An endoscope connection tube includes a fluid feeding pipeline that has a first end portion connected to a pipe sleeve of an endoscope, and a second end portion connected to a fluid supply source; a seal portion that is provided in the first end portion of the fluid feeding pipeline, includes a close contact surface configured to closely contact the pipe sleeve to surround an opening portion of the pipe sleeve, and is configured to connect an inside of the fluid feeding pipeline and an inside of the opening portion when the close contact surface closely contacts the pipe sleeve; and a detection pipeline that has a first end portion opened in the close contact surface, and is configured to be closed by the pipe sleeve when the close contact surface is in close contact with the pipe sleeve.

Endoscope connection tube and endoscope reprocessor

A cleaning tool for insertion device includes a first fluid supply conduit, a second fluid supply conduit, a first cap component, and a second cap component, wherein a first discharge port and a third discharge port are disposed at positions where a discharging direction of fluid discharged from the first discharge port and a discharging direction of fluid discharged from the third discharge port are parallel or coaxial to each other in a vertical direction of a distal end portion of an insertion device, and a second discharge port and a fourth discharge port are disposed at positions where a discharging direction of fluid discharged from the second discharge port and a discharging direction of fluid discharged from the fourth discharge port are parallel or coaxial to each other in a lateral direction of the distal end portion of the insertion device.

Cleaning tool for insertion device

A cleaning tool for insertion instrument includes: a cleaning cap configured to be attachable to and detachable from a distal end component portion provided on a distal end side of an insertion portion in an endoscope and covered by a tubular cover when the endoscope is used, attachment and detachment of the cleaning cap to and from the distal end component portion being performed in a state where the cover is removed from the distal end component portion; and a cap-side engaging portion provided on the cleaning cap and configured to be engaged with a distal end component portion-side engaging portion provided on an outer peripheral surface, at least a part of which is covered by the cover, of the distal end component portion.

An endoscope reprocessor includes: a housing unit that houses a medicinal solution bottle such that a sealing portion is located on a top surface; a first guide that guides the housing unit such that the housing unit is capable of advancing and retreating between a first point and a second point; a movable unit that moves in cooperation with advancing of the housing unit; an unsealing member provided in the movable unit and arranged at a position higher than the sealing portion of the medicinal solution bottle housed in the housing unit at the first point, the unsealing member having a shape protruding toward the top surface at a predetermined length to pierce the sealing portion when the medicinal solution bottle reaches the second point by descending as the movable unit advances; and a second guide that guides an advancing direction of the movable unit.

Endoscope reprocessor

An endoscope reprocessor includes: a concentration measurement chamber; a liquid concentrate supply unit; a diluent supply unit; a holding unit configured to hold a concentration sensor; a memory; and a processor configured to produce information on a temporary standard curve based on a first point at which a first concentration is associated with a sensor output value at measurement of concentration of liquid concentrate and a second point at which a second concentration is associated with a sensor output value at measurement of concentration of a practical use solution after dilution, calculate a deviation degree between a standard curve and the temporary standard curve, and determine whether the temporary standard curve is valid from the deviation degree.

An endoscope reprocessing tool includes: a connection portion configured to be connected with a fluid outlet provided on a bottom face of a reprocessing basin of an endoscope reprocessor; a direction changing portion configured to change a flow direction of fluid discharged from the fluid outlet from a direction against a gravity direction to a direction crossing the gravity direction; a discharge portion configured to discharge the fluid direction-changed by the direction changing portion in the direction crossing the gravity direction; and a positioning portion configured to position a distal end portion of an endoscope so that the discharge portion and a recess portion provided on the distal end portion face each other.

Endoscope reprocessing tool

A linear member delivery device for the endoscope includes: a nozzle including an inlet, an outlet, and an insertion path; a fitting portion fitted to an endoscope; a holding portion configured to hold a linear member; and a switching portion configured to connect the fitting portion and the nozzle such that a crossing angle of an opening of the endoscope and a center axis of the nozzle can be switched to a plurality of angles in a state that the fitting portion is fitted to the endoscope.

Linear member delivery device for endoscope

A separator unit is a cleaning auxiliary tool to be inserted into an air/water feeding cylinder. The separator unit includes a partition plate for partitioning an air feeding conduit side and a water feeding conduit side, and two elastic members in an air/water feeding cylinder. The two elastic members are arranged at an outer circumferential side of the partition plate. When an internal pressure on the air feeding conduit side corresponds to an internal pressure on the water feeding conduit side, the elastic members are spaced apart from an inner wall of the air/water feeding cylinder by a predetermined distance, and when one of the internal pressures on the air feeding conduit and the water feeding conduit becomes higher than the other, one of the elastic members is deformed by receiving the higher internal pressure and comes in close contact with the inner wall of the air/water feeding cylinder.

Cleaning auxiliary tool

A linear member transfer apparatus includes: a linear member housing portion having a bottomed cylindrical shape and including: a bottom portion; an opening; a side wall; a restriction portion that is a diaphragm disposed on a position at a predetermined distance from the bottom portion and that has an inner diameter smaller than an inner diameter of the bottom portion; a first chamber configured to house a linear member in a wound state; and a second chamber configured to house the linear member in an extended state; a transfer portion configured to transfer the linear member; and a guide.

Linear member transfer apparatus

An endoscope cleaning tube according to the invention includes a housing portion; a movable portion adapted to divide an inner part of the housing portion into a side of the fluid introduction port and a side of the fluid lead-out port and placed between a first position and a second position in the housing portion, the second position being located closer to the side of the fluid lead-out port than the first position; a pressure-receiving portion which, being equipped with a pressure-receiving surface placed at a position facing the fluid introduction port and adapted to receive pressure of the fluid, is adapted to pivot according to fluid pressure on the pressure-receiving surface; and a linking portion adapted to connect the movable portion and the pressure-receiving portion with each other and move the movable portion from the second position to the first position when the pressure-receiving portion receives the fluid pressure.

Endoscope cleaning tube

A guide tube having a tube; a ciliary portion including many cilia inclined in a longitudinal direction of the tube, provided in an outer peripheral portion of the tube; and a vibration portion provided on the tube for vibrating the ciliary portion so as to move the tube in the longitudinal direction.
