Abstract

A medication delivery system for delivering medicament to a body of a user. The medication delivery system may include a housing having a plurality of medicament reservoirs therein, a first sensor configured to continuously monitor a parameter of the body, and a pump mechanism configured to pump medicament from each of the plurality of medicament reservoirs to a delivery mechanism having a portion disposed within the body of the user.

Claims

1. A miniature medication delivery system for delivery of medicament to a body of a user, comprising:

a housing configured to be secured proximate to the body, the housing comprising control electronics, a power source, a plurality of electromagnetic coils, and a sensor support socket;

a first sensor configured to continuously monitor a parameter of the user removably connectable through the sensor support socket, wherein the first sensor is configured to be inserted into the body of the user through the sensor support socket;

a cartridge system removably connectable to the housing comprising;

a first reservoir comprising a first medicament;

a second reservoir comprising a second medicament; and

a pump mechanism configured to pump medicament from the first reservoir to a delivery mechanism having a portion disposable within the body of the user, wherein the control electronics are in electrical communication with the first sensor, the pump mechanism comprising;

a first pump insert body in fluid communication with the first reservoir, wherein the first pump insert body comprises a first opening that contains a first magnet, a plurality of fluid channels, a fluid receiving opening, and a fluid discharge opening;

a second pump insert body in fluid communication with the second reservoir, wherein the second pump insert body comprises a second opening that contains a second magnet;

a flexible member disposed in between the first and second pump insert bodies, wherein the flexible member is operably coupled to first and second magnets,

wherein the plurality of electromagnetic coils are configured to selectively control position of one or both of the first and second magnets relative to the plurality of electromagnetic coils in order to deliver the first and the second medicament.

2. The miniature medication delivery system of claim 1, wherein the first medicament comprises a fast-acting insulin, and the second medicament comprises a slow-acting insulin.

3. The miniature medication delivery system of claim 1, wherein the parameter is blood glucose.

4. The miniature medication delivery system of claim 1, wherein the first sensor comprises a cannula configured to be disposed within a user'"'"'s blood stream.

5. The miniature medication delivery system of claim 1, wherein the cartridge system is disposable.

6. The miniature medication delivery system of claim 1, wherein the housing further includes a display screen.

7. The miniature medication delivery system of claim 1, wherein the delivery mechanism includes an infusion set having a catheter.

8. The miniature medication delivery system of claim 1, wherein the pump mechanism is configured to pump the first medicament at a first rate of delivery and the second medicament at a second rate of delivery.

9. The miniature medication delivery system of claim 1, wherein the housing includes a plurality of surfaces, and at least one of the plurality of surfaces includes an adhesive material thereon.

10. The miniature medication delivery system of claim 1, wherein the first medicament is different from the second medicament.

11. The medication delivery system of claim 1, wherein the housing includes a height of approximately 0.5 inches.

13. The miniature medical delivery device of claim 1, wherein one or both the first reservoir and the second reservoir are refillable.

14. The miniature medical delivery device of claim 13, wherein a release of one or both the first medicament and the second medicament occurs automatically based on receiving parameter data outside of a predefined threshold range of the parameter.

15. The miniature medical delivery device of claim 1, wherein a release of one or both the first medicament and the second medicament occurs when the control electronics receives a release prompt.

16. The miniature medical delivery device of claim 1, wherein a parameter level is periodically transmitted to an external device.

17. The miniature medical delivery device of claim 1, wherein a dosage quantity of one or both the first medicament and the second medicament is determined based on receiving parameter data outside of a predefined threshold range of the parameter.

18. The miniature medical delivery device of claim 1, wherein the power source is rechargeable.
