1. Introduction VISITRAK is a wound measurement system comprising three components: VISITRAK Digital
Battery powered digital measuring tablet with stylus.
VISITRAK Grid
Single use, 3-layer tracing grid.
VISITRAK Depth
Single use, foam tipped, sterile depth indicator.
VISITRAK enables the measurement of wound dimensions (area, length, width and depth) producing a visible record of the dimensions of a wound. The digital tablet converts a line tracing into a true area measurement and can be used to calculate the % area change from the last area measurement. It is also possible to measure the % non-viable tissue (or other regions in the wound). VISITRAK is portable, easy to use and can be used from patient to patient.
Warnings and Precautions VISITRAK Digital • Do not use the coversheet within / on a wound. • Do not use VISITRAK Digital in a wet environment. Serious electrical damage may occur. • Do not use VISITRAK Digital in the presence of flammable mixtures. • Do not take apart VISITRAK Digital. • Do not sterilise VISITRAK Digital. Damage or destruction to the device may result. • Minimal pressure should be applied when tracing the wound outline onto the VISITRAK Digital with the stylus. CAUTION: Misuse of the device will cause inaccurate measurement and potential damage.
VISITRAK Grid • Do not fold or crease VISITRAK Grid. • Not all pens are suitable for use on the tracing grid. Ensure that a permanent marker pen is used. • Use minimal pressure when using a pen to trace the wound edge. • Do not touch the surface within the sealed Indications for use area of VISITRAK Grid. This surface will VISITRAK is indicated for wound area come in direct contact with the wound. measurement and can be used on all wound • Do not use the product if the seals are types. VISITRAK Digital is indicated for use opened or damaged. only with VISITRAK Grid and VISITRAK Depth. VISITRAK Digital will only function with the VISITRAK Depth attached stylus. • Do not bend VISITRAK Depth. • Only insert the foam tipped end into the wound. • Rest the tip on the wound bed using minimal pressure. Care should be taken not to depress the wound bed.

4. Troubleshooting You notice
Possible causes
Solution
The function symbol on the tracing grid has been touched but the unit display has not changed.
Function symbol touched instead of the box below the function symbol.
Touch the box underneath the appropriate function symbol on the tracing grid using the stylus. Do not press the side switch on the stylus.
Area measurement does not appear in unit display. Unit double BEEP’s during/after tracing is complete and unit display flashes cm2 previous area reading.
Incomplete tracing on digital tablet, which may be due to: • The side switch on the stylus has not been pressed close enough to the unit surface. • Tracing did not finish in the same place as it was started. • The stylus has been lifted during tracing or some point of the line has been repeated. • The stylus/tracing has overlapped the grid area. • The grid slipped on the VISITRAK device surface during tracing of the wound outline.
Fit the holes in the tracing grid over the pegs on VISITRAK Digital. If available, place the coversheet on top of the tracing grid and secure over the pegs on VISITRAK Digital. Hold the coversheet/tracing grid on VISITRAK Digital surface using the unoccupied hand. Press the stylus side switch in close proximity to the tracing grid, and place the stylus at the start point of the tracing to activate the tracking symbol in the display. Trace the wound outline on the grid, whilst ensuring that minimum pressure is applied to the grid by the stylus. Do not lift the stylus while tracing and remain within the grid area. Start and finish the tracing at the same point. You will hear an audible BEEP to indicate a successful trace.
No length or width results available.
Multiple tracing grids have been added together. The length and width parameters cannot be displayed following these functions.
For large wound areas requiring multiple tracing grids, only the wound area can be measured.
The display screen shows the cursor moving across the screen.
The digital unit has an automatic power save (sleep) function if not touched after 3 mins with the stylus.
Touch the tracing grid with the stylus and the unit will reactivate. Proceed with the next function.
The battery symbol flashes on and off and subsequently remains on permanently. The unit cm2 double BEEPs
The batteries have reached a level which is approaching unacceptable for the unit to function.
The unit will not switch ‘ON’ and the display remains blank.

Cleaning Procedure
Clean VISITRAK Digital, stylus and coversheet in accordance with standard infection control procedures, or as below: 1. Wipe down all device surfaces using a damp soft cloth and a low level disinfecting solution. 2. Dampen another soft cloth with clean water and use this to wipe down all surfaces to remove the disinfecting solution. 3. Dry with a separate soft cloth. Do not immerse any part of VISITRAK or use a dripping wet cloth for cleaning. Do not sterilize the VISITRAK Digital or stylus, damage or destruction may result. Do not use plastic solvents or abrasive cleaners.
