Ethos - FAQS

A: The only requirement is to perform bedside cleaning which is to remove the procedure cover or sheath from the probe with a wiping motion, removing any gross containments prior to insertion into Ethos. Ethos will clean and high level disinfect an ultrasound probe through a validated process. Using an Ethos limits staff interaction with the ultrasound probe, thus reducing handling and potential damage.

A: There is nothing like Ethos on the market. Ethos is more than just a disinfector, Ethos is a cleaner disinfector for transvaginal, transrectal, and surface ultrasound probes. It is the only US FDA cleared medical device that performs both the manufacturers’ required cleaning and high-level disinfection automatically. This is a great advantage as the process of cleaning is very labor-intensive and can be full of manual errors. If the probe is not properly cleaned, it can lead to high-level disinfection not occurring properly because the presence of foreign material can affect the efficacy of the high-level disinfectant. This interference can result in an undetected failure during the high-level disinfectant process resulting in the possibility of a healthcare-associated infection (HAI). Since Ethos automates both the cleaning and disinfection, the risk of an HAI is greatly reduced.

A: Yes and No, Ethos mixes the AquaCide cleaner disinfectant each time and requires validation of the MRC but the Ethos does this automatically within the device. No manual reading of test strips or other chemical indicators is required by the user.

A: In just 3 minutes, Ethos will clean and high-level disinfect a soiled endocavity ultrasound probe (transvaginal, transrectal, or surface ultrasound probe).

A: There will be water droplets on the probe at the conclusion of a cycle in Ethos. These should be dried off, using something like the QwikDry drying cloth. This step is important as the drying method should be one that does not reintroduce contaminate as the probe has just completed a high-level disinfection cycle with 5-nanometer filtered rinse water.

A: No, only AquaCide cleaner disinfector can be used in Ethos.

A: A factory trained CS Medical service technician.

A: No, Ethos is ready to operate when the staff member presses the “Clean and Disinfect” icon on the 7” color touchscreen. Ethos takes the staff member through the process of entering data about the probe and the user prior to having a fresh single-use bottle of cleaner disinfectant inserted into the Ethos. The AquaCide cleaner disinfectant is completely used during the reprocessing cycle and Ethos is ready for the next probe at the conclusion of each cycle, no sleep mode or downtime. Even if the Ethos has been turned OFF, wait less than one minute after being powered ON for Ethos to purge and run diagnostic tests and you will be able to start a cycle.

A: No, Ethos performs the cleaning and high-level disinfection followed by a cold, 5-nanometer filtered water rinse cycle. The probe will be extracted from Ethos at the conclusion of the reprocessing cycle at room temperature.

A: Yes, CS Medical offers the SelectCare365 (CS-ESC-365), which covers all parts and labor for repairs, also includes a SelectCare12 visit, and if your unit passes 5,000 cycles while the service contract is enforce, all aspects of SelectCare CheckPoint as well

A: MRC is confirmed, average temperature of clean and disinfect, and the clean and disinfect time

A: No, a surface disinfectant like Medi-Fect (PN CS-203100) should be used to sanitize and low level disinfect the probe cable and electrical pack of the ultrasound probe.

A: No the probe must be removed from the Ethos and dried according to the probe manufacturer’s directions. QwikDry (PN-CS-200880) single-use, gamma irradiated drying cloths come in packs of 100 and should be used to dry the probe before storage to prevent contamination.

A: Clean external touch surfaces, hinge, and door of the Ethos with a Medi-Fect wipe, as well as inside the door and the upper probe reservoir area.

A: No, the Ethos will pierce the AquaCide as it is inserted, protecting the end user from exposure and accidental spills.

A: First ensure there are no puddles of liquid on the ground around Ethos; then check to ensure the water, drain, power, and barcode scanner are all firmly plugged into Ethos.

A: Yes, per the CDC Guideline for Disinfection and Sterilization in Healthcare Facilities studies have shown that perforations in covers/condoms can occur up to 81% of the time.

A: Point of care ultrasonography (POCUS) is advanced diagnostic ultrasonography that is performed and interpreted by the attending physician as a bedside test. POCUS has been widely used in many disciplines as a rapid diagnostic tool, especially in emergency medicine. Moore C.L., Copel J.A. Point-of-care ultrasonography. N. Engl. J. Med. 2011;364:749–757. doi: 10.1056/NEJMra0909487.
