The COX801VB is a hand-held pulse oximeter that uses non-invasive measurement of
transmission.
A monitor that measures SpO2, PR, PI, pulse wave intensity, and pulse wave using a pulse
oximetry sensor.
The COX801VB features continuous measurement on a 5-inch TFT screen. The COX801VB
provides two display states for both horizontal and vertical screens.
1.2 Product Description
Since the non-invasive pulse and blood oxygen saturation measurement are based on
the pulsation of the small arteries, the tester's blood should ensure a steady flow. When
a subject is weakly perfused due to vibration, low temperature environment, major
bleeding, or medication using systolic blood vessels, the waveform displayed by the
device will shrink and, therefore, sensitively interfere with the measurement of the
product.
9 kinds of heavily diluted colored drugs, such as: blue, indigo, green and acidic indigo
methylene, or carboxyhemoglobin, or methionine, or hemosin and some jaundice,
Measuring pulse oximetry with this device can lead to erroneous results.
Related drugs such as dopamine, procaine, prilocaine, lidocaine and budacaine tend to
be factors that affect serious errors in pulse oximetry.
Shock, anemia, hypothermia or the application of vasoconstrictor drugs cause arterial
blood flow to drop to an unmeasurable level;
Intravascular stains such as phthalocyanine or methylene blue may affect the
measurement.
Do not fix the sensor of this product in a location where the animal has tissue damage.
Not suitable for use in animals allergic to TPU, ABS, silicone plastic.
The pulse oximetry sensor can detect or continuously detect non-invasive SpO2, PR, PI,
etc. of the animal.
This product can be used in hospitals, homes, medical clinics, mobile medical aid
stations, etc.

4 Working principle
COX801VB can continuously measure arterial oxygen saturation without non-invasive. Usually
a sensor is placed in the test site and connected to the COX801VB by cable.
The measurement principle of this product is spectrophotometry.
(1)Differences in the absorption of visible light and infrared light by oxyhemoglobin,
deoxyhemoglobin and plasma.(Such as figure 3)
(2)The amount of arterial blood varies with the pulse, so the amount of light absorbed by
different numbers of arterial blood also changes.
The COX801VB uses a 2-wavelength sensor to distinguish between oxyhemoglobin,
deoxygenated hemoglobin and plasma in the blood. The light of the light-emitting diode of the
COX801VB using the two-wavelength sensor is transmitted to the photodiode through the
measurement site, and the electrical signal obtained by the photodiode through the light
absorption change in the blood pulsation cycle is transmitted to the COX801VB, and the
COX801VB calculates the pulse rate according to the electrical signal returned by the sensor,
Pulse oximetry, perfusion index, plethysmographic wave, bar graph, etc.(Such as figure 4)
3.1 SpO2
The COX801VB continuously measures pulse rate continuously.
3.2 PR

5 Operation and use
(1) Ensure that this equipment is kept away from dust, vibration, corrosive substances, explosive
materials, high temperature and high humidity.
(2) After the COX801VB gets wet, stop using it.
(3) Do not use this product immediately if it is transferred from a low temperature environment to
a high temperature environment.

(5) Do not immerse the device in a liquid. If you need to clean the product, wipe the surface of the
device with a soft cloth dampened with disinfectant. Please do not spray any liquid directly on this
device.
(6) When the oximeter is turned on, if the interface is not displayed or the information that should
be displayed is incomplete, stop using the oximeter. Next, please contact a qualified service
person, the agent of the local US company or directly contact the company's service department.
