Publication number: 20240399097Abstract: Condensation or “rain-out” is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube preferably incorporating a heater wire.Type: ApplicationFiled: May 6, 2024Publication date: December 5, 2024Inventors: David John Sims, Enrico Alvarez Garcia, Peter Kenneth Graham

Patent number: 12121668Abstract: In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.Type: GrantFiled: September 11, 2019Date of Patent: October 22, 2024Assignee: Fisher & Paykel Healthcare LimitedInventors: Dexter Chi Lun Cheung, Matthew Jon Payton, Michael Barraclough, Michael John Andresen, Kieran Michael Orchard, Philip James Edgeworth, Peter Kenneth Graham, Anthony James Newland, Daniel John Smith, Timothy James Beresford Sharp, Elmo Benson Stoks, Jonathan Mark Church, Andre van Schalkwyk

Publication number: 20240189531Abstract: A patient ventilating (23) and aspirating system (9) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a sealed passageway (15). The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.Type: ApplicationFiled: November 16, 2023Publication date: June 13, 2024Inventors: Peter Kenneth Graham, Deshitha Airawana Edirisuriya, Dwayne John Scollay

Publication number: 20220379054Abstract: This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.Type: ApplicationFiled: May 11, 2022Publication date: December 1, 2022Inventors: Peter Kenneth Graham, Enrico Alvarez Garcia, Shu-Yi Chu

Publication number: 20210069447Abstract: This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.Type: ApplicationFiled: September 22, 2020Publication date: March 11, 2021Inventors: Peter Kenneth Graham, Enrico Alvarez Garcia, David John Sims
