piCObaby™ Consumables

Years of research and vigorous testing ensures our Bedfont® products and consumables are not only safe for consumer use, but compliant with Medical Device Regulations. Use of counterfeit or non-Bedfont® approved accessories and consumables may result in loss of performance and/or damage to your device. This risk of incorrect results could adversely affect patient care. We also remind you that counterfeit and/or non-Bedfont® accessories and consumables do not possess the quality and reliability of the original manufacturer products, nor have they undergone the Toxicology tests to ensure they are fit to be used orally, and therefore their safety and infection control efficacy cannot be guaranteed.
