Endoscope reprocessing apparatus

1. An endoscope reprocessing apparatus, comprising:

a fluid supply conduit that supplies a fluid to at least one of a channel or an outer sheath of an endoscope;

a measurement section that measures a flow rate or a pressure of the fluid that flows through the fluid supply conduit;

an information accumulating section that accumulates the flow rate or the pressure which is measured by the measurement section as flow rate or pressure information associated with a measurement timing;

a prediction section that calculates a change-over-time prediction axis of the flow rate or the pressure from the flow rate or pressure information which is accumulated, when a predetermined number or more of pieces of the flow rate or pressure information are accumulated in the information accumulating section;

a threshold value determining section that determines whether the flow rate or pressure information which is measured by the measurement section is in a region in which the fluid supply conduit is determined to be clogged, of a region exceeding a predetermined threshold value and a region below the predetermined threshold value;

a correlation determining section that determines whether or not newest flow rate or pressure information that is measured by the measurement section has a correlation with the change-over-time prediction axis, when the threshold value determining section determines that the flow rate or pressure information is in the region in which the fluid supply conduit is determined to be clogged; and

a control section that performs a first measure relating to removal of scale when the correlation determining section determines that the newest flow rate or pressure information has the correlation, and performs a second measure different from removal of scale when the correlation determining section determines that the newest flow rate or pressure information does not have the correlation.

2. The endoscope reprocessing apparatus according to claim 1 , further comprising:

a notification section,

wherein the control section requests a user to introduce a chemical solution that removes scale into the fluid supply conduit by the notification section, as the first measure, and requests the user to check a filter by the notification section, as the second measure.

3. The endoscope reprocessing apparatus according to claim 1 , further comprising:

a removal chemical storing section that stores a removal chemical that removes scale,

wherein the control section introduces the removal chemical into the fluid supply conduit from the removal chemical storing section as the first measure.

4. The endoscope reprocessing apparatus according to claim 1 ,

wherein the prediction section resets the change-over-time prediction axis by setting a number of pieces of the flow rate or pressure information accumulated in the information accumulating section to zero, when the first measure is executed by the control section.

5. The endoscope reprocessing apparatus according to claim 1 , further comprising:

a detachably attachable pump that introduces a fluid into the fluid supply conduit,

wherein the prediction section resets the change-over-time prediction axis by setting a number of pieces of the flow rate or pressure information accumulated in the information accumulating section to zero with replacement of the pump, or performs correction of a gradient of the change-over-time prediction axis.

6. The endoscope reprocessing apparatus according to claim 1 ,

wherein when a number of pieces of the flow rate or pressure information is smaller than the predetermined number, and

the threshold value determining section determines that the flow rate or pressure information is in the region in which the fluid supply conduit is determined to be clogged,

the control section performs the second measure.

7. The endoscope reprocessing apparatus according to claim 1 ,

wherein the measurement section is a flow rate sensor or a pressure sensor.
