Fujitsu and Wakayama Medical University launch joint trials of millimeter wave sensor to detect falls in elderly patients

TOKYO, November 21, 2022 – (JCN Newswire) – – Fujitsu and Wakayama Medical University today announced the start of joint trials of technology to help nurses and caregivers visually monitor patients in privacy-sensitive settings, including hospital rooms and nursing facilities. The technology uses Fujitsu’s technique to accurately estimate human body postures using a millimeter wave sensor and Fujitsu’s “Actlyzer”(1) artificial intelligence technology for analysis complex human behaviors. Using a millimeter wave sensor to collect point cloud data and no cameras, Fujitsu’s technology will help help nurses and caregivers monitor patients and achieve faster response to emergency situations, including falls and possible serious injuries, while ensuring patient confidentiality.

Fujitsu will analyze the data obtained from the trials and refine its technology based on the analysis results evaluated by Wakayama Medical UniversityPress on Wakayama Medical University knowledge from the medical field.

Based on these results, both parties aim to offer millimeter wave sensor service for privacy-conscious monitoring to hospitals and nursing facilities in fiscal year 2023. Ultimately, the Both parties hope to help enrich people’s lives by achieving an environment in which older people can enjoy greater independence and privacy without sacrificing their personal safety.

Technology to help reduce the risk of serious injury in older adults

In fiscal year 2021, the Japan Hospital Association(2) counted a total of 290 falls per month in 18 hospitals in Japan. While these figures highlight the risk of falls and injuries to older people and the need for patient monitoring, surveillance technologies using cameras remain difficult to install in highly private spaces such as hospitals and homes. of retirement.

To meet this challenge, Fujitsu and Wakayama Medical University began joint trials in real seniors’ facilities to help reduce the risk of serious injuries such as broken bones by helping nurses and caregivers monitor patients and respond more quickly to emergency situations while ensuring patient confidentiality.

About Joint Demo Trials

1. Trial period:

November 21, 2022 – March 31, 2024

2. Overview:

(1) Demonstration of monitoring technology using millimeter wave sensor

– Demonstration trials of Fujitsu’s technology to accurately estimate human body postures from point cloud data using a millimeter wave sensor (announced in July 2022) in combination with Fujitsu’s “Actlyzer” AI technology for the analysis of complex human behaviors to verify that the technologies are able to detect human body movements such as falls while maintaining patient privacy

(2) Measurement data in trials with elderly people

– Demonstration trials in hospitals and nursing homes with elderly patients and people requiring nursing care; collecting point cloud data on patients’ postures using a millimeter wave sensor installed inside the facilities and using Fujitsu’s monitoring technology to detect movements that could lead to falls

– Assess whether the system is able to accurately detect patient postures by comparing test results with logs from motion sensors installed around patient beds(3) and data from cameras(4) installed for posture testing. demonstration

(3) Development of a privacy-conscious monitoring service

– Fujitsu will analyze specific body movements that lead to falls based on point cloud data obtained with a millimeter wave sensor. Point cloud data does not include any personal patient information and is therefore also suitable for highly private spaces.

– Wakayama Medical University evaluate Fujitsu’s technology based on the results of Fujitsu’s analysis based on its knowledge in the medical field; Based on the evaluation results, Fujitsu will further improve its monitoring technology with the aim of offering privacy-conscious monitoring technology for hospitals and nursing facilities in Japan by the end of fiscal year 2023

3. Roles and Responsibilities:

Fujitsu

Provision of monitoring technologies, data collection and analysis, improvements based on technical assessment

Wakayama Medical University

technical assessment from a medical practice perspective and direction of technical improvement

(1) Actlyzer Behavioral Analysis Technology:

Technology marketed as Fujitsu AI technology for video-based behavioral analysis solution “FUJITSU Technical Computing Solution GREENAGES Citywide Surveillance” to recognize human actions.

(2) Japan Hospital Association :

Headquarters: Chiyoda-ku, Tokyo; Head: Yuji Inokuchi. Report on the number of patient falls in participating hospitals in fiscal year 2021: www.ajha.or.jp/hms/qualityhealthcare/indicator/42/ (in Japanese)

(3) Motion sensor:

A device to prevent falls and uncontrolled walking of patients in hospitals and institutions. There are two types of sensors: one that uses infrared light to detect a person’s movement, and one that uses a mat sensor or bed sensor to detect a person’s movement.

(4) Cameras are only installed during demonstration tests. The technology itself does not use cameras.
