20080295615 | Water quality sampling system - A method and system are provided in which a water sensing device is equipped with a water-sealed sampling chamber enclosing the sensing probes of the sensing device. When the device is placed into its water habitat, water flow into and out of the sampling chamber is controlled such that water is present in the sampling chamber only during a relatively brief period of time when water quality measurements are taken by the probes. After the water quality measurements have been taken by the probes, the water sample is substantially pumped out of the sampling chamber so as to minimize the time during which the probes are in contact with the water being analyzed. | 12-04-2008 |

20120000297 | LIQUID COLLECTING SYSTEM AND A METHOD THEREFOR - A blood collecting apparatus includes a cleaning solution piping. The cleaning solution piping feeds into a flow path a heparin solution which is a liquid other than blood to be measured, in order to return the blood present in the flow path to a catheter disposed upstream of a blood inlet of the flow path. Thus, the blood having flowed into the flow path in an amount more than is necessary for blood collection, which corresponds to a portion returned to the upstream catheter of the blood to be measured present in the flow path, can be used in a next blood collection. As a result, the amount of collected blood can be reduced. The liquid to be measured is separated apart by means of a gas, and the flow path is cleaned in a way to leave no impurities in the flow path, thereby preventing impurities from mixing into the liquid to be measured. | 01-05-2012 |
