Description

DIAPER FOR ADULT

The present invention relates to an adult diaper, and more particularly, prevents the absorbent pad from clumping together when absorbing urine, secretions or defecation of the elderly and impairing the user's wearing comfort, and the absorbed urine, secretions, or toilets do not come into contact with the skin. It is directed to an adult diaper that absorbs quickly and dries the surface so that it is comfortable and can be worn hygienically by doubling antibacterial as well as deodorizing and deodorizing functions.

In general, diapers are used to receive urine and feces of people who cannot cover urine and feces (eg, infants and dementia patients) or people with reduced mobility (eg, patients and the elderly). A person who wears a diaper cannot change the diaper by himself or herself after having a bowel movement, and usually a guardian (eg, a parent, a family member, a nurse, a daycare worker, etc.) changes the diaper.

And the adult diaper is worn by the elderly or incontinence patients, and serves to absorb urine, secretions, or feces. A commonly known adult diaper is a pad that covers the genitals and anus, and the front and rear protrude to the front and rear of the waist. and waist fixing means provided on both front and rear sides of the pad to wear the pad on the waist.

And the pad, the wearer's genitals and anus in close contact with the upper sheet to permeate urine, secretions or feces; It is provided in a waterproof sheet to prevent clothes from getting dirty.

In addition, the upper sheet is composed of one of synthetic resin, synthetic fiber, and natural fiber so that urine or secretions can permeate.

In addition, the waist fixing means is provided on both sides of the attachment elastic band provided on the front or rear both sides of the pad and the attachment elastic band provided on opposite sides provided with the attachment elastic band is to be composed of an attachment portion to which the attachment elastic band is attached. And, the attachment elastic band and attachment part are the most widely used ones made of Velcro tape.

The adult diaper configured as described above is used for absorbing urine, secretions, or feces of the elderly. It can lower the will to live and further cause depression or social avoidance. Bacteria and odors caused by persistent moisture limit social activities or cause infection with other diseases.

In addition, adult diapers currently sold in Korea use disposable diapers (or panties) as they are or wear pads with increased absorption, so that when a user uses disposable diapers (or panties) or pads for a long time, the genital area There is a problem that can cause other skin diseases, etc. because it becomes wrinkled and weak due to moisture.
