The paper presents comparative analysis of several types of ultrasonic spray devices of liquid (their structure and operating principles) in order to create our own ultrasonic nebulizer of liquid in particular ultrasonic nebulizer of insulin as well as conditions of its exploiting by people suffering from diabetes. The development of ultrasonic nebulizer of insulin is aimed at eliminating a number of problems connected with regular insulin taking (injections). They are increasing the effectiveness of treatment for patients with diabetes (possibly accelerating treatment), replacing the painful way of insulin delivering (via injections) with the device through which the medicine will be delivered and reducing the consumption of an active drug based on insulin. Nowadays insulin ultrasonic nebulizer is one of the new ideas in the field of medical technologies. There are some experiments on the insulin inhalator implementation. However, tests have been conducted for a long time but there still hasn’t been wide application. Operating principle of the ultrasonic nebulizer of insulin is fundamentally different from possible analogues, which are very few
