Historical information

This pessary came from Professor Geoff Bishop's rooms, Mollison House, 386 Albert Street, East Melbourne. As well as the UK, Portex had divisions in the USA and Canada.

The pessary was originally regarded as an instrument and made from cork, ivory, hard rubber or gum-elastic. In later times, they were made from black vulcanite, flexible tin, soft copper wire covered with Indian rubber, and celluloid. The form of the pessary was and still is variable -either round, oval, or moulded in some cases combining three or four curves depending on the size of the pessary.

In ancient time, medicated pessaries were made from emollient. astringent and aperient. Several of these are still used, but in more modem times are called vaginal suppositories. Anal suppositories are still used to suppress the pain of haemorrhoids.
