This document describes the design and implementation of a real-time vein imaging device. The goals were to create a portable, user-friendly, and cost-effective device to help doctors easily detect veins for procedures like drawing blood. The device uses near-infrared light to illuminate veins and a camera to display them. Prototypes were tested on subjects of various ages and skin types. The results showed promise for helping medical professionals, though limitations included lower visibility for some users. Future work aims to address limitations and make the device more accessible.

3. Motivation
• Doctors face difficulty detecting blood
arteries
• Visibility of the blood arteries results in
quicker & efficient blood withdrawal
• Helping doctors draw blood from infants and
elderly patients easily
• To make a cost effective vein detecting device
Goals

4. Background
Real-Time Vein Detector is a device with which we
aim to locate the veins in our arms easily for any
medical purpose for intravenous (IV) access
The veins can be seen and traced on the skin on
exposure of NIR making it easy to view and select
the right vein and not cause patients unnecessary pain
due to multiple punctures

21. Limitations
 Lower vein visibility for
• Obese people
• People with dark complexion
 No vein projection
• Laser
• HID Lamp projection
• Hybrid Projectors: A combination of LED and Lasers

22. Future works
 To get clearer image for obese and people with dark complexion
 To display on the device directly not via external display
 To project directly on skin
 Making the vein detector more user friendly
 Making accessible to all medical service providers, big or small
 To develop a system for advanced detection

23. Conclusion
Vein detection technique is not a new invention in the medical
imaging system but even then, it falls under the gap in technology
which gives us an alternative to the current medical practices. A
simple low-cost vein finding system has been designed which can be
made readily available to patients in high end hospitals as well as
primary health care centers.
