Patent number: 11992622Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.Type: GrantFiled: June 3, 2020Date of Patent: May 28, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Sally Margaret Hensman, David Robert Kemps, Simon Mordechai Stam, Jason Allan Klenner, Andrew Paul Maxwell Salmon, Mark Samuel Hamilton, James William Stanton, Michael John Andresen, Jonathan Andrew George Lambert, Nicholas Edward Vaughan

Patent number: 11992627Abstract: Articles, such as catheters, comprising markings and associated methods are generally provided. The articles described herein may be configured to be exhibit one or more desirable properties. For instance, in some embodiments, an article comprises markings that are spaced from each other at known distances. Such markings may be employed to aid users of the article in measuring distances. As another example, an article may be configured to swell upon exposure to the fluid such that markings positioned thereon do not crack or delaminate. It is also possible for the article to be configured to swell upon exposure to the fluid in a known, predictable, and/or uniform manner. This swelling may cause the spacings between the markings to increase, and such increase may also be in a known, predictable, and/or uniform manner.Type: GrantFiled: June 28, 2021Date of Patent: May 28, 2024Assignee: Access Vascular, Inc.Inventors: Michael Bassett, Daniel T.
