Description

Cannula assembly for trachea Technical Field The application relates to the technical field of medical equipment, in particular to a sleeve assembly for an air pipe. Background Currently, patients who receive tracheotomy after laryngeal carcinoma surgery or due to tracheal invasion need to wear tracheal tubes for a long period of time to maintain the airway unobstructed, however, the existing products have obvious disadvantages. If the traditional metal sleeve is not provided with a cuff and the laryngeal operation region suddenly bleeds after operation, blood can directly flow into the lung along the tracheostomy, so that airway obstruction, dyspnea and even asphyxia are caused. Moreover, during rescue, blood may have invaded the lower respiratory tract, leading to increased difficulty in treatment and increased mortality. At the same time, metal cannulas can interfere with CT and magnetic resonance examinations, requiring temporary extubation by the patient, which can increase airway risk. However, existing cannula assemblies often employ a single design of "sleeved inner core-less" or "sleeved inner core-less". The sleeve with the cuff and without the inner core is easy to adhere to the inner wall, sputum and blood scab are required to be pulled out integrally during cleaning, the operation risk is high, the sleeve with the inner core and without the cuff cannot prevent bleeding in an operation area from flowing to the lung, and the choking hidden trouble still exists. In summary, the existing products are difficult to meet multiple requirements of postoperative emergency hemostasis, daily anti-blocking and the like.
