Surgical smoke scavenging device

By introducing a combination structure of sedimentation tank and purification chamber into the surgical smoke purification device, particulate matter is settled using sedimentation liquid and defoaming net, and multi-stage purification is carried out in the purification chamber. This solves the problem of incomplete particulate matter purification in existing devices and achieves a more efficient smoke purification effect.

AI Technical Summary

Technical Problem

Existing surgical smoke purification devices are ineffective at purifying particulate matter in the smoke, and the particulate matter can easily be directly discharged into the outside environment with the airflow, posing a safety hazard.

Method used

It adopts a combination structure of sedimentation tank and purification chamber. The sedimentation tank is equipped with sedimentation liquid and defoaming net. The sedimentation liquid settles and dissolves particulate matter in the smoke. The purification chamber is equipped with activated carbon area and disinfection area to carry out multi-stage purification of smoke.

Benefits of technology

It effectively settles and separates particulate matter in smoke, reduces the residue of harmful substances, significantly improves the purification effect, and ensures the safety of smoke discharge.

Abstract

This utility model provides a surgical smoke purification device, including an exhaust pipe, a smoke pump body, a settling tank, and a purification chamber disposed on the exhaust pipe. The two ends of the exhaust pipe are an air inlet and an air outlet, respectively. The smoke pump body, the settling tank, and the purification chamber are arranged along the direction from the air inlet to the air outlet. The settling tank contains a settling liquid and an antifoaming net immersed in the settling liquid. The bottom of the settling tank is connected to the smoke pump body, and the top of the settling tank is connected to the purification chamber. This device can settle particulate matter in the smoke, effectively improving the purification effect.
