FIELD: otorhinolaryngology.SUBSTANCE: under endotracheal anesthesia, an endoscope equipped with optics and an instrument for removing pathological contents of the maxillary sinus are inserted into the nasal passage. The inferior nasal concha is displaced medially using a raspatory. Then, stepping back from the edge of the piriform opening by 1.5–2.0 cm in the caudal direction, a mucoperiosteal flap of the lateral wall is separated in the lower nasal passage. The mucoperiosteal flap is displaced posteriorly, exposing the bone skeleton in the projection of the inferomedial angle of the maxillary sinus. Next, using a cold plasma coblator, in ablation mode, the mucous surface of the bone skeleton is evaporated for 2–3 seconds, followed by coagulation of small vessels. Then, a bone valve measuring 10–15 mm is formed from the exposed bone skeleton. The bony valve is retracted in the caudal direction, forming an antrostomy. A 70-degree endoscope is inserted through the formed antrostomy and the pathological contents of the sinus are visualized. In this case, if the cyst is visualized with a coblator in ablation mode, the cyst is evaporated along with its contents, and the remaining cyst is captured and removed. If a polyp is visualized, the polyp stalk is first evaporated, and then the remaining part of the polyp is removed. If a foreign body is visualized, it is removed with forceps. In this case, if the foreign body is encapsulated or located in the thickness of the mucosa, a coblator in ablation mode evaporates part of the mucosa until the foreign body is exposed, and then removed. Next, the sinus cavity is washed with saline solution. The antrostomy is closed with a bone flap. The formed mucoperiosteal flap is placed back in its original place.EFFECT: method allows for endoscopic endonasal removal of pathological contents from the maxillary sinuses with a minimal risk of cyst / polyp recurrence and postoperative complications, reduced blood loss during surgery, shortened surgical time, postoperative rehabilitation periods, and temporary disability.3 cl, 3 ex

This invention discloses an intelligent, adaptive local oxygen supply system and its control method, belonging to the technical field of oxygen supply auxiliary equipment. The system includes an oxygen supply module, a target tracking module, an adaptive air delivery module, and a control module. The target tracking module acquires the spatial coordinate information of the user's face or nasal cavity area in real time; the control module generates a pointing command based on the spatial coordinate information, driving the adaptive air delivery module to perform displacement compensation, ensuring the oxygen jet direction is towards the target area. Furthermore, the system, through a respiratory rhythm monitoring module in conjunction with a throttle switch, closes the throttle switch during the exhalation phase and accumulates pressure in the buffer pressurization container; during the inhalation phase, it triggers the throttle switch in advance to release pressurized oxygen based on the airflow flight time difference calculated by the infrared ranging module, achieving synchronous coverage of the oxygen jet and the inhalation peak. This invention can automatically adjust the air delivery direction according to changes in the user's position and match the respiratory rhythm for intermittent pressurized oxygen supply, effectively improving oxygen utilization.

This utility model relates to the field of medical device technology and discloses a nasal mask for a ventilator, comprising a facial pad, a mask body, and a curved tube arranged sequentially. The first end of the curved tube is configured as a guide shaft, and the curved tube is assembled into the mask body through the guide shaft, so that the central axis b of the guide shaft is arranged towards the facial pad and towards the area between the vermilion border of the upper lip and the nostrils. Based on in-depth research on airflow distribution patterns and user facial structure, the position of the airflow outlet of the curved tube is lowered, changing the airflow direction and range while keeping other conditions unchanged. The improved curved tube can greatly reduce the airflow delivered to the face from covering the tip of the nose and distribute it in a suitable area around the nasal cavity, which can not only meet the user's breathing needs and ensure that the airflow can smoothly enter the nasal cavity, but also avoid the uncomfortable impact of the airflow on the skin of the tip of the nose; thus solving the technical problem of discomfort caused by the use of existing nasal masks for ventilators.
