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

SCI的发病率在全球范围内每年从25万到50万不等，受影响的人数超过700万。目前，300 K美国 有SCI的人。SCI导致在发病率、死亡率、功能障碍、 地位、就业和生活质量。对于颈椎损伤的四肢瘫痪者，即使是基本的ADL也会严重受损。 暴露了个人学习ADL的辅助策略，如吃，喝，梳理，功能 洗澡、穿衣和洗澡。获得独立性是生活质量的关键因素，因为增加了独立的ADL 有助于提高自尊，信心和更好的心理健康。许多ADL中的一个关键特征是访问 饮用水、洗涤水和美容水。然而，水的控制和输送形式因素（开/关，温度， 力和角度以及流/喷射类型）对独特的ADL具有不同的要求。传统的雪茄非常 具有挑战性，如果不是不可能的话，具有高水平SCI和有限的控制自由度来调节和控制。 由Nasoni，LLC开发的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、直观的控制算法和互联的云数据 架构，以改善SCI中目标ADL的水可及性。智能水龙头设计提供水 通过传统的向下喷口或向上喷泉输送，允许所有人使用单个水龙头 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） 其可以基于个体的剩余控制自由度来校准。智能算法 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， 一个给定的任务。例如，水龙头将自动调整到温暖，喷雾，和更高的交付角度为脸 洗涤，而不是冷，流，和较低的交付角度饮用。最后，一个连接的云数据 架构和移动的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，其中技术水龙头基础，包括流量控制和 传感器已设计/原型化，控制算法已验证，综合系统已验证飞行员可用性。 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为 外形尺寸和传感器集成，以及系统级的技术验证。2)加强治水 具有扩展功能的算法，而新颖的诊断算法和连接的数字生态系统驱动 可用性和支持。3)将在SCI目标人群中测试增强型平台的临床可用性。四、 将设计过渡到正式的制造过程，以确保设计符合性能标准， 法规要求，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。

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.
