[0001] This application claims priority to U.S. Provisional Application No. 63 / 581,745, filed September 11, 2023, entitled “Port Access Needle and Extraction Tool,” the disclosure of which is incorporated herein by reference in its entirety. Technical Background Technical Field This disclosure generally relates to a port access pin and a removal tool.

[0002] Description of related technologies Cancer patients are often sent home for prolonged (approximately 46 hours) medication infusions. Current practice involves returning to the clinic at a scheduled time for removal or cessation of the infusion. This is a burden on clinics, as infusions sometimes cannot be completed on time (especially when using flexible infusion pumps). Patients may therefore have to wait several hours until the medication or infusion is completely finished. A growing trend is to move these activities to the home environment, freeing up clinic space for other activities and allowing patients to perform removals comfortably at home. Simplifying home removals and building patient confidence in doing it themselves is a priority. Many people are afraid of needles, and needle removal can be uncomfortable due to the movement of the needle during dressing removal. Summary of the Invention
