We received a picture series from Becton Dickinson (Fig. 1A, here transformed to black and white and translated from Swedish) showing how syringes look after one, three, and five injections. We were astonished at how deformed the syringes were after a few injections.
To test the reproducibility of the syringe deformation, one physician and two nurses, all with ordinary builds and without scars or metal implants, tested Becton Dickinson’s insulin pen syringes Micro-Fine+ 31 gauge × 8 mm. We used the syringes 1, 3, 5, and 10 times for injections in the abdominal fat. One syringe was thereafter used to penetrate an ordinary rubber mousepad 100 times, then to cut into a wooden computer table, and, finally, to cut a metal lamp foot. Pictures were taken of the syringes with a Zeiss Axioscope 2.5× lens with a lateral light source and a Canon 10D camera with 6.2 mpx resolution. The only syringe that looked similar to the used syringes in Becton Dickinson’s picture series was the one that cut into a metal lamp foot. The syringes used 0, 1, 3, 5, 10, and 100 times are without distortion of the tip (Fig. 1B).
Hence, Becton Dickinson has improved the quality of their insulin syringes dramatically since the pictures were published, the syringes have been manipulated to produce false evidence of syringe defects, or Robocop was used as a test subject.
