What type of connectors must be used in non-accessible hose or flexible station outlets?

DISS connectors, or Diameter Index Safety System connectors, are specifically designed for use in non-accessible hose or flexible station outlets in medical gas systems. These connectors are constructed to provide a safety mechanism that helps prevent the incorrect connection of gases, ensuring that only the appropriate gas can be connected to its specific outlet.

DISS connectors achieve this through a unique design that varies the size and shape of the outlet and plug, making it impossible to connect a gas hose to an incompatible outlet. This is particularly important in medical settings, where the risk of mixing gases such as oxygen, nitrous oxide, and medical air can have serious consequences for patient safety.

Using DISS connectors in non-accessible areas ensures that even if the outlet cannot be easily reached or inspected, the system complies with safety standards designed to protect both patients and healthcare providers from errors related to gas delivery. This focus on safety and compatibility is a fundamental principle in the management of medical gas systems.
