1. Introduction 1.1 Overview This manual provides technical descriptions on MedifusionⓇ DI-2000 Volumetric Infusion Pump for hospitals' medical equipment technicians or person authorized by Daiwha Corporation for maintenance of the equipment. For more details on how to use the equipment, see the user manual.

1.2 Product Overview MedifusionⓇ DI-2000 Volumetric Infusion Pump is a medical instrument that injects a certain amount of drug into patients through the infusion set at the rate selected by the patient. The pump consists of the semi-transit linear peristaltic infusion part that infuses drug at a certain rate by the program and the circuit part that controls the infusion part.

The pump can be used with power supply of 50/60Hz between 100 and 240 VAC and includes self-charged built-in battery. The pump can be used in motion, and the infusion set designated for the pump is recommended. Make sure that the set is equipped with Luer lock adapter when drug is infused by central line catheter.

Available flow rates are 99.9 ml/h at 0.1 and 1,200ml/h at 100. Infused volume can be displayed between 1 and 9999 ml. When the total volume is set to infinite, the infused volume will be displayed as 0 at 9999 ml. Once the set volume is all infused, the pump will be automatically changed to Keep Vein Open (KVO) rate. The pump will stop infusion anytime when the stop key is pressed.

3. Inspection Procedures

In order to prevent sudden problems of Infusion Pump DI-2000 and ensure safe use, monthly inspections need to be carried out in accordance with the following procedures.

3.1. Power Supply Inspection 1) Connect the infusion pump to the external power. Make sure that the infusion set is not mounted and the door is closed. 2) Check whether the AD/CD indicator is on. 3) Turn on the power switch on the rear side of the pump. 4) Check whether the three batter level indicators on the front panel are all illuminated. 5) Disconnect the external power supply and check whether the AC/DC indicator is off. Also, check whether at least one battery level indicator is illuminated. 6) Connect the external power supply again and check whether the AC/DC indicator is illuminated.

3.3. Dropping Test 1) Turn on the power. 2) Fill the infusion set with a solution and remove air inside the tube. Make sure that the infusion set container is filled to the half level so that dropping of solution drops can be checked. 3) Open the door and mount the infusion set to fit the sensors and the pumping unit. 4) Mount the infusion set into the device such that the distance between the top of the pump and the solution bottle mouth is about 1 meter. Keep the infusion set clamp closed. 5) Close the pump door and open the infusion set clamp. Observe for 60 seconds whether the solution is dropping from the end of the set. 6) Open the pump door and lower the pumping unit lever to open the pumping unit. Once free drops are generated, close the door. Leave the pump for one minute and check for one minute whether drops are generated from the end of the infusion set.

3.4. Accuracy Test 1) Turn on the power and mount the infusion set without air bubbles and clogging in the tube. 2) Set flow rate and total volume to 100 ml/h and 100 ml respectively. 3) Check whether the flow rate and the total volume are set to 100 ml/h and 100 ml respectively and make sure that the infused volume is 0 ml. Otherwise, set the infused volume to 0 in the infusion mode. 4) Start infusion by pressing the START key. Make sure that air bubbles or clogging would not occur during infusion. 5) When the infusion completion alarm sounds when infusion is completed, stop infusion by pressing the STOP key. Check infusion time (1 hour) and infused volume (100 ml).

3.5. Door Open Alarm Test 1) Turn on the power and mount the infusion set without air bubbles and clogging inside the tube. 2) Open the door and check whether the door open indicator is illuminated. 3) Start infusion by pressing the START key. Check whether the door indicator blinks with an alarm sound. 4) Press the STOP key and check whether the alarm is off. Check whether the door open indicator is still illuminated. 5) Close the door and check whether the door open indicator is turned off. 6) Press the START key to start infusion. Check whether the infusion indicator blinks. 7) Open the door again and check whether the infusion indicator stops blinking and the door open indicator blinks. 8) Close the door and press the STOP key to stop the alarm sound.

3.6. Air Alarm Test 1) Turn on the power and mount the infusion set without air bubbles and clogging inside the tube. 2) Start infusion by pressing the START key. Check whether the STOP indicator is turned off and the infusion indicator blinks.

3) Create air bubbles intentionally inside the tube and make them flow into the pump. 4) Check whether the air indicator blinks and alarm sounds when air bubbles reach the air sensor. The infusion indicator stops blinking, and the stop indicator is turned on. 5) Press the STOP key and check whether the alarm sound stops and the air indicator is still illuminated. 6) Open the door and remove air bubbles from the air sensor. Mount the infusion set again. 7) Close the door and check whether the air indicator is turned off.

3.7. Occlusion Alarm Test 1) Turn on the power and mount the infusion set without air bubbles and clogging inside the tube. 2) Start infusion by pressing the START key.

4. Operating Mechanism 4.1 Block Diagram

4.2. Power Supply The SMPS (Switching Mode Power Supply) changes AC phase current (100-240 VAC, 50/60 Hz) to DC current (24VDC, 1A) and charges the built-in battery. Through the regulator inside the main board, it generates 3.3 V for each electronic element and 5 V for the air sensor and displays.

The built-in battery is used as an emergency power supply when AC power supply is disconnected. The phase power is provided from the inlet with an EMC filter. It is rectified by the SMPS and switched to DC power. The AC/DC power supply LED is illuminated regardless of the power switch, and the built-in battery is automatically charged. When the phase power is disconnected, the built-in battery is automatically on, supplying power to each circuit ceaselessly.

The inlet and the SMPS have a separate fuse (250V T3.15) to prevent sudden overcurrent. Also, the SMPS has a feature to prevent over-current and over-voltage. The main power supply is provided to each part by the SMPS as 24V/1A power and used to recharge the built-in battery. The power supply is divided by the regulator into 24V for the motor and 5V and 3.3V for circuits.

4.3. Main Board The main board is composed of memory that stores MCU and the program, EEPROM that stores data, the source program that controls each part, MCU oscillator that is the basis of all signals, and the reset circuit that initializes MCU.

All system signals are controlled by 8-bit MCU, and signals required for control are sent to parts or received by the address decoder. The clock pulse of MCU is supplied with 8MHz at the oscillator part and provides pulse for the A/D converter by the pulse dispenser. The program is embedded in the memory and drives the pump. Major data are stored in EEPROM and preserved semi-permanently even if power supply is disconnected.

4.4. Key Controls The key controls are structured as the key matrix of tact switches. Signals input by pressing each key are received by the MCU port and processed by scanning keys. For keys input properly, proper operations are carried out.

4.5. Displays The display part consists of the controller, 4-digit 7 segments, and LED. The displays are controlled by three display controllers and divided into flow rate display and other displays. Each digit of 7 segments is illuminated sequentially to display one after another. Warning lights and indicators, battery level indicators, and AC/DC indicator are controlled and illuminated by MCU.

4.6. Motor Control

Motor control is composed of motor, motor driver, and motor checker. For precise control, uni-polar stepping motor was adopted and 1/16 micro step control is carried out through the motor driver for more precise control.

A motor checker is attached to the pumping unit axis, which is sensed by the interrupt switch to check operation of the pumping unit (or motor) and to calculate infused amount. For detection of the pumping unit backlash and quick infused amount error compensation, a dual pattern checker is used. The number of rotations of the pumping unit is identified by comparison with the number of pulses input to the motor. Low or high rotation of the pumping unit is also detected.

4.7. Sensors 1) Air sensor The air sensor transmitter is composed of the oscillator that generates oscillation signals of ceramic and piezo ceramic that changes the electric signals into mechanical vibration. The receiver has piezo ceramic that changes mechanical vibration into electric signals. The signals are amplified, rectified by the diode, and provided to the A/D converter. If air bubbles pass in the set between the two piezo ceramics, transmission of ultrasonic waves will be interrupted and voltage will drop. This is sensed and alarm sounds. This feature also senses an empty infusion set.

2) Occlusion sensor The occlusion sensor detects clogging or expansion inside the infusion set by means of the hall sensor. The occlusion device moves up and down, and the sensor's output voltage varies depending on the device movement. When output voltage fluctuates beyond a certain value, warning sound is generated. Also, the occlusion device can be used to check whether or not the infusion set is mounted.

3) Battery low sensor The input power is monitored by the monitoring IC, and the current power level is measured and sent to MCU. If voltage drops below a certain level, warning sound is

generated. If voltage declines to a level that the device cannot operate, the display is turned off and the motor stops.

4) Door open sensor When the door is opened, the distance between the magnet attached to the door and the hall sensor is widened and voltage drop is sensed, generating a warning sound.

5) Drop sensor (optional) Liquid drops falling from the chamber of the infusion set are sensed by the photoelectric sensor. When free drops (solution drops that fall by the force of gravity, not controlled by the device) are generated, the pump generates a warning sound. For error compensation, the infusion set needs to be set clearly before the drop sensor is used given that the amount of one drop varies depending on infusion sets.

8. Disassembly and Adjustment

Only some part of Infusion Pump DI-2000 can be disassembled and replaced. The warranty shall not apply to disassembly or repairs arbitrarily carried out. Reassembly can be conducted in the reverse order of disassembly. Disconnect the external power supply before disassembly, and leave the power switch off. Since the electronic elements of the infusion pump are sensitive to electrostatic discharge, disassembly should be conducted on the antistatic workbench.

8.1. Separation of Case-Front from Case-Rear (See 9.2.) 1) Remove the bolts from the rear case with power off. Ensure that the front case should not be damaged by other elements. 2) Lift the rear case to separate the front part from the rear part. 3) When disassembling, make sure that the battery pack will not be separated or damaged and that the O-ring will not be lost. 4) When reassembling, ensure that the connector of each cable should be placed correctly. 5) When reassembly is completed, carry out electric safety test and make sure that the device is working normally.

8.2. Separation of Case-Front from Base Frame (See 9.4.) 1) Open the door and remove the bolt on the front. 2) Separate door latch, pumping unit, and door. 3) Remove the base frame bolt and separate the flat cable from the main PCB before complete separation from the front. 4) Make sure that PCB components will not be damaged when the battery pack is separated. 5) Be careful of the location of the plate spring when reassembling.

8.3. Replacement of Main PCB Ass'y (See 9.5.) 1) Separate the case-front from the base frame completely.

2) Remove the bolt fixing the main PCB and separate PCB by removing the cable connected. 3) Be careful about organization of cables when reassembling.

8.4. Separation of Pumping Unit (See 9.6.) 1) Lift the hook of the finger cover to separate the finger case. 2) Make sure that the spring is mounted properly when reassembling. 3) Coat grease on the working surface when reassembling.

8.5. Separation of Door (See 9.7.) 1) Remove the door pin to separate the auxiliary door. 2) Separate the auxiliary door and the presser block while taking precautions against dislocation of the spring. 3) After removing the bolt, remove the door handle pin and then disassemble the door cover completely. 4) Make sure that the door upper seal is placed completely when reassembling. 5) Make sure that the spring will not be displaced when reassembling.

8.6. Replacement of Air Sensor Ass'y (See 9.8.) 1) Separate the case front and the base frame completely. 2) Separate the air sensor connector from the display PCB assembly and remove the bolt from the air sensor assembly. 3) Push the air sensor assembly to separate it from the case front. Be careful that the assembly is attached to the case front with silicon. 4) Put silicon on the adjoining part. 5) Once the air sensor assembly and the case front are assembled, leave them for one to two hours so that silicon is completely hardened.

8.7. Replacement of Occlusion Sensor (See 9.8.) 1) Separate the case front from the base frame completely. 2) Separate the connector from the display PCB assembly.

3) Remove the occlusion sensor assembly from the case front and separate the occlusion sensor PCB assembly.

8.8. Replacement of Door Sensor PCB Ass'y (See 9.8.) 1) Separate the case front from the base frame completely. 2) Remove the connector of the door sensor PCB assembly from the display PCB assembly. 3) Loosen the bolt and remove the door sensor PCB assembly. 4) Make sure that the bolt tap will not be damaged when reassembling.

8.9. Replacement of Motor (See 9.5.) 1) Separate the case front and base frame completely. 2) Separate the main PCB assembly. 3) Separate the pumping unit pulley and remove the timing belt. 4) Remove the fixing bolt to separate the motor and the dustproof JIG. 5) When reassembling, make sure that the timing belt will not be too loosened or tightened.

8.10. Replacement of Checker and Checker PCB Ass'y (See 9.5.) 1) Separate the case front and the base frame completely. 2) Separate the main PCB assembly. 3) Remove the checker PCB assembly connector from the main PCB assembly. 4) Remove the checker PCB assembly. 5) Loosen the checker bolt to separate the checker. 6) Make sure the checker and the checker PCB assembly will be placed correctly when reassembling.

8.11. Replacement of SMPS (See 9.5.) 1) Separate the case front and base frame completely. 2) Remove the cable from SMPS. 3) Loosen the bolt to separate SMPS.

4) Reassemble in the reverse order of disassembly. After replacing SMPS, check the ground wire connection.

8.12. Replacement of Power Inlet (See 9.5.) 1) Separate the case front and case rear completely. 2) Remove the cable from SMPS. 3) Loosen the bolt to separate the power inlet. 4) Remove the cable from the inlet. 5) Be careful about organization of cables when reassembling.

8.13. Replacement of Cam Ass'y (See 9.5.) 1) Separate the case front and base frame completely. 2) Remove the checker B/D and separate the pumping unit pulley. 3) Remove the bearing holder and separate the cam shaft. 4) Coat grease on the working surface when reassembling.

1.3 USBto Serial Adapter Drivers Installation 1.3.1 Installing CDM Drivers

To install CDM drivers for an FTDI device under Windows XP, follow the instructions below: - If a device of the same type has been installed on your machine before and the drivers that are about to be installed are different from those installed already, the original drivers need to be uninstalled. Please refer to the Uninstalling CDM Drivers section of this document for further details of this procedure. - Download the latest available CDM drivers from the FTDI web site and unzip them to a location on your PC. Goto: http://www.ftdichip.com/Drivers/VCP.htm - If you are running Windows XP or Windows XP SP 1, temporarily disconnect your PC from the

Internet. This can be done by either removing the network cable from your PC or by disabling your network card by going to the "Control Panel\Network and Dial-Up Connections", right-clicking on the appropriate connection and selecting "Disable" from the menu. The connection can be re-enabled after the installation is complete. This is not necessary under Windows XP SP 2 if configured to ask before connecting to Windows Update. Windows XP SP 2 can have the settings for Windows Update changed through "Control Panel\System" then select the "Hardware" tab and click "Windows Update". - Connect the device to a spare USB port on your PC. If the device is based on the FT2232, the Microsoft composite device driver is automatically loaded in the background. Once the composite driver has been installed Windows Found New Hardware Wizard will launch. If there is no available Internet connection or Windows XP SP 2 is configured to ask before connecting to Windows Update, the screen shown in Figure 1.2s displayed. Select "No, not this time" from the options available and then click "Next" to proceed with the installation. If there is an available Internet connection, Windows XP will silently connect to the Windows Update website and install any suitable driver it finds for the device in preference to the driver manually selected.

Figure 1.2 -Select "Install from a list or specific location (Advanced)" as shown in Figure 1.3 below and then click "Next".

Figure 1.3 -Select "Search for the best driver in these locations" and enter the file path in the combo-box ("C:\CDM 2.02.04" in Figure 1.4 below) or browse to it by clicking the browse button. Once the file path has been entered in the box, click next to proceed

Figure 1.4 -If Windows XP is configured to warn when unsigned (non-WHQL certified) drivers are about to be installed, the message dialogue shown in Figure 1.5 will be displayed unless installing a Microsoft WHQL certified driver. Click on "Continue Anyway" to continue with the installation. If Windows XP is configured to ignore file signature warnings, no message will appear.

Figure 1.5 -The screen shown in Figure 1.6 will be displayed as Windows XP copies the required driver files.

Figure 1.6 -Windows should then display a message indicating that the installation was successful (Figure 1.7). Click "Finish" to complete the installation for the first port of the device.
