Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a laryngeal anesthesia sprayer for anesthesiology. Background Art

[0002] When the hospital performs throat examinations, indirect laryngoscopy, fiberoptic laryngoscopy and other operations on patients, the patient's pharynx and larynx must be anesthetized before the operation. The throat spray method is widely used in throat surgery and endoscopic examinations. It is mainly used for mucosal surface anesthesia to ensure that patients with sensitive throat reflexes can cooperate and complete the examination. The throat spray method is used for local anti-inflammatory, analgesic, astringent, moisturizing and anesthesia of the throat. In modern medicine, many throat surgeries require anesthesia of the throat. Laryngeal anesthesia is difficult and has high anesthesia requirements. If adequate anesthesia cannot be performed, it will easily affect the surgical effect.

[0003] Existing laryngeal anesthesia sprayers have many parts, are difficult to operate, and have poor anesthesia effects. Patients often open their mouths for a long time during anesthesia, which makes it easy for them to bite the medicine tube, affecting the anesthesia effect. In addition, general anesthesia sprayers are inconvenient to configure medicines. Utility Model Content
