1. A cleaning device for cleaning a medical instrument, the medical instrument having a distal end portion defining an instrument lumen and proximal and distal openings in fluid communication with the instrument lumen, the cleaning device comprising:

  • a flushing chamber having opposite proximal and distal ends, and a length extending between the proximal and distal ends, wherein the flushing chamber comprises an upper luminal portion and a lower luminal portion;

    an inlet port in fluid communication with the flushing chamber and configured for fluid connection to a source of fluid; and

    an outlet port in fluid communication with the flushing chamber such that fluid directed into the flushing chamber through the inlet port can be discharged from the flushing chamber through the outlet port,wherein the flushing chamber is selectively openable along its length to an open position, in which the upper and lower luminal portions are separated from one another so that the distal end portion of the medical instrument is insertable into the flushing chamber, and selectively closable along its length to a closed position, in which the upper and lower luminal portions enclose and fluidly seal around the distal end portion of the medical instrument,wherein each of the upper and lower luminal portions is elastic,wherein each of the upper and lower luminal portions comprises a proximal section proximal of the inlet port along the length of the flushing chamber, a distal section distal of the outlet port along the length of the flushing chamber, and a central section between the inlet port and the outlet port along the length of the flushing chamber, andwherein when the flushing chamber is in the closed position, the proximal sections of the upper and lower luminal portions are configured to form a proximal fluid seal about the medical instrument proximal of the proximal opening, the distal sections of the upper and lower luminal portions are configured to form a distal fluid seal distal of the distal opening, and the central sections of the upper and lower luminal portions are configured to form a central fluid seal about the distal end portion of the medical instrument between the proximal and distal openings.
