CHAPTER 1: INTRODUCTION The Vitalograph 2120 is a hand-held spirometer designed for lung function testing in a variety of environments, for example, hospital wards, occupational health centres, and clinical trials. The Vitalograph 2120 is particularly designed for testing in-situ, taking the spirometer to the subject, rather than the subject to the device. The Vitalograph 2120 Service Manual should be used in conjunction with the Vitalograph 2120 User Manual.

Principle Of Operation Instantaneous expired and inspired respiratory air is detected with a Fleisch pneumotachograph type of flowhead. Inside the flowhead is a resistance: a series of small parallel tubes which maintain laminar flow in the air passing through it. This creates a differential pressure proportional to air flow rate which is monitored by a pressure transducer which is part of the main PCB. The output from the pressure sensor is passed through a 12 bit A/D converter. The digital signals from the A/D is monitored and analysed by the software controlled by a 80C652 microprocessor. Results are calculated and displayed on a 4 x 20 character LCD.

CHAPTER 2: SYSTEM CONFIGURATION Always ensure that the Power Supply is connected to the cradle in order to recharge the 2120 battery pack. The Vitalograph 2120 is not required to be switched on for charging to take place. The unit is switched on with the blue slide switch on the side of the unit.

Fig. 1 System configuration of Vitalograph 2120.

For a description on how the 2120 software interface is operated, the Vitalograph 2120 User Manual (081006) should be consulted. For software of version 2.00 and greater, use the User Manual 07022. The introduction of the cradle to the 2120 brought about the new user manual 07145. If printing to a serial Printer For serial printing a 9 - 25 ‘D’ adapter (2100011) is required to interface between the Vitalograph 2120 cable and the serial port of the printer. 1. 2.

Connect the 9 pin end of the Adapter to the end of the cable attached to the Vitalograph 2120. Connect the 25 pin end of the RS232 Adapter to the serial printer.

Serial data format: Baud rate 9600bps 1 Start bit 1 Stop bit 8 Data bits No parity check Printers with serial ports can be set up for the above information using DIL switch settings. The following example is based on the HP Deskjet 500. Bank A 1. down 2. down 3. down 4. down 5. down

CHAPTER 3: ACCURACY CHECK/CALIBRATION ADJUSTMENT The calibration routine allows the user to check, and adjust if necessary, the calibration of the instrument. The revised calibration is retained until altered again, even when the machine is switched off. To perform the accuracy check/calibration a precision syringe is required (as in Fig. 2). Attach the Vitalograph 2120 to the precision syringe as illustrated in the following diagram i.e. with the on/off switch towards the table. A 1 L, 2L or 3L syringe may be used. Before checking calibration it is essential that the flowhead and syringe are at the same ambient room temperature. Expiration through the flowhead raises its temperature. If the flowhead has recently been used for testing then the temperature must be lowered to ambient by pumping room air through it prior to calibration using the syringe. Note: An accuracy check should be performed after Cleaning / Disinfecting the Flowhead Fleisch Element Assembly or after 2120 Disassembly / Re-assembly. If the 2120 has just been programmed with new software, a calibration will need to be done. Always update the calibration in this case. This will ensure that the calibration log on Spirotrac IV will not contain a date of 00/00/00 for a Calibration Update date.

Fig. 2 Calibrating the Vitalograph 2120

Recommended Accuracy Check Procedure 1.

Connect the Vitalograph 2120 to a syringe ( we recommend the Vitalograph l Litre syringe - Cat No 20408

2.

Prior to checking accuracy, have your calibrating syringe ready (we recommend the Vitalograph 1 litre syringe Cat. No. 20408).

3.

From the main menu, select Calib.

4.

Using the T and S buttons, enter the ambient temperature (you will only have to do this the first time the unit is used for checking accuracy after it is switched on).

5.

Using the T and S buttons, set the calibrating syringe volume. It is very important to set this up correctly, otherwise, the accuracy check will not function properly.

6.

Ensure the syringe piston is fully withdrawn. At this point, connect the unit to the syringe and leave it in a stable position - do not move the unit during this procedure.

7.

With an even stroke, pump the contents of the syringe into the unit. The stroke must be at least one second in duration.

8.

Wait for a double beep, withdraw the syringe piston fully and repeat step 6 until five beeps occur (it is very important to wait for the double beep before withdrawing the piston each time).

9.

The accuracy check is now complete. Press ↵ to continue.

10.

The accuracy is within tolerance when the volume difference with the previously stored calibration value is less than 3%. There is no need to update calibration here. (if, for some reason, an update is still required then press the DEL button at this stage) If the volume difference to the stored calibration value is greater than 3%, then an update is recommended.

11.

An accuracy check report can be printed when prompted to do so. Ensure your printer is set up correctly (refer to Connecting the Vitalograph 2120 To A Printer in part 1 of the Quick Start Guide - 081007 or 07023), and press ↵, otherwise press ESC.

Note: if you check accuracy during a test session and attempt to update the calibration, you will be informed that the current test session will be completed. If you press ↵, the calibration will be updated and the best test to date will be saved to the database. If you press ESC, the calibration will not be updated and testing can resume.

CHAPTER 6: REPLACING PARTS Main PCB NB: After the PCB has been replaced, the hexfiles must be codeloaded. When the loading process is completed the 2120 must also be initialised before re-use. See software section later on in this chapter. Dismantle the Vitalograph 2120 as described in Section E. The Main PCB is situated in the case upper as illustrated in Fig. 5.

Fig. 5 Case Upper

Remove the four holding screws and lift the PCB assembly clear of the unit. Care should be taken here as the LCD is attached to the Main PCB via an inter PCB 14 way connector. The tail of the membrane keypad is also connected to the Main PCB on the underside. Unplug the tail of the membrane keypad. Remove the switch cap from the slide switch on the Main PCB. Fit the new PCB using the reverse of this procedure. Note 1: Always load hex files when the main PCB is replaced in the 2120. Note 2: If the unit will be programmed with version 2.00 of software or greater, the PCB S/X 74057 will have to be used. The differing factor between this and the PCB S/X for version 1.xx of software, is the BIOS. Refer to the illustration below. If you are upgrading from a V1 2120 to a V2 2120, then the Upgrade Kit 74058 can be used - this includes the new BIOS.

LCD Board Remove and replace the LCD using the method described for the Main PCB.

Membrane Keypad Remove the Main PCB and LCD as described above. Carefully peel off the old keypad, which is held in place by adhesive backing on the keypad. Remove any remaining adhesive material from the case before fitting the replacement. A protective film sheaths the new keypad and when removed will expose the adhesive. Slot the tail of the keypad through the opening provided in the case and kneed the keypad into place.

Battery Pack Dismantle the Vitalograph 2120 as described in Section E. Unclip the battery pack from the case lower and replace with the new one.

Fleisch Element Assembly Dismantle the Vitalograph 2120 as described in Section E. It is recommended that new ‘O’ Rings be used with the new Fleisch Element Assembly. Lightly grease three of the new ‘O’ Rings and manoeuvre them into the inner three slots of the element. Fit the remaining un-greased ‘O’ Ring to the outer slot. Ensure holes and grooves are free of grease or dirt. Take care not to cut ‘O’ Rings when replacing the element assembly into the flowhead body.

Flowhead Seal Kit Dismantle the Vitalograph 2120 as described in Section E. Remove the old ‘O’ Rings from the Fleisch Element Assembly. Lightly grease three of the new ‘O’ Rings and manoeuvre them into the inner three slots of the element. Fit the remaining un-greased ‘O’ Ring to the outer slot. Ensure holes and grooves are free of grease or dirt. Take care not to cut ‘O’ Rings when replacing the element assembly into the flowhead body. The Vitalograph 2120 ‘O’ Rings are autoclaveable and need only be replaced after 50 autoclaves.

BIOS Prom The BIOS is the low level software for the 2120 i.e. does the interacting with the hardware. If the BIOS prom is ever required to be upgraded, dismantle the Vitalograph 2120 as described in Section E. The BIOS prom is the labelled 32 pin PLCC package device socketed on the Main PCB. Remove this IC using a suitable extraction tool. Refit the socket with the new BIOS prom. The BIOS used with version 1.xx software is 74200. The BIOS used with version 2.xx software is 74201.

Cradle PCB Dismantle the cradle as described in section E. Remove the four holding screws and lift the PCB assembly clear of the unit.

Software Note: If there upgrading software requires an upgrade kit (e.g. upgrading from version 1.xx to version 2.00), read the supplied instructions with that kit very carefully. Software upgrades are made via a PC and the serial cable. Connect the 9 Way D Type end of the serial cable to a COM port on the PC. Connect the modular plug to the Vitalograph 2120.

Installation: CODELOAD for Windows is currently distributed as a standalone executable without an installation program. However, it is simple to set up. 1.

Create a directory called, say, "Loader".

2.

Copy the contents of the floppy disk into this directory.

3.

Create a directory for each of the 2100 series devices supported by the code-loading software e.g. C:LOADERV2120

4.

Within each directory, create a directory for each version of the software which is supported. These variant subdirectories should have names corresponding to the Part No. and version for the software. e.g. C:LOADERV212074210-1.13

Copyright Vitalograph 2001& 2002

5.

Each variant of the software will be supplied as a set of "HEX" files and a "CLD" file. Copy these files into the variant directory.

Run Sequence: 1.

Connect the cabling to one of the free COM ports of the PC. Attach the power supply to the cabling if required.

2.

Run CODELOAD.EXE.

3.

There are 3 options, ACTION, OPTIONS and ABOUT.

4.

Select OPTIONS. Ensure 'Port Settings' corresponds to the COM port to which the device is attached.

5.

Select the PRODUCT option. This allows the user to select a set of "HEX" files to be loaded to the device. Select the appropriate directory and select the corresponding "CLD" file. The application now copies the "HEX" files into the application directory. This prevents undue traffic when loading files across a network. Any previous "HEX" files in the application directory are deleted.

6.

Select the FILES option. When a version of software is selected, all files are selected by default. The "FILES" dialog gives the user the opportunity to select only the files which are to be loaded.

7.

Select the ACTION menu item and then select START UPLOADING. This brings up a dialog which remains active until the user has completed loading all units.

8.

Attach the unit and put it into "FILE UPLOAD" mode. This is done by pressing the Up and DOWN arrow keys when switching the 2120 on.

9.

When ready to upload, select the START button. The uploading progress is displayed on the dialog. Uploading takes up to 10 minutes, depending on the number of files selected.

10.

When all units have been loaded, simply select the EXIT button to leave the uploading dialog. The units are rebooted immediately after the code has been loaded.

11.

To exit CODELOAD for Windows, simply select ACTION - EXIT.

Programming Units With Their Serial Numbers: A 5 digit Unit ID ( Serial # ) must be sent to the 2120 using codeload Version 3.00 or greater if the 2120 is to be used with 2170 Spirotrac Version 4. A communications error message will appear on 2170 Spirotrac V4 if it tries to communicate with a 2120 version 2.00 with no ID loaded. Use the following sequence to program 2120s with serial numbers:1.

When loading units with software, the serial number of the unit can be programmed into the unit afterwards, by clicking on the SEND UNIT ID AFTER LOAD checkbox.

2.

Click on the SEND ID button and enter the unit ID in the box provided.

3.

Perform codeloading as normal - ref. section C above. The ID will be sent to unit after the software is loaded.

4.

If an ID is to be sent to a unit with software already on it, simply perform step 2 and click OK - the unit must be in its main menu. This is only applicable to Version 2.00 software and after.

Resetting Unit: To reset the unit (i.e. return to factory defaults and clear database) do the following:1.

Switch off the unit.

2.

Switch on the unit.

3.

While the startup screen is showing, press the "DEL" key. The unit displays a screen which prompts for a confirmation that the user wishes to reset the unit.

4.

Press ENTER.

The unit now resets itself. DO NOT SWITCH OFF THE UNIT UNTIL THE STARTUP SCREEN IS DISPLAYED!! DOING SO MAY RENDER THE UNIT INOPERABLE !! Note:- The date and time should be reset after resetting the unit and the unit should be calibrated.

Definitions of cleaning and disinfection are as defined in “Sterilization, Disinfection and Cleaning of Medical Equipment: Guidance on Decontamination from the Microbiology Committee to Department of Health Medical Devices Directorate, 1996” Recommendations for chemical disinfectants are derived from the PHLS publication “Chemical Disinfection In Hospitals” 1993. Clean each separate part of the flowhead by washing in a mild detergent to remove particulate contamination. To clean the Fleisch element, swill vigorously in water with mild detergent. Do not attempt to “rub” or “scrub” at capillaries. If the flow conditioning meshes appear dirty or blocked they should be thrown away and replaced. Rinse with clean water. Disinfect by immersion in sodium dichloroisocyanurate solution at 1000 ppm concentration of free chlorine for 15 minutes. Prepare disinfectant solution as directed in the manufacturer’s guidelines. Rinse with hot water to aid drying. Leave to dry completely before reassembling. Drying the Fleisch element assembly may require placing it in a warm place overnight. A drying cabinet is ideal, alternatively another heat source could be used. Wiping with a 70% Isopropyl Alcohol impregnated cloth provides a suitable form of cleaning and low-level disinfection for the case exterior, display, and keypads. Repeat at least weekly to prevent build-up of grime from normal handling and use. Always follow the safety guidelines given by the manufacturer of cleaning and disinfectant chemicals or equipment.

Hygiene It is vital for the user to set guidelines for protective hygiene measures whilst using the Vitalograph 2120. There are three main potential sources of cross contamination, skin contact; aerosolised particles and saliva/body fluids. By far the most important is the last item – a minimum requirement is to use a new disposable mouthpiece for each subject tested. We recommend using the SafeTway mouthpiece for expiratory tests or the Bacterial/Viral Filter for testing involving inspiratory and expiratory manoeuvres. We also recommend that a delay of at least 5 minutes be allowed between subjects. This allows aerosolised organisms to be removed by gravitational sedimentation between tests.
