Integrated patch-pump devices to deliver drugs, e.g., macromolecular drugs that are difficult to deliver through an oral pathway and/or that require transdermal delivery. Embodiments are slim, powerless, painless, and relatively inexpensive. The microfluidic pump is used to drive the fluid flow powered by pressurized air or the user's pulse, and the microneedle array is used to inject the fluid through the skin painlessly. The flow rate generally positively correlates with the actuation pressure. For devices with wider flow channels, the flow rate generally negatively correlates with the actuation frequency, whereas the flow rate increases and then decreases with increasing actuation frequency for devices with narrower flow channels. This property of these devices is beneficial in insulin delivery because the demand for insulin is generally reduced in vigorous exercise (with elevated heart rate/ actuation frequency) and is increased in hypertension patients (with elevated blood/actuation pressure).

The exemplary embodiments provide medicament delivery devices that use cost functions in their control systems to determine medicament dosages. The cost function may have a medicament cost component and a performance cost component. The exemplary embodiments may use cost functions having medicament cost components that scale asymmetrically for different ranges of inputs (i.e., different candidate medicament dosages). The variance in scaling for different input ranges provides added flexibility to tailor the medicament cost component to the user and thus provide better management of medicament delivery to the user and better conformance to a performance target. The exemplary embodiments may use a cost function that has a medicament cost component (such as an insulin cost component) of zero for candidate dosages for a range of candidate dosages (e.g., below a reference dosage).

Invasive glucose sensors and noninvasive glucose sensors may be used in conjunction to improve glucose management for a user. The rate of change (ROC) of glucose levels from a noninvasive glucose sensor may be used rather than or in conjunction with a glucose level of the user from a CGM. A basal insulin delivery rate to the user may be adjusted responsive to the ROC glucose level data from the noninvasive sensor. The glucose level ROC from a noninvasive glucose sensor may be used to predict future glucose level ROCs of the user between operational cycles of an insulin delivery device and/or to identify possible hypoglycemic or hyperglycemic events. These predicted future glucose level ROCs may be used in a cost function of the control system of the insulin delivery device to select basal insulin delivery doses. Glucose level readings may be used to calibrate a noninvasive glucose level sensor.
