基于经皮低频电刺激的电子孕妇止吐仪的设计与研发

Design and Development of Electronic Antiemetic Instrument for the Pregnant Based on Transcutaneous Electrical Nerve Stimulation

根据经皮电刺激(Transcetaneous Electrical Nerve Stimulation,TENS)原理以及中医经络穴位理论设计一种能有效降低由于妊娠等引起的恶心呕吐反应的穿戴式电子止吐仪。内关穴是中医常用的减少气滞、胃气上逆等恶心呕吐反应的穴位。经皮电刺激可通过模拟生物电生理信号,抵消或削弱前庭产生的过量生物电,减少和阻止前庭神经冲动向中枢传递。在内关穴进行TENS治疗,可以提高前庭器官对各种运动刺激的耐受性,使得胃蠕动波恢复正常频率,胃蠕动正常后,恶心和呕吐现象就会停止,从而起到很好的预防呕吐的效果。经实际测试,TENS有效减少了孕妇恶心呕吐反应。

To design a wearable electronic antiemetic device that can effectively reduce the nausea and vomiting caused by pregnancy, according to the principle of transcutaneous electrical nerve stimulation （TENS） and the meridian acupoint theory of Chinese medicine. Neiguan acupoint is commonly used in traditional Chinese medicine to reduce ？atulence, stomach upset, nausea and vomiting. TENS can offset or weaken the excess bioelectricity produced by vestibulethe by simulating the biological electrophysiological signals, which can reduce and prevent the vestibular nerve impulse to the central transmission. TENS treatment in Neiguan acupoint can improve the tolerance of vestibular organs to various motor stimuli, so that the gastric motility wave returns to normal frequency. Then the nausea and vomiting will stop, with a good effect of preventing vomiting. The actual test showed that TENS could effectively reduce the reaction of nausea and vomiting in pregnant women.
