Point of Care Tracheostomy Tube Patency Monitor using an Ultrasonic Flow Sensor

 描述(由申请人提供)：Koronis Biomedical Technologies Corporation(KBT)建议开发一种创新的带警报的护理点气管切开气流监测系统，目标是儿科患者。在美国，气管切开置管是一种越来越常见的儿科做法。虽然这是一个拯救生命的程序，但它增加了我们的医疗系统的巨大成本，并继续充满并发症。气管切开术的两个严重风险是气管切开管移位和粘液堵塞。当孩子将设备放在适当的位置时，这些情况随时可能发生。年幼的儿童特别容易患上 缺氧，无法清理输卵管，也无法向照顾者传达痛苦。目前，没有足够的技术在患者缺氧和病情恶化之前监测这些事件，当使用气管切开管的儿童没有使用机械呼吸机及其相关的监测器和警报时。这种情况会影响到那些只在部分时间进行机械呼吸、接受CPAP或BiPAP辅助呼吸的儿童，或者正在自发呼吸的儿童。这一提议的装置将适用于气管切开管的标准末端，并将提供早期警告，提醒护理人员注意管子的阻塞或移位。该设备的目的是触发更早的照顾者干预，以防止儿童患者受到与缺氧相关的伤害。

 DESCRIPTION (provided by applicant): Koronis Biomedical Technologies Corporation (KBT) proposes to develop an innovative point of care tracheostomy airflow monitoring system with alarm, targeting pediatric patients. Tracheostomy tube placement is an increasingly common pediatric practice in the United States. While this is a lifesaving procedure, it adds significant cost to our healthcare system and continues to be fraught with complications. Two serious risks of tracheostomy are dislodgement and mucous plugging of the tracheostomy tube. These can occur at any time while the child has the device in place. Small children are at particular risk of hypoxia, and are unable to clear their tubes, or communicate distress to caregivers. At present, there are no sufficient technologies to monitor for these events prior to patient hypoxia and deterioration when a child with a tracheostomy tube is not using a mechanical ventilator with its associated monitors and alarms. This condition affects children who are mechanically ventilated only part of the time, receive breathing assistance by CPAP or BiPAP, or are breathing spontaneously. This proposal device will adapt to the standardized end of a tracheostomy tube and will provide early warning to alert caregivers to an obstruction or dislodgement of the tube. The goal of this device is to trigger earlier caregiver intervention to prevent hypoxia related injury to the pediatric patient.
