Through the venous infusion port technology, a permanent venous access can be established, which has solved the problem of frequent replacement of infusion lines for the elderly, patients with chronic diseases or tumor patients, and facilitated the rescue and medication of patients. The problem of access to difficult blood vessels has been solved.

At present, the catheter system mainly includes butterfly-wing atraumatic needles (straight and curved), extension tubes, and fixed wings. The needle and needle handle of the butterfly-wing atraumatic needle are at 90°, and the needle wings are flat on the injection seat after puncture. After the infusion or rehydration is finished, it is necessary to pull out the butterfly wing non-injury needle of the infusion port. When the nursing staff adopts the traditional extraction method, they need to use the thumb, index finger and middle finger of one hand to form a triangle to fix the injection seat of the infusion port, and use the other hand to fix the injection seat of the infusion port.
