1. A portable kit for providing pain relief comprising:
- a catheter for delivering an anesthetic-containing fluid adjacent a wound site in a body;
tubing attached to the catheter and having a lumen in fluid communication with a lumen of the catheter;
a pump adapted to deliver fluid, the pump including an outlet in fluid communication with the tubing, the pump further including an inlet port for filling a reservoir of the pump;
the pump affixable to the body to permit portability;
an electronic valve disposed between the catheter and the reservoir in a first flow path;
a controller that generates signals to control operation of the electronic valve; and
instructions on a controller interpretable medium that when interpreted by the controller cause the controller to be able to selectively place the electronic valve in each of three conditions, the first condition causing the electronic valve to periodically open and close to achieve a first output flow rate through the catheter, a second condition causing the electronic valve to open and close to achieve a second output flow rate, and the third condition causing closure of the electronic valve.

Abstract
An electronic controller is provided for controlling the evacuation of fluid from one or more fluid reservoirs. The controller includes a plurality of sensors that sense environmental factors and the controller adjusts the evacuation of fluid from the bladder(s) using information gathered by the sensors.

8. A portable kit for providing pain relief comprising:
-
a first pump having a first reservoir that when filled with an anesthetic provides a first pressure biased to evacuate the anesthetic from the first pump;
the first pump being constructed such that the first pressure varies based upon the first reservoir experiencing environment induced pressure variations; andan electronic controller that controls the evacuation of anesthetic from the first reservoir to compensate for the variability in the first pressure to achieve a desired output flow that is independent of the environment induced pressure variations experienced by the first reservoir. - View Dependent Claims (9, 10, 11, 12)

13. A portable kit for providing medication to tissue comprising:
-
a pump having a first reservoir, the first reservoir, when filled with a first fluid provides a first pressure biased to evacuate the first fluid from the first reservoir; and an electronic controller that controls the evacuation of fluid from the first reservoir, the electronic controller being able to receive input indicative of the activity of a patient, the electronic controller adjusting an output flow from the first reservoir at least partially based upon the input indicative of the activity of the patient. - View Dependent Claims (14, 15, 16, 17)

18. A portable kit for providing fluid to tissue comprising:
-
a pump having a first reservoir and a second reservoir, an electronic controller that controls the evacuation of fluid from the first and second reservoirs, the electronic controller being able to receive input selected from the group including input indicative of patient status and input indicative of atmospheric status, the electronic controller adjusting output flows from the first and second reservoirs at least partially based upon the received input to achieve a output mixture of the first and second fluids, the mixture having a first ratio of the first fluid to the second fluid. - View Dependent Claims (19, 20)

21. A portable kit for providing fluid to tissue comprising:
-
a pump having a first reservoir and a second reservoir, an electronic controller that controls the evacuation of fluid from the first and second reservoirs, the electronic controller being programmable to cause an output flow of the pump to vary as a function of time. - View Dependent Claims (22, 23)
