Abstract: An electrical plug-in connection (100) provides a positive connection of a plug-in element (110) to a receiving element (120) within a medical device arrangement (700). The plug-in element forms a male part with an insertion area (112). The receiving element forms a female part with a receptacle (122) corresponding to the insertion area. In a plugged-together state this provides an electrical connection between a plug-side cable (118) connected to the plug-in element and a receptacle-side cable (128) connected to the receiving element via at least two contact areas. The insertion area is 180° rotationally symmetrical relative to an insertion axis (140) of the electrical plug-in connection. The insertion axis is oriented to an insertion direction, whereby a pole reversal of the electrical plug-in connection is allowed without being mirror symmetrical in relation to a reference plane comprising the insertion axis.

Abstract: The invention relates to a cleaner and/or disinfectant for medical and/or surgical elements and apparatuses which is formulated as a powder. It comprises at least one peroxide, at least one acylating agent for releasing peracetic acid from the peroxide in aqueous solution, and also at least one nonionic surfactant. According to the invention, it is provided that it comprises agents for adjusting a pH of a 2% strength aqueous solution to pH 7.5 to 9 and is formulated as granules, where peroxide and/or acylating agent are coated with nonionic surfactant.

Abstract: A humidifying device for breathing gases. The humidifying device has a housing with a recess, a heater, an evaporating chamber with a water feed, a breathing gas feed channel, a breathing gas outlet channel and at least one float element and at least one filling level indicator. The evaporating chamber can be introduced at least partially into the recess and is in contact with the heater to heat water and is designed to receive water from a water reservoir through the water feed. The at least one float element is guided in a floatingly movable manner on the water and is designed to close the feed of water above a water level set point in the evaporating chamber, and the at least one filling level indicator is designed to recognize the drop of the water level from the water level set point as a function of the position of the at least one float element.

Abstract: The invention relates to a method for the mechanical treatment of a reusable medical product. Said method comprises the following steps: a) the medical product (11) is placed in a closable cassette (14) comprising connections for the supply and discharge of a treatment medium, and comprising at least one inside connection to which rinsable cavities and/or channels for the medical product are connected in such a way that the treatment medium can pass through said cavities and/or channels, b) the cassette (14) is closed, c) a fresh, liquid treatment medium is supplied to the supply connections of the cassette (14), the medium in the cassette (14) coming into contact with the medical product and the treatment being carried out, and the treatment medium flows through the cavities and/or channels; d) the treatment medium is discharged from the discharging connections; and e) the discharged treatment medium is rejected, the temperature of the treatment medium not exceeding 100° C.

Abstract: The invention concerns a method for mechanically cleaning and sterilizing medical and surgical instruments and appliances, which consists in: (a) cleaning the instruments and appliances with an aqueous cleaning solution and (b) sterilizing the instruments and appliances with an aqueous sterilizing solution. The invention is characterized in that chlorine dioxide is released in situ, from chlorite and an acid activator, as disinfectant during the sterilizing step. The invention is based on the use of chlorine dioxide as efficient disinfectant, not requiring separate production of said substance in a chlorine dioxide generator. The inventive method can be implemented in a standard instrument washing machine.
