Hunan Liuyang Medical Instrument Factory

Hunan Liuyang Medical Instrument Factory is a China-based medical device and diagnostic consumables manufacturer focused primarily on vacuum blood collection systems and related disposable medical products. The business is closely associated with the SANLI brand and appears to operate within the broader Hunan SANLI group, with more recent operating references pointing to Liuyang Sanli Medical Technology Development Co., Ltd. Its core products include disposable vacuum blood collection tubes, blood collection needles, tourniquets, and related laboratory and clinical consumables sold to hospitals and diagnostic settings. Historical company descriptions state that the business began blood collection tube production in 1991 and developed large-scale automated manufacturing capacity in Liuyang, Hunan. The company is commercial-stage rather than a drug developer, with revenue generated from marketed medical products rather than a therapeutic pipeline.
