Method of Application
Before using the product, medical staff should be familiar with how to correctly locate in order to get the best detection effect. In the process of use, it is recommended that the medical staff take touch and visual observation information for reference, combined with the projected image results to determine the actual location of veins. Please try to keep the observed of skin smooth and tight, give priority to choose areas of the organization with less scars, spots or hair.
Start The Instrument
Press and release the power button of the panel, then the instrument starts.
After the instrument starts up, power indicator lights up. According to the power quantity, the light shows two colors: white, blue. White represents high power, low blue stands for low power.
Please make sure that the power indicator is normal and power is full while the instrument works. Power indicator displaying blue indicates the instrument needs to be recharged in time. When the instrument is charging, charging indicator is flashing white light. If it is fully charged, charging indicator puts out.
Repeater Operation
Distance measurement: Pull the antenna out to maximum; make the antenna perpendicular to the surface of the skin and the antenna head contact the surface of the skin. You can observe instrument square image projected onto the surface of the skin. The grain of the image is corresponding with subcutaneous vein grain. Medical staff choose the appropriate target vein to complete the venipuncture.
Imaging mode switch: Insert the needle into the hole of projection window, press imaging mode switch button, image can be switched to blue-white, red-green and red-white imaging mode.
Image brightness adjustment: Touch image brightness adjustment button to adjust image brightness." " means brightness enhancement, " " means brightness reduction.
Sleep: The instrument starts sleep mode when touch sleep button. The image is off. Meanwhile, the instrument saves electricity. If you touch the sleep button again, the image restores.
Shut down
After using, press the power button, the instrument is turned off and power indicator is extinguished.
Suggestions for use
Clinical use: Two methods for clinical use are recommended. The first method is that medical staff begin venipuncture directly while using the instrument .The second one is to draw lines towards along the projection image of targeted veins by a medical skin marker. It is convenient for venipuncture after shutdown.
Sunlight or indicator light illume: While you are using the instrument, please do not make the measured surface of skin towards to the sun. Otherwise the vein image is incomplete. It is necessary to adjust the indoor illumination which can help medical staff to examine the vein display better.
