Abstract

A cleaning device includes a flushing chamber having opposite proximal and distal ends, and a length extending between the proximal and distal ends. An inlet port of the cleaning device is in fluid communication with the flushing chamber and configured for fluid connection to a source of fluid. The flushing chamber is selectively openable along its length to an open position, in which 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 distal end portion of the medical instrument is enclosed and fluidly sealed within the flushing chamber.

Claims

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 lower half and an upper half pivotably connected to one another by a hinge, the upper and lower halves being selectively pivotable about the hinge between an open position and a closed position;

each of the upper and lower halves including a luminal portion having a luminal portion axis, the luminal portions of the upper and lower halves in the open position being spaced apart from one another to receive the distal end portion of the medical instrument therebetween and in the closed position defining a flushing chamber having opposite proximal and distal ends and a length extending along the luminal portion axis between the proximal and distal ends, the luminal portions being shaped and arranged to enclose and fluidly seal the distal end portion of the medical instrument within the flushing chamber in the closed position;

an inlet port in fluid communication with the flushing chamber and configured to be in fluid communication with the instrument lumen, and configured for fluid connection to a source of fluid,

wherein each of the luminal portions of the upper and lower halves is elastic and configured when in the closed position to seal around the outer diameter of the received distal end portion of the medical instrument,

wherein the luminal portion of the upper half defines a groove extending along the luminal portion axis through the proximal and distal ends of the flushing chamber, the groove configured to receive the distal end portion of the medical instrument therein.

2. The cleaning device of claim 1, further comprising a spring secured to the upper and lower halves and biasing the flushing chamber in the closed position.

3. The cleaning device of claim 2, wherein the spring is configured to hold the upper and lower halves in the closed position when the distal end portion of the medical instrument is operatively received in the flushing chamber and fluid operative to flush the instrument lumen of the medical instrument is introduced in the flushing chamber.

4. The cleaning device of claim 1, wherein the inlet port is connected to the flushing chamber such that the proximal opening in the distal end portion of the medical instrument is adjacent the inlet port when the distal end portion is enclosed and fluidly sealed in the flushing chamber.

5. The cleaning device of claim 4, further comprising an outlet port in fluid communication with the flushing chamber.

6. The cleaning device of claim 5, the outlet port is connected to the flushing chamber such that the distal opening in the distal end portion of the medical instrument is adjacent the outlet port when the distal end portion is enclosed and fluidly sealed in the flushing chamber.

7. The cleaning device of claim 1, wherein the flushing chamber includes a seal at the proximal end of the flushing chamber for sealing about an outer diameter of the distal end portion of the medical instrument.

8. The cleaning device of claim 7, wherein the distal end of the flushing chamber is open.

9. The cleaning device of claim 1, in combination with the medical instrument having a distal end portion defining an instrument lumen and proximal and distal openings in fluid communication with the instrument lumen, wherein the medical instrument comprises a catheter adapted for intraluminal introduction.

10. The cleaning device of claim 1, wherein each of the handle portions defines a spring seat.

11. The cleaning device of claim 10, wherein the spring seats are spaced apart from the hinge and the luminal portions of the upper and lower halves.

12. The cleaning device of claim 1, wherein the handle portions extend away from the hinge along a handle axis oriented generally perpendicular to the luminal portion axis.
