ABSTRACT
Objective To investigate the effects of different degrees of white mustard stir-processing on patient skin after acupoint application. Methods The same production batch of raw white mustard were randomly allocated to groups A, B and C. Fifty asthma patients were received acupiont application. Raw white mustard was stir-processed into slight yellow in group A, deep yellow in group B and coke yellow in group C. the skin reaction was observed in the three groups of patients after acupoint application. Results Obvious skin burning heat and burning pain sensations, and skin redness accompanied by many blisters occurred at the place of application in group A. Skin warming sensation, no or a small amount of needle tip-like blisters and skin redness without edema occurred at the place of application in group B. No or slight skin redness and unobvious skin warming sensation occurred at the place of application in group C. Conclusion White mustard stir-processed into deep yellow can effectively reduce the excessive stimulation of medicine to the skin and not markedly affect the amount of medicamentous stimulation to the acupoint.
ABSTRACT
To develop a standard defibrillation energy source which can output monophasic and biphasic de-fibrillation impulses and can display standard energy values. The storage capacitor was charged by single-end flyback transformator and discharged through the H bridge composed of insulated gate bipolar transistor (IGBT). Impulse voltage and current were collected by divider while discharging, and the energy value was calculated by STM32. The en-ergy value and waveform were displayed through the control module. The energy source could output both monophsic and biphasic waveforms, and the accuracy of displayed value was higher than ±2% or ±1 J. The standard defibrillation energy source can be used as standard device for defibrillator analyzer, and the metrological trace-ability system of defibrillation energy may come to be completed.
