In terms of its design concept, the main purpose is to allow the artificial blood vessels to be placed in the patient's body for a long time, so that medical staff can directly provide medical care through the artificial blood vessels. Chemotherapy drugs are given to patients, and this type of artificial blood vessel device allows cancer patients to avoid the need for indwelling soft needles or other tubing methods like ordinary ones. That is, patients with artificial blood vessels do not need to regularly replace the indwelling soft needles and related tubing.

However, when cancer patients are provided with artificial blood vessels for chemotherapy, medical staff mainly use curved needles to insert the artificial blood vessels, and then inject the chemotherapy drugs into the artificial blood vessels through the curved needles, and then allow the chemotherapy drugs to flow into the connected organs through the artificial blood vessels. Human blood vessels allow chemotherapy drugs flowing into the cancer patients' human blood vessels to treat cancer patients. However, during the treatment process of cancer patients, chemotherapy drugs will also kill good cells. Therefore, cancer patients are prone to disease due to reduced immunity. There is a higher chance of being infected by other bacteria. Among the causes of infection, improper placement or operation of bent needles by medical staff is the main reason.
