INNOAID. ORG BeRA Project ambulance for rural areas of India Carmen Bruno Marta Alice Fattorossi

Brief The challenge is the development of an ambulance that ensure the safety transport of patients from their households to the nearest clinic, day and night, in both wet and dry season. The project is going to be used in the Sunderbans region (West Bengal, India). INNOAID. ORG

Brief DESIGN REQUIREMENTS • Use of local transport • Man powered • Carry one patient and two attendants / relatives (3 people) • Protection from climate changes • Shock absorption • Repairable at any time and anywhere • Provide health service (Oxygen, saline fmuid, stretcher, shade, bucket) • Easy transportation of patient to and from the rural ambulance • Low cost (11,000 INR = 175 euro) Need higlighted by Doctor Amitrava, working in the health clinic founded by JGVK.

Concept Process Idea CONTRO-BRIEF AND PRIORITIES OPTIMIZE save the energy needed to move help the driver to the ambulance ride! The goal is to offer the opportunity for the second person to Selection of criteria in order of priorities ride, so that the ambulance can go faster, WITHOUT 1. patient care compromising the monitoring of the patient • visual inspection by the driver: always • space (on the stretcher ) for physical assistance 2. dimensions A B • width=max. 1m -road- • length=max. 3500 -current VR- 3. maneuverability • position of driving forces • visibility 4. effjciency • length and accessibility to the chain • perpendicular cycling INNOAID.

Concept Process Idea THE CHOICE This confjguration offers: C e D 850 B A • Visual inspection and a physical accessibility to the patient by BARELLA the driver in A when the parent is cycling in B o is sitting in C,D; 3000 • Possibility to sit next to the patient(2people: C, D); • The general dimensions are set in relation with the width of the street (not more then 1 m) and the length of the transport unit (not more then the standard V.R) • A shorter inferior chain provides less energy losses during the ride and it’s easly repairable if it came out from the “rails”; • The positions of the 2 riders (A, B) are on the central axis. Constraints: This provide a higher level of effjciency during pedalling. • stretcher extraction (long side) On the other side: • saline solution (1m from the patient) • cover • The visibility is limited due to the position of A and B in relation with the front cover structure.

Concept Process Idea EXISTING SOLUTIONS INNOAID. ORG

Concept Process Idea FIRST POSSIBLE POSITION OF THE PATIENT This confjguration prevents the extraction of the stretcher on the long side, due to the presence of wheels. In addition, the placement of the stretcher at a low rise (about 35 cm) is much more uncomfortable to extract. Cover Salin bag visibility 1000 stretcher 2000 extraction (short side) cover 400 o 700 mm saline solution 350 (1m) INNOAID. ORG

Concept Process Idea SECOND POSSIBLE POSITION OF THE PATIENT By choosing a smaller diameter for the front wheels (50 cm) is possible to place the support structure for the bed with an about 70 cm height, making the extraction from the long side possible and at the same time requiring less effort for those involved in the operation. We went on with this confjguration. Cover Salin bag visibility stretcher 2000 extraction (long side) cover o 500 mm o 700 mm saline solution (1m) INNOAID. ORG

Concept Process Idea SOLUTION General dimensions: 3000x850x2000 mm Stretcher dimensions: 1800x550 mm o 700 mm Sitting (C, D) dimensions: 1850x300 mm o 500 mm INNOAID. ORG

Concept Process Idea The mechanism to rotate the wheels connects the handlebars to the front wheels. The confjguration of this mechanism is still to defjne. We would like to talk with an engineer or with an expert to solve it. Handlebars Wheels INNOAID. ORG

Concept Process Idea Structure to hold the stretcher and the bench for the parents. 3 springs to adsorbe the vibrations INNOAID. ORG

Concept Process Idea The stretcher is made of a frame in wood and the inside part in 550 mm textile in a way to keep it lighter. The extraction take place from the left side by three handles. 1800 mm INNOAID. ORG

Concept Process Idea Parents, Patient and Driver INNOAID. ORG

Process Idea With this confjguration the patient is controlled even if the parents decide to cycle. INNOAID. ORG

Process Idea The ambulance can transport max 6 The covers of the two drivers can be people : 3 on the bench, 2 drivers and extract from the bottom of the cover. the patient. INNOAID. ORG

Process Idea Our main focus during the design process was the patient. We started the process trying to understand which would be the best position of the patient in relation with the driver. After the analysis of the different possible combination we found out that putting him in front of the driver was the best solution. The other our main concern was to use the third person to help to drive. We provided a second location to cycle behind the driver. According to the condition of the patient and the roads, the relative can decide if help to run or assist the patient. The bench allowed also to carry more than one person. We know that this is a concept and many things have to be added or changed. The mechanism to rotate the front wheels has to be designed. We know that this system could work but we stiil can’t understand how it works. Here are some video of other vehicle that use the same principle. http://www.youtube.com/watch?v=A3XUb5Rn948 http://www.youtube.com/watch?v=aTE6irdDSus We don’t know yet all the tecnhical stuff like the diameter of the tube, and we should make some structural calculation to know exaclty if the structure is stable. We miss some details like the light, the bag for the instruments and probably some mirrors to improve the visibility, but this are things that could be added in a second time. INNOAID. ORG

Process Idea During the process we realize that this one is not the only possibe solution that can be done, but we went straight on this because we think it answer at all the requirements of the brief. Of course, it still needs some improvement. We are aware that during the process we haven’t communicate so much with the danish guy, and this maybe would have helped a lot for the design of the ambulance and also for our knowledge about the indian lifestyle. We think they have done a great job in India. We realize the diffjculties of this project at half way, so it’s extraordi- nary that they built an ambulance there. We can imagine the amount of work they have done. All the informations they share in dropbox were really usefull for us and in general for the project. It’s very important to have a testimony directly from there and the people that will build or use the ambulance. We hope you can appreciate our contribute and we hope we can talk soon to have some feedback on our proposal and to go deeply on the argument. Thank you Carmen&Marta INNOAID. ORG
