ELECTRODE-TYPE SOLUTION MEASURING APPARATUS, STORAGE CONTAINER, AND ENDOSCOPE REPROCESSOR

摘要

In an electrode unit, a working electrode and a counter electrode are disposed in a cylindrical section having a cylindrical shape, which is a sensor main body, a distal end face of the working electrode is covered with a diaphragm that allows liquid to be measure to permeate, and an internal liquid chamber in which internal liquid of an electrolyte is stored and a standard solution chamber in which a standard solution for calibration is stored are partitioned by the diaphragm. The standard solution chamber is surrounded by an inner wall of the cylindrical section and a cap. When the electrode unit is mounted on a medical solution tank, zero adjustment is automatically performed using a standard solution inside the electrode unit. Thereafter, when the cap is opened, the standard solution is discharged and measurement in an actual use can be performed.

1. An electrode-type solution measuring apparatus comprising an electrode unit detachably attachable to a storage container that stores liquid to be measured, which is a measurement target,
the electrode unit including: a cylindrical section having a cylindrical shape detachably inserted into the storage container; a cap that openably closes a distal end portion of the cylindrical section with stress application; a diaphragm disposed a predetermined distance apart from the cap, the diaphragm selectively allowing the liquid to be measured to permeate; a standard solution chamber surrounded by an inner wall of the cylindrical section, the cap, and the diaphragm, the standard solution chamber storing a standard solution for calibration; a working electrode disposed in the cylindrical section to be set in contact with the diaphragm; a first electrode pad electrically connected to the working electrode and disposed on a surface of the cylindrical section; an internal liquid chamber partitioned from the standard solution chamber by the diaphragm in the cylindrical section, the internal liquid chamber storing internal liquid of an electrolyte; a counter electrode disposed to be separated from the working electrode in the cylindrical section, at least a part of the counter electrode being exposed in the internal liquid chamber to come into contact with the internal liquid; and a second electrode pad electrically connected to the counter electrode and disposed on the surface of the cylindrical section.
