AI Technical Summary

Technical Problem

Existing medical catheter and dressing removal detection systems suffer from false alarms due to unrelated contact and privacy concerns from image-based monitoring, and fail to accurately predict and detect the removal of medical devices in patients with consciousness disorders.

Method used

A contact motion judgment module that uses a contact detection sensor to acquire contact signals, analyze signal intervals and patterns, and output specific action signals for medical catheter or dressing removal, utilizing a bio-contact detection device with electrodes on a flexible substrate to detect contact and prevent false alarms.

Benefits of technology

Accurately predicts and detects the removal of medical devices with reduced false alarms by analyzing contact signal intervals, improving patient monitoring and reducing unnecessary notifications.

Abstract

To provide a living body contact detection sensor capable of detecting that a patient himself or herself has pulled out a medical catheter and has removed a bandage, a covering material, a skin bonding tape, etc. beforehand, and to provide a living body contact detection device using the living body contact detection sensor.SOLUTION: A contact operation determination module for executing prediction determination of a specific operation in a wearer includes: a contact signal acquisition part for acquiring a contact signal from a contact detection sensor for detecting contact of the wearer; an operation determination part for determining an operation of the wearer on the basis of an interval, pattern and / or output of the contact signal acquired by the contact signal acquisition part; and an operation signal output part for outputting the operation signal when the result in the operation determination part is determined to be a specific operation.SELECTED DRAWING: Figure 3
