KATALIS, an Automatic Urinary Catheter that Reduce the Burden of Health Workers in the Pandemic

During the current pandemic, the burden of health workers in Indonesia has definitely increased significantly, especially in the intensive care unit/ICU where critical patients who need various life support devices are placed.

One of these life support devices is a urinary catheter, a device that helps patients excrete urine.

With the presence of a urinary catheter, health workers can early detect diseases that may occur in patients.

However, unfortunately limited ICU health personnel must monitor urinary catheters in real-time.

With this background, five Universitas Brawijaya students who are members of the Student Creativity Program- Creative Initiative (PKM-KC) team consist of Maghfira Rahma Azizah (FK), Indira Swastika Utama (FK), Aliifah Hanantika (FK), Muhammad Rizky Akbar (FT). ), and Muhammad Fawwaz Islami (Vocational) under the guidance of Dr. Yulian Wiji Utami, S.Kp., M.Kes, created an IoT-integrated urinary catheter for ICU patients in hospitals.

“Monitoring urine output by health workers on patients during the pandemic is very inefficient. With the creation of this automatic urinary evaluation catheter, it is hoped that the workload of health workers can be reduced so that they can allocate their time and energy in doing other things with higher urgency,” said one of the team members, Maghfira.


KATALIS has advantages over other advanced catheters, in which it has three sensors to monitor changes in color, volume, and pH in the patient’s urine in real-time.

With KATALIS, health workers can monitor changes in urine in patients without having to approach patients one by one directly as is usually done.

KATALIS is connected to an IoT application that is equipped with notifications if there are conditions that require health workers to follow up on changes in the patient’s urine directly.

In addition, in the KATALIS application there are patient profile features that are the responsibility of the health worker concerned, including medical records, sensor evaluation data result, and sensor evaluation data graphs that are presented hourly.

KATALIS uses three sensors installed to support its function, namely the TCS3200 color sensor, the DF Robot V1.1 pH meter sensor, and the water-level sensor. The sensor is activated by connecting the adapter to electricity source.

The application of an automatic evaluation urinary catheter is the same as a urinary catheter in general, so that health workers have no difficulty in using this catheter.

Another difference between KATALIS and conventional urinary catheters is the use of acrylic instead of disposable urine bags.

The purpose of using acrylic is to save on the use of plastic used for the production of disposable urine bags.

To dispose urine, the user does not need to disassemble the acrylic block, but simply by opening the hole on the side of the block, the user can empty the acrylic box where urine is stored.

KATALIS has succeeded in obtaining research funding from the Ministry of Education, Culture, Research, and Technology of the Republic of Indonesia in the Student Creativity Week in the field of Copyrights in 2021 and will fight for the XXXIV National Student Scientific Week (PIMNAS) 2021 in October.
