DESCRIPTION (provided by applicant): Experts describe unmet needs in wheelchairs for individuals with high tone. They describe requirement for durability, light weight, adjustability, dynamic seating and modular components. These needs are especially critical for the wheelchair bound among the 100,000 children with cerebral palsy. This proposed children's wheelchair would demonstrate the NICHD mission to assist children in reaching "healthy and productive lives" free from disability. Having successfully demonstrated unmatched durability with a previous plastic wheelchair prototype, the new long-term proposal objective is a modular, lightweight plastic, durable and modular wheelchair with built-in dynamic seating. This project designs a prototype with consideration of synthetic material properties and function and reviews the design with assistive technology and clinical experts. It then fabricates prototype components and builds and tests the resulting prototype wheelchair. The anticipated properties include: a maximum weight of 22 pounds; significantly less than the tubular steel chairs presently available, dynamic seating that deflects with high tonal force and returns to its original dimensions, long-term durability as result of distribution of the high forces generated during spastic events, modularity with a removable seat that can be independently used. The chassis and seat will be designed based on data gathered from NICHD-supported design and build of the adult Merlexi Craft wheelchair. Experts at CATEA (Ga Tech) and Tampa Shriners Hospital will evaluate the design and suggest modifications. The modified designs will guide fabrication of prototype component parts from glass- reinforced and unfilled polypropylene sheet using CAM techniques. The components will be assembled into a prototype and tested for durability. The prototype will again be reviewed by CATEA and Tampa Shriners to define parameters for a Phase II program to produce, test, conduct human studies and gain FDA approval of the lightweight, durable children's chair. The need for a broader range of assistive devices that respond to the needs of a broad range of disabled individuals is a desirable public health goal. Further, another demonstration of the design capabilities and the durability and versatility of plastic vs. metal wheelchair devices can lead to consideration of new designs in synthetic materials throughout the medical device industry thus broadly benefiting medical care.

描述（由申请人提供）：专家描述了高语气人士对轮椅的未满足需求。它们描述了耐用性、轻量化、可调节性、动态座椅和模块化组件的要求。这些需求对于坐轮椅的 10 万名脑瘫儿童来说尤其重要。这款拟议的儿童轮椅将体现 NICHD 的使命，即帮助儿童摆脱残疾，实现“健康和富有成效的生活”。在成功展示了之前的塑料轮椅原型无与伦比的耐用性后，新的长期提案目标是打造一款模块化、轻质塑料、耐用且模块化的轮椅，并内置动态座椅。该项目设计了一个考虑合成材料特性和功能的原型，并与辅助技术和临床专家一起审查设计。然后，它制造原型组件并构建和测试最终的原型轮椅。预期的特性包括： 最大重量 22 磅；明显小于目前可用的管状钢椅，动态座椅可通过高音调力偏转并返回其原始尺寸，由于痉挛事件期间产生的高力的分布而具有长期耐用性，具有可拆卸座椅的模块化设计独立使用。底盘和座椅将根据 NICHD 支持的成人 Merlexi Craft 轮椅设计和制造收集的数据进行设计。 CATEA (Ga Tech) 和坦帕圣地兄弟会医院的专家将评估设计并提出修改建议。修改后的设计将指导使用 CAM 技术用玻璃增强和未填充的聚丙烯板材制造原型零部件。这些组件将被组装成原型并进行耐用性测试。该原型将再次由 CATEA 和 Tampa Shriners 进行审查，以确定第二阶段计划的参数，以生产、测试​​、进行人体研究，并获得 FDA 对这款轻质耐用儿童椅的批准。需要更广泛的辅助设备来满足广大残疾人的需求是一个理想的公共卫生目标。此外，塑料轮椅装置与金属轮椅装置的设计能力、耐用性和多功能性的另一次展示可以促使整个医疗器械行业考虑合成材料的新设计，从而广泛惠及医疗保健。
