DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an incontinence diaper, comprising a barrier layer of such as polyethylene film with a nonwoven layer fixed to it, and including two portions surrounding the lower part of the body and a crotch portion, connecting these two portions, intended for placing between the legs of a patient or wearer, there extended an area with fluff surrounded by soft tissue in the longitudinal direction of the diaper, over a large part of the portions surrounding the body and nearly the entire width of the crotch portion between the barrier layer and the nonwoven layer, as well at least one elastic band along both opposing sides of the crotch portion outside the fluff for pulling together the crotch portion about the thighs of the wearer when the diaper is in use.
One of the great problems, inter alia, in the care of incontinent patients in medical care is the frequency of leakage in the use of diapers. It has been found that the capillary forces in the absorption body in the diaper cannot counteract gravitation forces to any great extent, and thus there are often leakages, particularly when the patient is lying on his side. The incontinence diapers provided with elastic bands which are on the market today have an extension of the band solely in the crotch portion, and thus optimum flexibility in the whole diaper is not achieved, which means that the diapers must be manufactured in several different sizes, and in spite of this they often leak when in use.
The object of the present invention is to provide an incontinence diaper of the type mentioned in the introduction, in which the drawbacks attached to known diapers have been eliminated. Essentially distinguishing for the invention is that the elastic band continues from the crotch area in over both body-surrounding portions and along the entire length of the diaper with the band being attached with varying tension to the diaper material, this tension being greatest at the central portion of the crotch area, from which the tension decreases somewhat towards the distant portions of this area right up to both body-surrounding portions after which the tension tapers off to about half the original tension at the central portion of the crutch area, for optionally increasing again at the area just before the end edges of the body-surrounding portions to a value close to that at the central portion of the crotch area, for subsequently returning to approximately half of the original tension at the end edges.
With the aid of the invention there is now provided an incontinence diaper with an elastic band which achieves complete moisture-proofing between the body of a patient or wearer and the barrier layer of the diaper, both at the crotch portion of the wearer and around the waist and hips of this person. By the bands being attached with varying tension along substantially the entire diaper and the position of the bands being varied laterally at the waist fastening of the diaper it will be adjustable to patients having different waist measurements and body shapes. Since the bands also have a certain amount of stretch above the crotch area, a comfortable diaper is afforded and there is no risk that the barrier layer of the diaper, which is usually polyethylene film, being stretched out and thereby leaving gaps with leakage as a result. The more the attachment of the band varies transversely in the waist portion, the more will be the above-mentioned effect. Furthermore, the diaper in accordance with the present invention may be used with the same diaper dimension by persons of different sex, different waist measurement and different pelvic length due to the varying band tension.
The invention will now be described in detail below with reference to the accompanying drawings, on which
