What is a urinary-drainage unit primarily used for?

A urinary-drainage unit is primarily designed for the collection of urine. This device plays a crucial role in healthcare settings, particularly for patients who are unable to urinate independently or who are undergoing specific medical procedures. It allows for the safe and sanitary collection of urine, which is vital for monitoring and assessing a patient's condition.

While some devices may aid in measuring urine output, the primary function of a urinary-drainage unit remains focused on the containment and collection of urine, rather than serving as a measurement tool or a means of administering medication. Additionally, filtering impurities in urine is not a function of this unit; instead, such processes generally occur in the kidneys. Understanding the primary function of a urinary-drainage unit helps in efficiently managing patient care and assessing their urinary health.
