3. Instructions for Use

VISITRAK Grid

1. Remove the white backing layer from
VISITRAK Grid (Diagram A)
A
and place the sterile grid area over the
wound (Diagram B).
B
Position the top of the tracing grid in the
direction of the patient's head.
2. Trace around the edge of the wound margin
onto the grid using a permanent marker pen
C
(Diagram C). Care must be taken to remain
within the grid area.
Extra functions:
Trace around the perimeter of any viable or
non viable tissue using the same tracing grid.
Viable tissue includes areas of epithelialisation
or granulation. Non-viable tissue includes
necrotic or sloughy areas.
If the wound is too large to fit within the grid
area of one tracing grid, overlap two tracing
grids and trace the wound across both tracing
grids (Diagram D).
D
(This will produce two separate semicircular
tracings whose areas will need to be added
together).
3. Remove the contaminated wound contact
layer from the tracing grid by peeling quickly
and carefully. (Diagram E).
Dispose of as clinical waste.

4. Complete the patient identification and
assessment information on the tracing grid
(see 'Symbols Guide').
5. Place the tracing grid on the surface of the
VISITRAK Digital unit (Diagram F), fitting the
holes in the tracing grid over the pegs on the
unit surface.

VISITRAK Digital has a power save function if
the tablet is not touched for 3 minutes. This is
indicated by the display showing the cursor
move across the screen.Touch the tracing grid
with the stylus and the unit will reactivate. If
VISITRAK Digital is not touched with the stylus
for 8 minutes, it will automatically power down
and will have to be switched on using the
power button.

Calculating a Single Wound Area

9. If available, place the coversheet on top of
the tracing grid and secure over the pegs on
VISITRAK Digital. Hold coversheet/VISITRAK
Grid securely on the surface of the unit, place
the stylus at the start point of the tracing.
Press the side switch on the stylus (this
should be done in close proximity to the grid)
until the tracking symbol appears on the
screen.
The segments of the display will illuminate in
sequence indicating that the digital tablet is
ready to collect and process data.
10. With minimum pressure retrace the wound
outline on the grid without lifting the stylus,
starting and finishing at the same point and
without going outside the grid area. The unit
will BEEP to show that the trace is complete.
When processing is complete the device will
BEEP and display the area measurement in
cm 2 in the digital display.
88.9

Note: If the unit double BEEP's, an error has
been made whilst retracing the wound area.
Refer to the Troubleshooting section.
11. Write the area measurement in the 'area'
box on the tracing grid.
Touching 'C' momentarily at this point will
erase the area measurement.

To continue repeat steps 9 and 10.
Note: Do not maintain contact with the 'C'
button unless you wish to reset the unit.
If the stylus is not in contact with VISITRAK
Digital for 3 seconds, the display will auto
scroll and show the length and width
measurements automatically for 2 seconds
each. Selection of the function boxes or 'C' will
stop the auto scroll. The scrolling function will
only restart after selecting the area, length or
width boxes.

Displaying Length and Width

12. After the original area has been calculated

e.g. 88.9cm , touch the box under the length
or width symbol on the tracing grid with the
stylus, to display the length or width in
centimetres, as required.
