[0002] At present, the soft tube transmission pump using soft tube as a carrier is widely used in the medical field, and the soft tube of the soft tube transmission pump needs to be cleaned and sterilized in the medical production environment with high production requirements. Since the soft tube pump mainly transmits fluid by extruding the soft tube, if the extrusion of the soft tube is not good in the online cleaning and sterilization, the extrusion of the soft tube usually needs to be disassembled from the pump body for cleaning, sterilization and other operations, and after sterilization, it is installed back into the pump body, which has defects such as troublesome operation, time-consuming and laborious, increasing the cost of enterprise labor, reducing work efficiency and the like.

When online cleaning and sterilization is performed, if the inner diameter of the extrusion soft tube is much larger than the inner diameter of the transmission soft tube at the needle filling end and the distributor end, the flow rate difference of the cleaning liquid exists in each section of the soft tube, the inner wall of the transmission soft tube at the needle filling end and the distributor end can be cleaned, but the cleaning degree of the inner wall of the extrusion soft tube is difficult to achieve the expected effect, and offline cleaning and sterilization are often used.
