【摘要】:隨著我國醫(yī)療系統(tǒng)的不斷發(fā)展以及壯大,各種精密設(shè)備也越來越多,這對水質(zhì)的要求也就越來越高。在這種環(huán)境背景下,水處理系統(tǒng)在醫(yī)療系統(tǒng)中的應(yīng)用顯得尤為重要。在檢驗科、透析室、層流手術(shù)室、重癥監(jiān)護(hù)室等很多科室都需要安裝水處理系統(tǒng)以達(dá)到用水標(biāo)準(zhǔn)。水質(zhì)的嚴(yán)格控制直接關(guān)系到設(shè)備的正常運轉(zhuǎn),這也是避免設(shè)備高故障率以及多發(fā)醫(yī)療事故的必要措施。針對某醫(yī)院的層流手術(shù)室水處理系統(tǒng)為研究對象,重新設(shè)計了醫(yī)院層流手術(shù)室的水處理系統(tǒng)并進(jìn)行了測試。文中論述的系統(tǒng)結(jié)合了國內(nèi)外先進(jìn)水處理系統(tǒng)設(shè)計經(jīng)驗,根據(jù)實地環(huán)境以及用水標(biāo)準(zhǔn)采用反滲透技術(shù)進(jìn)行水處理。該層流手術(shù)室除了需要對原水進(jìn)行過濾脫鹽以外,還要求將水的電導(dǎo)率控制在要求范圍之內(nèi),該設(shè)計采用PLC與模糊控制相結(jié)合的方法,解決電導(dǎo)率控制建立準(zhǔn)確數(shù)學(xué)模型難的問題。在模糊控制算法上進(jìn)行了優(yōu)化與積分處理,使得電導(dǎo)率控制能夠適應(yīng)外界多因素的干擾,將電導(dǎo)率維持在要求范圍之內(nèi)。本文主要論述水處理系統(tǒng)的過濾方法、硬件設(shè)計、軟件設(shè)計、算法的優(yōu)化及分析等。該系統(tǒng)應(yīng)用在醫(yī)院層流手術(shù)室,電導(dǎo)率值基本穩(wěn)定,誤差維持在了規(guī)定范圍之內(nèi),達(dá)到了手術(shù)室用水標(biāo)準(zhǔn)。
[Abstract]:Along with our country's medical system continues to develop and grow, all kinds of precision equipment is also increasing, the water quality requirements are increasingly high. In this context, the application of water treatment system in the medical system is particularly important. In the laboratory, dialysis room, laminar flow operation room, ICU and other departments you need to install a water treatment system to achieve the water standard. Strict control of water quality is directly related to the normal operation of the equipment, which is the necessary measures to avoid the high rate of equipment failure and multiple medical accident. According to the water treatment system of a laminar flow operation room of the hospital as the research object, the redesign of the water treatment system of hospital and laminar flow operation room the test system is discussed in this paper. Combined with the domestic and foreign advanced water treatment system design experience, according to the field environment and water standards by reverse osmosis water treatment. The laminar flow operation room in addition to the filtration of raw water, but also requires the conductivity of water control in the range of requirements, the design method of using PLC combined with fuzzy control, established the accurate mathematical model of conductivity control difficult problem. In the fuzzy control algorithm are optimized and integrated, which can control the conductivity to adapt to the interference of external factors, will maintain the conductivity in the range of requirements. Filtering method, this paper mainly discusses the water treatment system hardware design, software design, algorithm optimization and analysis. The system used in hospital laminar flow operation room, stable value of conductivity, maintaining the error within specified range, reached the standard of operation room the use of water.
