Abstract
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 thepump 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 first-aid treatment in field.
