This allows you to further process or store the samples without having to wait for the run to finish. You can also define that the sample carriers be left in the instrument and manually unloaded when the run is finished. Roche tiiagnostics 44 System Manual Version 1. During operation, the pipetting arm moves left-and-right x direction , picks up the required number of disposable pipetting tips, aspirates, dispenses, and mixes the liquids, and then ejects the used tips into the tip solid waste bag.
Each air-displacement pipetting channel can move forward-and-back y-direction and up-and-down z-direction during the pipetting operation. A disposable pipetting tip is picked up by each pipetting channel at the beginning of a pipetting cycle. The pipetting tip is ejected into the tip solid waste bag at the completion of pipetting for that cycle. A Pipetting channel B Pipette stop disc Figure C Pipetting arm Pipetting arm of instrument Each pipetting channel contains a pipette stop disc which aligns the disposable pipetting tip when it is picked up by the pipetting channel at the beginning of a pipetting cycle.
Aspiration and dispensing is achieved by air displacement. The pipette stop disc does not contact the liquid that is being aspirated into and dispensed from the disposable pipetting tip. The pipette stop discs must be cleaned on a weekly basis.
For additional details, see Weekly niaintenance p. A iSWAP Figure ISWAP Teaciting needies The instrument uses eight teaching needies to automatically check and adjust if necessary z-positioning and over- and under-pressure of each pipetting channel at the appropriate time. The teaching needies are stored near the waste station, next to the tip waste.
The teaching needies are cleaned during the preventive maintenance visit. The following safety messages in particular are relevant: Warning messages: Infection by biohazardous waste p. The instrument can be installed on either a bench top or on a trolley that accommodates a larger solid waste bag. This solid waste bag has a capacity for tips of at most one full run. Exchange the small solid waste bag each time before starting a new run to avoid overfilling of the tip waste.
For details about replacing the small solid waste bag, see Daily niaintenance p. The large solid waste bag holds tips of at most three full runs. The level of the liquid waste is monitored by the system and a warning is issued when it is not possible to do a full run. In this case, it is not possible to start the run.

Run results will be invalid. Processing of the sample was aborted. Figure 2 shows this scenario. No changes can be made at this level and because the system is implemented over a network communication, it just acts as an intermediate level inside the application layer, transmitting the data to the upper ASTM layer. The short description of the ASTM lower layer is here for information. Messages equal to or less than characters are transmitted as one final frame. Messages greater than characters are split into frames that have character lengths that fall within the character limit.
Results timeout: Timeout for messages sent by the cobas system: From the ENQ, the transmission including multiple frames should not exceed seconds. The test order segment is holding all information related to a sample. Note: Missing orders. For samples that do not have a corresponding test request in the Host system, the whole O segment record must be skipped. Example: If the sample numbers and do not have a test for cobas , the lines marked in bold in the ASTM response from the Host would not exist.
The Host system may have to further parse the result block if a further separation of individual subcomponents is required. See the tables 11 for details and possible combinations inside result blocks. HL7 messages are embedded in block delimited by special non printable characters.
See table below. The observation request segment is holding all information related to a sample. The network address of the instrument is normally determined by the installation of a cobas IT firewall.
To change the network address, you must log into the operating system as local Administrator. Please ask the Roche service representative. Instrument Setup By default the HIF modules are not installed, for the instrument setup, please refer to the Network Configuration Guide cobas system. This installation has to be performed by qualified Roche service personnel. Once the software for host interface has been installed, some parameters can be changed to match the requirements of the LIS system.
The default protocol after installation is HL7. This software can be installed on Windows computers and are intended to be used only by Roche trained personnel. When used as an instrument simulator, the goal is to provide only a quick test tool for testing the transmission formats. Please keep in mind that the simulator does not react like a real instruments in all situations. The simulator is intended to be used for several Roche instruments, periodically new ones will be added.
From version 2. They will be installed by default under Host Interface tools. The user needs administrator rights to be able to install the host tools package properly. After the basic installation of the "Host tools" package, some patches may be required depending on the simulator you intend to use. Please ask the Roche service representative for further information.
Network card HL7 Simulator Roche has developed a specific host simulator to make simple testing of the HL7 protocol, for the cobas Instrument. To start the simulator, simply select from the stat menu as shown.
The simulator must be set up as a server. That is, it will listen on a defined port. Port is often used as a default. The server IP address is the address of the network card and cannot be changed for a server.
It comes from the network settings of the computer hosting the simulator. This is the same as the LIS address that must be set on the cobas when installing or setting up the Host. This has the effect of enabling the correct responses from the simulator to the selected type of instrument. Once every minute, the cobas communication server will attempt a connection on the defined IP address and port.
If the simulator is reached, the connection indicator will turn from yellow to green as shown. Additionally, the IP address of the connected system will appear in the lower part of the blue box Remote. At this point the simulator can be used and will display the HL7 records received and sent.
In some circumstances, the simulator may erroneously indicate an active connection. This can be the case if there are elements in the network that where temporarily disconnected. If the LIS seems unresponsive although the connection is displayed as active, make the connection check.
