Skin Tag Biopsy Pad

Skin Tag Biopsy Pad
Shown are 3.5x4x1 inch skin tag biopsy pads. They are used by the College of Nursing to teach how to administer punch biopsies on various sizes of skin tags.

Ingredients

  • Dragon Skin Part A (Smooth-on) 70ml
  • Dragon Skin Part B (Smooth-on) 70ml
  • Dragon Skin Part S (Smooth-on) 35ml
  • Mold Release (Smooth-on)
  • Flesh Pigment (Smooth-on)
  • Plastic Cups
  • Stirrers
  • Scale
  • Baby Powder
  • Skewer or Thin Stick
  • 3d Printed Skin Tag Biopsy Pad Mold (STL in downloads)

Instructions

  • Thoroughly spray mold release into the mold, making sure to get all the crevices and corners
  • Put plastic cup on scale and tare the scale
  • Pour 70 ml of Part B into the cup
  • Insert desired pigment into the cup until you reach the desired skin tone
  • Use a stirrer and mix the pigment and Part B together (leave stick in the cup)
  • Tare the scale again
  • Pour 35 ml of Part S into the cup. Thoroughly mix together until fully combined, making sure you scrape down the sides of the cup.
  • Tare the scale again and spray the mold with mold release a second time.
  • Pour in 70 ml of Part A, and thoroughly mix making sure there are no clumps or pockets of unmixed dragon skin.
  • Once completely combined, take a skewer or thin stick and dip it into the dragon skin. Then dip that stick into a hole of the biopsy mold.
  • Do this for all of the holes, making sure to pop all bubbles that may rise in the holes. You can also hit the mold on the table a couple of times to make the bubbles rise. Keep in mind that there is a 12 minute pot time before the mixture starts to cure.
  • Once you ensure there are no more bubbles in each of the skin tag holes, pour the rest of the mixture into the mold. Hit the mold on the table a few more times for good measure.
  • Let the part cure completely for 40 minutes.
  • Pull the biopsy pad out of the mold carefully to keep from tearing the skin tags.
  • Use a paper towel to wipe off any mold release residue left on the part.
  • Once dry, put baby powder on the foot to remove tackiness and to give a flesh-like feel.
