Description

  The present invention relates to a medical or nursing pad suitably used for urine, sweat, blood, other bodily fluids, sewage such as adhering water and chemicals, water absorption of filth, and liquid absorption treatment.

  For example, a water-absorbing sheet in which granules (powder) of a water-absorbing agent are sandwiched between non-woven fabrics such as Japanese paper is disclosed as a material suitably used for absorbing water such as dirty liquid (see, for example, Patent Document 1). However, in this case, if the coating is broken, the granules are scattered, which is inconvenient to handle, and if the sheet gets wet by absorbing water from the sewage, etc., the touch on the sheet is worsened, and the sheet is in contact with the sheet. Soil enters the textile products and soils it.

  Further, a medical deodorized waterproof sheet is disclosed in which a water-absorbent sheet is used and a waterproof sheet is laminated on one side (see, for example, Patent Document 2). In this case, the waterproof sheet is used to contact the waterproof sheet. Although it is possible to prevent the infiltration of sewage into textile products, the touch of the wet sheet is not improved.

Furthermore, there are pads on the market in which a large number of water-absorbing papers of about 12 are used in layers and one side of the laminate is covered with a non-woven fabric and the other side is covered with a waterproof sheet. Since the water-absorbing paper is not so high, the slimy feeling generated from the water-absorbing paper is small even if it absorbs water. Although the use of a waterproof sheet can prevent the infiltration of sewage into other textiles, when the absorbent paper absorbs the sewage to some extent and approaches the saturated state, the sewage absorbed by the absorbent paper In addition to exuding and worsening the touch depending on the weight added to it, the pad is thick and inconvenient because it uses a lot of absorbent paper. In this case, if you try to prevent body fluid from seeping out, the number of absorbent paper will increase and the pad thickness will increase.If you reduce the number of water absorbent paper and reduce the pad thickness, body fluid seepage will soon occur while the pad is in use. The relationship that occurs.

  Therefore, the present invention has a good touch, can sufficiently prevent the exudation of the filth, and can prevent the infiltration of the filth into other textile products, and is thin and easy to handle for medical or nursing care. An object is to provide a pad for use.

  As a result of earnest research to achieve the above-mentioned purpose, in addition to the water-absorbing paper, a water-absorbing sheet having a larger water absorption amount is used. While maintaining the skin feel), the sewage soaked in the water-absorbing paper was further absorbed by the water-absorbing sheet, and therefore, the inventors found out that the spilled liquid from the absorbent paper could be prevented and completed the present invention.

  That is, the first device of the present invention covers one side of a laminate formed by laminating 1 to 5 water absorbent papers on both sides of the water absorbent sheet with a water-permeable material, and the other side of the laminate is covered with the water permeable material. A medical or care pad characterized by being coated with a water-impermeable material, and the second device is a laminate in which the laminate is laminated with two or three water absorbent papers on both sides of the water absorbent sheet, respectively. A medical or nursing pad according to the first aspect, characterized in that

  In the present invention, the water-absorbing paper is not particularly limited as long as it is a water-absorbing paper used for medical use or nursing care, but water-absorbing paper having a water absorption amount of 5 to 15 times its own weight with respect to 0.9% physiological saline is used. Is preferred. Further, the water-absorbing sheet is not particularly limited as long as it is a water-absorbing sheet used for medical or nursing care, but the water absorption is 20 times or more of its own weight with respect to 0.9% physiological saline, preferably 30 to 100 times, More preferably, it is preferable to use a water absorbing sheet of about 40 to 60 times.

  The water-permeable material used in the present invention is not particularly limited as long as it has water permeability that allows water to pass through the material. For example, a water-permeable nonwoven fabric, a water-permeable woven fabric, or a mesh film is preferably used. In this case, it is preferable to use a water-permeable nonwoven fabric or a water-permeable woven fabric that has a certain degree of smoothness even when wet. It is good to try to balance. The non-permeable material is not particularly limited as long as it is non-permeable so that water can be prevented from passing through the material, but a hydrophobic plastic film is exemplified, and it is particularly preferable to use a polyethylene film or a polypropylene film.

  As described above, the medical or nursing pad according to the present invention uses a laminate in which water-absorbing paper is laminated on both sides of the water-absorbing sheet, but this “lamination” is simply a state in which both are superimposed. However, both of them may be fixed by a method such as sewing, sticking, or adhesion. The present invention is not based on the premise that only one water absorbent sheet is used, but water absorbent paper is placed on both sides of an object in which one or more absorbent sheets are stacked, as long as the object and effect of the present invention are not hindered. Laminated laminates may be used, or one side of a laminate obtained by stacking a plurality of such laminates may be coated with a water-permeable material and the other surface may be coated with a water-impermeable material. Further, in such a laminate, within the range that does not impede the purpose and effect of the present invention, in the absorbent paper or the absorbent sheet, between the absorbent paper, between the absorbent paper and the absorbent sheet, or between the laminate and the coating material thereof. A deodorant or a fragrance may be included between the absorbent papers, or between the absorbent paper or between the absorbent paper and the absorbent sheet, or a laminate and its covering material, as long as the object and effect of the present invention are not hindered. Of course, another material (nonwoven fabric, woven fabric, paper, film, sheet, etc.) may be interposed between the two.

  When using the pad according to the present invention, the water-permeable material side is used as a surface material to contact the human body, and the non-water-permeable material side is used as a back material. The material that is first absorbed by the absorbent paper through the material and passed through it is absorbed by the water-absorbing sheet having a large amount of water absorption. In this case, the water absorbent paper present on the surface material side of the absorbent sheet is about 1 to 5 sheets in the case of the first invention, and the sewage absorbed by the water absorbent paper is the surface even when there is a load from the human body. It does not ooze out on the material side and is absorbed on the water absorbent sheet side. Therefore, the human skin is always in contact with the water-absorbing paper in a substantially dry state through the surface material during use, without contacting the slime (smooth state) when the water-absorbing sheet absorbs water and swells. , Do not feel uncomfortable. In addition, the water-absorbing paper on the lower side of the water-absorbing sheet absorbs more sewage from the water-absorbing sheet, and when the swollen water-absorbing sheet is in direct contact with the water-impermeable film, etc. Prevents contact with the film).

  In particular, as in the second device, when the water-absorbing paper on both sides of the water-absorbing sheet is two or three sheets, the thickness of the pad is also more suitable for handling, and the dry state of the water-absorbing paper on the front side is good, There is little discomfort due to wetness during use, and it can be more suitably used as a medical or nursing pad. As for the surface material, in particular, when a hydrophobic mesh film is used, there is a feeling of smoothness on the user's skin, and an unemployed cloth (rayon 30) that is usually used as the surface material of the water absorbent sheet. Compared with a non-woven fabric made of polyethylene fiber containing about% by weight), the sewage can be smoothly moved to the absorbent paper through the holes.

  Although the form for implementing this invention is as follows, these are only examples of the form for implementing this invention, and this invention is not limited to these embodiment.

(Embodiment 1)
FIG. 1 is an example of a medical or nursing pad according to the present invention, and a side surface of a laminate in which three sheets of water absorbent paper 2 (570 mm × 850 mm) are laminated on both sides of a water absorbent sheet 1 (570 mm × 850 mm). And the back surface is covered with the hydrophobic film 4, the surface side of the laminate is covered with the mesh film 3, and the film on the front side and the back side is fused around the laminate.

In this case, the water-absorbing sheet 1 has a water absorption amount 50 times its own weight with respect to 0.9% physiological saline, and has a weight per unit area of 30 g / m ² (polymer sheet 0040 manufactured by Best Products Co., Ltd.). The water absorbent paper 2 has a water absorption amount 8 times its own weight with respect to the physiological saline, and has a weight per unit area of 27 g / m ² . Was made. The water absorption amount of the laminate (100 g) with respect to 0.9% physiological saline was measured as follows, and it was 1000 g, and the water absorption amount was 10 times its own weight. Further, as the hydrophobic film 4 on the back side, a polyethylene film (manufactured by Fukusuke Kogyo Co., Ltd.) is used, and as the mesh film 3 on the front side, a polyethylene mesh film (manufactured by JEJE Sister Co., Ltd. (China)) is used. It was.

  Method for measuring water absorption amount: The laminate is dipped in 0.9% physiological saline for 10 minutes and then taken out. One end of the laminate is held by a support bar and is left hanging for 10 minutes. The water retention amount at this time is the water absorption amount. That is, the amount of water absorption = “the weight of the laminate after immersion and standing for 10 minutes−the weight of the laminate before immersion”.

  For example, when the pad according to the first embodiment is used as a rug for childbirth or a rug for an operation site, the sewage liquid that enters from the mesh film is absorbed by the water-absorbing paper through the holes of the mesh film, and further absorbs the sheet. Since the body fluid permeates to the side, even if there is a load due to weight, the user can use it comfortably with the feeling of touching the almost dry pad during use without spilling sewage from the absorbent paper. In this case, since a hydrophobic polyethylene mesh film is used on the surface side, a smooth feel is added, and the usability is improved.

(Embodiment 2)
FIG. 2 is another example of a medical or nursing pad according to the present invention, in which two sheets of water-absorbing paper 12 (570 mm × 850 mm) are laminated on both sides of a water-absorbing sheet 11 (570 mm × 850 mm). The side surface and the back surface of the laminate are covered with a hydrophobic film 14, the front surface side of the laminate is covered with the nonwoven fabric 13, and the nonwoven fabric on the front surface side and the film on the back surface side are bonded around the laminate.

In this case, the water-absorbing sheet 11 has a water-absorbing amount 60 times its own weight with respect to 0.9% physiological saline and has a basis weight of 45 g / m ² (polymer sheet 0045 manufactured by Best Products Co., Ltd.). As the water absorbent paper 12, using the water absorbent paper (crepe paper manufactured by Kami Shoji Co., Ltd.) having a water absorption of 8 times its own weight with respect to the physiological saline and having a basis weight of 27 g / m ² , Was made. When the water absorption of the laminate (130 g) with respect to 0.9% physiological saline was measured as described above, it was 1300 g, and the water absorption was 10 times its own weight. Moreover, as the hydrophobic film 14 on the back side, a polyethylene film (manufactured by Fukusuke Kogyo Co., Ltd.) is used, and as the nonwoven fabric 13 on the front side, a basis weight of 17 g of 30% by weight of rayon fibers and 70% by weight of polyethylene fibers is used. A non-woven fabric of / m ² (made by Shinwa Co., Ltd.) was used.

  When the pad of the second embodiment is used, for example, as a rug for childbirth or as a rug for an operation site, the sewage from the unemployed cloth 13 is absorbed by the water absorbent paper 12 through the non-woven cloth and further on the absorbent sheet side. Since the filthy fluid permeates into the body 11, even if there is a load due to the body weight, the body fluid does not ooze out from the water-absorbing paper, and the user can comfortably use the feeling of touching the almost dry pad during use. In this case, since the creped water absorbent paper is used, the soft feeling of the pad is improved.

  The present invention relates to a pad for medical use or nursing care, and particularly urine, sweat, blood, other body fluids, and adhering water generated at a site that requires a sanitary and reliable treatment, such as a surgical site or a birth site. It is preferably used as a medical or nursing care pad that is preferably used for water absorption and liquid absorption treatment of sewage and filth such as chemicals.

Is an example of a medical or nursing pad according to the present invention, which is a cross-sectional view of a pad using a laminate in which a water-absorbing sheet is interposed in the middle and three sheets of water-absorbing paper are laminated on each side. FIG. Is another example of a medical or nursing pad according to the present invention, wherein a pad is formed using a laminate in which a water absorbent sheet is interposed in the middle and two sheets of water absorbent paper are laminated on each side.
