SATO and Japan’s Mie University Hospital start pilot testing of UHF RFID wristbands

Japan’s Mie University Hospital and the automatic identification technology company SATO are jointly testing SATO’s new ultra-high frequency (UHF) RFID wristband to ensure the safety of its implantable devices for patients, and to determine how the technology can be used to improve employee efficiency and Patient comfort. Hiroyuki Konuma, president of SATO Healthcare, said that the wristbands developed by the company in the past year are now on the market.
Different from SATO’s other HF RFID wristband product, this wristband runs on the UHF frequency band, and the data verification is simpler and more accurate, and it can be completed without touching the card reader.

Although there are currently some UHF RFID wristbands on the market, the fluid in the human body will interfere with its reading, causing unreliable reading. He added that the company has been working on creating a solution to solve this problem, and the wristband with RFID chip now launched can be read well in the presence of liquid. He said that the unique design of the wristband allows it to be read at high speeds in liquid environments.
Konuma said that in the next step, the company will confirm whether 920 MHz (250 mW) RFID transmission will affect pacemakers or other implantable medical devices for patients. To this end, SATO and Mie University Hospital initiated a 2-year clinical study in December 2016.
Konuma said: “The first goal of this cooperation is to determine whether RFID will have an impact on medical equipment. The second goal is to study how to more easily and accurately identify patients and determine the connection between patients and specific drugs. Although the Ministry of Internal Affairs of Japan It has been found that the RFID transmission of the handheld reader will not affect the function of the medical device, but the company is still trying to confirm this result.”
Currently, the hospital provides SATO UHF RFID wristbands for each patient. The hospital organized some patients over the age of 18 to participate in the experiment to confirm whether the implanted device was affected by the wristband.
Mie University serves 20,000 patients every year. In September 2016, the hospital began to use a barcode-based system to identify each patient. However, the hospital prefers to use RFID solutions for reading to prevent reading errors caused by smudged or damaged barcodes.
During the pilot period, each adult patient distributed a SATO UHF RFID wristband, whose ID number was bound to personal information in the hospital software. Each nurse also wears a UHF RFID tag, and the ID number is bound to their information. At the same time, a label is attached to each implantable drug.

A nurse who needs to identify a patient can use a handheld reader to read the patient’s ID number and confirm his or her identity. If the patient needs to inject medicine, the nurse will need to read the ID number of the tag on the patient, medicine and wristband. These readers can accomplish this without having to approach the tag. Then, a record of the event can be created in the hospital’s software.
In addition, some hospitals are also using SATO’s HF RFID wristbands to identify patients and medicines. Konuma said that these wristbands may be replaced with UHF RFID, because UHF technology can not only read tags at a greater distance, but also cheaper than HF tags.
