M/s. Okano industries planned to make a needle that is painless.
Usually the tip of the very thin pipe formed beforehand is sharpened by tapering it to a point, but M/s. Okano industries established a new needle manufacturing process by taking a flat sheet and making into circular shape, and succeeded in developing the "Painless injection needle" of taper shape that is thinnest in the world.
While the tip of the usual injection needle is 0.4mm, the "Nanopass 33" of M/s. Okano industries is half of that 0.2mm.
At present more than thousands of injections are given in a year exclusively for diabetic patients. If this 0.2mm needle is used all over the world sooner or later, then even the children may not dislike the injection.
The sale of "Nanopass 33"was started as an injection needle for diabetic insulin in 2005, and the regular export to China was started from 2011.
M/s. Okano industries manufactures the needle, and the medical device manufacturer M/s. TERUMO sells it.
