Abstract
Inverted peristaltic pumps and related apparatus/methods wherein one or more compressible pump tubes are formed or mounted on a core member and one or more tube compressing members move about the core member so as to compress the tube(s) and propel a fluid through the tube(s). The core member may be removable and the pump tube(s) may be pre-mounted on the core member to form a disposable or reusable tubing cartridge. The core member or tubing cartridge may be easily inserted into and removed from the pump. In some embodiments troughs or grooves may be formed on the core member and the tube(s) may be disposed in such troughs or grooves.
Claims17
A peristaltic pump device comprising:
- an inner core member having an outer surface;
- a generally tubular fluid conduit having a lumen that extends longitudinally therethrough, said fluid conduit being positioned on and extending at least partially around the outer surface of the core member;
- an outer compression member positioned radially outside of the inner core member, said outer compression member being movable at least partially around the outer surface of the core member causing peristaltic compression of the fluid conduit so as to propel fluid through the lumen of the fluid conduit.
