Abstract
Compatibility of two types of needles with a variety of durable and prefilled injection pens for diabetes medication was tested by attaching the needles according to ISO 11608-2 and verifying penetration into the cartridge using air shots and two-dimensional X-rays. NovoFine and NovoFine Autocover attached correctly to 20 and 19 out of 21 pen types, respectively. Neither needle type attached to Diapen 3.1/3.2, while NovoFine Autocover attached to most, but not all of OptiSet pens.
