Sensor devices and systems for monitoring the basic needs of an infant comprising feeding, sleeping, and/or voiding (urinating and/or defecating) are described herein.

The invention provides an absorbent article comprising an indication means for indicating the presence of bodily exudates, the indication means comprising a color-changing indication means, wherein the absorbent article and the indication means form one integral unit, the article further comprising a indication device, which comprises a housing and a connection means, such that the indication device can be attached to the absorbent article and be detached from the absorbent article, wherein the indication device comprises a color sensor.

A diaper state change notification device has a power source, a micro controller capable of generating a notification, a wireless communications chip, and one or more sensors incorporated in the device or coupled thereto, characterized in that the notification device is attached to or otherwise embedded within a diaper and generates and sends a notification to a monitoring entity upon sensor detection of a diaper state change from a fresh diaper state to a soiled diaper state.

A disposable diaper having a first sheet of viscose fiber material disposed against a child's skin, an acquisition and diffusion layer (ADL) interposed over top of the first sheet of viscose fiber, a coating layer of tissue fiber interposed over top of the ADL layer, an absorbency core layer interposed over top of the coating layer, a permeable layer of polymer film interposed over top of the absorbency core layer, and a second sheet of viscose fiber material overlaid over top of the permeable polymer film layer, the second sheet functioning as the exterior sheet of the disposable diaper.

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

An incontinence assist appliance for a user comprises an envelope including a surface, such as an upper outside surface, for contact with the user. A removable bladder is receivable within the envelope and includes a port for attachment of a catheter which passes through an opening in the outer envelope. The bladder contains a urine absorbing substance so that it avoids spills of liquid urine. The envelope may be formed as a wearable garment. A pair of trousers incorporating the appliance in each leg is also provided.

An absorbent article comprises an absorbent core sandwiched between a topsheet and a backsheet. The article defines a front portion, a back portion and a crotch portion. The absorbent core comprises an absorbent component enclosed by a core cover comprising an upper and a lower side, and the core is formed with a sealing arrangement for joining the upper and lower sides comprising two channel sealings extending along an longitudinal axis in the crotch portion and defining a first channel sealing width and a second channel sealing width, respectively. The front portion of the core is formed with a recess defining a depth extending from a front edge of the core and into the front portion. A distance is defined between said front edge of the core and a front edge of each channel sealing, such that the ratio of the depth and the distance is within the interval 0.05-0.8.

An absorbent article comprising an absorbent core having a longitudinally extending channel-forming area and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid a channel is formed along the area substantially free of absorbent material.

The present invention relates to absorbent articles comprising at least one attachment region for securing a wearable sensing device and further comprising visible placement indicia aligned with the attachment region wherein the visible placement indicia aids the placement of the wearable sensing device on the absorbent article. The present invention further relates to a system comprising the absorbent article and the wearable sensing device.

The present invention further relates to a method for manufacturing an absorbent article comprising visible placement indicia aligned with a wetness indicator and/or attachment region.

A process of making an absorbent article is disclosed. A liquid permeable topsheet web extending substantially continuously in a machine direction a backsheet web, and an intermediate layer are provided. The topsheet web has first and second surfaces. The backsheet web extends substantially continuously in the machine direction. The intermediate layer has a first and second surface. The topsheet and intermediate layer are aligned in a face to face relationship such that the second surface of the topsheet in in contact with the first surface of the intermediate layer and simultaneously mechanically deformed which combines the topsheet with the intermediate layer. The topsheet web and intermediate layer are nested together such that a majority of the three-dimensional protrusions formed in the topsheet web coincide with and fit together with a majority of the three-dimensional protrusions formed in the intermediate layer to provide a topsheet/intermediate layer laminate web having three-dimensional protrusions.
