Ultrasound decontamination: from probe to plug

In ultrasound, having one complete decontamination system to treat an entire device anytime, anywhere rapidly and effectively, is crucial.

Decontamination must consider all parts of a device including the probe shaft and handle, the cable, the plug, the probe holder and controls. This is confirmed by published guidance and science.

HTM 01-06: Decontamination of Flexible Endoscopes. Part C: Operational Management, 3.68 states: "The electrical cable and plug socket can similarly become contaminated. Therefore, the whole of the probe – not just the insertion tube – should be carefully cleaned followed by wiping with disinfectant.” 

HIS guidance for the decontamination of intracavity medical devices advises that: “Other surfaces (controls, keyboards, electrical connectors, etc.) may have sequential contact with an operator’s contaminated gloved hands and the probe.” 

In addition, Potential infection control risks associated with ultrasound equipment – a bacterial perspective. WFUMB (ASUM) also states: “Infection control processes for ultrasound focus on the probe, but we have also shown that probe cords and machine keyboards present significant sources of infection and that this can include potential pathogens.” 

Tristel advises that UV and H2O2-based machines cannot treat the entire device. The dimension and shape of their chambers are designed to minimise the chemical needed to fill the chamber or the light rays needed to flood it, and these enclosures are only large enough to accommodate the probe. The cable and plug which connect the probe to the console will not fit into the machines and their chambers. The holder in which the probe is located on the console is also neglected. 

Ultrasound is in a constant state of evolution 

Probe shapes and dimensions are ever-changing. If the chambers of machines cannot fit the entire probe in, then it can touch the side of the chamber. A consequence of this would be that the chemical mist or the light ray may not reach every surface of the probe. If an ultrasound manufacturer’s probe simply does not fit the chamber, an alternative high-level disinfection process must be purchased. In this instance, machines are not adaptable and therefore not future proof.
