A catheter occlusion prevention or remediation system for use with catheter-based therapeutic or medical liquid delivery to a patient. The system is an adjunct to a catheter liquid delivery arrangement that typically includes an infusion pump hooked to the patient. The system includes a drive that displaces a pulse effector against liquid in a pulse chamber in fluid-flow communication with liquid in the catheter to create a pressure pulse that opens occlusions, breaks away occlusions being formed, and prevents occlusion formation. In one embodiment, the drive charges an accumulator that displaces the pulse effector during a period of low pump motor activity maximizing onboard battery life. In another embodiment, the drive is an actuator with an armature that displaces a plunger into the pulse chamber to form the pulse. The resultant pulses are of sufficient duration and pressure above working pressure to achieve occlusion prevention and remediation.
An occlusion prevention or remediation apparatus for a medication delivery device that communicates medication-containing liquid to a catheter line connected to a patient, the occlusion prevention or remediation device comprising a pulse generator that causes a pulse to form in medication-containing liquid in the catheter line downstream of the medication delivery device.
