Fingertip Pulse Oximeter

Version number of this manual: V1.1

General Description

The measurement of oxygen saturation of arterial blood (also known as pulse
oxygen saturation, usually shortened as SpO2) adopts the principles of light
spectra and volume tracing. The LED emits lights with two specific wavelengths,
which are selectively absorbed by oxygenated hemoglobin and deoxyhemoglobin.
The optical receptor measures the changes in the light intensity after the light
passes the capillary network and estimates the ratio of oxygenated hemoglobin
and the total hemoglobin.

The mechanical activity of the heart cause arterial pulse, by measuring the pulse
we can get PR value .

Precautions For Use

 Explosion hazard. Do not use the oximeter in the presence of flammable

anesthetics mixture with air, oxygen, or hydrogen.

 When the oximeter is in use, there should not be any great power appliances

such as high voltage cables, X-ray machine, ultrasound equipment and
electrizer in use nearby.

 Keep the oximeter away from dust, vibration, corrosive substances, explosive

materials, high temperature and moisture.

 This oximeter does not have alarm function; please do not use this product in

the environment where alarm is required.

 The oximeter should be handled with care so as to avoid shocks and falls.
 When the oximeter is in use, it must be ensured that the batteries have

sufficient capacity; otherwise there might be such phenomena as starting-up
abnormalities or inaccurate measurement data, etc.

 Please don’t use pointed objects such as pen point or nails to press operation,

otherwise it might cause permanent damage to the surface of the keyboard.

 Don’t make any clinical judgments based only on the oximeter. The oximeter

is intended only as an adjunct in patient assessment. It must be used in
conjunction with clinical signs and symptoms, as well as doctor’s diagnoses.

 To ensure accurate performance and prevent device failure, do not expose the

oximeter to extreme moisture, such as direct exposure to rain. Such exposure
may cause inaccurate performance or device failure.

 Do not conduct SpO2 measurement on the finger smeared with nail polish,

otherwise this will lead to unreliable measurement results.

 The enclosure shall only be opened by the authorized person.
 In order to have more accurate measurements of SpO2 and PR, the oximeter

should be used in quiet and comfortable environment.

 Follow local ordinances and recycling instructions regarding disposal or

recycling of the device and device components, including batteries.

 Prolonged continuous monitoring may increase the risk of unexpected

changes in skin characteristics, such as irritation, reddening, blistering or
burns. Inspect the sensor site every two hours and move the sensor if the skin
quality changes.

 Pulse oximeter simulator can not be used to access the accuracy of the pulse

oximeter.

 This device complies with Part 15 of the FCC Rules. Operation is subject to

the following two conditions: (1) This device may not cause harmful
interference; (2) This device must accept any interference received, including
interference that may cause undesired operation.
The user is cautioned that changes or modifications not expressly approved
by the party responsible for compliance could void the user's authority to
operate the equipment
FCC STATEMENT:
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the
following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help.
FCC RADIATION EXPOSURE STATEMENT:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.

Intended Use

The Fingertip Pulse Oximeter is intended to measure functional arterial
oxygen saturation (SpO2) and pulse rate of adult and pediatric patients in
hospital, hospital type facilities, as well as in the home care environment.

The oximeter is not suitable to monitor patient continuously for long term.

Battery Installations

1. Press the button down on the back panel of oximeter and push

the battery cover horizontally along the arrow shown as below:

2. Install the batteries into battery cabin in correct polarities.

3. Close the battery cover.

Notes:
 Put or remove batteries in right order, or it may damage

the bracket.

 Battery polarities must be correctly installed. Otherwise, damage might

be caused to device.

 Please remove the battery if the oximeter will not be used for long time.

Press the button down

Software Download And Installation

1. Software download methods：
 Users who use the ISO system device can log in iphone App Store,

enter ”wearcare” and search for the of “SpO2 monitoring software” in the
searching results.

 Users who use the Android system device can log in the wearcare official

website: http://www.wearcare.cn for download.

2. Download SpO2 monitoring software, click installation button for free

installation.

Operation Instructions

1. Install two AAA batteries into battery cassette before closing its cover.

2. Open the receiving device (such as mobile phone, tablet PC etc.), then

turn on the Bluetooth.

3. Start the SpO2 monitoring software and connect automatically, the prompt

message” Complete device connection”. Till now, users can perform
SpO2 monitoring.

4. Nip the oximeter, then insert one finger into the rubber hole of the

oximeter before releasing the oximeter, and your nail must be upward.

5. Press the function button once on front panel.

6. Your finger and body do not tremble during measuring.

7. Read corresponding data on the display screen.

8. After turning on the oximeter, each time you press the

power switch, the display screen will change to another direction. There
are two display modes. If you long press the power switch, you can adjust
the brightness of screen from 1 to 5.

Maintenance

1. Use a soft cloth dampened with either a commercial, nonabrasive cleaner, or a

solution of 70% alcohol in water, softly wipe the surfaces of the oximeter.

2. The most commonly used hospital cleaning agent and non-corrosive

detergents can be used for cleaning the oximeter, but please be careful that
many types of detergents must be diluted before use; Please use them
according to the directions of the manufacturers of the detergents.

3. Avoid using alcohol-based, amido or acetone-based detergents .

4. The casing of the oximeter should be kept from the contamination of filth and

dirt, and it can be wiped with non-velvet soft cloth. When cleaning, don’t
spill the liquid onto the instrument. Ensure no liquid is allowed to enter the
inside of the oximeter.

5. It’s forbidden to use such grinding materials as wire brush or metal polishing

agent, for these materials may cause damage to the panels of the oximeter.

6. Please do not soak the oximeter in liquid.
