The principle of the peristaltic pump is to transfer the liquid by squeezing the hose, and the liquid only contacts with the hose. By replacing or cleaning the hose in the later stage, it can ensure cleanliness and sterility, in line with the safety regulations of medical devices. Other pump liquids pass through the pump body, which is difficult to clean and disinfect. Therefore, in the liposuction industry, peristaltic pumps are the best choice.
