concentration in the blood. It is an important bio-parameter for the respiration. Many of the
respiration disease will cause hypoxemia, even damage the patient’s life. As a result, monitoring the
SpO
2
is indispensable in the clinical rescuing. The traditional method to measure SpO
2
is to analyze
the sample of the patient’s blood to get the partial pressure of oxygen and calculate the SpO
2
by use
the blood-gas analyzer. This method is inconvenient and discontinuous. For the purpose of
measuring the SpO
2
more easily and accurately, our company developed the Fingertip Pulse
Oximeter. The device can measure the pulse rate simultaneously.
The Fingertip Pulse Oximeter is tiny, and with low power consumption, convenient to use and carry.
You just need to put the fingertip into the sensor of the device, the SpO
2
value will appear on the
screen immediately. In the clinical practice, the tolerance is smaller than ±2% in the range from 70%
to 100%.
2.1. Features
A.
The device can accurately measure SpO
2.
B.
The device will power off automatically if no signal is detected within 5 seconds.
C.
Two AAA size batteries are required for operating, and the continuous working time is 30
hours.
D.
When Low-Voltage Warning is shown on screen, the device maybe not operate normally.
E.
Light and portable, total weight with batteries is about 50g.
F.
Classification: Class II a,

2.2. Anticipative application
The Fingertip Pulse Oximeter can detect SpO
2
and pulse rate through patient’s finger, and indicate
the pulse intensity by the bar-display. This device is applicable for use in home, hospitals (ordinary
sickroom), oxygen bar, the community medical treatment, physical care in sports (you can use the
device before or after the sport, but it is not recommended to use it during the sport) and so on.
This device is not appropriate for the ceaseless monitoring of the patients.
