A system for retrieving material from a cavity in a patient may include a tube having a proximal end and a distal end, the scope configured to be inserted into the cavity, and a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause the material to flow through the tube from the distal end to the proximal end, the filter assembly including a filter configured to trap the material in the filter assembly, and allow liquid and gases to pass through the filter assembly.

A filter assembly for use with a surgical suction tool for removing fluid and debris from a surgical site includes a conical filter element with a plurality of orifice arrays spaced along the length of the conical body with successively decreasing orifice diameters. The filter element includes an annular flange at the mouth of the filter element that is clamped between a container and a cap. The container includes conically tapered wall to define a radial space between the container and the filter element to permit fluid flow around the filter element and through the container to an outlet tube fitting. A cap covers the mouth of the container with a threaded interface defined between the cap and the container. The threaded interface includes a dual pitch triple lead thread with a coarse lead-in pitch and a fine trailing pitch.

A handling bar for laminated or film supports, such as paper, is disclosed, including a hollow tubular body provided with an inner cavity and an outer side surface, a plurality of through holes, arranged on the tubular body to put the inner cavity in contact with the outer side surface. The handling bar also includes at least one connection to a compressed air source or a suction device, where the connection is shaped for the inflow of compressed air or to suction air into the cavity and at least one filtering element arranged inside the tubular body where at least at one portion of the holes filters the air passing between the inner cavity and the holes.

A filter cartridge assembly is disclosed, which includes a housing having a reservoir for collecting fluids entering the housing through a gas return path, a sensor located within the reservoir for detecting a fluid level therein, and a backer plate positioned within the housing adjacent an inlet port to the reservoir and including fluid management structure to shield the sensor from fluid entering the reservoir from the gas return path through the inlet port and causing a false indication of the fluid level in the reservoir.

An outer wrapper that defines a top wall, a bottom wall, a rear wall, and first and second side walls and includes an inner liner. A trim breaker seals the outer wrapper to the inner liner to define an insulation space. A single vacuum port is disposed on each of the top wall, the bottom wall, and the first and second side walls. A plurality of vacuum ports is disposed on the rear wall. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed proximate each vacuum port such that air can be drawn from the insulation space past the filter media and through each vacuum port.

A facepiece charging device comprising a receptacle system, an electrostatic charging system, and a support structure. The receptacle system is configured to detachably receive and secure a facepiece. The electrostatic charging system is configured to transfer an electrostatic charge to the facepiece when energized. The support structure has a moveable guide system coupled to at least one of the receptacle system or the electrostatic charging system. The moveable guide system has at least an engaged position where the receptacle system is adjacent the electrostatic charging system to electrostatically charge the facepiece and a disengaged position where the receptacle system is spaced from the electrostatic charging system.

The present disclosure provides an exhaust module for exhausting an exhaust from at least one wafer baking apparatus having an exhaust port. The exhaust module includes at least one pipeline, a heating unit, a solvent dispensing unit, and a filtering unit. The at least one pipeline is connected to the exhaust port of the wafer baking apparatus and configured to exhaust the exhaust gas from the wafer baking apparatus. The heating unit is connected to the pipeline and configured to heat the exhaust gas. The solvent dispensing unit is connected to the heating unit and configured to dispense a solvent to cool and dissolve the exhaust gas. The filtering unit is connected to the solvent dispensing unit and configured to filter the solvent.

The solar-powered oxygen production system for hospitals is useful for producing oxygen in hospital settings without the need for an external power source. The system includes one or more photovoltaic (PV) solar panels mounted on the roof of a hospital and an oxygen production system housed within the equipment room of the hospital. The solar panels provide the electrical power needed for the oxygen production system. The solar panels are mounted on the roof using solar panel supports. The number of panels and the power output of each panel can be selected depending on the electrical power requirements of the oxygen production system. The oxygen production system includes an LED for activating a black phosphorous catalyst in the atmospheric air to convert water vapor in the air into hydrogen and oxygen.
