Objective： A novel portable and intelligent fluid resuscitation infuser is proposed in this paper. It satisfies the demands of long time use in harsh environment, such as traffic accident, natural disaster, battlefield, evacuation, pre-hospital emergency and so on. Methods： Miniature linear motor and liquid blood cartridge compose the pump body. It＇s based on the biological impedance method to measure and control, which resolve the disadvantage of traditional infuser device： large power dissipation, big size, AC power supply only and can＇t be use in field. The whole device weights 250 gram and sizes as two mobile phone together Results： Model device experiment shows： six number 7 standard AAA size alkaline batteries will run the pump for approximately 8-10 h at 6 liters per hour; IV bag can be placed at any position of patient, even under the stretcher. Conclusion： It provides accurate and reliable intravenous infusion for fwst-aid treatment in field.
