发布时间：2018-11-06 20:04
【摘要】：强脉冲光(IPL)治疗仪是一种现代医疗器械,它采用了非剥脱、非接触的方式治疗各种皮肤疾病,主要是依靠低能量、强脉冲光照射皮肤病损组织,使其发生选择性的光热解作用,达到治疗目的。 市场上IPL治疗仪采用更多的是单片机嵌入式系统,例如某公司产品强脉冲光子仪器,采用的是以ATMAGE128为核心的控制系统,这套系统由于采用了只具有128K字节可编程Flash的8位微处理器,极大的限制了控制功能的多样性,而且无法在后续的开发改进中增加应用接口。同时,由于各种型号的仪器对控制系统的要求大致相同,显然,重复开发是极其浪费资源的。 虽然IPL等仪器设备已经在社会上得到广泛应用,但是对于IPL对人体皮肤的作用机理还不十分清楚,对于光的各种参数,包括波长、光谱、脉宽、脉冲间隔、光斑大小、重复频率、功率和能量等,如何影响着治疗的效果还缺乏定量的数据。其中对强脉冲光信号的快速、有效、实时测量的缺乏是影响定量研究的重要原因。 本论文的工作是采用以ARM为核心的嵌入式系统,并搭建Linux操作系统平台,在此基础上开发基于Qt库的用户操作界面,产生IPL所需的时钟控制信号。利用ARM对IPL输出光脉冲信号进行测量,对输出光脉冲的个数和脉冲宽度进行实时监测。本论文对强脉冲的光谱测量进行理论分析、电路设计、软件设计以及调试,其硬件和软件都已经调试通过,初步测量了强脉冲光的光谱分布。
[Abstract]:Strong pulse light (IPL) is a modern medical instrument, it uses non-stripping, non-contact treatment of a variety of skin diseases, mainly rely on low energy, strong pulse light irradiation of skin damage tissue, Make it produce selective photopyrolysis to achieve the purpose of treatment. In the market, the IPL therapeutic instrument adopts more embedded single-chip microcomputer system, such as the strong pulse photonic instrument produced by a company, and the control system with ATMAGE128 as the core. Due to the use of 8-bit microprocessor with only 128K byte programmable Flash, this system greatly limits the diversity of control functions, and can not add the application interface in the subsequent development and improvement. At the same time, the requirements of various types of instruments for the control system are roughly the same, it is obvious that repeated development is a waste of resources. Although IPL and other instruments have been widely used in society, the mechanism of IPL's action on human skin is not very clear. For the various parameters of light, including wavelength, spectrum, pulse width, pulse interval, light spot size, There is a lack of quantitative data on how repetition rates, power, and energy affect the outcome of the treatment. Among them, the lack of fast, effective and real-time measurement is an important factor affecting the quantitative research. The work of this paper is to use the embedded system with ARM as the core, and build the Linux operating system platform. On this basis, the user interface based on Qt library is developed to generate the clock control signal needed by IPL. The output light pulse signal of IPL is measured by ARM, and the number and width of output light pulse are monitored in real time. In this paper, theoretical analysis, circuit design, software design and debugging have been carried out for the spectral measurement of strong pulses. The hardware and software have been debugged and the spectral distribution of intense pulses has been preliminarily measured.
