Finger type peristaltic pump comprising a ribbed anvil

1. An interface configured to be placed in conjunction with a finger-type peristaltic pump including a plurality of fingers, said pump having a pumping cycle of alternating linear motion of each finger, said interface comprising:

a conduit having a compressible segment and positioned within said interface such that when said interface is mounted on the pump the alternating linear motion of the fingers causes fluid to flow through the conduit by applying a series of compressive forces on said conduit, thereby defining a set of contact points on the conduit where fingers of the pump contact the conduit during the alternating linear motion of the fingers;

a conduit accommodation configured to receive said conduit and removably mount said interface to the finger type peristaltic pump;

and

a ribbed anvil positioned within said interface so as to contact a first surface of said conduit opposite a second surface of the conduit contacted by the fingers and having a longitudinal dimension perpendicular to the linear motion of the fingers, said ribbed anvil comprising:

(i) a first set of protruding ribs positioned directly across from each of the contact points, each of said first set of ribs having a flat surface perpendicular to the linear motion of the fingers configured to provide a counterforce to a compressive force produced by each of the plurality of fingers, when said interface is mounted to the pump; and

(ii) a second set of protruding ribs positioned such that the ribs of said second set of ribs alternate with the ribs of said first set of ribs, and such that the ribs of said second set of ribs are positioned to interface with the first surface of said conduit opposite the second surface of the conduit contacted by the fingers in between said contact points wherein said second set of ribs is configured to support the conduit when compressed.

2. The interface of claim 1 , wherein the conduit further comprises a tube.

3. The interface of claim 1 , wherein the conduit includes a silicon element.

4. The interface of claim 1 , wherein the fingers are configured to cause fluid to flow through the conduit in substantially a first direction and the ribbed anvil is configured to limit fluid from flowing in substantially the opposite direction.

5. The interface of claim 1 , wherein, at one of the first set of ribs are of changing height thus enabling calibrating the squeezed volume of the infused fluid per pumping cycle.

6. The interface according to claim 5 , wherein at least one rib of said first set of ribs has a different width than other ribs of said first set of ribs.

7. The interface according to claim 1 , further comprising at least one of the active elements from the group consisting of: a pistol, a hinge, a cam, a wheel, a sealing membrane and a gasket.

8. The interface of claim 1 , wherein the first and second set of ribs do not directly contact said conduit.

9. A system for pumping fluid through a conduit, said system comprising:

a finger-type peristaltic pump including a plurality of fingers having an elongated body and pointed ends, said pump having a pumping cycle of alternating linear motion of each finger; an interface comprising:

a housing configured to removably mount to the finger type peristaltic pump, said housing further configured to receive a conduit within said housing, the conduit having a compressible segment and positioned within said housing such that when said housing is mounted on the pump, the alternating linear motion of the fingers causes fluid to flow through the conduit by the pointed ends applying a series of compressive forces on said conduit, thereby defining a set of contact points on the conduit where the pointed ends of the fingers contact the conduit during the alternating linear motion of the fingers; and

a ribbed anvil positioned within said housing so as to contact a first surface of said conduit opposite a second surface of the conduit contacted by the fingers and having a longitudinal dimension perpendicular to the linear motion of the fingers the ribbed anvil comprising:

a first set of protruding ribs positioned across from the contact points and each of said first set of ribs having a flat surface perpendicular to the linear motion of the fingers narrower than a width of said elongated body configured to provide a counterforce to compressive forces produced by the plurality of fingers, when said housing is mounted to the pump; and

a second set of protruding ribs positioned such that the ribs of said second set of ribs alternate with the ribs of said first set of ribs, and such that the ribs of said second set of ribs are positioned to interface with the first surface of said conduit opposite the second surface of the conduit contacted by the fingers in between said contact points wherein said second set of ribs is configured to support the conduit when compressed.

10. The interface of claim 9 , wherein the conduit further comprises a tube.

11. The interface of claim 9 , wherein the conduit includes a silicon element.

12. The interface of claim 9 , wherein the fingers are configured to cause fluid to flow through the conduit in substantially a first direction and the ribbed anvil is configured to limit fluid from flowing in substantially the opposite direction.

13. The interface of claim 9 , wherein, at one of the first set of ribs are of changing height thus enabling calibrating the squeezed volume of the infused fluid per pumping cycle.

14. The interface according to claim 13 , wherein at least one rib of said first set of ribs has a different width than other ribs of said first set of ribs.

15. The interface according to claim 9 , further comprising at least one of the active elements from the group consisting of: a pistol, a hinge, a cam, a wheel, a sealing membrane and a gasket.
