The all-new design of the Easy-Load® 3 features an automatic retention mechanism that makes loading and unloading tubing easier than ever. The spring-loaded occlusion lever opens the occlusion bed and simultaneously retracts the tubing retainers so that tubing slips right in. Close the lever and start the pump—the retainers automatically grip and hold the tubing securely in place. The occlusion bed applies optimal occlusion force and the wide occlusion angle prevents fluid backflow up to the rated pressure of the tubing.
