How it works;

A tri-coloured LED is situated at the top of the location spike, which is located in the center of the reservoir is the main alarm.

The sensor based at the back of the reservoir checks the water level every 20 seconds. This allows the base to 'know' how much water has been drank over time. It can compare this with how much water the patient should be drinking and calculate if they need reminding.

If the patient is not drinking at a sufficient rate it starts to pulse gently light blue. Pouring a glass of water is likely to turn the flashing off.

If the patient continues not to drink for a further 2 hours, the light pulses green at a slightly faster rate. This allow carers to identify which patients they need to encourage drinking.

After 6 hours with not enough fluid consumption the light pulses bright red allowing carers identify potential problems.

After 8 hours, if still no water is consumed the device flashes bright red. There must be a problem here. The carers can quickly put the patient of intravenous drips or take other measures to prevent serious problems from occurring.

The patient should see the device to be as important as their drips or medication, and as something which will help them to recover faster. For the carer, it should be seen as a helping hand in combating dehydration and as an indicator of how much water has been consumed.
