1. PRECAUTIONS
The following information is provided to help the user operate the pump safely and accurately and further prevent safety hazard or physical injuries or damage.
DANGER
1. Keep the pump away from inflammable anesthetic. WARNING
1. Make sure that an inlet that is connected to the external power stays dry all the time.
2. Do not use a mobile phone, radio set or defibrillator generating high frequency near the pump.
3. Do not use this pump in MRI rooms, high-pressure rooms or places while high electromagnetic radiation is generated.
4. Be sure to set the infusion set rightly. If it is set by a reversed manner to a normal pump operation, the patient’s blood will be drawn up into the tubing.
CAUTION
1. Operate the pump by the designated steps.
2. When the external power sources are used, keep in mind the following matters: 1) Use the power cord for the hospital and plug it into the grounded outlet. 2) Prior to use, check the rated voltage and frequency.
3) Be sure to check whether an extension cord is normal or not. 3. Use only the person educated about the pump or a skilled hand.
4. Attach the pump securely to an infusion stand and ensure its stability. If the pump is dropped or given any hard shocks, do not use it. Please call the local agencies or the company.
5. During infusion, frequently check the infusion line such as a rupture in the filter or a leak in the line. Check both pump and patient’s conditions on a regular basis while drugs are infused. To ensure a good connection between the patients with the infusion line, a male-to-female luer-lock type connection is recommended.
1. PRECAUTIONS
CAUTION
6. Pay close attention to the following matters when the infusion set is used.
1) Use a designated infusion set for infusion pump. If any infusion set other than specified is used, proper flow rate accuracy and alarm function (air and occlusion) are not guaranteed. If the designated set is not available, contact to the agent or company.
2) Do not pull on the tubing with excessive force. Then the intended flow rate may not be achieved.
3) Fit the tubing inside of the door from bottom to the top. Securely set the tubing
along the groove of the PUMPING UNIT ○31. If not, free flow or leak can be
occurred.
4) Do not connect an infusion set administrated from an infusion pump to another infusion line administrated only by the manual roller clamp (gravity infusion) because this may influence the accuracy of infusion and alarm functions.
5) When drugs are infused for extended time, change the tubing location once every 12 hours to use the tubing within the margin of errors.
6) Do not reuse the infusion set.
7. When the pump is operated under the shown description conditions, the flow rate accuracy may be incorrect.
1) Using drugs of the higher viscosity such as Dextrose 50%.
2) Operating under an ambient temperature between +5 ℃ and 40 ℃, a relative humidity between 20% and 90%.
8. Pay attention to the following matters when the pump operates on battery.
1) Check the battery use time. (The battery can be used for 2 hours at flow rate 25ml/h if it is fully charged.)
2) Connect the main power to charge the battery if the indicator that displays
LOW BATTERY ALARM INDICATOR ○21 on the front is turned on or the alarm
sounds.
3) Charge the internal battery to full capacity by connecting the pump to an AC power supply for 15 hours at least.
4) When the external (AC/DC) power is supplied, 3 lamps of the Battery capacity indicator ○17 will be turned on without regard to the battery capacity.
1. PRECAUTIONS
CAUTION
9. Never connect both AC and DC power sources to the infusion pump at the same time. To use the DC power, be sure to check the polarity of the DC jack.
10. Do not sterilize the pump with autoclave or E.O. gas. Do not wipe the pump with thinner, solvent, benzene, ammonia, acetone, etc. Use a wet cloth to clean.

5. THEORY OF OPERATION
5. THEORY OF OPERATION
5.2 POWER SUPPLY PART
Power supply part consists of SMPS and 5V regulator, battery, and battery charger. The AC power inputs into inlet with EMC/EMI filter. SMPS converts from DC power. Whenever the SMPS is activated by AC power, the AC/DC indicator on the front is lit. SMPS (Switching Mode Power Supply) converts AC power (100~240VAC, 50/60Hz) into DC power (15VDC, 2.3A). The SMPS has over-voltage and over-current protection. Two 3.15A slow blow replacement fuses are required for AC. Battery charger will charge the battery as long as the pump is connected to a specified AC power. 5V regulator circuit on the main rear board generates 5V(Vcc) for electronic components from the output of SMPS and internal battery.
5.3 CPU PART
CPU part consists of controller (CPU) and EPROM, EEPROM, address decoder and oscillator, reset circuit. The controller (CPU) controls all pump function and gather data from the key controller, A/D converter, EEPROM and alarm controller. The controller utilizes 16-address line and 8 data line. Program reserved at the EPROM make the system work and main data will be maintained at the serial EEPROM. Oscillator generates 12MHz clock and pulse divider generates a pulse for the A/D converter.
5.4 KEY CONTROL PART
Key control part consists of keypad and key controller. The key is multiplexed 4 x 4 array, which is scanned by key controller. One of 4 select lines determines which four keys are read. All normal key depressions are decoded by this matrix.
5.5 DISPLAY PART
Display part consists of display controller and two 7-segments with 4digits and several LED. Two-display controller manages display and displays are turned on in order. Alarm/operation indicators are managed by the controller, while AC/DC indicator is managed by its own circuit.
5. THEORY OF OPERATION
5.6 MOTOR CONTROL PART
Motor control part consists of motor, motor driver and rotation detector. The motor adopts bi-polar stepping motor to precise control and is controlled by 1/8, 1/4, 1/2 micro step control in order to precise than control. The motor is shut down when an alarm or failure occurs. The motor speed range permits infusions from 1 to 999 ml/h. The motor rotation detector assures that pump drive rotation occurs or the motor shuts down. CPU reads the motor rotation signal via the sensor controller. 5.7 SENSOR
1) Air sensor part
The air sensor part consists of an ultrasonic transmitter and receiver mounted on opposite sides of the tubing path. The transmitter consists of an oscillator and piezo ceramic that transform electric energy into mechanical energy. The transmitter consists of signal process part and piezo ceramic that transform mechanical energy into electric energy. The transducers operate on the principle that air in the tubing transmits ultrasonic energy much less effectively than fluid. This energy is amplified, rectified, applied to the A/D converter and than converted into a digital signal. The CPU monitors the signal and activates an AIR alarm if it detects the absence of a level energy.
2) Occlusion sensor part
The down and up stream occlusion sensor consists of a moving magnet and hall sensor that detects magnet. As the condition of infusion set, up and down of magnet, which is tangled by the end of occlusion is sensed by hall sensor. The moving magnet is spring-loaded against the tubing, when pressure down stream of the pump increase, the magnet moves from its original position, which in turns change the voltage of the sensor. If the occlusion is sufficient to cause a specific voltage change, the CPU activates an alarm.
There is a maximum expansion of the tubing beyond which the pump will no longer permit operation.
3) Low battery detector
The input voltage is sensed by step-downed in use of resistance. The alarm works when the voltage goes down under base line. When the voltage goes below impracticable figure, the display and motor stop.
4) Door Open Sensor
When the door is opened, the drop in voltage that is sensed by the distance between the magnet stuck to the door and hole sensor. After all, the alarm works.
