Ohio Patent of the Month – August 2023
Cleveland Medical Devices Inc. (DBA CleveMed), leaders in portable sleep disorders testing, has recently been granted a patent for their sleep diagnostic data acquisition system. This cutting-edge system boasts a multitude of features that cater to a diverse range of medical applications, rendering it a game-changer in the healthcare landscape.
The heart of this innovation lies in its portable, wearable patient interface box. Designed to be securely affixed to a subject, this box performs the remarkable task of measuring and wirelessly transmitting sleep data from multiple sensors. Within its rigid enclosure lies a battery and various electrical components, including a signal processing unit that diligently processes the incoming signals from the attached sensors. These sensors, which can range from accelerometers to pulse oximeters, are strategically positioned to monitor parameters such as blood oxygenation, body position, and even respiratory effort.
What sets CleveMed’s system apart is its integration with a cell phone which operates at frequencies above 2 GHz. The system’s first software, executed by the cell phone, acts as the conduit for the sleep data, wirelessly receiving, re-transmitting, and even processing the information. This data journey continues as the second software, residing on a computer, takes charge of analysis, output, and formatting of the remotely collected sleep data.
One of the standout features of this technology is its ability to mitigate motion artifacts. Thanks to an integrated accelerometer, the system can compensate for the subject’s movements, delivering accurate data even in dynamic scenarios. Additionally, the software filters extract crucial information, enabling the detection of snoring patterns and parameters such as airflow and ventilation rate.
CleveMed’s invention champions customization and adaptability. The system can conduct automatic RF sweeps to detect occupied transmission frequencies, or users can manually select frequencies within designated bands to prevent interference. The innovation not only empowers healthcare professionals but also holds promise for enhancing patient care and diagnosis accuracy.
