Description

A diaper having a stool detection function, and a stool detection device {DIAPER FOR SENSING URI AND FECES, AND URI AND FECES SENSING DEVICE}

The present invention relates to a diaper and a toilet detection device, and more particularly, to a diaper having a urine detection function for detecting a change in the diaper caused by urine and feces, and a toilet detection device usable in connection therewith.

In general, diapers may be classified into band-type diapers, panty-type diapers, pad-type diapers, etc. according to their use, and may be classified into infant diapers, adult diapers, and the like, according to wear targets. Disposable diaper products are mainly used for receiving, isolating, and disposing of body secretions from babies and adult incontinence. The diaper may be composed of three layers: a lining layer, an absorbent layer for absorbing feces, and an outer cover for preventing feces from leaking out of the diaper.

Some of these diaper products have a function of detecting whether the wearer of the diaper is currently urinating without taking off the diaper by using a sensing wire provided in the diaper. However, the conventional diaper capable of detecting a bowel movement is located inside the absorbent layer so that the sensing wire does not directly contact the skin, or is located between the absorbent layer and the lining layer, so that the diaper does not come into direct contact with feces.

Such a conventional diaper detectable for defecation assumes that the moisture contained in the feces can pass through the lining layer of the diaper and reach the sensing line, but the moisture contained in the feces passes through the lining layer and reaches the sensing line. The quantity is very small. For this reason, a conventional diaper capable of detecting a feces may be sufficient to detect urine or feces with a high water content, but has insufficient performance to detect feces with a low moisture content. Therefore, there is an urgent need for research on diapers and sensors that can fully detect feces with low water content.

On the other hand, when the detection line is disposed close to the inner surface of the lining layer of the diaper in contact with the human skin for detecting urine and feces, the toilet detection device for detecting urine and feces through the detection line is also close to the inner surface of the lining layer of the diaper. Since it should be positioned so that a part of the toilet detection device comes into contact with the skin, it may cause discomfort to the diaper wearer. In addition, as the detection wire is disposed closer to the inner surface of the lining layer of the diaper, it becomes difficult to electrically connect the toilet detection device to the detection wire, and the electrical connection between the toilet detection device and the detection wire is poor, so that the toilet cannot be accurately detected. can Publication No. 10-2018-0124060 (published on November 20, 2018) discloses an absorbent article.

The present invention can detect not only the diaper wearer's urine but also feces with a low water content with high reliability by positioning the sensing wire on the inner side of the diaper, and can reduce the discomfort of wearing a toilet detection device electrically connected to the detection wire. An object of the present invention is to provide a diaper having a urine detection function, and a toilet detection device that can be used in connection therewith.

Although the diaper 10 shown in FIG. 1 is a pad type diaper, the diaper according to an embodiment of the present invention may be implemented with various types of diapers such as a band type diaper or a panty type diaper in addition to the pad type diaper. In addition, the shape of the diaper 10 is not limited to the illustrated shape as long as the diaper 10 is worn on the wearable object to collect the feces. For reference, the target for wearing the diaper may be an animal, as well as an adult such as an elderly person or a patient, or a person such as an infant, an infant, or a child.

Referring to FIG. 1 , the diaper 10 may have a structure in which a lining layer 10', an absorbent layer 10'', and an outer cover 10''' are sequentially stacked. The lining layer 10' is positioned inside the absorbent layer 10'', and the absorbent layer 10'' is positioned inside the outer cover 10'''.

The lining layer 10' is a layer through which defecation is transmitted, and may be divided into an inner surface in direct contact with the skin of the diaper wearing target and an outer surface in contact with the absorbent layer 10'' that can accommodate the toilet. In an embodiment, the lining layer 10 ′ may be implemented with a fabric including a cloth, a knitted fabric, a felt, or a non-woven material, but is not limited thereto and may be implemented with a variety of materials.

The absorbent layer 10'' is located on the outer surface of the lining layer 10' to absorb and accommodate the bowel movements transmitted through the lining layer 10'. The outer cover 10''' is located on the outer surface of the absorbent layer 10'', and prevents the feces absorbed in the absorbent layer 10'' from leaking out of the diaper 10.

Hereinafter, the diapers 10 according to embodiments of the present invention may have slightly different shapes and wearable objects, but the outer cover 10''', the absorbent layer 10'' and the lining layer 10 as described above. ') may include the same or similar structures.

One end of the conductive detection lines 112 and 114 may be electrically connected to a toilet detection device to be described later.

In addition, the other ends of the conductive sensing lines 112 and 114 may be located at the other end of the inner surface of the diaper 10 or adjacent to the other end. For example, the other end of the conductive sensing lines 112 and 114 may be located at or adjacent to the other end of the waistband of the diaper 10 . The other ends of the conductive detection lines 112 and 114 may be electrically connected to a toilet detection device to be described later.

2 to 7 , at the end position 10a of the diaper where the distal ends of the conductive sensing lines 112 and 114 are located, a part of the diaper is cut in a 'C' shape to form a cutout 12 . In addition, at the end position 10a of the diaper 10, a 'C' shape is cut by the cutout 12 to form a bent portion 14 . Distal ends of the conductive sensing lines 112 and 114 are positioned in the bent portion 14 . In an embodiment, the cutout 12 and the bent portion 14 may be formed in a position close to the user's lower abdomen when the user wears the diaper 10 .

The cutout 12 and the bent portion 14 may be formed in a portion of the diaper 10 without the absorbent layer 10 ″. The cutout 12 and the bent portion 14 may be formed on one side of the peripheral region of the absorbent layer 10 ″″.
