1.3 Warnings

Warning :

1) Explosive hazard—DO NOT use the device in environment with inflammable gas such as some ignitable

anesthetic agents.

2) DO NOT use the device while the testee is being scanned by MRI or CT.

3) In optical treatment, please follow doctor requirement to use the device.

4) DO NOT strand the lanyard in order to avoid device drop and damage. The lanyard is made of insensitive

material. Please do not use it if any person is allergic to lanyard. Do not wrap the lanyard around neck to avoid

an accident.

5) The person who is allergic to rubber can not use this device.

6) 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.

7) 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.

8) Please don't measure this device with function tester for the device's related information.

9) The uncomfortable or painful feeling may appear if using the device ceaselessly, especially for the

microcirculation barrier patients. It is recommended that the sensor should not be applied to the same finger for

over 2 hours.

10) The SpO2 probe can not be clipped on the edema and tender tissue.

11) The infrared is harmful to eyes, so the user and the maintenance man should not stare at the light part of the

SpO2 probe (the infrared is invisible).

12) Testee can not use enamel or other makeup.

13) The fingernails of the testee should not be too long.

14) For the details of correlative clinic restriction and contraindications, please refer to the related medical

literatures.

15) The device is not intended for treatment.

16) The device is a medical device, and it can be used repeatedly.

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 SpO2 sensor and photoelectric receiving tube should be arranged in a way with the subject’s arteriole in a

position there between.

d. The SpO2 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

2 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

2 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 SpO2 measure.

4. As the SpO2 value serves as a reference value for judgement of anemic anoxia and toxic anoxia, some patients

with serious anemia may also report good SpO

2 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.

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

(HbO2) 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.

5.2 Data measurement

1) Install the two “AAA” batteries properly, then the device will turn on automatically and enter to

“Synchronous Time...” interface.

Figure 8 Synchronous time interface

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 time 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

2” 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 SpO2 and pulse rate value directly from the screen after inserting the finger for about 4~8 s, shown as

Figure 3. Pull out the finger after stable data appears to finish data storing. Only one result is stored from

each inserting to pulling out the finger.

5) In SpO2

state, screen direction can be changed automatically.

6) The interface between “Steps” and “SpO2” interface can be switched by inserting the finger.

a. In “Steps” interface, insert the finger to enter to “SpO2” interface.

b. In “SpO

2” interface, pull out the finger to enter to “Steps” interface, shown as Figure

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.
