Abstract

Claims (37)

1 . A portable physiological monitoring system comprising:

an optical sensor configured to output one or more first signals responsive to light from a light source attenuated by tissue of a user at a measurement site, said one or more signals indicative of an oxygen saturation (“SpO2”) of said tissue;

a mobile computing device configured to communicate over a cellular network; and

a processing board in data communication with the optical sensor and the mobile computing device, wherein the processing board is configured to:

receive said one or more first signals from the optical sensor;

receive one or more second signals indicative of an activity level of the user, wherein the one or more second signals are generated by a physiological sensor or are input by the user or a care giver;

process said one or more first signals to generate one or more SpO2 measurement values;

process said one or more second signals to generate an indicator of the activity level;

adjust an alarm setting on the mobile computing device for the SpO2 measurement values based at least in part on the indicator of the activity level; and

wirelessly transmit the one or more SpO2 measurement values to the mobile computing device,

wherein the mobile computing device is further configured to trigger, based on the SpO2 measurement exceeding an alarm condition of the alarm setting, a notification to a care provider device via the cellular network;

wherein the processing of said one or more first signals to generate said one or more SpO2 measurement values is performed only on the processing board, thereby freeing up memory available to the mobile computing device.

2 . The portable physiological monitoring system of claim 1 , wherein one or more hardware processors of the mobile computing device are configured to execute an application, the application configured to execute commands to:

display a representation of the one or more SpO2 measurement values generated by the processing board.

3 . The portable physiological monitoring system of claim 1 , further comprising a cable configured to couple the optical sensor to the processing board.

4 . The portable physiological monitoring system of claim 1 , wherein the optical sensor is configured to secure to a finger of the user.

5 . The portable physiological monitoring system of claim 4 , wherein the optical sensor is configured to wrap around the finger of the user.

6 . The portable physiological monitoring system of claim 1 , wherein at least a portion of the portable physiological monitoring system is disposable.

7 . The portable physiological monitoring system of claim 5 , wherein the optical sensor is disposable.

8 . The portable physiological monitoring system of claim 1 , wherein the mobile computing device comprises a smartphone or wearable device.

9 . The portable physiological monitoring system of claim 1 , wherein the processing board is surrounded by an enclosure.

10 . The portable physiological monitoring system of claim 1 , wherein the mobile computing device is configured to output one or more alarms associated with SpO2 measurement values that are above or below threshold SpO2 measurement values.

11 . The portable physiological monitoring system of claim 1 , wherein the mobile computing device is configured to output an alert, via a network to a designated physician or other care provider, regarding abnormal SpO2 readings.

12 . A method of monitoring one or more physiological parameters of a patient, the method comprising:

monitoring, using a portable physiological sensor system, a physiological parameter associated with a tissue site of the patient, wherein the portable physiological sensor system comprises: a sensor configured to output one or more signals responsive to the physiological parameter of the patient, and a processing board in wireless communication with a mobile device, the processing board configured to generate patient data comprising one or more measurement values based on the one or more signals;

transmitting, using the mobile device, patient data to a cellular or satellite network;

monitoring an activity level of the patient;

adjusting alarm settings for the patient data based at least in part on the activity level; and

outputting, from the mobile device and based on the patient data exceeding an alarm condition of the alarm settings, a notification to a care provider device via the cellular or satellite network.

13 . The method of claim 12 , wherein the sensor comprises an optical sensor and the measurement values comprise SpO2 values.

14 . The method of claim 13 , wherein the optical sensor is configured to secure to a finger of the patient.

15 . The method of claim 14 , wherein the optical sensor is configured to wrap around the finger of the patient.

16 . The method of claim 13 , wherein the alarm condition comprises threshold SpO2 measurement values.

17 . The method of claim 12 , wherein at least a portion of the portable physiological sensor system is disposable.

18 . The method of claim 12 , wherein the sensor comprises a temperature sensor and the physiological parameter comprises a temperature.

19 . The method of claim 18 , wherein the alarm condition comprises threshold temperature measurement values.

20 . The method of claim 12 , wherein the transmitting using the mobile device comprises transmitting using a smartphone; and wherein the processing board is in communication with the smartphone.
