US 2022/0178362 A1 · PERISTALTIC PUMP SYSTEMS

Abstract

A peristaltic pump system is disclosed and can include a rigid backing and a rotor assembly comprising a central hub. The central hub can rotate along a central axis extending in an axial direction. The central hub can include one or more ball bearings or one or more rollers that are configured to rotate about a respective roller axis that intersects a central axis of the central hub. Located between the rigid backing and the rotor assembly can be tubing or a flow channel that is defined by the rigid backing and an elastomeric sheet. As the central hub rotates, the one or more rollers or ball bearings are configured to push against the tubing or the flow channel in the axial direction and can move along the tubing or the flow channel to move fluid through the tubing or the flow channel.

Dependent claims

A peristaltic pump system comprising:

a cartridge comprising:
a reservoir configured to store an amount of a fluid;
and
tubing having a first end in fluid communication with the reservoir and a second end in fluid communication with an outlet of the cartridge, the tubing being configured to flow the fluid therethrough;
and
a rotor assembly comprising:
a central hub configured to rotate about a central axis extending in an axial direction;
and
one or more rollers each configured to rotate about a respective roller axis that intersects the central axis of the central hub,
wherein as the central hub rotates, the one or more rollers are configured to push against tubing and the cartridge in the axial direction and move along tubing, thereby impinging tubing at a moving point of contact to move the fluid through the tubing.
