Infusion pump with blood glucose alert delay
An apparatus comprising a pump, a user interface, and a controller communicatively coupled to the pump and the user interface. The controller is adapted to receive information relating to a blood glucose level of a user, determine whether the blood glucose level differs from a target blood glucose level by a threshold value, and selectively provide or delay provision of an alert notifying the user to check the user's blood glucose level. Other devices, systems, and methods are disclosed.
1. An infusion pump system, comprising:
a pump configured to deliver a medicament to a user;
a user interface; and
a controller communicatively coupled to the pump and the user interface, the controller adapted to:
receive information relating to a blood glucose level of the user;
determine that the information indicates that the blood glucose level of the user differs from a target blood glucose level by a threshold value; and
selectively delay provision of an alert notifying the user to check the user's blood glucose level for a predetermined duration after the determination that the information indicates that the blood glucose level of the user differs from the target blood glucose level by the threshold value.
2. The infusion pump system of claim 1 , wherein the controller is configured to randomly determine whether to delay the alert notifying the user to check the user's blood glucose level.
3. The infusion pump system of claim 2 , wherein the controller randomly determines whether to delay the alert notifying the user to check the user's blood glucose level based on a measure of a past stability of the blood glucose level of the user.
4. The infusion pump system of claim 1 , wherein the controller is configured to delay the alert notifying the user to check the user's blood glucose level when a bolus of insulin has previously been delivered to the user within a predetermined time of the determination that the information indicates that the blood glucose level differs from the target blood glucose level by the threshold value.
5. The infusion pump system of claim 4 , wherein the bolus of insulin is a meal bolus.
6. The infusion pump system of claim 1 , further comprising a wireless communications port, and wherein the controller is configured to receive the information relating to the blood glucose level of the user from a glucose monitor through the wireless communication port.
7. The infusion pump of claim 6 , wherein the glucose monitor is a continuous blood glucose monitor.
8. The infusion pump system of claim 1 , wherein the controller is configured to determine that the blood glucose level of the user differs from the target blood glucose level by the threshold value when the information indicates that the blood glucose level of the user is higher than the target blood glucose level by the threshold value.
9. An infusion pump system, comprising:
a pump configured to deliver a medicament to a user, including a meal bolus of medicament delivered to counteract carbohydrates consumed by a user in a meal;
a user interface; and
a controller operatively connected to the pump and the user interface, the controller adapted to:
receive information relating to a blood glucose level of the user;
determine from the information that the blood glucose level of the user is higher than a threshold blood glucose level; and
selectively provide, via the user interface, an alert indicating a high blood glucose level when the information indicates that the blood glucose level of the user is higher than the threshold blood glucose level,
wherein provision of the alert indicating a high blood glucose level is delayed if the blood glucose level of the user is determined to be higher than the threshold blood glucose level within a predetermined period of time of the pump previously delivering a meal bolus.
10. The infusion pump system of claim 9 , wherein the alert indicating a high blood glucose level includes an instruction for the user to check the user's blood glucose level.
11. The infusion pump system of claim 9 , further comprising a wireless communications port, and wherein the controller is configured to receive the information relating to the blood glucose level of the user from a glucose monitor through the wireless communication port.
12. The infusion pump system of claim 11 , wherein the glucose monitor is a continuous blood glucose monitor.
13. An apparatus, comprising:
an input configured to receive information relating to a blood glucose level of a user;
a user interface; and
a controller communicatively coupled to the user interface and the input, the controller including an alert module, wherein the alert module includes a timer and is configured to selectively provide an alert a predetermined duration after the information indicates that the blood glucose level of the user differs from a target blood glucose level by a threshold value.
14. The apparatus of claim 13 , further comprising a pump configured to deliver medicament to a user.
15. The apparatus of claim 14 , wherein the controller is configured to provide the alert a predetermined duration after the information indicates that the blood glucose level of the user differs from a target blood glucose level by a threshold value when a bolus of insulin has previously been delivered to the user within a predetermined time of the information indicating that the glucose level differs from the target blood glucose level by the threshold value.
16. The apparatus of claim 15 , wherein the bolus of insulin is a meal bolus.
17. The apparatus of claim 13 , wherein the input is configured to receive the information relating to the glucose level of the user wirelessly from a glucose monitor.
18. The apparatus of claim 17 , wherein the glucose monitor is a continuous blood glucose monitor.
19. The apparatus of claim 13 , wherein the controller is configured to find that the blood glucose level of the user differs from the target blood glucose level by the threshold value when the blood glucose level of the user is higher than the target blood glucose level by the threshold value.
