The present disclosure is directed to endoscope cleaning systems and methods. The endoscope cleaning system can include a pump housing that houses a peristaltic pump, an endoscope sheath fluidly connected to the pump housing, and a pump control communicatively coupled to the peristaltic pump. Upon activation of the pump control, the peristaltic pump can supply fluid to the endoscope sheath for cleaning an endoscope. Upon deactivation of the pump control, the peristaltic pump can remove residual fluid from the endoscope.

A peristaltic pump is provided for conveying a fluid pumping medium through a compressible hose. The pump is designed particularly for use in an aquarium, terrarium, or vivarium for metering fluids accurately and reliably by eliminating permanent tubing deformation and random stopping positions of rollers.

A pump is provided that includes a tube 1, tube rotors 21A, 21B, and 21C in contact with the tube 1, a case 3 containing the tube 1 and tube rotors 21A, 21B, and 21C, and a drive apparatus 10 that rotates the tube rotors 21A, 21B, and 21C from outside the case 3 without contacting the tube rotors 21A, 21B, and 21C.

The invention provides a rotor for a peristaltic pump, the rotor comprising a body for rotation about an axis, the body having a first side and a second side, the body supporting a plurality of spaced first rollers extending from the body on the first side, the first rollers positioned at a first common radius from the axis, the body further supporting a plurality of spaced second rollers extending from the body on the second side, the second rollers positioned at a second common radius from the axis. The invention extends to a peristaltic pumping unit comprising such a rotor assembled with a first stator and a second stator, the first stator having one or more compressible fluid channels arranged to be compressed by said first rollers and the second stator having one or more compressible fluid channels arranged to be compressed by said second rollers. The invention also concerns a stator for a peristaltic pump, having a body with a planar surface and two or more fluid channels, each fluid channel having a compressible arcuate portion on or in the planar surface of the stator, the arcuate portions arranged to be compressed by a plurality of rollers mounted on a rotor, the arcuate portions each connecting to further portions of the fluid channel extending in a direction away from the planar surface such that the fluid channels take a three dimensional path within the body of the stator.

A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.

A holder for a curved duct portion of a tube pump. The holder includes a supply-side connector which includes a first cavity and a first plate connected together, the first cavity being adapted for receiving an end of the curved duct portion, and a discharge-side connector including a second cavity and a second plate connected together, the second cavity being adapted for receiving another end of the curved duct portion, where the connectors are movable the one with respect to the other between a storage configuration, in which the supply-side connector is positioned away to the discharge-side connector, and an operating configuration, in which the supply-side connector is close to the discharge-side connector and in which the first and second plate are engaged together substantially on a same plane.

A pump comprising a housing; a motor mounted in the housing and configured to drive a rotor mounted on a shaft connected to the motor, and a first connector and a second connector each secured to the housing. The first and second connectors are in fluid communication by a tube arranged in the housing. The first connector is configured to connect to a first fluid line and the second connector is configured to connect to a second fluid line. In use, the rotor is configured to urge fluid within the tube from the first connector to the second connector when driven by the motor. The first and second connectors are releasably secured to the housing.

A boring device according to one embodiment of the present invention includes: a cutting edge; a drive unit that rotationally drives the cutting edge; a feed flow path through which a cooling liquid is fed to the cutting edge; and a tube pump that forces the cooling liquid in the feed flow path to flow to the cutting edge. The tube pump includes a feed tube constituting a part of the feed flow path and a first pressing mechanism that presses the feed tube, and the first pressing mechanism is driven by the drive unit.

An solution transfer device comprises a pump 60 and a substrate 70. The pump 60 comprises a tube 1 for transferring a solution; tube rotors 21A, 21B, 21C, which contact the tube 1; and a driver 10 for transferring a solution within the tube 1 by rotating the tube rotors 21A, 21B, 21C without contacting the tube rotors 21A, 21B, 21C. The substrate 70 is provided with a solution-transferring flow path that is connected to the tube 1 of the pump 60.

The present invention is directed to a peristaltic pump (1), comprising a rotary body (2) with a plurality of squeeze sections (3) arrange circularly distributed and moveable about a rotation axis (A), a tube carrier (4) for carrying a flexible tube (5) along an arcuate engagement section (6) arcuately surrounding the rotary body (2), and an actuator (7) for selectively moving the tube carrier (4) relative to the rotary body (2) between a pump position in which a flexible tube (5) carried by the tube carrier (4) be positioned in engagement between the engagement section (6) and at least one of the squeeze sections (3) to allow for a pumping action when moving the rotary body (2) about the rotation axis (A), and a release position in which the flexible tube (5) carried by the tube carrier (4) be disengage from the plurality of squeeze sections (3) to allow for free flow through the flexible tube (5). The present invention is further directed to a pump system comprising the peristaltic pump (1), a flexible tube (5) be functionally carried by the tube carrier (4), a product supply be fluidly connected to an upstream end of the flexible tube (5), and a product discharge section be fluidly connected to a downstream end of the flexible tube (5). Moreover, the present invention is directed to a method for pumping a fluid by use of the pump system (100).
