the plastic around the injection port was observed to have fractured, with both the injection port and the Luer connector having become disconnected from the cannula tubing (Fig. 4). The Medicines and Healthcare products Regulatory Agency (MHRA) and the manufacturer were contacted, and the device was returned to the latter for evaluation. No manufacturing-related root cause for this defect was determined, and this was the first recorded complaint of this type for this lot number (2324009). We were unable to ascertain whether similar failures had occurred in other lot numbers. The manufacturer noted that high external force is required to break the cannula hub in this way, even though minimal force was used during insertion and connection in this instance. Becton Dickinson were invited to reply to this letter, but no response was received. Other cannula malfunctions have been reported in the past, mostly relating to failure of the injection port valve [1–3]. We are unable to find previous reports of failure of this type, and vigilance for recurrence should be maintained.
