Development and Application of a New Balloon Catheter for Intraairway Hemostasis

Massive hemoptysis is a serious disease of respiratory system, which seriously endangers the life of patients. There are obvious difficulties in the treatment of hemoptysis. In the traditional treatment, patients still have the risk of massive hemoptysis and suffocation, and the risk control in the treatment process cannot be ensured. Intra - airway interventional therapy, especially the hemostatic technique of intra - airway balloon catheter, is an important means to control the risk of hemoptysis. However, the current intraairway balloon catheter therapy technology is immature, complicated and difficult to operate, and the cost is high. There is a lack of special balloon for hemostasis, and the balloon borrowed for other purposes cannot meet the needs of hemoptysis treatment. Therefore, it is urgent to develop a new balloon catheter for airway hemostasis, which has simple technical operation, easy to master and popularize, efficient and safe function and structure. According to this requirement, this project designed and developed hemostatic balloon catheter with multiple functions such as self-guiding, anti-displacement, anti-leakage and detachable rear end, so as to make the treatment of massive hemoptysis more safe and effective, simpler and faster, so as to be widely applied in clinical practice.
