A device for extracting umbilical cord mesenchymal stem cells

Abstract

This utility model discloses a device for extracting umbilical cord mesenchymal stem cells, belonging to the field of biomedical engineering technology. It includes a transmission gear plate, a rotating structure, an adjusting structure, and a fixing structure. The adjusting structure drives a threaded block to move along a guide rod via a threaded rod, achieving precise adjustment of the centrifuge tube's tilt angle. The rotating structure, through a locking block and locking groove, supports multi-degree-of-freedom adjustment of the tube's opening orientation. The fixing structure employs air-filled balloon technology, using the inflated balloon to clamp the tube, preventing mechanical damage and adapting to different tube sizes. The device, driven by the transmission gear plate, rotates as a whole, and combined with dual-degree-of-freedom adjustment, significantly improves cell sedimentation efficiency and ease of operation, making it suitable for the efficient separation and extraction of mesenchymal stem cells from umbilical cord, bone marrow, and other sources.
