Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a water filtration agent used in domestic water supply and hot water supply systems to improve water quality and prevent corrosion of piping equipment.

BACKGROUND OF THE INVENTION Various chemicals are used to improve water quality and prevent corrosion of pipes, etc. Among them, phytic acid is highly safe, as it is used as a food additive, and its anticorrosion effect is also excellent, making it known as an excellent water treatment agent. Regarding this, US Patent No. 2,626,238, Japanese Patent Publication No. 44-1

Prior art has been disclosed in No. 2773 et al.

Problems to be Solved by the Invention The most important thing to keep in mind when treating water in a water supply and hot water supply system is ensuring safety for the human body. For this purpose, it is extremely important to select a water treatment agent and to add it to water in a hygienic manner. To prevent bacteria and other harmful substances from entering the water supply, it is desirable to add chemicals in a closed system that is isolated from the outside world. In a commonly used combination system of a chemical solution tank and an injection device, it is difficult to completely prevent contaminants from entering the drug solution tank when the drug is loaded into the drug solution tank. Since the amount of water treatment agent used in domestic water supply and hot water supply systems is relatively small, the chemical container can also be used as the chemical tank. In this case, it can be used only to connect the drug container and the injection device, which is useful for preventing contamination. However, drugs are usually distributed in bottles or cans, and there are problems with using them as they are.

First, it is impossible to create a completely sealed system. Containers such as bottles or cans are rigid and do not communicate with the outside air and cannot discharge their contents. For this purpose, an opening of some kind is required, and a filter or the like must be installed to prevent contamination through this opening. The second point is that containers such as cans are opaque, and it is necessary to install a liquid level measuring device to determine the amount of drug remaining during use. There is a need in this field to develop a container that can also be used as a chemical liquid tank and solves these problems.

Means for Solving the Problems As a means for solving the first problem, there is a method of continuously varying the internal volume of the container. This purpose can be most easily achieved by manufacturing the container from a flexible material and having a structure that deforms depending on the amount of liquid inside. In other words, a bag-shaped container made of a flexible material such as soft polyvinyl chloride or a balloon-shaped container are recommended as the simplest ones.

Such a container can also solve the second problem at the same time.

That is, the remaining amount of the drug can be easily determined as the deformation of the container, and this is sufficient to determine when to replace the container.

Further, it is convenient for use to attach a soft tube to the mouth of the container in advance. That is, during use, the tube can be directly connected to the chemical injection device, and contamination can be prevented as much as possible.

Furthermore, it is preferable to package the water treatment agent sealed in this container in a box with a window, such as a cardboard box with a hole partially punched. Even when used in the box, the remaining amount of the drug in use can be easily checked visually or tactually through the window, and the container can be protected, which is extremely convenient in practice.

The water treatment agent of the present invention is obtained by sterilizing the deformable container and enclosing a sterilized clean water treatment agent therein.

Function: When the container water treatment agent of the present invention is used, the mouth or pipe portion of the container is connected to the liquid supply port of a chemical liquid injection device. The container water treatment agent of the present invention does not come into contact with outside air during use, and can maintain a clean state until the end of use. The container of the present invention can deform according to the amount of medicine used and can effectively discharge the medicine. For example, a bag-shaped container becomes gradually flattened and deformed until it becomes flat as the medicine inside is used. Further, in a balloon-shaped container, a dent is formed in a part of the container, and this dent increases until it finally deforms into a bowl-shape. In either case, the drug content can be sufficiently discharged.

As described above, the action of the water treatment agent in a bag-like container according to the present invention is very similar to that of an injection agent packed in a bag-like container such as a blood bag for blood transfusion in the medical field. These pharmaceuticals and the drug of the present invention are also the same in that strict hygiene precautions are required at each stage of their manufacture, distribution, and use. However, the former usually has an internal capacity of 200 to 500 m1, and the maximum is 27! There is nothing that can surpass it. In contrast, the drugs of the present invention usually have a large capacity of 5 Il to 20 Il. Furthermore, the fields of application of the former and the drug of the present invention are completely different. The present invention will be explained in further detail with reference to Examples below.

Example 1 Water treatment agent for bag-shaped containers (1) Production of drug containers A soft polyvinyl chloride sheet with a thickness of 0.4 mm was
Cut into a rectangular shape with a width of 30 cm and a width of 30 cm, stack two sheets, and fill 1/3 of the short side with liquid to a length of 10 cm.
m, outer diameter 131 m, inner diameter 101 m, and a soft polyvinyl chloride pipe with length 8 Q cm, outer diameter 5 mm, inner diameter 4 vavs for drainage in the other 1/3 part of the surrounding area. It was inserted 2.5 cm perpendicular to the side and sealed around all four sides. The side into which the tube was inserted was 2.5 cm deep and was sufficiently sealed to obtain a bag-shaped container with a bone.

(2) Filling with medicine After thoroughly sterilizing this bone-in bag-like container using ethylene oxide, sealing the end of the drainage pipe and thoroughly removing the gas inside, use a 20% aqueous phytic acid solution as a water treatment agent. The sample was sterilized using a sterilizing filter and charged into the 5e from the filling pipe opening. After the charging was completed, the end of the tube was sealed to obtain a treatment agent for water entering the container according to the present invention.

(3) Pharmaceutical packaging A flat cardboard box with a length of 4Qcm, a width of 25cm, and a height of 5.5cm.The center line is 8cm away from the base of the top lid (in the vertical direction) and the length]Ocm, Ij]2°5cm Open two windows vertically, and 3 cm horizontally from the part 6 cr Il away from the base of the -I-lid on the shorter side plate.
The container water treatment agent was stored in a packaging box with one r112.5 cm window open, and a cardboard board of approximately the same size as the top lid and side panels was placed to protect the window, and the lid was closed and packaged.

(4) Use of the drug The drug package was opened at the place of use, the protective cardboard piece was removed, and the drainage tube was pulled out from the window in the side panel.

After disinfecting the end of the pipe, it was cut and connected to the liquid supply port of the chemical injection device to add the water treatment agent to the water supply. The top lid of the packaging box was closed, and the remaining amount of the drug was observed through the window every morning thereafter. After one week, the amount of remaining liquid became very small and the drug container was deformed into a substantially flat state. Work continued while paying close attention to the amount of remaining liquid, and when the liquid reached a state where it was almost empty, it was replaced with a new chemical. The amount of remaining liquid in the used drug container is approximately 30ml
It was in a state where it was fully used up for practical purposes.

Effects of the Invention The container water treatment agent of the present invention has sufficient hygienic considerations at each stage of its production, distribution, and use, has good storage stability, and can safely achieve the purpose of water treatment.

In addition, it can be used to connect a drip tube (chamber) used for patient infusion to the middle of the vinyl tube for drainage of drug containers in order to monitor the injection status of drugs, and can also be adapted to the liquid supply ports of various drug injection devices. It is more convenient to use the tube if a connecting adapter with an internal diameter of 6 to 101 m is attached to the end of the tube.

As described above, the present invention has a great advantage in that it can provide an excellent water treatment agent for water supply systems in buildings, hotels, hospitals, etc.
