Abstract

An endoscope reprocessor includes a medicinal solution tank configured to store a medicinal solution; a first detachable portion provided in the medicinal solution tank and configured to detachably hold the concentration meter such that a measuring surface of the concentration meter is placed in the medicinal solution tank; a preserving fluid tank configured to store a preserving fluid of the concentration meter; and a second detachable portion provided in the preserving fluid tank and configured to detachably hold the concentration meter such that the measuring surface of the concentration meter is placed in the preserving fluid tank.

First claim

What is claimed is:

1. An endoscope reprocessor comprising:
a treatment tank for holding an endoscope;
a medicinal solution tank configured to store a medicinal solution, the medicinal solution tank being fluidically connected to the treatment tank by one or more fluid circuits;
a first detachable portion provided in the medicinal solution tank and configured to detachably hold a concentration meter such that a measuring surface of the concentration meter is placed in the medicinal solution tank;
a preserving fluid tank configured to store a preserving fluid of the concentration meter, the preserving fluid tank not being connected to output to or input from the treatment tank so as to be fluidically isolated from the treatment tank; and
a second detachable portion provided in the preserving fluid tank and configured to detachably hold the concentration meter such that the measuring surface of the concentration meter is placed in the preserving fluid tank.

2. The endoscope reprocessor according to claim 1 , further comprising:
a preserving fluid introduction portion configured to introduce the preserving fluid into the preserving fluid tank; and
a preserving fluid lead-out portion configured to lead out the preserving fluid from the preserving fluid tank.

3. The endoscope reprocessor according to claim 2 , further comprising:
a water filter configured to filter water;
a first water supply conduit configured to link a water supply source and the water filter;
and
a second water supply conduit configured to link the water filter and the treatment tank, wherein
the first water supply conduit includes the preserving fluid introduction portion, the preserving fluid tank, and the preserving fluid lead-out portion.

4. The endoscope reprocessor according to claim 3 , wherein
the preserving fluid introduction portion is placed at such a position that water discharged from the preserving fluid introduction portion falls into the preserving fluid tank;
the preserving fluid lead-out portion is tubular in shape, a first end portion of the preserving fluid lead-out portion opens in the preserving fluid tank while a second end portion of the preserving fluid lead-out portion opens at a lower position in a direction of gravity than the first end portion, and a tubular portion linking the first end portion and second end portion turns back at a higher position in the direction of gravity than an opening of the first end portion.

5. The endoscope reprocessor according to claim 1 , further comprising a temperature regulation unit configured to regulate a temperature of the preserving fluid stored in the preserving fluid tank.

6. The endoscope reprocessor according to claim 1 , further comprising the concentration meter.
