  • Publication number: 20100042062
    Abstract: An absorbent article includes a breathable backsheet material layer. At least a part of the layer includes a polymeric material exhibiting a discontinuous change in free volume in response to any of the following conditions or variables: liquid contact, the presence of certain ions, temperature and/or pH. One example of such polymeric materials is side chain liquid crystalline polymers which are able to undergo a phase transition between an isotropic phase and a nematic phase. The discontinuous change in free volume involves an abrupt change of the permeability of the breathable material layer.

    Abstract: A method for assisting a caregiver in determining when to select a next generation product for facilitating toilet training. The method includes the steps of providing information to a caregiver about a second absorbent product, such as a next generation product, while the caregiver is using a first absorbent product in conjunction with a child. The child, for instance, may not have started toilet training or may be in the process of toilet training. Based upon a behavioral or wetness characteristic of the child, recommendations are made to the caregiver when it is time to switch to the next generation product to facilitate toilet training. For instance, in one embodiment, the method may include comparing a wetness characteristic of the child with a readiness target. Once the readiness target is met, a recommendation may be made to the caregiver to switch to a product that includes a toilet training feature not present in the product currently being worn by the child.

The system includes two or more than two electrodes that are supported in a spaced apart relationship and a liquid permeable substrate between the electrodes that lacks or has a low capacity for holding or storing liquid. In the event of liquid leakage, an electrical bridge connecting the electrodes can be formed by the liquid, and before the product becomes saturated liquid can freely drain from the permeable substrate and disconnect the electrodes. Upon further liquid leakage, electrical connection between the electrodes can be reformed indicating multiple liquid leakage events. In the situation where the sanitary product becomes saturated and liquid is prevented from draining from the permeable substrate, the electrical connection will continue, indicating that the sanitary product requires changing.

The leakage warning system is located along the outer perimeter of the absorbent article. Fluids activate the leakage warning system. Thus, when fluids reach the outer perimeter of the absorbent article, the leakage warning system is activated. Once activated, the leakage warning system provides a warning signal that fluids have reached the edge of the absorbent article. In one embodiment, the leakage warning system is a liquid-activated band. Once activated, the band provides a temperature-change sensation to the user to signal that the fluids have reached the edge of the absorbent article and thus warns a user of possible leakage before it actually occurs.

  • Publication number: 20090112172
    Abstract: The subject of this patent pending idea, the AUDIO ALERT DIAPERS, consist of SEVERAL INNER LAYERS OF VARYING MATERIAL TYPES. Some for absorbancy and the remaining layers present serve as conduction contact area(S), so when moisture is present, these areas act as poles of a switch to activate a musical circuit. The conducting layers are separated by absorbant material, so that only moisture activates the audio. The purpose is to signal a listener when ample/excessive moisture is present. In summary, the diaper contains moisture until and excessive amount is present and alerts a listener. At the end of the said disposable diaper's absorbancy, a deactivation pull tab will disable the audio produced by the circuit.

  • Patent number: 7522061
    Abstract: The disclosure describes an external sensor attached to an undergarment worn by a patient that detects voiding information. The sensor stores the voiding information in a voiding log and transmits the voiding log to an external device. The external device includes a user interface that displays the voiding log to the patient for review. The patient may correct any incorrect voiding information that was logged in error or due to a non-voiding event. A user, such as a clinician or the patient, may use the voiding information to diagnose a condition of the patient. In addition, the voiding information of the voiding log may be used by the user to adjust a stimulation therapy or the external device to automatically adjust stimulation therapy. The undergarment may be disposable or washable after patient use.

  • Publication number: 20090099539
    Abstract: Potty training liners are a comfortable, child sized, absorbent liner, with a concave center and an expandable, flexible bottom to allow rapid flowing urine collection and retention. The Liner has unique absorbent collapsible side walls with an unobstructed center containing superabsorbent for quick pooling of urine. The liner is adhered to the inside of the child's underwear with a thick adhesive strip on the bottom outer portion of the liner. The Liner is soft and flexible, and does not have the feel of a diaper. It is a unique stop-gap solution for children progressing from pull-on diapers to unprotected underwear. The purpose of the liner is for training, and short term emergency “accident” protection, as opposed to long term wearable protection.

  • Publication number: 20090062756
    Abstract: A signaling device for garments is disclosed. The signaling devices, for instance, may be attached to an absorbent article containing a wetness sensing system. In particular, the signaling device may be configured to emit an audible and/or visible signal when a conductive fluid is sensed in the absorbent article. In accordance with the present disclosure, the signaling device is designed based upon anthropomorphic data so that the signaling device can fit within the small of the back of a wearer while minimizing discomfort. The signaling device can also be made from various materials that provide some protection to the internal components of the signaling device while also minimizing discomfort.

  • Patent number: 7498478
    Abstract: A method of detecting the presence of an insult within an absorbent article is disclosed. An electrical property is monitored and the electrical property is compared to a wet/dry threshold value to determine either a wet characteristic or a dry characteristic of the article. If a dry characteristic, then a first and possibly a second test are applied. If a wet characteristic, then the second test is applied. The electrical property is compared to a first threshold value and a second threshold value is set based upon the function of the comparison. A change in the electrical property of the article is monitored to determine if the electrical property has stabilized after activation of an insult alarm.
