Description

Gas anaesthetic mask

Technical Field

The invention relates to medical equipment, in particular to a gas anaesthetic mask.

Background

Anesthesia is a method used in various procedures during surgery or diagnostic examination operations for pain relief, patient safety, creation of good surgical conditions, and pain control. When performing surgery or diagnostic examination procedures, the patient may experience pain and need to be temporarily unconscious with narcotics or otherwise. Surgery or examination procedures can also cause mental stress and reflex adverse reactions, such as nausea, vomiting, caused by gastrointestinal surgery. Prolonged uncomfortable body positions (e.g., prone) can increase patient discomfort and pain. Therefore, patients should undergo surgery in a comfortable, quiet environment without responding to adverse stimuli and temporarily losing memory.

The existing anaesthetic mask has a simple and crude structure and is provided with an air bag, so that the anaesthetic mask is inconvenient to use, and meanwhile, the internal gas is filtered, but the consumption parts after filtering are inconvenient to disassemble, assemble and replace; meanwhile, the device has insufficient self-control flexibility, cannot reasonably convert oxygen and anesthetic gases, has poor anesthetic control precision, and is inconvenient to use because anesthetic gases are easy to leak due to the need of inserting tubes during anesthesia.
