Premature birth can be a cause for different diseases, to face this problem there are already existing ventilation supports in the clinical practice. For example, nowadays one of the approaches to treat neonates with respiratory diseases is using high-frequency jet ventilation in tandem with conventional ventilator. HFJV delivers high frequency breaths with the tidal volumes compared to the anatomical dead space, while expiration is passive due to chest recoil. Meanwhile conventional ventilator provides continuous pressure of air inside the lungs, keeping the respiratory system from collapsing. Continuous positive airway pressure ventilator can provide everything CV does in this ventilation circuit. Both respiratory support systems require a connector for the LifePort adapter of the HFJV to function. Since already existing versions of this connector for CPAP or CV and HFJV have some disadvantages concerning the high internal volume, it adds up to increasing the total dead space of the ventilation circuit. Increased total dead space consecutively increases the work of breathing of the patient. In case of prematurely born neonates, high work of breathing can cause a respiratory stress and develop into more severe complications. Therefore, the main aim of the thesis was to design the connector that would tolerate spontaneous breathing of the patient and have the least dead space possible, to reduce the total dead space of the ventilation circuit. This would lead to the reduction of the work of breathing of the patient. Multiple solutions of the problem were introduced, printed, and tested on the lung simulator. Work of breathing of the patient was evaluated and compared to already existing CV circuit to prove the efficiency of offered designs.
