U međuvremenu sam dobila i objašnjenje:

blinding pen - a black paint pen (marker) for use in the masking of each film or image (to mask all patient identifiers on the film or deidentify the digital data).

Znači, u ovom kontekstu bi se moglo prevesti kao: flomaster/marker za maskiranje (podataka)
Svima puno hvala na trudu!

U ovom kontekstu (clinical trials) „blind/blinding“ se odnosi na sakrivanje ličnih podataka o pacijentu/ispitaniku:

„Paint Pens - For your use in blinding/masking confidential patient information on film or CD/ODs.
...
Do we need to blind information on images or can XY do this for us?
It is preferred that the site blind its own images prior to submission to XY; however if unblinded images are submitted, the images will be de-identified by XY.
...
The use of an unapproved blinding technique may result in the films being unable to be processed at XY.
...
Do not place tapes or stickers on the films as a method of blinding.“

To bi bila namena „blinding pen“, ali ipak ne znam tačno ni šta je to (tj. kako radi - blinding technique), pa naravno ni kako prevesti.
