Abstract
A method for reprocessing a medical device uses a medical device processor with an enclosure for holding the medical device. The enclosure also has a reservoir containing a disinfectant, a water source, and a mixing chamber that retains the medical device. The method delivers disinfectant from the reservoir to an internal channel of the medical device, and further delivers water from the water source to the mixing chamber. A flow sensor is operable to monitor the disinfectant delivered to the internal channels of the medical device.
Claims20
A method for reprocessing at least one medical device contained within an enclosure, the enclosure comprising a liquid distribution system in fluid communication with a mixing chamber, the method comprising:
- (a) activating a pump to deliver a disinfectant or detergent to an internal channel of the at least one medical device;
- (b) deactivating the pump and closing a valve in fluid communication with the internal channel once a time threshold is achieved;
- (c) releasing the disinfectant or detergent from the internal channel and into the mixing chamber when the internal channel has held the disinfectant or detergent for a minimum dwell time;
- (d) activating a pump to deliver water to the mixing chamber;
- and
- (e) circulating the mixture of the disinfectant or detergent and the water in the mixing chamber for a predetermined time thereby exposing an outer surface of the at least one medical device to the mixture.
A method for reprocessing at least one medical device contained within an enclosure, the at least one medical device including an internal channel having a volume, the enclosure comprising a liquid distribution system in fluid communication with a mixing chamber, the method comprising:
- (a) activating a pump to deliver a disinfectant or detergent to an internal channel of the at least one medical device;
- (b) deactivating the pump once an amount of the disinfectant or detergent delivered to the internal channel substantially equals the volume of the internal channel;
- (c) closing a valve in fluid communication with the internal channel;
- (d) releasing the disinfectant or detergent from the internal channel and into the mixing chamber when the internal channel has held the disinfectant or detergent for a minimum dwell time;
- (e) activating a pump to deliver water to the mixing chamber;
- and
- (f) circulating a mixture of the disinfectant or detergent and the water in the mixing chamber for a predetermined time thereby exposing an outer surface of the at least one medical device to the mixture.
A method for reprocessing a medical device contained within an enclosure, the enclosure comprising a liquid distribution system configured to deliver one or more fluids to the medical device, the method comprising:
- (a) activating a first pump to deliver a concentrated disinfectant or concentrated detergent from a first reservoir to an internal channel of the medical device;
- (b) deactivating the first pump and closing a valve in fluid communication with the internal channel once a select one of a time threshold and a volume threshold is achieved;
- (c) activating a select one of the first pump and a second pump to deliver a select one of water and a diluted disinfectant or diluted detergent to the enclosure where the medical device is configured to be contained such that the select one of water and a diluted disinfectant or diluted detergent is configured to contact an outer surface of the medical device;
- (d) releasing the concentrated disinfectant or concentrated detergent from the internal channel when the internal channel has held the concentrated disinfectant or concentrated detergent for a predefined dwell time, wherein releasing the concentrated disinfectant or concentrated detergent delivers the concentrated disinfectant or concentrated detergent to the enclosure where the medical device is configure to be contained such that concentrated disinfectant or concentrated detergent is configured to combine with the select one of water and a diluted disinfectant or diluted detergent to form a mixture;
- and
- (e) circulating the mixture in the enclosure for a predetermined time to expose the outer surface of the medical device to the mixture.
