# Vein Finder
A reliable, easy-to-make and open source device!
In the healthcare field, nursing staff frequently encounter difficulties when inserting a peripheral intravenous catheter (PIVC) into patients. Various factors can make it challenging to establish IV access, such as age, weight, hydration status, and even skin tone of the extremities. Often, a single puncture is unsuccessful, causing patient distress and increasing the risk of infection or trauma.
This is a device that, using LEDs, helps to contrast veins through the skin, making them visible, even those that are not deep, but also not the superficial ones that we observe with the naked eye. This is achieved thanks to hemoglobin, which absorbs the light that attempts to pass through the veins, making them visible.
## Calibration and Design Details:
Our design was mainly based on three different sources that will be linked below, all credit to the original authors. We focused our research on amount of LEDs and LED wavelength. We found numbers ranging from 8 to 30 LEDs. We decided to go with 20 LEDs for our design, it was the average. As for the wavelength we found that the colors that covered the widest range of skin tones were red and amber. The red LEDs had a dominant wavelength of 625 nm and the orange LEDs of 610 nm. We decided to go with 10 red and 10 amber LEDSs. We used PWM signals to give each color a 5 steps of brightness for better control.

## Testing and Trials:
The testing was done internally only. We asked different people from the office with different skin tones and checked if their veins were visible using the device.
## Risk and Usage Assessment:
The LEDs on the boards, as any other LED, can cause damage to the eye if they are looked at for prolonged periods of time. The device is a prototype and is not water or debris/dust proof.
