[0002] Anesthesia reservoirs are medical devices that are usually used to provide the anesthetic drug and gas mixture that patients need during surgery. It is a bag-like structure, usually made of elastic material, that can shrink and expand to adapt to needs. The reservoir usually consists of an air inlet and an air outlet, through which the anesthesiologist can inject the anesthetic drug and gas mixture into the reservoir, and then control the release of the drug through the air outlet. Anesthesia reservoirs come in many different shapes and models, and each type is suitable for different anesthesia applications. It can be used alone or in conjunction with other medical devices and operating room equipment to ensure that patient pain and discomfort are minimized during surgery, helping to improve the success rate of surgery and the speed of patient recovery.
