The present invention is directed to a diaper warning alarm device. The diaper warning alarm device according to the present invention includes the combination of a diaper, a moisture-detecting device and an alarm device. Specifically, the detecting device can be a separate detecting device installed in or added to an existing diaper, or the detecting device can be constructed or assembled within or otherwise incorporated into the diaper. Further, the alarm device can be separate from the diaper or incorporated into the diaper during or after construction thereof. The diaper can be a reusable diaper (e.g. cloth or fabric diaper), or preferably is a disposable type diaper.
The diaper warning alarm device according to the present invention includes a detecting device for sensing moisture or wetness from the user's urine or liquid stool contained within the diaper, and a warning signal generating device such as an audio and/or light warning signal. In some embodiments, the diaper warning alarm device is disposed within the diaper or in proximity to the diaper, and in other embodiments, the diaper warning alarm device is a remote device separate from the diaper. In the remote warning alarm device embodiments, a transmitter device is provided in combination with the detector device incorporated in the diaper for activating the remote warning-signaling device. Optionally, the diaper warning alarm device is provided with a device to indicate that the diaper warning alarm device is turned on, or otherwise operational. For example, the diaper warning device can be provided with a red light that stays on (e.g. light emitting diode) or a blinking red light that turns on when the diaper warning device is turned on and operational.
The detecting device is provided within the diaper in a manner so as to sense the user's waste at the time the waste is discharged into the diaper. A preferred detecting device is a moisture-detecting device. In some embodiment, the detecting device is configured so that moisture from the waste is directly transferred or transmitted to the detecting device. In other more preferred embodiments, the detecting device is configured so that the moisture from the waste is indirectly transferred or transmitted to the detecting device. For example, in some embodiments the moisture for the waste must first enter into the thickness of the diaper, and then transferred to the detecting device. Specifically, the disposable diaper can be constructed with an inner ply to allow moisture to immediately pass there through into an absorbent middle layer with an outer protective or water impermeable outer layer to prevent moisture or waste to pass to the exterior of the diaper and contain same in the middle absorbent layer. The moisture in the absorbent middle layer then moves or is transferred through the layer and underneath the detecting device until reaching a bottom surface or absorbent layer or panel of the detecting device to then activate the detecting device by closing an electrical circuit therein. The moisture between a pair of spaced apart electrodes (e.g. exposed ends of pair of wires) closed the electrical circuit therebetween by carrying current and transferring electrons between the pair of spaced apart electrodes. The above-described indirect pathway for the moisture from the user's waste to the pair of spaced apart electrodes significantly prevents any electrical current reaching the user's skin and protects same.
A preferred detecting device includes an electrical insulating support layer configured to make contact with the user's skin when the detecting device is installed within the diaper. When installed, underneath the electrical insulating support layer is the pair of spaced apart electrodes. Preferably, the electrodes are wrapped or surrounded by a first moisture absorbent layer. More preferably, the first moisture absorbent layer is covered by a second moisture absorbent layer provided underneath and in direct contact with the inner ply of the diaper when the detecting device is installed within the diaper. In a preferred embodiment, the electrical insulating layer is made of an electrical insulating tape having a sticky back layer or contact adhesive layer provided on one side thereof. In a more preferred embodiment, the insulating tape is shaped and/or sized so as to extend past the edges of the first and second moisture absorbent layers to provide an electrical insulating seal with the inner ply of the diaper when the detecting device is installed within the diaper. In this manner the sticky back or contact adhesive layer of the tape secures the detecting device to the inner ply of the diaper, and also prevents moisture from the user's waste from making direct contact with either the first and second moisture absorbent layers and particularly direct contact with the pair of spaced apart electrodes requiring all moisture reaching the working components of the detecting device to first transfer through the middle absorbent layer of the diaper and then reach underneath the detecting device the second moisture absorbent layer, then first moisture absorbent layer, and then the pair of spaced apart electrodes.
The system of the present invention preferably includes a diaper, disposable detecting device, and a reusable alarm device. In this manner the diaper and detecting device are discarded when changing the diaper, and the alarm device is used with the new or fresh diaper and new or fresh detecting device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
A diaper warning alarm device 10 according to the present invention is shown in FIGS. 1-4 and 6-9.
The diaper warning alarm device 10 includes a diaper 12 and a warning alarm device 14. The diaper 12 can be a paper, fabric or cloth diaper, and preferably a disposable diaper.
The alarm device 14 is connected by a pair of wires 16 to a detecting device 18 as shown in FIG. 2. The pair of wires 16 is provided with a two-part electrical connector 20, for example, including a male connector portion 20a and a female connector portion 20b. The male connector portion 20a and the female connector portion 20b can be reversed in order from that shown. The two-part electrical connector 20 allows for the alarm device 14 to be removably connected to the detecting device 18.
The diaper 12 can be a reusable diaper, or more preferably a disposable diaper 12. For example, the diaper 12 includes a pair of tape connectors 22 for connecting a back panel 12b to a front panel 12a of the diaper 12. In another preferred embodiment of the diaper, an upper elastic waistband is incorporated at the top of the diaper instead of the tape connectors 22. In some embodiments, the detecting device 18 is part of or assembled as part of the construction of the diaper 12, and in a preferred embodiment, the detecting device 18 is add-on device so that the detecting device 18 can be applied to any existing type or variety of diaper. For example, the detecting device 18 is provided with a sticky-back layer with a release liner to allow the detecting device 18 to be adhered to the inside bottom portion of the diaper 12. This construction will be discussed in more detail below.
The detailed construction of the detecting device 18 is shown in FIGS. 2-5.
The detecting device 18 includes the pair of wires 16 having conductor wires 24a, 24b provided with an electrical insulation layer 17 and exposed ends 19a, 19b. The conductor wires 24a, 24b are surrounded or wrapped with absorbing layers 26a, 26b, respectively. The absorbing layers 26a, 26b are made of a moisture absorbing material such as paper, felt, cloth, cardboard, fabric, fiber, filament, sponge, foam or other suitable material capable of absorbing water and then supporting electrical current there through. A thick or heavy weight paper material is particularly preferred due to its low cost, high availability, and good to excellent performance. For example, a rectangular piece of paper is folded in half and then wrapped around each conductor wire 24a, 24b. The exposed ends 16a, 16b of the pair of wires 16 are spaced apart a distance D to provide an open circuit there between until the absorbing layers 26a, 26b become moist or wetted to an extent to provide a closed electrical circuit there between.
The conductor wires 24a, 24b and surrounding absorbing layers 26a, 26b are installed or placed on an insulating support layer 28, as shown in FIGS. 3 and 4. The insulating support layer 28 is made of an electrically insulating material such as a plastic or Mylar tape having a “sticky back” or contact adhesive layer 30. The absorbing layers 26a, 26b when dry adhere to the contacted adhesive layer 30 during construction or assembly of the detecting device 18. A second absorbing layer 32 is provided over and covers the first absorbing layers 26a, 26b and connects with the contact adhesive layer 30 at the edges thereof during construction or assembly of the detecting device 18. The remaining exposed portion or area of the contact adhesive layer 30 can be provided with a release layer or liner 34. In the embodiment shown in FIGS. 3 and 4, the release layer 34 is provided only around the perimeter of the edge of the insulating support.
In the embodiment shown in FIG. 5 the release layer 34′ is the same shape and size as the insulating support layer 28, and overlaps and covers the entire insulating layer 28′.
The warning alarm device 14 is also shown alone in FIGS. 6 and 7. The warning alarm device 14 includes a case 36 provided with a perforated area or plate 38 provided with a plurality of through holes for allowing an audio warning signal such as a bell, buzzer, tone or other warning noise to emanate through the case from the inside of the case to the outside. Alternatively, the perforated area 38 can be replaced with a single through hole cooperating with a noise or audio signal generating device 40, as indicated in the electrical circuit shown in FIG. 8. The backside of the alarm device 14 is provided with an optional switch 42 and an access door 44 having a screw fastener 46 for a battery 48 (e.g. AA, AAA, 9-Volt), as indicated in FIG. 8. Again, the switch 42 (e.g. slide switch) is optional, since the alarm device 14 can be disconnected from the detecting device 18 by two-part electrical connector 20, which connection and disconnection thereof can eliminate the need for a switch for the electrical circuit 50 shown in FIG. 8. An intermittent red blinking light 51 is provided on the front side of case 36, and connected into the electrical circuit 50 shown in FIG. 8. The operation of the red blinking light 51 indicates that the warning alarm device is operational when the switch 42 is closed, and the battery 48 is alive to power or drive the electrical circuit 50. If the read blinking light 51 does not turn on after closing switch 42, then battery 48 is dead and needs to be replaced.
In use, as shown in FIG. 9, the detecting device 18 is applied to the inner ply 52 of the diaper 12 by removing the release layer 34 and sticking the detecting device 18 in contact with the surface of the inner ply 52 of the diaper 12. The insulating support layer 28 is then in direct contact with the surface of the inner ply 52, and protects the skin S of the user from electrical contact or current between the conductor wires 24a, 24b when the circuit 50 (FIG. 8) is closed due to moisture or wetness. Specifically, the pathway for moisture or wetness from the user's waste is from around the outer edges of the insulating support layer 28 of the detecting device 18 and through the thickness of the diaper 12. Specifically, the moisture or wetness seeps into the absorbing layer 54 between the inner ply 52 and the outer ply 56 of the diaper 12. As the moisture or wetness penetrates into the absorbing layer 54 of the diaper 12 the moisture or wetness moves or flows inwardly from the edges of the detecting device 18 until reaching the second absorbing layer 32. After the second absorbing layer 32 is moisten or wetted, the first absorbing 26a, 26b then eventually become moistened or wetted. When there exists an adequate level of moisture in the first absorbing layers 26a, 26b located between the conductor wires 24a, 24b, an electrical current can begin to flow or exist there between. At this point, the electrical circuit, as shown in FIG. 8, is closed and the warning noise or audio signal generating device 40 is activated by the battery 48 generating a warning noise or audio signal from the alarm device 14. Optionally, the alarm device 18 can be provided with an additional control (e.g. slide switch or dial switch) to control or adjust the level of warning noise of audio signal being generated from the device 40. This warning noise or audio signal alerts the user and/or caregiver to change the diaper 12 due to the moisture or wetness indicating a soiled diaper.
The warning-signaling device 14 can optionally include a radio transmitter for activating a separate remote warning-signaling device to be located at a remote location (e.g. nurse's station, office, master bedroom).
SYSTEM
The present invention is also directed to a diaper warning alarm system. The system includes a reusable warning alarm device 14 in combination with a plurality of disposable detecting devices 18. For example, the pair of wires 16 and detecting device 18 are assembled as disposable units 16, 18, and are disposed of after a single use when disconnecting the two-part electrical connector 20. Preferably, the disposable units 16, 18 are packaged to maintain cleanliness (e.g. cardboard or plastic container), or can be individually wrapped, or even sterilized in a disposable wrapper. The disposable units once removed from the packaging are applied or installed in the bottom portion of a diaper 12, preferably a disposable diaper, readied to be put on a user. Preferably, the pair of wires 16 extend up and out of the front panel 12a of the diaper 12 shown in FIG. 1, or can be positioned out the side or out of the back panel 12b of the diaper 12 depending on the particular user activity. Before or after the diaper 12 is put on the user, the warning alarm device 14 is connected to the detecting device 18 by the two-part electrical connector 20. The warning alarm device 14 can be placed in a user's pocket, (e.g. robe pocket), or can be connected or fastened to the diaper 12 or user in some manner (e.g. hook and loop type fastener, mechanical fastener, tape or other connector). After the warning alarm signal goes off, the user or caregiver changes the diaper 12 with a new diaper fitted with a new disposable detecting unit 16, 18.
