Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of medical apparatus and instruments, and particularly relates to a disposable anesthetic waste gas adsorber. BACKGROUND

[0002] With the rapid progress of medical science and technology, more and more new anesthetics have been developed and applied in clinical practice, greatly improving the safety and efficiency of general anesthesia surgery. However, this has also brought an issue that cannot be ignored - anesthetic waste gas pollution in the operating room. These waste gases are continuously generated during surgery and diffuse in the operating room air, posing a serious threat to the health of operating room staff. Numerous animal experiments have confirmed that long-term exposure to anesthetic waste gas environment can cause damage to the reproductive system and hematopoietic system, leading to health problems such as miscarriage and bone marrow suppression. At the same time, epidemiological investigations and clinical observations have found that the incidence of malignant tumors among operating room staff is significantly higher than that among non-operating room staff. These problems not only affect the quality of life of operating room staff, but also bring additional medical burden and loss of human resources to medical institutions. Therefore, anesthetic waste gas pollution in the operating room has become an important problem that needs to be solved. Medical institutions and relevant departments need to take effective measures to strengthen the emission control and protection of anesthetic waste gas to ensure the health and safety of operating room staff.

The anesthetic waste gas adsorber designed in the utility model has the characteristics of small size, simple structure, convenient installation and use, good performance, and low production cost. It uses adsorption medium with high adsorption rate and a clever and simple rotary structure to fully adsorb the anesthetic waste gas discharged by the anesthetic machine during surgery, prevents the escape of anesthetic waste gas from the source of pollution, ensures the health of operating room staff, and is suitable for use in various general anesthesia operating rooms.
