Guangdong Healthtree Medical Technology JKS50A Fingertip Pulse Oximeter
Owner’s Manual
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.

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 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 for sports or aviation use only.
-
The oximeter should be handled with care so as to avoid shocks and falls.
-
When the oximeter is in use, it must be ensured the batteries have sufficient capacity; otherwise there might be such phenomena as starting-up abnormalities or inaccurate measurement data, etc.
-
Please do not use such pointed objects as pen point or nails for pressing operation, otherwise it might cause permanent damage to the surface of the keyboard.
-
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.
-
Please do not open the enclosure. 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.
Intended Use
This product is intended for sports and aviation use only. It should not be used to diagnose or treat any medical condition.
Operation Instructions
- Install two AAA batteries into battery cassette before closing its cover.
- Nip the oximeter, then insert one of fingers into the rubber hole of the oximeter before releasing the oximeter, and your nail surface must be upward.
- Press the function button once on front panel.
- Your finger and body do not tremble during measuring.
- Read corresponding data in only one direction on the display screen.
Battery Installations
- Press the button down on the back panel of oximeter and push the battery cover horizontally along the arrow shown as below:
- Install the two AAA batteries into battery cabin in correct polarities.
- Close the battery cover.
Notes:
- Pay attention to the correct polarities terminals of the battery, which are marked with plus and minus signs. Do not install the battery in the direction of the spring.
- Please remove the battery if the oximeter will not be used for long time.
Maintenance
- Use a soft cloth dampened with either a commercial, nonabrasive cleaner, or a solution of 70% alcohol in water, lightly wipe the surfaces of the oximeter.
- 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.
- Avoid using alcohol-based, amido or acetone-based detergents
- 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, do not spill the liquid onto the instrument. Ensure no liquid is allowed to enter the inside of the oximeter.
- It is forbidden to use such grinding materials as wire brush or metal polishing agent, because these materials may cause damage to the panels of the oximeter.
- Please do not soak the oximeter in liquid.
- Under normal circumstances, it is unnecessary for the oximeter to have special maintenance, and cautions must be exercised on the following points during the use of the oximeter:
- Please use the oximeter in the environment according to the requirements of the performance criteria.
- Avoid contacts with organic solutions, dusts or corrosive gases.

Sensors specifications
Wavelength| Pulse oximetry sensors contain LEDs that emit red light at a
wavelength of approximately 660 nm and infrared light at a wavelength of
approximately 905 nm.
The total optical output power of the sensor LEDs is less than 15 mW.
This information may be useful to clinicians, such as those performing
photodynamic therapy.
Note: Sensor LED light emissions fall within Class 1 level, according to
IEC 60825-1:2001. No special safety precautions are required.

Solution
---|---|---
There is no response to the function button.| The button can not be pressed to
its position| Ensure that the button is fully depressed.
Battery capacities are low| The batteries may be missing, discharged, or
oriented incorrectly.
Replaced them with new ones.
The Pulse search time is too long| Perfusion may be too low| Change the
measuring site. Try another oximeter.
person movement| Interference due to person activity may be preventing the
oximeter from tracking the pulse. Keep the person still, if possible.
Electromagnetic interference may be preventing the oximeter from tracking the
pulse.| Remove the source of interference.
There may be interference due to ambient light, or the oximeter may be on an
extremity with a blood pressure cuff, arterial catheter, or intravascular
line.| Reposition oximeter, as necessary.
Display is dark-or-bright| Battery capacities are low.| Replace the batteries.
