🩺 Stethoscope is one of the animated emoji in Google's Noto Emoji Animation set — the same stethoscope emoji (U+1FA7A) drawn as a short looping Lottie animation. Lottie files are vector, so the animation stays sharp at any size and is usually much lighter than a GIF or a video.
🩺 is the stethoscope emoji, part of Unicode's Objects group, added in Emoji 12.0 (2019). Unicode's keyword list links it with “doctor”, “heart”, and “medicine”.
