Abstract

An apparatus and method for reprocessing a medical device includes a decontamination basin, a first flush conduit, a second flush conduit, and a manifold. The first and second flush conduits have respective first and second coupling ports configured to fluidly connect to the medical device positioned within the decontamination basin. The manifold is fluidly connected to the first and second flush conduits and configured to distribute the fluid received therein accordingly. The apparatus also includes a first valve, a second valve, and a primary pump configured to discharge the fluid into the manifold at a predetermined supply flow rate. The first and second valve are positioned respectively in the first and second flush conduits for balancing the respective flow rates discharged therefrom at a first predetermined conduit flow rate and a second predetermined conduit flow rate.

Claims (24)

1. A method of reprocessing a medical device with a disinfectant, the method comprising:

(a) pumping the disinfectant from a disinfectant storage reservoir toward a decontamination basin with a disinfectant pump, wherein the decontamination basin contains the medical device;

(b) directing the disinfectant along at least one of a circulation phase or a collection phase with a primary pump fluidly connected to the decontamination basin and configured to receive the disinfectant therefrom;

(c) directing the disinfectant from the primary pump and toward the decontamination basin in the circulation phase; and

(d) transitioning from the circulation phase to the collection phase to direct the disinfectant from the primary pump and toward the disinfectant storage reservoir.

2. The method of claim 1 , further comprising:

(a) directing the disinfectant from the disinfectant pump toward a neutralization tank fluidly connected between the decontamination basin and the disinfectant pump; and

(b) neutralizing the disinfectant in the neutralization tank.

3. The method of claim 1 , further comprising:

(a) receiving a fluid from a fluid supply within an introduction valve in a supply state thereby directing the fluid from the introduction valve toward the decontamination basin along an introduction conduit; and

(b) inhibiting the fluid from the fluid supply from flowing along a recirculation conduit via the introduction valve in the supply state.

4. The method of claim 3 , further comprising:

(a) transitioning the introduction valve from the supply state to a recirculation state to thereby fluidly connect the introduction conduit to the recirculation conduit and inhibit the fluid from the fluid supply from flowing into the introduction conduit; and

(b) directing the disinfectant from the primary pump along the recirculation conduit toward the introduction conduit and the decontamination basin.

5. The method of claim 1 , further comprising disinfecting the medical device using the disinfectant disposed within the decontamination basin.

6. The method of claim 1 , further comprising diluting the disinfectant from a first concentration to a second concentration.

7. The method of claim 6 , wherein diluting the disinfectant further comprises mixing the first concentration of the disinfectant mixed with water to produce the second concentration of the disinfectant.

8. The method of claim 1 , wherein pumping the disinfectant further comprises pumping the disinfectant directly into the decontamination basin from the disinfectant storage reservoir.

9. The method of claim 1 , further comprising measuring a temperature of fluid in the decontamination basin using a temperature sensor.

10. The method of claim 1 , further comprising heating the disinfectant using a disinfectant heater.

11. The method of claim 1 , further comprising heating the disinfectant using a disinfectant heater while the disinfectant flows from disinfectant storage reservoir toward the disinfectant pump.

12. The method of claim 1 , further comprising communicating with a control system using a fluid level sensor, at least one of a minimum fluid level of the disinfectant disposed in the disinfectant storage reservoir or a maximum fluid level of the disinfectant disposed in the disinfectant storage reservoir.

13. The method of claim 1 , further comprising measuring an excess of fluid collected within a drain sump using a drain sump overflow sensor.

14. The method of claim 1 , further comprising fluidly connecting the primary pump with an introduction valve using a self-disinfection pathway such that the introduction valve receives fluid from the self-disinfection pathway to self-disinfect an inlet path fluidly connecting the introduction valve to the decontamination basin, wherein the self-disinfection pathway is fluidly connected downstream of the primary pump, wherein the self-disinfection pathway and a manifold are respectively in parallel fluid communication with the decontamination basin.
