Abstract: A medical training manikin (1) to simulate spontaneous breathing, comprising a torso containing at least one pneumatic actuator (3) for obtaining raise of the manikin's chest or stomach. The actuator (3) is connected to an accumulator (7) via a control valve (5), which is designed to let air from the accumulator (7) into the actuator (3). The accumulator (7) is designed to be temporarily connected to an external pneumatic source (8) for filling of the accumulator (7) with a pneumatic pressure adequate for repeated actuations by the actuator (3).

Abstract: A sound distributor, for use in a system for distributing physiological sounds in a training manikin, the system comprising at least one acoustic source (5, 6), e.g., a loudspeaker, adapted to convert electrical signals from a signal generator into an acoustic signal. The sound distributor is an air filled structure (17-23), e.g., a pouch or bladder made of a flexible foil, comprising coupling means, e.g., an air filled sound conductor (14-16), for coupling to the acoustic source.

Abstract: A system for communication between sensors in training equipment and electrodes for a defibrillator (AED) or a defibrillator-trainer (AED-T) provides for determining electrode positioning and providing feedback to the user. The training equipment is provided with a non-conductive chest skin, and the communication is wireless and bi-directional. The information from the manikin is generated by a microprocessor with a digital-analog converter. The information signal is transmitted to the sensors in the manikin by use of drivers, which sensors each constitute one half of a non-galvanic coupling, in which the chest skin separates the halves, and the other halves of the non-galvanic couplings are formed by electrodes that are attached to the chest skin, the non-galvanic coupling being in the form of capacitors or coils.

Abstract: A system for detecting an electrode position for a defibrillator on a manikin includes electrical conductive faces that are provided in hidden positions under the manikin skin in locations that correspond to correct and incorrect positions for placement of the defibrillator respectively, and which constitute the respective halves of a capacitor. The faces are connected to a first and a second oscillator respectively, which oscillators emit two different frequencies. A position indicator may be arranged inside the manikin, which indicator will give notification to the user by the use of light sources, e.g., light emitting diodes that shine through the manikin skin, or by activation of a sound signal. A signal analyzing device judges the correctness of the electrode positions via output from the oscillators.
