Abstract

Claims (37)

1 . A pulse oximeter configured to determine blood oxygen saturation of a tissue site on a finger of a user, said pulse oximeter comprising:

a disposable module comprising:

a sensor comprising a plurality of emitters configured to transmit optical radiation towards the tissue site on the finger of the user and a plurality of detectors configured to detect attenuated light based on an interaction of transmitted optical radiation with the tissue site on the finger of the user;

a first housing secured on a strap, said strap configured to wrap around a wrist of the user, said first housing comprising a first outer surface, a power source, and a first electronic storage device; and

a wire configured to connect the sensor with the first housing; and

a reusable module comprising:

a second housing configured to removably secure to the first housing, said second housing comprising:

a second outer surface, wherein the second outer surface is configured to be flush with the first outer surface when the second housing is secured to the first housing;

a second electronic storage device;

one or more hardware processors configured to:

receive a first set of signals from the plurality of detectors, said first set of signals collected at a first frequency, and process the first set of signals to determine a first blood oxygen saturation value of the user;

determine a first physiological condition of the user based at least in part on the first blood oxygen saturation value;

determine a second frequency based at least in part on the first physiological condition, wherein the second frequency is different from the first frequency;

receive a second set of signals from the plurality of detectors, said second set of signals collected at the second frequency, and process the second set of signals to determine a second blood oxygen saturation value of the user;

automatically determine a first disposable module life expectancy responsive to determining said first blood oxygen saturation value and based on said first frequency and transmit the first disposable module life expectancy to the first housing for storage in the first electronic storage device, wherein the first disposable module life expectancy is based on a life of the power source of the first housing;

automatically determine a second disposable module life expectancy responsive to determining said second blood oxygen saturation value and based on said second frequency and transmit the second disposable module life expectancy to the first housing for storage in the first electronic storage device, wherein the second disposable module life expectancy is based on the life of the power source of the first housing, and wherein the second disposable module life expectancy is different from the first disposable module life expectancy; and

a wireless communication device configured to establish a first wireless communication with a first remote patient monitoring system when the pulse oximeter is within a predetermined distance from the first remote patient monitoring system.

2 . The pulse oximeter of claim 1 , wherein the one or more hardware processors are configured to store data associated with the first physiological condition of the user in the second electronic storage device for a length of time prior to establishing the first wireless communication with the first remote patient monitoring system.

3 . The pulse oximeter of claim 2 , wherein, in determination that the wireless communication device is unable to establish the first wireless communication with the first remote patient monitoring system, the one or more hardware processors are configured to cause the wireless communication device to establish a second wireless communication with a second remote patient monitoring system and transmit the data associated with the first physiological condition of the user to the second remote patient monitoring system.

4 . The pulse oximeter of claim 3 , wherein the one or more hardware processors are further configured to generate and transmit instructions configured to cause the second remote patient monitoring system to establish a third wireless communication with the first remote patient monitoring system and transmit the data associated with the first physiological condition of the user to the first remote patient monitoring system.

5 . The pulse oximeter of claim 2 , wherein the second electronic storage device stores a default length of time, and wherein the second electronic storage device is configured to store data associated with the first physiological condition of the user for the default length of time prior to establishing the first wireless communication with the first remote patient monitoring system.

6 . The pulse oximeter of claim 1 , wherein the first frequency is a default frequency for receiving signals from the plurality of detectors.

7 . The pulse oximeter of claim 1 , wherein the one or more hardware processors are further configured to store the first and/or second set of signals in the second electronic storage device when irregularities are sensed.

8 . The pulse oximeter of claim 7 , wherein the irregularities include at least one of: low blood pressure readings, high blood pressure readings, low respiratory rate readings, high respiratory rate readings, blood oxygen desaturations, irregular heartbeats, consistently low or declining blood oxygen saturation readings, low heart rates, or high heart rates.

9 . The pulse oximeter of claim 1 , wherein the one or more hardware processors are further configured to transmit the processed first and/or second set of signals to a local or a remote electronic storage system when a fourth wireless communication between the wireless communication device and an online server is established.

10 . The pulse oximeter of claim 1 , wherein a fidelity of the processed first and/or second set of signals varies based at least in part on a length of time specified for storing processed data in the second electronic storage device.

11 . The pulse oximeter of claim 1 , wherein a fidelity of the processed first and/or second set of signals varies based at least in part on types of health-related events detected from the processed first and/or second set of signals.

12 . The pulse oximeter of claim 1 , wherein a fidelity of the processed first set of signals varies based at least in part on the first physiological condition of the user.

13 . The pulse oximeter of claim 1 , wherein:

the one or more hardware processors are further configured to retrieve operation data from the sensor when the second housing is removably secured with the first housing; and wherein the one or more hardware processors are further configured to validate the sensor based at least in part on the operation data.

14 . The pulse oximeter of claim 13 , wherein the first electronic storage device stores the operation data.

15 . The pulse oximeter of claim 13 , wherein the validation of the sensor comprises determining whether a sensor type associated with the sensor is compatible with a configuration of the one or more hardware processors.

16 . The pulse oximeter of claim 13 , wherein the operation data comprises at least one of: a power source charge level, a power consumption level, or an expected amount of power usage from data transmission.

17 . The pulse oximeter of claim 1 , wherein the wireless communication device of the second housing is configured to wirelessly transmit said first and/or second blood oxygen saturation values of the user to the first remote patient monitoring system.

18 . The pulse oximeter of claim 1 , wherein the wireless communication device of the second housing is configured to wirelessly transmit said first and/or second disposable module life expectancy to the first remote patient monitoring system.

19 . The pulse oximeter of claim 1 , wherein the reusable module does not include a power source.
