- a transmitter unit adapted to attach to the patient so as to be in contact with the patient'"'"'s skin, the transmitter unit including;
attachment means adapted to attach to or around the chest of a patient;
a plurality of sensors mounted to the attachment means to monitor a plurality of patient parameters while in contact with the skin, the monitored parameters including at least the patient'"'"'s skin impedance and electrocardiogram (ECG), the sensors adapted to produce signals related to the parameters being monitored;
a microcontroller to which the sensors are connected, the microcontroller multiplexing the sensors and processing the signals; and
a wireless transmitter to which the microcontroller is connected to transmit a processed signal related to the patient parameters monitored by the sensors; and
a portable receiver unit to receive and process the signal received from said wireless transmitter, the portable receiver unit comprising;
a wireless receiver adapted to receive the signal from the wireless transmitter;
a processor that processes the received signal to calculate sub-components of the patient'"'"'s ECG including at least a heart rate and a QT interval, and wherein the processor determines the hypoglycemic condition of the patient based at least in part on the sub-components, wherein the processor includes a learning neural network processor programmed with a fast learning algorithm; and
display means for displaying data relating to the hypoglycemic condition of the patient.

Abstract
A monitoring device for monitoring the physiological condition of a patient (1) on a continuous basis, which includes a transmitter unit (2) adapted to attach to a patient so as to be in contact with the skin of a patient, a corresponding receiver unit (5). The transmitter unit includes a strap or belt (3) adapted to attach to or around a body part of a patient. A plurality of sensors (E) are mounted to the belt for monitoring a plurality of patient physiological parameters, including at least the patient'"'"'s skin impedance, heart rate and aspects of the heart beat. The sensors are connected to a microcontroller (8) which processes the signals and which is linked to a wireless transmitter (9). A portable receiver unit is adapted to receive and process the signal from the transmitter. The receiver unit includes a display (14) for data relating to the patient and preferably an alarm (15).
