摘要： A gas mask is provided with a mask body, which is designed to cover the face of a user, and with an opening in the mask body, which is closed by a speech diaphragm (8) in a gas-tight manner. A funnel (4) is directed toward the speech diaphragm with an opening angle in the range of 20° to 90°. The funnel (4) is arranged in front of the speech diaphragm in the interior space of the mask body in order to focus sound waves onto the speech diaphragm.

摘要： The invention relates inter alia to a method for measuring the oxygen saturation of the blood flowing in a peripheral human or animal body part (20), in which electromagnetic radiation (q1′(t), q2′(t)) having a first and a second wavelength is irradiated into the peripheral body part or irradiated through the peripheral body part, the reflected or transmitted radiation (x1′(t), x2′(t)) is measured to form two measurement signals (x1(t), x2(t)), and the oxygen saturation of the blood is determined by evaluating the two measurement signals. According to the invention, provision is made for a mathematical mixing model to be used to evaluate the two measurement signals and a statistical evaluation method to be applied to the two measurement signals, wherein, as a boundary condition, the statistical independence of a useful source signal and an interference source signal is assumed and the useful source signal and the two useful-signal-related filter functions are determined with the aid of the evaluation method and the oxygen saturation of the blood is determined using the three aforementioned signals.

摘要： A system includes a blower filter system (20), having a blower filter device (1), a head piece (21) and a flexible connection hose (22), connecting the blower filter device (1) and the head piece to one another in a fluid-communicating manner. A computer (30) is separated in space from the blower filter system. The computer has a communication interface (31), which is designed to transmit data from the computer to the control unit (6) of the blower filter device and/or to receive data from the control unit of the blower filter device to the computer. The blower filter device has at least one communication interface (7) for transmitting data from the control unit to an external computer and/or for receiving data sent from an external computer to the control unit. A process is provided for checking and setting device-specific parameters of the blower filter device of the blower filter system.
