Over 27 million American seniors suffer incontinence, a medical condition where patients lose control of their bladders or bowels. Briefs are worn to capture waste. Soiled briefs must be changed quickly; otherwise, bacteria from urine or feces cause urinary tract infections, the 2nd leading elderly infection, costing $3 Bn annually to treat, and lethal within hours. Prolonged soil exposure also causes pressure sores, dermatitis, and sepsis, costing $65 Bn. Despite these threats, many elderly patients sit soiled for hours. There is a soaring elderly population, and a severe nurse shortage. Worst yet, caregivers currently guess and check whether a patient is soiled, which is uncomfortable, unsanitary, and undignified. Senior Shield dignifies aging with Tenative, an incontinence monitoring pad that alerts caregivers when it is time to change. Tenative is worn outside any brief in a waterproof fabric sleeve. When a urinary or fecal accident occurs, Tenative sends a digital alert to prompt the change routine. Tenative is a medical device pursuing Medicare coverage. Serving nursing homes, home care, hospice, hospitals, skilled nursing, and family caregivers, Senior Shield projects $5.54 Bn TAM based on stated willingness to pay $200-$500 during 140 customer discovery conversations, with working prototypes built.
