Glow and Infrared-ray

Receipt Tube

instrument is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording

Technology~

so

that two beams

of

different wavelengthoflights can be focused onto human nail tip through perspective clamp finger-type sensor. Then measured signal
can be obtained by a photosensitive element, information acquired through which will be shown on screen through treatment in electronic circuits and
microprocessor.

7.4 Press the switch buttononce on front panel.

3.2

Caution

1.

The finger shouldbe placed properly (see the attachedillustrationofthis manual ,Figure 7), orelse it may cause inaccurate measurement.

2. The

SpOz

sensor andphotoelectric receiving tube should be arrangedin a way with the subject's arteriolein a position there between.

3.

The SpOz sensor shouldnot be used ata location or limb tied with arterial canal orblood pressure cuffor receiving intravenous injection.

4.

Make sure the opticalpathisfree from any optical obstacles like rubberizedfabric.

5.

Excessive ambient light mayaffect the measuring result. It includes fluorescent

lamp~

dual ruby

light~

infrared heater, directsunlightand etc.

6.

Strenuous actionofthe subject orextreme electrosurgical interference may also affectthe accuracy.

7.

User can not use enamel or othermakeup.

3.3 Clinical Restrictions

1.

As the measure is taken on the basisofarteriole pulse, substantial pulsating blood flowofsubject is required. For a subject with weak pulse due to
shock, low ambientlbody temperature, major bleeding, oruse

of

vascular contracting drug, the

SpOz

waveform (PLETH) will decrease. In this case,

the measurement will be moresensitive to interference.

2. For those with a substantial amount

of

staining dilution drug (such as methylene blue, indigo green and acid indigo blue), or carbon monoxide

hemoglobin (COHb), or methionine (Me+Hb) or thiosalicylic hemoglobin, and some with icterus problem, the

SpOz determination by this monitor

may be inaccurate.

3.

The drugs like dopamine, procaine, prilocaine, lidocaineand butacaine may also be amajor factor blamed forseriouserrorofSpOz measure.

4. As the SpOz value serves as a reference value for judgement

of

anemic anoxia and toxic

anoxia~

some users with serious anemia may also report

good SpOz measurement.

Instructions to User

recommended tobeused

under

this circumstance.

The pulse oxygen saturation is the percentage

of

HbOz in the total Hb in the blood, so-called theOzconcentration in the blood. It is an important

bio-parameter

for the respiration. For the purposeofmeasuring the

SpOz

more easily and accurately, our company developed the Pulse Oximeter. At the
same time, the device canmeasure the pulse rate simultaneously.
The Pulse Oximeter features in smallvolume, low powerconsumption, convenient operation and being portable. It is only necessary for user to put one

of

his fmgers into a fingertip photoelectric sensorfor diagnosis, and a display screenwill directly show measured valueofHemoglobin Saturation.

2.1 Features
