council directive IEC 60601-1、IEC 60601-1-11 and

inaccurate measurement.

c. The SpO

sensor and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a

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

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 and etc.

g. Strenuous action of the subject or extreme electrosurgical interference may also affect the accuracy. h. Testee can not use enamel 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

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.

3. The drugs like dopamine, procaine, prilocaine, lidocaine and butacaine may also be a major factor blamed for

serious error of SpO

4. As the SpO

with serious anemia may also report good SpO

measure.

value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some patients

measurement.

Notice

The product is not suitable for use in continuous supervision for patients. The problem of overrating would emerge when the patient is suffering from toxicosis which caused by carbon monoxide, the device is not recommended to be used under this circumstance.

probe (the infrared is invisible).

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

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.

Notice

In “Synchronous Time...” interface, Bluetooth will be turned on automatically.

2) Three methods to exit from “Synchronous Time...” interface.

Notice

Before each measurement, make sure the device has been performed sync time, to insure accurate ti me for storing data. It indicates that the device needs to perform sync time when it displays “Synchronous Time...”, otherwise it will not store measurement results. The first method:

Don’t perform sync time, press the button, then the device will enter to “Steps” interface from “Synchronous Time...” interface.

The second method:

Don’t perform sync time, wait for several minutes, then the device will enter to “Steps” interface from “Synchronous Time...” interface.

The third method:

Perform sync time, connect to power, then the device will turn on automatically, when it enters to “Synchronous Time...” interface, connect it with App, then it will automatically adjust time.

3) In “Steps” interface, insert the finger to the probe (fully insert), then the device will automatically enter to

“SpO

” interface from “Steps” interface, shown as Figure 3.

Notice

 If the time is wrong, the device will not store data.  Fingernails and the luminescent tube should be on the same side.  During using, the testee’s finger should not shake, and keep quiet.

4) Read SpO

and pulse rate value directly from the screen after inserting the finger for about 4~8 s, shown as

Notice

In “Steps” interface, Bluetooth will be in “ON” state all the time.

7) In “Steps” interface for 1 minute, it will automatically enter standby mode.

Notice

In standby mode, the screen does not display any contents, but the pedometer can work normally. In standby mode, Bluetooth is in “OFF” state.

8) In standby mode, press Button to turn on screen display and enter to “Steps” interface shown as Figure 4.

5.3 Data upload

The device can transmit SpO

, pulse rate, Steps and calorie value to phone-side by wireless mode.

User can add the device by searching it in PC-side, as each device has the unique code which is marked in the device enclosure, which provides convenience for user to upload the results to PC, avoids confusion caused by excessive and same devices. After measuring, the device will automatically connect to the PC communicated with it last time. In “STEPS” interface, Bluetooth is in “ON” state, and it is in “OFF” state in other interfaces.

Notice

Before uploading steps data, please do sports for 5 minutes at least. The Pedometer can only upload the data(measured in the last day) on the next day.
