Description

  The present invention relates to a nursing sheet that is a nursing bedding, and more particularly to a nursing sheet having a deodorizing function.

  Beds for the elderly and the sick who need care are required to be particularly clean, but are often contaminated by incontinence and discharges such as body fluids from wounds. For this reason, disposable nursing sheets and nursing sheets having functions such as antibacterial or deodorizing have been proposed (for example, Patent Documents 1 and 2). Moreover, what has the deodorizing ability is proposed so that the smell of these excrement may not permeate into the bedding.

  The care sheet disclosed in Patent Document 1 is a far-infrared ray such as zeolite between two antibacterial / deodorant cloths made of fibers carrying a substance having antibacterial and deodorant action such as silver. It consists of a radioactive material. This care sheet provides antibacterial and deodorant action to the cloth that comes into contact with the body of the care recipient, thereby suppressing the generation of bad odors and bacterial growth caused by the urine of the care recipient attached to the care sheet. Moreover, drying of the care sheet can be promoted by a filling such as zeolite sandwiched between two antibacterial / deodorant cloths.

Moreover, the sheet for nursing care disclosed in Patent Document 2 is a composite sheet in which an antibacterial thermoplastic fiber and a waterproof layer are laminated, and the thermoplastic fiber is water-absorbed. Since this thermoplastic fiber absorbs excreta such as body fluids, it prevents steaming due to long-term use of sheets and futons. In addition, since the thermoplastic fiber also has antibacterial properties, it is possible to prevent the growth of bacteria generated on the mattress or futon. In addition, bacterial growth due to excreta can be prevented.

  However, the care sheet described in Patent Document 1 has a high manufacturing cost because a filler such as zeolite is sandwiched between two cloths having antibacterial and deodorant effects. Moreover, although the said care sheet is washed and used repeatedly, it is preferable that it can be disposable from a hygiene side. Furthermore, although the bed sheet for nursing care described in Patent Document 2 has antibacterial properties, it deodorizes odors that are unpleasant for the subject and caregivers, such as the smell of the excrement of the subject and the aging odor. I can't. Therefore, an object of the present invention is to provide a care sheet having a deodorizing effect that can be manufactured at low cost and can be disposable, and a method for manufacturing the same.

  The present invention is a care sheet in which a top sheet, an absorber, and a back sheet that does not transmit moisture are laminated, and is characterized in that a tea leaf paste is carried on the top sheet. More specifically, the present invention provides the following.

  (1) A care sheet in which a liquid-permeable top sheet, a liquid-absorbent absorber, and a liquid-impermeable back sheet are laminated, the top sheet crushing tea leaves containing moisture A care sheet that is obtained by impregnating and drying the tea leaf paste obtained.

  (2) The care sheet according to (1), wherein at least one of the absorber and the back sheet is obtained by impregnating and drying the tea leaf paste.

  (3) The said surface sheet is a care sheet as described in (1) or (2) which is a nonwoven fabric.

  The top sheet is made of a sheet material having liquid permeability that allows liquid such as urine and sweat to pass through. Specific examples of the liquid-permeable sheet material include a woven fabric or a non-woven fabric made of synthetic fiber or natural fiber, or a perforated film formed by opening a synthetic resin into a sheet. Non-woven fabrics such as spunlace nonwoven fabrics and resin-bonded nonwoven fabrics composed of natural fibers (including semi-synthetic fibers) such as natural cotton and rayon, and synthetic fibers such as polypropylene are soft and liquid-permeable. It can be particularly suitably used as a material.

  The back sheet is preferably composed of a waterproof sheet material that does not allow liquid to permeate and has liquid impermeability. By constituting the back sheet with a waterproof sheet material, it is possible to prevent excrement such as urine absorbed and held inside the care sheet from the surface sheet surface from leaking out from the care sheet and soiling the bed or the like.

  Specific examples of the waterproof sheet material include a film obtained by sheeting a resin such as polyethylene, polypropylene, polyethylene terephthalate, and nylon. The second sheet may be configured by coating one side surface of a liquid-permeable sheet material such as a nonwoven fabric with a resin such as polyethylene.

  The tea leaf paste refers to a paste obtained by crushing a tea leaf containing moisture, and includes a deodorizing and antibacterial component derived from tea leaf such as catechin. The tea leaf paste preferably has a solid concentration of 5 to 12% by weight, particularly 7 to 10% by weight.

  The tea leaves used in the tea leaf paste are not particularly limited, and not only non-fermented tea leaves such as green tea but also fermented tea leaves such as black tea can be used. The tea leaves are preferably preliminarily soaked in water and softened, and then crushed, and tea leaves, which are residues obtained by extracting tea beverages, can be suitably used. The tea bowl may be crushed as it is extracted from a tea beverage or the like, or may be crushed after adding a liquid to make the water content about 88 to 95% by weight. As the liquid added to the tea bowl, a liquid having a pH of 5.5 or less may be used, for example, an acidic liquid such as carbonated water having a pH of about 3 to 4.5 may be used.

  As a method of supporting the tea leaf paste on the top sheet, a method of applying the tea leaf paste to the top sheet and drying at a predetermined temperature can be mentioned. Specific examples of the method for applying the tea leaf paste include a method in which the tea leaf paste is applied to the surface sheet by spraying or brushing, a method in which the tea leaf paste is immersed in a container containing the tea leaf paste, a printing method, and the like. After impregnating the tea leaf paste, the top sheet may be naturally dried or may be dried using a dryer or the like.

  As the absorber, pulp, highly water-absorbing resin, fiber and the like can be used. The shape of the absorber is not particularly limited, and may be laid between the top sheet and the back sheet in a sheet form, cotton form, powder, or granular form. A sheet-like or cotton-like absorbent body is preferable because it can prevent uneven distribution of the absorbent body. Specific examples of the absorbent include natural cotton or synthetic fiber cotton, a sheet or powder of a highly water-absorbent resin, water-absorbing paper made of pulp, pulverized pulp, and non-woven fabric, and composites thereof. . Cotton having a thickness of about 1 to 5 mm is particularly preferable because it can provide cushioning to the care sheet.

  The absorber is laid as uniformly as possible between the top sheet and the back sheet, that is, flat. Thus, by sandwiching the absorbent body between the top sheet and the back sheet, it is possible to prevent the excrement absorbed by the absorbent body, and the top sheet positioned on the absorbent body can suppress the smell of the excrement.

  ADVANTAGE OF THE INVENTION According to this invention, the sheet | seat for nursing care provided with the deodorizing function which can be disposable simply and at low cost can be obtained by carrying the tea leaf paste on the top sheet. Moreover, since the surface sheet has a deodorizing function, not only the smell of excrement absorbed by the absorbent body but also the body odor of the subject can be deodorized. Moreover, since the catechin in the tea leaf paste has not only a deodorizing function but also an antibacterial function, even a bedridden subject can spend clean and comfortable for a long time.
