Also, use is performed regardless of a place by attaining a tank system and a multi-power-source system and an operation is easily and sanitarily performed by anyone by making both of hand pressing and foot stepping possible for an ejection pump switch.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical and sanitary washer and apparatus, and more particularly to a bacterium and the like which are harmful to humans and animals due to a liquid such as a cleaning / disinfecting solution or strong acid water using a discharge pump and a flow control system. Electronics for sterilizing microorganisms,
Related to medical equipment.

[0002]

2. Description of the Related Art In general, medical and sanitary washing utensils are provided with sanitary equipment such as a washbasin or the like and a chemical-filled container, or a disinfecting / sterilizing agent described in a dispensing guideline, for example, a cresol soap mixed solution. A solution containing tincture, diluted iodine tincture, a surfactant, 70% ethanol, isopropanol, chlorhexidine, etc. is placed in a washbasin such as alumite or stainless steel, placed on a dedicated stand, or placed on a side table of a consultation table. Even under the Food Sanitation Law, hand washing equipment is obligatory, and in most cases, running water after chemical application is of the type directly connected to tap water.

[0003]

[Problems to be Solved by the Invention] However, although the amount of cleaning and disinfecting agents prescribed for medical use is small, most of them are dangerous substances and powerful drugs.・ It causes rash and dermatitis to the arms, etc., and causes irritable skin and allergy. In addition, the used waste liquid needs to be dealt with by a special treatment method for dangerous substances, deleterious substances and special reagents, even if there is no problem because bacteria and microorganisms have been killed by chemicals. Further, in the case of a gantry type washing machine or the like, there is a danger that the chemical solution may fall over and be scattered on the floor and the surroundings due to a step on the floor or clothes being caught when moving. Many of these drugs not only damage fingers and the like when used frequently, but also cause acute poisoning, pulmonary edema and inflammation of mucous membranes such as eyes and mouth when inhaled before dilution or during preparation. Simple hand-washing equipment for food hygiene is installed in cooking places such as school lunches, hospitals and restaurants, but only in places where raw food is handled, unwashed chemicals and recontamination with tap water pose problems. ing. Wastewater containing chemicals from these kitchens flows directly into the sewage, increasing the burden on sewage treatment plants and causing environmental pollution. To solve these problems,
In recent years, there have been some products that use electrolyzed water that is returned to the original water when exposed to air, heat, or light for a long time, and that is directly connected to the water supply. Even if it is improved, there is a problem that the energy saving concept of the minimum amount of use is insufficient due to the spray method, or a sufficient amount of liquid cannot be obtained due to the atomization, and the disinfection effect is reduced by half. The present invention solves the above-mentioned drawbacks by designing a discharge port so that fingers and the like can be efficiently and evenly cleaned with a minimum amount of fluid as much as possible, and damages such as environmental pollution and drug sensitivity caused by the cleaning fluid. The present invention provides a new style of cleaning device that has been designed to minimize the risk of inconvenience and has a configuration that is easy for the user to use.

[Action]

1) A discharge object having a hemispherical convex surface shape in the discharge direction and discharge holes arranged radially concentrically can clean an object to be cleaned evenly over a large area. 2) By providing water supply / drainage tanks of different colors, the cleaning fluid can be installed without misunderstanding. 3) By adopting both the hand-operated type and the foot-operated type as the discharge switch, the operation can be easily performed with the foot even when the back of the hand is used or both hands are occupied, which is hygienic. 4) In addition to the DC power supply, a rechargeable battery system has been adopted, so that the power supply cannot be used by other devices, or to be used in emergency wards other than in isolated wards and normal installation locations, and for mobile ambulances.・ Can be used as a disinfection device. 5) By providing the casters with stoppers at the four corners, the load on the device can be equalized and the device can be easily moved when moving. In addition, the multi-power system and movable mechanism described in the preceding paragraph enable mounting on mobile vehicles such as ambulances and camping cars. 6) The use of a corrosion-resistant coating on piping and panels that are normally exposed to the cleaning liquid improves the storage stability of the device. 7) By using the acidic water generated on the anode side of the electrolysis water as the cleaning liquid, it is possible to perform cleaning and disinfection without using a chemical agent and without adversely affecting humans and animals and the environment. In addition to the above functions and effects, by using a flow path switching valve as shown in the embodiment below, it becomes possible to realize a large cleaning object other than fingers and utensils and active cleaning / sterilization outdoors. Was. The use of a tank type in this washer is mainly for supplying water to a place far from the electrolysis water generator or for use in a location that is frequently moved.However, when fixing the installation location, use a wastewater tank. As it is,
Normally, it can be discharged to sewers. However, especially when used for medical clinical and research disinfection and disinfection, disposal of used water in wastewater tanks should be considered for disposal to appropriate wastewater treatment facilities.
