Right double-lumen bronchial catheter

Abstract

The invention discloses a right double-lumen bronchial catheter. The bronchial catheter comprises a left catheter body and a right catheter body. The left catheter body and the right catheter body are arranged side by side, connecting joints are installed at the top ends of the left catheter body and the right catheter body, and the left catheter body and the right catheter body are fixedly sleeved with tracheal cuff bodies located above the air outlet end of the left catheter body. A connecting pipe is fixed to the bottom end of the right catheter body through an angle adjusting assembly, and an air supply pipe is fixed to the tail end of the connecting pipe through a distance adjusting assembly. The bronchial catheter is novel in structure and ingenious in conception, the angle of the connecting pipe can be adjusted through the arranged angle adjusting assembly, so that the angle of the air supply pipe is adjusted, the problem that the opening direction of the right upper lung lobe varies can be solved, and the use requirements of different patients are met. Through the arranged distance adjusting assembly, the length of the air supply pipe can be adjusted, so that the position of the blue cuff is adjusted, and the problem that the distances between right upper lung lobe openings and tracheal carina of different patients are different can be solved.

Description

Technical field[0001]The present invention relates to the field of medical device, in particular a right double cavity bronchial conduit.Background technique[0002]Pulmonary isolation is a common respiratory management technique in thoracic surgery anesthesia. Specifically, the bronchial airway of the left and right lungs is applied to achieve selective single lung ventilation. The aim is to provide effective ventilation, airway protection against the aerial lungs, prevent blood, secretions, and cancerous tissue of the lungs, etc., causing adverse complications such as infection, diffusion and respiratory obstruction. In addition, single pulmonary ventilation can make the end of the lungs, thereby creating good articular fields, facilitating finding lesions and reducing damage to non-excessive lungs.[0003]There are many positional relationships between the patient's upper right pulmonary opening and the rhizosphere, resulting in the positioning of clinical and right double-cavity bro...

AI Technical Summary

Problems solved by technology

[0003] The positional relationship between the opening of the right upper lobe of the patient and the carina varies a lot, which makes it extremely difficult to locate the right double-lumen bronchial tube clinically, especially in female patients. Most of them are above the carina, which makes it difficult for the left lung to collapse satisfactorily due to the blockage of the blue cuff during right one-lung ventilation. In addition, the opening direction of the right upper lobe is mostly in the 3 o'clock direction, and the opening direction of some patients varies, which may At 6 o'clock, it may also be at 0 o'clock. Therefore, when positioning the right double-lumen bronchus catheter in such patients, the opening of the right upper lobe cannot be satisfactorily aligned, which will also lead to poor ventilation effect of the right lung
