Abstract

A device for continuous, uninterrupted patient monitoring includes a portable, self-contained Patient Worn Hub (PWH) device. The PWH is a compact, lightweight patient monitoring device designed to remain with the patient for the duration of care. Parameter measurement devices connect to the PWH. Third party parameter measurement devices connect to the PWH via the use of a connection assembly that translates the information provided by the third party device to the protocol embedded within the PWH. The PWH is able to communicate with a bedside monitor via wired cables or wirelessly. Measured values are shown on external displays and/or on an optional integrated PWH touchscreen display. The PWH includes internal memory for storage of patient data and trends. The PWH optionally includes a docking station for providing operating and battery charging power. The PWH is assigned to each patient and will remain with that patient across multiple departments throughout the care process, thus eliminating the need for re-cabling patients.
