Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a germicidal mat, particularly a germicidal mat for hospital use.

[Conventional technology and its problems]

In clean zones such as hospital clean areas, biochemical factories, food manufacturing factories, semiconductor manufacturing factories, etc., the floor surfaces must be kept clean, and especially in hospitals, it is necessary to remove A and sterilize when people and equipment enter and leave the room. There is.

For this reason, a 9-mat is known in which a film is coated with an adhesive material mixed with a bactericidal agent and several layers of this are layered. With this product, a new adhesive surface appears when the film surface is somewhat dirty and the film itself is removed, but because it is in a dry state, it is effective in removing dust, but not in sterilization.

There are also fabrics, overlapping fabrics, or bag-like fabrics impregnated with a chemical solution, but these can be used to create wrinkles in people's feet, and friendships that cling to carts of utensils. I don't feel well. Moreover, the condition of the chemical solution is not uniform, making it difficult to obtain a uniform sterilizing effect.Furthermore, the floor becomes soaked with water, and the chemical solution evaporates rapidly, requiring frequent replenishment.

Another method known is to install a tank of chemical solution directly on the floor, but this poses many problems, such as people passing by and their belongings getting soaked with water, which limits footwear to rubber shoes, and construction costs. It gets heavy.

Is the present invention applicable to the above-mentioned conventional technique? /II0 Problems are solved, and a functional killing mat with a simple structure and lasting efficiency is provided.

[Means for solving the problem] The present invention is a sterilizing mat made of a nonwoven fabric and a nonwoven fabric or polymeric foam layer containing a superabsorbent polymer.

The nonwoven fabric that can be used in the present invention is one made of synthetic fibers such as polypropylene fibers and acrylic fibers, made into a nonwoven fabric by needle punching, etc., and has a thickness of 1 to 5 mm, preferably 5 to 4 mm. things are used.

Non-woven fabrics containing super-absorbent polymers include fibers made from super-absorbent polymers, fibers made of synthetic fibers made highly absorbent through post-processing, or R-knitted fabrics, such as shin woven fabrics made by needle punching, etc. A round type, a type in which a super absorbent polymer is sandwiched between two nonwoven fabrics made of ordinary fibers, or a type in which one side is bound with a sheet are used. A polymer foam layer may be used instead of or in combination with the nonwoven fabric containing a superabsorbent polymer. As the polymer foam, a foam of polyurethane, rubber, synthetic rubber, etc. is used, and the foam is cut into an appropriate thickness.

FIG. 1 shows a specific example of the present invention, in which (1) is a non-woven fabric, (2) is a super absorbent polymer T-rich non-woven fabric or a polymeric foam layer, which are integrated and molded with nine mats. For use, cut into appropriate sizes and add a pesticide.
Fill it with liquid II, place it on the floor at the entrance of the clean room, let anyone step on it, and let objects come into contact with it and pass through, killing the parts of people and objects that come into contact with the chemical solution.

If the floor is constructed of a material that dislikes moisture, a film or sheet (3) is applied under the nonwoven fabric or polymer foam j- containing a superabsorbent polymer and used as a water layer.

The present invention also includes storing the above-mentioned sterilizing mat in a storage part of a frame having a trapezoidal periphery.

FIG. 2 is a perspective view of the same, FIG. A sterilizing mat made of a nonwoven fabric (1), a nonwoven fabric containing an absorbent polymer, or a polymeric foam layer (2) is housed in the storage section (5). The frame (4) is made of rubber, synthetic rubber, or synthetic resin, and is designed in several shapes to prevent water leakage. Mat storage section (
The depth of 5) is about 5 to 10 mm, but it is better to set it as deep as the thickness of the mat to be stored.

A nonwoven fabric (2) containing a high molecular water absorbing polymer that constitutes the mat
) can be made to correspond to the height of the frame (4) if the chemical water becomes bulky. In addition, as will be described later, a round metal or synthetic resin net, grid, screen, or role as shown in Figure J14S is placed on top of the mat.

The size of the frame (4) is determined depending on the purpose of use and location, but generally the size of the frame (4) is 780 mm depending on the size of the storage section.
There are two types: 5m x 470cm and 1150cm x soo-. The paper surface of the storage section may be flat, but if #l (6) T- is provided in parallel or in a grid pattern as shown in Figure 84, the storage amount of the chemical solution can be increased and the number of times the drug solution needs to be replenished can be reduced. It is possible to keep the pine in a moist state for a long period of time, and it is continuously stable and reliably exhibits the 949-effect. The depth of 1111o should be about 5cm, the width 5cm, and the distance f44m. The four sides of the frame (4) are trapezoidal so that people can walk and objects, especially trolleys such as stretchers, can be smoothly moved onto the mat due to the slope of the trapezoid.

When the sterilizing mat of the present invention is used, the storage part (5) K of the Schiff V-me (4) is filled and stored with an appropriate amount of medicinal solution, and the mat is impregnated with it. To prevent excessive adhesion, place the above-mentioned net, lattice, screen, or board with holes on it.Auxiliary tool g: 9 shown in Figure 5. 0) is a bamboo shoot, ←)
(C) has a grid-like structure, and (C) has many holes formed in a synthetic resin plate.

[Example 1] Polypropylene fibers were needle-punched to a thickness of 3-
Underneath the non-woven fabric, there is a fiber containing a super absorbent polymer.
A sheet-like nonwoven fabric of "Lan Seal" (manufactured by Japan Exlan Kogyo Co., Ltd., water-absorbing fiber, trade name) was layered with a polyvinyl chloride film pasted thereunder, and processed into a size of 470 m x 840 m.

This mat was impregnated with about 800 d of an aqueous solution of L1% chloride gluconate (using Hypiden Gluconate solution (trade name), manufactured by British Industrial Co., Ltd.), and an average of about 50 people a day passed through it. The chemical solution still retained its wettability even after 5 days.
1) Perform antibacterial tests against representative bacteria using quantitative procedures. As a result, the class was canceled.

[Implementation row 2] A rubber frame with #11 provided on the bottom of the storage compartment in the shape shown in Fig. 4 was made by didle punching polypropylene fibers on a 3-inch thick polyurethane sponge.
Nine mats were stacked and processed into a size of 4,705 m x 840 cm, and then a synthetic resin net of the same size was layered on top of them.

Next, about 100,100 O of the sterilizing solution used in Example 1 was impregnated, and it remained wet even after 15 days with an average of 50 people passing through it per day. As in Example 1, an antibacterial test against representative bacteria was conducted using the bacteria reduction rate method, and almost the same results as in Example 1 were obtained.

[Effects of the Invention] The sterilizing mat of the present invention solves the problems of the conventional technology, has a simple structure, and maintains a moist state for a long period of time, so it can be used to kill 1 liter continuously and over a long period of time. It can also be used in bio-related factories, food manufacturing factories, and semiconductor factories.

The sterilizing mat of the present invention can be stably and reliably sterilized by allowing people passing by to step on it, and by passing objects in contact with the top surface of the mat. Furthermore, by placing the medicine in a frame, the amount of chemical solution can be increased, and evaporation and consumption can be reduced, resulting in a longer-term sterilization effect.
