Finger-type peristaltic pump
First Claim
Patent Images
1. A tube to pump interface housing adapted to support a tube, said housing comprising:
- a channel to receive and support a tube;
one or more pump interlock elements adapted to facilitate detachable engagement of said interface with a peristaltic pump;
an anti-free-flow mechanism having a disengaged default state which obstructs flow through the tube when said housing is detached from the pump, and wherein said anti-free-flow mechanism is brought into an engaged default state, allowing fluid to flow through the tube, when said housing is attached to the pump; and
an anti-free-flow override mechanism engageable when said housing is detached from the pump, said override mechanism being configured to, when engaged, mechanically latch said anti-free-flow mechanism in a non-obstructing state allowing fluid to flow through the tube while said housing is detached from the pump.

Abstract
The invention provides a finger-type peristaltic pump (2) having a body (4) and a housing (6). The body contains two or more finger-type valves (16) and a processor (22) configured to operate the valves according to a predetermined temporo-spatial pattern. The housing has a passageway (18) 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.

7. A system for pumping fluid comprising:
-
a peristaltic pump; a flexible tube; and a housing comprising; (1) a channel to receive and support said tube, (2) one or more pump interlock elements adapted to facilitate detachable engagement of said housing with said pump, (3) an anti-free-flow mechanism having a disengaged default state which obstructs flow through said tube when said housing is detached from said pump, and wherein the anti-free-flow mechanism is brought into an engaged default state, allowing fluid to flow through the channel, when said housing is attached to said pump; and (4) an anti-free-flow override mechanism engageable when said housing is detached from said pump, said override mechanism being configured to, when engaged, mechanically latch said anti-free-flow mechanism in a non-obstructing state allowing fluid to flow through said tube while said housing is detached from said pump. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A peristaltic pump comprising:
a pumping mechanism configured to induce flow of a fluid through a flexible tube within a detachable tube-housing, wherein said pump includes one or more interlock elements configured to facilitate detachable engagement of said pump with the tube-housing and includes a releasing element configured to bring an anti-free-flow mechanism of the tube-housing into a disengaged state which allows fluid to flow through the flexible tube, when the tube-housing is attached to the pumping mechanism, wherein said releasing element is further adapted to automatically disengage an anti-free-flow override mechanism, which anti-free-flow override mechanism is engageable when said housing is detached from the pump, said override mechanism being configured to, when engaged, mechanically latch the anti-free-flow mechanism in a non-obstructing state allowing fluid to flow through the tube while said housing is detached from the pump. - View Dependent Claims (15, 16, 17)
