Apparatus for pumping and dispensing a nutrional substance enterically along a conduit comprising a support structure, an electrically driven pump on said support structure, said pump comrpising a plurality of actuators which are movable along a fixed path of travel to actuate said conduit to thereby pump said nutritional substance along said conduit, a pressing member, pivotal means pivotally mounting said pressing member on said support structure for pivotal movement between an operable position and a non-operable position, said pressing member having a generally circular section, when said pressing member is in said operable position said circular section being spaced from said path of travel of said rollers a distance less than the outer diameter of said conduit such that the part of the conduit between said circular section and said path of travel of said rollers is squeezed and collapsed to effect a pumping action along said conduit, when said pressing member is in said non-operable position said circular section being spaced from the path of travel of said rollers a distance at least as great as the outer diameter of said conduit such that said conduit can be inserted and removed from between said pressing member and said rollers, and actuating means mounted on said base support and connected to said pressing member such that operation of said operable means pivots said pressing member about said pivotal means between said operable and said non-operable position, said actuating means comprising a manually operable control member to pivot said pressing member between said operable and non-operable positions.
