PROBLEM TO BE SOLVED: To provide an insulin injector for inhibiting a person who suffers diabetes and takes an insulin shot from forgetting that the insulin shot has been already taken and erroneously taking the shot twice before meal.SOLUTION: Circuit components such as a cell (or a piezoelectric element), a capacitor (an electric storage element), and an LED (a light emitting diode) are incorporated into an injection button. By depressing an insulin injection button with a thumb in taking the shot, the incorporated LED is lit and performs display for a fixed time, and thus a user can determine that he/she has already taken an insulin shot.COPYRIGHT: (C)2012,JPO&INPIT【課題】糖尿病でインスリン注射を行っている人が、既に注射した事を忘れ、誤って2回の注射を食前に行うことを阻止するインスリン注射器を提供する。【解決手段】注入ボタンに、電池(又は、圧電素子)、コンデンサー(蓄電素子)、LED(発光素子)等の回路部品が組み込まれてあり、注射する際に親指でインスリン注入ボタンを押すことにより、組み込まれたLEDが一定時間点灯表示し、既に注射済である事を判断できる構成とする。【選択図】図1
