[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to patient room furniture such as beds, chairs or side tables used in patient rooms.

[0002]

[Prior art]

 For example, bed room furniture such as beds used in hospitals and the like has not been conventionally subjected to antibacterial treatment. In recent years, nosocomial infection due to resistant Staphylococcus aureus (MRSA) has become a problem. Preventive measures against nosocomial infections include isolation of patients to prevent contact infections, disinfection of hands and clothes of doctors and nurses being treated, disinfection of hospital room floors, and disinfection of equipment that patients contact. . To disinfect the hands and clothes of doctors and nurses, the hands are washed with ethanol and the clothes are sprayed with ethanol. For disinfecting the floor of the hospital room, wipe disinfecting with a mop soaked in diamitol, disinfecting equipment contacted by the patient, such as mattress, curtain, etc. disinfecting with ethanol powder mist during replacement, bed frame, chair, or side table etc. As for the equipment, disinfection by wiping with alcohol gauze soaked in ethanol and disinfection with ethanol powder mist were performed. However, due to problems such as delayed detection of patients infected with resistant Staphylococcus aureus (MRSA) and incomplete detoxification of the areas contacted by patients due to lack of personnel, hospitalization with resistant Staphylococcus aureus (MRSA) The problem of infection has not been resolved.

Therefore, in recent years, bedding and curtains such as lab coats, mattresses, sheets, etc. have been subjected to an antibacterial treatment to prevent the adhesion of resistant Staphylococcus aureus (MRSA). Examples of antibacterial treatment for lab coats, bedding and curtains include blending chemical fiber raw materials such as rayon and polyester with an antibacterial agent, and using cloth made from this fiber to make bedding and curtains such as lab coats, mattresses and sheets. is there. The conventional antibacterial agents are antibacterial agents composed of organic compounds used for dust collector paper packs, socks, toothbrushes, etc. of vacuum cleaners, and antibacterial agents composed of silver ions containing crystal water and inorganic compounds. Is used. However, since an antibacterial agent composed of an organic compound is an organic system that is weak to heat, it may elute or volatilize.Antibacterial agents composed of silver ions containing water of crystallization and an inorganic compound are It has a big and uncomfortable feel. At the same time, when heated, the water of crystallization contained in the antibacterial agent is liberated, the silver ions become unstable, and since they darken over time, the external appearance is impaired. However, since the frame part of the bed that the patient contacts and other furniture such as chairs and side tables have not been subjected to antibacterial treatment, wiping disinfection with alcohol gauze dipped in conventional ethanol and ethanol powder mist Is being disinfected.

[0004]

[Problems to be solved by the device]

 As mentioned above, bed frames, chairs, and furniture for hospital rooms such as side tables have not been subjected to antibacterial treatment, so they are wiped and disinfected with alcohol gauze dipped in ethanol. There is a problem that the part contacted by the patient may not be completely disinfected due to lack of nurses due to insufficient number of nurses, etc., and along with this, the appearance may be impaired by wiping disinfection with alcohol gauze and the paint peeling off. There was such a problem. In addition, disinfection with ethanol dust requires a large amount of disinfection, which is only possible when disinfecting the entire hospital room. Further, conventionally, an organic antibacterial agent used as an antibacterial agent may cause elution, volatilization, etc., and an antibacterial agent composed of a silver ion containing crystal water and an inorganic compound has large particles of the antibacterial agent, and thus has a touch to the touch. However, it is not suitable for furniture for hospital rooms because the antibacterial effect cannot be obtained sufficiently if the compounding ratio of the antibacterial agent is decreased to prevent it, or the appearance is deteriorated due to darkening.

The present invention is intended to solve such problems, and provides a furniture for a patient room in which a sufficient antibacterial effect is obtained and an antibacterial coating film having excellent resistance is formed. With the goal.

[0006]

Means for Solving the Problems In order to achieve the above object, the hospital room furniture of the present invention has a coating film formed using a synthetic resin containing an antibacterial agent composed of an inorganic compound.

[0007]

[Action]

 The hospital room furniture of the present invention prevents the growth of bacteria such as adherent resistant Staphylococcus aureus (MRSA) by forming a coating film of synthetic resin containing an antibacterial agent. When the antibacterial agent is made of an inorganic compound, the compounding ratio of the antibacterial agent can be increased and a sufficient antibacterial effect can be obtained.

[0008]

【Example】

 An embodiment of the hospital room furniture of the present invention will be described below. The hospital room home appliance of this embodiment is a metal bed frame 1 used in a hospital as shown in FIG. A coating film 3 of synthetic resin mixed with an antibacterial agent 2 made of an inorganic compound is formed on the entire surface of the bed frame 1. The antibacterial agent 2 is a very stable inorganic compound of silver ions containing no water of crystallization and an inorganic ion exchanger. The silver ion, which is a complex contained in this antibacterial agent 2, changes the permeability of the cell membrane of bacteria and the like to prevent the growth of bacteria. The synthetic resin is polyester.

Next, the coating method of this embodiment will be described. First, the antibacterial agent 2 is mixed with the polyester powder in a weight ratio of about 2%. Then, when the powder of the polyester containing the antibacterial agent 2 is charged with static electricity and jetted toward the grounded bed frame 1, the powder of the polyester containing the antibacterial agent 2 is electrostatically applied to the bed frame 1. Evenly adheres to the surface. Then, the bed frame 1 is put into a baking and drying oven and heated to about 200 ° C. to melt the powder layer to form a uniform coating film 3. Thus, a uniform coating film 3 made of polyester containing the antibacterial agent 2 is formed on the entire surface of the bet frame 1.

According to the bed frame 1, the coating film 3 containing the antibacterial agent 2 prevents bacteria such as resistant Staphylococcus aureus (MRSA), which is said to be a cause of nosocomial infection, from contacting a patient or disinfecting a doctor or a nurse. Propagation of attached bacteria can be prevented by contact with fingers. Since the antibacterial agent 2 is made of an inorganic compound of silver ions and an inorganic ion exchanger, the compounding ratio of the antibacterial agent 2 can be increased to about 2% and a sufficient antibacterial effect can be obtained. Further, since it is the inorganic antibacterial agent 2, it can be heated to about 200 ° C. during coating as described above, and thus the synthetic resin for the coating film 3 can be made into a polyester having a high melting temperature. Since the coating film 3 is made of polyester, the durability and the like are increased.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made. For example, although the weight ratio of the antibacterial agent in the coating is set to 2% in the above embodiment, the compounding ratio is not limited thereto. Generally, in order to obtain a sufficient antibacterial effect, it is preferably 1% or more, and up to 3% is sufficient. Epoxy acrylic polyamide can also be used as the synthetic resin.

[0012] Coating forms a coating film by applying or spraying the coating on a solid surface. Generally, the purpose is to preserve things (preservation, rust prevention, insect repellent, fire protection) and decoration. Is brush painting, air spray painting in which the paint is sprayed with compressed air to form a mist, airless spray painting in which high pressure is applied to the paint without using compressed air, and sprayed from a small hole. Flow coat coating, in which the object to be coated is applied by a conveyor, electrostatic coating in which the fog of the paint is electrostatically absorbed and adheres to the object to be coated, and the object to be coated is used as an anode by immersing the object in the electrodeposition coating tank. Immediately after spraying paint by applying a direct current between the cathode and cathode to form a paint film on the surface of the object, and by applying static electricity and air pressure to the powder paint on the object to be painted in the paint booth. For example, there is powder coating for baking.

In the above-mentioned embodiment, the coating method is not limited to electrostatic powder coating as in the above-mentioned embodiment, but a powder of synthetic resin such as polyester or epoxy resin mixed with the antibacterial agent 2 is placed in the coating booth. The bed frame 1 heated by the air flow and heated above the softening point of the synthetic resin is put in this coating booth, and the synthetic resin mixed with the antibacterial agent 2 is fused to the antibacterial agent 2 on the entire surface of the bed frame 1. Fluidized dipping coating may be used to form a uniform coating film 3 made of synthetic resin such as polyester or epoxy resin. Further, a method of applying a liquid and curing the liquid is also preferable. In this method, epoxy resin or the like can be used. There are various methods of coating with an epoxy resin. For example, a liquid epoxy resin in which a curing agent is mixed and the antibacterial agent 2 is kneaded is applied, and then heated to be cured.

Further, in the above-mentioned embodiment, the bed is taken as an example of the furniture for the patient room, but the present invention is also applicable to various kinds of furniture for the patient room such as a chair or a side table used in the patient room.
