Design and Fabrication of a New MHD Micropump for Continuous Subcutaneous Infusion to Thalassemia Major Patients

Background: In recent decades, reducing the size of drug delivery systems along with precise control amount pumped, has attracted attention many researchers. Objectives: The slow subcutaneous infusion deferoxamine in thalassemia major patients during day is vital importance either for effectiveness. However, this difficult to achieve due large conventional pumps and their high weight. Therefore, weight reduction are very important issues that must be well addressed. Methods: A biomedical micropump solution human body based on magnetohydrodynamic (MHD) concept designed, its performance experimentally investigated research. key challenge fabrication size, weight, bubble generation, operating voltage. Results: present design responded these problems. final operates a 1.2 v without any while 20 × 40 50 mm3 90 grams, respectively. about 1/3 micropump, half them. Conclusions: newly designed ability inject sufficient rate disturbing them, so it can increase quality life expectancy.
