Abstract
A smoke evacuation device includes one or more cooling mechanisms and an exhaust mechanism to reduce velocity and noise of filtered air exiting the smoke evacuation system. The cooling mechanism includes ventilation openings and/or a rotary mechanism disposed within the system to circulate air and cool by convective heat transfer. A pressure relief mechanism is also provided at the inlet or outlet of the system or the pump within the system. The pressure relief mechanism is configured to reduce pressures due to abnormal flows within the smoke evacuation system.
Claims20
A smoke evacuation system, comprising:
- a housing at least partially surrounding an enclosure;
- an airflow path extending inside the enclosure from an inlet port to an outlet port of the smoke evacuation system;
- a motor disposed inside the enclosure and having a work output;
- a pump disposed inside the enclosure;
- and
- a cooling mechanism configured to induce airflow through the enclosure to cool the enclosure, the induced airflow being proportional to the work output of the motor.
A smoke evacuation system, comprising:
- an inlet port;
- an outlet port;
- an airflow path extending between the inlet port and the outlet port;
- a housing at least partially surrounding an enclosure;
- and
- an exhaust mechanism near the outlet port and configured to diffuse air exiting at the outlet port to reduce exit noise without baffling or redirecting flow causing an exit head pressure.
A smoke evacuation system, comprising:
- an inlet port;
- an outlet port;
- an airflow path extending between the inlet port and the outlet port;
- and
- one or more pressure release mechanisms configured to regulate a pressure inside the airflow path.
