Abstract

An apparatus for cleaning an instrument with a cleaning fluid includes a vessel defining a chamber and a port for at least partially filling the chamber with the fluid. The apparatus further includes an ultrasonic transducer for delivering ultrasonic energy to the fluid, and a vacuum pump for depressurizing the chamber. The apparatus further includes a rotatable device removably disposable in the chamber and having a rack defining a cavity for supporting the instrument. The rotatable device also has a fluid delivery member extending toward the cavity and having a fluid channel between an inlet and an outlet. The apparatus further includes a fluid transmission system in fluid communication with the chamber and the fluid channel of the fluid delivery member for circulating the fluid from the chamber through the fluid channel of the fluid delivery member. A method of cleaning an instrument is also provided.

Claims

1. An apparatus for cleaning an instrument with a cleaning fluid, wherein the instrument has a lumen, and said apparatus comprising:

a vessel defining a chamber and a port for at least partially filling said chamber with the cleaning fluid;

an ultrasonic transducer operatively coupled to said vessel for delivering ultrasonic energy to the cleaning fluid in said chamber;

a vacuum pump operatively coupled to said vessel for depressurizing said chamber;

a rotatable device removably disposable in said chamber and defining a longitudinal axis with said rotatable device being rotatable about said longitudinal axis and having a rack defining a cavity for supporting the instrument, said rotatable device further having a projection extending towards said cavity of said rack for jetting the cleaning fluid into the lumen of the instrument with said projection having a length for at least partially extending into the lumen of the instrument and said projection defining an inlet for receiving the cleaning fluid, an outlet for jetting the cleaning fluid into the lumen of the instrument, and a fluid channel extending along said length between said inlet and said outlet; and

a fluid transmission system in fluid communication with said chamber and said fluid channel of said projection for circulating the cleaning fluid from said chamber through said fluid channel of said fluid delivery member.

2. The apparatus as set forth in claim 1 wherein said fluid transmission system has a conduit in fluid communication with said chamber and a pump operatively coupled to said conduit for circulating the cleaning fluid from said chamber through said fluid channel of said projection.

3. The apparatus as set forth in claim 1 wherein said rotatable device further has a base and a wheel coupled to said base with said projection coupled to and extending from said base.

4. The apparatus as set forth in claim 1 further comprising:

a receptacle for holding the cleaning fluid;

a conduit in fluid communication with said receptacle and said port of said vessel for at least partially filling said chamber with the cleaning fluid with said conduit having a valve for controlling flow of the cleaning fluid from said receptacle to said chamber.

5. The apparatus as set forth in claim 1 further comprising an injector operatively coupled to said vessel and in fluid communication with said chamber with said injector operable for injecting water into said chamber or for injecting air into said chamber.

6. The apparatus as set forth in claim 5 wherein said vessel defines a longitudinal axis and said port is one of a plurality of ports defined parallel to said longitudinal axis of said vessel and said injector is one of a plurality of injectors with each of said injectors operatively coupled to said vessel and in fluid communication with a respective one of said ports.

7. The apparatus as set forth in claim 1 further comprising a processor having a non-transitory, computer-readable storage medium with a plurality of executable programs stored thereon with each of said executable programs containing computer-readable instructions for a respective, predetermined cleaning protocol.

8. The apparatus as set forth in claim 1 wherein said ultrasonic transducer is one of a plurality of ultrasonic transducers and said apparatus further comprises a controller in selective communication with each of said plurality of ultrasonic transducers for controlling a power output of each of said plurality of ultrasonic transducers.
