Comparative User Experiences With BD Nano™ PRO 4mm x 32G Extra Thin Wall Pen Needle vs Three Commercially Available Pen Needles

The study will consist of one 60 to 120 minute visit in which pre-set doses of saline will be abdominally delivered by Subjects via a reusable insulin pen device. All pen needles will be attached by study staff. The pen needle outer cover and inner shield will be removed prior to subject use so that they will not be able to identify which device they are using. Subjects are to perform 12 injections into the abdomen (6 pairs of injections). Pairs of injections will be evaluated and each pair will contain one BD Nano™ PRO and one comparator pen needle. Within the 12 injections, each comparator will be injected twice, therefore each subject will experience 2 of each of the following pairs:

Inclusion criteria

• Adults 18 to 75 years of age (inclusive)
• Diagnosed with Type 1 or Type 2 diabetes

Exclusion criteria
