Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sterilizing mat for a clean room such as a hospital or a biochemical factory.

[0002]

[Prior art]

 In clean zones such as hospitals, semiconductor factories, and biochemical factories, it is necessary to keep the room and floor clean, especially for patients with infectious diseases. Since bacteria may be brought in by the dust, dust is prevented and disinfected when entering the room. However, the footwear of the occupants and the wheels of the dolly have been overlooked.

[0003] Therefore, it is known that a film is coated with an adhesive containing a bactericidal agent and is laminated in multiple layers, or a disinfection mat in which the film is stored in a frame. Although it is effective in removing dust, it is practically ineffective in sterilization.

[0004] Also known is a fabric such as a woven fabric or a non-woven fabric impregnated with a bactericidal agent, but it does not provide a sufficient bactericidal effect because it clings to a person's foot or a dolly of an implement. Moreover, the floor gets wet and it is necessary to replenish the bactericide frequently, which is not satisfactory.

[0005]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems of the prior art and provides a functional germicidal mat that exhibits a certain effect.

[0006]

[Means for Solving the Problems]

 According to the present invention, partitions 5 and 5 are provided in the housing portion 6 of the frame 1 and divided into three parts. The polymer foam sheet or artificial turf 2 is provided in the central portion, and the water absorbing sheets 3 are provided on both side portions. It is on a sterilization mat that stores

Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of one embodiment of the present invention, in which 1 is a frame, 2 is a polymer foam sheet or artificial grass, and 3 is a water-absorbent sheet.

The frame 1 is preferably made of rubber, synthetic rubber, or synthetic resin as a material and integrally molded so as to prevent the chemical liquid from leaking. The size is about 50 to 150 cm in width and 100 to 200 cm in length, depending on the purpose of use and the place of use. As shown in FIG. 2, the frame 1 has a slope 4 on its periphery so that people and wheels can easily pass therethrough. Further, as shown in FIG. 3, the storage section 6 is provided with partitions 5 and 5.

As the polymer foam sheet 2 used in the present invention, a foam such as polyvinyl alcohol, polyurethane, polyethylene, polystyrene, polyacrylonitrile, polyvinyl chloride, rubber, synthetic rubber can be used. Of these, it is particularly preferable to use a polyvinyl alcohol foam or a polyether urethane foam having excellent abrasion resistance and good water absorption.

In the present invention, artificial grass may be stored in place of the polymer foam sheet. As artificial turf, those made of vinyl chloride, vinylidene chloride, polyethylene, polypropylene, nylon and polyester are preferable.

The polymer foam sheet or artificial turf 2 is placed between the partitions 5 and 5 of the frame 1. The polymer foam sheet or artificial grass to be used has a thickness of about 1 to 5 mm and is used as it is, or is appropriately stacked.

A water absorbent sheet 3 is housed between the partitions 5 and 5 of the frame 1 and the frame, that is, on both sides of the foam sheet or artificial grass 2. As the water-absorbent sheet 3, non-woven fabric such as rayon fiber, cotton fiber, water-absorbent synthetic fiber such as acrylic fiber, fiber kneaded with antibacterial agent, and needle punching are used, and the surface thereof is used. A resin such as an acrylic acid polymer resin coated is preferably used. A few to ten or so sheets of water-absorbent sheets may be stored, and when the uppermost layer becomes dirty, it may be peeled off appropriately.

The back surface of the water-absorbent sheet 3 is preferably a resin film of polyethylene or the like, or a sheet laminated with a sheet. In this way, since they are stored in a stack, the lower layer will not get wet even if the uppermost layer gets wet due to use.

The sterilizing mat of the present invention is installed at the entrance and exit of an operating room or an intensive care unit of a hospital, and a sterilizing agent is applied to the central polymer foam sheet or artificial grass 2 housed in the frame 1. Place it by impregnating it by spraying or spraying. The contact surface of footwear such as patients, doctors and nurses, and equipment such as a trolley of a stretcher that enter through the room first passes over the water-absorbent sheet 3 in a dry state, and then the bactericidal agent. Bacteria adhering to the footwear and wheels are dedusted and sterilized by the sterilizing agent exuded from the polymer foam sheet or artificial turf 2 through the impregnated part of the water absorbent sheet. Sterilization in 3 Because the drug is absorbed, there is no contamination in the room by the occupants. Also, do not take bacteria out of the room when you leave the room. Furthermore, it does not get wet inside and outside.

In the sterilizing mat of the present invention, due to the cushioning property of the polymer foam sheet 2, the sterilizing agent spreads even in recesses such as grooves on the back of shoes such as shoes and slippers, so that sterilization is made more reliable. . In the case of artificial turf, it is even more effective to thoroughly clean the footwear and wheel grooves with the tips of the turf. Further, since the surface of the water-absorbent sheet 3 is coated with resin, no fluff is generated and the interior of the room can be kept clean.

The sterilizing mat of the present invention is designed so that when a person or a trolley passes over the polymer foam sheet or artificial turf 2 impregnated with a bactericidal agent, the polymer foam sheet or artificial turf 2 is framed. Either remove from the frame 1 to expose a new polymer foam sheet or two artificial grasses, or store in a new frame 1 and impregnate with a bactericide. It

The impregnation of the foam sheet or artificial turf 2 stored in the frame 1 with a bactericide is carried out by spraying, spraying, or sterilizing the foam sheet containing compartments of the frame 1 with a bactericide solution. Alternatively, the foam sheet or the artificial turf 2 may be placed and impregnated therein.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it is installed at the entrance and exit of the clean room, especially in the hospital room of patients with infectious diseases and the operating room of patients with infectious diseases. It is possible to surely sterilize the fungus attached to the uneven back surface of the footwear of the wearer, the groove of the wheel of the trolley on which the equipment is placed, and the like. Also, compared to conventional materials such as non-woven fabric, it does not become dust and scatter in the air and pollute the room.
