Abstract:
1. A peristaltic pump system comprising: a planetary rotor sub-system, including: an occlusion sub-system including: wherein the occlusion system is operable in three modes: a rest mode, wherein the deformable volume achieves the open configuration; an occluded mode, wherein the roller element applies the occluding force to a localized section of the actuator strip bearing surface, deflecting the actuator strip such that the occluding surface deforms the diaphragm, occluding the corresponding section of the deformable volume; and a pressurized mode, wherein the pressure within the deformable volume is higher than ambient pressure, wherein the actuator restraint portion prevents actuator strip deflection, preventing diaphragm expansion, maintaining the volume of the deformable volume and maintaining the pressure within the deformable volume.
