目前，高頻電刀主要有三種形式：火花式振蕩電刀、電子管振蕩電刀、固體振蕩式電刀。火花式振蕩電刀是利用鎢合金電極間的空隙放電和LC振蕩回路組成衰減振蕩，它輸出的是間斷的高頻減幅波，如圖1-1-1a所示。電子管振蕩電刀通常由大功率高頻電子管與LC振蕩回路組成，振蕩比較穩(wěn)定。若振蕩管板極由直流供電，舟山WOFL5516攝像主機維修，則輸出如圖1-1-1b所示的連續(xù)高頻等幅波。若板極由50Hz交流電供給，舟山WOFL5516攝像主機維修，則輸出如圖1-1-1c所示的間斷的、幅度變化的高頻振蕩波。固體電刀則是利用晶體管、集成電路組成振蕩器和控制電路，其輸出的是連續(xù)波（圖1-1-1c）或間斷波（圖1-1-1d），或二者的組合波形。如果電子線路和元器件均正常，舟山WOFL5516攝像主機維修，另一原因就是機內(nèi)散熱系統(tǒng)出現(xiàn)問題，導致過流保護管跳閘，形成停機。舟山WOFL5516攝像主機維修</p><div

PB760(740)呼吸機的日常自檢有SST和EST，SST和EST中均有PEEP測試,很多時候,使用三五年以上的機器做測試時此PEEP測試會失敗,什么原因呢？ </p> <p> PEEP測試時，PEEP泵必須產(chǎn)生且維持預設的PEEP壓力水平（通常0-40cmh20），顯然如果有漏氣此測試也肯定通不過，目前我們排除漏氣的原因（因為LEAK TEST 在PEEP SYSTEM TEST之前），觀察發(fā)現(xiàn)，PEEP測試失敗時一般是壓力達到10-20CMH2O左右就打不上去了，故可判斷是因為PEEP泵沒有產(chǎn)生足夠的氣壓，PEEP系統(tǒng)由PEEP泵、緩沖腔、過濾器組成，觀察過濾器，會發(fā)現(xiàn)此過濾器很臟（內(nèi)部呈黑色），原因就在這里了，機器使用較長時間以后，此過濾器堵塞導致PEEP泵不能產(chǎn)生足夠的氣壓，從而導致PEEP測試失?。▏乐氐臅r候可能緩沖腔也會被堵塞）舟山WOFL5516攝像主機維修電源單元包括電源變壓器等，初級輸入220V，次級輸出高壓和低壓兩路。</p><div

任何儀器，無論其設計如何先進、完善，在使用過程中都避免不了因各種原因，產(chǎn)生這樣或那樣的故障，只是儀器的故障率不同而已。為保證儀器的正常工作，對儀器進行正常維護和及時修理是非常重要的。限于篇幅，本章只對醫(yī)學檢驗儀器的特點和維護要求、儀器維修應具備的條件、儀器出現(xiàn)故障的規(guī)律、種類和原因、儀器維修的程序和常用方法、醫(yī)學檢驗儀器的常用電子器件的檢查等內(nèi)容做些簡單介紹。首先節(jié)醫(yī)學檢驗儀器的特點和維護要求一、醫(yī)學檢驗儀器的特點醫(yī)學檢驗儀器是用于疾病診斷、疾病研究和藥分析的現(xiàn)代化實驗室儀器，其主要特點如下：1．結(jié)構(gòu)復雜醫(yī)學檢驗儀器多是集光、機、電于一體的儀器，使用器件種類繁多。尤其是隨著儀器自動化程度的提高和儀器的小型化，儀器功能的不斷增強，各種自動檢測、自動控制功能的增加，使儀器更加緊湊、結(jié)構(gòu)更加復雜。
