Compatibility of the Omnican (R) Pen Needles with Insulin Pens, Humapen (R) and Novopen (R)

Abstract

This study was carried out to assess accuracy of Omnican (R) insulin pen needles (29G and 30G) by measuring the weight of insulin delivered in each of 10 depressions of the plunger comparing these using other pen-injectors (Humapen (R) and Novopen (R) for each gauge. We found that the needle-to-needle variation was not statistically significant when the needles were used to dispense insulin using either of the insulin pens (Humapen (R) and Novopen (R). HumaPen (R) insulin pen was found to deliver the insulin closer to set target volume using either gauge (29G and 30G) of the Omnican (R) needles in some of the insulin ranges used in this study
