AI Technical Summary

Technical Problem

In existing bone marrow stem cell separation equipment, the angle between the separation bottle and the cylinder causes the threaded connection to be unstable, which may come off during the centrifugation process, affecting the stability and safety of the equipment.

Method used

The detachable drum design is adopted, combined with circumferential limit components and quick-release components. The handle and clamping components are used to achieve a stable connection between the drum and the drive component. The limit grooves and limit plates are used to limit axial movement. The shock-absorbing parts are combined to reduce vibration and ensure the stability of the equipment during high-speed operation.

Benefits of technology

It improves the installation and disassembly efficiency of the equipment, avoids the slippage of the drum and the driving parts, enhances the stability of the connection, reduces the impact of vibration on the equipment, and ensures the separation effect and safety.
