Abstract

Apparatuses, systems and methods for the wireless communication of medical devices in a subcutaneous fluid delivery system are disclosed. A system for subcutaneous fluid delivery includes a primary patch pump adapted to attach a first infusion cannula to a user and to perform a plurality of primary patch pump functions, and a secondary patch pump adapted to attach a second infusion cannula to a user. The secondary patch pump is further adapted to perform a plurality of secondary patch pump functions substantially similar to the plurality of primary patch pump functions if an error condition associated with the primary patch pump is determined.

Claims

1. A system for on-body fluid delivery comprising:

a primary user interface device comprising a display and a primary user interface real-time clock;

a primary patch pump comprising a pump mechanism and a primary patch pump real time clock, the primary patch pump adapted to attach a first infusion cannula to a user, the primary patch pump further adapted to perform a plurality of primary patch pump functions; and

a secondary patch pump comprising a secondary patch pump real time clock, the secondary patch pump adapted to attach a second infusion cannula to a user, the secondary patch pump further adapted to perform a plurality of secondary patch pump functions substantially similar to the plurality of primary patch pump functions if an error condition associated with the primary patch pump is determined;

wherein the primary user interface device, the primary patch pump, and the secondary patch pump are each adapted to enter SLEEP, WAKE, and SNIFF modes in synchronicity with one another based on said real time clocks;

wherein less power is consumed by said display of said primary user interface device and said pump mechanism of said primary patch pump during said SLEEP mode than during said WAKE mode, and wherein communication between devices is checked during SNIFF mode; and

wherein at least one of a SLEEP cycle, a WAKE cycle and a SNIFF cycle of the primary user interface device is synchronized with at least one of a SLEEP cycle, a WAKE cycle and a SNIFF cycle of a primary patch pump to save energy, using the primary user interface real-time clock and the primary patch pump real-time clock.

2. The system for on-body fluid delivery of claim 1, wherein the plurality of primary patch pump functions comprises at least one of:

pairing with a primary user interface;

being filled with a medicament and primed;

deploying a cannula;

initiating a bolus dose or basal rate;

entering a primary patch pump SLEEP mode;

entering a primary patch pump WAKE mode at predetermined primary patch pump WAKE time intervals; and

entering a primary patch pump SNIFF mode for up to a predetermined primary patch pump SNIFF time.

3. The system for on-body fluid delivery of claim 2,

wherein a power level associated with the primary patch pump SLEEP mode is lower than a power level associated with said primary patch pump WAKE mode.

4. The system for on-body fluid delivery of claim 1, wherein the primary patch pump is able to communicate with the secondary patch pump.

5. The system for on-body fluid delivery of claim 1, wherein the primary patch pump comprises one of a completely disposable patch pump and a durable/disposable patch pump.

6. The system for on-body fluid delivery of claim 5, wherein the completely disposable patch pump comprises:

a reservoir to contain medicament;

at least one integral push-button to activate a bolus dose;

a cannula deployment assembly to deploy a cannula;

a pump engine to infuse medicament from the reservoir through the deployed cannula;

a printed circuit board assembly to control operations of at least one of the cannula deployment assembly and the pump engine; and

an adhesive to attach the system to skin.

7. The system for on-body fluid delivery of claim 6, wherein the at least one integral push-button comprises two push-buttons to activate a bolus dose if both push-buttons are depressed simultaneously.

8. The system for on-body fluid delivery of claim 5, wherein the durable/disposable patch pump comprises a durable assembly and a disposable assembly,

wherein the durable assembly comprises:

a pump engine to infuse medicament from the reservoir;

at least one integral push-button to activate a bolus dose; and

a coupler to couple the durable assembly to the disposable assembly; and

wherein the disposable assembly comprises;

a coupler to couple the disposable assembly to the durable assembly;

a connector to electrically connect the disposable assembly to the durable assembly;

a cannula deployment assembly to deploy a cannula;

a reservoir to contain medicament; and

an adhesive to attach the system to skin, and

wherein at least one of the durable assembly and the disposable assembly comprises a printed circuit board assembly to control operations of at least one of the pump engine and the cannula deployment assembly.

9. The system for on-body fluid delivery of claim 8, wherein the at least one integral push-button comprises two push-buttons to activate a bolus dose if both push-buttons are depressed simultaneously.

10. The system for on-body fluid delivery of claim 1, further comprising at least one of a primary user interface and a secondary user interface able to communication with at least one of the primary patch pump and the secondary patch pump.

11. The system for on-body fluid delivery of claim 10, wherein the at least one of a primary user interface and a secondary user interface comprises a timer function enabling bolus infusions at predetermined intervals.

12. The system for on-body fluid delivery of claim 10, wherein the at least one of a primary user interface and a secondary user interface comprises one of a fully-functioning graphical user interface and a minimally-functioning key fob.

13. The system for on-body fluid delivery of claim 12, wherein the minimally-functioning key fob comprises:

a dose setting device adapted to set a bolus dose; and

at least one depressible button adapted to initiate a bolus dose.

14. The system for on-body fluid delivery of claim 13, wherein the dose setting device is a turnable dial.

15. The system for on-body fluid delivery of claim 10, wherein the at least one of a primary user interface and a secondary user interface is able to communicate with a network link.

16. The system for on-body fluid delivery of claim 1, further comprising a primary user interface able to communicate with at least one of the primary patch pump and the secondary patch pump.
