Translated fromChinese技术领域technical field
本发明涉及射频理疗技术领域，具体为一种具有实时温度控制功能的便携式射频理疗仪。The invention relates to the technical field of radio frequency physiotherapy, in particular to a portable radio frequency physiotherapy instrument with real-time temperature control function.
背景技术Background technique
射频治疗设备是通过射频电磁场作用于人体组织，使其产生热效应和非热效应，从而达到治疗目的的一种物理治疗设备，其一般的工作原理是：由射频发生器产生射频电流，经滤波、功率放大和耦合检波后，再传送到射频辐射器辐射出去形成电磁场。目前射频治疗设备主要是热效应的应用，由于射频能量产生的热效应能对生物组织产生深部透热作用，因此在临床的应用已经十分广泛。然而，已有的射频治疗设备一般都是采用电子管振荡器作为功率源，辐射器由成对的电容电极板组成，功率源与辐射器之间通过同轴电缆进行功率传导，有较大的能量传导损耗，因此都是只能在固定场合使用的大体型、大功率的设备，应用的场合和范围受到很大限制，不能满足便携式应用的需要。另外，由于射频辐射的电磁能量可深入皮下组织，容易使治疗部位的组织因能量积聚导致温度过高而受到损伤，而已有的射频治疗设备都不能在治疗时实时采集治疗部位的温度，因而不能根据温度来调整能量的输出，只能采取物理降温、中断治疗或根据经验调整能量等方式来防止治疗部位受到高温损伤，而这些方式不是降低了设备的使用效率就是降低了用户的体验感和依从性，从而都会影响最终的治疗效果。Radio frequency therapy equipment is a kind of physical therapy equipment that acts on human tissue through radio frequency electromagnetic field to produce thermal effect and non-thermal effect, so as to achieve the purpose of treatment. After amplification and coupling detection, it is transmitted to the radio frequency radiator to radiate out to form an electromagnetic field. At present, radiofrequency treatment equipment is mainly used for thermal effect. Since the thermal effect generated by radiofrequency energy can produce deep diathermy on biological tissues, it has been widely used in clinical practice. However, the existing radio frequency treatment equipment generally uses a tube oscillator as the power source, the radiator is composed of pairs of capacitive electrode plates, and the power is conducted between the power source and the radiator through coaxial cables. Therefore, it is a large-scale, high-power device that can only be used in fixed occasions. The application occasion and scope are greatly limited, and it cannot meet the needs of portable applications. In addition, because the electromagnetic energy of radio frequency radiation can penetrate deep into the subcutaneous tissue, it is easy to cause damage to the tissue at the treatment site due to the accumulation of energy and cause excessive temperature. Existing radio frequency treatment equipment cannot collect the temperature of the treatment site in real time during treatment. To adjust the output of energy according to the temperature, only physical cooling, interruption of treatment, or adjustment of energy based on experience can be used to prevent the treatment site from being damaged by high temperature. These methods either reduce the efficiency of the device or reduce the user's sense of experience and compliance. sex, which will affect the final treatment effect.
