OPERATOR’S MANUAL
Pulse Oximeter ri-fox N
ENGLISH

General Description
Oxygen Saturation is a very important parameter for the Respiratory Circulation
System. Many respiratory diseases can result in oxygen saturation being lowered in
human blood. Additionally, the following factors can reduce oxygen saturation: organ
dysfunction caused by anesthesia, intensive postoperative trauma, injuries caused by
some medical examinations. That situation might result in light-headedness, asthenia,
and vomiting. Therefore, it is very important to know the oxygen saturation of a patient
so that doctors can nd problems in a timely manner.
The fingertip pulse oximeter ri-fox N features small size, low power consumption,
convenient operation and portability. It is only necessary for a patient to put one of his
ngers into the ngertip photoelectric sensor for diagnosis, and a display screen will
show oxygen saturation. It has been proven in clinical experiments that it also features
high precision and repeatability.

Product Operation Scope
Technical Specications
ri-fox N is a portable non-invasive, spot-check, oxygen saturation of arterial hemoglobin
(SpO2) and pulse rate of adult and pediatric patients at home and hospital (including
clinical use in internal medicine/surgery, anesthesia, etc). The device is not intended for
continuous monitoring.
The ri-fox N requires no routine calibration or maintenance other than replacement of
batteries.

3. Pulse Rate:
Measure range: 30~235 bpm
Accuracy: 30~100bpm ±2bpm; 101~235bpm, ±2%

7. Measurement Performance in Low Perfusion Condition: The pulse wave is
available without failure when the simulation pulse wave amplitude is at 0.6% using
the test equipment (Biotek Index Pulse Oximeter Tester).
8. Interference Resistance Capacity against Ambient Light: Device works normally
when mixed noise produced by Biotek Index Pulse Oximeter Tester.

1. Do not use the pulse oximeter in an MRI or CT environment
2. Do not use the pulse oximeter in situations where alarms are required. The device
has no alarms.
3. Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
4. The pulse oximeter is intended only as an adjunct in patient assessment. It must be
used in conjunction with other methods of assessing clinical signs and symptoms.
5. Check the pulse oximeter sensor application site frequently to determine the
positioning of the sensor and circulation and skin sensitivity of the patient.
6. Before use, carefully read the manual.
7. ri-fox N has no SpO2alarms; it is not for continuous monitoring, as indicated by the
symbol.
8. Prolonged use or the patient’s condition may require changing the sensor site
periodically. Change sensor site and check skin integrity, circulatory status, and
correct alignment at least every 4 hours.
Precautions for use
- 4 -

9. Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing,
or immersing the sensors in liquid may cause inaccurate readings.
10. SpO2measurements may be adversely affected in the presence of high ambient
light. Shield the sensor area if necessary.
11. Excessive patient movement may cause inaccurate readings.
12. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter,
or intravascular line may cause inaccurate readings.
13. Fingernail polish or false ngernails may cause inaccurate SpO2readings.
Contraindication
14. Signicant levels of dysfunctional hemoglobins (such as carbonxy-hemoglobin or
methemoglobin) may cause inaccurate readings
15. Intravascular dyes such as indocyanine green or methylene blue may cause
inaccurate readings
16. Venous pulsations may cause inaccurate readings.
17. Hypotension, severe vasoconstriction, severe anemia or hypothermia may cause
inaccurate readings.
18. Cardiac arrest or shock may cause inaccurate readings.
No side effects known
Follow local ordinances and recycling instructions regarding disposal or
recycling of the device and device components, including batteries.

1. Easy to use.
2. Small in volume, light in weight.
3. Low power consumption.
4. Low voltage warning will be indicated in visual window when battery voltage is low.
5. The product will automatically be powered off when no signal is registered for longer
than 8 seconds.
1. Install two AAA batteries into the battery cassette, and then close its cover.
2. Open the clamp as shown in the picture below.
3. Insert one nger completely into the opening of the pulse oximeter.
4. Press the power switch once on the front panel.
5. The patient’s nger should remain still while the pulse oximeter is working.
6. Read corresponding data from display screen.
When you insert a nger into the Oximeter,
your nail surface must be upward.

The Pulse Bar graph displays the strength of the pulse rate signal. The height of the
bar graph shows the patient’s pulse strength.
1. Put the two AAA batteries into battery cassette in correct
polarities.
2. Press the button down along the arrow and push the
battery cover shown as below:

1. Replace batteries in time when low voltage lamp is lighted.
2. Clean surface of the ri-fox N before it is used in diagnosis for patients.
3. Remove batteries inside the battery cassette if the oximeter will not be used for a
long time.
4. It is best to preserve the product in a place where ambient temperature is –20~55°C
and humidity is <93%, no condensation.
5. It is recommended that the product should be kept in a dry environment anytime. A
wet ambient might affect its lifetime and even might damage the product.
6. Please follow the law of the local government to deal with used batteries.
1. The functional tester cannot be used to assess the accuracy of the oximeter.
2. The test method used to establish the SpO2accuracy is clinical testing. The
oximeters used to measure the arterial haemoglobin oxygen saturation levels are
compared to the levels determined from arterial blood sampling with a CO-oximeter.
3. Index 2 that is made by Biotek company is a function tester. Set Tech to 1, R curve
to 2, and then users can use this particular calibration curve to measure the
oximeter.
