Benefits of technology

This patent describes new technology called non-contact monitoring UWB systems, which can track patients without touching them. These systems use special techniques to match the electrical properties of the device's antennas to those of the patient, making sure the signals are sent and received effectively. One way this happens is by using an impedance transformer like a mat or reclining surface that reduces reflections of the signal back and forth between the antennas. Another technique involves integrating these devices into existing baby beds or monitors, optimizing their placement. Overall, these technologies improve accuracy and efficiency when tracking patients during medical procedures.

Problems solved by technology

The technical problem addressed in this patent is the need for improved non-contact monitoring solutions for young children in critical care settings who require constant surveillance but cannot tolerate traditional electronic equipment without causing harmful effects on their fragile skins.

Embodiment Construction

[0039]The Ultra-Wideband (UWB) monitoring systems described herein may also be referred to as medical radar systems. These systems allow for miniature, extremely low-power medical monitoring systems that are safe and effective. UWB medical radar is an active imaging technology similar in functional concept to ultrasound but is based on electromagnetic, rather than sonic energy. In practice, the systems described herein emit a micro-pulse of electromagnetic energy, typically on the order of one hundred picoseconds in duration, which propagates into the human body. As the energy enters the body, small amounts of the incident energy are reflected back to the device. The reflections are primarily a result of the differences in dielectric properties of the underlying tissues and organs, and can be detected as signals (“reflection signal energy”). The reflection signal energy is then received and processed using signal processing algorithms to extract information on the location, size, an...

Abstract

Ultra wideband patient monitoring systems, and particularly baby monitoring systems, adapted to prevent reflective loss between the antenna and the patient's body. The devices, systems and methods described herein may be used to efficiently couple UWB energy to a patient for patient monitoring. In particular, described herein are impedance transformer pads, mats and the like, upon which a patient may comfortably lie while being monitored via one or more UWB sensors (e.g., antenna); the impedance transformer pads help match the impedance and prevent reflective loss of UWB energy. Also described herein are bassinets, including NICU bassinets and baby monitors.
