A medical device includes an interface unit body, which is configured to hold a portion of a flexible infusion tube. A hinge insert is fixed to the interface unit body and is configured to engage a hinge receptacle, which defines a hinge axis, on an infusion pump. A catch insert is fixed to the interface unit body and is configured to lock onto a catch receptacle on the infusion pump upon rotation of the mechanical interface unit about the hinge axis while the hinge insert engages the hinge receptacle, so as to bring the tube into engagement with a peristaltic mechanism of the infusion pump in order to enable the peristaltic mechanism to propel a fluid through the tube.

Peristaltic infusion pump with locking mechanism

The present invention includes a finger-type peristaltic pump with a ribbed anvil. According to some embodiments, a finger type peristaltic pump may comprise a plurality of pressing fingers, an infusion tube and a passive interfacing mechanism. The passive interfacing mechanism may comprise a channel, groove or other suitable mount for placing and mounting an infusion tube such that the pressing fingers are positioned on one side of the tube and the ribbed anvil on the opposite side. The pressing fingers may be positioned to apply an approximately perpendicular force on the tube, pressing it against the ribbed anvil, thus causing a pumping action.

Finger type peristaltic pump comprising a ribbed anvil

A peristaltic pump which includes: (a) a plurality of effecters, actuated in a periodic manner upon by obstructive forces of a flexible infusion tube so that flow of infusion fluid is provided along the infusion tube, the magnitude of the obstructive forces are dependent upon the displacement of the moving effecters, and (b) a plurality of balancing magnets providing balancing forces upon one or all of the moving effecters, the balancing forces at each point along the path of motion of the moving effecters being of approximately equal magnitude to that of the obstructive forces at the point, such that the parasitic output due to work performed against the obstructive forces is approximately zero and yield is maximized.

Magnetically balanced finger-type peristaltic pump

The invention provides a finger-type peristaltic pump () having a body () and a housing (). The body contains two or more finger-type valves () and a processor () configured to operate the valves according to a predetermined temporo-spatial pattern. The housing has a passageway () configured to receive a conduit. The housing has a first position in which a conduit in the passageway is positioned adjacent to the valve fingers, and a second position in which a conduit in the passageway is not adjacent to the valve fingers. The invention also provides a housing for use in the pump of the invention.

A peristaltic pump includes a plurality of effecters, actuated in a periodic manner upon by obstructive forces of a flexible infusion tube so as flow of infusion fluid is provided along said infusion tube, the magnitude of the obstructive forces being dependent upon the displacement of said moving effecters; and a plurality of balancing magnets providing balancing forces upon one or all the moving effecters, the balancing forces at each point along the path of motion of the moving effecters being of approximately equal magnitude to that of the obstructive forces at the point; such that the parasitic output due to work performed against the obstructive forces is approximately zero and yield is maximized.

The present invention discloses a finer-type peristaltic infusion pump comprising a ribbed anvil. More specifically, a finger-type peristaltic pump, comprising a plurality of pressing-fingers, infusion-tube, and a passive interfacing mechanism is disclosed. The passive interfacing mechanism comprises of means for accommodating said flexible infusion tube and mounting the tube in a location suitable for the pressing-fingers to apply an approximated perpendicular force on said tube to squeeze it; a ribbed anvil rigidly supporting the tube on opposite side to the pressing fingers when it is pressed by said finger; said anvil comprising a plurality of ribs selected from one or more ribs of a group including a plurality of ribs oriented to face said fingers' tip, a plurality of ribs located in between said fingers, or any combination thereof.

Finger-type peristaltic pump comprising a ribbed anvil

A pump for generating fluid flow in an elastic tubular conduit. The pump comprises a plurality of electrically operated valves, each valve being positionable adjacent to the conduit. Each valve has a valve head configured to alternate from a first position in which the lumen of the conduit adjacent to the valve head is unobstructed and a second position in which the lumen of the conduit adjacent to the valve head is obstructed. The pump also comprises a driver configured to control the positions of the valve heads, so as to execute a predetermined temporo-spatial array of valve head positions.
