China NMPA Product Recall - Doppler fetal heart monitor

Shenzhen Weikangming Technology Co., Ltd. initiated a voluntary Level III recall of its Doppler Fetal Heart Monitors (model FD-200B) on August 13, 2019, reported to the National Medical Products Administration (NMPA). The recall stemmed from a compliance issue where the V1.0 version of the product's instruction manual did not disclose audio output parameter information. This omission, while not affecting product safety, performance, or causing user harm, violated national mandatory standard GB 9706.9-2008, specifically Clause 6.8.3, which outlines safety requirements for medical electrical equipment manuals. The company's required actions included immediately notifying all affected customers via letters, informing them of the issue and providing the missing audio output parameters. Crucially, this recall did not involve the physical removal of products, allowing existing units to remain in normal use. Corrective measures focused on revising the V1.0 instruction manual to include the necessary sound output parameters. For products already sold, customers received a "Medical Device Recall Notice" and a revised instruction manual page through distributors for manual updates. Any returned products would undergo instruction manual revision, re-inspection, and subsequent re-storage, ensuring regulatory adherence without impacting product utility or user safety.
