The use of the tampons made of hydrophilic materials while maintaining the function of nasal breathing allows avoiding the complications in the postoperative period, however, their use is complicated by the lack of domestic and high cost of the foreign analogues.

The aim of the work is to develop pneumatic nasal tampons made of hydrophilic materials while maintaining the function of nasal breathing.

Materials and research methods. Endoscopic examination of the nasal cavity was performed оn 100 volunteers (mean age 38.4±1.5 years, of which 58 were men (58%) and 42 women (42%)) with the determination of the parameters of the nasal cavity and nasopharynx. Based on the analysis of the data obtained, the sizes and design features of the nasal tampons are proposed. Substantiated material for the manufacture of nasal tampons. The absorption capacity of the nasal tampons was studied.

Results. The selected material for the manufacture of nasal tampons – cellulose. Based on the determination of the parameters of the nasal cavity, the optimal sizes of nasal tampons are proposed: TH2 (14×64×7 mm); TH3 (19×84×7 mm). The design features of the tampons have been determined. Тhe indications have been developed for the usе of certain types of the tampons. It has been proven that the nasal tampons have a high absorption capacity (1721.0±14.8%), which will ensure high-quality and effective hemostasis.

Conclusion. An import-substituting technology for the manufacture of the nasal tampons with preservation of the function of nasal breathing has been developed, what allows to ensure high-quality and effective hemostasis.
