Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a mask for anesthesia. Background Art

[0002] Inhalation anesthesia is an anesthesia method in which anesthetics are inhaled through the respiratory tract, which produces central nervous system depression, causing the patient to temporarily lose consciousness and not feel pain all over the body. It is the main method of general anesthesia. The depth of anesthesia is related to the partial pressure of the drug in the brain tissue. When the anesthetic is excreted from the body or metabolized in the body, the patient gradually regains consciousness without any sequelae. Inhalation anesthesia is easy to control, relatively safe and effective, and is a commonly used method of anesthesia.

[0003] However, most of the current anesthesia masks have a fixed structure and cannot adapt to facial features. They may have gaps due to their poor fit to the face, especially for thin patients such as the elderly, whose cheeks will shrink. This area can only be sealed with temporary materials such as cotton wool, but the final sealing and stability will be poor. In order to improve the stability of the mask during surgery, the straps of the mask are generally tightened, which can easily cause discomfort to the patient. Therefore, how to provide a mask that can effectively seal the face and improve comfort is a problem that technical personnel in this field urgently need to solve. Utility Model Content
