MEDICATION INFUSION SYSTEM AND METHOD
First Claim
1. A method for coupling a first reservoir to a controller of a system for percutaneous infusion of an internal wound site, the controller having a motor operable to urge a first fluid from the first reservoir toward the internal wound site, the motor having an axis of rotation, the method comprising:
- aligning a mating surface coupled to the first reservoir with a mating surface of the controller; and
moving the first reservoir along an attachment plane substantially parallel to at least one of the axis of rotation and an output shaft coupled to the motor to drive a pump to mate the mating surfaces together, thereby positioning the first reservoir alongside the motor.

Abstract
A medication infusion system may include a controller and a reservoir module including a reservoir containing medication to be delivered to an internal wound site via the controller. The controller may have a peristaltic pump driven by a motor to urge medication to flow toward the internal wound site. The controller and the reservoir module may each have a mating surface oriented such that the reservoir module can slide into engagement with the controller along a direction parallel to an axis of rotation of the motor. The mating surfaces may have features such as dovetails that facilitate secure assembly and retention. A reservoir module may include only a single reservoir for infusion, or two separate reservoirs for infusion and aspiration. One single controller may be capable of mating with either type of reservoir module to provide only infusion, or infusion combined with aspiration, as desired.

10. A method for percutaneously infusing an internal wound site, the method comprising:
-
determining whether aspiration of the internal wound site is to be carried out; selecting one of a first reservoir module and a second reservoir module based on whether aspiration of the internal wound site is to be carried out, the first reservoir module comprising a first reservoir connectable to infuse the internal wound site with a first fluid, and a second reservoir connectable to aspirate a second fluid from the internal wound site, and a second reservoir module comprising a first reservoir connectable to infuse the internal wound site with the first fluid, exclusively of any second reservoir connectable to aspirate the second fluid from the internal wound site; and mating the selected reservoir module to a controller such that the controller is able to urge the first fluid to flow toward the internal wound site. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
