Description

[Detailed description of the invention] The present invention is based on the fact that #pickles can be heated by themselves.
x, Disposable shirts worn by the elderly, sick, etc.1
More specifically, the excretory fluid has a structure KII# mold which results in the prevention of a9hO from leg slI and/or shoe S).
I! Concerning throw away shims - Conventionally, several proposals have been made to improve throw away shims that do not require any special parts, and these have been put into practical use. There is. However, although this type of shimuri has been improved to the point where it is not much different from the type 40, which uses disposable shims made mainly of pulp and pants without covers, it does not affect the body. Accidentality,
Compatibility KTh g5-1 Even if it is not the same at the time of wearing, IIIyII person's body movement *II
Because the wearability and compatibility with Cyoasuite is poor,
One leg for Shimuri! There is a drawback that the soaking liquid leaks from the waist circumference. However, the drawback is that the disposable shim is rusty, and the absorbent material is relatively rigid.

Attach it to both Ila and W6 and use the fastening tape] Scissors form IIvl: Take measures to retain a),
You can say avoid JIIvh.

By the way, disposable simulator Ks? -, since the absorbent body interposed between the top sheet and the grasshopper sheet absorbs the excreted fluid, the absorbent body absorbs the excreted liquid.
[Be efficient (absorb), and make the absorbent material efficient (
In order to utilize it, it is preferable to diffuse the excretory fluid all around the periphery 1aK of the syringe.

However, the idea of placing a superabsorbent polymer in the central area of the a-container O using a disposable shim K was actually successful.
56-ago@49. According to the same m-1soy publication KTh-te Todoroll5n''C-, ζ0 publicly known device, due to the characteristics of superabsorbent polymer, the axillary bomber is placed in the central area of the aIIL body, where excretory fluid is discharged. Large amount absorption and retention stL
Become. At the scene, the body was sticky due to contamination from excrement.
It may cause discomfort to the wearer, or it may cause dermatitis such as turnips [caused by infertility]. Since the weight is added by 1, the central arm of the body is lowered, and the uneven distribution is shifted, so the excrement fluid that is discharged into the body of the animal and JC is 0.
In a workplace where the distribution of grades is uneven, it becomes difficult to make effective use of the WkIR body.

Therefore, the known idea O #c @ collection body 0 central part MKj
Although it may be understood at first glance that %/% is a good example of arranging high-absorbing goods such as I and astringent polymers, in R pair, excretory fluid k is chewed, O is surrounded by mK flesh, etc. If it is made to diffuse physically, there will be a drawback that the excreted I [is excreted from the surrounding ins].

Therefore, the present inventors have overcome the aforementioned drawbacks.

In addition, we are actively researching the effective use of superabsorbent polymers in disposable shims.
As a result, I arrived at this line [Heating with solution] by a relatively simple means.

In other words, the main method of Motoya@O is to use a single layer of highly absorbent polymer.
It is most preferable that the absorbent body is arranged in a band shape so as to face each other at least at opposite end portions of the absorbent body. Then place the absorber 0II on the 4 sides (k) until each end. In addition, when the liquid is diffused, the excreted liquid is prevented from leaking to the outside at the end 11eC, thereby providing an improvement in disposable shims.

According to the present invention, the main material of the present invention is 111 crushed I (1), which is the main raw material, and an absorbent press is applied between the soft wires of the pulp and 1#.
Excretion pickled liquid mineral dispersion t # 1g is raised by the kernel, & used - picked up and improved shimuri 1l-II & provided.

Another object of the present invention (a) will be understood from the following description.

A summary of the present invention for peracidifying m-blocking OII targets is as follows. 9 absorbent body) - one layer of super absorbent polymer is arranged on the absorbent body i

And both ends in the radial direction, II is in the form of a vaginal aqueous net, and the surface is covered with an absorbent sheet, and the whole surface is covered with an absorbent sheet. Re, Katsu, SoO Chuo Ikuryo! When the first part 31 is folded inwardly, the upper 1 m absorber nail has a narrower width than the folded width of the member 270 (and the unfolded IIOIIg), and the width of the member 2 The top surface and both ends 111 in the radial direction of the pulverized layer n are stacked on top of ``7'', and the upper surface and both ends 111 in the radial direction are rolled up over the entire area in a state where the upper surface and both ends 111 in the radial direction are engraved with a T-shaped or Chofu-shaped sheet. The sheet device, a3, has a hole elongated in the direction of the O fibers, and has a slit. y) Known as J, when the pulp is rolled up and soaked in the ζO absorber 10, the interfiber bonding force of the pulverized pulp is strengthened and the rL density is high. As well as improving the diffusivity of

According to the above-mentioned sheath h2s, 33), the amount of excreted liquid collected in the absorber 10 KM seeps out from both ends W in the width direction of the upper surface of the absorber is relatively small (and the amount of waste IL of the absorber is The effect of being prevented is obtained.

An absorbent body shown in Iual is interposed via a hot melt l, and an elastic member made of polyurethane foam with a width of 20 mm is attached to the 7 laps at both ends of the absorbent body, and the m part where the back sheet and the two top sheets meet is attached. A diaper was made by bonding with hot melt and having superabsorbent polymers arranged as shown in . The above-mentioned top sheet has an MO ratio of polyester and rayon of JtOg, and its weight is 4.

As a comparison product, the superabsorbent polymer layer was made of gold.
I made a sample of the dilute acid that was not allowed to be kept, and measured the urine o@n from the actual crystal of this invention, and it was 9.70! The results are as shown in the table below.Incidentally, the comparative product was proposed by the present applicant in patent application WiHs No. 5-.

According to this system, it is clear from the test results of the above-mentioned products related to the present invention that it is possible to considerably reduce the leakage of excretory fluid from the [circumference, chest circumference]. If such an excellent NJ body is obtained, the liquid will spread to the waist circumference (p1, legs, four), and the liquid will be absorbed into the body.
This is because the layer of highly absorbent polymer placed in the area functions as a liquid-proof zone. In the case of pressing or embossing on the body, the shimming is absorbed in the central area.
Because it promotes the diffusion of the dipping solution and prevents the leakage of water that spreads around it as mentioned above, it is recommended to apply a layer of highly absorbent polymer to the lower back and legs. Compared to conventional disposable scissors which do not have a press and are not embossed on the absorbent body, R211L has nine disadvantages of conventional scissor bites. t IJI can be further significantly resolved.
