A fluid feeding apparatus includes: a first connection portion configured to be connected to a first container in which fluid is stored; a second connection portion configured to be connected to a second container in which fluid is stored; a first flow path that communicates with the first connection portion; a second flow path that communicates with the second connection portion; a resistance portion configured to generate a difference of conduit resistance to cause one of the first flow path and the second flow path to be higher in the conduit resistance than the other flow path; and a switching portion switching a level relationship of the conduit resistance between the first flow path and the second flow path.

An apparatus is operable to process a medical instrument by passing a detergent and a disinfectant through a plurality of channels defined by the medical instrument. The apparatus includes a detection system, a set of instrument profiles, and a control system. The detection system is configured to collect information regarding the channels of the medical instrument. The control system is configured to pass a detergent and a disinfectant through the channels of the medical instrument based at least in part on a selected instrument profile selected from the set of instrument profiles. The selected instrument profile is selected based at least in part on the information collected by the detection system.

A medical instrument processor includes an enclosure, a liquid distribution system, and a disinfectant concentration measuring subsystem. The enclosure is configured to hold a medical instrument. The liquid distribution system is configured to deliver a disinfection solution to a medical instrument within the enclosure. The liquid distribution system has a liquid outlet. The disinfectant concentration measuring subsystem includes a first mixing chamber in fluid communication with the liquid outlet, a pump that is configured to simultaneously pump the disinfection solution and the reagent solution into the first mixing chamber, and a concentration analysis assembly that is operable to determine a concentration of disinfectant in a sample solution that is output from the first mixing chamber. The reservoir is in fluid communication with the first mixing chamber.

The invention includes devices, arrangements and methods for treating an endoscope after use to prevent adhesion of bioburden on internal walls of a lumen of the endoscope. After treatment, the device is stored in the treated condition until cleaning. The device is configured to selectively deliver cleaning solution to the endoscope. The device can be a circulating embodiment having a pump. A filter can be provided to filter debris during circulation. The device can be a non-circulating embodiment having a hydrophobic filter for release of air. Fittings are provided on the device components to selectively attach the device to endoscopes.

An adapter device for use in a reprocessing device for reprocessing surgical instruments. The adapter device including: at least one first fluid attachment, on an inlet side for connection to a coupling device of the reprocessing device; at least one second fluid attachment, on an outlet side for connection to the surgical instrument, the at least one second fluid attachment being adapted geometrically to an attachment of the surgical instrument; and an adapter identification feature that is detectable by the reprocessing device. Also provided is a reprocessing system having a reprocessing device for reprocessing surgical instruments and having the adapter device. The reprocessing device including: the coupling device for connecting to the adapter device; and a detection device which detects, with the adapter device connected to the reprocessing device, the adapter identification feature of the adapter device.

An endoscope reprocessor includes: a connector to which an endoscope is connected; a fluid supplying section that supplies fluid to the connector; an electromagnet arranged at the connector and including a magnetic material and a coil wound around the magnetic material; a current supplying section; a magnetic force switching portion configured to switch a strength of a magnetic force to at least one of a first strength and a second strength weaker than the first strength; and a control section configured to switch the strength of the magnetic force by controlling the magnetic force switching portion while driving the fluid supplying section.

A medical device reprocessor is operable to perform a method of cleaning an internal channel of a medical device. The method entails activating a pump assembly to deliver a detergent to the internal channel for a first predetermined duration, activating the pump assembly to deliver water to the internal channel to rinse out the detergent for a second predetermined duration, and activating the pump assembly to deliver pressurized air to the internal channel to purge out the water or detergent contained within the internal channel for a third predetermined duration. Subsequently, the method involves activating the pump assembly to deliver a predetermined volume of disinfectant to the internal channel, and activating the pump assembly to deliver pressurized air to purge out the disinfectant into a chamber. The method repeats filling the internal channel with detergent, water and disinfectant and the subsequent purging of the internal channel with pressurized air.

An endoscope cleaning/disinfecting apparatus includes an endoscope connection section, a liquid supply conduit, a gas feeding conduit, a first gas feeding section, a first exhaust section, and a control section that performs a step of filling the gas feeding conduit with a cleaning liquid, a step of opening the first exhaust section, a step of allowing a gas to flow from the first gas feeding section to the endoscope connection section and feeding a two-phase gas-liquid fluid with which the gas feeding conduit is filled into the conduit of the endoscope and a step of closing the first exhaust section a predetermined time after allowing the gas to flow.

An endoscope includes: a long member that is connected to a direction changing portion provided in an insertion portion and enables the direction changing portion to move; a sliding member that includes a first contact portion that is brought into contact with an inner surface of a guide tube that allows insertion of the long member and a second contact portion that is brought into contact with the inner surface of the guide tube; a flow path that includes an opening portion formed in a direction that intersects a longitudinal axis of the sliding member such that a fluid flows into a clearance between the guide tube and the sliding member; and an operation member that causes the sliding member to move forward and backward relative to the guide tube.
