Abstract

An endoscope reprocessor includes a control section and a flow liquid pump. The control section controls a plurality of electromagnetic valves to set a first drive state, in which the control section puts a first cleaning tube connected to a suction pipe sleeve of an endoscope into a sealed state, the control section puts a second cleaning tube connected to a forceps plug pipe sleeve of a forceps plug of the endoscope into an unsealed state, the control section controls an electromagnetic valve configured to switch a state of a connector plugging a suction cylinder of the endoscope to put the connector into a sealed state, the control section sets a state in which a fluid is supplied from the flow liquid pump to the first cleaning tube, and the control section halts supply of the fluid from the flow liquid pump to the second cleaning tube.

First claim

What is claimed is:

1. An endoscope reprocessor comprising:
a first connection connector to which a first cleaning tube is attached, the first cleaning tube being connected to a suction pipe sleeve of an endoscope and capable of being switched between a first sealed state in which an entire amount of a first fluid is introduced into the suction pipe sleeve and a first leak state in which the first fluid is introduced into the suction pipe sleeve and a first predetermined amount of the first fluid is leaked to an outer circumference of the suction pipe sleeve, wherein the first cleaning tube comprises a first connector supplied with a first air, the first connector entering the first sealed state by sealing a passage between the suction pipe sleeve and the first connector and entering the first leak state in which the first fluid is leaked from between the suction pipe sleeve and the first connector to the outer circumference by not sealing the passage between the suction pipe sleeve and the first connector;
a first valve configured to control a supply of the first air so that the first connector is put into the first sealed state or the first fluid is leaked from between the suction pipe sleeve and the first connector to the outer circumference, to switch between the first leak state and the first sealed state of the first cleaning tube;
a first pump configured to supply the first fluid from the first connection connector to the suction pipe sleeve through the first cleaning tube;
a second connection connector to which a second cleaning tube is attached, the second cleaning tube being connected to a forceps plug pipe sleeve of the endoscope and capable of being switched between a second sealed state in which an entire amount of a second fluid is introduced into the forceps plug pipe sleeve and a second leak state in which the second fluid is introduced into the forceps plug pipe sleeve and a second predetermined amount of the second fluid is leaked to an outer circumference of the forceps plug pipe sleeve, wherein the second cleaning tube comprises a second connector supplied with a second air, the second connector entering the second sealed state by sealing a passage between the forceps plug pipe sleeve and the second connector and entering the second leak state in which the second fluid is leaked from between the forceps plug pipe sleeve and the second connector to the outer circumference by not sealing the passage between the forceps plug pipe sleeve and the second connector;
a second valve configured to control a supply of the second air so that the second connector is put into the second sealed state or the second fluid is leaked from between the forceps plug pipe sleeve and the second connector to the outer circumference, to switch between the second leak state and the second sealed state of the second cleaning tube;
a second pump configured to supply the second fluid from the second connection connector to the forceps plug pipe sleeve through the second cleaning tube;
a third valve configured to control a supply of a third air to switch a third sealed state and a third leak state of a third connector plugging a suction cylinder of the endoscope, wherein a third fluid is not leaked from the suction cylinder in the third sealed state, and a third predetermined amount of the third fluid is leaked from the suction cylinder in the third leak state; and
a controller configured to control the first valve, the second valve, the third valve, the first pump, and the second pump to set a first drive state, in which
the controller controls the first valve to put the first cleaning tube into the first sealed state,
the controller controls the second valve to put the second cleaning tube into the second leak state,
the controller controls the third valve to put the third connector into the third sealed state,
the controller sets a state in which the first fluid is supplied from the first pump to the first cleaning tube, and
the controller sets a state in which supply of the second fluid from the second pump to the second cleaning tube is halted.

2. The endoscope reprocessor according to claim 1 , wherein
the controller controls the first valve, the second valve, the third valve, the first pump, and the second pump to set a second drive state, in which
the controller controls the first valve to put the first cleaning tube into the first sealed state,
the controller controls the second valve to put the second cleaning tube into the second sealed state,
the controller controls the third valve to put the third connector into the third sealed state,
the controller sets a state in which the supply of the first fluid from the first pump to the first cleaning tube is halted, and
the controller sets a state in which the second fluid is supplied from the second pump to the second cleaning tube.

3. The endoscope reprocessor according to claim 1 , wherein
the controller controls the first valve, the second valve, the third valve, the first pump, and the second pump to set a third drive state, in which
the controller controls the first valve to put the first cleaning tube into the first leak state,
the controller controls the second valve to put the second cleaning tube into the second leak state,
the controller controls the third valve to put the third connector into the third leak state,
the controller sets the state in which the first fluid is supplied from the first pump to the first cleaning tube, and
the controller sets the state in which the supply of the second fluid from the second pump to the second cleaning tube is halted.

4. The endoscope reprocessor according to claim 1 , wherein
the controller controls the first valve, the second valve, the third valve, the first pump, and the second pump to set a fourth drive state, in which
the controller controls the first valve to put the first cleaning tube into the first leak state,
the controller controls the second valve to put the second cleaning tube into the second leak state,
the controller controls the third valve to put the third connector into the third leak state,
the controller sets the state in which the supply of the first fluid from the first pump to the first cleaning tube is halted, and
the controller sets the state in which the second fluid is supplied from the second pump to the second cleaning tube.

5. The endoscope reprocessor according to claim 1 , wherein
the controller controls the first valve, the second valve, the third valve, the first pump, and the second pump to set a fifth drive state, in which
the controller controls the first valve to put the first cleaning tube into the first leak state,
the controller controls the second valve to put the second cleaning tube into the second leak state,
the controller controls the third valve to put the third connector into the third leak state,
the controller sets the state in which the first fluid is supplied from the first pump to the first cleaning tube, and
the controller sets the state in which the second fluid is supplied from the second pump to the second cleaning tube.
