Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pre - hospital emergency equipment, and particularly relates to a device for sucking foreign bodies in the respiratory tract for pre - hospital emergency. Background Technique
[0002] Foreign bodies in the respiratory tract can stimulate the respiratory mucosa, causing symptoms such as coughing and difficulty in breathing. If foreign bodies remain in the respiratory tract for a long time, it may also lead to complications such as inflammation and infection, and in severe cases, even death. Therefore, once a foreign body blocks the respiratory tract, immediate measures should be taken to remove the foreign body to avoid more serious consequences.
[0003] During emergency first aid and 120 pre - hospital emergency, patients with foreign body obstruction in the respiratory tract are often encountered. Some healthy patients who can stand are suitable for the Heimlich maneuver, but some elderly and weak patients, patients with cerebral infarction and other diseases (such as rib fractures, lower limb fractures, etc.) cannot stand and cannot use the Heimlich maneuver. There are also some patients who have just had abdominal surgery and have various drainage tubes in the abdomen, and they cannot use the Heimlich maneuver either. For bedridden patients with hypostatic pneumonia, expectoration may occur, and asphyxia is likely to occur. In view of this, there is an urgent need to design a device that can replace the Heimlich maneuver and facilitate the rapid removal of foreign bodies in the respiratory tract of patients.
