Abstract
A portable insulin pump can utilize readings from a sensor incorporated into an infusion set used with the pump to deliver insulin to a patient to determine if the infusion set is or is likely to become dislodged from the patient. Readings from the sensor that are inconsistent with expected readings or a range of expected readings can indicate that the infusion set has become dislodged from the patient.
Claims20
A method of providing diabetes therapy to a patient with a portable infusion pump, comprising:
- delivering medicament to a patient with the portable infusion pump through a cannula inserted into the patient;
- monitoring glucose levels of the patent with data obtained by a glucose sensor while the medicament is delivered to the patient;
- determining that the monitored glucose levels are inconsistent with expected readings;
- determining, due to the monitored glucose levels being inconsistent with expected readings, that the patient may not be receiving the medicament through the cannula;
- and
- providing an alert to the patient to check the portable infusion pump in response to the determination that the patient may not be receiving the medicament through the cannula.
A method of providing diabetes therapy to a patient with a portable infusion pump, comprising:
- delivering medicament to a patient with the portable infusion pump through a cannula inserted into the patient;
- monitoring glucose levels of the patent with data obtained by a glucose sensor while the medicament is delivered to the patient;
- determining that the monitored glucose levels are not responding to delivery of the medicament as expected;
- and
- providing an alert to the patient to check the portable infusion pump in response to the determination that the monitored glucose levels are not responding to delivery of the medicament as expected.
A portable infusion pump system, comprising:
- a portable infusion pump including a reservoir configured to contain a medicament and a delivery mechanism configured to deliver the medicament to a patient through a cannula inserted into the patient;
- a receiver adapted to receive data relating to glucose levels of the patient obtained by a glucose sensor;
- and
- a processor configured to:
- cause the delivery mechanism to deliver the medicament to the patient through the cannula;
- monitor glucose levels of the patent with the data obtained by the glucose sensor while the medicament is delivered to the patient;
- determine that the monitored glucose levels are inconsistent with expected readings;
- determine, due to the monitored glucose levels being inconsistent with expected readings, that the patient may not be receiving the medicament through the cannula;
- and
- provide an alert to the patient to check the portable infusion pump in response to the determination that the patient may not be receiving the medicament through the cannula.
