An active infiltration of information technology in the healthcare sector has led to a fundamental change in people's quality of life. In this regard, the security and safety problems of this technology using increase rapidly. This paper touches upon the issue of the healthcare Internet of Things (IoT) infrastructure failures of components and complete system. The purpose of the paper is to develop and research an availability model of a healthcare IoT system regarding failures of components. A detailed analysis of an architecture of healthcare IoT infrastructure is given. The main causes of the healthcare IoT based system failures are considered. Much attention is given to developing and research of a Markov model of a healthcare IoT system considering failures of components. Some essential high-level requirements that such system must meet are presented. The analysis of obtained simulation results showed the rates that have the greatest influence on the availability function of the healthcare IoT system.
