Pin Index Oxygen Cylinder Valves

The Pin Index Safety System (PISS) is an essential safety measure in the medical industry. It is a precise configuration of pins and holes that connect a specific medical gas cylinder and the delivery system of these gases. This system is designed to prevent the accidental placement of a cylinder containing the wrong medical gas onto the hanger yoke of the anaesthesia machine designed for another gas. The PISS ensures that the pins on the medical gas cylinder and the holes on the hanger yoke of the anaesthesia machine are aligned correctly. The cylinder cannot be connected to the machine if the alignment is incorrect. This feature ensures that the delivery system only receives the intended medical gas.
