A new device has been developed for the application of Electrical Stimulation to improve healing of chronic wounds. The device enables the creation of a composite electrode hence matching the electrode(s) to the size and shape of the wound. Up to 49 electrodes in an array can be combined, delivering High Voltage Pulsed Current (HVPC) in the range 60-120 Hz with a pulse duration range from 90-110 mus and the possibility of treating the patient with direct current instead of HVPC. In addition, the software can import the measurements from the ImpediMap device, analysing the electrical impedance of the tissues involved. A test on healthy volunteers did not prove a statistically significant rise in skin temperature, TcPO2 or impedance due to the stimulation, even though a slight reddening of the stimulated site was observed.
一种用于应用电刺激以促进慢性伤口愈合的新设备已被开发出来。该设备能够制造复合电极，从而使电极与伤口的大小和形状相匹配。阵列中最多可组合49个电极，提供频率范围为60 - 12０赫兹的高压脉冲电流（HVPC），脉冲持续时间范围为90 - 110微秒，并且有可能用直流电而非HVPC来治疗患者。此外，该软件可以导入来自ImpediMap设备的测量数据，分析相关组织的电阻抗。对健康志愿者进行的一项测试表明，尽管观察到刺激部位有轻微发红，但由于刺激导致的皮肤温度、经皮氧分压（TcPO2）或阻抗在统计学上并没有显著升高。
