If you understand the grey line of difference between urgency and emergency then the concept of an Ambulance Rickshaw by Benoit Angibaud will make more sense to you. It befits the need of developing nations, where crime and health concerns has no limits. Hence, you may little realize what crisis situation you have to face in next few hours. The Ambulance Rickshaw is capable of driving the injured or aged to the hospital within no time. Considering the condition of rural Africa transport, this form of ambulance can really be a savior. It features a blind that offers sunshade to the patient residing inside and a stretcher that allows an easy holding of a patient.

What next? Driver steps in, hops in front, gets to wheeling, and here they push towards a medical center. Surely, it is much cheaper form of commuting than standard ambulances. But yes, for performance it needs few potential hands that can develop this structure.

It’s presence would surely make a difference between life and death.

The Roll-A-Bout SW-500 (featured above) is the Roll-A-Bout Corporation’s flagship product designed and developed for people tormented with a lower leg wound. Now they can shun their crutches or even wheelchair and ride on this model. The SW-500 support up to 500 lbs and is touted as company’s first creation with steering functionality.
It is suggestible that the ‘hopping’ movement offered via Roll-A-Bout is beneficial than the ‘swinging’ motion of the crutches. But eyebrows are raised regarding the comfort left of this model.

I am assuming it to be better than wheelchair as it keeps the rest of the body in active state. The standard SW-500 model is retailed at $599, while an ATV or ‘off-road’ edition costs $739! And the fancy wire basket inserted on the face of the model demands an extra $15.
