项目摘要

DESCRIPTION (provided by applicant): The goal of this proposal is to develop a STAT palm-sized blood counter for monitoring complete blood counts (CBC) with 3-part differential during emergencies. Changes in blood counts can reflect acutely worsening medical conditions. For instance, a rapidly rising white blood cell count may occur during infections or a leukemic blast crises. Hematocrit values may rapidly decline in traumas, gastrointestinal bleeds, and post- procedure recoveries. Platelet values may drop significantly during chemotherapy and idiopathic thrombocytopenic purpura. During these situations, close and frequent monitoring of a patient's blood counts is a must to deliver the best care and treatment, whether it be blood transfusions, platelet transfusions, or drug administrations. These clinical scenarios reflect a significant market need. In 2007, $2.7 billion of hematology tests were performed. Of these, an estimated 25-35% of these tests were STAT tests, which are ideally performed at the point-of-care. The proposed blood counter samples a fingerstick of blood from the patient and analyzes it in real-time at the patient's side for point-of-emergency clinical decision making. This is in contrast to today's measurement technologies, which require a benchtop instrument and a trained technician. The central hypothesis for this Phase II SBIR effort is this: microfluidic technology can be utilized to develop an integrated palm-sized blood counter that requires only a pinprick of blood. The proposed 24-month Phase II effort leverages our Phase I accomplishments in microfluidics, sensitive detection, and precision measurements to develop a prototype handheld emergency blood sensor. Advances in detection and microfluidics are required to develop such a device. Specific Aim 1 will utilize our microfluidics technology to assess serial cell dilution ad red cell lysis. Specific Aim 2 will be utilized to develop an integrated optical and electrical impedance detection system required for measurement of a wide range of cell parameters. Specific Aim 3 will be utilized to develop a handheld, breadboard prototype of our STAT blood counter and validate its performance against a gold-standard blood counter across a set of clinical samples. Success in Phase II will lead to a Phase III effort which will include detailed product engineering for a commercial STAT blood counter product, tests for FDA 510(k) approval, and commercialization. The resulting product can be utilized in a wide- range of settings including ambulances, inpatient rooms, operating rooms, medical offices, and resource- starved settings.
描述(由申请人提供):本提案的目标是开发一种手掌大小的 STAT 血液计数器,用于在紧急情况下监测全血细胞计数 (CBC),并进行三部分分类。血细胞计数的变化可以反映出医疗状况的急剧恶化。例如,在感染或白血病急变期间,白细胞计数可能会迅速上升。在创伤、胃肠道出血和术后恢复过程中,血细胞比容值可能会迅速下降。化疗和特发性血小板减少性紫癜期间血小板值可能显着下降。在这些情况下,必须密切频繁地监测患者的血细胞计数,以提供最好的护理和治疗,无论是输血、输血小板还是给药。这些临床场景反映了巨大的市场需求。 2007 年,进行了价值 27 亿美元的血液学检测。其中,估计 25-35% 的测试是 STAT 测试,最好在护理点进行。所提出的血液计数器从患者的指尖采血进行采样,并在患者身边实时分析,以便做出紧急临床决策。这与当今的测量技术形成鲜明对比,当今的测量技术需要台式仪器和经过培训的技术人员。 II 期 SBIR 工作的中心假设是:微流体技术可用于开发一种集成的手掌大小的血液计数器,只需针刺血液即可。拟议的 24 个月第二阶段工作利用我们在微流体、灵敏检测和精密测量方面取得的第一阶段成就来开发手持式紧急血液传感器原型。开发这种设备需要检测和微流体技术的进步。具体目标 1 将利用我们的微流体技术来评估连续细胞稀释和红细胞裂解。具体目标 2 将用于开发测量各种细胞参数所需的集成光学和电阻抗检测系统。 Specific Aim 3 将用于开发 STAT 血液计数器的手持式面包板原型,并在一组临床样本中对照金标准血液计数器验证其性能。第二阶段的成功将导致第三阶段的努力,其中包括商业 STAT 血液计数器产品的详细产品设计、 FDA 510(k) 批准的测试和商业化。由此产生的产品可用于多种环境,包括救护车、住院室、手术室、医疗办公室和资源匮乏的环境。
