Device for volitional swallowing with a substitute sensory system
First Claim
1. An automatic stimulation controller device that cycles on and off to initiate and maintain vibro-tactile stimulation to induce swallowing during the day and/or night to provide saliva control by swallowing, the automatic stimulation controller device comprising:
- a vibro-tactile stimulator configured to initiate vibro-tactile stimulation of a throat area of a subject;
an automatic timing circuit in communication with the vibro-tactile stimulator, the automatic timing circuit configured to initiate vibro-tactile stimulation of the throat area of the subject by the vibro-tactile stimulator at an adjustable time interval, the automatic timing circuit comprising;
an oscillator configured to output a clock signal;
a programmable timer configured to receive the clock signal and to generate a first output pulse responsive to the clock signal, wherein the clock signal is adjustable to control the adjustable time interval of between about 1 minute and about 5 minutes; and
an adjustable timer configured to provide a second output pulse responsive to the first output pulse of the programmable timer, the second output pulse configured to initiate the vibro-tactile stimulation, wherein the second output pulse is adjustable to allow for setting the duration of stimulation between about 1 second and about 10 seconds, wherein the automatic stimulation controller device is configured to be adjusted to different intervals and durations of stimulation, wherein the vibro-tactile stimulation is configured to be adjusted to stimulation rates of between about 40 Hz and about 70 Hz; and
a control mechanism configured to also cause the vibro-tactile stimulator to initiate the vibro-tactile stimulation upon volitional input from the subject, the control mechanism comprising a switch configured to enable the device to switch between an automatic mode utilizing the automatic timing circuit and a volitional mode utilizing the control mechanism.

Abstract
A device for volitional swallowing with a substitute sensory system comprises a band 101 wrapped around the neck with a vibrator 102 positioned over the larynx. Upon activation by a button 103 on a spoon 104 held by an operator, such as the subject 105, the vibrator 102 moves and vibrates the larynx. The patient 105 initiates the sensory stimulation immediately prior to the patient'"'"'s own initiation of a swallow by viewing on a display screen 106 a movement feedback signal 107, possibly from a piezo-electric sensor 108 also contained in the band 101 which will also be displayed on the display screen 106. The signal 109 from the switch device initiating sensory stimulation will be presented on the same display screen 106 for the patient 105 and trainer to observe when the button or switch 103 is activated for sensory stimulation in relation to the onset of the swallow.
