A fluid handling system for a surgical procedure includes a console and a tubing set. The console exhibits a peristaltic pump, a pinch valve, one above the other. Two recessed seats are located to the left and right sides of the pump and valve. The tubing set includes an irrigation tube and an aspiration tube each coupled to a pair of magnetic disks disposable in respective ones of the recessed seats. Upon such disposition, the irrigation tube is disposable in operative engagement with the peristaltic pump and the aspiration tube is insertable into a slot of the pinch valve.

Various embodiments provide a sterilisation apparatus for sterilising a channel of a surgical scoping device. The apparatus includes: a gas supply having a conduit to deliver an ionisable gas to the channel of the surgical scoping device; and, a sterilisation instrument, separate from the gas supply and the conduit, configured to be inserted through the channel of a surgical scoping device. The sterilisation instrument includes an elongate probe. The elongate probe includes: a transmission line for conveying radiofrequency (RF) electromagnetic (EM) energy and/or microwave EM energy; and, a probe tip connected at the distal end of the transmission line for receiving the RF and/or microwave EM energy, the probe tip comprising an electrode assembly configured to produce an electric field from the received RF and/or microwave frequency EM energy to generate a plasma of the ionisable gas delivered to the channel from the gas supply.

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 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.

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.

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.

A method for reprocessing a medical device uses a medical device processor with an enclosure for holding the medical device. The enclosure also has a reservoir containing a disinfectant, a water source, and a mixing chamber that retains the medical device. The method delivers disinfectant from the reservoir to an internal channel of the medical device, and further delivers water from the water source to the mixing chamber. A flow sensor is operable to monitor the disinfectant delivered to the internal channels of the medical device.

A process to clean medical devices, such as endoscopes, with a turbulent cleaning solution is described. The process includes providing cleaning solution in a first delivery system and providing a gas in a second delivery system, wherein the first and second delivery system are connected to a third delivery system that allows the cleaning solution and gas to combine to provide a turbulent cleaning solution that can be passed through a lumen of a medical device. The process is generally accomplished by use of a peristaltic pump with two heads; one head for each of the delivery system. The resultant turbulent cleaning solution provides enough force to dislodge most body fluids, debris, bacteria and/or virus(es) from the surface of the medical device without the requirement for physical scrubbing or brushing of the surface.

In at least some aspects, an instrument port for introducing an instrument into a surgical site comprises: a port body having: an instrument channel extending through the port body; and a plurality of fluid flush channels each separate from one another and the instrument channel, each extending along a major portion of the port body and in fluid communication with the instrument channel; and a bulb comprising a bulb channel extending through the bulb, the bulb channel aligned with the instrument channel, wherein the bulb channel and instrument channel are configured to receive the instrument.

A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to fluid (e.g., air and water) channels of an endoscope. Many embodiments described herein may include a cleaning valve (or valve) that is appropriate for single-use and therefore may be disposable. Accordingly, the valve may be made from a limited number of parts and materials, e.g., to limit its cost and/or manufacturing complexity. For example, multiple seals may be integrally formed with a valve stem. In another example, the valve may have an interface member, which may combine and simplify the functionality of a number of components, such as by connecting the valve stem to a valve well, sealing an opening to a lumen in the valve stem, and/or biasing the valve stem into a position relative to the valve well.
