Methods for driving an endoscope cleaning/disinfecting apparatus
An endoscope cleaning/disinfecting apparatus of the invention includes: a processing tank including an opening portion; an apparatus main body which performs processing on an endoscope arranged in the processing tank; a lid member which opens and closes the opening portion; an electric actuator which is connected to the lid member and which generates a pressing force for pressing the lid member toward the opening portion; and a control section connected to the apparatus main body and the electric actuator, the control section causing the electric actuator to continue to generate the pressing force for pressing the lid member toward the opening portion in a predetermined period during execution of the processing, and causing the electric actuator to stop generating the pressing force in a period other than the predetermined period.
1. A method of driving an endoscope cleaning/disinfecting apparatus, the endoscope cleaning/disinfecting apparatus comprising:
a processing tank having a concave shape and including an opening portion;
an apparatus main body;
a lid member which is disposed on the main body so as to be movable between a sealing position at which the opening portion is sealed and an open position at which the opening portion is open;
an electric actuator which is connected to the lid member and which generates a pressing force for pressing the lid member toward the opening portion; and
a control section connected to the apparatus main body and the electric actuator, the method comprising:
(a) processing an endoscope arranged in the processing tank using liquid;
(b) within a period of execution of the processing, generating the pressing force for pressing the lid member toward the opening portion for a portion of the period of execution to seal the opening portion, the portion of the period of execution being less than the period of execution; and
(c) within the period of execution of the processing, stopping generation of the pressing force for pressing the lid member toward the opening portion in a period other than the portion of the period of execution.
2. The method of driving an endoscope cleaning/disinfecting apparatus according to claim 1 , wherein
prior to step (b), the processing includes introducing the liquid into the processing tank, and the method further comprises:
determining whether a liquid surface in the processing tank is located higher than a position at which the lid member and the processing tank are in contact with each other;
wherein the portion of the period of execution in step (b) includes a period in which the liquid surface in the processing tank is determined to be located higher than the position at which the lid member and the processing tank are in contact with each other.
3. The method of driving an endoscope cleaning/disinfecting apparatus according to claim 2 , wherein the endoscope cleaning/disinfecting apparatus further comprises, an air compressor which introduces gas into the processing tank,
wherein prior to step (b), the processing includes introducing the gas into the processing tank by driving the air compressor, and the method further comprises:
determining whether an air pressure in the processing tank is higher than atmospheric pressure;
wherein the portion of the period of execution in step (b) includes a period in which the gas is introduced into the processing tank and the air pressure in the processing tank is determined to be higher than atmospheric pressure.
