Monitoring and managing potential infected patients of COVID-19 is still a great challenge for the latest technologies. In this work, IoT based wearable monitoring device is designed to measure various vital signs related to COVID-19. Moreover, the system automatically alerts the concerned medical authorities about any violations of quarantine for potentially infected patients by monitoring their real time GPS data. The wearable sensor placed on the body is connected to edge node in IoT cloud where the data is processed and analyzed to define the state of health condition. The proposed system is implemented with three layered functionalities as wearable IoT sensor layer, cloud layer with Application Peripheral Interface (API) and Android web layer for mobile phones. Each layer has individual functionality, first the data is measured from IoT sensor layer to define the health symptoms. The next layer is used to store the information in the cloud database for preventive measures, alerts, and immediate actions. The Android mobile application layer is responsible for providing notifications and alerts for the potentially infected patient family respondents. The integrated system has both API and mobile application synchronized with each other for predicting and alarming the situation. The design serves as an essential platform that defines the measured readings of COVID-19 symptoms for monitoring, management, and analysis. Furthermore, the work disseminates how digital remote platform as wearable device can be used as a monitoring device to track the health and recovery of a COVID-19 patient.

The paper deals with development of an artificial lung ventilation. The aim of the paper is to present developed ventilator based on bag-valve-mask, which could be used as alternative to mechanical ventilator in critical situations related to COVID-19. At first, we present basic principles of positive pressure ventilation. Subsequently, we introduce a requirements to emergency mechanical ventilator in order to be suitable alternative in hospitals as well as in households. The mechanical and control design are presented in the next section. Finally, we experimentally verify developed ventilator with focus on measured pressure of patient airways. The presented results show a potential of developed ventilator to be used at practical level.

“…Most of the open-source, bag valve-based ventilators use a rigid compressing element. Configurations include the use of a single pivoting, curved element squeezing the bag against a stationary flat element [14], two pivoting flat elements squeezing a simply supported bag [25], one linear reciprocating actuator squeezing the bag against a stationary flat element [13,15,26], two linear, reciprocating actuators squeezing a simply supported bag [27], and two pivoting curved elements compressing a bag supported on a flatbed [28]. Less common is the use of flexible elements.…”

Mechatronic Design and Active Disturbance Rejection Control of a Bag Valve-Based Mechanical Ventilator

This paper presents the mechatronic (mechanical and control system) design of a portable mechanical ventilator to treat patients with a compromised respiratory function. The portable ventilator ensures adequate oxygenation and carbon dioxide clearance while avoiding ventilator-associated lung injury (VALI). Oxygen is delivered through the compression of a bag valve (Ambu bag) using a moving strap. Carbon dioxide is cleared through the control of a pinch valve actuated by a low-torque servo motor. The positive end expiratory pressure (PEEP) is controlled by an adjustable mechanical valve the system. An Arduino Mega microcontroller board is used in this prototype to control the respiratory variables. All mechanical components as well as sensors, actuators and control hardware are of common use in robotics and are very inexpensive. The total cost of the prototype build in this work is about $425 U.S. dollars. The design is meant to be replicated and utilized in emergency conditions that involve an overwhelming number of cases, such as COVID-19 treatment, in places with no access to commercial MV technologies. In order to account for variations in the prototype as built, the software developed for this portable MV applies an active disturbance rejection control strategy (ADRC). This control strategy is presented as a universal control structure for any mechanical ventilator able to supply air flow with controlled pressure and volume.
