Abstract

A remote patient monitoring system provides patient physiological data and alerts/alarms from a main patient monitor to a remote patient monitor worn by a medical professional. The medical professional is alerted as to physiological data of the monitored patient, and provided alerts or alarms when predetermined levels are reached. The medical professional is able to reset the alert or alarms at the remote patient monitor.

Claims

1. A patient monitoring system, comprising:

a main patient monitor configured to receive and collect one or more patient physiological parameters of a patient, and to provide an alarm in response, at least in part, to an alarm trigger, the alarm trigger including a determination that at least one of the collected patient physiological parameters has reached a predetermined value; and

a remote patient monitor having a band and an alarm reset configured to terminate the alarm, the remote patient monitor being configured to be worn by a caregiver, and further configured to receive a signal from the main patient monitor in response to the alarm and to transmit an indication about the alarm trigger, the indication comprising one or more of a notification that the patient is being attended to, a request by the caregiver for additional help, or a message about resolution of the alarm trigger.

2. The patient monitoring system of claim 1, wherein the main patient monitor is further configured to transmit at least one of:

the collected patient physiological parameter data, patient identification, location identification, device data concerning the remote patient monitor, device data concerning one or more medical probes or delivery devices connected to the main patient monitor, and caregiver messages.

3. The patient monitoring system of claim 1, wherein the remote patient monitor is further configured to display at least one of:

the collected patient physiological parameter received from the main patient monitor, patient identification, location identification, device data concerning the remote patient monitor, device data concerning one or more medical probes or delivery devices connected to the main patient monitor, and caregiver messages.

4. The patient monitoring system of claim 1, wherein patient physiological parameter data includes at least one of:

a heart rate, a blood pressure, an oxygen saturation, an end-tidal CO2, or a respiration rate.

5. The patient monitoring system of claim 1, wherein the band is attachable to the caregiver'"'"'s arm, wrist, neck, belt, or waist.

6. The patient monitoring system of claim 1, wherein the main patient monitor and remote patient monitor are coupled wirelessly through one or more networks.

7. The patient monitoring system of claim 1, wherein the remote patient monitor is further configured to, in response to the signal from the main patient monitor, commence an action selected from a group consisting of vibration output, visual output, and auditory output.

8. The patient monitoring system of claim 1, wherein the alarm trigger comprises an overall urgency alarm.

9. The patient monitoring system of claim 1, wherein the main patient monitor is a plurality of different main patient monitors, and wherein each main patient monitor of the plurality of different main patient monitors is configured to monitor an individual patient and provide alarm signals to one or more of the remote patient monitors.

19. The patient monitoring system of claim 6, wherein the one or more networks is as a cloud-based network.

20. The patient monitoring system of claim 7, wherein the remote monitor is configured to vary an intensity of the commenced action, the intensity of the commenced action being indicative of a risk to the patient.

10. A method that facilitates remotely monitoring a patient using a remote patient monitor configured to be worn by a user, the method comprising:

receiving patient physiological parameter data at the remote patient monitor;

displaying the patient physiological parameter data on the remote patient monitor;

initiating a vibration alarm at the remote patient monitor in response to a received alarm trigger;

receiving at the remote patient monitor an alarm reset signal from the user;

receiving an alarm reset input at the remote patient monitor to terminate the alarm; and

transmitting an indication about the alarm trigger, the indication comprising one or more of a notification that the patient is being attended to, a request by the user for additional help, or a message about resolution of the alarm trigger.

11. The method of claim 10, wherein the alarm trigger comprises one or more of a general urgency alarm or an indication that a patient physiological parameter reached a predetermined value.

12. The method of claim 11, further comprising escalating an intensity of the vibration alarm, the intensity being indicative of a risk to a patient.

13. The method of claim 10, wherein receiving patient physiological parameter data includes receiving at least one of:

a heart rate, a blood pressure, an oxygen saturation, an end-tidal CO2, or a respiration rate.

14. The method of claim 10, wherein receiving patient physiological parameter data includes receiving patient physiological parameter data from more than one patient.

15. An article comprising:

a non-transitory storage medium, the storage medium having instructions stored thereon, wherein, when the instructions are executed by a remote patient monitor having a band, the remote patient monitor performs operations comprising;

receiving patient physiological parameter data at a wireless module of the remote patient monitor;

displaying the patient physiological parameter data;

initiating a vibration alarm at the remote patient monitor in response to a received alarm trigger;

stopping the vibration alarm in response to an alarm reset input at the remote patient monitor; and

transmitting an indication about the alarm trigger, the indication comprising one or more of a notification that the patient is being attended to, a request by the user for additional help, or a message about resolution of the alarm trigger.

16. The article of claim 15, wherein the alarm trigger comprises one or more of a general urgency alarm or an indication that a patient physiological parameter reached a predetermined value.

17. The article of claim 15, wherein the received patient physiological parameter data includes one or more of:

a heart rate, a blood pressure, an oxygen saturation, an end-tidal CO2, or a respiration rate.

18. The article of claim 15, wherein the received patient physiological parameter data includes physiological parameter data from more than one patient.
