ABSTRACT:
Apparatus for administering oral fluid from a reservoir (60) to a patient comprises: a chamber (10,30) suitably formed by connection of a mouthpiece (30) to be held adjacent the gums and/or teeth and a nipple (10) or diaphragm (310) at the mouthpiece rear for tongue activation, with fluid inlet and outlet openings (34,12) formed respectively in the former and latter; a tube (40) connected between the chamber inlet opening and reservoir; and a fluid flow control valve (50) connected in the tube, such valve suitably having a cylinder housing (51) with inlet and outlet ports (54,53) at its ends and a piston valve member (55) freely reciprocable therein a clearance fit to close and open the outlet port. The valve is preferably effectively symmetrical with a ball piston (55) reciprocable also to close and open the inlet port. The mouthpiece is preferably transversely ovate and/or forwardly dished to accommodate to its oral location, and also reticulate (32) and/or formed with peripheral incursions (33) to facilitate mouth breathing. The nipple is preferably upwardly inclined towards the palate with the outlet opening in its underside, and is suitably flattened with downward curving or chamfering towards its free end.
