In the medical field, due to rapid progress of medical technology and a transition to home medical care, promotion of ICT for medical care is an important way of improving the safety of medical devices. Now in the development stage, it will become a very important factor of risk management in future medical treatment.

From a survey of ICT use related to home medical devices and attitudes regarding ICT in the medical field, we investigated whether the safety of medical equipment could be improved by ICT.

Based on the results of survey analysis, it emerged that introduction of ICT into the medical field leads to better information-sharing and use of information regarding medical accidents and incidents, which is expected to contribute to improving medical safety and reducing the risk of medical accidents. Moreover, it is important to promote the safety of information systems and their operation by "risk management of medical equipment" and "improvement of ICT literacy", against factors causing a gap in ICT progress. This will allow safe and reliable medical treatment, and lead to further progress in ICT medical care.

Removal of intravenous infusion lines and puncture needles from blood vessels disables administration of the necessary amount of intravenous fluids for the patient and thus carries the risk of complications such as bleeding from the blood vessel. The objective of this study is to build a system to sense the removal (movement/shifting) of an intravenous line when it is pulled using a reed switch; to quantitatively and objectively monitor and record the fixation and retention of an intravenous line; and to conduct a basic assessment of the system. The system comprises a reed switch, a micro-controller, 2-color LEDs, a piezoelectric speaker, and neodymium magnets. An experiment to test reed switch reaction has showed that the magnet is de-energized when separated from the end of the reed switch by 10mm or more. In addition, a test for reed switch operation has confirmed that the system (red LED illuminating and alarm sounding) operated when the intravenous line was removed (shifted). The system can be leveraged in medical facilities and in the home and can contribute to the safety of various types of patients, such as the elderly and with cognitive impairment.
