As we all know, the world’s largest port is the Port of Rotterdam in the Netherlands, located in the southwestern part of the Netherlands on both sides of the Rhine estuary area of the New Maas River, 28 kilometers away from the North Sea, is the world’s largest port and the second largest city in the Netherlands, the port’s annual throughput of more than 500 million tons. And now in the field of clinical medicine, there is a “port” of infusion – a fully implantable infusion port. When it comes to infusion, people often associate it with steel needles for puncturing and drawing blood. From the initial steel needle puncture infusion, to intravenous indwelling needles, to PICC, and then into the new century and the emergence of infusion port, the choice of infusion route is more diversified and humanized. Fully implantable infusion port is a kind of intravenous infusion device implanted under the skin and left in the body for a long period of time, consisting of an injection seat for puncture and a catheter system inserted into the vein, like a multi-functional “port”, which can be used for infusion of all kinds of medicines, rehydration, nutritional support therapy, blood transfusion, blood sample collection, etc.; it is equipped with a low risk of infection, easy to use and long term, easy to maintain, It has the advantages of low risk of infection, long duration of use, simple and convenient maintenance, and high quality of life of patients, which is gradually accepted by patients and clinical medical personnel, especially for patients who need long-term infusion and have poor condition of peripheral superficial blood vessels. Now the port of infusion – fully implantable infusion port, the use of time can reach more than ten years, assuming that the patient infused 500 ml per day, 200 days of infusion per year, the use of ten years, through this “port” into the body of the amount of liquid will reach 1 ton weight, about This is equivalent to twenty times the weight of an adult.
