 With the aging of society, the number of bedridden elderly people and elderly people who need nursing care is increasing, and there is an urgent need to provide equipment and nursing care products that match the situation. In addition, care for the elderly has to work in a bad environment with heavy labor, and the shortage of caregivers is deepening.

Disposable diapers are used at home, hospitals, nursing homes, etc., and are often used for elderly people who cannot urinate or defecate, and there are pants type, flat type, auxiliary pad, etc. by type. Depending on the situation, various items may be used in combination.

In addition, the current state of use of pet sheets is 1 to 4 sheets per day, and the method for excretion of pets is generally such that an absorbent sheet is placed on a dedicated container. It is laid and excreted on it (training and training).

Although newspapers and the like were widely used 10 years ago, since they have a low absorption capacity, they are now used for absorbent products such as laminated tissue, cotton-like pulp blended with water-absorbent polymer, etc. The one with high performance came to be used. There is also a blend of these with activated carbon, zeolite, ceramics, etc. to enhance the deodorizing effect.

[0006]

[Problems to be solved by the device]

 In the conventional disposable diapers as described above, the convenience of the caregiver side is pursued by pursuing the economical aspect, the ease of care, and the point of not absorbing and leaking, which is the most important function as a diaper. This is a pursuit, and it cannot be said that nursing care for the elderly is sufficient. A diaper is often worn for several hours, and when used for elderly people with weak skin, the water from urination may cause the buttocks to become moistened, causing bacteria to multiply in the excrement, causing damage to the skin and causing rashes. is there. There is also a problem that the deterioration of the environment due to the generation of odors such as this discharge adversely affects the mental health of the elderly and caregivers. Further, the above-mentioned conventional pet sheets are not sufficient in terms of deodorizing effect.

The object of the present invention is to reduce the bad odor and impart the fragrance to the environment for the mental health of the aged and caregivers, and to prevent the skin rash. It is also to provide an absorbent sheet having an improved deodorizing effect.

[0008]

【Example】

 FIG. 1 is a sectional view of an absorbent sheet 1 according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a part of the absorbent sheet 1 in a cutaway manner. The absorbent sheet 1 used as a diaper includes a topsheet 4 made of a water-permeable nonwoven fabric, a backsheet 5 made of water-impermeable polyethylene, and an absorbent sheet interposed between the topsheet 4 and the backsheet 5. It has a body 2 and an encapsulating sheet 3 made of the same material as the topsheet 4 and encapsulating the absorbent body 2. The encapsulating sheet 3 is adhered into a tubular shape with both ends in the width direction in the unfolded state being laid one on top of the other, and the absorber 2 is inserted therein. Both ends of the back sheet 5 facing outward in the width direction are bonded to both ends of the top sheet 4 in the width direction by using, for example, a hot-melt adhesive or the like, and the encapsulating sheet 3 encapsulates the encapsulating sheet 3 therebetween. The absorbed absorber 2 is interposed. In this state, the both ends 9a and 9b in the longitudinal direction are joined with a heat seal or a hot melt adhesive, whereby the absorber 2 is sealed.

The absorbent body 2 has a cotton-like pulp 6, a water-absorbing polymer 7, and a crushed product 8 of wood which is a health-effective component. The wood pulverized product 8 has antibacterial properties, bactericidal properties, deodorizing effects, and contains a tree scent component suitable for mental health. Further, the wood pulverized product 8 also has a water absorption capacity, Absorbs 4 g of water.

[0012] The tree used for the crushed wood 8 contains components such as hinokitiol (3- and 5-isopropyltropolone) having antibacterial properties, and the Aomori Hiba tree is preferable. In addition to this, it has an antibacterial effect similar to that of Aomori Hiba, and its cleansing ingredients and scents have a cleansing effect on the skin, and are highly effective in terms of mental health. It may be blended or used alone, and it is also possible to blend it with herbs such as spinach, honeywort, bracken, sampou, and pearl millet, which have a cleansing effect on the skin. Well, this can further enhance the effect. The above herbs are effective for boils, swellings, detoxification of swellings, chronic skin diseases, eczema, and skin troubles. Generally, wood contains about 0.5 to 2% of an effective sap component depending on the age, geology, sunshine, temperature, etc. These sap components make it difficult for the effluent to be decomposed by bacteria, reduce the generation of components harmful to the skin, and keep the weakened skin clean and healthy. Although the active ingredients of trees have recently been shown to be useful in forest bathing, etc., the natural scent of trees wraps up the environment, which can promote mental enjoyment and health through the sense of smell.

About 1 to 100 g is suitable for the amount of the crushed wood 8 to be mixed in one diaper, and in terms of material ratio, cotton pulp 6: water-absorbing polymer 7: crushed wood 8 = 10: 2: 2-4 is preferable. The granular material 8 of the crushed wood 8 is preferably about 30 to 200 mesh, and the granular shape is cut into a polygon having a large surface area. For example, in the case of an adult diaper, the usage time is about 2 to 10 hours. It is preferable that the scent diffuses efficiently according to this time. In addition, as the material used from the viewpoint of the global environment, it is also possible to effectively use the scraps and sawdust after the sawing.

As another embodiment of the present invention, instead of the crushed wood material 8, fine particles obtained by concentrating sap containing components such as phytoncide, which are generally known, are mixed in the absorbent body 2. To do. The fine particles generate a scent of trees even in a dry state, and when dissolved by water such as urine, they neutralize main components of odor such as ammonia and evaporate scent components of trees. It is promoted to increase the fragrance. That is, when the absorbent body 2 absorbs water, the effect of absorbing the main component of odor such as ammonia is enhanced, and at the same time, the aroma of the tree is also strengthened.

As still another embodiment of the present invention, as shown in FIG. 3, the absorbent sheet 1 of FIGS. 1 and 2 is placed inside a container 12 made of vinyl chloride and having a substantially U-shaped cross section. It is laid and used as a pet toilet 11 for dogs and cats.

As a result, the antibacterial effect of the sap suppresses the bad odor caused by the decomposition of urea and protein, which are the origin of the odor, into various bacteria, and the scent component wraps around the odor of excrement and suppresses the bad odor. .

By incorporating the natural scent of dogs and cats placed in an artificial environment, the rhythm of living in nature can be restored, and an optimal environment for relieving stress through the sense of smell and maintaining health Can be created.

The absorbent sheet 1 with a scent of wood has less pulp odor that dogs and cats hate compared to the prior art pulp-based absorbent sheet, and is close to the conditions of places where dogs and cats excrete in nature. Can be excreted. As one experiment, when the directivity of the conventional absorbent sheet and the absorbent sheet 1 of the present invention was tested, it was confirmed that they excreted in the absorbent sheet 1 of the present invention. Further, comparing the number of times of excretion to the same absorbent sheet, it was confirmed that the absorbent sheet 1 of the present invention has a higher frequency of excretion and prefers excretion without discomfort. Dogs and cats originally lived in forests and grasslands and tend to familiarize themselves with the scent of nature. Because of this, training for excretion in a special toilet container can be easily performed. As a result, it may take a lot of time and effort for the discipline of an expert to perform discipline for excretion, and in the case of individual discipline, this problem can be solved. can do.

Furthermore, when the pet toilet 11 is used, the feet of the pet can be kept clean due to the antibacterial and bactericidal effects.

Furthermore, the scent of wood such as cypress is also effective for stabilizing the mental state of humans, and this has been confirmed from the medical aspect such as the effect of forest bathing. Therefore, it is effective for breeders as well as eliminating the smell of pets. Furthermore, the urine of humans and dogs is normally odorless at the time of voiding. The causes when there is odor are as follows.

That is, the ammonia odor is a general abnormality of urine, and ammonia has a specific odor, but at room temperature, fresh normal urine contains a small amount of ammonia, so the ammonia odor is Absent. However, it may contain high amounts of urea and, in addition, high amounts of NH ₄ +. The cause of ammonia odor may be urea, which is decomposed into ammonia by urease-producing bacteria, or NH ₄ + which is converted to NH ₃ by heat from the outside. Can be a pathogen or a contaminant. Moreover, fresh excretion urine accompanied by ammonia odor suggests urinary tract infection by urease-producing bacteria.

Further, when a large amount of protein is decomposed by bacteria, it gives off a rotting odor, and in the case of ketone urine, it gives a specific odor to urine.

As a result of an experiment conducted by the inventor of the present invention with respect to Escherichia coli and urease-producing bacteria using the pulverized product 8 of wood, it was confirmed that it has an antibacterial effect.

[0024]
