Nanopass® 34G

Virtually painless insulin injection

Diabetes patients have long been in search of virtually painless insulin injection.

Terumo has made this possible with the advanced NANOPASS 34 - the world’s thinnest pen needle* with a diameter of only 34G.

NANOPASS 34G reduces pain through several advanced technologies.

*Based on research by Terumo Corporation in August 2012

World's thinnest pen needle "34G"

NANOPASS 34 is 22% thinner than 32G.

  • Pain is primarily related to needle thickness. There are 100-200 pain receptors per cm² human skin surface. NANOPASS 34 decreases the probability of touching the pain receptors and therefore makes the insulin injection virtually painless.
  • NANOPASS 34 causes less skin trauma than larger needle sizes, which results in less pain.

Asymmetric edge

The unique asymmetric edge of NANOPASS cuts the skin instead of puncturing it.

This decreases the resistance while penetrating the skin. Another step towards virtually painless insulin injection.

Slim double tapered shape

The patented slim double tapered needle shape reduces the insulin injection force significantly.

Although the needle tip is 34G, NANOPASS 34 provides less injection force than a conventional 32G pen needle*.

NANOPASS 34 combines virtually painless injection with easy handling.
