Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for efficiently extracting anesthetic waste gas. Background Art

[0002] When performing surgery on a patient, anesthetics are generally used. In the prior art, anesthetics are mostly introduced into the patient's body by atomization inhalation. However, during the process of delivering the atomized anesthetic to the patient, part of the anesthetic mist escapes from the gap of the breathing mask due to the patient's exhalation, and diffuses throughout the operating room, which is bound to cause air pollution in the operating room environment. Long-term exposure to this trace amount of anesthetic waste gas pollution can have an adverse effect on the physical and mental health of operating room staff. Relevant animal experiments and studies have shown that long-term exposure to anesthetic drugs may cause short-term damage and potential long-term damage, posing a threat to the health of medical staff. Anesthetic waste gas pollution in operating rooms and its hazards have attracted widespread attention. Reducing anesthetic waste gas pollution in operating rooms and strengthening the health protection of staff have become important aspects of operating room environmental protection.

Both of them use filtering, adsorption and disinfection of waste gas, but cannot catalyze and wash the waste gas, resulting in incomplete waste gas treatment. The discharge of untreated waste gas will have an impact on the environment. Utility Model Content
