Abstract
A device includes a glucose monitor comprising at least one sensor electrode configured to sense signals indicative of interstitial glucose level of a patient. The device also includes a memory and one or more processors implemented in circuitry and in communication with the memory. The one or more processors are configured to cause delivery of a cleaning electrical current to the at least one sensor electrode. The cleaning electrical current is one or more electrochemical cleaning pulses configured to at least partially remove, in vivo and from the sensor electrode, excipients associated with the delivery of a fluid that includes insulin.
Claims20
A device comprising:
- a glucose monitor comprising at least one sensor electrode configured to sense signals indicative of interstitial glucose level of a patient;
- a memory;
- and
- one or more processors implemented in circuitry and in communication with the memory, the one or more processors configured to:
- cause delivery of a cleaning electrical current to the at least one sensor electrode, the cleaning electrical current being one or more electrochemical cleaning pulses configured to at least partially remove, in vivo and from the sensor electrode, excipients associated with the delivery of a fluid that includes insulin.
A method comprising:
- determining, via one or processors implemented in circuitry and in communication with a memory of a device comprising a glucose monitor, that a cleaning electrical current should be delivered to at least one sensor electrode of the glucose monitor, wherein the at least one sensor electrode is configured to sense signals indicative of interstitial glucose level of a patient;
- and
- causing delivery of the cleaning electrical current to the at least one sensor electrode, the cleaning electrical current being one or more electrochemical cleaning pulses configured to at least partially remove, in vivo and from the sensor electrode, excipients associated with the delivery of a fluid that includes insulin.
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, configure a processor to:
- determine, via one or processors implemented in circuitry and in communication with a memory of a device comprising a glucose monitor, that a cleaning electrical current should be delivered to at least one sensor electrode of the glucose monitor, wherein the at least one sensor electrode is configured to sense signals indicative of interstitial glucose level of a patient;
- and
- cause delivery of the cleaning electrical current to the at least one sensor electrode, the cleaning electrical current being one or more electrochemical cleaning pulses configured to at least partially remove, in vivo and from the sensor electrode, excipients associated with the delivery of a fluid that includes insulin.
