Numerous patients including infants and elderly people require multiple attempts for a successful intravenous (IV) catheter insertion. It is reportedthat on average 2.18 venipuncture attempts areneeded for a successful IV catheterization. The reason of increased number of attempts is due to numerous physiological differences of patients. The skin color, depth of veins due to fats present under skin, presence of hair on skin or scars contribute to the increased difficulty level of veins localization. The staffs in the field of medicine struggle in veins localization process that may result in some medical complications including veins rupture or skin bruise. In order to reduce the number of painful attempts in catheter insertion we propose a device which can be used to localize subcutaneous veins. Few devices are available but they are either bulky, inefficient and/or nonuser friendly. A wearable optical imaging device which is efficient, light weight and easy to use will add in the quality of medical care and will reduce the efforts and pain in IV catheterization process. In literature many researchers presented their work for subcutaneous veins localization by different methods. Near Infrared (NIR) imaging has gained most of the attention due to the unique properties of deep penetration in biological tissues, being low cost and having no side effects on patients due to its non-ionization property. The proposed work will focus on the design of a compact, low power, light weight and wearable device based on the principle of NIR imaging which will be used by medical personals for IV catheter insertion. The final objective of this project is to design an efficient, robust, cost effective, and portable device for subcutaneous veins localization.
