Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visual supraglottic oxygen inhalation weak stimulation oropharyngeal airway device. Background Art

[0002] The oropharyngeal airway is a non-invasive ventilation tube that is not a tracheal tube. It is mainly used to prevent tongue retraction, quickly open the airway, and establish a temporary artificial airway. Doctors and nurses in clinical departments such as anesthesiology, respiratory medicine, ICU, and emergency department often use it as an auxiliary device for airway management. With the promotion and implementation of comfortable medical care, non-endotracheal intubation intravenous anesthesia is widely used in clinical practice, such as painless gastroenteroscopy, fiberoptic bronchoscopy, abortion, short and minor surgery, etc. Respiratory depression and airway obstruction caused by intravenous anesthetics often cause hypoxemia, which can cause respiratory and cardiac arrest in severe cases.

[0003] At present, the oropharyngeal airways widely used in clinical practice generally have some disadvantages:

[0004] 1. When the patient's anesthesia depth becomes shallower, the throat reflex of the inserted oropharyngeal airway is stronger, which will cause strong nausea, vomiting and even laryngeal spasm.

[0005] 2. After being given intravenous anesthetic drugs, patients will generally experience respiratory depression. Doctors will usually make a judgment based on the decrease in oxygen saturation values, but this is lagging and it is impossible to dynamically observe the changes in the patient's glottis closure amplitude in real time to judge the patient's degree of respiratory depression.

[0006] 3. The oropharyngeal airway commonly used in clinical practice cannot provide supraglottic oxygen inhalation, and oxygen is usually given through the nose. The patient's nasal secretions and tongue root retraction will affect oxygen inhalation.

[0007] To this end, the utility model proposes a visual supraglottic oxygen inhalation weak stimulation oropharyngeal airway device. Utility Model Content
