In order to be more convenient to measure syringe scale. We design a transparent plastic ball attached to the syringe. The transparent ball can enlarge the calibration of syringe scale. There are serial benefits for the transparent plastic ball. First, visually impaired older people no longer need to wear reading glasses to use syringes. Second, it can increase the accuracy for the volume of the medicine inside the syringe. In addition, different colors of rubber ring so the ball can move up and down, and also can be used as the distinction between different medicines.

Convex lens can make enlarge virtual image. It can make the calibration clearer.  For example, old people may have visually impaired. They need to prepare different glasses. Easy check syringe can solve this problem.

 

Injection of insulin is a daily route for the patients of diabetes. Easy check syrings will make the situation more convenient. My aunt is a diabete and every time she inject insulin that she cant see the scale clearly because she presbyopia and myopia. So, I design easy check syrings for her.
