Abstract

A device for automatically delivering a basal flow of a medication to a patient while also permitting manual control over bolus delivery of the medication is disclosed. The device is configured to permit bolus delivery to occur precedent, concurrent with, or subsequent to the basal delivery. A method for performing the same is also disclosed.

Claims

2-1. The device of claim 1, wherein the pressure control element comprises a piston.

14. A device for delivering a fluid to a biological tissue comprising:

a flexible reservoir containing the fluid and having a fluid pressure;

a pressure control element in fluid communication with the reservoir, wherein the pressure control element is configured to controllably alter the fluid pressure in the reservoir;

an electric control configured to control the pressure control element; and

a manual control configured to control the pressure control element.

15. A method for delivering a fluid to a biological tissue comprising:

delivering a basal infusion of the fluid from a reservoir of a fluid delivery device, wherein the delivering of the basal infusion comprises a first changing of the pressure of the reservoir, and wherein the first changing of the pressure comprises moving a pressure control element with an electric motor; and

delivering a bolus of the fluid from the fluid delivery device, wherein the delivering of the bolus of the fluid comprises a second changing of the pressure of the reservoir, and wherein the second changing of the pressure comprises moving the pressure control element with a manual force.

16. The method of claim 15, further comprising stopping the delivering of the basal infusion of the fluid before delivering the bolus of the fluid.

17. The method of claim 15, wherein the delivering of the basal infusion further comprises moving the pressure control element with a spring after the first changing of the pressure of the reservoir.

18. The method of claim 17, wherein the delivering of the bolus infusion further comprises moving the pressure control element with the spring after the second changing of the pressure of the reservoir

19. The method of claim 16, further comprising removing the basal control before the the delivering of the bolus of fluid.

20. The method of claim 16, further comprising adjusting a volume of the bolus of the fluid before delivering the bolus of the fluid, wherein adjusting comprises adjusting a limit of the motion of the pressure control element.
