This part is called MEDIBUS."Fast" data:Intended for the transmission of e. g. realtimecurves. This part of MEDIBUS is called the "Real-time-Extension".This manual contains a general description of theprotocol including formats of commands andresponses.For device dependent descriptions of supportedcommands and data sets, port hardware and con-figurations for Dräger devices please refer to theindividual device-specific MEDIBUS documenta-tion.Dräger RS232MEDIBUS3MEDIBUS IntroductionMEDIBUS IntroductionThe MEDIBUS protocol distinguishes two basictypes of messages:–commands–responses.A command is transmitted by one device to requestdata from the other device or to control its function.A response is transmitted by one device uponreceipt of a command from the other device.Responses may contain embedded commands.Initializing Communication(refer to MEDIBUS-life-cyle-diagram, see page40)–To initialize communication or to restart commu-nication after a time-out, a device must send the"Initialize Communications Command" ICC.Refer to section "Control commands" for the for-mat of commands.– A device considers communication initializedafter having received either a response to atransmitted ICC or an ICC from the otherdevice. Refer to section "Responding to com-mands" for the format of responses.–Commands embedded in a response to an ICCare disregarded.4Dräger RS232MEDIBUSMEDIBUS Introduction Terminating Communication–To stop the communication the "STOP" com-mand has to be sent.–The command echo has to be checked to makesure the "Stop Communication" command hasbeen received correctly. Further commandsfrom the linked device may be ignored until thecommunication has been reinitialized.Time-Out–Any pause in the data flow exceeding 3 sec-onds leads to a time-out, terminating the com-munication link. To resume communication aftera time-out, the device must re-initialize commu-nication by transmitting an ICC command (seesection "Initializing communication", page4).Whenever a device receives an ICC command,it must send a response to it (see section"Responses", page12).–After receiving a command the device has tosend a complete response within 10 seconds.–If there is no need for sending commands orresponses the "NOP"–command has to be sentin 2-second-intervals to keep the communica-tion alive.Allowable Characters–Printable ASCII characters.–Control characters defined in this Instructionsfor Use.Dräger RS232MEDIBUS5MEDIBUS Introduction6Dräger RS 232MEDIBUSSoftware HandshakingSome control characters can be sent at any time to control the flow of data. They do not require responses.Suspending data transmission–If a receiving device wants the transmitting device to suspend transmission, the ASCII "DC1" character (11H) must be sent.–Upon receipt of this character, the sending device will suspend any transmission immedi-ately until it receives the ASCII "DC3" character.Resuming data transmission–To request the transmitting device to resume data transmission, the ASCII "DC3" character (13H) must be sent within 3 seconds. Else com-munication will be reinizialized with an ICCcom-mand.Aborting data transmission–To request the other device to abort sending a response or a command, the ASCII "CAN" character (18H) must be sent.–Upon receipt of this character, any transmission in progress will be immediately aborted. Com-munication may be restarted by repetition of the last sent command immediately.Dräger RS 232MEDIBUS7MEDIBUS CommandsMEDIBUS CommandsStructure of Commands–A command is a string of ASCII characters transmitted by one device to request data from the other device or to control its function.–A command may be embedded in the response to another command, but a new command must not be transmitted until the response to the pre-vious command has been received.–If, however, the response to a command has not been received in full within 10 seconds since the transmission of the last command byte, the command may be repeated or a new command may be transmitted.Commands have one of the following formats:ESC ASCII "escape" character (1BH)Command-Code Single byte code specifying the command.ARGUMENTThe argument string is of variable length n, but n must not exceed 251(0FBH) bytes. The string consists of printable ASCII characters, either text or ASCII HEX numbers. The for-mat of the different arguments are specified in the following sections.CHECKSUM Least significant 8-bit sum of all preceding bytes beginning with "ESC" in ASCII HEX format (see section "ASCII HEX Format", page 45). CRASCII "carriage return" character (0DH)010NOTETo avoid communication breakdown, commands with arguments must not be sent to devices with a MEDIBUS version less than 3.00.MEDIBUS CommandsCommand CodesControl CommandsControl commands are used to initialize, controland stop communication.Command CodeNo Operation (NOP)30HInitialize Communication (ICC)51HStop Communication (STOP)55HData Request CommandsData request commands are used to request data.Command CodeRequest current Alarms (Codepage 3)23HRequest current measured Data (Codepage 1) 24HRequest current low Alarm Limits (Codepage 1) 25HRequest current high Alarm Limits (Codepage 1) 26HRequest current Alarms (Codepage 1) 27HRequest current Date and Time 28HRequest current Device Setting 29HRequest current Text Messages 2AHRequest current measured Data (Codepage 2) 2BHRequest current low Alarm Limits (Codepage 2) 2CHRequest current high Alarm Limits (Codepage 2) 2DHRequest current Alarms (Codepage 2) 2EHRequest Device Identification 52HRequest Trend Data Status6CHRequest Trend Data6DH8Dräger RS232MEDIBUSMEDIBUS CommandsMiscellaneous CommandsCommand CodeTime changed49HConfigure Data Response Command4AHTime Changed CommandThe "Time changed" command is sent if duringruntime the time or date of the device has beenchanged. The receiving device can now ask for cur-rent date and time. Because of the "Time changed"command there is no need for sending periodicallythe "Request Current Date and Time" command.Dräger RS232MEDIBUS9MEDIBUS Commands10Dräger RS 232MEDIBUSConfigure Data Response CommandThe "Configure Data Response" command is used to limit the number of data responded by a data source on a data request command. On receipt of any of these data request commands the receiver has to send all actual valid data. In cases where only a few of the possible data are used, the requesting device may configure the responding device to send only these used data by sending a "Configure Data Response" command. The codes of useful data are given in the argument as follows:DATA TYPE:One byte identifying the data type to configure.This may be:DATA CODE:Two byte ASCII HEX data code. See appendices for code numbers.The configuration stays valid until receipt of a new "Configure Data Response" command. After re-ini-tializiation of communication (ICC) and if the "Con-figure Data Response" is send without data codes, the configuration is set to its default state, where internal programmed configuration is used. An example is given in Appendix.01124H for current Data, low Alarm Limits and high Alarm Limits (codepage 1)27H for current Alarms (codepage 1)29H for current Device Settings 2AH for current Textmessages2BH for current Data, low Alarm Limits and high Alarm Limits (codepage 2)2EHfor current Alarms (codepage 2)MEDIBUS Commands Request Trend Data CommandThe “Request Trend Data” command (6DH) is usedto request a sequence of samples of one trendparameter.The command argument has the following format:CODE PAGE DATA CODE COUNT BEGIN0+2+4+6+14CODE PAGE:Two byte ASCII HEX number identifying the code page of the trend parameter: 24H for data code page 12BH for data code page 2DATA CODE:Two byte ASCII HEX number containing the data code of the trend parameter. A param-eter's data code is the same as used for the "Request current measured data" response. COUNT:Two byte ASCII HEX number defining the maximal number of trend samples allowed in the response.BEGIN:Eight byte ASCII HEX number specifying the time stamp of the eldest requested trend sample. (Note: BEGIN is undefined if COUNT is 0.)The time stamp is packed in accordance to the Microsoft Windows™ 32-bit date andtime format:NOTEBEGIN ist undefined if COUNT is 0.YYYYYYYMMMMDDDDDhhhhhmmmmmmsssssMSB LSBwithYYYYYYY year relative to 1980 (range 0 - 119)MMMM month (range 1 - 12)DDDDD day (range 1 - 31)hhhhh hour (range 0 - 23)mmmmmm minute (range 0 - 59)sssss second (range 0 - 29 in 2-second intervals)NOTEPrior to the "Trend Data Request" the device shouldrequest the trend data status in order to know theavailability of trend data (refer to chapter "Trend DataStatus Response" for the respective response).Dräger RS232MEDIBUS11MEDIBUS Responses12Dräger RS 232MEDIBUSMEDIBUS ResponsesStructure of ResponsesUpon receipt of a command, a device must respond to it within 10 seconds.

In opposite to thestandard protocol the MEDIBUS device extensionfor infusion pumps is meant to support severalpumps on one communication port, all pumpssourcing identical data items, e.g. the same mea-sured data, alarms, settings etc.MEDIBUS Device Extension Protocol ConceptThe basic concept of the MEDIBUS device exten-sion is stacking the MEDIBUS Device Extensioncommand 59H with sub-command codes andaddressing a specific pump by a channel number.Stacking of command codes means that a deviceextension telegram always uses the leading com-mand code 59H to indicate that the telegram is aMEDIBUS Device Extension command orresponse for infusion pumps. The leading com-mand is followed by a sub-command code, e.g.specifying the actual data update request. If appli-cable the sub-command is followed by a channelnumber, defining to which device the telegram isrelated.22Dräger RS232MEDIBUSMEDIBUS Device Extension for Infusion Pumps Infusion Pump CommandsLeading Command Code Device Extension Command for Infusion Pumps59HSub-Commands Code Request current measured data24H Request current low alarm limits25H Request current high alarm limits26H Request current alarms27H Request current device settings29H Request current text messages2AH Request infusion pump configuration41H Infusion pump configuration changed42HDräger RS232MEDIBUS23MEDIBUS Device Extension for Infusion PumpsInfusion Pump Communication Life CycleThe following diagram shows a typical communica-tion life cycle for a device being connected to aninfusion pump device.324Dräger RS232MEDIBUSDräger RS 232MEDIBUS 25MEDIBUS Device Extension for Infusion PumpsRequest Infusion Pump ConfigurationAfter communication has initialized the requesting device first has to ask the pump device for available pumps using the Request Infusion Pump Configu-ration sub-command (41H).The pump device will respond with a list of identifier for available pump channels.Later these pump channel identifier have to be used by the requesting device to request data from a specific pump.Request Infusion Pump Configuration Command:Infusion Pump Configuration Response:ESC Lead-CommandSub-Command 41H Checksum D9H CR 1BH59H34H31H44H39H0DHESCLead-Com-mand Sub-Command 41H Pump channel01H ….Pump channelxyH ChecksumCR01H 59H34H31H30H31H….xxHyyHCS1CS20DHSub-Command: 2 bytes ASCII-Hex field.Pump channel:2 bytes ASCII-Hex field specifying the identifier of available infusion pump channels within the range of 0 to 255 (00H to FFH).MEDIBUS Device Extension for Infusion PumpsInfusion Pump Configuration Changed CommandIf an infusion pump has been added to or removedfrom the pump device and the pump device hasbeen asked for its configuration before, the pumpdevice will issue an Infusion Pump ConfigurationChanged sub-command (42H).After receiving the Infusion Pump ConfigurationChanged sub-command the requesting device hasto restart the infusion pump communication againby sending the Request Infusion Pump Configura-tion sub-command.Infusion Pump Configuration ChangedCommand:ESC Lead-Command Sub-Command 42H Checksum DAH CR 1BH59H34H32H44H41H0DHInfusion Pump Configuration ChangedResponse:SOH Lead-Command Sub-Command 42H Checksum C0H CR 01H59H34H32H43H30H0DHSub-Command: 2 bytes ASCII-Hex field.26Dräger RS232MEDIBUS。

一旦麻醉机出现异常，麻醉药物的浓度就可能出现异常，对患者的手术治疗以及生命健康就会产生极大的威胁[3]。
因此，麻醉机的功能正常、性能稳定就显得尤为重要。
由此，也就要求维修人员要熟练掌握麻醉机的构造及工作原理，掌握一定的维修技术和维护保养措施，能够正确地分析故障原因、及时排除解决故障。
这样可以全面提升设备的使用质量，降低使用成本，为医院的发展创造更多的经济与社会效益[4]。
本文通过麻醉机原理简介及一例维修案例的分享，总结探讨维修经验、方法。
1 结构原理目前麻醉机品牌很多，但按其原理结构基本可分为：气体供应输送系统、麻醉气体挥发罐、呼吸回路、麻醉呼吸、安全监测系统及残气清除系统[5]。
