  • Pulse device for creating a simulated feelable heart's pulse to train feeling and recognition of pulse
    Patent number: 6007342
    Abstract: A device for simulated heart's pulse in manikins and apparatus used in connection with training how to feel and recognize pulse, comprising an electric linear motor (1), the armature (2) thereof being put into pulsating movements which can be felt upon a touch, an armature coil (3) being supplied with an electric signal from a pulse generator adapted to be started and stopped by means of a signal from a detector coil (5), the inductance of the detector coil (5) being changed when the detector coil (5) is passed in over a ferrite core (6). The armature (2) is assigned a spring, the force thereof being sufficient to bring the armature (2) to the starting position when the external force from the touch ceases.
