Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for wiping or disinfecting the oral cavity, anus, skin, affected parts, etc. by impregnating a liquid such as a chemical solution or a cosmetic solution (hereinafter referred to as a chemical solution etc.). The present invention relates to a cleaning tool such as a cotton ball and a cotton swab.

[0002]

2. Description of the Related Art A cotton swab 50 as shown in FIG. 12 is used to clean the mouth of a care recipient or to disinfect a patient's skin during surgery or injection. The cotton swab 50 is composed of a spherical body 52 in which loosely gathered cotton fibers 51 are grouped into a substantially spherical shape having a diameter of about 20 mm, and a shaft 53 having one end located substantially at the center of the spherical body 52. Then, a plurality of swabs 50 in which the spherical body 52 has been impregnated with the chemical solution 54 in advance are sealed in a liquid-tight packaging bag 55, and one of them is taken out and the oral cavity and skin are cleaned and disinfected. The swab 50 may be used by impregnating the spherical body 52 with the chemical solution 54 immediately before use. In addition to the cotton swab 50, a cotton ball consisting of only the spherical body 52 without the shaft 53 may be pinched with tweezers and used.

[0003]

However, in the conventional swab 50, while the spherical body 52 absorbs the chemical solution 54 more than necessary into the inside thereof, the swab 50 is actually used on the surface of the spherical body 52. There is a waste that the internal chemical solution 54 occupying most of the absorbed amount and being discarded while being absorbed by the spherical body 52 is wasteful and uneconomical.

[0004] Japanese Patent Application Laid-Open No. 9-47377 discloses a cotton swab in which a resin is adhered to the surface of a cotton ball portion so that the cosmetic liquid does not penetrate into the inside. According to this swab, the cosmetic liquid can certainly be wasted, but there is a problem that the cosmetic liquid only adheres to the irregularities of the resin film on the surface and the amount of the cosmetic liquid is too small to be wiped well.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to absorb a necessary amount of a chemical solution or the like necessary for wiping or disinfection, and to prevent the wasteful absorption of a further amount of the chemical solution, so that the chemical solution or the like can be effectively removed. An object of the present invention is to provide a wiper that can be saved.

[0006]

In order to achieve the above object, a wiper according to the present invention comprises a core material having a relatively low liquid absorbency and a skin having a relatively high liquid absorbability surrounding the core material. 4-60mm in diameter (more preferably 10-40mm)
With a spherical body. "Spherical body" is not limited to a true sphere,
Shapes close to spheres such as elliptical spheres and polyhedrons with rounded corners are also included. The reason why the diameter of the spherical body is 4 to 60 mm is 4
If the diameter is smaller than 60 mm, it is difficult to wipe, and if the diameter is larger than 60 mm, a chemical solution or the like is wasted. “Relatively low liquid absorption” and “relatively high liquid absorption” mean, of course, the relative relationship between the core material and the skin material.

[0007] The core material is not limited to a specific material,
It is preferable to be made of a foam of a soft resin, or a wrapped aggregate of fibers having a lower liquid absorbing property than cotton fibers or rayon fibers. The skin material is not limited to a specific material,
It is preferably made of a woven fabric, nonwoven fabric or wrapped aggregate of cotton fiber or rayon fiber, or a woven fabric or nonwoven fabric of a fiber having a lower liquid absorbing property than cotton fiber or rayon fiber.

[0008] Here, examples of the fiber having a lower liquid absorbing property than cotton fiber or rayon fiber include nylon fiber, polyethylene fiber and acrylic fiber.

The core material may be composed of a single layer or a plurality of layers having different materials or different densities. The skin material may be a single layer, but may be composed of a plurality of layers having different materials or densities.

The form of the wiping tool is not particularly limited, and examples thereof include a cotton ball composed of only a spherical body, and a cotton swab provided with a spherical body and a shaft having one end located substantially at the center of the spherical body. . It should be noted that the terms "cotton ball" and "swab" used in the present specification exclusively represent their forms, and the material is not limited to cotton. The use of the term "sphere" in addition to "cotton ball" is to further clarify that the invention is not limited to cotton.

The shaft may be a solid rod, but may be a tube having both ends opened, and a liquid injector for injecting a liquid into the other end of the tube may be provided so as to be insertable. . The inner diameter of the tube is not particularly limited, and can be selected from a wide range from a needle hole to a straw tube hole. If the inside diameter of the tube is small, a sudden flow of the liquid can be prevented, and if the inside diameter of the tube is large, the spherical body having a large diameter can quickly absorb the liquid.

As another embodiment of the shaft, a tube having an open end is provided integrally with a liquid injecting body for injecting a liquid into the other end of the tube. A tube provided with an opening / closing unit for opening and closing, or a tube having an open end, in which a liquid is sealed in the tube and provided with an opening / closing unit for opening / closing the flow of the liquid at an intermediate portion of the tube, can be exemplified. .

The opening / closing portion is not particularly limited, but may be, for example, a deformed portion formed by restorably deforming a middle portion of the pipe. Examples of the deformation mode include bending deformation, torsion deformation, and crushing deformation.
