Research on the Mathematical Model of a Thermostatic Medical Irrigation Pump

چکیده
Abstract: The medical irrigation pump is a common medical device for cleaning the wound in the surgery. A thermostatic irrigation pump with a PID (proportional-integral-derivative) controller was designed to provide warm solution nearing the body core temperature for surgical irrigation. Firstly, an experiment was designed to obtain the step response curve, so as to derive the mathematical model of the system at different flow rates. Then, a simulation model was established to verify our design. Finally, discussions were given to the experiment. The result showed that the temperature of the solution could maintain at 36±1.5°C with slight fluctuation.

Introduction: Breast milk health is one of the most salient elements in feeding of premature infants. Generally in initial of breast feeding, different methods of disinfecting such as irrigation with usual detergents like water and soap are used to eliminate the probable bacteria. The necessity of the usage of such items has not been mentioned in some studies, and even at the tim...
متن کاملEffects of ionic parameters on behavior of a skeletal muscle fiber model
All living cells have a membrane which separates inside the cell from it's outside. There is a potential difference between inside and outside of the cell. This potential difference will change during an action potential. It is quite common to peruse action potentials of skeletal muscle fibers with the Hodgkin-Huxley model. Since Hodgkin and Huxley summarized some controlling currents like inwa...
متن کاملAssessment of energy efficiency in pump stations of pressurized irrigation systems (case study: Qazvin and Kermanshah provinces)
About 20% of the electricity produced in the world is consumed in rotary equipment for conveying fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study is to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stati...

As pressurized irrigation is not possible for all circumstances, the use of modern techniques in surface irrigation is essential. In this paper, BISEDOM, a new mathematical model for evaluation, design and optimization of border irrigation is introduced. The effects of weighting coefficients of indicators are investigated based on the potential to improve and the most appropriate weighting sche...
متن کاملOff-Pump Versus On-Pump Coronary Artery Bypass Graft Surgery, prospective cohort study
Introduction: Coronary artery bypass grafting is a surgical operation that bypasses atherosclerotic coronary vessels and restores blood flow to the ischemic zone of hearts. And two different conventional methods are ON-pump CABG, and Off-pump CABG. Altogether, the efficacy and safety of these two types of surgical procedures are still under debate. In this study, we aim to com...
