A conduit with a collapsible portion, and a nasal interface for providing a flow of gases to a user, is described. The interface comprises a manifold and at least one nasal prong or an outlet extending from the manifold to be received by a user's nare. A side member extends from each side of the manifold, each side member comprising a collapsible portion comprising a lumen. In an open configuration the lumen remains open and in a closed configuration the collapsible portion is pinched or flattened to occlude or substantially occlude the lumen. At least one of the side members is a conduit for a flow of gases from an inlet of the patient interface to the manifold.

Various systems and methods are provided for creating a wicking structure. In one example, a method for creating a wicking structure can include creating, using a 3D printing technique, a macro wicking element comprising a lattice structure formed by a grid of a first material, the lattice structure comprising pores formed between the grid of first material. The method can also include creating, using the 3D printing technique, a first micro wicking element comprising powder particles distributed within the pores of the lattice structure, and creating, using the 3D printing technique, a second micro wicking element by removing at least a portion of the lattice structure.

Apparatus for direct oral delivery of fluid medical gas to a patient, comprising: a conduit, a mouthpiece in fluid communication with the conduit, an exhalant chamber at least partially divided from the conduit, an outlet valve in one-way fluid communication between the conduit and the exhalant chamber, the outlet valve adapted for permitting exhalation of exhalant by the patient into the exhalant chamber and adapted for porting of the exhalant outside of an environment in which the apparatus is adapted for use.

A connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The outer body is configured to be slidable along the inner body between each of an inoperative orientation and an operative orientation with respect to the inner body. The outer body and the inner body are configured to be in engagement or in an operative association with each other when the outer body is provided in the operative orientation. The outer body and the inner body are disengaged from each other or in an inoperative association with each other when the outer body is provided in the inoperative orientation. At least one or each of a surface of the inner body or a surface of the outer body comprises of a surface relief feature(s) providing for a resistance to the outer body being moved from the inoperative orientation to the operative orientation.

A system may comprise a connection member configured to be connected to an anatomic orifice device. The anatomic orifice device may be configured for insertion into a patient. The system may also comprise a mounting bracket coupled to a robot-assisted medical system. The mounting bracket may also include a movable mounting component coupled to a fixed mounting component. The movable mounting component may have a first configuration for mounting to the connection member in a first engagement and a second configuration for mounting to the connection member in a second engagement. The connection member may be spaced apart from the fixed mounting component in the first engagement and may be in direct contact with the fixed mounting component in the second engagement.

An anesthesia vaporizer system includes a sump chamber, a variable volume reservoir within the sump chamber, and an anesthetic vaporizer. The variable volume reservoir is configured to contain anesthetic agent. A pressurized gas source is connected to the sump chamber and configured to maintain a constant pressure within the sump chamber to compress the variable volume reservoir to force the anesthetic agent through the anesthetic vaporizer, which vaporizes the liquid anesthetic agent for delivery to a patient.
