Description

Technical Field

[0001] The utility model relates to a general anesthesia endotracheal cannula, in particular to a disposable general anesthesia endotracheal cannula. Background Art

[0002] General anesthesia can be divided into intravenous general anesthesia and endotracheal intubation general anesthesia. Different surgeries have different requirements for anesthesia. Generally, during surgery, most general anesthesia requires endotracheal intubation. Some long-term surgeries, such as brain tumor resection in neurosurgery, valve replacement in cardiac surgery, radical resection of esophageal cancer in tumor surgery, or lower abdominal and lower limb surgeries for patients with contraindications to spinal anesthesia, or some patients who are restless and unwilling to cooperate with anesthesia surgery, need to be under endotracheal intubation general anesthesia to complete the surgery. Therefore, endotracheal intubation general anesthesia is something that anesthesiologists must master.

[0003] As disclosed in the authorization announcement number CN111359070B, a general anesthesia endotracheal intubation tube is disclosed, and the key points of its technical solution are: it includes an insertion tube, one end of the insertion tube is fixed with a first threaded joint, the other end of the insertion tube has a penetration tube portion integrally formed with the insertion tube, the penetration tube portion has a taper, a groove-shaped air port is opened on the penetration tube portion, a plurality of circular air ports are opened on the insertion tube, and an end air port is opened at the end of the penetration tube portion, a top support airbag and a protective airbag are fixed on the outside of the insertion tube, and a sputum suction component for sucking sputum and an inflation component for simultaneously inflating the top support airbag and the protective airbag are also provided on the insertion tube; during the insertion process, the general anesthesia endotracheal intubation tube is not easy to puncture the airway, can reduce complications, ensure the smoothness of the airway and can reduce the difficulty of extubation, but it is inconvenient to clean the inside during use and has a high manufacturing cost. For this reason, we propose a disposable general anesthesia endotracheal intubation tube to solve the problems of inconvenient internal cleaning and high manufacturing cost of traditional equipment.
