Pump systems with pinch valves for surgical procedures. At least some of the example embodiments are pump systems including a stationary housing defining a front face. A tube support extends outwardly from the front face for aligning and supporting a first tube and a second tube. At least one pinch member is movable relative to the tube support by a power actuator operably coupled to the at least one pinch member and configured to have three orientations that define: a first arrangement of the pinch member relative to the tube support configured to pinch closed the first tube, a second arrangement of the at least one pinch member relative to the tube support configured to pinch closed the second tube, and a third arrangement of the at least one pinch member relative to the tube support configured to pinch closed neither the first tube nor the second tube.

A pump system for an atomizer nozzle system having at least two atomizer nozzles, in particular for an electrohydrodynamic atomizer as well as a method for operating an electrohydrodynamic atomizer, wherein the pump system comprises at least one hose assembly as well as at least one pump rotor (7) and at least one rolling body (6) for forming a rolling region of a peristaltic pump, wherein the hose assembly comprises at least the same number of hose channels as the number of atomizer nozzles, and in that each hose channel is assigned to an atomizer nozzle and connects it to the rolling region.

An embodiment system and method for dispensing multiple dairy products includes a dispenser which houses two or more dairy product bases with different formulations, which may be combined with or without water to create a multitude of homogenous dairy beverages. The two or more dairy product bases may be mixed together first and then separately mixed with water, mixed together simultaneously with water, or mixed together without adding water. They may be mixed together with or without additional flavoring, ingredients, mineral or nutritional additives. The dispenser comprises a pump with a quick-release mechanism to allow for quick and clean maintenance of the system.

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.

A metering unit for the controlled supply of a substance inside an aquarium tank comprises a containment box and a dosimetric pump which is actuated by an electric motor, both being associated with the containment box. The containment box has at least a first connection element and at least a second connection element which is suitable for being connected to a corresponding first connection element of an additional similar metering unit.

A tubing assembly is provided that can comprise a plurality of tubes or lumens that can be disposed within a head of a peristaltic pump. The tubing assembly can provide a flow rate or volume capacity that is generally equal to or greater than that achieved with a comparable prior art tube while operating at higher pressures than that possible using the prior art tube. Further, in accordance with some embodiments, the tubing assembly can achieve a longer working life than a comparable prior art tube, and the load on the pump motor can be reduced such that the pump life is increased and/or a larger pump motor is not required to achieve such advantageous results.

A fluid handling system for a surgical procedure includes a console and a tubing set. The console exhibits a peristaltic pump, a pinch valve, one above the other. Two recessed seats are located to the left and right sides of the pump and valve. The tubing set includes an irrigation tube and an aspiration tube each coupled to a pair of magnetic disks disposable in respective ones of the recessed seats. Upon such disposition, the irrigation tube is disposable in operative engagement with the peristaltic pump and the aspiration tube is insertable into a slot of the pinch valve.
