Step [2]: Prepare Bresle Method Patch
Option A: DeFelsko PosiPatch
a) Turn the PosiPatch and magnetic ring upside down. Place the PosiPatch into the magnetic
ring ensuring the arrows align with the injection port. Do not touch the PosiPatch’s interior.
b) Carefully place the magnetic ring on the steel surface. When used on vertical surfaces,
position the port between the 2 o’clock and 10 o’clock points before attaching the ring to the
surface.
c) Slowly inject 3.0ml of DI water into the port using the plastic dispensing tip. The air within the
PosiPatch automatically escapes through the air-permeable membrane.
(a) (b) (c)
When used on horizontal surfaces, fully insert the dispensing tip into the PosiPatch. On vertical
surfaces, insert the dispensing tip only as far as is needed to see the tip inside the PosiPatch.
Option B: Bresle Method DeFelsko Patch (or equivalent)
a) Remove the backing and foam center from the patch, taking care not to touch the interior
surface.
b) Press the patch firmly onto the surface making sure most of the air escapes.
c) Pierce the top of the patch at the foam perimeter, allowing the needle to penetrate into the
center of the patch.
(a) (b) (c)
d) Inject half of the water into the patch. Then, use the syringe to withdraw trapped air.
e) Remove the needle, point it upwards and expel the air.
f) Re-insert the needle and inject the remaining water into the patch.
