System for monitoring a number of different parameters of a patient in a bed
First Claim
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.

Abstract
In order to provide a simple and reliable monitoring technique for a number of different parameters of a patient in a bed (2), a system (1) is provided, said system (1) comprising: at least one first sensor device (25) adapted to measure a first force component acting in a first direction (12), said first force component corresponding to a first parameter of the patient, at least one second sensor device (36) adapted to measure a second force component acting in a second direction (13, 14), said second force component corresponding to a second parameter of the patient, and a data device (16) adapted to acquire the measured data from the at least one first sensor device (25) and the at least one second sensor device (36) and to process those data in order to provide information about the number of parameters of the patient.

8. A system for monitoring at least respiration and heart rate parameters of a patient in a bed, the system comprising:
-
a base frame; sensor units mounted to the base frame, each sensor unit including; a first sensor device which measures a first force component acting in a first direction on a slide which is movable in a second direction orthogonal to the first direction, the first sensor generating a first signal indicative of the first force component; a second sensor device which measures a second force component acting in the second direction on the slide and generates a second signal indicative of the second force component; a patient support mounted to and supported by the sensor units and wherein each sensor unit enables relative movement between the base frame and the patient support via the slide; and a data device which receives the first and second signals from the sensor units and processes the first and second signals to provide information about the respiration and heart rate parameters of the patient. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of monitoring respiration and heart rate parameters of a patient in a bed, the method comprising:
-
supporting a plurality of sensor units adjacent an upper end of a base frame; supporting a patient support which is adapted to support a mattress on the plurality of sensor units; with each sensor unit, measuring; at least one first force component acting in a first direction on a slide which is movable relative to one of the base frame and patient support in a second direction and generating first force component data indicative of the measured at least one first force component with a first force sensing device; at least one second force component acting on the slide in the second direction and generating second force component data indicative of the measured at least one second force component with a second sensor device, said second direction being different from the first direction; processing the first force component data and the second force component data to determine the respiration and heart rate parameters of the patient; and displaying the determined respiration and heart rate parameters on a display device. - View Dependent Claims (16, 17)
