手持配药器本科毕业论文

哈尔滨工业大学（威海）学士学位论文-I-摘要在医院护理的日常工作当中，配药是一项很重要的工作，根据不同病人用药的要求，需要将不同的药品分别配制于输液瓶中，再输入到病人体内。在医院，尤其是一些大医院，护理人员每天需要配制大量的药液供医院病人使用，他们的工作量和工作强度都很大，手上常常包扎很厚的绷带。一款自动化的配药器械完全符合医院护理工作者的期望，配药器械的应用及普及可以减轻护理人员的劳动强度，提高配药效率，同时，减少了护理人员接触配药所用注射器的机会，可以大大减少院内交叉感染现象的发生，也能对一线护理人员起到很好的保护作用。医用手持配药器是一款医院护理人员在配药时使用的自动化的配药器械,本文对医用手持配药器进行了综合设计，主要包括外壳设计、传动机构设计、执行机构设计、控制系统电路板设计、控制系统程序设计。该医用手持配药器由220V电源供电，经电源适配器向整个控制系统提供12V电源，并驱动有刷直流电机，电机输出动力经齿轮传动带动转筒转动，进而转换成执行器的直线移动，带动注射器推拉杆的直线运动，实现配药时注射器的抽取药液和注射药液的过程。医院护理人员只需在配药器侧面进行必要的按键操作，即可通过载入控制器程序的运行，完成电机的转动控制，电机码盘实时反馈电机运转数据至控制器，保证电机转动精度，进而提高配药器抽取或注射药量的精度。开发此款手持配药器不仅具有重要的现实意义：提高工作效率，降低工作强度，降低操作发生事故的风险，对一线配药护士的保护作用；还能带来新的经济增长点，即促进其配套专用注射器的使用和销售。关键词：医用手持配药器；注射器；配药；医疗器械哈尔滨工业大学（威海）学士学位论文-II-AbstractInthedailyworkofhospitalcare,dispensingisaveryimportantjob.Dependingontherequirementsofthepatientmedication,differentdrugsneedtobepreparedintheinfusionbottle,respectively,then,enterintothepatient.Inhospital,especially,somelargehospitals,paramedicsneedalotofliquidpreparationforhospitalpatients,theirworkloadandworkintensityarelarge.Theirhandsareoftenverythickbandagewrapped.Anautomateddispensingequipmentfullycomplywiththeexpectationsofhospitalcareworkers.Theapplicationandpopularizationofdispensingequipmentcanreducethelaborintensityofnursing,improvedispensingefficiency.Atthesametime,nursescanreducethechanceofdispensingsyringesused,greatlyreducetheoccurrenceofthephenomenonofcrossinfection.Also,nursescanplayaverygoodfirst-lineprotection.Dispensingdeviceofhandheldmedicalisadevicethatnursesintheuseofautomateddispensingequipmentdispense.Thismedicalhand-helddispensingdevicewereintegrateddesign,includehousingdesign,drivingmechanism,actuatordesign,controlboarddesign,controlsystemprogramming.Medicalhand-helddispensingdeviceisfromthe220Vpowersupply.Thepoweradaptertopowertheentirecontrolsystem12V.brushingDCMotorDriver.Electricpoweroutputdrivestherotorrotationviathegears.Themotionofactuatorconvertedintolinearmotion.Toachievetheextractionliquiddispensingsyringeandinjectionprocessofliquid.Hospitalnursesdispensingjustneedkeyoperationnecessary.Runningthroughtheloadcontrolprogram,Motorencoderdatainreal-timefeedbacktothecontroller,motoroperation.Itcanensureaccuracyofthemotorrotation,extractionorinjectiondevicetoimprovedispensingaccuracyofthedose.Developmentofthissectionnotonlyhasthehand-helddispensingpracticalsignificance:improveefficiency,reducetheintensityofwork,reduceoperatingriskofaccidents,protectionoffirst-linerolenursesdispensing.Itcanbringneweconomicgrowthpoint:supportingdedicatedtopromoteitsuseandsaleofsyringes.哈尔滨工业大学（威海）学士学位论文-III-Keywords:Medicalhand-helddispensingdevice;Syringe;Dispensing;MedicalDevices哈尔滨工业大学（威海）学士学位论文-IV-目录摘要...............................................................................................................................IAbstract........................................................................................................................II第一章绪论................................................................................................................11.1课题背景及研究意义........................................................................................11.2配药器的发展及市场........................................................................................21.2.1配药器的发展现状.....................................................................................21.2.2配药器的市场分析.....................................................................................31.3医用手持配药器的特点....................................................................................3第二章主要研究内容及整体方案............................................................................52.1医用手持配药器的研制目标...........................................................................52.2医用手持配药器的整体方案............................................................................62.2.1医用手持配药器需求分析........................................................................62.2.2医用手持配药器整体设计方案.................................................................7第三章理论基础........................................................................................................9第三章医用手持配药器各部分设计......................................................................113.1系统机构设计.................................................................................................113.1.1传动机构设计..........................................................................................113.1.2执行结构设计...........................................................................................143.1.3外观设计...................................................................................................143.2系统硬件设计..................................................................................................153.2.1控制系统设计需求分析...........................................................................153.2.2控制系统总体方案设计...........................................................................153.2.3控制系统的硬件原理图设计...................................................................163.2.4印制电路板的设计
