Publication number: 20210267714Abstract: The present invention provides a clamp (10) for clamp for retaining a medical device in a medical apparatus. The clamp (10) includes a pair of opposed gripping elements (16). At least one of the gripping elements is substantially rotatably moveable to grip and apply a compressive force on a portion of the medical device when the portion it is placed between the gripping elements. The compressive force increases when the at least one of the gripping elements rotates in one direction and reduces when it rotates in an opposite direction.Type: ApplicationFiled: June 14, 2019Publication date: September 2, 2021Applicant: Saban Ventures PTY LimitedInventors: Stephen Lea, Richard Jones

Publication number: 20210244841Abstract: A droplet bandpass filter and method of modifying droplet size distribution of a population of droplets suspended in a gas. Droplets suspended in a gas are flowed through a bandpass filter having a tortuous pathway which comprises at least one impactor region located at a position adjacent to a flow direction change. Larger droplets impact at the impactor region while smaller droplets remain suspended in the gas and flow in the first output direction. Other flow restrictors may advantageously be included in the tortuous pathway. The filter is particularly useful in delivering sterilant aerosols (e.g. peroxides) with reduced populations of large droplets.Type: ApplicationFiled: June 11, 2019Publication date: August 12, 2021Applicant: Saban Ventures PTY LimitedInventors: Stephen Lea, Phuong Tran

Patent number: 10400773Abstract: A variable speed blower for Continuous Positive Airway Pressure (CPAP) ventilation of patients includes two impellers in the gas flow path that cooperatively pressurize gas to desired pressure and flow characteristics. Thus, the blower can provide faster pressure response and desired flow characteristics over a narrower range of motor speeds, resulting in greater reliability and less acoustic noise.Type: GrantFiled: June 20, 2013Date of Patent: September 3, 2019Assignee: ResMed Pty LtdInventors: Geoffrey D. Daly, Alexander Virr, Stephen A. Lea, Dion Charles C. Martin, Nicholas J. Reed, Larry Puckeridge, Timothy Tsun-Fai Fu
