Currently, hospitals are using stand alone multi parameter monitoring system for each bed, which are bulkier and expensive to use. The prototype of stable wireless multi-patient monitor with ambient light compensation is very easy to use, hand held and wireless device with high accuracy. At present SpO2 and Heart rate are the parameters monitoring considered for proof of concept demonstration and can be extended to other parameters. The idea has been patented (patent number: 201621007087) and prototype developed is under testing phase. This gives high accurate and stable results because it compensates ambient light influencing calculations which usually disrupt the readings.
