The customer reported a power issue was observed while using a nova biomedical statstrip glucose meter with sn (b)(6).The device lost power after drawing a sample from a pediatric patient.Due to the power loss, it was necessary to draw an additional sample from the patient in order to measure the glucose values.This occurred on (b)(6) 2021.No additional delays in treatment were reported.The meter and battery were not returned to nova biomedical for investigation.However, the customer did return a different meter exhibiting similar problems.This meter was tested using batteries retained by the manufacturer, performing a drop test from a height of one foot and a bounce test which including lifting the bottom of the meter from a surface and dropping it down, allowing it to bounce.After performing these tests, the reported problem could not be reproduced.Device history record (dhr) reviews were performed for the meter being used at the time of the event by a quality control engineer.The reviews included an assessment of the production, testing, and release of the meter and test strips.No abnormalities or concerns were noted, and the dhr indicated the released product met all specifications.The conclusion of the investigation is the reported customer complaint could not be confirmed after testing the returned customer meter.A root cause was unable to be identified.While the reported issue was not reproduced on the returned meter, nova biomedical is working on improvements to the meter's battery housing.A new, slightly elongated design has already undergone initial testing and qualification and further testing is being completed.Nova will continue to monitor for recurrence of similar events.
