear arrangement is disposed on the head of the patient. Each lower strap member includes a free end that is selectively directly coupleable to the patient interface. The arrangement also includes a pair of strap management arrangements, with each arrangement positioned on a respective side of the headgear and structured to locate/hold the free end of a lower strap member of the pair of lower strap members in a predetermined location on the respective side of the head of the patient when the headgear is positioned on the head of the patient and the free end is not directly coupled to the patient interface.
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 is described that comprises a hydrophobic silicone base material and a hydrophilic silicone material that is combined with the hydrophobic base material.
摘要:
An actuator device comprises a stack formed from a plurality of photoresponsive layers, which deform in response to light, which are partitioned by respective deformable non-photoresponsive layers. The deformable non-photoresponsive layers guide light between and to the photoresponsive layers, and can follow the deformation of the photoresponsive layers.
摘要:
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 (64A, 64B) that includes a plurality of non-random, predesigned surface features (70, 74B, 76B, 78B) designed to reduce friction and improve user comfort. In one implementation, the pitch (P) between each immediately adjacent pair of the surface features (70, 76B) is less than or equal to a predetermined maximum pitch value, and the height (H) of each of the surface features (70, 76B) is less than or equal to a predetermined maximum height value.
摘要:
In a method for grinding coffee beans (5), the beans (5) are ground off bit by bit by applying a device (1) comprising two tools (20; 40, 42), wherein one of the tools (20; 40, 42) is a grinding tool (20) having an abrasive surface (21), wherein the beans (5) and the abrasive surface (21) are made to contact each other and to perform a relative movement with respect to each other, and wherein another of the tools (20; 40, 42) is a bean delimiting tool (40, 42) having a surface (44) against which the beans (5) are retained during the time that they are in contact with the abrasive surface (21). By grinding off coffee beans (5) instead of crushing coffee beans (5) in a conventional manner, it is achieved that the grinding process can be performed at a relatively high speed and a relatively low torque.

摘要:
The present invention relates to a patient interface and a patient interface system comprising a responsive material and a method for preventing the formation of red marks due to wearing a patient interface (10) that is pressing against the skin of a patient (14) for a longer time and/or for reducing air leakages of the patient interface (10) that may result from an unintended shift of the patient interface (10) on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element (18, 26) on the patient (14), and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.
