Abstract
A medical system can include a medical gas duct comprising a first end, a second end opposite the first end, a first opening at the first end of the duct, and a second opening at the second end of the duct. The first opening can be positioned to receive medical gas exiting an exhaust port of a medical gas evacuation unit. On the condition a medical suction supply provides a suction at the second opening of the duct, medical gas exiting the exhaust port of the medical gas evacuation unit flows into the first opening of the duct. Devices, systems, and methods relate to evacuating medical gasses.
Claims17
A medical system comprising:
- a medical gas duct comprising a first end, a second end opposite the first end, a first opening at the first end of the duct, and a second opening at the second end of the duct;
- wherein the first opening is positioned to receive medical gas exiting an exhaust port of a medical gas evacuation unit with a gap between the first end of the duct and the medical gas evacuation unit;
- and
- wherein in a state of a medical suction supply providing suction at the second opening of the duct, medical gas exiting the exhaust port of the medical gas evacuation unit flows into the first opening of the duct and ambient environmental air flows through the gap between the first end of the duct and the medical gas evacuation unit and into the first opening of the duct.
A system for exhausting gas used in a medical procedure, the system comprising:
- a medical gas evacuation unit and a duct;
- a tube configured to receive gas from a body cavity of a patient,
- wherein the medical gas evacuation unit comprises:
- a first vacuum source operably coupled to the tube,
- a particulate filter positioned to filter gas received from the tube, and
- an exhaust port positioned to vent gas received from the tube out of the medical gas evacuation unit;
- and
- wherein the duct comprises:
- an outlet configured to be removably coupled to a second vacuum source external to the medical gas evacuation unit, and
- an inlet positioned with a gap between the inlet and the exhaust port of the medical gas evacuation unit,
- wherein in a state of the outlet operably coupled to the second vacuum source, suction force through the duct draws gas away from the exhaust port and into the duct and ambient environmental air flows through the gap between the inlet of the duct and the medical gas evacuation unit and into the inlet of the duct.
A method of exhausting a gas from a patient, the method comprising:
- receiving, at a medical gas evacuation unit, gas from a body cavity of a patient in which a site of a medical procedure is located;
- exhausting the gas received at the medical gas evacuation unit from the body cavity through an exhaust port of the medical gas evacuation unit to an ambient environment external to the medical gas evacuation unit;
- and
- drawing, via medical suction supplied to a medical gas duct, the gas exhausting from the exhaust port of the medical gas evacuation unit into the medical gas duct through an opening spaced via a gap from the exhaust port,
- wherein during the drawing of the gas exhausting from the exhaust port of the medical gas evacuation unit, ambient environmental air flows into the opening of the medical gas duct through the gap.
