SageTech’s technology has been developed to provide a holistic market solution, adapted according to the two types of anaesthetic case – short and long duration:
The process operates on an industrial, litre-scale for bulk capture, extraction and purification. A capture canister is placed between the anaesthetic machine and anaesthetic gas scavenging system (AGSS) and captures waste anaesthetic gases (see diagram). The canister is then loaded into an automated extraction machine which is located on hospital premises. The machine extracts the captured gases and condenses them to liquid form. This waste liquid, comprising the three main agents (Isoflurane, Sevoflurane and Desflurane), is stored within the machine. Once machine capacity is reached (approximately 30L), transportation of the bulk liquid waste to our processing facility for purification is arranged.
Capturing waste anaesthetic paves the way for the removal of the Active Gas Scavenging System (AGSS), which exists to vent waste anaesthetic gases to the atmosphere. The AGSS is an expensive and restrictive element of theatre design and removing it would allow any suitable space to be used as an operating theatre. This would bring about a new era in flexible theatre design.
This flexibility could mean the use of volatile anaesthesia be extended to areas not typically serviced by an AGSS such as ICU.
