This equipment was located in the outpatients department (Philip Block) until September 2021 when it was deemed obsolete by Infection Prevention. Hubert Ingham Clements (1886-1969) was an Australian engineer who established his own engineering business in NSW in 1908 manufacturing combustion engines. He became interested in anaesthesia equipment and from the 1920s Clements worked on improving ether apparatus and manufacturing portable suction machines for use in hospital operating theatres. The latter machines were to earn an unrivalled reputation for reliability; many remained in service over thirty years after their date of production. The business became H. I. Clements & Son when his son William joined the company.
