    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.
  • Page 16 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.
  • Page 17 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.
  • Page 18 all three battery level indicators will be turned on, and the AC/DC indicator will be turned on. 6) Plug in again and check whether the device is operated without problems. Repeat 3) and 4) above. 7) As the pump continues infusion, the battery level indicators will be turned off one after another and eventually the battery low alarm will sound.

  • Page 21: Operating Mechanism

    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.
  • Page 22 The inlet and the SMPS have a separate fuse (250V T3.15) to prevent sudden over- current. 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.
  • Page 23 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.
  • Page 24 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. Electrical Wiring Inspection 5.1. SMPS 1) Check the wiring between Connector CN81 and the power inlet. 2) Check the wiring between Connector CN91 and Connector J5 of the main board. 5.2. Main board 1) Check the wiring between Connector J1 and Connector J1 of the checker. 2) Check the wiring between Connector J4 and EXT Power Switch.
  • Page 26 2) Check the wiring between Connector J4 and FFC (Flexible Flat Cable) of Connector J7 of the main board. 3) Check the wiring between Connector J6 and Connector J1 of the door. 4) Check the wiring between Connector J7 and Connector J1 of the air sensor. 5) Check the wiring between Connector J8 and speaker.
