Cleaning device for cleaning medical instrument
First Claim
1. A cleaning device for cleaning a medical instrument having a distal end portion defining an instrument lumen, the cleaning device comprising:
- a device body comprising first and second body portions having respective inner faces, the first and second body portions being movable relative to one another between a closed position, in which the inner faces are generally abutting and in opposing relationship with respect to one another, and an open position, in which the inner faces are spaced apart such that the medical instrument is receivable between the inner faces, the respective inner faces of the first and second body portions defining an internal flushing chamber of the device body when the first and second body portions are in the closed position;
an inlet port in fluid communication with the flushing chamber and configured to fluidly connect a source of fluid to the flushing chamber;
first and second sealing members secured to the inner faces of the respective first and second body portions, the first and second sealing members including respective first and second chamber sealing portions having respective first and second sealing surfaces adapted to engage one another to form a seal interface therebetween when the first and second body portions are in the closed position, wherein the first chamber sealing portion extends into the flushing chamber and has a first pressure surface opposite the first sealing surface and exposed to fluid pressure within the flushing chamber to enhance tightness of the seal interface when a positive fluid pressure is present in the flushing chamber.

Abstract
A cleaning device for cleaning a medical instrument. First and second body portions in a closed position define a flushing chamber. The medical instrument extends through the flushing chamber. First and second sealing members secured to the first and second body portions engage one another to seal the flushing chamber and engage the medical instrument to form a seal thereabout. Portions of at least the first sealing member are disposed within the flushing chamber. Positive pressure in the flushing chamber urges the first sealing member toward the second and toward the medical instrument to enhance the tightness of the flushing chamber seal.

15. A cleaning device for cleaning a medical instrument having a distal end portion defining an instrument lumen, the cleaning device comprising:
-
a device body comprising first and second body portions having respective inner faces, the first and second body portions being movable relative to one another between a closed position, in which the inner faces are generally abutting and in opposing relationship with respect to one another, and an open position, in which the inner faces are spaced apart such that the medical instrument is receivable between the inner faces, the respective inner faces of the first and second body portions defining respective first and second flushing cavities together defining an internal flushing chamber of the device body when the first and second body portions are in the closed position; an inlet port in fluid communication with the flushing chamber and configured to fluidly connect a source of fluid to the flushing chamber; first and second sealing members secured to the inner faces of the respective first and second body portions, the first and second sealing members including respective first and second chamber sealing portions having respective first and second sealing surfaces adapted to engage one another to form a seal interface therebetween when the first and second body portions are in the closed position, wherein the first and second chamber sealing portions extend over portions of the respective first and second flushing cavities such that pressurized fluid in the flushing chamber imparts forces on the first and second chamber sealing portions that urge the first and second sealing surfaces together. - View Dependent Claims (16, 17, 18, 19, 20)
