A Reusable Three limb Circuit is a medical device used in mechanical ventilation and anesthesia delivery systems. It is designed to deliver respiratory gases to and remove exhaled gases from a patient during surgery or when mechanical ventilation is required. These circuits are typically made of durable materials, such as plastic or silicone, that can withstand repeated sterilization and cleaning procedures. This allows them to be used for multiple patients. Reusable Three limb Circuit is designed to be compatible with specific anesthesia machines or ventilators, and they often have standardized connectors to ensure a secure and leak-free connection.
