<p>The need for means available to bedridden or other nonambulatory persons to summon assistance when required, is well known. Often such patients do not have the necessary vocal strength or muscular ability to summon attendant personnel without the aid of electrically operated audio or visual signalling devices. Further, such devices permit the personnel to be located some distance from the patient and yet be readily available when the signal is given. It is well known to provide switches near the patient for manual operation to initiate the activation of such signalling devices. In this invention, a signalling device consisting of a magnetic glass reed switch and magnet are separately encased in rectangular acrylic boxes. The boxes are adhered to the skin above the patient's brow using double-faced foam adhesive The signalling device is operable solely by furrowing the brow and requires minimal physical ability or manual dexterity.</p>
