While tracing veins in patients, there is a difficulty in locating the veins—especially in children, darker skinned and obese people which leads to unnecessary multiple needle pricks that causes pain and injury.

The vein tracer has been designed as a simple light-weight device that humanises a simple technology (NIR Spectroscopy), helping medical practitioners easily identify the veins during vein-puncture procedures, thereby reducing patients trauma.

Features

 ■ The vein detector is convenient, light weight

At the Photonics Laboratory in IIT Bombay, we are developing various photonic devices based on different spectroscopic techniques. They are tailored for various opto-electronic and sensing applications in the agricultural, healthcare and environmental sector.

Motivation    

 ■ A need for a healthcare monitoring system with fast detection response and reduced device footprint which is non-destructive for the sample, and also immune to external electromagnetic interference

Novelty
 

Mountainous land is widely distributed throughout the world and the soils in such area are subjected to many construction projects. The long term durability and fitness of the projects depend upon the soundness of the engineering behaviour of the soil. Due to the inferior geotechnical properties, sometimes mountainous soil poses serious threats on the projects during and/or after the construction. To improve their properties, lime can be utilised as it is cost-effective and easily available additive.

A helmet is an essential safety device but, lugging around a bulky helmet is so inconvenient that many two wheeler riders and their pillions would chose to go without one—even though this may be a fatal choice. While rules have come into place for enforcing helmet usage, there have been no noticeable design interventions for improving the Indian two-wheeler driver and pillions helmet experience. This is in spite of many improvements available in materials and technologies over the years.

As tradition, all of us visit temples for worship, but we never appreciate the beauty and efforts taken in building these lovely artifacts. Lighting that can enhance heritage temples and forts by night – is currently done in a fairly insensitive manner. Nails are driven into century old stone walls, irreparably damaging the sculptures, murals and inscriptions inside the temples. The

The Vaishno Devi Palki has been redesigned for improving the conditions in which Palkhi bearers make a livelihood. The existing heavy Palkhi which is 65 kg rests upon their shoulders causing injury and long term muscle damage in the Palkhi bearers.

Our team has designed a new Palkhi in stainless steel for the Shree Mata Vaishno Devi Shrine Board. This has a longer life and nil maintenance issues compared to the previous palkhi.
