What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12581367B2 to RTX A/S for a novel medical system. The patent covers a wireless sensor device designed for transmitting medical data, featuring a self-healing wireless sensor network protocol that allows for automatic master device reassignment if the primary master becomes unavailable. This innovation is intended to enhance the reliability and reduce latency in medical monitoring and intervention devices, with specific mention of its application in Continuous Positive Air Pressure (CPAP) devices.

This patent grant is primarily an intellectual property development and does not impose new regulatory obligations on regulated entities. However, it signifies technological advancement in the health informatics sector. Companies involved in developing or utilizing wireless sensor networks for medical applications, particularly those in the medical device manufacturing and health informatics sectors, should be aware of this granted patent as it may impact future product development and intellectual property strategies.

Abstract

A wireless sensor device for wireless transmission of sensed medical data to a medical monitoring and/or intervention device. The sensor device has a sensor element for sensing a physical parameter related to a body of a living person or animal. A wireless RF transmitter and receiver serves to transmit data packets with the sensed physical parameter, and to also receive data packets, in accordance with a TDMA based network protocol. A processor system controls operation of the wireless RF transmitter and receiver, including that the sensor device can operate as wireless RF synchronization master or slave, and the sensor device can negotiate according to a deterministic negotiation algorithm to appoint one of a plurality of wireless RF devices connected to the TDMA based network as wireless RF synchronization master, if it is detected that no master is available. This allows a self-healing network, since one of a number of slave devices present in the network session can be appointed as a new master, thus even though the master device becomes out of range or is switched off. This provides a reliable and low latency wireless RF network for medical system, e.g. for a Continuous Positive Air Pressure device (CPAP) which can use sensed data from one or more sensor device to control its air blower to provide an appropriate air pressure.
