Design and implementation of Internet of Things for emergency medical devices based on cloud-edge-device architecture / 生物医学工程学杂志

Internet of Things (IoT) technology plays an important role in smart healthcare. This paper discusses IoT solution for emergency medical devices in hospitals. Based on the cloud-edge-device architecture, different medical devices were connected; Streaming data were parsed, distributed, and computed at the edge nodes; Data were stored, analyzed and visualized in the cloud nodes. The IoT system has been working steadily for nearly 20 months since it run in the emergency department in January 2021. Through preliminary analysis with collected data, IoT performance testing and development of early warning model, the feasibility and reliability of the in-hospital emergency medical devices IoT was verified, which can collect data for a long time on a large scale and support the development and deployment of machine learning models. The paper ends with an outlook on medical device data exchange and wireless transmission in the IoT of emergency medical devices, the connection of emergency equipment inside and outside the hospital, and the next step of analyzing IoT data to develop emergency intelligent IoT applications.

Design and application of digital manometer for air-pocket in manual air-way / 医疗卫生装备

This paper discusses the design of a special digital manometer for air-pocket in manual air-way. Integrated silicon pressure sensor MPX5010 with high precision and sensitivity is adopted in the device. It can not only measure and display air pressure of air-pocket,but also give the alarm for excessive pressure,thus providing a timely and convenient way for clinician to control air-pocket pressure,which ensures the safety and precision for clinic.
