Wireless monitoring system and method with dual mode alarming
First Claim
1. A patient monitoring system, comprising:
- an acquisition device configured to receive physiological data from a patient, the acquisition device comprising;
a control unit configured to detect an alarm condition based on the physiological data from the patient;
a primary transmitter configured to connect to a wireless network and transmit the alarm condition over the wireless network; and
a secondary transmitter configured to transmit the alarm condition using a frequency range other than that used by the primary transmitter; and
a secondary receiver configured to receive transmissions from the secondary transmitter,wherein, upon detecting an alarm condition, the acquisition device transmits the alarm condition via the primary transmitter if the primary transmitter is connected to the primary wireless network and transmits the alarm condition via the secondary transmitter if the primary transmitter is not connected to the primary wireless network.

Abstract
A patient monitoring system and method for reliably communicating alarm conditions detected by an acquisition device that receives physiological data from the patient. The acquisition device includes a control unit that detects alarm conditions based upon the physiological data received from the patient. A primary transmitter and a secondary transmitter are coupled to the control unit and are each capable of transmitting the alarm condition. The primary transmitter is configured to connect to a wireless network and communicate over a first frequency range. The secondary transmitter is configured to transmit over a secondary wireless network using a second frequency range different from the first frequency range. When the primary transmitter is not able to communicate with the primary wireless network, the control unit activates the secondary transmitter to transmit the alarm condition. The secondary transmitter remains active until the primary transmitter reconnects with the primary wireless network.

10. An acquisition device configured to receive physiological data from a patient and for communicating with both a primary wireless network and a secondary wireless network, the acquisition device comprising:
-
a control unit, configured to detect an alarm condition based on the physiological data received from the patient; a primary transmitter configured to connect to the primary wireless network and transmit the alarm condition over the primary wireless network using a first frequency range; and a secondary transmitter configured to transmit the alarm condition over the secondary wireless network using a second frequency range; and wherein the first frequency range and the second frequency range are different frequency ranges; and wherein upon detecting an alarm condition, the acquisition device transmits the alarm condition via the primary transmitter if the primary transmitter is reliably connected to the primary wireless network and transmits the alarm condition via the secondary transmitter only if the primary transmitter is not reliably connected to the primary wireless network. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of transmitting an alarm condition from an acquisition device, comprising:
-
receiving physiological data measured from a patient in the acquisition device; determining the presence of an alarm condition in the acquisition device based on the received physiological data; detecting whether a primary transmitter of the acquisition device is reliably connected to a primary wireless network when the alarm condition is present; utilizing the primary transmitter to transmit the alarm condition using a first frequency range if the primary transmitter is reliably connected to the primary wireless network; and utilizing a secondary transmitter to transmit the alarm condition using a second frequency range if the primary transmitter is not reliably connected to the primary wireless network and an alarm condition is present, wherein the second frequency range is in a different frequency spectrum than the first frequency range. - View Dependent Claims (17, 18, 19)
