A manifold assembly for a surgical gas delivery system is disclosed, which includes a manifold body including an inlet port for receiving gas from an outlet side of a compressor and an outlet port for recirculating gas to an inlet side of the compressor, a bypass valve communicating with the inlet port and the outlet port of the manifold body, an air ventilation valve for dynamically controlling the ingress of air from atmosphere, a smoke evacuation valve for dynamically controlling the egress of gas from the manifold assembly when the gas delivery system is operating in a smoke evacuation mode, and a gas fill for dynamically controlling the receipt of gas from a source of surgical gas.

A gas heater for a surgical gas delivery system is disclosed, which includes an elongated tubular body defining an interior flow passage having an inlet port for receiving insufflation gas from a gas source and an outlet port for delivering heated insufflation gas to an insufflation manifold, a dielectric support positioned within the interior flow passage of the tubular body, and a resistive element operatively associated with the dielectric support for heating insufflation gas flowing through the tubular body from the inlet port to the outlet port.

A breathing treatment apparatus delivers breathing gas to a user. The apparatus may be configured to comprise one or more sensors for sensing microbial growth within the apparatus.

An instrument includes a handle assembly, a shaft, a dilation catheter, and a position sensor. The shaft extends distally from the handle assembly. The shaft includes a distal end that is configured to be introduced into an anatomical passageway within a head of a human. The dilation catheter includes an expandable dilator and is configured to advance distally relative to the shaft. The position sensor is configured to generate signals indicating a position of the position sensor within the head. The position sensor is configured to advance distally between at least first and second positions. The position sensor is disposed adjacent the distal end of the shaft in the first position, and is configured to be carried further distally by the dilation catheter to the second position. In the second position, the position sensor is separated a distance from the distal end of the shaft.

Technologies for sanitizing medical devices are described. In particular, sanitizing systems, components of sanitizing systems, and methods for sanitizing medical devices such as continuous positive airway pressure (CPAP) equipment are described. In embodiments, the sanitizing systems include a sanitizing gas generator and a base including at least one exhaust port and a filter.

A gas delivery system (50) for delivering a flow of breathing gas to a patient (54) includes a blower assembly (100) structured to generate the flow of breathing gas. The blower assembly includes a gas flow path including an inlet manifold, an assembly (130) structured to adjust a pressure and/or flow rate of the flow of breathing gas, and an outlet manifold structured to be coupled to a patient circuit. The gas delivery system additionally includes a light system structured to generate sanitizing light and deliver the sanitizing light to one or more internal surfaces of at least one of the inlet manifold, the assembly and the outlet manifold for sanitizing the one or more internal surfaces.

Disclosed herein is a molecular imprinted protective face mask comprising a supportive structure, a surface material that receives and retains a molecular imprint and that is positioned to contact airborne molecules during use, a molecular imprint of a bioactive molecule wherein an imprinted cavity is at least one of a bioactive molecule with a molecular configuration that captures a specific airborne and/or microdroplet-borne molecule and a protein with a binding site that captures a specific molecule.

A declogging assembly (20) is configured for use with a suction conduit (10). The suction conduit has a head (14) at a first end (15) and a vacuum tube connection (16) at a second end (17). The assembly includes a body (30). The body defines a first aperture (32), a second aperture (34), and a third aperture (36). The assembly also includes a plug (40) disposed within the body (30). The plug has a surface (42) configured to contact the head (14) of the suction conduit (10) so as to move the plug from a first position, in which the first aperture (32) is in fluid communication with the second aperture (34), to a second position, in which the first aperture (32) is in fluid communication with the third aperture (36). The assembly (20) also includes a biasing member (50) configured to bias the plug into the first position.

A device for minimizing obstruction in a medical device that carries fluids includes a housing defining a channel configured to receive and secure a section of the medical device such that the section of the medical device extends coaxially with a central longitudinal axis of the channel. The device also includes components supported in the housing, including a motor, wherein the components are configured to be operated to impart motion to the housing and the attached medical device. The motion is configured to produce oscillatory motion of a frequency sufficient to concentrate shear stresses in a fluid boundary layer adjacent an inner wall of the medical device. The housing and the components supported in the housing are configured and arranged so that a device center of mass lies along or near the longitudinal axis of the channel.

The present specification, in some embodiments, describes a personal wear device that direct the flow of air away from a person's face, reducing or blocking the flow of infectious pathogens towards a patient's naso-oral area thus reducing the risk of inhalation of infectious or noxious pathogens. In another embodiment, the present specification describes a personal air management mask system for use by a patient for reducing or preventing exposure to and inhalation of infected aerosol during a medical procedure.
