Glucose meter in pink protective case

I lost my glucose meter yesterday around 3pm. It's a white Accu-Chek model with a pink silicone protective sleeve, about the size of a small remote. There’s a tiny dent on the top edge and a coffee stain on the sleeve. I was near the Flatiron Building on Fifth Ave around 23rd St, and I think I dropped it on the sidewalk outside the cafe on Broadway. This meter is essential for my daily diabetes management, and I really need it back.
