The technology disclosed herein relates to a filter element having a first endcap, a second endcap, and filter media extending between the first endcap and the second endcap. The filter media defines a central opening and is coupled to the first endcap and the second endcap. A filter cover is coupled to the first endcap, and a breather filter is integral to the filter cover. The breather filter defines a first flow face and a second flow face. The filter element defines an airflow pathway from ambient environment through the first flow face and the second flow face.

A gas conditioning unit for a surgical gas delivery device is disclosed, which includes a filter housing having an insufflation gas flow path for delivering insufflation gas to a body cavity and for facilitating pressure measurements from the body cavity, a pressurized gas flow path for delivering pressurized gas from a pump in the surgical gas delivery device to an internal nozzle in the filter housing that accelerates the pressurized gas and thereby generates a continuous pressure barrier that inhibits egress of insufflation gas from the body cavity, a vacuum return flow path for returning depressurized gas spent by the internal nozzle back to the pump under vacuum, an air entrainment flow path for drawing air into the body cavity to maintain a given pressure therein, and a smoke evacuation flow path for conveying smoke from the body cavity.

The present invention discloses a rectangular shaped filter and coalescer elements and a vessel that houses a plurality of such rectangular shaped elements. Greater filtration or separation efficiency is provided due to increased number and alignment of rectangular shaped filter elements in the vessel. The rectangular shaped filter elements are also easy to replace.

The invention relates to a filter arrangement for cleaning an air stream having at least three filter elements, wherein each filter element has a bellows made of pleated filter medium, wherein the filter elements are arranged in series and any two adjacent filter elements are connected to one another by means of a connecting tab. According to the invention, a fold run-out of all end folds of all bellows is oriented in a particular direction, the connecting tabs are of two different embodiments and the different embodiments of the connecting tabs are arranged alternatingly when viewed in a longitudinal direction of the filter arrangement. Not only is a simple installation of the filter elements in a filter holder thus facilitated but also a defined seating of the filter elements in the filter holder is ensured.

An all-in-one, universal bacteria filter apparatus which (i) can be used with oxygen concentrators produced by numerous different manufactures, (ii) can be used with concentrators of different capacities, and (ii) can be use in both vertical and horizontal orientations.

An air filter apparatus is provided. The air filter apparatus includes a manifold having at least one compressible gas inlet and an outlet. The internal volume of the manifold increases from a distal end of the manifold to the outlet. A shroud is detachably mounted to the manifold so that a compressible gas can enter the shroud and pass through the at least one compressible gas inlet and through the outlet.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

A filter cartridge for surgical gas delivery systems includes a filter housing configured to be seated in a filter cartridge interface of a surgical gas delivery system. A first filter element is seated in a first end portion of the filter housing. A second filter element is seated in a second end portion of the filter housing opposite the first end portion. A third filter element is seated in the filter housing between the first and second filter elements. The third filter element can include an activated carbon material, such as an activated carbon disc.

A surgical gas delivery device includes a filter cartridge interface and a computer controlled control unit configured to control the circulation of surgical gas during endoscopic surgery. The control unit can operate in a plurality of different modes of operation. A tube set for connecting the surgical gas delivery device to one or more end effectors includes a filter cartridge in fluid communication with the tube set. The filter cartridge is seated in the filter cartridge interface of the surgical gas delivery device to communicate surgical gas between the surgical gas delivery device and the one or more end effectors. The surgical gas delivery device includes a reader operatively connected to receive input from a data carrying element of the tube set. The data carrying element, reader, and control unit can launch a specific one of the modes of operation when the filter cartridge is inserted.

A purification device for disinfecting and filtering intake air is disclosed. The purification device comprises a housing provided with a number of inlet perforations for allowing the intake air to enter the housing and a number of air outlet perforations for allowing air purified by the purification device to leave the housing. The purification device moreover comprises a fan arranged inside the housing to suck the intake air into the housing and blow the purified air out of the housing. The purification device further comprises an ultraviolet radiation lamp arranged inside the housing to irradiate the intake air. The purification device also comprises a high-efficiency particulate air (HEPA) filter arranged to filter the intake air before the intake air leaves the housing as purified air. The filter comprises a plurality of pleats arranged in such a manner that the angle between adjacent pleats is 30 degrees or less.
