低频电湿热治疗机可在输出低频类方波脉冲电流时,同时施予湿热,从而提高理疗疗效。该机原理图见附图所示。IC_1输出的脉冲,其频率由W_1、C_3及RC电路决定。IC_2组成放大部份,B_2为输出变压器。W_2可调节输出强度。电极内由镍合金丝绕制,外包纱布,浸湿后置于治疗部位,在0～36V范围内,分五档调温。使用该机治疗,患部有麻震感及湿热感,适用于急慢性软组织扭挫伤、肌肉酸痛及劳损,具有较好疗效。 Low-frequency electrothermal heat treatment machine can output low-frequency square wave pulse current, while giving damp heat, thereby enhancing physical therapy efficacy. The schematic diagram shown in the drawings. The pulse output by IC_1, whose frequency is determined by W_1, C_3 and RC circuits. IC_2 enlarge part of the composition, B_2 for the output transformer. W_2 adjusts output intensity. Electrode by the nickel alloy wire wound system, outsourcing gauze, placed in the treatment area after soaking, in the 0 ~ 36V range, sub-five temperature. The use of the machine treatment, the affected area has a sense of Ma shock and heat, apply to acute and chronic soft tissue contusion, muscle soreness and strain, with good effect.
