2 Introduction to the AuditPro System

Nanosonics AuditPro is an infection control workflow compliance management system, which incorporates the following advantages:

•   It standardizes ultrasound infection prevention practices;
•   helps meet accreditation requirements; and
•   delivers best practice patient care across facilities and organizations.

The automated and secure system combines clinician infection prevention decision making with infection control workflow data and a Patient Procedure ID. Figure 1 below shows the process workflow of the AuditPro system, including the interaction of the devices and software used.

Nanosonics AuditPro also guides the operator to ensure that the disinfection procedures follow the Spaulding Classification, as well as relevant country regulations, standards and guidelines.

All data is stored in secure AWS cloud environments that are HIPAA and GDPR-compliant, with fast access and secure backup.

The Nanosonics AuditPro system is intended to integrate with trophon2. For further information on the trophon2, see [2].

Nanosonics AuditPro is not compatible with the trophon EPR devices, the first generation trophon device.


2.1 The Nanosonics AuditPro System

This section describes the Nanosonics AuditPro system hardware and software components which are designed to be used with the clinical workflow at point of care, such as within patient examination rooms.


2.1.1 Physical devices

The Nanosonics AuditPro package contains:

    •  1 x Nanosonics AuditPro Mobile Scanning Device

See Nanosonics Mobile Scanning Device

    •  1 x USB (5 volt) power supply
    •  1 x regional mains connector
    •  1 x 1.2m (3.9 ft) USB to micro-USB cable
    •  1 x Nanosonics AuditPro docking station.

Figure 2: Nanosonics AuditPro System

Optionally, trophon2 devices may be ordered with your Nanosonics AuditPro package.


There are additional physical devices and networking infrastructure required to run AuditPro which are not included in the AuditPro package and are listed in the following subsections below. Additional Nanosonics Devices

The following Nanosonics devices (depicted in Figure 3) are required to use the AuditPro system:

•   trophon2 device
•   trophon AcuTrace Medical Instrument Tags
•   trophon AcuTrace Operator Card

Figure 3: Additional Nanosonics Components


During the operation of the trophon2 device, the trophon AcuTrace Operator Card and Medical Instrument Tags uniquely identify the operators and probes being used. This is achieved through programming the relevant fields onto the RFID tags or cards.

For more information about trophon AcuTrace Operator Cards, Medical Instruments Tags and their use with trophon2, see [2].

Reliability of the reprocessing data collected depends on a unique one-to-one correspondence between:

•   Operators and their trophon AcuTrace Operator Cards
•   Probes and their trophon AcuTrace Medical Instrument Tags

Not doing so may compromise the traceability of the Operators and Probes using trophon2 devices. Networking Infrastructure

A facility needs to have appropriate devices and networking capabilities to optimise the function of the AuditPro system.

The client should provide the following IT infrastructure:

•   Ethernet cabling to connect trophon2 devices to the facility ethernet ports
•   Further networking devices for Wi-Fi connectivity of the trophon2 devices (e.g. switches, routers, Wi-Fi access             points)
•   1 x computing device with compatible web browser to access the internet. (See Compatible Browsers)

Figure 8: Wi-Fi Settings Other Device Settings

The Settings screen Figure 7-4 allows you to adapt the Mobile Scanning Device to your needs.
Settings which may be useful are:

•   Sound level
•   Display brightness
•   Screen timeout Mobile Scanning Device Application Updates

The Mobile Device Management (MDM) application will maintain the software and SSL Certificate on the Mobile Scanning Device, as necessary.

Updates may include:

•   The operating system or its components
•   Security patch
•   Nanosonics AuditPro Mobile Application

The MDM checks the mobile application version when registering a new Mobile Scanning Device to a facility. It may take about 5 minutes (depending on your network speed) to update the application before you can register the Mobile Scanning Device.

Procedures can continue to be logged during update. It is recommended that the user reboots the device as soon as possible after updates have installed to access new features and improvements to the software.


The update process takes one of two paths, depending on the criticality of the update:

1.  Regular update process - No critical issue, minor feature updates.
The process will:

1.1. Send a message to the Mobile Scanning Device and an email to the Facility Administrator containing details of             the update and update schedule 72 hours ahead of the update.
1.2. Download and install the update silently in the background.
1.3. Provide an option on the Mobile Scanning Device instructing the user to reboot the device to complete the                 installation of the patch.


See Regular Update Process Workflow for a user view of this process.


2.  Critical update process - Major vulnerability detected, needs immediate update.
This process will:

2.1. Send a notification to the Mobile Scanning Device and an email to the Facility Administrator containing details of         the update and the update schedule 72 hours ahead of the update.
2.2. Download and install the patch silently in the background.
2.3. Automatically reboot the device, no user action required.

Note that this type of update will be scheduled outside normal working hours as much as possible to avoid interruption.

Once you receive notification of an update (during the notified update schedule) you must ensure that the Mobile Scanning Device:

•   remains powered on until the update has taken place
•   is connected to its charger
•   is connected to the Facility network. Mobile Scanning Device Messages

Messages are sent to your Mobile Scanning Device when there is a mobile application or kernel patch update. A notification will be displayed on the top right corner of your Mobile Scanning Device screen. Notifications are visible once the device is unlocked using the PIN.

To access these messages, tap the message notification on the top right of your screen. Figure 9 gives an example of a message page.

Figure 9: Message Page Regular Update Process Workflow

An example of a software update that requires operator interaction to reboot the Mobile Scanning Device is described below.

To Reboot the Mobile Scanning Device after an update:

1.  When a software update is taking place, a symbol next to the Wi-Fi icon on your lock screen will appear (see               Figure 10-1)
2.  When the update has been downloaded and is ready to install, a message to that effect will appear on your lock         screen (see Figure 10-2)
3.  Unlock your Mobile Scanning Device. A symbol on the top left corner of the screen will indicate a pending                   message (see Figure 10-3)
4.  Swipe down from the top of the screen to reveal the message. (See Figure 10-4) The Mobile Scanning Device can       be rebooted by tapping Reboot or by using the Power button on the left side of the device, see Figure 4 Side             View ⑦.
