Description

  The present invention relates to a low-cost absorbent auxiliary pad that can appropriately prevent leakage of loose stool and a method of using the same.

  In general, there are an adult paper diaper such as a tape stopper type and a pants type, and these paper diapers are appropriately selected and used according to the necessity of care in excretion of the user. These absorbent articles are composed of a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the two sheets. By adopting such a configuration, body fluid such as urine passes through the top sheet of the absorbent article and is absorbed by the absorbent body, and does not leak to the outside by the back sheet.

  By the way, tape-type and pants-type paper diapers (hereinafter referred to as tape-type diapers) may be used alone or in combination with a urine picking pad on the inside. In most cases, it is used in combination with a urine absorbing pad, and the urine absorbing pad is stacked on the top sheet. This is because the cost per sheet of diaper is high. After excrement is absorbed and held by a urine collection pad that is cheaper than tape-type or pants-type diapers, only the urine collection pad is replaced. This is because, even after excretion, it is not necessary to replace the costly tape-type or pants-type disposable diapers, and the absorbent article can be used economically at a low cost.

  Here, the urine removing pad has various sizes and shapes according to the urine volume, and can reliably absorb the excreted urine and prevent leakage. However, for soft stool, watery stool and diarrheal stool (hereinafter referred to as soft stool), the absorbability is insufficient, and the loose stool may leak to the outside of disposable diapers such as a urine collection pad and a taped type. Therefore, a urine collection pad intended to prevent leakage of loose stool has been studied.

  As a urine absorption pad for the purpose of preventing leakage of loose stool or the like, for example, in Patent Document 1, in a urine absorption pad including a top sheet, a back sheet, an absorber, and a three-dimensional gather, at least A cup portion that is recessed in a cup shape as viewed from the clothing side surface is provided in a portion extending laterally from the protruding portion of the three-dimensional gather within a range behind the front end of the crotch portion. A urine absorbing pad is disclosed.

(Evaluation of leakage prevention for loose stools)
The following evaluation was performed by 20 monitors. Each absorbent auxiliary pad is substantially U-shaped so as to surround the urination area and defecation area located at the crotch part of the tape-type disposable diaper from the front part to the rear part and along the inside of the three-dimensional gather of the absorbent article. For the leakage of soft stool and the like when worn, either “there is a leakage of soft stool” or “there is no leakage of soft stool” was selected, and the evaluation result was calculated according to the following criteria.
◎: When there is no leakage of soft stool 16 to 20 people ○: When there is no leakage of soft stool 11 to 15 people Δ: “No leakage of soft stool” 6 When the number of people is 10 or less: ×: When there is no leakage of soft stool, etc., 0 or more and 5 or less

(Comfort evaluation)
At the same time as evaluating the prevention of leakage of soft stools, etc., the comfort at the time of wearing was also evaluated. Either “I feel foreign matter” or “I don't feel foreign matter” was selected, and the evaluation results were calculated according to the following criteria.
◎: When “no foreign body sensation” is 16 or more and 20 or less ○: When “No foreign body sensation” is 11 or more and 15 or less △: “No foreign body sensation” is 6 or more and 10 or less When x: “No foreign body sensation” is 0 or more and 5 or less In addition, regarding the results of the evaluation of prevention of leakage of soft stool and the like and the evaluation of comfort, Δ or more was regarded as acceptable.

  From Examples 1 to 5, it can be seen that according to the present invention, an absorbent auxiliary pad capable of preventing leakage of loose stool or the like can be obtained. On the other hand, it can be seen that the absorbent auxiliary pad of Comparative Example 1 has a short length in the longitudinal direction of the absorbent auxiliary pad and therefore cannot sufficiently prevent leakage of loose stool or the like. Further, in the absorbent auxiliary pad of Comparative Example 2, the absorbent auxiliary pad extends to the outside of the three-dimensional gathers of the tape-type paper diaper because the outer periphery of the cross section in the short direction of the absorbent auxiliary pad is large and the cross-sectional area is large. It can be seen that leaks such as loose stools cannot be sufficiently prevented. Furthermore, in the absorptive auxiliary pad of the comparative example 3, since the outer periphery of the cross section of a transversal direction is small, it turns out that the fitting property of an absorptive auxiliary pad falls and it cannot fully prevent leaks, such as a loose stool.
