Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies and relates to a visual operation device and method for preventing environmental pollution during tracheal intubation. Background Art

[0002] Tracheal or esophageal intubation is a common rescue treatment for critically ill patients. During the operation, the epiglottis is stimulated. The laryngoscope blade stimulates the epiglottis, and the patient is prone to choking and coughing, causing the gas or secretions in the airway to be coughed out, or nausea and vomiting, vomiting out the gastric contents. At this time, an assistant is required to use an aspirator to attract the secretions or gastric contents at any time. For patients with respiratory tract infections or infectious diseases, such as pneumonia caused by the new coronavirus, the gas exhaled or coughed by the patient contains a large amount of viral aerosols, which is an important way for medical staff to be infected. The intubation process is extremely risky for both the patient and the doctor who performs the operation. On the one hand, it is necessary to prevent foreign objects from slipping into the airway and causing suffocation; when the epiglottis is lifted, respiratory and cardiac arrest may also occur due to the vagus nerve reflex. In addition, at the moment of intubation, the droplets sprayed from the patient's lower respiratory tract have a very high viral load. Even if the medical staff on the scene take strict precautions, the possibility of infection is still very high due to face-to-face close contact. Even if protective gear is worn, the gas exhaled or coughed by the patient may cause environmental pollution. Once the protective gear of medical staff is damaged, it is easy to cause infection. Tracheal intubation and gastric tube placement for COVID-19 are both extremely risky operations. Existing protective gear, medical closed respirators and other protective equipment can only be used for medical staff. Currently, commonly used protective equipment are goggles and face shields. When wearing protective clothing, N95 masks, etc., it is very easy for goggles or face shields to fog up and the field of vision to be unclear. The longer the medical staff stay in the isolation ward, the more likely this will happen. Summary of the invention
