Abstract: The present invention relates to a planetary wheel (10) for a planetary gear (14) with a planetary wheel bore (28) which runs coaxially or parallel to the planetary wheel axis of rotation (APR) and which at least partially runs through the planetary wheel axis (22). The invention also relates to a planetary carrier (44) for such a planetary wheel (10), comprising a carrier body (46) with a first disk-shaped body (48) which has at least one first bearing recess (60), which has at least one circumferentially extending first catching projection (64), and with a second disk-shaped body (50) having at least one second bearing recess (62), which has at least one circumferentially extending second catching projection (66).

Abstract: A breathing device for placing on a tracheostoma of a patient comprising a cylindrical housing, an annular housing support, a flexible flat part with sealing and adhesive functions, a filter or a speech valve, and a cover plate. The housing comprises, in the wall thereof, recesses for introducing and extracting inhaled air, and on the proximal opening thereof, an outer edge comprises at least three edge segments which are on the outer wall and at least three edge recesses. Holding rods support the filter on the proximal opening, the housing support comprises an annular flange having at least three inner wall support projections and an annular outer wall base. The support projections have a receiving area, the housing support supports the housing with the filter or speech valve into which the edge segment can be introduced in a precise manner into the support projections.

Abstract: A device for inserting into a tracheostoma prosthesis or a thracheostoma plaster comprises a cylindrical housing and a cylindrical valve element, the housing is provided with a first opening for the connection to the stoma of the patient and with at least one second opening on the opposite side, and the valve element in the second opening of the housing is provided to close the second opening. The valve element is configured so that it can be closed manually by means of a finger and can be opened by elastic return, and the housing surrounds the valve element and the valve element receives a moisture and heat exchanging filter. A cylindrical spring element is arranged between the housing and the valve element.

Abstract: A vacuum-assisted drainage system includes a first porous pad that is permeable to liquids and has a through opening in which a fistula adapter is placed on a film provided with perforations, a cover film for covering the first pad and the wound, and for providing a substantially airtight seal around the wound, wherein in the cover film an opening is provided that surrounds the fistula adapter in a substantially airtight manner, and a second porous pad that is permeable to liquids is positioned partially above the first pad on the cover film and is provided with a sealing film for covering the second pad and for providing a substantially airtight connection to the cover film and around the wound, wherein between the first pad and the second pad air guiding routes are provided that pass through the cover film, and an open drainage line is located within the second pad.

Abstract: An attachment device (2) for use in the vacuum therapy of wounds has a vacuum-tight mounting element (6). A conduit is fastening to the upper side of that mounting element in a vacuum-tight manner. The conduit (4) communicates with the wound space through openings (22) in the mounting element (6) and in the vacuum dressing. The conduit (4) is flexible and flat and is connected to the mounting element (6) non-detachably and extensively in a longitudinal section (8) on the wound side over at least 70% of its surface projected perpendicularly onto the mounting means (6). The conduit (4) is made out of a flexible elastomer material of Shore A hardness of no more than 60 and the thickness (D) of the combined conduit (4) and mounting element (6) is no more than 7 mm.

Abstract: A device for insertion in a tracheostoma which includes a cylindrical body having a longitudinal axis, a flexible flange which is provided on an outer surface of the device body and has unfolded configuration which it extends essentially from the outer surface of the body to the outside and has a folded configuration in which it is folded in the direction towards the longitudinal axis of the device body, as well as a pin-shaped insertion aid having a means for retaining the flange in its bided orientation, wherein the flange is formed by at least two wings each of which have a recess proximate a tip of the wing, in which the retaining means is removably introduced, and the wings have a shape memory that orients the wings, when unrestrained, away from the longitudinal axis of the device body.

Abstract: There is provided a neck patch to be adhered on a tracheostoma, which is very light and has a good respiratory activity and an excellent sealing behavior when adhered on top of a tracheostoma in the neck of a patient. The neck patch is made of a thin, planar, flexible foil having a thickness of between 5 and 30 ?m, which is adhesive on its proximal side only and has a centrically arranged hole on its distal side, and around which a hard, round plastic connector disk having a central recess is arranged, the neck patch further comprising a supporting frame that surrounds the outer edge of the film and is approximately five to ten times thicker than the film so that the neck patch can be positioned without being rolled together.
