Introduction
A port infusion system is generally a central venous catheter, an infusion device implanted inside the human body. The injection port of the system is completely implanted subcutaneously and connected to a vein, with the venous catheter portion positioned within the subcutaneous vein, making it a fully implantable, closed infusion system. Once implanted, it can be used for a prolonged period, avoiding repeated punctures. It also provides safer infusion and reduces drug-induced irritation to peripheral blood vessels.
Port infusion systems are typically placed in deep veins and represent a type of infusion device implanted inside the body. Regular follow-up examinations and maintenance should be performed as directed by a physician to prolong their use. Specific details are as follows:
A port infusion system mainly consists of an injection port and a venous catheter. The injection port is completely implanted under the skin into a vein, while the venous catheter portion lies within the subcutaneous vein, making it a fully implantable, closed infusion system. Once implanted, it can be used for extended periods, avoiding repeated punctures. It provides safer infusion and reduces drug-induced irritation to peripheral blood vessels. It is suitable for individuals requiring frequent blood transfusions or long-term chemotherapy.
After use, the catheter is typically sealed with heparin sodium injection solution. In daily life, excessive pressure or squeezing on the implanted site should be avoided.
