Shirt-pocket medical alert device

A shirt-pocket sized medical alert device comprising:

• a separable housing sized and shaped to be carried unobtrusively by a user in a shirt pocket, for example, and to have an original, predetermined orientation on the user, the housing including a cover and a receptacle,
• a tilt activated alarm within the receptacle comprising:
• alarm means,
• power source means,
• tilt actuated circuit means, and
• electrically conductive conduit means connecting the alarm, power and tilt activated switch means, defining a tilt actuated circuit,
• whereby the alarm means is activated when the circuit is tilted and moved sufficiently from its original, predetermined position, for example when the user falls upon suffering a heart attack;
• said tilt activated switch means comprising:
• a cylindrical carrier spanned by an electrically conductive plate defining a first conductor and including a cone-shaped second conductor having a leading edge contacting the carrier and spaced a predetermined distance from the plate, a bottom end defining a tip and diverging electrically conductive side walls between the tip and leading edge,
• an insulator of predetermined thickness between the plate and the cone, and
• an electrically conductive flowable substance held in the cone tip when the housing is in the original predetermined orientation, the flowable substance of predetermined thickness sufficient to span the distance between the plate and the cone leading edge.
