Title: Surgical instrument sterilization by bactericidal medium - admitted after evacuation and stored for recycling after use
Inventor: GENZE MANFRED
IPC: A61L2/20
Filed: 1973-03-19
Abstract: In a sterilization process for surgical instruments, the sterilizer space is first evacuated to 0.01 Torr before the bactericidal gaps or vapour is admitted. The sterilizing medium is extracted by a vacuum pump after a set time of action and is stored. In a subsequent working cycle, the medium is admitted again into the sterilizer space. This process can easily be automated by a programmer control. The working cycle is completed rapidly and effectively. No bactericidal gases or vapours can escape into the environment.
