Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a device for recovering and discharging anesthesia ether waste gas. Background technique

[0002] Anesthetic drug delivery systems in surgical settings (medical, dental, and veterinary) generate large amounts of waste anesthetic gas. Exhaled air from patients is currently collected by dedicated or shared vacuum systems. Healthcare facilities typically employ one or more central vacuum pumps to collect exhaust air from individual anesthesia locations. These vacuum pumps are generally oversized, so they are designed to collect exhaled anesthetic gases over a wide range of flow rates. Because these pumps run continuously, the waste anesthetic gas aspiration system also draws large amounts of ambient room air from the anesthesia site, diluting the waste anesthetic gas significantly. In central vacuum pumps, the airflow is often mixed with other room air to further dilute i...
