  At this time, the on / off valve 9 can finely adjust the amount of bath water introduced from the bath water circulation filtration system A (introduction communication portion 7A) into the container 6, so that the fine communication can be used for derivation communication. The amount of the bath water that has reacted with the drug 5 from the portion 7B (container 6) can also be finely adjusted. Therefore, for example, when sodium hypochlorite or the like that is highly toxic to the human body is contained in the container 6 and reacted with the bath water, the amount of bath water introduced into the container 6 is adjusted to a very small amount. By doing so, the amount of lead-out from the lead-out communicating portion 7B can be made very small, so that a large amount of bath water with high chemical concentration (containing chlorine) reacted with the chemical 5 flows out to the bath water circulation filtration system A. It can be prevented and danger can be avoided.

  Moreover, since the container 6 can see through the chemical | medical agent 5 inside, the replenishment time (decrease degree) of the chemical | medical agent 5 and the reaction condition of bath water and the chemical | medical agent 5 can be visually recognized.

  In the present invention, the medicine 5 can be replenished by opening the container 6 without shutting down the bath water circulation filtration system A by closing the on-off valve 9. Accordingly, the medicine 5 can be easily replenished, and the bath water circulation filtration system A is not stopped one by one, so that the operation efficiency of the system A is improved.

  Moreover, since the chemical injection device of the present invention has a configuration in which the container 6 is simply provided in the bath water introduction part 4, it can be miniaturized, and a small and easy-to-handle device can be realized.

  For example, when this chemical injection device is installed in the existing bath water circulation filtration system A, the drug injection device 14 provided in the existing bath water circulation filtration system A may not be used. 14 can be used in combination.

  That is, for example, as shown in FIG. 9, an appropriate medicine (agent A) is injected by the medicine injection device 14, and the medicine 5 (agent B) is also stored in the container 6 of the medicine injection device, It is also effective to construct a system in which these two types of chemicals react with an aqueous chlorine dioxide solution having a sterilizing and disinfecting action in, for example, bath water.

  Moreover, if it is set as the bath water circulation filtration system A which mixes such 2 types of chemical | medical agents, it will also become possible to select each chemical | medical agent, such as a diluted thing, without a danger to a human body, and handling of a chemical | medical agent. The effect that this is easily performed will also be exhibited.

At this time, the pressure in the container 6 is first lowered by the air vent valve 19, and then the opening / closing lid 6 </ b> B is opened to replenish the medicine 5 in the container 6.

  Moreover, since the transparent container 6 can see through the chemical | medical agent 5 inside, the replenishment time of the chemical | medical agent 5 and the reaction condition of the bath water and the chemical | medical agent 5 can be visually recognized.

  Further, the introduction amount of the bath water introduced into the container 6 from the introduction communication portion 7A can be finely adjusted by the introduction opening / closing valve 9A, and the pipe 12A (bath water circulation filtration) is introduced from the discharge communication portion 7B by the discharge opening / closing valve 9B. Since the amount of sterilized and disinfected bath water to the system A) can be finely adjusted, for example, sodium hypochlorite that is highly toxic to the human body is contained in the containing body 6 and bath water and In the case of reaction, the amount of bath water introduced into the container 6 is adjusted to a very small amount so that the bath water reacted with the chemical 5 (containing chlorine) does not flow out to the bath water circulation filtration system A in a large amount. Because it can be drained little by little, danger can be avoided.

  Moreover, the chemical injection device 14 installed in the existing bath water circulation filtration system A can also be used, and this is very effective because it is not necessary to use a stock solution of a drug harmful to the human body.

  That is, in the case of the existing bath water circulation filtration system A, the circulating bath water was sterilized and disinfected by injecting, for example, a sodium hypochlorite stock solution from the chemical injection device 14, Hazardous in handling sodium chlorate.

  In this regard, the drug injection device of the present embodiment is used.
