Apparatus for delivering liquid from a container to the mouth of a patient on demand comprises a flexible tube having first and second ends, the first end being insertable into the container, and a rigid tube having a first end attachable to the second end of the flexible tube and a second end attachable to a flexible drinking straw. The rigid tube has a first portion terminating in the first end of the rigid tube and a second portion extending laterally from the first portion in cantilever fashion so as to locate the second end of the rigid tube laterally spaced from the first portion, whereby the patient, by only a slight head movement, can grasp the straw and obtain liquid from the container through the flexible and rigid tubes and the straw, without assistance from any other person.
