Fingertip Oximeter - Non-Medical - Blood Oxygen Saturation Measurement

For Sporting Or Aviation Only

This item has been removed 5 times in the past for being a prohibited listing (pharmaceuticals, medical devices), but has been relisted after being deemed not problematic each time. Please ensure the item is checked before removal.

This is a fingertip oximeter that easily measures blood oxygen saturation with your fingertip. This is not for medical use, but for sports or aviation (in-flight equipment), so the accuracy may be inferior compared to medical devices. Please use it as a reference value only.
*Medical devices are prohibited from sale on Mercari.

It is powered by 2 AAA batteries, which are sold separately. The product is new, but has been used once for a functional check, so please be aware of this. During the functional check, we confirmed that the power turns on, numbers are displayed, and the numbers are not abnormal (no significant difference compared to other devices). There have been reports that it does not work properly with manganese batteries, so please be sure to use alkaline dry batteries.

To use, simply press the white button and clip the oximeter onto your fingertip. After about 8 seconds, your blood oxygen saturation (%SpO2) and pulse rate (♥/min) will be displayed (the time to display may vary depending on measurement conditions). After measurement, the power will turn off automatically in about 5 seconds after removing your finger. The operation is simple, just press the button and clip it on your finger, so anyone can use it without confusion.

Additionally, errors may occur in the following situations:

1. When wearing nail polish, artificial nails, gel nails, etc., or if your fingers are dirty or your nails are discolored.
2. If the probe is not attached correctly.
3. If there is body movement during measurement.
4. If peripheral circulation is poor due to cold hands, low blood pressure, etc.
5. In cases of carbon monoxide poisoning or immediately after smoking.
6. In environments affected by ambient light (lighting, fluorescent lights, strong direct sunlight, etc.).

The product includes the main unit and a manual. As this is an overseas product, please understand that there may be some minor scratches or imperfections in precision.
