Abstract
A cleaning device for a medical instrument including a flushing chamber, the flushing chamber having a lumen sized and configured to accept a distal end portion of the medical instrument during a cleaning process. The flushing chamber has an inlet port and an outlet port. Proximal and distal sealing members of the flushing chamber seal about the medical instrument when the instrument is inserted into the lumen of the flushing chamber.
Claims22
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, a flushing lumen extending between the proximal and distal ends, and distal and proximal ports in fluid communication with the flushing lumen, wherein the flushing lumen is configured to accept the distal end portion of the medical instrument, through the proximal end of the flushing chamber, such that the proximal opening of the medical instrument is generally adjacent the proximal port and the distal opening of the medical instrument is generally adjacent the distal port;
- a proximal sealing member coupled to the flushing chamber at a location proximal of the proximal port, the first sealing member configured to fluidly seal about the medical instrument when the medical instrument is inserted into the flushing chamber for directing fluid flow between the proximal port and the proximal opening of the medical instrument and inhibiting fluid flow proximal of the proximal sealing member in the flushing lumen;
- and
- a distal sealing member coupled to the flushing chamber at a location distal of the proximal port and proximal of the distal port, the distal sealing member configured to fluidly seal about the medical instrument when the medical instrument is inserted into the flushing chamber for directing fluid flow between the distal port and said distal opening of the medical instrument, and inhibiting fluid flow distal of the distal sealing member in the flushing lumen.
The cleaning device of claim 5, wherein the first distal port has a first stop valve having an open position and a closed position and the second distal port has a second stop valve having an open position and a closed position.
A method of cleaning a medical instrument having a distal end portion defining an instrument lumen, and proximal and distal openings in fluid communication with the instrument lumen, the method comprising:
- providing a cleaning device including
- a flushing chamber having opposite proximal and distal ends, a flushing lumen extending between the proximal and distal ends, and distal and proximal ports in fluid communication with the flushing Lumen,
- a proximal sealing member coupled to the flushing chamber at a location proximal of the proximal port, and
- a distal sealing member coupled to the flushing chamber at a location distal of the proximal port and proximal of the distal port;
- inserting the medical instrument through the proximal end of the flushing chamber and into the flushing lumen such that the proximal sealing member seals about the medical instrument at a location proximal of the proximal opening of the medical instrument, and the distal sealing member seals about the medical instrument at a location intermediate the proximal and distal sealing members;
- and
- introducing fluid into the proximal port of the flushing chamber to create a pressurized flow of fluid through the proximal port of the flushing chamber, into the proximal opening in the medical instrument, through the instrument lumen of the medical instrument, out the distal opening in the medical instrument and then out through the distal port of the flushing chamber, wherein residual matter from previous usage of the medical instrument is ejected with the fluid flow out through the distal port of the flushing chamber.
A cleaning device for cleaning a medical instrument, the cleaning device comprising:
- a flushing chamber having opposite proximal and distal ends, a flushing lumen extending between the proximal and distal ends, and distal and proximal ports in fluid communication with the flushing lumen;
- a proximal sealing member coupled to the flushing chamber at a location proximal of the proximal port;
- and
- a distal sealing member coupled to the flushing chamber at a location distal of the proximal port and proximal of the distal port.
