STUDY: Tele-COVID – Remote Patient Monitoring for COVID-19

Empower your medical team and your patients with remote patient monitoring.

Within the framework of a first-in-class study in Munich, cosinuss° provides the pioneering biosensor technology to monitor low and medium risk patients of COVID-19, who are in home isolation. The clinical study is initiated and led by Prof. Dr. Med. Georg Schmidt, head of the Biosignal Analysis Working Group, Klinikum rechts der Isar, Technical University of Munich. 

With the monitoring system, cosinuss° provides  a highly cost-effective, easy to handle and fast to configure extended workbench for healthcare centers. It consists of an in-ear wearable sensor (cosinuss° Two) a data-gateway (cosinuss° LabApp or cosinuss° LabGateway) and a server database (cosinuss° LabServer). 

University Hospital in Munich is testing cosinuss° in-ear senosrs for fighting Covid-19.

The in-ear sensor collects key physiological vital parameters from the patient in isolation, and transmits the data to the cosinuss° server, where early warning algorithms calculate a composite score in real-time. Health professionals access all the vital patient information via a simple web interface. The cosinuss° solution supports health professionals in determining the urgency of the respective health situation and the necessity of hospital admission.

Key physiological parameters that are monitored include:

• Core Body Temperature
• Heart Rate
• Blood Oxygen Saturation 
• Respiration Rate

In this ongoing clinical study, the goal is to make the pandemic outbreak more manageable and to keep up a functioning healthcare system by:

• Relieving hospital overload, increasing efficiency
• Lowering the risk of infection for health workers and other inpatients
• Providing timely and effective healthcare intervention for the affected people
• Continuously telemonitoring people in home isolation
• Providing accurate data basis for early clinical studies

Low to middle risk patients are equipped with a wearable in-ear sensor and a cosinuss° Gateway. The wearable sensor is measuring vital signs data from inside the ear canal and is transmitting collected values via Bluetooth 4.0 to the data-gateway. The data-gateway can be a mobile app (cosinuss° LabApp) or a stand-alone device (cosinuss° LabGateway) which is capturing and storing the transferred data. From here the patient’s data-gateway transmits the collected data in real-time or at a specified time to the cosinuss° LabServer.

In the LabServer, the collected vital data is processed in real-time, through advanced algorithms and analytics, in order to determine the early warning scores. Via the cosinuss° WebInterface, health professionals are able to visualize and access the vital information per patient. The researchers can access the anonymised health data in the LabServer with a standard interface (e.g. REST API).

Visualization of the remote patient monitoring dataflow from the cosinuss° wearable sensor, to the data-gateway and to the cloud server.

cosinuss° wearable sensors detect, analyze and transmit information concerning physiological body signals such as vital signs, and ambient data which allow immediate biofeedback to the wearer and/or to remote operators in healthcare.

The wearable in-ear sensor for monitoring vital signs remotely: cosinuss° Two

There are two different data-gateway solutions: either for closed, stationary settings with a preference for minimum user-device interaction (e.g. cosinuss° LabGateway) or for mobile remote settings, with a high user-device interaction (e.g. cosinuss LabApp). Additionally our advanced algorithms successfully reduce the workload of network computing.

The LabGateway is a device that is collecting and transferring the collected data to the LabServer. It can also act as a control element by waking up the wearable sensor at predefined times, reducing the level of user interaction required. An optional SIM card integration makes it a truly stand-alone gateway solution.

The stand-alone gateway, cosinuss° LabGateway, requires minimum user interaction.

The cosinuss° LabApp is a gateway application running on a mobile phone or a tablet. It receives the data from the wearable sensor and transfers it to the cosinuss° LabServer, either in real-time or periodically. User-device interactions and a communication interface can be individually enabled.

The cosinuss° LabApp turns a smartphone into a mobile remote monitoring gateway.

The server is an accessible database in the cloud.

The cosinuss° LabServer combines a cloud database and a web interface empowering health centers with accurate reliable data and remote patient management capabilities. The additional computing power of the server allows a real-time data analysis. Advanced algorithms calculate additional key physiological parameters, such as:

• Respiration Rate
• Heart Rate Variability

The LabServer is available as a ‘Software as a Service’ (SaaS).

Pseudonymized vital signs data received from the patient’s home can be monitored in real-time by healthcare centers using the cosinuss° WebInterface.

The cosinuss° solute for remote monitoring of COVID-19 patients can be set up in a few simple steps:

1. Healthcare centers receive an URL as well as a username and password. They open the URL and enter username and password to access all monitored vital data and information. In this way, they can see the real-time measurements.
2. Patients receive a wearable in-ear sensor and a data-gateway (LabApp or LabGateway). The wearable sensor can be easily placed in the ear.
3. If the LabGateway solution is chosen, the device has to be solely plugged into a socket. If the LabApp is used, patients need to first install the app and then connect the wearable sensor with their smartphone via Bluetooth.

All personal identifying information and medical health data on the cosinuss° LabServer are pseudonymized. Only authorized persons have access to the data.

The data transfer is encrypted and has repeatedly passed
