<p>An insulin infusion adapter port capable of being attached/detached in any direction comprises an infusion port upper cover (1), an infusion port base (2), an indwelling-needle base (3), a silicon rubber sealing ring (4), an indwelling needle (6) and a puncturing steel needle (5). An infusion hole (11) consisting of an access hole (112) and an upper central hole (111) is formed on the infusion port upper cover (1). The steel needle (5) pierces the silicon rubber sealing ring (4), and the indwelling needle (6) is embedded in a lower central hole (31) of the indwelling-needle base (3). When used, the indwelling needle (6) is inserted, at a desired injection point, subcutaneously into the skin of a diabetic, and the indwelling needle base (3) is arranged on the skin surface of the diabetic. The insulin is injected into the diabetic successively through the steel needle (5) and the indwelling needle (6) when an insulin injection is needed. The access hole (112) can be directly matched with a needleless injector or indirectly matched with an insulin infusion pump, allowing for better usability. The infusion port upper cover (1) can be rotated and adjusted as required by users, and is convenient in use. The insulin infusion adapter port capable of being attached/detached from any direction can effectively reduce financial burden of patients and prevent pains of repeated injections, and is easy to use.</p> |
