However, in the existing technology, traditional intravenous infusion devices cannot automatically stop infusion when the drug is finished. Patients, family members or medical staff need to continue to pay attention to the progress of infusion, which not only consumes a lot of manpower, but may also cause patients to be unable to rest peacefully during the infusion process. Moreover, if the infusion is not handled in time after completion, venous blood may flow back because the pressure in the infusion tube is lower than the venous pressure at the infusion site, causing blood to flow back into the infusion tube.
