[0002] [Prior Art] Conventional diapers have insufficient diaper dimensions, and diapers that are too large in area have urine spread over a large area and come into contact with the skin, or leakage from the side of the diaper. Depending on the situation, there are problems such as getting wet sleeping clothes and sheets, and that it is difficult for the caregiver to properly wear the diaper on the patient. There is also a problem in the method of using the water absorbing polymer and the water absorbing fiber. [Problems to be solved by the invention] Water-absorbing fibers used for diapers, efficient distribution of water-absorbing polymers, rational size of diapers, prevention of side leakage of urine from diapers, and caregiver (EN) Provided is a method for easily and correctly setting a diaper. [0004] [Means for Solving the Problem] FIG. 1 shows a state in which the diaper 1 has absorbed urine when the patient is supine, and arrow D
Indicates the head direction. In the case of a female, the urine absorbing part 2 is long on the head side D behind the waist with respect to the position 3 corresponding to the clitoris, and is distributed substantially evenly on the left and right with respect to the center line C. [0005] FIG. 2 shows the distribution of urine when a female patient is lying down with the left side down. The urine absorbing part 2 has a head at the back of the waist with the clitoris-equivalent position 3 as the apex. It is long on the arrow D side, is biased to the left side of the body with respect to the center line C, and is distributed more on the arrow H side. [0006] In the case of a conventional diaper, although there is a residual water absorption capacity as a whole, leakage is likely to occur in the case of recumbency, and even if the distribution of the water-absorbing polymer is determined in the laboratory, it is practical for the patient to change the body position. Results were not obtained. The diaper is supine,
It must have a structure that efficiently absorbs urine in both cases of recumbency. [0007] A model for examining the distribution of the urine absorption amount with respect to the center line C is shown in FIGS. 3A and 3B. When viewed from the left-right direction of the diaper, that is, the AA ′ direction in FIG. 1, the six absorption units V made of the water-absorbing polymer, the water-absorbing fibers, etc. are evenly distributed to the center and the left and right around the center line C. Comparing the case of FIG. 3A with the case where the same amount of absorption units as in FIG. 3A is used as shown in FIG. 3B, four absorption units V are arranged on the center line C, and one absorption unit V is arranged on each of the left and right sides. to see. In the case of supine, the absorption unit V of FIG. 3A and FIG. 3B having substantially the same amount works centering on the center line C, but in the case of recumbency, since the absorption action is biased to one side, the absorption unit V is located inside the absorption action range 5. The number of absorbing units V to enter is four in the case of FIG. 3A and five in the case of FIG. 3B. [0008] That is, when the same amount of absorbent material is used, it is more effective for lateral leakage of urine to distribute more in the vicinity of the center line. [0009] Next, the examination of the size of the diaper is shown in FIG.
This is shown in FIGS. FIG. 4 is a cross-sectional view of the lower back of the human body seen from the direction of the foot. The pelvic prominences 7, 7 project at a distance H of about 100 to 120 mm around the spine protrusion 6, and the supine position is long. It is a place where bed sores occur in Ushikatsu. [0010] Therefore, when using the same amount of urine absorbing fiber,
It suffices to support the protrusions as thick as possible and give sufficient urine absorption capacity. Also, the wetted part of the diaper that contacts the body should have as small an area as possible. Furthermore, the width of the crotch area of the diaper is narrow, and this area absorbs most of the urine, and as a result of the experiment, the width H between the projections is set to 200 mm, which is larger than the width H between the projections in consideration of the slight shift to the left and right. , It was used for patients. In FIG. 5, the spread width L1 of the urine absorbing part 2 of the diaper 1 in the case of lying on the back was measured. In FIG. 6, the spread width L2 of the urine absorbing part 2 when lying down was measured. [0011] FIG. 7 shows a conventional diaper shown in FIG. 11 having a width of 300 and a length of 650 and approximately 10 grams of a water-absorbing polymer distributed almost evenly on the entire cotton-like pulp. Was measured, and since the patient repeatedly recumbent and supine, the spread width L was shown in relation to the absorbed urine volume without distinguishing L1 and L2. The total weight of one diaper in the experimental example is about 110 grams. FIG. 11 shows a conventional diaper in which a cotton-like pulp 21 and 22 containing a water-absorbing polymer on the inner surface is sandwiched between a water-impermeable back sheet 10 and a water-permeable top sheet 12 to seal the peripheral edge F. [0012] FIG. 8 uses the same amount of water-absorbing polymer and water-absorbing fiber as in FIG. 7, and has a total weight of 110 grams and a width of 200.
The urine volume and the urine absorption part spread width L are shown for a diaper of mm × length 580 mm. FIG. 9 shows a case where 10 g of a water-absorbing polymer is additionally sprayed over the central portion of the diaper of FIG. 8 over a width of 100 mm and a length of 300 mm, and A, B, and C in each figure are almost average values (each). (By the method of least squares). [0013] FIG. 10 shows the graphs A, B, and C of the average values on the same drawing. Looking at them, A and B are almost unchanged, but C has the same urine absorption amount. In contrast, the width L
Indicates that it is 20 to 25% smaller, that is, it has a large absorption capacity. If there is no omission in the "dots" in the figure,
The "X" indicates the case where the diaper leaked. [0014] In addition, the urine volume in the drawing is about 1 for an old woman throughout the day and night.
It shows the amount of urine output every 2 hours, and based on the fact that it has a urine absorbing capacity of 500 grams, it is enough to change the diaper twice in the morning and evening for the old woman in the example of FIG. I was able to reduce the time and effort of care. [0015] Although the leakage of urine from the diaper eventually comes to the limit of the urine absorption capacity, in the case of recumbency, it often leaks to the side and may leak within the planned urine absorption capacity. Many. Of course, the distribution method of the urine absorbent is of course relevant. [0016] As for the size of the diaper, thicker and narrower than thin and wide uses the same amount of material to provide less body wetting area and better cushioning. As for the width, the absorption capacity is 300 as shown by A and B in FIG.
Width of 200 mm
Leakage does not occur even if the amount of urine is 500 grams when the absorption capacity of the central portion is increased in millimeters. [0017] As for the length, it is understood from FIG. 9 that the spread width is slightly less than 500 mm with respect to the urine volume of 500 g, and therefore 600 ± 50 mm is sufficient when looking at the clearance. [0018] Leakage of urine is likely to occur when urine exceeds the absorption capacity of the diaper and when the diaper shifts laterally from the centerline of the body. Generally, care for patients such as the elderly is
It is often done from the side, and diapers are often changed from the side. In this case, if the center line of the diaper is displayed in the longitudinal direction of the diaper on the water absorption side of the diaper, that is, on the surface, it becomes easy to follow the spine or the line between the groins. [0019] As shown in FIG. 1 and FIG. 2, in the case of a female, the clitoris position 3 is close to one end of the urine absorbing part 2 and greatly spreads toward the other end. Therefore, as shown in FIG. If the anal position 16 is displayed, the diaper can be effectively used. Similarly, for men, it is sufficient to display the anal position as one reference, and generally, men mainly absorb an amount of urine on the side of the penis, centering on the anus. [0020] The discharged urine runs through the gaps of the water-absorbing polymer by capillary action in the portion where the water-absorbing polymer is densely dispersed, but when the water-absorbing polymer starts to swell, it becomes difficult to pass through the urine, and between the water-absorbing fibers. The speed of urine running by capillary action is
Faster than running between water-absorbing polymer layers. Therefore, it is desirable that the excreted urine is rapidly diffused and retained in the water absorbing fiber, is in contact with the water absorbing polymer, or is absorbed by the water absorbing polymer coarsely dispersed in the water absorbing fiber. As shown in FIG. 13, the water absorbing ability of the water absorbing polymer gradually rises in a few seconds to several tens of seconds. Therefore, the diffusion of urine in the diaper is kept by the water absorbing fibers, and the water is gradually retained. It is better to move in. [0021] An experiment in which the water-absorbing polymer absorbs urine and swells to make it difficult for urine to pass between the water-absorbing polymers is performed in the same manner as in the experimental example of the structure shown in FIG.
In a diaper having a length of 00 mm and a length of about 600 mm, even if a total of 20 g of a water-absorbing polymer, that is, 10 g inside the cotton-like pulp and 10 g between the cotton-like pulps is used, there is no practical problem as shown in FIG. Did not occur. That is, in the case of FIG. 9, 10 g of the additional water-absorbent polymer was sprayed in an area of 100 mm × 300 mm between the two cotton-like pulps in the central portion of the diaper, but the cotton-like pulp surface was partially supported and partially Did not cause any trouble in the urine absorbing action even when the water-absorbing polymer adjoining each other existed, and did not cause problems such as polymer migration and uneven distribution due to handling. [0022] Due to the above, the outer size of the diaper is about 20.
When the cross section is 0 mm × 600 mm, the cross section becomes as shown in FIGS. 14 and 15. In FIG. 14, two layers of cotton-like pulp 22 and 21 are placed on the water-impermeable backsheet 10, and the lower surface of the cotton-like pulp 22 is evenly spread over substantially the entire surface thereof, and about 10 grams of the water-absorbing polymer 20 is dispersed. Then, 10 g of the additional polymer 26 is evenly spread over the area of 100 mm × 300 mm in the central part of the diaper between the two layers of cotton-like pulp, and covered with the cotton-like pulp 21 on the whole, and the whole is euphoric. The surface sheet is covered and the peripheral edge F is folded and brought into close contact. Cover the outer surface of the cotton-like pulp with tissue paper to prevent the cotton-like pulp from splashing during operation. The sprayed water-absorbent polymer is held by the irregularities of the cotton-like pulp and practically does not cause any trouble such as uneven movement. [0023] FIG. 15 illustrates two layers of cotton-like pulp 27 sandwiched between the euphoric backsheet 10 and the water-permeable backsheet 12.
A total of 10 grams of a water-absorbing polymer was mixed and contained in each of the 28 substantially evenly, and two layers of cotton-like pulp 27,
10 grams of additional polymer 26 was sprinkled between 28, as in FIG. The urine absorption state of the diaper shown in FIG. 15 is shown in the graph of FIG. Also in the case of FIG. 14, the urine absorption state was almost the same as that of the case of FIG. [Example] FIG. 16 shows a perspective view of a diaper in an example. The outer dimensions are width 200 ± 30 mm, length 600 ± 50 mm,
The water absorbing fibers are distributed almost uniformly over the entire surface, and the width is about 10 in the center.
The state in which the additional polymer 26 is sprinkled on the part of 0 mm × 300 mm to 400 mm in length is illustrated. The peripheral portions F, F,
F'and F'were folded and brought into close contact. The center line 14 and the anal position 16 or the clitoris position 15 on the center line are displayed by printing or other method in the longitudinal direction of the diaper. FIG. 17 shows a ladder-shaped embodiment. [Operation] According to the present invention, when a patient using a diaper uses the same water-absorbing material for both supine and recumbent, the water-absorbing material is extremely effectively used for absorbing urine. In addition, the amount of urine emitted by a patient is generally considered to be in the range of 20 to 50 grams per hour, but within the range of water absorption capacity set for this expected amount, the diaper made to a size of about 200 mm x 600 mm is It is possible to efficiently give a sufficient urine absorbing capacity regardless of the small area for wetting. Since the center line and the anal position or the clitoris position are displayed on the diaper, it is easy to set the diaper on the patient. [Effects of the Invention] [Effect of the invention] Since it has a simple structure, it is easy to manufacture, the manufacturing cost is low as a disposable diaper, and it can give a sufficient urine absorbing ability, and can be set correctly on the patient's body. It's easy.
