摘要： 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, through a conduit. When the conduit is not tensioned via engagement with the pump, a valve blocks fluid flow to prevent unrestricted flow of medication. The valve may have a tapered plunger separated from an annular valve seat by a portion of the conduit that elongates under tension to enable withdrawal of the plunger from the valve seat. Alternatively, the valve may have features such as a spherical plunger between two annular valve seats, a rigid tubular member biased with respect to the conduit, or an opening in the conduit that moves axially or radially to enable fluid flow.

摘要： 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, through a conduit. A blockage sensor disables the motor and provides an alarm if the tube is blocked. The blockage sensor detects distention of a preferentially distendable portion of the tube, which may be routed about a constraining member. When blockage occurs, the tube distends preferentially along a direction generally parallel to the radius about which the tube bends. The blockage sensor may include a variety of switching elements, such as a pushbutton switch, a metal ring encircling the tube to make contact between conductors, and/or a metal bridge bendable to make contact between conductors.
