Motion monitoring apparatus
First Claim
Patent Images
1. A method of monitoring a patient under medical care, the method comprising steps of:
- providing a sensor arrangement which is arranged to detect motion of a head, limbs and trunk of the patient, and respiratory motion of the patient and produce a motion signal in response to the motion;
monitoring the motion signal;
analysing the motion signal to determine a rate of the motion signal and determine whether the rate of the motion signal is indicative of patient arousal; and
providing an alarm should the monitored motion be indicative of patient arousal;
wherein the patient is a non-human animal which is monitored during recovery from anaesthesia or when under sedation.

Abstract
The present invention relates to a motion monitoring apparatus and method for monitoring a patient under medical care. A sensor arrangement is provided in the form of a pad which the patient lies on. The sensor arrangement provides a signal which can be monitored to observe motion of the patient and provide an alarm should the motion meet certain predetermined conditions. The invention is particularly applicable for monitoring patients under sedation, recovering from anaesthesia, or in intensive care. The device is particularly useful for veterinary patients.

21. A device for monitoring a patient under medical care, the device comprising a sensor arrangement which is arranged to detect motion of a head, limbs and trunk of the patient, and a respiratory motion of the patient and produce a motion signal in response to the motion, and a control means which is arranged to process signals received from the sensor arrangement and analyse the motion signal to determine a rate of the motion signal and determine whether the rate of the motion signal is indicative of patient arousal, and to provide an alarm should the detected motion be indicative of patient arousal;
wherein the device is used with a non-human animal patient, and the control means and a display for providing a visual indication of patient parameters are mounted in a housing which is mounted to a cage for containing the non-human animal patient. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
