Universally adaptable evacuators are adaptable to all surgical fields, easy to apply and, in most cases, may be expanded and / or removed as necessary. A hollow tube including a fitting adapted for connection to a vacuum source and at least one smoke inlet is held in position with the smoke inlet proximate to a surgical wound. According to a preferred embodiment, a stapling tab extending from a flexible perforated tube is used to hold the evacuator in place around the periphery of a surgical incision. According to an alternative embodiment, a smoke evacuator attaches temporarily or permanently to a retractor or other surgical instrument. Standard tubing and couplers may be used and the assembly may be prepackaged in sterile condition and disposed after use.

The invention relates to the technical field of fire-fighting, in particular to a control system and method of smoke-removing fireproof fire-fighting staircase. The staircase comprises upper stairs, lower stairs, a wall and a fireproof door, wherein the wall is coated with fireproof layers, and a fire hydrant is arranged on the wall and located above a platform; and the input end of a controller is connected with a smoke alarm, the smoke alarm is arranged on the wall and used for detecting the concentration of smoke in the staircase, and the controller is connected with a smoke exhauster whichis used for exhausting smoke in the staircase. When a fire disaster occurs, people can escape to the staircase for escape, and the fireproof door and the fireproof wall can effectively prevent further spreading of the fire behavior; and when the smoke alarm in the staircase detects that the concentration of the smoke in the staircase exceeds a set value, the smoke alarm sends a signal to the controller and gives an alarm, and meanwhile, the controller controls the smoke exhauster to be started to exhaust the smoke out of the staircase so that the situation that air cannot circulate due to much smoke in the staircase can be avoided, and it can be effectively guaranteed that people can escape safely.

An automatic smoke evacuation and insufflation system for surgical procedures having a vacuum for removing gas, smoke, and debris from a surgical site and an insufflator for supplying gas to the body cavity of a patient.

The invention relates to a three-nozzle offset inclination angle induced air smoke evacuator, which consists of a fan, an air outlet pipe, three offset inclination angle jetting heads, a flue and a kiln tail gas inlet, wherein the three jetting heads are positioned in a way of forming included angles of 120 degrees with one another, incline at obtuse angles relative to a horizontal plane, and are positioned close to the side of the flue. Pressurized air is obliquely jetted and induced into the flue at a high speed by using the high-pressure fan via the three offset jetting heads to form a negative pressure, and three branches of high-speed air flow are mixed with flue gas in the flue to form spiral rising air flow, so that the blocking effect of a pneumatic turbulent area formed on the lower-middle part of the flue is eliminated basically, non-contact smoke evacuation is realized, a rapid, efficient, low-consumption and energy-saving smoke evacuation effect is achieved, and stable running of a kiln is ensured.

A surgical drape plume evacuator includes a filter enclosure. An operating aperture disposed in the filter enclosure defines an area within the filter enclosure. A pressure source for creating at least one of a negative and positive air pressure in the filter enclosure. A fluid opening in the operating aperture connects the interior of the operating aperture to the interior of the filter enclosure.

A docking system for electrosurgical equipment where a first docking interface is a recess in the housing of a smoke evacuator and a second docking interface is a raised portion of an electrosurgical unit.
