Abstract
A warning alarm diaper device including a moisture detecting device and a warning alarm device. Preferably, the diaper and moisture-detecting device are disposable, and the warning alarm device is reusable.
Claims20
A warning alarm diaper device, comprising:
- a disposable diaper having an inner ply and an outer ply with an absorbing layer disposed between said inner ply and said outer ply;
- a disposable detecting device attached to an upper surface of said inner ply of said disposable diaper, said detecting device comprising:
- a first pair of wires provided with an electrical insulation layer along a length thereof, said first pair of wires having a pair of wire conductors having uninsulated exposed ends;
- a first absorbent layer covering each of said uninsulated exposed ends of said first pair of wires, said absorbent layer being separate pieces of absorbent tissue paper folded around each of said uninsulated exposed ends of said first pair of wires, said first absorbent layer maintaining said uninsulated ends of said first pair of wires spaced apart a predetermined distance;
- a second absorbent layer covering said first absorbent layer, said second absorbent layer being a piece of tissue paper;
- an electrical insulating support layer provided over said second absorbent layer and configured to connect together and support said exposed ends of said first pair of wires, and connect together and support said first absorbent layer and said second absorbent layer as an unit, and electrically insulate a user's skin from an electrical circuit when established by moisture or wetness existing between said uninsulated exposed ends of said first pair of wires, said electrical insulating support layer being electrical insulating tape configured to extend beyond edges of said second absorbent layer and attach said detecting device as said unit to said upper side of said inner ply of said disposable diaper;
- and
- a contact adhesive layer provided on said electrical insulating support layer for securing said detecting device as an unit to said upper side of said inner ply of said disposable diaper, whereby moisture or wetness provided by a user's waste is absorbed into said absorbing layer of said disposable diaper and then passes through said absorbent layer and inner ply of said disposable diaper into contact with said detecting device, and then passes through said second absorbent layer and then said first absorbent layer of said detecting device underneath said electrical insulating support layer until reaching a sufficient level to allow an electrical circuit to exist between said exposed ends of said first pair of wires while protecting the user's skin against electrical exposure;
- a first electrical plug connection provided on an opposite end of said first pair of wires;
- and
- a reusable warning alarm device, comprising:
- a case;
- a battery disposed within said case;
- an electrical audio warning signal generating device disposed within said case and electrically connected to said battery,
- a second pair of wires electrically connected in an electrical circuit to said battery and said electrical audio warning signal generating device, said second pair of wires provided with a second electrical plug connection to releasable connect with said first electrical plug connection of said detecting device, said battery and said electrical audio warning signal generating device being electrically connected to said second pair of wires to provide an open electrical circuit when said uninsulated ends of said pair of wires are dry and a closed electrical circuit when said uninsulated ends of said pair of wires are wet, whereby an audio warning signal is generated to indicate said diaper is soiled, said case including a blinking light to indicate said open electrical circuit is operational readied to drive said warning signal when said open electrical circuit is closed.

A warning alarm diaper device, comprising:
- a diaper having an inner ply;
- a moisture-detecting device attached to an upper side of said inner ply of said diaper, said detecting device comprising:
- a pair of wires provided with an electrical insulating layer, said pair of wires having uninsulated exposed ends;
- a first absorbent layer surrounding said uninsulated exposed ends of said pair of wires, said first absorbent layer maintaining said uninsulated ends of said pair of wires spaced apart a predetermined distance;
- a second absorbent layer covering said first absorbent layer;
- an electrical insulating support layer covering said second absorbent layer and configured to electrically insulate a user's skin from an electrical circuit when established between said uninsulated exposed ends of said pair of wires, said electrical insulating support layer being larger in area relative to said second absorbent layer and shaped so as to extend beyond all edges of said second absorbent layer to attach to said upper side of said inner ply of said diaper and prevent direct contact of said second absorbent layer, prevent contact of said first absorbent layer, and prevent contact of said uninsulated ends of said pair of wires with the user's skin;
- and
- a warning alarm device, comprising:
- a case containing a battery electrically connected to an electrical audio warning signal generating device, said battery and said electrical audio warning signal generating device being releasably electrically connected to said detecting device to provide an open electrical circuit when said uninsulated ends of said pair of wires are dry and a closed electrical circuit when said uninsulated ends of said pair of wires are moist or wet, whereby an audio warning signal is generated to indicate said diaper is soiled.
6 more elements
A warning alarm diaper system, comprising:
- a disposable diaper having an inner ply;
- a separate disposable moisture detecting device unit attached to an upper surface of said inner ply of said disposable diaper, said detecting device including a sticky back layer covered by a removable release liner, whereby the release liner can be removed for adhering said detecting device unit to said upper surface of said inner ply of said disposable diaper, said detecting device including an upper insulating support layer separating a user's skin from said detecting device unit device to protect a user's skin against electrical current when an electrical circuit with said detecting device is activated, said upper insulating support layer covering edges of said detecting device unit and provided with said sticky back layer to adhere said detecting device unit inside said diaper and configured to only allow moisture to reach said detecting device unit from the user's waste through passage of the moisture down into said diaper and then up underneath into said detecting device unit adhered to said diaper;
- and
- a separate reusable warning alarm device removably connected to said detecting device, said warning alarm device including a battery and an electrical audio warning signal generating device for energizing said electrical circuit within said detecting device, whereby said electrical circuit is open when said detecting device is dry and closed when said detecting device is moistened from said diaper portion located beneath said detecting device.
