A medical device for early diagnosis of urinary tract infections in catheterized patients


30% of Health Care Associated Infections (HCAIs) are Urinary Tract Infections (UTIs) caused by indwelling urinary catheters. UTIs worsen the health status of already debilitated patients, increasing both the length of their hospital stay, and their risk of mortality. Furthermore, cost of treatment and care time required by health professionals increases when UTIs take hold.


  • To develop TimeUp, a small device that is placed between the catheter and the urine bag, constantly monitoring patient’s urine for possible infections. This 24/7 control eliminates the need to await the healthcare professional’s decision to perform an analysis.

Problem to Solve

Statistically, 1 in 10 patients admitted in a hospital will suffer from a health care associated infection (HCAI). Urinary Tract Infections (UTI) associated with the use of urinary catheters represent 30% of the total HCAI, costing €84 million per year in Portugal alone. Besides the economic impact, these infections are responsible for worsening the health status of patients, and increasing length of hospital stay, mortality rates, and cost of treatment.


TimeUp is a technology that allows health professionals to be informed of an early stage of UTI. The device, which is placed between the urinary catheter and the urine collection bag, constantly monitors urine. The colour of the device changes when bacteria is detected, alerting the healthcare team when safety is compromised.
