<p><P>PROBLEM TO BE SOLVED: To solve the problem that steel is oxidized by the medical solution and swollen to happen to cause wrong injection since a tee in a conventional eradication device is made of steel in many cases to be screwed to a medical solution inlet mounting part, that the tee is low in pipe resistance and causes pumped-up water to be apt to be laminar, the injected medical solution to be hard to mix, and residual chloride concentration to be wide in variation, and that impurities contained in pumped-up water reacts with the medical solution and adhered to the inlet. <P>SOLUTION: In the eradication device, a water connection through which water pumped-up from a lifting pump can be introduced, and which is corrosive is provided in the body. The inlet to enable the injection of the medical solution is arranged in the water connection. Additionally, the inlet is installed near a different diameter portion and near an elbow. A projection, etc. , are formed to cause turbulence at the upstream of the water connection inside of the inlet. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
