Brief Summary
This study will focus on how different injection needles are perceived by patients. The needles differ in design and mechanical properties, and will be tested in people with Type 2 Diabetes. The measured parameters during and after needle insertion are: penetration force through skin (measured with force gauge), pain perception (rated on visual analog scale, VAS, on a scale from 0 to 10), and skin blood perfusion at insertion site (measured with laser speckle contrast scanner). Furthermore, any skin reactions will be recorded.

Outcome Measures
Primary Outcomes (2)
Pain on 0-100 mm VAS
Pain from the needle insertions will be assessed by a 0-100 mm Visual Analog Scale where 0 mm is "no pain" and 100 mm is "worst possible pain".
Immediately after needle insertion.
Area under curve (AUC) of skin blood perfusion increase
Skin blood perfusion will be measured using Laser Speckle Contrast Analysis which measures the skin's perfusion in an arbitrary unit called Perfusion Units (PU). The increase in skin blood perfusion for 15 minutes after needle insertion is measured as AUC.
Change from baseline (before insertion) to after insertion with continuous measurements for 15 minutes.
Secondary Outcomes (2)
Needle peak penetration force [N] through human skin
At time of needle insertion
Skin reactions (bleeding, bruising, redness, swelling) on a scale from 0 to 4.
0.5-1 hour after insertion and 20-24 hours after insertion
Study Arms (1)
Subcutaneous insertions of needles
EXPERIMENTAL36 subcutaneous needle insertions per participant with 18 differently designed needles. 30test participants in total. No fluid will be injected. Pain perception will be rated by the subjects, penetration force and skin blood perfusion will be measured, and any skin reactions will be assessed.
Interventions
Various types of needles with different designs and mechanical properties. Five marketed needles are included: NovoFine 28G x 12 mm (Novo Nordisk A/S, Denmark), NovoFine 30G x 6 mm (Novo Nordisk A/S, Denmark), NovoFine 32G tip x 6 mm (Novo Nordisk A/S, Denmark), BD Ultra-Fine 32G x 4 mm Pentapoint (Beckton, Dickinson \& Company, USA), and Terumo Nanopass 34G x 5 mm (Terumo, Japan). Ten needles have been exclusively manufactured for this clinical trial by Hart Needles, USA. These needles vary in diameter, number of needle tip grinding, and angles of grindings. Three needles have been modified from the original (NovoFine 32G x 6 mm) with lack of lubrication or damaged needle tip for simulations of repeated use. No drugs are injected. Only the needle insertion is evaluated.
Eligibility Criteria
You may qualify if:
- Participation in the study is possible if you
- Are a man or woman with type 2 diabetes. An equal distribution of men and women is sought to compare findings between the sexes.
- Take daily injection(s) of anti-diabetic medicine (insulin or glucagon-like-peptide-1 (GLP-1) analogues) with a pen or syringe, and have done so for more than 6 months.
- Are 18-70 years (both included)
- Are slightly overweight, i.e. BMI 25-35 kg/m2.
- Are inactive for at least 6 hours before the study, i.e. transport to the investigation must be carried out without significant physical activity.
- Have no significant body hair on the abdomen (can be shaved away, and if so, this should be done at least 48 hours before the test day)
You may not qualify if:
- Participation in the study is not possible if one or more of the following criteria are met:
- Known or suspected hypersensitivity to needles, including the needle's lubricant (typically silicon oil), pen / ink color, or other materials that come into contact with the injection site
- Previous participation in the trial
- Intake of medical product which may influence pain perception within the last 14 days before trial
- Insulin pump user
- Previous surgery in the abdominal wall
- Intake of any painkillers within the last week before the test (low-dose aspirin in cardiovascular prophylactic doses is allowed)
- Known active or inactive skin diseases in the abdominal area that may influence pain perception or blood perfusion
- Anticoagulant therapy within the last month (low-dose aspirin in cardiovascular prophylactic doses is authorized, except on test day)
- Pregnant or breastfeeding
- Consumption of alcohol within the last 24 hours before the test
- Intake of drugs within the last 48 hours before the experiment
- Smokers and ex-smokers who use nicotine products (allowed if not used within the past 6 months prior to study entry)
- Moderate to severe lipodystrophy
- Severe neuropathy (grade 0/8, 1/8 or 2/8). This is examined with a Rydell-Seiffer tuning fork.
