Peristaltic Pump
A pump that moves fluid by sequentially squeezing a flexible tube, so that the fluid contacts only the tube and not the mechanical components directly. It offers good sealing, low contamination risk and precise metering, and is widely used in medical and industrial applications.

The interior of a bee's stinger consists of multiple groups of independently moving valves and chambers, which can push venom forward stage by stage in a wave-like peristaltic manner, rather than a simple tubular structure squeezed by muscles.
The working manner of a bee's stinger is highly similar to an industrial peristaltic pump: by successively squeezing an elastic hose, the fluid is pushed forward segment by segment, and the fluid only contacts the hose and not the pump's mechanical parts directly, offering advantages of good sealing, low contamination risk, and precise metering.
