A demand valve is a non-sterile, reusable device that controls the flow of therapeutic gas to a patient by responding to their breathing effort. It delivers gas only when the patient inhales, making it efficient for use in ventilator circuits, resuscitation equipment, and on-demand analgesia systems where precise, patient-triggered gas delivery is required.
Devices in this category are regulated as reusable medical devices and are typically supplied for repeated use after appropriate cleaning, disinfection, or sterilization between patients. They are not sterile upon supply and rely on user-driven inhalation to activate gas flow, distinguishing them from continuous-flow or pressure-regulated systems.
