摘要： A fluid trap for minimizing the escape of contaminated fluids from the fluid trap when an orientation of the fluid trap changes during removal or transport includes a front cover, a rear cover coupled to the front cover, and an interior chamber defined by the front and rear covers. The front cover defines an inlet port extending a first distance into an interior chamber of the fluid trap. The rear cover defines an exhaust port extending a second distance away from the rear cover of the fluid trap and positioned above the inlet port when the fluid trap is in an upright position. The interior chamber has a maximum fluid volume defined as the lesser of a fluid reservoir volume, a front cover volume, and a rear cover volume.

摘要： Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

摘要： A filter includes (i) a filter body, (ii) a front cap associated with a first end of the filter body and coupled to and receiving smoke from a vacuum hose, (iii) a back cap associated with a second end of the filter body and having a filter exhaust sized and shaped to associate with and communicate suction from a smoke evacuation system, (iv) a compressed carbon reservoir disposed within the filter body between the front cap and the back cap, and (v) a flexible porous barrier disposed on at least a first side of the compressed carbon reservoir. The compressed carbon reservoir is under a compressive bias by the flexible porous barrier that transitions from a flexed state to a partially relaxed state in response to the compressed carbon reservoir reducing in volume.

摘要： 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.

摘要： A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.

摘要： A smoke evacuation device that evacuates smoke from a surgical site and filters the smoke from the air. The smoke evacuation device can include a fluid trap for removing moisture from the smoke. The smoke evacuation device can also include a filter with a compression mechanism for compressing a filter medium. The smoke evacuation device can also include features for controlling flow parameters, noise, and vibrations of the device. A remote activation device can also be used to activate the smoke evacuation device upon detection of certain system parameters.

摘要： A filter connection for a smoke evacuation device includes a filter canister assembly and a socket. The filter canister assembly has a cross-sectional shape with only one line of symmetry that corresponds to a cross-sectional shape of the socket so that the filter canister can only be inserted into the socket in one orientation. One or more key notches on the filter canister may also ensure that the filter is properly installed. A seal creates an airtight boundary between the filter canister and a recess of the socket so that a sealed path in communication with the smoke evacuation device is established before the filter canister is fully inserted into the socket. An electronic connection is made between the filter canister and the socket after the airtight boundary is created.
