Description

Technical Field

[0001] The invention relates to the field of anesthesia, in particular to an anesthesia device based on laryngoscope. Background Art

[0002] In the medical field, laryngoscopes play an extremely important role in oral examinations, treatments and surgeries. They can provide doctors with a clear field of vision, help them perform precise and effective operations, and improve patients' comfort to a certain extent. However, in the current practical application of multifunctional laryngoscopes, there are some problems that need to be solved.

[0003] When using a multifunctional laryngoscope, its position is prone to shifting, which undoubtedly adds difficulty and uncertainty to the operation. What is even more difficult is that during the spraying of local anesthetics, since there is often sputum in the patient's throat, this situation has many adverse effects on the anesthetic effect. When sputum is present in the throat, it will dilute the anesthetic and form a barrier between the throat wall and the anesthetic, greatly weakening the effect of the anesthetic directly acting on the throat wall. In addition, the presence of sputum also seriously interferes with the doctor's accurate calculation of the amount of anesthetic sprayed. Because when spraying anesthetics, anesthetics can easily adhere to sputum, and in the subsequent process of clearing sputum, the anesthetics that have been attached to the sputum will be removed together, making it difficult for the anesthetic to form an effective concentration distribution on the throat wall, thereby affecting the overall effect and quality of anesthesia, and increasing the risks and uncontrollable factors during surgery or examination.
