One embodiment of the present invention is a disposable, single use, enclosed device with two internal nozzles. Another embodiment of the present invention is a reusable enclosed device with two internal nozzles. The nozzles are placed in such a way that they enter into the two spaces around the elevator. The tip of the endoscope rests in a tray and the top of the device is closed creating a closed, water proof chamber. The nozzles are in turn connected to a pump and/or apparatus which magnetically charge the water and pump the magnetic water with a high physical force as a forced jet. Water can be changed to a disinfectant solution or yet another solution, or the water, disinfectant solution and/or other solution can be alternated. The force of the water and the magnetic charge clear debris and fluid which may be otherwise hard to reach. Further, the same system can be used with an antiseptic solution to clean the scope after the magnetic hydrostatic cleaning. This cleaning process using the magnetic water can be done right after the procedure or even before a procedure whereby every scope is cleaned again just before each use. Advantages of the device include: magnetically charged water prevents bacteria from sticking to the surface; high pressure water jet removes debris and body fluids from deep crevices which are otherwise hard to clean; and the ability to use different fluids like disinfectant fluids can reduce or eliminate chances of transmission of infection.

Various embodiments of the present invention provide devices, systems and methods for cleaning medical tools with an elevator mechanism, including but not limited to duodenoscopes, linear echoendoscopes, side viewing endoscopes, and medical tools that have difficult-to-reach areas, spaces or crevices and require manual cleaning. In accordance with the present invention, an “elevator” mechanism refers to a movable mechanism that changes the angle of an accessory exiting an accessory channel of a medical tool. For example, the elevator mechanism of duodenoscopes allows duodenoscopes to access the ducts to treat problems with fluid drainage. One step of the manual cleaning is to brush the elevator area. However, the moving parts of the elevator mechanism contain microscopic crevices that may not be reached with a brush. Residual body fluids and organic debris may remain in these crevices after cleaning and disinfection. If these fluids contain microbial contamination, subsequent patients may be exposed to serious infections.

Some types of endoscopes, such as side viewing duodenoscopes and linear echoendoscopes, have an elevator at their tips. Because the narrow crevices and spaces around the elevator are difficult to reach, these medical tools cannot be reliably cleaned. Indeed, the debris and body fluids retained on duodenoscopes have been reported to cause transmission of multi-drug resistant bacteria. To solve the problem, various embodiments of the present invention provide a cleaning device. In some embodiments, the cleaning device is disposable and single use. In other embodiments, the cleaning device is reusable. In various embodiments, the cleaning device has two nozzles arranged in such a way that they can be positioned near and/or inserted into the two spaces beside the elevator. The two nozzles are also connected via tubing to a pump, one or more liquid containers for water and/or disinfectant solutions, and a magnetic water generator that magnetically charges water (and/or disinfectant solutions). The water (and/or disinfectant solutions) that has been magnetically charged is then referred to as “magnetic water” (and/or “magnetic disinfectant solutions”). After the endoscope tip is placed in the tray, the top cover is closed to create a water tight seal. The pump pumps water (and/or disinfectant solutions) out of the two nozzles as high pressure water jets into the narrow crevices and spaces around the elevator, and as a result, any debris and body fluids retained there are cleaned by the water jets' force and magnetic charge. Various cleaning devices and systems described herein can be used for cleaning side viewing duodenoscopes and linear echoendoscopes manufactured by OLYMPUS, PENTAX, FUJIFILM, FUJINON, HOYA, KARL STORZ GmbH & Co., US ENDOSCOPY, BOSTON SCIENTIFIC, MEDTRONIC, and ENDOCHOICE.
