Self-removal problems, in which patients pull out their own medical tubing, remain unresolved while medical tubing introduces more than before. Not only patients can’t receive proper treatment by removing of medical tubing, but also complications such as bleeding and injury from the removal site are considered problematic. It has been adopted as a solution that frequent visits by nurses and monitoring patients, but their burden has become a problem. To reduce this issue, prior studies have examined systems for detecting medical tubing tension, but false positives were caused by patients turning over in bed or being cared for by nurses. Here we show that a prototype flexible sensor that independently detects medical tubing removal and tension. In the evaluation, the sensor detects tension by being pulled, and then applied a certain amount of force, it comes off. In addition, in order to monitor the status of medical tubing in real time, we implemented server transmission of sensor values via BLE (Bluetooth Low Energy), graphing, and LINE notification functions. Our results demonstrate that highly accurate medical tubing condition sensing is possible and reduces the burden on nurses and patients.
