Patent Application
20220151839
The present disclosure generally relates to diapers. More particularly but not exclusively the present disclosure relates to a diaper with a collection pouch.
Diapers include both disposable baby diapers and adult diapers. Diapers can be necessary for adults with various conditions, such as incontinence, mobility impairment, severe diarrhea or dementia. A diaper is a type of underwear that allows the wearer to defecate or urinate without the use of a toilet, by absorbing or containing waste products to prevent soiling of outer clothing or the external environment. When diapers become soiled, they require changing, generally by a second person such as a parent or a caregiver. Diapers have a facing layer to be brought into contact with the wearer's skin, an absorbent panel adjacent thereto, and a water-impervious or a water repellant outer layer. Following defecation, prolonged contact of feces with the wearer's skin may have adverse health consequences such as rashes or infections. For caregivers, changing the soiled diapers of adult patients poses many practical challenges as the task is usually extremely messy with fecal matter spilling out of the diapers and onto the sheets of the patient's bed. The ordeal worsens with patients suffering with sever diarrhea and other digestive issues.
An object of the present disclosure is to provide a diaper with a collection pouch.
In accordance with an aspect of the present disclosure, there is provided a diaper comprising: a bottom layer defining a top surface and an opposite outer surface and comprising an absorbent core therebetween; and a top layer mounted to the bottom layer about a peripheral border thereof defining a top layer area delimited by the peripheral border overlying the top surface and being unconnected to the bottom layer, the top layer area, the top surface and the peripheral border defining a pouch therebetween, the top layer area defining a body contacting surface and an opening for providing access to the pouch, wherein when the diaper is worn by the user, the opening is positioned about the anus of a user for providing for fecal matter to enter the pouch during defecation.
In an embodiment, the opening is surrounded by a border. In an embodiment, the top layer area comprises a lip defining the border and upwardly protruding therefrom and circumscribing the opening. In an embodiment, the lip portion is formed by rolled up material. In an embodiment, the top layer comprises a region of flexible and resilient material for upwardly protruding the border therefrom. In an embodiment, the border is so configured and sized as to be positioned within the intergluteal cleft.
In an embodiment, the top layer is spaced from the top surface of the bottom layer. In an embodiment, the top layer has a top layer surface area and the bottom layer has a bottom layer surface area, the top layer surface area being smaller than the bottom layer surface area. In an embodiment, an underside surface interfacing with the top layer of the bottom surface, the peripheral border defining an inner contour surface at a junction of the underside surface and the top surface of the bottom layer. In an embodiment, at least one of the underside surface, the top surface of the bottom layer and the inner contour surface comprises impermeable material.
In an embodiment, the diaper further comprises a closure for closing the opening following defecation within the pouch. In an embodiment, the closure comprises an adhesive strip of material. In an embodiment, the closure comprises a drawstring fitted within a border surrounding the opening, the border defining border apertures for opposite ends of the drawstring to protrude therefrom for being pulled to close the opening.
In accordance with an aspect of the present disclosure there is provided a diaper kit comprising a plurality of any one of the above diapers.
Other objects, advantages and features of the present disclosure will become more apparent upon reading of the following non-restrictive description of illustrative embodiments thereof, given by way of example only with reference to the accompanying drawings.
In the appended drawings:
Generally stated and in accordance with an aspect of the present disclosure, there is provided a diaper comprising a bottom layer and a top layer mounted thereto. The bottom layer defines a top surface and an opposite outer surface and comprises an absorbent core therebetween. The top layer is mounted to the bottom layer about a peripheral border thereof. The top layer defines a top layer area delimited by the peripheral border overlying the top surface and being unconnected to the bottom layer. The top layer area, the top surface and the peripheral border define a pouch therebetween. The top layer area defines a body contacting surface and an opening for providing access to the pouch. When the diaper is worn by the user, the opening is positioned about the anus of a user for providing for fecal matter to enter the pouch during defecation.
With reference to
Referring to
Each lateral side 16A and 16B has an inwardly curving edges 22A and 22B respectively. Inwardly curved edge 22A is positioned between lateral end edges 21A and 23A, respectively positioned near edges 12 and 14. Similarly, inwardly curved edge 22B is positioned between lateral end edges 21B and 23B, respectively positioned near edges 12 and 14.
The diaper incudes a rear portion 24 (generally formed between later end edges 21A and 21B), a mid portion 26 (generally formed between inwardly curved edges 22A and 22B) and a front portion 28 (generally formed between lateral end edges 23A and 23B). Tabs 30 extend from the lateral edges 21A and 21B for being fastened to the outer side 20 of the front position 28 thereby attaching the diaper around a user's waist and providing for the rear and front portions 24 and 26 to cover the rear and front of the wearer with the mid portion 26 extending therebetween. Of course, belt loops instead of tabs 30 may be used. The inwardly curving edges 22A and 22B are designed to fit around a user's legs and thereby provide a snug fit.
As shown the inner side 18 defines an opening 32 at the mid portion 26 providing access to a pouch 34.
The diaper 10 includes a top layer 36 with a bottom layer 38 mounted thereto about a peripheral border 40 thereof defining the pouch 34 therebetween.
The bottom layer 38 includes a top surface 42, an opposite outer surface 44 with an absorbent core 48 therebetween. The surfaces 42 and 44 and the core 48 are fused together to form a single layer laminate 38. The outer surface 44 includes elastic material 50 causing the diaper to have a c-shaped curved body form between edges 12 and 14.
The top layer 36 defines a top layer area 52 delimited by the peripheral border 40. The top layer 36 is unconnected to the bottom layer 38 and as thus loosely overlies the top surface 42 of the bottom layer 38. The opening 32 is formed in the top layer area 52 providing access to the pouch 34. The top layer 36 includes an undersurface 55.
The undersurface 55 of the top layer 36 and the top surface 42 of the bottom layer 38 are connected at a contour portion 57 near the border 40 defining an inner contour surface 57′. The pouch 34 is thus delimited by surfaces 42, 55 and 57′. The bottom layer top surface 42 defines the bottom border to the pouch 34. The top layer undersurface 55 defines the top border of the pouch 34. The contour portion inner surface 57′ defined the peripheral border of the pouch 34 and is at a junction between the underside surface 55 and the top surface 42 of the bottom layer 38. In an embodiment, surfaces 42, 55 and 57′ are made of impermeable material.
The top layer 36 has a smaller surface area than the bottom layer 38 and as such when mounted thereto at its border 40, the top layer area 52 is stretched causing it to rise upwardly and be spaced above the top surface 42 of the bottom layer 38 bringing the opening 32 upward towards the wearer. The foregoing is further aided by the elastic material 50 which causes the o-shaped configuration of the bottom layer 38. The foregoing configuration and the disposition of the opening 32 provides for positioning the opening 32 about the anus of the wearer for fecal matter to be guided therethrough during defecation.
A lip 54 circumscribes the opening 32. The lip 54 is provided by rolled up material 56 upwardly protruding from the top layer area 52. The lip 54 may be so configured and sized so as to be positioned in the intergluteal cleft. The configuration of the diaper 10 due to the differential in the surface area between the top 36 and bottom 38 layers provides for urging the lip 54 about the anus of the wearer for providing to guide fecal matter through the opening 32 and into the pouch 34 during defecation.
The fecal matter thus fills the pouch 34 formed between the top and bottom layers, 36 and 38, respectively. The lip 54 thus forms a border that substantially blocks spillage of fecal matter onto the top layer surface area 52.
The diaper 10 provided for the focal matter to not be in direct contact with the skin of the wearer post defecation and prior removal of the diaper. Moreover, during removal of diaper 10 following defecation, there is less risk of the caregiver coming into direct contact with the fecal matter as it is all or mostly in the pouch 34. The diaper 10 may be provided with a closure for closing the opening 32 post usage to further avoid outward spillage.
In an embodiment, the closure includes a strip of adhesive material 58 shown in
The diapers 10 and 10′ can be made of a variety of suitable materials and designed in a variety of suitable configurations within the context of the present disclosure.
