And then, wiping the pipe outwards in a spiral mode by using a complex iodine cotton ball with the infusion port as the center of a circle, wherein the radius of the complex iodine cotton ball is about 10-12 cm, and repeating the steps for three times. Then, the atraumatic disc-wing needle was again evacuated with more than 10ml of physiological saline from the disposable empty needle, and the extension tube was clamped closed. Afterwards, palpation localization was used to locate the septum, i.e.: firstly, making a triangle by using a thumb, an index finger and a middle finger of a non-dominant hand, fixing the infusion port and determining the middle point of the three fingers; the disc wing needle is gently inserted into the puncture septum vertically from the middle point of the transfusion port until reaching the bottom of the liquid storage tank. Finally, the clamp of the extension tube is opened, blood is drawn back to determine the correct position of the needle, and after the infusion port is flushed by means of a pulse of physiological saline, the extension tube is clamped and the syringe is detached and covered with a sterile dressing. When in transfusion, the transfusion device is connected with the extension tube, the clamp is released, and the medicine is slowly injected; meanwhile, whether the injection part has the liquid seepage phenomenon is closely observed; once an abnormality is found, the injection is immediately stopped and appropriate action is taken. The conventional processes described above have problems in that: the puncture seat of the implanted infusion port is mostly triangular with smooth corners and ends, and during the puncture operation, because the surface area of the protruding part is smaller, on one hand, the sight of an operator can be influenced by fixing the base of the infusion port by hands, and the one-time success rate of inserting the butterfly wing needle into the infusion port is reduced; on the other hand, the puncture is easy to be caused during the puncture action, thereby greatly reducing the working efficiency and increasing the time cost. In addition, when the butterfly wing needle is normally used for puncture, the penetration depth of the butterfly wing needle has requirements, the needle head penetrates through the base of the infusion port due to the fact that the needle head is too deep, the service life of the infusion port is rapidly shortened, and the formation of a liquid flow channel cannot be guaranteed due to the fact that the needle head is too shallow, so that the requirement on an operation threshold is high, and a lot of troubles are brought to actual nursing work.
