る。2. Description of the Related Art Conventionally, absorbent cotton impregnated with a chemical solution is
It is used to sterilize the skin at the injection site. Further, it is also used for sterilizing and disinfecting the site by wiping off blood, pus, body fluid, etc. attached to the skin and mucous membranes. The reasons why absorbent cotton is used are that it is highly water-absorbent and easily absorbs and retains chemicals, has a good feel to the skin, and is made of natural cotton fibers, which is gentle to the human body.

綿繊維が単に集積されたものであるため、皮膚等を強く
擦ると、脱脂綿繊維が脱落して皮膚等に付着するだけ
で、血や膿等は除去されにくいのである。The absorbent cotton impregnated with the drug solution can be used without any particular problem as long as it sterilizes and disinfects the skin at the injection site, but blood and pus etc. adhering to the skin are wiped off and sterilized. In some cases, it was difficult to use. This is because the surface of the absorbent cotton is smooth and it is difficult to remove blood, pus, and the like. Since absorbent cotton is simply a collection of absorbent cotton fibers, when the skin or the like is strongly rubbed, the absorbent cotton fibers fall off and adhere to the skin or the like, and blood, pus, etc. are difficult to remove.

ので、皮膚等に付いた血や膿等を拭き取りやすくなるの
ではないかと、本件発明者等は考えた。For this reason, the inventors of the present invention considered using embossed absorbent cotton. The embossed absorbent cotton is obtained by passing absorbent cotton through an embossing roll to form a compressed portion and a non-compressed portion. Such embossed absorbent cotton is designed to reduce the bulkiness of the absorbent cotton and reduce its transportation cost. However, in the embossed absorbent cotton, the non-compressed part becomes a convex part,
The inventors of the present invention considered that it would be easier to wipe blood, pus, etc. adhering to the skin, etc., because the compressed part becomes a concave part and irregularities are formed on the surface of the absorbent cotton.

れていない脱脂綿と同様であった。However, it has been found that when the embossed absorbent cotton is impregnated with the chemical liquid, the compressed portion swells and the irregularities on the surface of the absorbent cotton tend to disappear. Therefore, it could not be expected that blood, pus, etc. on the skin would be easily wiped off. Even in the case of the embossed absorbent cotton, the absorbent cotton fibers are simply accumulated, so that the absorbent cotton fibers are likely to fall off and adhere to the skin or the like as in the case of non-embossed absorbent cotton.

Various studies were conducted. As a result, while entwining the absorbent cotton fibers with each other, a portion with a large amount of absorbent cotton fibers and a portion with a small amount are provided, and if a large portion is a convex portion and a small portion is a concave portion, it is possible to solve the above problems at once.

In the sterilized and disinfected cotton impregnated with a chemical solution, the absorbent cotton body has a large number of convex portions and concave portions connecting the convex portions, and the convex portions are formed by tightly entangled the absorbent cotton fibers with each other. On the other hand, the concave portion is formed of absorbent cotton fiber that connects the adjacent convex portions, and the amount of absorbent cotton fiber per unit area is smaller than that of the convex portion. It is a thing.

For example, a solution or an aqueous solution of isopropanol, ethanol, acrinol, benzalkonium chloride, benzethonium chloride, chlorhexidine gluconate, povidone iodine, tincture of iodo and the like can be used. Further, the impregnated amount of the chemical solution may be similar to the conventional one, and for example, the impregnated amount of 2.5 to 7.5 times the dead weight of the absorbent cotton body is preferable, and the impregnated amount of about 5 times is most preferable.

This means that the absorbent cotton fibers are positively entangled. Therefore, in the convex portion 1, the absorbent cotton fibers are tightly bound to each other, and the absorbent cotton fibers are less likely to fall off. The shape of the convex portion 1 may be arbitrary, and may be, for example, a square, a rectangle, a circle, an ellipse, a rhombus, a line, a ridge, or the like.

へ通過する等の点から、好ましいものである。A large number of convex portions 1, 1 ... Are connected by a concave portion 2. The concave portion 2 is formed of absorbent cotton fiber 3 that connects the adjacent convex portions 1 and 1. That is, one absorbent cotton fiber is present across the convex portions 1 and 1, and as a result, the convex portions 1 and 1 are connected by the absorbent cotton fiber. The absorbent cotton fibers in the recesses 2 are also generally entangled with each other. The absorbent cotton body is formed in a sheet shape as a whole. The concave portion 2 has a smaller amount of absorbent cotton fiber per unit area than the convex portion 1. In other words, the amount of absorbent cotton fiber per unit area of the convex portion 1 is larger than that of the concave portion 2. Such a configuration can be performed, for example, by moving the absorbent cotton fibers that originally existed in the concave portion 2 to the convex portion 1. Further, because of such a configuration, even if the chemical solution is impregnated, the concave portion 2 does not swell, and the unevenness of the surface can be maintained in the state of being impregnated with the chemical solution. In addition, a part of the concave portion 2 may have an opening portion in which the absorbent cotton fiber does not exist. If there is an opening, the drug solution can be held in this opening, and the liquid retaining property is improved. When removing blood, pus, etc., blood, pus, etc. pass to the outside from this opening. From the viewpoint of the above, it is preferable.

It is preferable that the sterilized and disinfected cotton of a fixed shape (for example, a square of 4 cm × 4 cm) has tens to hundreds of convex portions 1, 1, ... Specifically, the area of each convex portion 1 is preferably 0.5 to 6 mm 2 . When the area of one convex portion 1 is less than 0.5 mm 2 , the surface becomes smooth when the distance between the convex portions 1 and 1 is narrow, and when the distance between the convex portions 1 and 1 is wide, the convex portion 1 Does not work effectively, and the tendency to reduce the ability to wipe blood and pus. Also, one convex portion 1
If the area exceeds 6 mm 2 , the concave portions 2 are reduced, the unevenness is deteriorated, and the wiping property for blood, pus, etc. tends to be deteriorated. In addition, the number of the convex portions 1, 1 ...

The height of the concave portion 2 is preferably 0.5 mm or more lower than the height of the convex portion 1. Here, the height of the convex portion 1 refers to the distance indicated by h 1 in FIG. The height of the concave portion 2 means h 2 in FIG.
It means the distance shown in. Therefore, h 1 ≧ 0.8 mm and h 1 −h 2 ≧ 0.5 mm. Further, when obtaining the difference between the height of the convex portion 1 and the height of the concave portion 2, the difference between the heights of the convex portion 1 and the concave portion 2 which are close to each other is obtained. Further, even the concave portion 2 close to the convex portion 1 may be an open hole portion in which absorbent cotton fiber does not exist. In this case, the height of the concave portion 2 is 0 mm. If the height of the concave portion 2 is less than 0.5 mm less than the height of the convex portion 1, the unevenness is deteriorated and the wiping-off property for blood, pus, etc. tends to be deteriorated.

First, an absorbent cotton web in which absorbent cotton fibers are accumulated is prepared. Then, the absorbent cotton web is supported on the perforated support. As the perforated support, any support can be adopted, but, for example, a mesh fabric or the like is used. Then, a high-pressure water stream is applied from the absorbent cotton web side. The high pressure water stream then impinges on the absorbent cotton web and imparts kinetic energy to the absorbent cotton fibers. Due to this kinetic energy, the absorbent cotton fibers move in the direction of the holes of the perforated support while being entangled with each other. As a result, a absorbent cotton body is obtained in which the portions of the absorbent cotton web corresponding to the holes of the perforated support are convex portions, and the portions of the absorbent cotton web corresponding to the non-perforated portions having no holes are concave portions. Then, this absorbent cotton body is impregnated with a conventionally known chemical solution and cut into a predetermined shape,
Alternatively, it is cut into a predetermined shape and impregnated with a conventionally known chemical solution to obtain the sterilized and disinfected cotton according to the present invention.

られにくくなる。The size of the hole of the perforated support can be determined based on the size of the convex part of the absorbent cotton body to be obtained. For example, when using a mesh fabric,
Generally, a mesh fabric having openings (holes) of about 6 to 20 mesh is used. If the openings are less than 6 mesh, the pores are too large, and when a high-pressure water stream is applied, the absorbent cotton fibers flow out from the pores, making it difficult to form convex portions with a large amount of absorbent cotton fibers. When the mesh size is more than 20 mesh, the distance between the holes is too narrow, and the absorbent cotton fiber does not easily move to the holes of the holed support, and it becomes difficult to obtain the protrusions.

液性も良好となる。As can be seen from the results in Table 1, Examples 1 to 1
8 and the absorbent cotton body and sterilized and disinfected cotton obtained by the methods according to Reference Examples 1 to 3 have good liquid retention and fluffing properties and are suitable for use, and the loss of absorbent cotton fibers is reduced. I understand. Further, as can be seen by comparing the thickness of the absorbent cotton body with the thickness of the sterilized and disinfected cotton in which the absorbent cotton body is impregnated with the chemical solution, as compared with the case of the absorbent cotton in which the absorbent cotton fibers are simply accumulated, even when impregnated with the chemical solution, , Its thickness is hard to reduce. This is because the absorbent cotton fibers are tightly entangled and formed in the convex portion. Moreover, when comparing the results of Examples 1 to 8 and Reference Examples 1 to 3, in the case of Reference Examples 1 to 3, the difference in height between the convex portion and the concave portion and the area of the convex portion are It is smaller than that of 8. This is because, as the perforated support, those having a relatively large opening were adopted in Examples 1 to 8, while those having a relatively small opening were adopted in Reference Examples 1 to 3. That is, when the mesh size is large, the absorbent cotton fiber is more likely to move to the pores, resulting in a convex portion having a high height, and the area of the convex portion also increases. Further, for this reason, the difference between the convex portion and the concave portion also becomes large, and the chemical liquid is held there, so that the liquid retaining property becomes good.

Produce an effect. Further, in the convex portion and the concave portion, the convex portion has a larger amount of absorbent cotton fiber per unit area, and the concave portion has a smaller amount of absorbent cotton fiber per unit area. Therefore, even when impregnated with the chemical liquid, the concave portions are unlikely to swell, and a good uneven state is maintained. Therefore, when removing the blood, pus, and the like adhering to the skin by rubbing the skin, the removability is excellent.
