A medical valve may comprise a valve stem and an operation portion. The operation portion may include a stationary portion, a movable portion which is movable relative to the stationary portion and fixed relative to the valve stem, a seal disposed between the stationary portion and the movable portion, and a biasing member. Movement of the movable portion in a first direction may cause deformation of the biasing member, such that a restorative force of the biasing member urges movement of the movable portion in a second direction opposite the first direction. A frictional force between the seal and one of the stationary portion and the movable portion resists the movement of the movable portion in the second direction.

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.

A liquid feeding conduit includes: a tube body of a cleaning tube through which a fluid passes; an endoscope-side connector provided at an end of the tube body, the endoscope-side connector being connected to a conduit cap of an endoscope conduit; a valve element provided in the endoscope-side connector, the valve element being configured to move toward a side of the conduit cap by a supply pressure of the fluid to thereby watertightly connect the endoscope-side connector and the conduit cap; a spring configured to bias the valve element toward an opposite side of the conduit cap; and a buffer unit configured to delay the movement of the valve element toward the side of the conduit cap.

A dental mirror cleaner that utilizes a spray of high pressure water and air at an angle across the reflective face of a dental mirror while in a patient's mouth to clean debris, blood and condensation from the mirror. It redirects the flow of the water and or air away from the centerline or linear axis of the mirror handle and sprays it offset from this centerline in a hemispherical pattern at an approximate 35 to 45 degree angle across the mirrored face.

A fluid distributor for use with a reprocessing device for reprocessing a surgical instrument having a plurality of channels, including: a routing body having a plurality of connections corresponding to the channels; and a switching body movably disposed in the routing body, the switching body having an interior supply line connected to a fluid reservoir for selectively providing a fluid to one or more of the connections. The switching body can be configured such that, in a first position of the switching body relative to the routing body, the connections of the routing body are each in fluid communication with the supply line of the switching body and in at least a second position of the switching body relative to the fluid routing body less than all of the connections of the routing body are in fluid communication with the supply line of the switching body.

A method for reconditioning an endoscope in a reconditioning apparatus, the method including: connecting an interior of the endoscope to a leakage tester of the reconditioning apparatus; supplying the interior with a fluid at a predefined pressure; carrying out a reconditioning process using a rinsing liquid; monitoring the pressure in the interior of the endoscope during the reconditioning process; and identifying the endoscope as defective if a profile of the pressure deviates from a predefined pressure profile; wherein the predefined pressure profile is determined according to process parameters of the reconditioning process.

A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

A fluid distributor for a reprocessing device for reprocessing surgical instruments. The fluid distributor including: a first fluid routing body having a first fluid hole, the first hole having a first inlet and a first outlet, and a second fluid routing body that has at least two second fluid holes, each of the at least two second fluid holes having a second inlet and a second outlet; wherein the first fluid routing body and the second fluid routing body are rotatable relative to each other about an axis of rotation such that the first fluid hole communicates fluidically in sequence with each of the at least two second fluid holes.

An endoscope cleansing accessory is described for use with an automatic endoscope reprocessing (AER) apparatus which utilizes the motive force provided by a flowing cleansing fluid already within the AER to actuate an actuator wheel of the endoscope during the cleansing process. The movement or actuation of the actuator wheel during cleansing in turn imparts a back and forth motion to an elevator platform or forceps raiser within the endoscope to loosen tissue and other particles that are then flushed out by the flowing cleansing fluid.

An apparatus and method for reprocessing a medical device includes a decontamination basin, a first flush conduit, a second flush conduit, and a manifold. The first and second flush conduits have respective first and second coupling ports configured to fluidly connect to the medical device positioned within the decontamination basin. The manifold is fluidly connected to the first and second flush conduits and configured to distribute the fluid received therein accordingly. The apparatus also includes a first valve, a second valve, and a primary pump configured to discharge the fluid into the manifold at a predetermined supply flow rate. The first and second valve are positioned respectively in the first and second flush conduits for balancing the respective flow rates discharged therefrom at a first predetermined conduit flow rate and a second predetermined conduit flow rate.
