【Abstract】 Aimed at the research requirements of micro-injection and painless injection,combined with the injection principle in clinical medicine,a combination of hardware and software was used to developed a syringe penetration force measurement system with the characteristics of controllable speed,adjustable angle and stable work.In experiment researches,standard weights were used to measure the performance indicators of the system,where the sensitivity could reach 0.003 V/mN and the system response time was less than 100 ms,with the maximum hysteresis of 1 mN and the repeatability error of ±303 μN.Meanwhile,in order to verify the actual performances of the system,silicone that simulates artificial skin was used in the syringe penetration force test experiments.The results show that the developed syringe penetration force measurement system can meet the actual requirements for syringe penetration force measurement.Therefore,this system not only could be used to measure the penetration force of various syringes,but also could be used in other fields related to micro-force measurement.更多还原
