Insufflation circuit and filter

Disclosed herein is a surgical cannula configured as an instrument retaining or centering apparatus, configured for providing insufflation gases to a surgical cavity of a patient (such as the pneumoperitoneum) and allowing insertion of medical instruments into the surgical cavity through the cannula. The cannula can include features to direct gas flow in particular directions to prevent or reduce smoke, fog/condensation, or other unwanted media from contacting a portion of a medical instrument.

Connector for insufflation circuit

A patient interface can have a frame supporting a sealing member. Various features of the sealing member can improve comfort and sealing performance in the context of forming seals with the nares of a user, as well as contact with other facial surfaces. The sealing member can include convex portions, concave portions and thickness variations for providing various sealing, comfort, and deformability effects.

Patient interface and aspects thereof

A humidification system has a tube configured to transport gases. The tube is configured to be soaked prior to use and has a bead to hold liquid. Heat applied to the bead causes the liquid to be released as vapour. Gases flowing through the tube are heated and humidified by the vapour.

System for humidification of medical gases

A humidifier for delivering humidified gases to a patient includes an inlet, an outlet, a gases flow path extending from the inlet to the outlet, a permeable wall, a liquid reservoir, and a heater. The permeable wall separates the gases flow path from the liquid reservoir. The heater heats liquid stored in the liquid reservoir to form vapour, and the vapour passes through the permeable wall to the gases flow path to humidify gases in the gases flow path. Another inline humidifier for delivering humidified gases to a patient includes an inlet and an outlet and holds a tape made of hydrophilic or hygroscopic material. The tape is pre-soaked with water and can include a heating element. The heating element heats the tape and the stored water to release the stored water as vapour and thereby humidify gases passing through the inline humidifier.

Seal

An electrically conductive plastic (ECP) material can be used to heat water in a reservoir of a respiratory humidifier to encourage heating and/or humidification of gases passing through the respiratory humidifier. The electrically conductive plastic material can at least in part overmould the base and/or walls of the chamber and/or the reservoir of the respiratory humidifier. The reservoir can also partially or fully be formed from the electrically conductive plastic material.

Heating arrangements for humidification systems

In one embodiment, a filter assembly for use in an insufflation system is described. The filter assembly comprises: a filter medium operative to filter medical gases; a housing comprising an inlet, an outlet and the filter medium, the housing defining a gases flow path through the filter medium between the inlet and the outlet; and at least one heating element being positioned in the housing and being configured to heat the filter medium; and wherein, the at least one heating element is spaced apart from the filter medium and from an inner surface of the housing.

Filter assembly

An interface assembly comprises a nasal mask that includes a seal having a rolling portion. The rolling portion of the seal rolls over a portion of a clip that secures the seal to a frame. The frame has a ball and socket connection to a connector. The connector comprises an elbow having integrally formed exhaust holes and a swivel.
