Abstract

The purpose of this project is to develop a device that can serve to prevent hemorrhage after traumatic injury. There are approximately 205,000 instances of pelvic fracture per year. Most commonly these injuries result from car accidents. Assuming a ~1% market penetration, we would expect to treat about 2,000 of these. EMTs, physicians, and military personnel are the target users. Current PCCDs on the market have 5 main concerns that they do not address: access to the femoral artery, access to the gastrointestinal area, attachment for femur traction splints, interface with an autonomous vascular access device, and symmetrical pressure distribution. The MAIKO ring tackles all of these unmet needs, and even more. Our innovative design includes solutions to these problems, developed with the support of our House of Quality analysis, clinical and expert mentorship, and an iterative design process. In order to facilitate surgical access to the femoral artery and gastrointestinal area, the device features a tapered and smaller profile design leaving the femoral and gastrointestinal regions exposed without compromising the integrity of the ring. A design with integration for 3rd party treatment tools such as an autonomous vascular access device and femur traction splint has been addressed with the inclusion of attachable parts. Lastly, even pressure distribution has been achieved through a medial pressure application design on both greater trochanter regions of the patient. Controls have been considered and the device conforms to the FDA’s Quality System Regulation. Our design has been updated and improved using prototype testing on mannequins. After solidifying our design, we estimate that the unit cost of the device will be approximately $40.
