Abstract: A control method for an endoscope reprocessor is a control method for an endoscope reprocessor that includes a treatment tank, a circulation conduit that links a circulation opening and a discharge opening opened in the treatment tank to each other, a first pump that feeds liquid from the circulation opening towards the discharge opening, an atmospheric open conduit including a first end portion open to an atmosphere and a second end portion connected between the circulation opening and the first pump in the circulation conduit, a filter that filtrates a liquid flowing from the treatment tank through the circulation opening into the circulation conduit, and a sensor that detects a liquid feeding state in the circulation conduit, where the liquid feeding state in the circulation conduit is measured by the sensor during operation of the first pump in a state where the inside of the atmospheric open conduit is closed.

Abstract: A connector functioning as an endoscope connector includes an outer cylinder member, an inner cylinder member, and an urging member. The outer cylinder member includes a channel, an inner circumferential section provided in an inner circumference of the channel, and an inner circumferential section provided further on the outflow port side than the inner circumferential section. The inner cylinder member includes an advancing/retracting section disposed to be capable of advancing and retracting along the channel and having an outer diameter smaller than an outer diameter of the inner circumferential section, an O-shaped ring disposed in an outer circumference of the advancing/retracting section and configured to fill a gap between the advancing/retracting section and the inner circumferential section when the advancing/retracting section is disposed in the inner circumferential section, and a through-path that pierces through the advancing/retracting section along the channel.

Abstract: An endoscope reprocessor includes an immersion tank, a convex-shaped groove, a lid portion, a liquid supply section, a discharge port as an opening from which the liquid is discharged and which is provided at the liquid supply section, the discharge port being arranged such that a part of the opening is opposed to a side surface of the convex-shaped groove, and a control section that drives the liquid supply section to allow the liquid to be introduced into the immersion tank up to a first water level at which a flat portion of the lid portion is immersed in the liquid, and to allow the liquid to be discharged toward the flat portion and the side surface through the discharge port at the first water level.

Abstract: An endoscope reprocessor includes: a liquid supply nozzle including a lifting conduit configured to feed a liquid in a direction against gravity and a turndown conduit; a liquid ejection port; a treatment tank configured to receive the liquid ejected from the liquid ejection port, the treatment tank allowing an endoscope to be placed inside; a liquid sampling port provided in a connection portion; and a relief cap including a cover configured to cover the liquid sampling port, a fitting portion configured to make the cover be detachably attachable to the connection portion, and an opening/closing portion configured to, if an inner pressure of the liquid supply nozzle exceeds a predetermined value, eject the liquid in a direction with gravity.
