Patent number: 11197967Abstract: 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.Type: GrantFiled: March 28, 2019Date of Patent: December 14, 2021Assignee: Fisher & Paykel Healthcare LimitedInventors: Michael Joseph Blackhurst, Nina Caroline Heatley, Daniel John Smith, Hussein Kadhum
