What Is a Pin Index Oxygen Regulator?
The VM-RPI (MD870-UF) is a CGA870 pin-index style medical oxygen regulator designed for small portable oxygen cylinders commonly used in ambulances, emergency departments, and patient transport. The pin-index safety system (PISS) uses a unique pattern of pins on the regulator yoke that physically matches only the correct cylinder valve ? preventing accidental connection of the wrong gas. CGA870 is the international standard for portable medical oxygen cylinders.
Clinical Applications
Pin-index regulators are the standard choice for portable oxygen cylinders used in pre-hospital care, patient transport, and bedside supplemental oxygen therapy in ward and clinic settings. The VM-RPI’s 0?15 L/min flow range with 12-level adjustment covers all clinical oxygen delivery modes ? nasal cannula, simple mask, partial rebreather, non-rebreather, nebulisation, and oxygen-powered resuscitation. The compact, lightweight aluminium body keeps the cylinder assembly portable for ambulance and paramedic use.
Safety and Certification
The pin-index design is a critical safety feature ? without it, a high-flow oxygen regulator could theoretically be connected to a nitrous oxide cylinder, with potentially fatal results. The VM-RPI is certified to ISO 13485, CE, FDA, and ASTM G175-03, confirming its construction and materials meet the standards for medical oxygen service. The outlet pressure of 50PSI is compatible with standard oxygen delivery devices and driven resuscitators.
