典型智能化心臟復蘇儀系統(tǒng)分析3AnalysisofrentingsystemoftypicalpublicelectricscooterTC"3StudyonSingle-tubeandDouble-tubeFly-backConverter"\l13.1主流產(chǎn)品結(jié)構(gòu)功能分析(MainstreamproductstructurefunctionanalysisTC"3.1IntroductiontoFlybackConverter"\l2)分析現(xiàn)有的心臟復蘇儀系統(tǒng)中的硬件主要部件與功能。包括了工具本身，呼吸機，以及心臟復蘇儀器。作為日常醫(yī)療救助工具，必須要有完善的系統(tǒng)才能保證運行。3.2主流產(chǎn)品造型分析(MainstreamproductmodelinganalysisTC"3.2Introductiontosingle-endedflybackconverter"\l2)心肺復蘇機心臟復蘇儀外形分析：可以看到，目前在心肺復蘇機和心臟復蘇儀外形上趨于相似，不同的結(jié)構(gòu)都是一種形式。，線條處理中規(guī)中矩，不具有時尚元素。作為醫(yī)療器械，是日常家庭救助的一部分，同樣傳遞了醫(yī)療器械的風貌，而現(xiàn)有的醫(yī)療產(chǎn)品顯然在造型上歸于普通。色彩分析：平常的心肺復蘇機通常采取單一紅色為整體色彩，以此凸顯醫(yī)療救助的理念。但是，這樣的設計往往忽略了不同性別不同人群對于色彩的偏好?？傮w來講造型過于普通。上面都是主流市場運行的心臟復蘇儀系統(tǒng)中的產(chǎn)品，也有走在潮流探索方向的相關設計。比如這款心臟復蘇儀，我們可以看到它整體比較輕巧，色彩附有科技感，整體線條流暢，造型簡約，非常具有時尚感。盡管它是醫(yī)療器械，但它對外形設計的思考確實是目前所有醫(yī)療產(chǎn)品所欠缺的。我們在進行智能化心臟復蘇儀的設計時，不僅要考慮到結(jié)構(gòu)的可行性，也要在這種結(jié)構(gòu)下考慮外形線條，材料之感，色彩搭配等方面。3.3材料與電池分析(MaterialsandbatteryanalysisTC"3.3Introductionofdouble-tubeflybackconverter"\l2)材料：成為批量化生產(chǎn)的醫(yī)療器械，需要選取合適的材料。通過資料查詢發(fā)現(xiàn)現(xiàn)有市場上材料一般是低碳鋼和林合金材料。由于低碳鋼材料加工方便，造價低廉，是目前使用最普遍的材料。鋁合金材料密度小質(zhì)量輕，但是造價較高，現(xiàn)在主要用于較高檔的其他產(chǎn)品上。當前，還有新型碳纖維材料也能作為材料，它有強度大、模量高、密度低、線膨脹系數(shù)小等一系列優(yōu)點，但由于價格特別高，目前尚無可能投入批量化生產(chǎn)。表3-3各類電池優(yōu)缺點分析Table3-3Analysisofmeritsanddemeritsofvariousbatteries當前，主流的電池主要分為鉛酸電池，鎳氫電池，鋰電池三大類。綜合分析各類電池的優(yōu)缺點，目前的電子產(chǎn)品一般用鋰電池?？偟膩碚f，蓄電池的選用應綜合考慮電池的容量、尺寸、重量、可靠性對心臟復蘇儀的結(jié)構(gòu)、舒適性、安全性、方便性的影響，同時要考慮電池的經(jīng)濟性以滿足推廣和減少成本的需要。3.4適用于智能化系統(tǒng)的醫(yī)療救助工具(Medicalaidtoolsforintelligentsystem)智能化醫(yī)療器械產(chǎn)業(yè)是醫(yī)療電子行業(yè)的重要分支，它是集聲、光、電為一體的多學科交叉型、技術(shù)知識密集型、高附加值的高新技術(shù)產(chǎn)業(yè)，具有廣闊的發(fā)展空間。智能化醫(yī)療器械產(chǎn)業(yè)也是電子信息產(chǎn)業(yè)的一個重要分支，計算機在醫(yī)學上的應用是提升醫(yī)療電子行業(yè)向智能化醫(yī)療器械邁進的高技術(shù)關聯(lián)產(chǎn)業(yè)鏈核心。我國是醫(yī)療器械需求大國，至2005年底，我國有15500家縣級以上醫(yī)療機構(gòu)，醫(yī)療器械已形成年銷接近600億元人民幣的市場;并且每年以15%--20%的速度增長。據(jù)不完全統(tǒng)計，僅2003年進口額為33億美元，2005年進口額接近50億美元。醫(yī)療機構(gòu)購置醫(yī)療設備費用的90%以上用于購買國外產(chǎn)品，這些基本都是屬于智能化醫(yī)療器械。我國現(xiàn)有自行研發(fā)生產(chǎn)的智能化醫(yī)療器械相當于發(fā)達國家15年前水平。21世紀初是我國全民生活水準迅速提高的時期，也是拉動發(fā)展醫(yī)療器械產(chǎn)業(yè)的關鍵時期。目前國內(nèi)醫(yī)療器械產(chǎn)業(yè)品牌甚少，以生產(chǎn)中低檔水平醫(yī)療器械為主，企業(yè)在窘境中徘徊，缺乏國際競爭力。大力扶植發(fā)展智能化醫(yī)療器械是醫(yī)療器械產(chǎn)業(yè)發(fā)展的戰(zhàn)略選擇。醫(yī)療器械產(chǎn)業(yè)與制藥產(chǎn)業(yè)被譽為醫(yī)療產(chǎn)業(yè)界的兩大“長青樹”，在國外這兩顆“長青樹”產(chǎn)業(yè)規(guī)模相當。而我國醫(yī)療器械產(chǎn)業(yè)的規(guī)模僅是制藥業(yè)的1/5--1/4,發(fā)展極不平衡。積極加大智能化醫(yī)療器械產(chǎn)業(yè)的投資力度，具有廣闊的發(fā)展空間?，F(xiàn)狀剖析行政規(guī)署制度制約了中國醫(yī)療器械產(chǎn)業(yè)的發(fā)展從國家體制的行業(yè)管理分類來看，該行業(yè)歸口為國家食品藥品監(jiān)督管理局醫(yī)療器械司，省市級科委行政設定為“生物制藥和環(huán)保類”。行政主管官員有開發(fā)生產(chǎn)醫(yī)療器械經(jīng)歷的人員甚少，而醫(yī)療器械規(guī)格品種門類繁多，涉及知識領域廣泛，單一人員難以全面深刻了解全貌。國家科技部每年度計劃項目的分類目錄中，該行業(yè)劃歸在生物制藥、衛(wèi)生、藥品等類別下，最近才劃分到生物工程門類之下。以往該行業(yè)統(tǒng)計數(shù)據(jù)難以歸類分析，隱身在藥品行業(yè)的陰影之后。由于醫(yī)療器械品種繁多，分類包括“聲、光、機、電、紡織、紡織、化工、材料”等多種單一門類或幾種門類的交叉構(gòu)成，這在國內(nèi)行政管理方面造成很大困難。比如，在早期的中小企業(yè)發(fā)展基金評審中，醫(yī)療器械項目就難以找到相應的專家進行評議。在建國初期，國家百業(yè)待興，國家領導人年富力強，忙于國家的基本建設，很少考慮醫(yī)療領域。在國家計劃經(jīng)濟時代，也無暇顧及醫(yī)療器械行業(yè)。在國家經(jīng)濟改革時代，在我國這個新興產(chǎn)業(yè)少人問津。由于按照國內(nèi)行政管理的特點，造成了現(xiàn)在醫(yī)療器械行業(yè)存在重管理輕扶植的局面，使得我國醫(yī)療器械企業(yè)規(guī)模小，競爭力弱，長期在低水平和小規(guī)模狀況下徘徊。醫(yī)療器械行業(yè)協(xié)會行業(yè)指導能力和影響力弱，在關貿(mào)總協(xié)定的談判條件中，屬于被忽略的地位，重視的比重遠遠小于輕工業(yè)中的“紡織品和鞋業(yè)”。醫(yī)療機構(gòu)的現(xiàn)有采購傾向影響我國醫(yī)療器械產(chǎn)業(yè)發(fā)展長期以來，衛(wèi)生部門規(guī)定的醫(yī)療儀器收費標準變相鼓勵醫(yī)療機構(gòu)進口國外醫(yī)療器械，對國外的企業(yè)以“超國民待遇”，這種消極觀念影響長期難以消除。比如監(jiān)護儀收費標準是，使用國內(nèi)企業(yè)生產(chǎn)的監(jiān)護儀每小時收費3元，而使用國外企業(yè)生產(chǎn)的監(jiān)護儀每小時收費6元。有些醫(yī)療機構(gòu)在醫(yī)療儀器采購中，直接或間接排斥國內(nèi)企業(yè)生產(chǎn)產(chǎn)品，以數(shù)倍于國外當?shù)貎r格購回醫(yī)用儀器。這些現(xiàn)象嚴重影響我國醫(yī)療器械產(chǎn)業(yè)發(fā)展。早在1994年我國的專家就呼吁“用購買兩臺CT的費用就可以研制出一臺CT，再用10臺購買CT的費用就可以生產(chǎn)出50臺CT”，但這些呼吁得不到有關部門的任何支持。美國早已在制定的《購買美國產(chǎn)品法》中明確規(guī)定，在政府采購活動中，除非有關機構(gòu)或部門的負責人斷定，本國所供應的貨物或服務的價格“不合理”(美國中小企業(yè)產(chǎn)品的報價只要不超過外國供應商報價的12%即為合理)，或者購買它們將不符合美國的公共利益，就必須購買本國的貨物或服務。美國政府采購支持國貨，促進了美國企業(yè)的發(fā)展。遺憾的是，我國至今尚未制定相應的購買本國貨物或服務的保護措施和法律法規(guī)。國外企業(yè)的壟斷性銷售直接阻礙我國醫(yī)療器械產(chǎn)業(yè)發(fā)展自1992年蘇聯(lián)解體，世界“冷戰(zhàn)”結(jié)束后。國外大型軍工企業(yè)瞄準醫(yī)療器械產(chǎn)業(yè)這一“長青樹”，紛紛將生產(chǎn)軍火的技術(shù)用于生產(chǎn)醫(yī)療器械，使得醫(yī)療器械尤其是智能化的醫(yī)療器械日新月異。國際醫(yī)療設備大型企業(yè)間并購風起云涌，呈快速上升趨勢。這些“航母級”的國外或外資企業(yè)直接與“舢板級”的國內(nèi)企業(yè)在中國醫(yī)療市場上角逐，情形可想而知。建立智能化醫(yī)療器械產(chǎn)業(yè)園，造就中國的“航母”級企業(yè)智能化醫(yī)療器械是新興技術(shù)產(chǎn)業(yè)，增長速度遠遠大于其它傳統(tǒng)行業(yè)的發(fā)展速度。為扶植這一新型產(chǎn)業(yè)，必須制定相應的保護措施和法律法規(guī)，保障這一新興技術(shù)產(chǎn)業(yè)的發(fā)育、成熟、壯大。由智能化醫(yī)療器械行業(yè)內(nèi)科學家作為“行業(yè)旗幟型”的科技帶頭人;以行業(yè)學會為依托，全國大專院校、科研院所和大型企業(yè)研發(fā)機構(gòu)直接參加，以研發(fā)轉(zhuǎn)化基地為載體，建立中國智能化醫(yī)療器械研發(fā)中心和產(chǎn)業(yè)化基地，即智能化醫(yī)療器械產(chǎn)業(yè)園。它可實現(xiàn)四大功能:科技攻關的平臺、高技術(shù)產(chǎn)業(yè)化基地、技術(shù)交流培訓的載體和對外合作交流的窗口。積極開展研究和解決產(chǎn)業(yè)面臨的共性問題培養(yǎng)產(chǎn)業(yè)急需的各類人才;不拘一格募集智能化醫(yī)療器械產(chǎn)業(yè)急需人才。如技術(shù)前沿人才和知識產(chǎn)權(quán)發(fā)展戰(zhàn)略人才，“行業(yè)旗幟型”的科學家和管理人才等;開展智能化醫(yī)療器械產(chǎn)業(yè)內(nèi)外的人才和設備資源整合和優(yōu)勢互補的合作;利用產(chǎn)業(yè)園的研究成果轉(zhuǎn)讓資金和接產(chǎn)研究成果的大型企業(yè)生產(chǎn)資金，開始滾動運營，形成研究成果產(chǎn)業(yè)化。聯(lián)合金融機構(gòu)和財團，建立中國智能化醫(yī)療器械產(chǎn)業(yè)發(fā)展基金;聯(lián)合各部委辦，結(jié)合“研、產(chǎn)”一體的優(yōu)勢，為市場大量急需或滿足人們新的醫(yī)療模式急需的產(chǎn)品研制提供強有力的技術(shù)支持;建立行業(yè)指導協(xié)會，彌補國家行政管理的弱區(qū)。融入國際化行業(yè)機構(gòu)和國際標準化組織，制訂發(fā)展所需的國內(nèi)產(chǎn)業(yè)標準;建立開放式軟硬件試驗室，采用共同購置或租賃，共享版權(quán)，分時使用的原則，解決產(chǎn)業(yè)園內(nèi)外相關單位軟件版權(quán)使用合法性問題，促進產(chǎn)業(yè)上下游單位和產(chǎn)品間的銜接;實行在智能化醫(yī)療器械產(chǎn)業(yè)園內(nèi)首選的單位間合作的創(chuàng)新模式、協(xié)調(diào)各單位間的相互關系、實現(xiàn)信息和技術(shù)的交流與成果共享。通過創(chuàng)新的合作模式，組建智能化醫(yī)療器械集團。統(tǒng)一協(xié)調(diào)、按行業(yè)標準指導、按分類實行管理、按專業(yè)制定規(guī)劃、按產(chǎn)品充實發(fā)展、宏觀與微觀相結(jié)合，經(jīng)過研發(fā)轉(zhuǎn)化基地的發(fā)展運營，實現(xiàn)國內(nèi)兩種優(yōu)勢、內(nèi)外兩種機制、科技兩種技術(shù)、營銷兩種市場的戰(zhàn)略格局。形成新產(chǎn)業(yè)利潤的高增長點，造就中國智能化醫(yī)療器械產(chǎn)業(yè)的“航母”級企業(yè)。這是充滿生機活力的科技發(fā)展新思路。4目標用戶研究4TargetuserresearchTC"4Simulationcircuitdesignandparametercalculation"\l14.1用戶人群劃分和確立(UserpopulationdelineationandestablishmentTC"4.1Designrequirements"\l2)我們的目標人群大多是心臟病患者。在調(diào)研階段，我們了解了各類各個醫(yī)療器械的使用人群，職業(yè)和收入?？梢园l(fā)現(xiàn)，使用醫(yī)療器械的人群主要集中在老年人群體。他們一般屬于中產(chǎn)階級或低收入甚至無收入人群，他們是收入較低但又思想頑固的中老年人。為此，選取中老年人群體進行深入研究與分析。4.2用戶訪談分析(UserinterviewanalysisTC"4.2Overalldesign"\l2)先選取這些人群中的幾個人進行用戶訪談。用戶訪談在這個階段能獲得目標人群對現(xiàn)有產(chǎn)品的評價，獲取產(chǎn)品使用情境的信息[[1]丁玉蘭.人機工程學(第四版).北京：北京理工大學出版社，2011[[1]丁玉蘭.人機工程學(第四版).北京：北京理工大學出版社，2011[2]宋珈．應用Thumper心肺復蘇儀搶救心跳呼吸驟?；颊叩呐R床觀察[J]．吉林醫(yī)學，2012，33(25)：5397-5398．[3]王原平，胡鳳林，陳雪珍，等．心肺復蘇儀胸外心臟按壓對心肺復蘇成功的影響[J]．嶺南急診醫(yī)學雜志，2009，8(1)：13—15．[4]李向云．Thumper1007型心肺復蘇儀在院前急救中的應用58例分析[J]_中國誤診學雜志，2012，12(15)：4021—4021．[5]李海娟，黃雪梅，莫景書．薩勃心肺復蘇儀進行心肺復蘇的臨床應用及效果觀察[J]．中國醫(yī)藥指南，2012,10(11)：139—139．[6]英義．2005年和2010年不同心肺復蘇指南在院前急救中的應用[J]．中國煤炭工業(yè)醫(yī)學雜志，2012，15(6)：112．[7]鄭偉華，謝鋼，楊偉東，等．自動體外除顫在院前搶救心臟驟停中的應用[J]．中國全科醫(yī)學，2002，22(9)：256．[8]江敏，吳卸仙．院前急救對急性出血性腦卒中患者預后的影響[J]．中國鄉(xiāng)村醫(yī)藥，2011，18(7)：53．[9]陳勇，白祥軍．Autopulse無創(chuàng)自動心肺復蘇系統(tǒng)在院前急救中的使用[J]．臨床急診雜志，2011，12(3)：148．[10]張念清．心臟驟停心肺復蘇8O例臨床分析[A]．江西省第七次中西醫(yī)結(jié)合危重病、急救醫(yī)學學術(shù)研討會論文集[c]．2011．[11]張會文，李杰，劉巧玲，等．氣管插管與口咽通氣管在院前急救中的應用比較[J]．齊魯護理雜志，2011，16(5)：132．[12]張國秀，謝小娟，王志峰，等．干預前后死亡疾病譜分析[J]．醫(yī)藥論壇雜志，2011，32(9)：228[13]付曉莉，趙云.格式塔心理學在產(chǎn)品外觀設計中的應用研究[J].工業(yè)設計，2020（2）：86-87翻譯部分英文原文1.1DesignbackgroundTC"1.1DevelopmentandCurrentSituationofSwitchingPowerSupply"\l2Thereport,titled"statusofcardiovascularhealthinChineseadults,"isbasedonthecardiovascularhealthdataofmorethan96000Chinesepeopleovertheageof20.ThestudyusestheAmericanHeartAssociationstandard,whichdividescardiovascularhealthintobehavioralhealthandphysicalhealth.Behavioralhealthincludesnon-smoking,normalbodymassindex,physicalexercisestandardanddiethealth.Physicalhealthindicatorsincludenon-smoking,normalbloodlipid,normalbloodpressureandnormalbloodglucose.(smokinghappenedtwice).ThefinaldatashowsthatinChina,13.5%ofthepeoplehavefourindicatorsofphysicalhealth,andonly7‰ofthepeoplehavefourbehavioralhealthindicators,whilethenumberofpeoplewhomeetallthesevenhealthindicatorsisdownto2‰.Theresearchersalsodividedthesevenhealthindicatorsintothreelevels:ideal,mediumandlow.Amongthem,thepoorcardiovascularhealthreached3/4,themediumcardiovascularhealthaccountedforlessthan1/4,andtheidealwasevenmorenegligible.Theglobalburdenofdiseasereport2013,publishedbythelancet,theworld'sleadingjournalofmedicine,assessesdeathsin188countriesbetween1990and2013,undertheguidanceofaninternationalconsortiumofresearchersledbytheInstituteforhealthindicatorsandassessment(IHME),UniversityofWashington.Accordingtothereport,thethreedeadliestdiseasesinChinaarestroke,coronaryheartdiseaseandchronicobstructivepulmonarydisease,whichaccountedfor46%ofalldeathsin2013.Accordingtothedefinitionofwho,cardiovasculardiseaseiscausedbyheartandvasculardiseases,includingcoronaryheartdisease,stroke,hypertension,heartfailure,etc.Inotherwords,cardiovasculardiseasesaccountfortwoofChina'sthreedeadliesthealthkillers.1.2Designsignificanceandvalue(Designsignificanceandvalue)（1）ReduceheartdiseasemortalityThenumberofcardiovasculardiseasesinChinahasreached290million,thatistosay,2outofevery10adultshavecardiovasculardiseases,andabout3.5millionpeopledieofcardiovasculardiseaseseveryyear,whichisequivalentto1persondieofcardiovasculardiseasesevery10seconds.AnotherclinicalstudyconductedbytheNationalCenterforcardiovasculardiseaseandFuwaicardiovascularhospitalshowsthatthenumberofpatientswithcardiovasculardiseaseinChinahasmorethanquadrupledinthedecadefrom2001to2010.TheintelligentCPRdevicecaneffectivelyandtimelyhelpthepatientswithheartdiseasetowintimewhentheyareill.TheintelligentCPRdevicecanbeusedbythepatientsthemselvesorassistedbysomeonenearbytoalleviatethepainofthepatientswithheartdiseaseandsupportthearrivaloftheambulance.Atthesametime,theproductcanalsobeusedasanemergencyequipmentforthefamiliesofthepatientswithheartdisease.（2）IntelligentdevelopmentofbigdatasharingItcanprovidecontinuouspressingemergencymodewithpressingfrequencynolessthan100times/minforpatientswithcardiacarrestcausedbyvariousreasonsindifferentoccasions,anditcanalsoprovidecardiacresuscitationemergencymodew
