Publication number: 20070095349Abstract: The invention relates to a respiratory mask comprising a mask body (2), a sealing edge (3) and an inhalation device. Said device can be improved such that gas can be evacuated from the inhalation device without noise disturbance. The aim of the invention is achieved by virtue of the fact that the inhalation device comprises a plurality of lamella-type, partially overlapping membrane elements (8) which can be unfolded by the respiratory gas flow and which are arranged on the mask body (2).Type: ApplicationFiled: October 5, 2004Publication date: May 3, 2007Applicant: DRAGERWERK AGInventors: Hans-Ulrich Hansmann, Gotz Kullik, Jorg-uwe Meyer

Patent number: 6952947Abstract: A measuring head for the determination of the concentration of a paramagnetic gas in a gas sample has first and second housing parts (21, 2) made of a steel alloy for accommodating a magnet coil body (4, 5) each. The magnet coil bodies extend concentrically around the central axis of each housing part (21, 2). Metallic bars (31, 3), which are used as magnet poles for the measuring head, are located at spaced locations with a defined air gap in the assembled state of the measuring head. The bars are arranged in the center of the measuring head in the area of the central axis of the housing parts (21, 2). A sample gas cuvette support (6) is provided in the air gap between the housing parts (21, 2) for positioning a sample gas cuvette holder (1). The sample gas cuvette support (6) is provided with a gas inlet and gas outlet (8, 81).Type: GrantFiled: July 2, 2003Date of Patent: October 11, 2005Assignee: Dräger Medical AG & Co., KGaAInventors: Günter Steinert, Alfred Kelm, Hans-Ulrich Hansmann, Hartmut Stark, Peter Dreyer

Patent number: 6895962Abstract: A compact device for supporting respiration is provided making possible a mobile, autonomous, pressure-supported respiration of patients near the lungs with very small dead spaces and flow resistances. The device is especially useful for medical applications. The device includes a rotary compressor (3) with an electric drive motor provided with a filter (7) arranged directly upstream in the direction of flow. The compressor (3) is arranged directly upstream of a breathing mask (2) or a breathing tube. A control unit (6) is provided for setting respiration pressure on a basis of speed of rotation. The control unit (6) is connected to the drive motor of the compressor (3).Type: GrantFiled: November 27, 2002Date of Patent: May 24, 2005Assignee: Dräger Medical AG & Co.

Patent number: 6474960Abstract: A radial compressor is provided for respiration purposes. The sound emissions generated by deflections and separations of the gas flow in the compressor wheel and the housing of the radial compressor and by the high-speed motor of the radial compressor are reduced. This is achieved with a specially shaped passage channel (4) for the volume flow, which exerts a stabilizing effect on the volume flow utilizing the Bernoulli principle of flow. Additional sound reduction is provided by using a separate mass (8) arranged between the motor (6) and the housing (3), which absorbs the sound energy generated by the high-speed motor (6). Also sound reduction is provided by suspending the radial compressor with membranes in a closed capsule.Type: GrantFiled: August 30, 2000Date of Patent: November 5, 2002Assignee: Dräger Medizintechnik GmbHInventor: Hans-Ulrich Hansmann
