Abstract: A water quality measuring device comprises a measurement cell (10), a sample water supply unit (80), a reagent supply unit (30), an agitating unit (17), a measuring unit (20) and a control unit (90). The sample water supply unit (80) includes an inlet channel (12) configured to supply the measurement cell (10) with sample water and an outlet channel (13) configured to discharge sample water from the measurement cell (10). The inlet channel (12) is connected to a flow channel (2) configured to supply sample water, and includes a filter (13) and an electromagnetic valve (15). The control unit (90) opens the electromagnetic valve (15) for supplying sample water to allow sample water, from which foreign substances are removed by the filter (13), to flow into the measurement cell (10).

Abstract: A medicine package includes a container for containing a fluid medicine, a tube body for connecting an interior and an exterior of the container, a tube made of an elastic material, and a nozzle for discharging the medicine. The container is made of soft sheets each configured by laminating resin film layers and an aluminum foil layer, and provided as a bag having a gusset on either side. An inclined section is provided at an adhered section between the sheets such that an internal space of the container forms a funnel shape with the tube body as a stem.

Abstract: The present invention realizes a compact optical measuring device in which a sample solution sampling mechanism and a cleaning fluid producing mechanism are integrated with each other. Provided is an optical measuring device which applies light from a light emitting element to a sample solution in a measuring chamber provided in a measuring cell through a first light guide portion and which detects light from the sample solution by a light receiving element through a second light guide portion, including: a flow passage section formed in the measuring cell and adapted to guide the sample solution into or out of the measuring chamber; a flow control section attached to the measuring cell and serving to open and close the flow passage section; and a filtering section connected to the measuring cell and communicating with the measuring chamber.
