Cueing aid for prenatal breathing control

An apparatus for producing sensory cues for use by an expectant mother to synchronize her breathing to comprising:

• (a) first electrically energizable cueing means for producing a first sensory cue;
• (b) second electrically energizable cueing means for producing a second sensory cue;
• (c) electronic sequencer means for cyclically and alternately energizing said first and second cueing means, said sequencer means being capable of producing a plurality of manually selectable time patterns of cyclical and alternate energization of said first and second cueing means, at least one of which said time patterns having a duty cycle which varies automatically in a pre-determined fashion;
• (d) means for manually selecting a desired one of said plurality of patterns;
• (e) means for manually starting and stopping said sequence of alternate energization of said first and second cueing means;
• and
• (f) counter means for measuring and displaying the elapsed time between successive starting actuations of said starting and stopping means, said counter means including a counter responsive to first and successive odd actuations of said manual starting and stopping means in
• (i) displaying an accumulated count proportional to elapsed time,
• (ii) clearing said counter to zero, and
• (iii) accumulating a new count proportional to elapsed time.
