Due to its simplicity and efficiency peristaltic drips [1] are widely used in a wide variety of treatments in medical practice [2]. Drip sensors used along with the drips provide step-infusion of medications and reduce the influence of the human factor. Infusion rate of medication plays one of the key roles in the treatment process [3], [4], so it is necessary to ensure that the drops sensor adequately detects the state of the drip camera when dripping speed is from a few ml/h to a few hundred ml/h. Three types of drop detectors are examined. Their main advantages and disadvantages are given.
