The invention is concerned with a device and a method for cleaning and disinfecting medical instruments, in particular instruments of minimal invasive surgery (MIS). Instead of the rigid connection of cleaning tubings to instrument connections and exits which has been used up to now and which have the disadvantage that certain contaminated regions remain inaccessible for a secure cleaning, there is suggested a docking of injector nozzles in defined chronological intervals, the injector nozzles being fixed in a centric position to the openings of the instrument connections. At the same time various types of injector nozzles are applied for adaptation to various instrument connections and openings. By measuring the rinsing fluid quantity flowing to the instrument connections and the total discharging rinsing fluid quantity, the quality of preparation may be evaluated and documented.

[ I claim:] [1.] An apparatus for rinsing a channel of a medical instrument with a fluid supplied by a fluid supply under a pressure, the medical instrument having a channel connector communicating with the channel, comprising:a fluid injector for selectively forming a sealed connection with the channel connector for transferring fluid from the fluid supply thereto, said fluid injector comprising:a hollow tubular housing having a central longitudinal axis, a proximal end, and a distal end sized and configured to selectively connect to the channel connector of the medical instrument;an opening for receiving fluid supplied by the fluid supply; anda plunger movably disposed at least partially within said tubular housing, said plunger having a front portion, a rear portion, a fluid passage running axially therein, and being movable along the central longitudinal axis, wherein said front portion of said plunger is sized and configured to form a sealable connection with the channel connector of the medical instrument, such that when said tubular housing and said front portion of said plunger are axially aligned with the channel connector and fluid from the fluid supply is delivered into the housing, the pressure exerted by the fluid on said plunger is sufficient to cause said plunger to move along said central longitudinal axis of said housing into a sealed connection with the channel connector for delivery of the fluid through said fluid passage thereto.
