西门子SMART系列PLC在血液透析水处理设备中的应用设计
西门子SMART系列PLC在血液透析水处理设备中的应用设计摘要：在本次对水处理设备的升级改造中，使用了SMART系列PLC的SR40型号CPU作为控制器，SAMRT700IE人机界面作为监视操作器，EMAM06(4AI/2AQ)对电导率、压力、温度等模拟量信号进行处理。
通过次改造，充分发挥了SR40型号CPU的系统功能，来实现对设备的控制和监控，也使我对小型机的功能有了新的认识。
一、项目简介随着我国经济的快速发展，综合国力的显著提高，科学技术在各学术领域内交流与合作的广泛开展;作为血液透析水处理设备净化领域内重要组成部分之一——水处理，得到了越来越多的关注。
它的进步与发展，将直接影响医用检验分析纯水机到患者的生存质量，对改善和延续患者的生命有着深远的意义。
衡量透析用水处理产品优劣的标准是其能否为血液透析提供优质的纯化水。
其本身作为一种医疗设备，功能的完备性、性能的稳定性、操作的方便性也是一项十分重要的指标。
2015年3月国家药监局即将实施新的透析用水标准（YY0572-2015），新标准对水处理设备提出了更高的要求，为了响应国家要求同时适应市场发展，公司决定对整套系统升级改造。
考虑到医疗设备对系统稳定性的要求，决定控制系统改用西门子控制系统。
二、工艺原理市政自来水—原水箱—原水泵—砂滤器—炭滤器—软化器——精密过滤器---反渗透主机---纯水箱——纯水泵——UV杀菌器——精密过滤器---―纯水1、原水箱作用：克服管网供水的不稳定性，保证整个系统的供水稳定连续；同时也给各设备长期性能可靠提供了保障。
2、原水泵作用：给预处理各设备提供必需的工作压力。
3、机械过滤器（石英砂过滤器）作用：原水首先经过机械过滤器，在过滤器中放置12-24目的精致石英砂，使原水中的絮凝体、铁锈等悬浮杂质在此过程中被截留。
由于机械过滤器在工作中截留了大量的悬浮杂质，。

早产儿治疗用氧和视网膜病变防治指南
随着我国围产医学和新生儿学突飞猛进的发展，新生儿重症监护病房（neonatal intensive care unit，NICU）的普遍建立，早产儿、低体重儿的存活率明显提高，曾在发达国家早期就已出现的早产儿视网膜病变（retinopathy of prematurity，ROP）在我国的发病有上升趋势。
ROP严重时可导致失明，是目前儿童盲的首位原因，对家庭和社会造成沉重负担。
ROP的发生原因是多方面的，与早产、视网膜血管发育不成熟有关，用氧是抢救的重要措施，又是致病的常见危险因素。
出生孕周和体重愈小，发生率愈高。
2004年卫生部颁布了中华医学会制定的《早产儿治疗用氧和视网膜病变防治指南》，积极推动了我国早产儿救治和ROP防治的工作进程，但目前ROP的防治任务仍十分严峻。
ROP最早出现在矫正胎龄（出生孕周+ 出生后周数）32周，早期筛查和正确治疗可以阻止病变的发展。
为进一步解决这一严重影响早产儿生存质量的问题，做好ROP的防治工作，减少ROP致盲率，中华医学会眼科学分会眼底病学组重新修订中国早产儿视网膜病变筛查指南，供临床应用。
一、疾病定义、分区和分期、专业术语1．定义：ROP是发生在早产儿和低体重儿的眼部视网膜血管增生性疾病。
2．病变分区：按发生部位分为3个区（图1）：Ⅰ区是以视乳头中央为巾心，视乳头中央到黄斑中心凹距离的2倍为半径画圆；Ⅱ区以视乳头巾央为中心，视乳头巾央到鼻侧锯齿缘为半径画圆，除去Ⅰ区之后的环状区域；Ⅱ区以外剩余的部位为Ⅲ区。
早期病变越靠近后极部（Ⅰ区），进展的风险性越大。
3．病变分期：病变按严重程度分为5期（图2～7）：（1）1期：约发生在矫正胎龄34周，在眼底视网膜颞侧周边有血管区与无血管区之间出现分界线；图2 早产儿视网膜病变1期眼底像（2）2期：平均发生于矫正胎龄35周（32-40周），眼底分界线隆起呈嵴样改变；图3 早产儿视网膜病变2期眼底像，可见分界线隆起呈嵴状（3）3期：平均发生于矫正胎龄36周（32-43周），眼底分界线的嵴样病变上出现视网膜血管扩张增殖，伴随纤维组织增殖；阈值前病变平均发生于矫正胎龄36周，阈值病变平均发生于矫正胎龄37周；图4 早产儿视网膜病变3期眼底像，可见嵴上出现新生血管（4）4期：由于纤维血管增殖发生牵拉性视网膜脱离，先起于周边，逐渐向后极部发展；此期根据黄斑有无脱离又分为A和B，4A期无黄斑脱离，4B期黄斑脱离；图5 早产儿视网膜病变4A期眼底像，可见周边牵拉性视网膜脱离图6 早产儿视网膜病变4B期眼底像，为图5患儿3周后，可见周边牵引性视网膜脱离累及黄斑（5）5期：视网膜发生全脱离（大约在出生后10周）。

General corrosion resistance of Sandvik 3R64 and ASTM 316 in boiling formic acid.Formic acid, wt-%Corrosion rate, mm/year Sandvik 3R64ASTM 31650.120.18100.200.3250.350.6500.450.680 1.0 1.5900.8 1.81000.40.6Intergranular corrosionOwing to its low carbon content Sandvik 3R64 possesses a low risk for intergranular corrosion after e.g. welding operations.Pitting and crevice corrosionThe pitting corrosion resistance of stainless steels is primarily determined by the contents chromium,molybdenum and nitrogen. The Pitting Resistance Equivalent can be used for ranking different stainless steels with regard to their pitting resistance. The PRE number is defined as:PRE = % Cr + 3.3 x % Mo + 16 x % NTable 2. PRE values for Sandvik 3R64 and some other alloys. Typical values unless otherwise statedOrganic acids at high concentrations and moderate temperatures–Inorganic acids, e.g. phosphoric and sulphuric acids at moderate concentrations and temperatures. The steel can also be used in sulphuric acid of concentrations above 90% at low temperature –Salt solutions, e.g. sulphates, sulphides and sulphites caustic environments–D a t a s h e e t u p d a t e d 1/19/2017 12:21:59 P M (s u p e r s e d e s a l l p r e v i o u s e d i t i o n s )4Alloy 3R64ASTM 316L Alloy 825904L SAF 2205PRE29243134>351) 2.1 % MoThus Sandvik 3R64 is resistant against pitting corrosion at higher temperatures and/or higher chloride concentrations than is the case for ASTM 316L.Figure 1. Crevice corrosion resistance of Sandvik 3R64 and 3R60.The same ranking of alloys can be applied for the crevice corrosion resistance. However, crevice corrosion is to be expected at significantly lower temperatures, than is the case for pitting corrosion. Figure 1 demonstrates the better crevice corrosion resistance of Sandvik 3R64 vs. 3R60 (ASTM 316L with 2.6% Mo, EN 1.4435) after 2months exposure in chloride solutions.Stress corrosion crackingAustenitic steels are susceptible to stress corrosion cracking. This may occur at temperatures above about 60°C (140°F) if the steel is subjected to tensile stresses and at the same time comes into contact with certain solutions, particularly those containing chlorides. Such service conditions should therefore be avoided.Conditions when plants are shut down must also be considered, as the condensates which are then formed can develop a chloride content that leads to both stress corrosion cracking and pitting.In applications demanding high resistance to stress corrosion cracking, austenitic-ferritic steels, such as Sandvik SAF 2304 or Sandvik SAF 2205 are recommended. See data sheets S-1871-ENG or S-1874-ENG.1)HEAT TREATMENTThe tubes are delivered in heat treated condition. If additional heat treatment is needed after further processing the following is recommended.Stress relieving850–950°C (1560–1740°F), 10-15 min, cooling in air.Solution annealing1000–1100°C (1830–2010°F), 10-30 min, cooling in air or water.WELDINGThe weldability of Sandvik 3R64 is good. Suitable welding methods are manual metal-arc welding with covered electrodes and gas-shielded arc welding with the TIG and MIG methods as first choice. Preheating and post-weldD a t a s h e e t u p d a t e d 1/19/2017 12:21:59 P M (s u p e r s e d e s a l l p r e v i o u s e d i t i o n s )5/contact-us Disclaimer: Recommendations are for guidance only, and the suitability of a material for a specific application can be confirmed only when we know the actual service conditions. Continuous development may necessitate changes in technical data without notice. This datasheet is only valid for Sandvik materials.heat treatment are not normally necessary.Since the material has low thermal conductivity and high thermal expansion, welding must be carried out with a low heat input and with welding plans well thought out in advance so that the deformation of the welded joint can be kept under control. If, despite these precautions, it is foreseen that the residual stresses might impair the function of the weldment, we recommend that the entire structure be stress relieved. See under "Heat treatment".As filler metals for gas-shielded arc welding we recommend wire electrodes and rods Sandvik 19.13.4.L. In shielded metal-arc welding (SMAW) covered electrodes Sandvik 19.13.4.LR are recommended.APPLICATIONSSandvik 3R64 can be used for a wide range of industrial applications where steels of type ASTM 304 and 304L or even ASTM 316L have insufficient corrosion resistance. Typical examples are heat exchangers, condensers,pipelines, cooling and heating coils in the chemical, petrochemical, pulp and paper and food industries.D a t a s h e e t u p d a t e d 1/19/2017 12:21:59 P M (s u p e r s e d e s a l l p r e v i o u s e d i t i o n s )。

Other problematic areas included shoulder, wrist and hand.78%Unrivalled Mantis advantage...Businesses choose Vision Engineering’s ergonomic stereo microscopes because operators are more comfortable during inspection, so more efficient, more accurate and more productive.Give your stereo microscope a health check!Ergonomic working positionAn ergonomic body position makes the Mantis more comfortable, less fatiguing and, more importantly, much easier to use. Additionally, optimal operator ergonomics minimises the risk of repetitive strain-related injuries. A happy worker is a productive worker.Freedom of head movementAn additional benefit of Vision Engineering’s patented eyepiece-less design is that users do not need to align their eyes with eyepieces. This freedom of movement reduces associated neck and back strain associated with the fixed body position of conventional microscope eyepieces.A natural view of the subjectWith conventional microscope eyepieces, operators must position their eyes very close to the eyepieces, blocking out ambient light. The intense light exiting the eyepieces causes the pupils to contract. Constant contraction and expansion of the pupils is the main cause of eye fatigue with microscopes.With the patented eyepieces of Mantis, users sit back from the viewer, allowing ambient light into the eyes. Additionally, the light exiting the ‘viewing lens’ is spread overa larger area, proving a more natural view of the subject.Easy hand-eye co-ordinationEasy hand-eye co-ordination is possible with the Mantis – critical for re-work, repair, dissection and other manipulation tasks. Sitting back from the viewer provides userswith much better peripheral vision, so they can co-ordinate hands in a natural manner.Ability to wear glassesWith Mantis, operators do not need to remove their glasses (or safety glasses) to use the microscope./ergonomicsDisclaimer - Vision Engineering Ltd. has a policy of continuous development and reserves the right to change or update, without notice, the design, materials or specification of any products, the information contained within this brochure/datasheet and to discontinue production or distribution of any of the products described.EO&E: Errors and omissions accepted.Mantis_LIT5429EN_10.1| Copyright ©2022 Vision Engineering Ltd. | All rights reserved.To see our focused quality , please contact your Vision Engineering branch, local authorised distributor, or visit our website: Vision Engineering Ltd.(UK Manufacturing & Commercial)The Freeman Building, Galileo Drive, Send, Surrey, GU23 7ER, UK T +44 (0) 1483 248300E ************************.uk Vision Engineering Ltd.
