Smart Coaster Fights Hospital Dehydration Epidemic

A smart hydration coaster has been developed to address the critical issue of dehydration among hospital patients, an often-under-recognized problem referred to as a "hidden epidemic." This innovative device employs a load cell sensor to monitor cup weight; if no drinking is detected within 60 minutes, an LED ring illuminates as a gentle reminder. The system is designed for ease of use and infection control, featuring a waterproof construction with no external ports and wireless charging.

Dehydration can significantly extend hospital stays, diminish patient well-being, and burden healthcare staff. This problem is estimated to cost the NHS between £500 million and £1 billion annually. The hydration coaster, made from recycled materials, is priced affordably at £34.99 for NHS use. By potentially reducing a patient's hospital stay by even one day, the savings could cover the cost of over twenty coasters, highlighting its dual benefit of enhanced patient care and financial efficiency.

The coaster operates during waking hours, typically from 7 am to 10 pm, ensuring patients are not disturbed at night. A single charge lasts up to two weeks. Visual indicators alert staff to faults, low battery, or if a cup is not replaced. With approximately 140,000 NHS beds in England, even minor improvements in hydration can lead to quicker recoveries, earlier discharges, and substantial cost reductions, while also improving patient happiness and alertness.
