A device and method for enterally hydrating a patient, such as a paralyzed or limited upper body mobility patient with a functional gastrointestinal system who is nonetheless incapable or not fully capable of drinking unassisted. Here fluids are provided by a suspended semi-flexible container with graduation markings to allow for convenient estimation of fluid use, an upper open and closeable cap to allow the container to be refilled, and a lower fluid conducting tube that terminates in a mouthpiece, which contains a fluid valve formed from at least one slit in an elastic material. Patient mouth force on the valve causes the slit to enlarge, thus enabling fluid to flow into the patient.
