In order to relieve the pain of patients, reduce the hospitalization cost of the patients, facilitate long-term high nutrition treatment and the like, the application of the intravenous catheters is increasingly increased clinically. Currently, shallow venous indwelling needles, Central Venous Catheters (CVCs), percutaneous central venous catheters (PICCs), and the like are mainly used. However, if the venous catheter is subjected to complications such as catheter-related blood flow infection, blockage, thrombosis and the like, not only the hospitalization time of the patient is prolonged, but also the medical cost and the fatality rate of the patient are increased by colleagues. The most common complication is tube blockage, and studies show that the tube blockage rate is 31.1 percent or even higher. Effective maintenance of the intravenous catheter becomes critical to address this, and effective placement of the occlusion becomes central. At present, pulse type positive pressure flushing and sealing pipes are adopted clinically, but different flushing and sealing pipe effects can be caused by different flushing and sealing pipe methods and different force of clinical medical staff. On the other hand, the blood backflow in the venous catheter after the catheter is flushed causes the blockage due to the self-reason of the patient, such as the over-exertion of the limb after the catheter is placed, or the violent cough. Therefore, there is a need for a device capable of performing continuous positive pressure flushing to effectively prevent blood from flowing back and blocking the tube.
