The SCI device is constructed using a steel impounder inserted into a Teflon base. The impounder is attached to the end of the hollow tube by a horizontal pin to guide the weight and to prevent it from bouncing on impact. The weight is made of Teflon coated stainless steel and is supported by a removable pin which is also used to release the weight. Rod magnet is used for retrieval of the weight after the injury.
Scavenging machines are used in the collection and removal of waste anesthetic gases (WAGs) vented during the anesthetization processes. These systems comprise collection devices, interfaces, and disposal systems. Scavenging machines also help monitor the gases and prevent barotrauma to the subject resulting from a change in incoming and outgoing gas flow.
