Embedded tube for chemotherapy is a catheter left in the deep vein for infusion, through which chemotherapy drugs can be dripped intravenously to avoid stimulation of peripheral blood vessels. The toxic side effects of chemotherapeutic drugs are relatively large, easy to damage the blood vessel wall and surrounding tissues, resulting in phlebitis, local pain, etc. Once the chemotherapeutic drugs are extravasated, resulting in local muscle necrosis, the infusion of fluids through the embedded tube can effectively avoid the damage of the chemotherapeutic drugs to the peripheral superficial blood vessels. Clinically, according to the length of chemotherapy and the patient’s vascular condition, different tube placement methods can reduce the number of puncture, reduce the patient’s pain, and protect the patient’s blood vessels. Embedded tube is not only suitable for chemotherapy patients, but also for long-term infusion of high concentration of drugs, poor vascular elasticity of the elderly patients.
