ABSTRACT:
A device for teaching a patient to keep his lips closed, to combat dribbling, has a sensor electrode (12,22,46) for insertion between the lips, and an electrical detector (G1) and indicator (30) to indicate cessation of contact with at least one lip. The patient is thus reminded to keep his lips closed.
In one form, there is a secondary electrode (26) attached to a remote part of the patient's body, the detector detecting when an electrical circuit through the body is broken by the sensor electrode falling from the lips. In another form, the sensor electrode (46) is upwardly hooked (50) to contact the upper lip, and the detector detects absence of electrical contact between sensor electrode and a frame (32) hooked behind the lower lip.
