ABSTRACT:
A device for administering oral fluid to a patient from a container (18) has a nipple (14) connected to the container (18) by a tube (16). The nipple (14) is held on the patient's tongue. A valve (22) opens in response to the patient sucking or pressing the nipple to initiate a flow of fluid in the tube (16). A detector (92) responds to this flow and switches on a peristaltic pump (90) for a period determined by the setting of a controller (102) to deliver positively a suitable bolus of 2 to 6 ml to the patient. To give the patient time to swallow the bolus, the detector (92) is inhibited for a predetermined delay period after termination of the bolus and over the same delay period, the tube (16) remains pinched or clamped.
