Abstract
A peristaltic pump may include a rotor rotatably mounted between a base of the peristaltic pump head and an end cap of the peristaltic pump head. The peristaltic pump may include an arcuate case between the base and the end cap partially surrounding the rotor. The peristaltic pump may include an arcuate occlusion bed removably mounted between the base and the end cap. The arcuate case and the arcuate occlusion bed form a cylindrical body around the rotor. The peristaltic pump may include a locking handle hingedly mounted to the arcuate occlusion bed, wherein the locking handle includes a bar extending between a pair of cam members, each cam member including a cam slot that engages a respective pin extending from the base and the end cap.
Claims16
A peristaltic pump head, comprising:
- a rotor rotatably mounted between a base of the peristaltic pump head and an end cap of the peristaltic pump head;
- an arcuate case between the base and the end cap partially surrounding the rotor;
- an arcuate occlusion bed removably mounted between the base and the end cap, wherein the arcuate case and the arcuate occlusion bed form a cylindrical body around the rotor;
- and
- a locking handle hingedly mounted to the arcuate occlusion bed, wherein the locking handle includes a bar extending between a pair of cam members, each cam member including a cam slot that engages a respective pin extending from the base and the end cap.
A peristaltic pump head, comprising:
- a rotor rotatably mounted between a base of the peristaltic pump head and an end cap of the peristaltic pump head, wherein the rotor comprises:
- a base plate;
- an end plate;
- a central shaft extending through the base plate and the end plate;
- a central gear driven by the central shaft;
- and
- a plurality of planetary shafts mounted between the base plate and the end plate around the central shaft, each planetary shaft connected to a planetary gear in meshed engagement with the central gear;
- and
- a pair of composite bushings in each of the base and the end cap rotatably retaining the central shaft;
- and
- a pair of composite bushings in the base plate and the end plate retaining each of the plurality of planetary shafts.
A peristaltic pump, comprising:
- a mounting plate attached to an external surface of a housing, the mounting plate having an internal wall defining an opening into the housing for receiving a central rotor shaft of a pump head;
- an annular collar extending from an external surface of the mounting plate and surrounding the opening, the annular collar including a pair of L-shaped slots opening at an exterior surface of the annular collar;
- and
- a lock lever pivotably mounted to the mounting plate and movable between a locked position with an end of the lock lever within one of the L-shaped slots and an unlocked position with the end of the lock lever outside of the L-shaped slot.
