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.

7.4 Adjustment range of lower limit alarming value of PR
(1)The sensor used in this equipment has a wavelength of red light: 660 nm, infrared light: 905 nm. These
light waves cannot directly illuminate the animal's eyes to avoid injury. When a treatment method similar
to photodynamic therapy is used during the measurement, the wavelength may be interfered to affect the
measurement.
(2)Periodically inspect the main components and accessories of the oximeter to confirm that there are no
obvious damages that may affect the safety and monitoring performance of animal. It is recommended to
check the product before each use. If the oximeter has obvious damage, stop using the product.
(3)when monitoring the tested animals for a long time, the position of the Spo2 sensor attached should be
checked every 2 hours, and the proper movement should be carried out when the skin changes. The
same measuring point should be measured continuously for up to 4 hours. Some tested animals may
need to be examined more frequently, such as those with perfusion disorders or skin sensitivity. Because
prolonged monitoring may increase unpredictable skin changes, such as allergies, redness, blistering or
compression necrosis.
(4)If there is an emergency to turn off the equipment, remove the probe from the sensor to stop the test,
unplug all the accessories in the equipmen and turn off.
(5)Please carefully check the equipment before using this product to confirm that it can be used normally.
(6)The sensor of this oximeter should not be used in the probe or other parts of the arterial catheter, blood
pressure cuff or intravenous injection.
(7)Make sure that the light source comes from the interior of the transparent silica gel. In addition, the light
source will affect the measurement results, including fluorescent lamps, red light source ,infrared water
heaters, direct sunlight and so on.
(8)Frequent activity of the subject or interference from external radio can affect the accuracy of the test.
(9)Only use the sensor specified in this manual and follow the instructions for use. Observe all warnings
and precautions.
(10)High frequency electrosurgical equipment and defibrillators can affect the use of the equipment.
(11)Use the equipment facing the operator and within 1 meter to view the measurement parameters.
8.1 Precautions
Warning:
If different alarming line values are used for the same or similar equipment in any single
area, there may be dangerous. For example, intensive care unit, heart operating room
and so on. Please set different alarming limits according to the condition of each tested
animal, and ensure its safety and effectiveness.
