Nagoya University Hospital, Japan, announced in early January 2018 that it will launch a pilot program in February for the deployment of robots designed to deliver medicine and test samples in hospitals.
The purpose of the devices is to deal with labor shortages but also reduce the workload of nurses, doctors and other staff members as it allows them to focus more on their core tasks in order to spend more time caring for patients and less time retrieving or transporting medical materials.
The robot follows the instructions of the staff via a digital tablet
During the year-long trial, four robots will work at the Japanese hospital, shuttling between the surgical intensive care unit, the hospital pharmacy and the laboratory to deliver intravenous fluids, test samples and other materials to healthcare professionals who need it.
Registered workers, including nurses and pharmacists, can call a robot and indicate its destination via a tablet. The tool then automatically delivers the materials according to the instructions provided.
The devices will be operated on night shifts, when medical teams are reduced
The four robots will be mobilized between 5 pm and 8 am, when fewer employees are working.
Smart tools
The robots will travel referring to hospital floor plans and relying on radar devices and cameras with a 360-degree field of view. They can use elevators and automatically go to a charging station when they need it.
If a person gets in their way, the robot have two options: dodging him/her or airing the following message: « Excuse me, please let me pass. »
Robots can carry up to 30 kg of material
Each device is 125 centimeters tall, 50 centimeters wide and 63 centimeters deep. It can travel up to 3.6 kph. Shaped like a refrigerator, the machine has a capacity of 90 liters and can carry up to 30 kilograms of medicines and samples.
If the outcomes are good, hospital officials could extend their use to other departments.
A project inspired by the automotive industry
The solution was developed jointly by Nagoya University and Toyota Industries Corp., an affiliate of Toyota Motor Corp., based on the technology designed for self-driving cars.
Similar autonomous transfer robots are already used at auto plants and in other sectors, but the device has rarely been introduced to hospitals or other medical facilities in Japan, officials said (source: Asahi.com).
The Nagoya University Hospital project aims to take advantage of robot technologies developed in the manufacturing sector to improve the efficiency and quality of healthcare delivery.
