摘要：
The utility model refers to a medical technique, in particular, to a medical instrument intended to supply a medicament to an area of action, for example a nasopharynx, in the form of an ionized aerosol.The task of developing the proposed waveguide is to increase the effectiveness of nasopharyngeal treatment in patients with inflammatory, subatrophic and hypertrophic diseases with oropharyngeal access using the properties of low-frequency ultrasound.The object of the invention is achieved in that the device consists of an end portion in the form of a cylindrical rod with a thread for connection to an acoustic assembly and a working part passing over a conical surface to an operating end in the form of a cylindrical rod having a central axial channel with an internal thread , communicating with the lateral channel in the drug supply attachment on the working end and the outlet channel for its exit in the form of an aerosol, characterized in that the outlet channel is formed by at an angle of 75 degrees to the central axial channel, looks like a truncated inclined circular cone with an internal cut with a larger side facing the working end at the tip of the waveguide. The top of the working end has a hemispherical shape, and the waveguide itself is two-half wave.The achieved technical result consists in expanding the arsenal of means for ultrasonic drug delivery through the oral cavity to the zone of action - on the mucous membrane of all the walls of the nasopharynx, including the zone of tubal tonsils, the mouths of the auditory tubes and adenoid vegetations, taking into account the different types of anatomical structure of the nasopharynx.Полезная модель относится к медицинской технике, в частности, к медицинскому инструменту, предназначенному для подачи лекарственного средства в зону воздействия, например в носоглотку, в виде ионизированного аэрозоля.Задачей разработки предлагаемого волновода является повышение эффективности лечения носоглотки у пациентов с ее
