【摘要】：蒸汽滅菌技術(shù)是目前全世界公認的最可靠的滅菌技術(shù)之一,大量地應(yīng)用在工農(nóng)業(yè)和醫(yī)療衛(wèi)生各領(lǐng)域。蒸汽滅菌具有較高的溫度,可靠的滅菌效果,易于控制和操作,因此在目前盡管各種滅菌技術(shù)不斷飛速進步,但這種廣泛使用的滅菌方法在消毒滅菌領(lǐng)域仍占有重要地位。蒸汽滅菌器在國內(nèi)大中型醫(yī)療機構(gòu)使用較多,必須通過各種方法來保證蒸汽滅菌器的滅菌效果。目前在國內(nèi)小型蒸汽滅菌器性能要求主要執(zhí)行醫(yī)藥標準《小型蒸汽滅菌器自動控制型》（YY0646－2008），主要規(guī)定了小型自動控制蒸汽滅菌器的性能要求和試驗方法。由于YY0646－2008等標準增加了飽和蒸汽溫度和時間要求，以及關(guān)于使用各種負載的要求，有必要研制符合標準要求的檢測設(shè)備。國內(nèi)外主要采用有線傳感器直接連接方式，通過蒸汽滅菌設(shè)備的專門接口直接穿線將傳感器與外部測量儀器連接起來，進行信號采集。由于標準中規(guī)定至少同時進行多路溫度測量，經(jīng)常會因為一根信號傳輸線出問題或一個傳感器損壞而必須更換整個傳感器模塊，既麻煩又不經(jīng)濟。為此，很有必要發(fā)展新的測量方法與檢測設(shè)備，使高壓蒸汽滅菌設(shè)備的溫度值與壓力值測量變得簡便、準確、高效。 本文開展蒸汽滅菌器檢測設(shè)備的研究，發(fā)展一種可以使用有線或無線方式的多通道溫度壓力測量技術(shù)，選擇Pt1000溫度傳感器和Keller Series35XHT高溫壓力傳感器，并通過軟件算法進行溫度壓力測量誤差修正處理，按照行業(yè)標準的方法要求，進行檢測設(shè)備的研究和驗證工作。該檢測設(shè)備具有測量通道多（8路溫度測量，，單路壓力測量）、量程大（溫度測量范圍0℃～150℃，壓力測量范圍-100kPa～400kPa）、環(huán)境適應(yīng)性強（高壓蒸汽滅菌環(huán)境）、精度較高（溫度0.5℃,壓力0.1%）、傳感器易于更換、實時數(shù)據(jù)曲線等特點，能很好的完成對高壓蒸汽滅菌設(shè)備內(nèi)部環(huán)境溫度壓力數(shù)值的采集工作。 本文所設(shè)計的計算機數(shù)據(jù)處理軟件可以通過USB通訊接口讀取溫度壓力測試主機中的溫度數(shù)據(jù)和壓力數(shù)據(jù)，并進行誤差修正處理，以報表和曲線圖的形式導(dǎo)出，便于統(tǒng)計和查閱，而且實現(xiàn)了對數(shù)據(jù)的在線實時處理功能。
[Abstract]:Steam sterilization is one of the most reliable sterilization technologies in the world, which is widely used in industry, agriculture and medical and health fields. Steam sterilization has high temperature, reliable sterilization effect, easy to control and operate, so it still occupies an important position in the field of disinfection and sterilization in spite of the rapid progress of various sterilization technologies at present, but this widely used sterilization method still occupies an important position in the field of disinfection and sterilization. Steam sterilizer is widely used in large and medium medical institutions in China. The sterilization effect of steam sterilizer must be ensured by various methods. At present, the performance requirement of small steam sterilizer in China is mainly carried out according to the medical standard < automatic control type of small steam sterilizer > YY0646-2008, which mainly stipulates the performance requirements and test methods of small automatic control steam sterilizer. Since YY0646-2008 and other standards have increased the temperature and time requirements of saturated steam, and the requirements for the use of various loads, it is necessary to develop a testing equipment that meets the requirements of the standard. The wire sensor is mainly used to connect directly at home and abroad, and the sensor is connected with the external measuring instrument directly through the special interface of the steam sterilizing equipment, and the signal is collected. Due to the requirement of multichannel temperature measurement at least simultaneously in the standard, the whole sensor module must be replaced because of the problem of one signal transmission line or the damage of one sensor, which is both troublesome and uneconomical. Therefore, it is necessary to develop new measuring methods and equipment to make the measurement of temperature and pressure of high pressure steam sterilizing equipment simple, accurate and efficient. In this paper, the testing equipment of steam sterilizer is studied, and a multi-channel temperature and pressure measurement technology, which can use wired or wireless mode, is developed, and Pt1000 temperature sensor and Keller Series35XHT high temperature pressure sensor are selected. The error correction of temperature and pressure measurement is carried out by software algorithm, and the testing equipment is researched and verified according to the requirements of industry standard. The equipment is equipped with multi-channel and 8-channel temperature measurement, single channel pressure measurement, large measuring range (temperature measurement range of 0 鈩
