System for wireless remote monitoring of alarm events of a medical device and corresponding patient
First Claim
1. A wireless system to monitor the alarm event status of a medical device with an alarm output and alarm output connection selected from a group of medical devices, the system comprising:
- (a) a first transmitter module comprising a connection adapted to connect to the alarm output connection of a medical device selected from the group of medical devices, and further comprising;
(1) a circuit configuration detection algorithm adapted to determine the electrical circuit configuration of the alarm output of the medical device from a plurality of potential configurations;
(2) an alarm status determination algorithm adapted to determine the alarm status of the medical device from a plurality of potential alarm statuses;
(3) a transmitter element with a wireless transmission range and a third algorithm adapted to repeatedly create and wirelessly transmit an alarm status data package corresponding to the alarm status of the medical device;
(b) a wireless receiver module paired to wirelessly communicate with the first transmitter module and further comprising;
(1) a receiving element adapted to receive wireless signals;
(2) a handshake algorithm adapted to determine if a received signal is from the first transmitter module;
(3) a signal processing algorithm adapted to process the received signal if the handshake algorithm determines the signal is from the first transmitter module;
(4) a user interface adapted to communicate the alarm status of the medical device to a user based on the processed received signal.

Abstract
A wireless remote alarm system is described to allow a mobile caregiver or clinician to track the alarm status of a life-critical medical device and patient while the caregiver or clinician is located away from the patient. The system includes automatic recognition of the medical device'"'"'s alarm output circuit for universal compatibility, in order to render the system practical, convenient and reliable to deploy, and protocols for signal reliability, security and power management. The system also includes alarm differentiation protocols to assist the caregiver with alarm prioritization, and remote patient management applications via wider-area network connectivity. The system is especially useful in alternate care and homecare settings, and for monitoring patients using a ventilator.
