Result The DFAC does not disintegrate in hypoderm, and the degradation rate is ( 8.10 ± 2.31)% after 180 days. 结果DFAC不崩解,180d降解率为(8.10±2.31)%,具有较稳定的缓释作用。
Needle-free injection drag delivery, is a new method which accelerates liquid drag to a certain velocity to penetrate the outer layer of the skin, reaches hypoderm, muscle or mucous membrane site and releases in particular organization, and shows the efficacy of the drag. 无针注射给药,是一种利用高压将液体药物加速至一定的速度,药物穿透皮肤外层递送至皮下、肌肉或黏膜部位,并在特定组织层释放,发挥药效的新型给药方式。
However, for detected from skin surface with bigger sized electrodes, and influenced by low-pass-filter effect of muscle, hypoderm and skin, the sEMG signal has a lower signal noise ratio, a higher waveform dissimilation, and a higher difficulty in detections and processes. 但由于是从皮肤表面检测信号且电极面积较大,同时受到肌肉、脂肪和皮肤组织的低通滤波效应影响,其信噪比较低,波形变异性较大,对其检测和处理的难度也相应增大。
