SCI incidence ranges from 250k-500k globally/year, with >7M people impacted. Currently >300k U.S. individuals live with SCI. SCI results in life-altering consequences in terms of morbidity, mortality, functional status, employment, and quality of life. For quadriplegics with cervical injuries, even basic ADLs are severely compromised. Individuals learn assistive strategies for ADLs such as eating, drinking, grooming, functional bathing, dressing, & toileting. Gaining independence is key factor for quality of life, as adding independent ADLs contributes to increased self-esteem, confidence, and better mental health. A key feature in many ADLs is access to water for drinking, washing, & grooming. However, control & delivery form factor of water (On/Off, temperature, force & angle, and stream/spray type) have different requirements for unique ADLs. Traditional faucets are very challenging, if not impossible, with high level SCI and limited control degrees of freedom to adjust and control. The Access-H2O smart faucet, being developed by Nasoni, LLC, will solve these market challenges by intelligent sensor integration, automated flow adjustment, intuitive control algorithms, & connected, cloud data architecture to improve water accessibility for targeted ADLs in SCI. The smart faucet design delivers water through either traditional downward spout or upward fountain delivery, allowing a single faucet to be used by all in a household. System design will integrate a sensor network (proximity, voice, camera, & eye gaze sensor) which can be calibrated based on an individual’s remaining control degrees of freedom. Intelligent algorithm mapping will allow users to activate and adjust the faucet through various flow and temperature parameters for a given task. For example, the faucet will automatically adjust to warm, spray, and higher delivery angle for face washing, as opposed to cold, stream, and lower delivery angle for drinking. Finally, a connected, cloud data architecture and mobile app will support calibration, usability, remote service, and clinical reporting. This project will build on successful Phase I, in which a technical faucet foundation including flow control & sensors were designed/prototyped, control algorithms verified, & integrated system validated in pilot usability. This Phase II will expand that foundation with five overall Aims. 1) Optimize the current faucet design will be for form factor and sensor integration, as well as technically verified at the system level. 2) Enhance water control algorithms with expanded features, while novel diagnostic algorithms & connected digital ecosystem drive usability & support. 3) The enhanced platform will be tested for in clinic usability in the SCI target population. 4) Transition the design to formal manufacturing process to ensure that design meets performance standards and regulatory requirements and to produce pre-production prototypes for testing 5) Conduct in-home clinical trial to demonstrate effectiveness of Access H2O smart sensor faucet.

全球每年 SCI 发病率在 25 万至 50 万之间，目前美国有超过 700 万人受到影响。 患有 SCI 的患者会在发病率、死亡率、功能方面产生改变生活的后果。 对于颈椎损伤导致四肢瘫痪的人来说，即使是基本的日常生活活动也很严重。 个人学习日常生活活动的辅助策略，例如饮食、仪容仪表、功能性的。 获得独立的洗澡、穿衣和上厕所是生活质量的关键因素，因为增加了独立的日常生活活动。 有助于增强自尊、自信和改善心理健康。许多 ADL 的一个关键特征是获得机会。 然而，水的控制和输送形式因素（开/关、温度、 力和角度以及水流/喷雾类型）对独特的 ADL 有不同的要求。 具有高水平的 SCI 和有限的控制自由度来调整和控制，即使不是不可能，也是具有挑战性的。 Nasoni, LLC 开发的 Access-H2O 智能水龙头将通过以下方式解决这些市场挑战： 智能传感器集成、自动流量调节、直观的控制算法以及连接的云数据 改善 SCI 中目标 ADL 的用水可达性的架构 智能水龙头设计提供水。 通过传统的向下喷嘴或向上喷泉输送，允许所有人使用单个水龙头 系统设计将集成传感器网络（接近、语音、摄像头和眼睛注视传感器） 可以根据个人剩余的控制自由度进行校准。 映射将允许用户通过各种流量和温度参数来激活和调节水龙头 例如，水龙头会自动调整为温暖、喷雾和更高的面部出水角度。 清洗，而不是冷、流和较低的饮用角度最后，一个连接的云数据。 架构和移动应用程序将支持校准、可用性、远程服务和临床报告。 该项目将建立在第一阶段成功的基础上，其中包括流量控制和 设计/原型化了传感器，验证了控制算法，并在飞行员可用性中验证了集成系统。 第二阶段将通过五个总体目标来扩展该基础： 1) 优化当前的水龙头设计。 外形尺寸和传感器集成，以及系统级别的技术验证 2) 增强水控制。 具有扩展功能的算法，同时新颖的诊断算法和互联数字生态系统驱动 3) 增强的平台将在 SCI 目标人群中进行临床可用性测试。 将设计过渡到正式的制造过程，以确保设计满足性能标准和 监管要求并生产用于测试的预生产原型 5) 进行家庭临床试验 展示 Access H2O 智能感应水龙头的有效性。
