8.
Use your hands to mould the mask to the side of the neck and the cranial area, including the
occipital bone. The ventral inferior line of the base of the skull is an optimal landmark to
mould. Hold the mask in position for 10-20 seconds to ensure an impression is formed.
9.
When the mask material starts to harden, you can use cold packs or cold wet towels to cool the
mask and speed up the setting process.
10.
While keeping the patient in the same position, let the mask
cool and set for at least 5 minutes. After 5 minutes,
the mask should have fully set.
5.2
MOULDING THE SUPINE FACIAL MASK
1.
Rotate the top part of the mouldroom tool to one side again so that it is not in the way when the
patient has to lie down.
2.
Lay the patient in the supine position with the head and shoulders resting on the occipital DSPS
mask, previously made.
3.
Take a new supine facial mask (perforated RayPRO thermoplastic mask with the white frame).
4.
Make sure that all the black sliding lock pawls are in ‘unlocked’ position as shown here.
5.a
When using a Waterbath (of min. internal dimensions, in mm: 665w x 575d x 80h - we recommend
using the MacroMedics MacroBath 4)
to heat the mask, set the water temperature between
68°C and 70°C (154.4°F and 158°F). Leave the mask in the water for approximately 1 to 2 minutes
until it becomes sufficiently pliable. Take the mask out of the waterbath and dry it between two
towels. Check the temperature of the mask before skin contact.
5.b
When using an Oven
to heat the mask, set the oven temperature between 68°C and 70°C
(154.4°F and 158°F). Leave the mask in the oven for approximately 4 minutes to 4 minutes and
30 seconds, until it becomes sufficiently pliable. Take the mask out of the oven and check the
temperature of the mask before skin contact. If the mask is too warm, cool it down before
placing it on the patient.
6.
Position the mask above the patient’s face, with the frame’s logo facing upwards.
7.
The nose hole should be positioned on the superior tip of the nose first. Stretch the mask down
slowly to the cradle rim in a smooth, continuous movement for even stretch of the material.
8.
When using a long hair mask, position the ponytail through the gap in the top of the frame of the
mask.
