1. A system for monitoring a plurality of physiological parameters of a patient in a bed, the system comprising:

  • a base frame;

    a patient support;

    a plurality of sensor units mounted between the base frame and the patient support to support the patient support, each of the sensor units including;

    a first sensor device which measures a first force component in a first direction, the first sensor device being attached to one of the patient support and the base frame;

    a rail mounted to the other of the patient support and the base frame;

    a slide which is supported on the rail and movable relative to the rail, wherein the first sensor device is in contact with the slide;

    a second sensor device attached adjacent the rail to interact with the slide to measure a second force component in a second direction, the second direction being different from the first direction; and

    a data device which receives measured force component data from the sensor units and processes the force component data to provide information about the plurality of physiological parameters of the patient.
