Medication infusion and aspiration system and method
First Claim
1. A system for percutaneous infusion of an internal wound site, the system comprising:
- a first reservoir contained by a rigid housing, wherein the first reservoir is shaped to contain a first fluid;
a controller comprising a motor and a peristaltic pump driven by the motor to urge the first fluid toward the internal wound site, the motor having an axis of rotation;
a tube configured to engage the peristaltic pump to convey the first fluid, wherein the tube is coupled to the rigid housing at two locations along a length of the tube; and
a catheter configured to convey the first fluid from the tube to the internal wound site and to infuse the first fluid into the internal wound site;
wherein, in response to motion of the first reservoir along an attachment plane, the first reservoir is attachable to the controller to position the first reservoir alongside the motor;
wherein the attachment plane is substantially parallel to at least one of the axis of rotation and an output shaft coupled to the motor to drive a pump.

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.

13. A system for percutaneous infusion of an internal wound site, the system comprising:
-
a motor operable to urge a first fluid from a first reservoir through a tube toward the internal wound site, the motor having an axis of rotation; and a mating surface extending alongside the motor, to receive a rigid housing containing the first reservoir in response to motion of the rigid housing 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; wherein the motor is further operable to urge a second fluid from the internal wound site to a second reservoir; wherein the tube is configured to engage the pump to convey the first fluid, wherein the tube is coupled to the rigid housing at two locations along a length of the tube. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A system for percutaneous infusion of an internal wound site, the system comprising:
-
a first reservoir module comprising a first reservoir connectable to supply a first fluid to the internal wound site, and a rigid housing shaped to retain the first reservoir exclusively of any other reservoir connectable to provide fluid communication with the internal wound site; a second reservoir module comprising a first reservoir connectable to supply the first fluid to infuse the internal wound site, and a second reservoir connectable to receive a second fluid aspirated from the internal wound site; a controller matable to either of the first and second reservoir modules exclusively of the other of the first and second reservoir modules such that the controller is able to urge the first fluid to flow toward the internal wound site, wherein the controller comprises a pump; and a tube configured to engage the pump to convey the first fluid, wherein the tube is coupled to the rigid housing at two locations along a length of the tube. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A system for percutaneous infusion of an internal wound site, the system comprising:
-
a reservoir module comprising a substantially rigid mating surface and a first reservoir contained by a rigid housing, wherein the first reservoir is shaped to contain a first fluid; a controller comprising a motor and a peristaltic pump driven by the motor to urge the first fluid toward the internal wound site, the motor having an axis of rotation, the controller further comprising a mating surface having a generally planar shape substantially parallel to the axis of rotation; and a tube configured to engage the peristaltic pump to convey the first fluid, wherein the tube is coupled to the rigid housing at two locations along a length of the tube; wherein the mating surface of the controller is shaped to receive the mating surface of the reservoir module in response to motion of the reservoir module 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 the peristaltic pump to position the first reservoir alongside the motor. - View Dependent Claims (30, 31, 32, 33, 34, 35)
