  11. Follow local disposal and recycling laws for the oximeter and its components, including the battery.
  12. Do not stare the light (the infrared is invisible) which emitted from the oximeter is harmful to the eyes.
  13. The oximeter is designed to measure the percentage of arterial oxygen saturation of functional hemoglobin. Any of the following conditions may reduce the performance of the oximeter.
  • Flicking or very bright light
  • Moisture in the oximeter
  • The individual weight less than 10kg
  • Week pulse quality(low perfusion)
  • Venous pulsations
  • Low hemoglobin
  • Cardiogreen and other intravascular dyes
  • Carboxyhemoglobin
  • Methemoglobin
  • Dysfunctional hemoglobin
  • Artificial nails or fingernail polish


2. The Basics

The pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2 concentration in the blood. It is an important bio-parameter for respiration. A number of diseases relating to respiratory system may cause the decrease of SpO2 in the blood, furthermore, some other causes such as the malfunction of human body’s self-adjustment, damages during surgery, and the injuries caused by some medical checkup would also lead to the difficulty of oxygen supply in human body. And the corresponding symptoms would appear as a consequence, such as vertigo, impotence, vomit etc. serious symptoms might bring danger to human’s life. Therefore, prompt information of patients Spo2 is of greats help for the doctor to discover the potential danger, and is of great importance in the clinical of medical field.


Principle of the oximeter is as follows: An experience formula of data process is established taking use of Lambert Beer Law according to Spectrum Absorption Characteristic of Reductive hemoglobin (Hb)and oxyhemoglobin(HbO2)in glow & near-infrared zones. Operation Principle of the device is: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning Recording Technology, so that two beams of different wavelength of lights 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.


Intended                                                                                                                              Use The Pulse Oximeter is portable, convenient, non-invasive devices, used for monitor arterial hemoglobin oxygen saturation (SPO2) and pulse rate. The personal application are adult patients (weight: > 30kg) and pediatric patients (weight: 20-30kg). We recommend index finger, middle finger and ring finger are suitable position for monitor. It’s intended for spot-checking or attended-care monitoring in Home Health Care and Medical Facility.

  • This pulse oximeter is intended for use in hospital,clinical institution, healthcare community.
  • The pulse oximeter is NOT designed for newborn and infant. For adults and children, it recommended that the finger thickness should between 8-25.4mm.


  • The probe is the hole in the middle of the equipment to which the finger insert.
  • The probe is the Applied Part of the equipment.


  • The pulse oximeter is small in volumes, light in weight and easy to carry.
  • Low in power consumption, 600 spot-checks on two AAA batteries.
  • One button and easy to operate.
  • There are three modes: power off, sleep and measure.
  • Automatically turning into sleep mode within 8 seconds after there is no signal.


  • Press the operating button to activate oximeter (measure mode) from sleep mode.
  • Power off after removing the batteries.

3. Battery Installation

A. Put the two AAA batteries into battery compartment in correct polarities.                              B. Push the battery cover horizontally along the arrow shown as right.


  • Battery polarities should be correctly installed, otherwise, damage may be caused to the equipment.
  • Please remove the batteries if the oximeter will be stored for more than 30 days.
  • Please remove the batteries if you want turn off the oximeter otherwise it is always in power state.
  • Battery may leak or explode if used or disposed off improperly


4. Operating Guide

Application Method

  • Remove the battery cover, and insert the two AAA batteries following polarity markings indicated inside of the battery compartment, then reposition the cover;
  • Hold the oximeter with the display facing toward you, slide your finger into the opening probe of the device, as shown below (Figure 4), until the fingertip touches the built-in stop guide. For best results, make sure the finger is centered within the finger guide.
  • Press the button to activate the oximeter from sleep mode, and then measurement interface will appear in 3 seconds.
