【摘要】：強脈沖光(IPL)治療儀是一種現(xiàn)代醫(yī)療器械,它采用了非剝脫、非接觸的方式治療各種皮膚疾病,主要是依靠低能量、強脈沖光照射皮膚病損組織,使其發(fā)生選擇性的光熱解作用,達到治療目的。 市場上IPL治療儀采用更多的是單片機嵌入式系統(tǒng),例如某公司產(chǎn)品強脈沖光子儀器,采用的是以ATMAGE128為核心的控制系統(tǒng),這套系統(tǒng)由于采用了只具有128K字節(jié)可編程Flash的8位微處理器,極大的限制了控制功能的多樣性,而且無法在后續(xù)的開發(fā)改進中增加應(yīng)用接口。同時,由于各種型號的儀器對控制系統(tǒng)的要求大致相同,顯然,重復開發(fā)是極其浪費資源的。 雖然IPL等儀器設(shè)備已經(jīng)在社會上得到廣泛應(yīng)用,但是對于IPL對人體皮膚的作用機理還不十分清楚,對于光的各種參數(shù),包括波長、光譜、脈寬、脈沖間隔、光斑大小、重復頻率、功率和能量等,如何影響著治療的效果還缺乏定量的數(shù)據(jù)。其中對強脈沖光信號的快速、有效、實時測量的缺乏是影響定量研究的重要原因。 本論文的工作是采用以ARM為核心的嵌入式系統(tǒng),并搭建Linux操作系統(tǒng)平臺,在此基礎(chǔ)上開發(fā)基于Qt庫的用戶操作界面,產(chǎn)生IPL所需的時鐘控制信號。利用ARM對IPL輸出光脈沖信號進行測量,對輸出光脈沖的個數(shù)和脈沖寬度進行實時監(jiān)測。本論文對強脈沖的光譜測量進行理論分析、電路設(shè)計、軟件設(shè)計以及調(diào)試,其硬件和軟件都已經(jīng)調(diào)試通過,初步測量了強脈沖光的光譜分布。
[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.
