1.3 Warnings
Warning :
1) Explosive hazard—DO NOT use the device in environment with flammable gas such as some ignitable
anesthetic agents.
2) DO NOT use the device while the user is being scanned by MRI or CT.
3) .The person who is allergic to rubber can not use this device.
4) The disposal of scrap device and its accessories and packing (including battery, plastic bags, foams and paper
boxes) should follow the local laws and regulations.
5) Please check the packing before use to make sure the device and accessories are totally in accordance with
the packing list, or else the device may have the possibility of working abnormally.
7) The uncomfortable or painful feeling may appear if using the device ceaselessly. It is recommended that the
sensor should not be applied to the same finger for over 2 hours.
8) The SpO probe can not be clipped on the edema and tender tissue.
2
9) The infrared is harmful to eyes, so the user and the maintenance man should not stare at the light part of the
SpO probe (the infrared is invisible).
2
10)User can not use fingernail polish, fake nails or other makeup.
11)The fingernails of the User should not be too long.
13)The device is not intended for treatment.
14) 1.4 Attention for operation
a. Please check the device before using, and confirm that it can work normally.
b. The finger should be placed properly (see the attached illustration of this manual, Figure 1), or else it may cause
inaccurate measurement.
c. The SpO sensor and photoelectric receiving tube should be arranged in a way with the subject's arteriole in a
2
position there between.
d. The SpO sensor should not be used at a location or limb tied with arterial canal or blood pressure cuff or
2
receiving intravenous injection.
e. Make sure the optical path is free from any optical obstacles like rubberized fabric.
f. Excessive ambient light may affect the measurement result. It includes fluorescent lamp, dual ruby light,
infrared heater, direct sunlight etc.
g. Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy.
h. User can not use fingernail polish, fake nails or other makeup.
i. Please clean and disinfect the device after operating according to the User Manual (6.1.1)
j. The Pedometer should be worn on the waist, and fixed well.
1.5 Clinical restrictions
1. As the measure is taken on the basis of arteriole pulse, substantial pulsating blood flow of subject is required.
For a subject with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of vascular
contracting drug, the SpO waveform (PLETH) will decrease. In this case, the measurement will be more
2
sensitive to interference.
2. For those with a substantial amount of staining dilution drug (such as methylene blue, indigo green and acid
indigo blue), or carbon monoxide hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin,
and some with icterus problem, the SpO determination by this monitor may be inaccurate.
2
3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for
serious error of SpO measure.
2
4. As the SpO value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some users
2
with serious anemia may also report good SpO
Notice
The product is not suitable for use in continuous supervision for the user.
The problem of overrating would emerge when the user is suffering from toxicosis which caused by
carbon monoxide, the device is not recommended to be used under this circumstance.
2 Principle
2.1 Operation principle for Pulse Oximeter
Figure 1 Operating principle
Principle of the Oximeter is as below: An experience formula of data process is established taking use of Lambert
Beer Law according to Spectrum Absorption Characteristics of Reductive Hemoglobin (Hb) and Oxyhemoglobin
(HbO ) in glow & near-infrared zones. Operation principle of the instrument is: Photoelectric Oxyhemoglobin
2
Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording Technology, so that
two beams of different wavelength of lights can be focused onto human nail tip through perspective clamp
finger-type sensor. Then measured signal can be obtained by a photosensitive element, information acquired
through which will be shown on screen through treatment in electronic circuits and microprocessor.
2.2 Operation principle for Pedometer
The Pedometer, basing on counting steps by acceleration sensor, adopts the recognition principle of pace waveform
and its acceleration and deceleration process for recognizing the waveform produced by person walking, finally
gets the number of steps. Detailed method: use the acceleration sensor to collect user's steps(more than three steps),
via analyzing and calculating, obtain the peak value of step vibration waveform and the average value of
acceleration difference value, and set it to the threshold value. Collect the user's actual step waveform data, if it is
in the threshold range, then it is considered that user walks one step forward.
