A pump apparatus such as a stomach pump or the like having a variable volume pumping chamber in the form of a resiliently flexible bulb with a one way flow check valve disposed within the bulb to preclude backflow therefrom, and a second check valve downstream of the resilient bulb, preferably within a reservoir to preclude backflow from the reservoir to the pumping chamber and to contain pumped matter within the reservoir.

A stomach pump or the like comprising: a resiliently flexible bulb means enclosing an interior space and having an outlet and an inlet communicating between said interior space and the exterior of said bulb means; first one-way flow check valve means disposed in fluid flow communication with said inlet and operable to preclude material movement from said interior space via said inlet; first connector means disposed adjacent said outlet; a remote reservoir means for receiving material therewithin and including a second connector means disposed in fluid flow communication therewith to permit movement of material into said reservoir means; selectively releasable means connecting said first and second connector means to permit material to move from said interior space of said bulb means into said remote reservoir means; and said reservoir means including second one-way flow check valve means disposed in fluid flow communication with said second connector means and operable to preclude movement of material from within said reservoir means via said second connector means.
