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.

A reusable apparatus, such as a medical instrument or tool, is decontaminated by applying pressure waves with direct contact of the pressure wave applicator to the reusable apparatus in an open bath in a sufficient dosage to remove contamination but without adversely affecting the ability to reuse the apparatus.

An Albarran deflector can be cleaned or reconditioned particularly thoroughly. This is achieved in that at least one flushing port is arranged on a drive body of the Albarran deflector. During cleaning or reconditioning, a flushing line can be connected to this flushing port. This defined access to the interior of the drive body or gear space allows targeted introduction of the flushing fluid.

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.

A method is provided for reprocessing an internal channel of a medical device with a reprocessing system having a valve, a fluid line fluidly coupled with the valve, and at least one sensor coupled with the fluid line. The method includes performing an actuation of the valve to direct liquid through the fluid line and into the internal channel, and detecting with the at least one sensor a predetermined condition within the fluid line while the liquid is being directed into the internal channel. In response to detecting the predetermined condition, a time duration measured from the actuation of the valve is recorded. The method further includes purging the liquid from the internal channel, and directing liquid through the fluid line and into the internal channel for the time duration.

An instrument reprocessor for cleaning, disinfecting, and/or sterilizing a medical instrument is disclosed. To reprocess instruments having one or more channels defined therein, the reprocessor can include one or more flow control systems configured to control a flow of fluid through each channel. In various embodiments, a flow control system can include a differential pressure sensor and a proportional valve for controlling the fluid flow in a channel. The reprocessor can also include, one, a fluid circulation pump which can be configured to supply the flow control systems with fluid and, two, a system for controlling the pressure of the fluid supplied to the flow control systems. The reprocessor can also include a system for supplying a metered amount of fluid to the fluid circulation system. The system can include a reservoir having a fluid height sensor to monitor the amount of fluid therein and a pump configured to supply the reservoir with fluid.

A coupling for coupling one or more hoses to a cleaning machine including at least one connector for the connecting of a hose to be cleaned with a pillar and at least one pillar for the connection of the connector with a cleaning machine, wherein the pillar includes a longitudinal hollow body with at least two open ends including; a longitudinal guidance part, situated towards a first end; and a second end opposite to the first end in longitudinal direction; wherein the guidance part is provided with a thickening for the fixing of the connector to the guidance part, which thickening includes a first slope facing the first end, which slope has an angle with the guidance part between 5 and 45 degrees; and includes a second slope facing the second end, which slope has an angle with the guidance part between 30 and 60 degrees.

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.

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.
