A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

Wound retractor and diffuser

This invention relates to a surgical smoke evacuation system for use in removing gases and smoke created in surgical procedures form within an insufflated surgical cavity. Such a system comprises a discharge assembly adapted to form a gases path, and having an end which in use is located within said surgical cavity so that gases and/or surgical smoke inside said cavity can pass out of said cavity and through said discharge assembly along said gases path, a flexible discharge limb having an operational site end and an outlet end, and a self-supporting wall defining a gases flow passage between said operational site end and said outlet end, in use said open operational site end sealingly connected to said discharge assembly so that said gases and/or surgical smoke can pass out of said discharge assembly and into said discharge limb, a filter connected in use to the outlet end of the discharge limb, at least part of said wall of the discharge limb formed from a breathable material, said breathable material allowing the passage of water vapour through the wall of the discharge limb without allowing the passage of liquid water or surgical smoke or other gases.

This invention relates to apparatus used to alter the temperature and humidity of gases. The apparatus of the present invention comprises an insufflator, humidifier and transportation means connected to delivery means to deliver humidified and heated gases to a body cavity prior to and during a medical procedure. In one form of the present invention the insufflator and humidifier are contained in the one housing, while in another form the humidifier is located proximal and external to the insufflator. The transportation means that delivers the humidified gases to the body cavity comprises a flexible tubing having located within, throughout or around it heating means. The heating means may be a heat conductive wire, a ribbon of PTC material, or a conducting wire extruded into the walls of tubing, where the tubing may be made from a PTC material or flexible plastics.

Apparatus used for the humidification of gases in medical procedures

An active smoke filtration unit is used to remove smoke during laparoscopic surgery. The active smoke filtration unit is part of a recirculation circuit. The recirculation circuit is pneumatically isolated from a primary flow generator, such as an insufflator, by a valve assembly. The active smoke filtration unit can be housed separately from the valve assembly or together with the valve assembly. The recirculation circuit can include a humidifier to heat and humidify the insufflation gases.

This invention relates to apparatus used to heat, humidify and filter insufflated gases to alter the temperature and humidity of gases prior to delivering the gases into a patient The apparatus includes an insufflator, humidifier and gas transportation conduit connected to gas delivery tubing to deliver humidified and heated gases to a body cavity prior to and during a medical procedure. The insufflator an humidifier are contained in the one housing, enabling the housing to be located remote from an operating table. The gas transportation conduit delivers the humidified gases to the body cavity in a flexible tubing having located within, throughout or around it heating apparatus enabling the gas temperature and humidity levels to be maintained from the housing to the patient.

A filter for a respiratory circuit has a housing with an inlet port and an outlet port for connection to respective breathing tubes. A gases space lies between the inlet and outlet ports and gases pass across the gases space from the inlet port to the outlet port in use. A filter media spans the gases space, dividing the gases space into an inlet chamber and an outlet chamber. Gases passing from the inlet port to the outlet port pass through the filter media. A surrounding outer wall surrounds the housing apart from the inlet port and outlet port and is spaced from the wall of the housing. One or more air pockets are created between the outer wall and the housing. The air pockets insulate the housing from ambient conditions.
