仍為0V，基本上可排除D1板。通電時用手電光照射D2板J1，測量D2板X7、X9之間電壓，可由，說明控制柵極電壓的D2板應是好的。測量D3板上給UFIL板供電的，此電壓是對的，但X9、X10之間無。可以肯定UFIL板有問題。拆下UHL板，檢查發(fā)現(xiàn)V113、V209、V115都已擊穿。V113(MR752)為一個6A、200V的快速恢復整流管，市場上沒有，用一個16A、200V的快復管替換。V209(BZV86-1V4)為、，V115(ZPD11ITT)沒找到替換元件，于是訂了一塊UFIL板。新UFIL板到貨后，裝上通電，此時，球管燈絲亮，且測量燈絲電壓為，但是故障現(xiàn)象依舊，PSCU板上reset紅燈仍然不滅。檢查D2板上J2(T1523)不亮，所以往PSCU板上FIL-MEG沒送來光電信號，HVPS仍不能正常送高壓。檢修D2板上J2，已壞，從舊的D2板上取下J2換上后，再通電，F(xiàn)IL-MEG光信號正常了，但是PSCU板上reset紅燈仍然不滅。進一步分析圖紙，發(fā)現(xiàn)要HVPS正常上高壓，需要同時具備燈絲信號、PALl信號及INTL信號。而INTL信號是從E11板(DRIVER板)通過RFPA的、。打開RFPA頂蓋，檢查E11板，發(fā)現(xiàn)其綠色指示燈不亮，說明E11也有問題。拆下E11板后V23127-B0002-A201的繼電器已燒斷，在網上查到其為一個12V繼電器。但市場上無法買到插腳位置與其一樣的12V繼電器。儋州AESCULAP蛇牌PV430攝像主機維修并要有一定的醫(yī)學知識，這是維修彩超不可缺少的必備條件。</p><div

隨著醫(yī)療衛(wèi)生事業(yè)的飛速發(fā)展，大量高科技電子設備不斷涌現(xiàn)，是技術密集、知識密集、資金密集的產品、而血液透析機無論是國產還是進口的設備,（進口占比例大），均屬高科技機電一體化醫(yī)電產品,并且采用微機技術.自檢報警功能多,操作相對復雜,而不同產地(不同型號其操作方法和日常維護方法也不同。另外,目前大中型血液透析中心或小型血液透析室所配備的血液透析機尚不能完全滿足實際所需,大都無相應的備用機,在病人多的情況下,一般每天每臺設備要透析二例甚至達到三例患者,工作時間長,時間長達(10-15小時),操作人員思想負擔較重,所以工作中常常出現(xiàn)因操作不當而造成人為故障。比如常見有關按鍵或旋鈕調節(jié)不當,血路或液體管路夾破裂,透析液的濃縮液配比不符合要求,光學傳感器不清潔等因素而導致機器經常出現(xiàn)常規(guī)的報警,因為外界條件不符合機器所要求,誤認為機器出現(xiàn)故障,使整機不能及時進入正常透析程序從而影響整個透析計劃的順利進行,同時也給患者帶來了思想負擔,以及對機器產生恐懼感。大型醫(yī)療設備涉及多種學科和專業(yè),如醫(yī)學、電子、機械、光學、自動控制、計算機、信息圖像處理、生物學等,醫(yī)學工程專業(yè)已成為一門綜合性學科,大型設備本身龐大復雜,維修靠一個人很難完成。</p><p> 所以又訂E11板。從這一連串板子的問題分析，懷疑很有可能D3板有問題。因為UFIL板和E11板都由D3板供電。檢查發(fā)現(xiàn)D3板上N1(78H05)已壞，給球管記時器的電壓為0V，故記時器不走，雖然這不是此，次故障的影響因素，還是訂了一塊D3板。當K11(DRIVER)板與D3板到貨后，先裝上E11板，給RFPA通220V交流電后，E11板上綠色指示燈亮。接上HVPS后開機，D3板位置發(fā)出叭的一聲，于是便馬上關掉HVPS。檢查剛換的UHL板、E11板及D2板，都還好。將D3板拆下，與新的D3板對照，發(fā)現(xiàn)V2整流塊不好。換上新的D3板后再接上HVPS通電，一切正常。3小結這次故障一次壞了4塊電路板，是比較少見的。究其原因應該是由于D3板有問題而引起。后面，調節(jié)D2板上R2，將柵極電壓以及管電流調整好，又做了RFcharacter曲線，至此，機器恢復正常使用。各個線圈做水模測試，性噪比均超過標準要求。檢修人員不要用手接觸電路板上的元件，當必須接觸時，要帶好靜電手鐲或靜電指環(huán)。</p><div

我院的NIPRONDX-1血濾機報“E224充填系統(tǒng)異?！惫收嫌幸欢螘r間了。偶發(fā)，復位以后能用一段時間，有時候甚至幾天也不報一次。期間檢查了管路，過濾網，限流管等處，均無明顯的堵塞。很是頭疼。昨天下午，病人下機后，進行例行的水洗消毒時又出現(xiàn)此故障，而且復位后1、2分鐘馬上又報，這次看樣子是壞“透”了，應該能夠查到問題了。打開機器，檢查各個管路、過濾網、限流管等均無堵塞。后面把注意力放到了FS1和FS3這兩個流量傳感器上了。莫非是它們2個壞了？不多想了，拆下來再說。這個傳感器是磁性傳感器：里面有個鋼球，液體流動把鋼球推動到上部，無液體流動時鋼球落底，這樣后面的磁性元件就可以檢測是否有液體流動了。取下FS1，輕輕晃動，可以感到鋼球在里面滾動，并有輕微的撞擊的聲音，同時傳感器后面的指示燈隨著鋼球的滾動變換紅綠色。估計沒有問題，但為了以防萬一，還是拆開了，把里面的管路和鋼球清潔干凈裝回。取下FS3，用手一晃，居然沒有鋼球滾動撞擊的聲音，而且指示燈始終是紅色。心里一喜：看樣子就是它的問題了。拆開，并沒有發(fā)現(xiàn)堵塞物，只是鋼球表明不光亮了。也許是積鈣太多造成卡死吧？不管那么多了，把管路和鋼球清潔干凈裝回。在移動彩超時一定要盡量少其振動，平時彩超的腳輪的鎖開關一定要鎖住，以免機器滑動與其它物體碰撞。儋州AESCULAP蛇牌PV430攝像主機維修</p><p style="text-indent:25px">判斷機器是前端部分還是后端部分的故障原由而導致無法正常啟動；儋州AESCULAP蛇牌PV430攝像主機維修</p><p> 但也要注意考慮軟水系統(tǒng)或反滲機故障后的應急措施。四．濃縮液的配制問題：現(xiàn)代血液透析的供給是采用濃縮液與透析純水，反滲水，通過機器定容比例自動稀釋成血液透析液，這種配比液由電導度法指示出透析液內電解質總離子濃度，是保證透析安全的重要監(jiān)護指標之一，這種自動檢測監(jiān)護功能一般進口透析機均具備，而濃縮液的配制：多數(shù)是由人工根據配方自行配制而成。、通常透析液分為兩種(即醋酸鹽透析液和碳酸氫鹽透析液)做醋酸鹽透析，只配一種濃縮液，或做碳酸氫鹽透析液則需要配兩種濃縮液，任何一種濃縮液配制不當，均會引起不良后果，易使機器報警，若機器的電導率報警極限調得太寬或自檢功能失常時，就會給患者帶來如惡心、嘔吐、寒戰(zhàn)、血壓過高或過低等一系列透析反應，重則危及患者生命。另外：在實際工作中曾遇到幾臺機器同時因電導率過低或過高而報警，而不能正常透析，一般均屬濃縮液配制不合要求所致，因此：濃縮液的配制一定要嚴格按照配方配制，配制好的濃縮液比較好進行必要的檢測。另外不宜放置時間太長，以防止沉淀污染或變質使用時需過濾一下。五.血液透析機的維護與保養(yǎng)：血液透析機不同于其他常用電子儀器，它既有電路、又有水路、還有血路。儋州AESCULAP蛇牌PV430攝像主機維修</p><p
