Access-H20: Sensor driven smart faucet to enable and empower independent drinking and grooming for individuals impacted by spinal cord injury

全球每年脊髓损伤的发病率在25万到50万之间，有700万人受到影响。目前&gt；30万美国 患有脊髓损伤的人。脊髓损伤在发病率、死亡率、功能性 地位、就业和生活质量。对于有颈椎损伤的四肢瘫痪患者，即使是基本的ADL也是严重的 妥协了。个人学习ADL的辅助策略，如吃、喝、打扮、功能 洗澡、穿衣、上厕所。获得独立性是生活质量的关键因素，因为添加独立的ADL 有助于增强自尊、自信和更好的心理健康。许多ADL中的一个关键功能是访问 用于饮用、洗涤和美容的水。然而，水的控制和输送形式因数(开/关、温度、 力和角度，以及流/喷雾类型)对唯一的ADL有不同的要求。传统的水龙头非常 具有挑战性，如果不是不可能的话，具有高水平的SCI和有限的控制自由度来调整和控制。 由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、自动流量调整、直观的控制算法以及联网的云数据 架构，以改善SCI中目标ADL的水可及性。智能水龙头设计可提供水 通过传统的向下喷嘴或向上喷泉输送，允许所有人使用一个水龙头 在一个家庭里。系统设计将集成传感器网络(接近、语音、摄像头和眼睛凝视传感器) 它可以根据个人剩余的控制自由度进行校准。智能算法 地图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 一项特定的任务。例如，水龙头将自动调节到温暖、喷射和更高的面部输送角度 洗涤，而不是冷饮、流水和较低的出水角度。最后，互联的云数据 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。 该项目将建立在成功的第一阶段，在该阶段，技术水龙头基础包括流量控制和 传感器设计/原型设计，控制算法验证，集成系统在飞行员可用性中验证。 第二阶段将以五个总体目标扩大这一基础。1)优化目前的水龙头设计将用于 外形尺寸和传感器集成，以及系统级别的技术验证。2)加强治水 具有扩展功能的算法，同时新的诊断算法和互联的数字生态系统驱动 可用性和支持。3)增强的平台将在脊髓损伤目标人群中进行临床可用性测试。4) 将设计过渡到正式的制造过程，以确保设计符合性能标准和 法规要求并生产用于测试的试生产原型5)进行家庭临床试验，以 展示Access H2O智能传感器水龙头的有效性。

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.
