Reusable Adult Ear Clip SPO2 Sensor User Manual

Intended Use & Indications for Use

The reusable SpO2 sensors are indicated for continuous noninvasive monitoring of functional oxygen saturation of arterial hemoglobin(SpO2) and pulse rate(PR).
They are fully compatible replacement sensors intended for use with major brands of pulse oximeter. The SpO2 sensors are designed to match the specifications of the original equipment manufacturer, therefore ensure the appropriative sensor model number is selected for a particular pulse oximeter technology.

The models of reusable sensors suit for the following patients size:

  1. Adult (weight greater than 40 kg)

Principle of Operation

The sensors shall be connected with its corresponding monitor. Oxygenation of blood is measured by detecting the infrared and red light absorption characteristics of deoxygenated hemoglobin and oxygenated hemoglobin, which consists of a probe attached to the patient's finger. The sensor is connected to a data acquisition system which is used to calculate and display oxygen saturation levels and heart rate conditions.

Installation

  • Connect the SpO2 sensor to the adaptor cable of compatible oximeter.
  • Turn the oximeter on and verify proper operation.
  • Clip sensor unto fleshy part of the lobe as shown below. Do not place sensor on cartilage. Place the fixing mechanism on top of the ear.  












     

  • Apply the sensor on the patient.
  • Visually monitor the sensor site to ensure the integrity of the skin.

Precaution

  • The sensor and its cable must be cleaned before each patient
  • Place the sensor on the the ear lobe or auricle.
  • Do not use the sensor inside or near an MRI.
  • Avoid having intense light sources near the sensor
  • For long-term use, the measurement site must be checked and changed every 2-4 hours in order to guarantee the integrity of the patients skin.

    Equipment

    • Connect the sensor cable to the appropriate equipment (pulse oximeter).
    • Turn equipment on and check correct operation by consulting the monitor’s operation instructions.
    • To ensure proper monitor operations, connect and disconnect the sensor cable from the monitor cable. The correct, safe use of the sensor and its connecting cable requires systematic checks to be carried out at least once or more per month depending on the frequency of use, as well as disinfecting the cable.
    • Visual check (appearance of insulators, connector contact pins, etc.)
    • Verify the mechanical integrity of the connectors.
    Do not use and discard any sensor that appears to have any mechanical or electrical flaws.
