Venepuncture assistive devices (VAD) include ultrasonography, and devices that utilize infra-red or transillumination. These are expensive, not widely available, and have not been rigorously proven to be effective. This preliminary study using an ordinary pen-torch for transillumination showed promising results. 95% of patients with known difficult venous access required two or less attempts for successful cannulation. It costs 35 times cheaper compared to the cheapest VAD in the market. The concept is promising but the technique cumbersome.
