Peristaltic pump with ganged tubes
View Patent ↗A pump having a rotary portion which compels the movement of a fluid by peristaltic compression of resilient tubing containing the fluid includes a tube component having a plurality of adjacent resilient tubes, with a web interconnecting the adjacent resilient tubes. The web may be offset from the centerline of the tubes so as not to degrade the compressibility of the tubes.
1. In a pump having a rotary portion which compels the movement of a fluid by peristaltic compression of resilient tubing containing the fluid, a tube component comprising the following:
a plurality of adjacent resilient tubes; and
an offset web interconnecting the adjacent resilient tubes, wherein the resilient tubes and the offset web are integrally formed, and each of the resilient tubes has a cross-sectional centerline occurring in a common plane and the offset web only interconnects the resilient tubes in an area outside of the common plane.
2. A tube component in accordance with claim 1 , wherein the resilient tubes are fabricated from an elastomeric plastic material.
3. A tube component in accordance with claim 1 , wherein the rotary portion of the pump includes a rotary area of pump operation, and the web is outside the rotary area of pump operation.
4. A method of assembling a pump having a rotary portion which compels the movement of a fluid by peristaltic compression of resilient tubing containing the fluid comprising the following:
providing a plurality of adjacent resilient tubes; and
interconnecting the adjacent resilient tubes with an offset web, the resilient tubes and offset web being integrally formed, and wherein each of the resilient tubes has a cross-sectional centerline occurring in a common plane, the rotary portion of the pump includes a rotary area of pump operation, and the resilient tubes are only interconnected with the offset web in an area outside of the common plane and in an area outside the rotary area of pump operation.
5. A method in accordance with claim 4 , wherein providing a plurality of adjacent resilient tubes comprises providing resilient tubes fabricated from an elastomeric plastic material.
