する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug injection device for use in a drug dissolving device for automatically preparing a drug solution for supplying to a hemodialysis device used for treatment of renal failure or the like.

動している。2. Description of the Related Art A drug dissolving device has a hermetically sealed structure. A space between the medicine input port and the dissolution tank is also covered with a protective cylinder, and the protection cylinder is closely attached to the lid of the dissolution tank to shut off the input medicine and the dissolution liquid in the dissolution tank or the prepared chemical liquid from the outside air. The dissolution liquid in the dissolution tank is constantly stirred to promote dissolution of the drug and make the concentration of the drug solution uniform, and the dissolution liquid is flowing in the dissolution tank.

An air flow, that is, a wind is also generated in the protective cylinder, and the chemical agent input port is also affected by the wind, and the chemical agent falling from the input port to the dissolution tank is also affected by this wind. When the dissolution tank is cylindrical, it depends on the stirring method, but since the flow of the dissolution liquid is a circular flow along the inner wall of the dissolution tank, the air flow inside the protection cylinder also becomes a rotation along the inner wall of the protection cylinder. Is carried by the air flow and adheres to the inner wall of the protective cylinder. The protective cylinder is made of a transparent material so that the falling state of the drug can be visually observed, but if the drug loses its transparency and the amount of the drug adhered increases, it falls into the dissolution tank and changes the concentration of the drug solution. There is something to do. In particular, when a powdered medicine is used and the solution in the dissolution tank is heated, the influence is great, and it is necessary to manually clean every two months to remove deposits in the protective cylinder.

質でできたアダプターを装着する。[Means for Solving the Problems] In order to prevent the influence of wind on a drug falling from an input port, a shape having a partition effect is provided in a protective cylinder so as to cover the input port, for example, tetrafluoroethylene. Wear an adapter made of a non-hygroscopic material that does not allow powdered chemicals to adhere.

壁に当たるものは更に減少する。The medicine to be supplied to the dissolution tank is transferred in the protection cylinder by a medicine transfer device such as a screw or a stick, and is introduced into the dissolution tank from the introduction port at the tip of the protection cylinder. When the adapter that blocks the wind is installed in the protective cylinder, the wind speed in the protective cylinder is weakened, and the force received by the powdered drug falling in the protective cylinder is weakened. Thus, less powdered drug will be drifted down or will rotate. Further, since the adapter is attached so as to cover the charging port, the powdered medicine that is being made to flow downwind or is rotating is blocked by the adapter, and the amount directly hitting the inner wall of the protective cylinder is further reduced.

FIG. 1 is an embodiment, showing the vicinity of the insertion port and the protective cylinder to which the adapter 3 shown in FIG. 2 is attached, and a part of the protective cylinder is cut away. In FIG. 1, an adapter 3 is fixed to a tip of a charging cylinder 1 with a band 4 so as to cover a charging port 2.

【発明の効果】保護筒内壁に付着する薬剤が少なくなる
ため、溶解槽内の薬液濃度を変化させる薬剤落下を防止
するための、人手による清掃は６か月以上必要がなくな
る。EFFECTS OF THE INVENTION Since the amount of chemicals attached to the inner wall of the protective cylinder decreases, it is not necessary to manually clean the chemicals for more than 6 months in order to prevent the chemicals from dropping, which changes the concentration of the chemical in the dissolution tank.
【０００８】保護筒内壁に薬剤が付着しにくくなるた
め、溶解し易い微粉末薬剤を使用することが可能にな
り、薬剤の溶解速度が高くなるため、薬液濃度が非常に
安定したものとなる。Since it becomes difficult for the drug to adhere to the inner wall of the protective cylinder, it becomes possible to use a finely powdered drug that is easily dissolved, and the dissolution rate of the drug becomes high, so that the concentration of the drug solution becomes very stable.
