Wireless Surgical Neuromonitoring Device

该项目的目标是设计和开发一种遥测刺激装置，可以在实际手术之前，期间和之后对患者进行连续的神经监测。外科神经监测提供关于特定神经结构功能的信息。这些信息被用来确认正确的神经结构被操纵或作为潜在的神经损伤的警报，由于目前的手术策略。几项研究表明，当进行神经监测时，患者受伤的数量显著减少。不幸的是，手术引起的压力或肿胀可能在手术结束后20分钟甚至更长时间内造成神经元损伤。然而，使用目前的神经监测装置，在实际手术前后与患者保持联系是不切实际的。该项目将开发一种刺激装置，该装置将连接并由克利夫兰医疗设备公司在其他SBIR项目下开发的无线患者监测器指导。一个单独的站被用来监测和记录信号。该装置将允许患者在手术中、手术中和手术后的每一次移动中都被连续监测，而无需移动接收单元。对于长距离，例如进入ICU，系统将自动将传输的数据传输到新位置的接收单元。该设备的开发将显著提高患者的安全性。首先，通过使术前和术后监测成为现实，可以在发生永久性神经损伤之前检测到延迟手术引起的损伤。其次，如果在转院过程中发生了损伤，对患者的持续监测将有助于确定已经发生的损伤，提供目前无法获得的信息。拟议的商业应用：除了用于手术室，该设备还可以用于昏迷患者，以确定其神经活动的变化。另一个与医学相关的用途是物理和职业治疗师使用的治疗性刺激。该系统还可用于各种市场，从工作场所的特殊培训研究到虚拟现实游戏控制器和反馈。

The goal of this project is to design and develop a telemetric stimulation device that can perform continuous neuromonitoring of a patient before, during and after the actual surgery. Surgical neuromonitoring provides information about the functionality of particular neural structures. This information is used to either confirm that the proper neural structure is being manipulated or as an alert of potential neural damage due to the present surgical strategy. Several studies have shown a dramatic reduction in the number of patient injures when neuromonitoring was performed. Unfortunately, surgically induced pressure or swelling may produce neuronal damage 20 minutes, or even longer, after the end of the surgery. Using the present neuromonitoring set-ups, however, it is not practical to stay connected to the patient before or after the actual surgery. This program will develop a stimulation device that will connect to and be directed by wireless patient monitors being developed under other SBIR programs by Cleveland Medical Devices. A separate station is used to monitor and record the signals. This device will allow the patient to be continuously monitored throughout each move into, during, and after surgery without moving the receiving unit. For long distances, such as going into the ICU, the system will automatically transfer the transmitted data to a receiving unit in the new location. The development of this device will significantly enhance patient safety. First, by making pre- and post-operative monitoring a reality, delayed surgically induced injuries can be detected before permanent neurological damage occurs. Second, if an injury occurs during a transfer, continuous monitoring of the patient will help identify that an injury has occurred, providing information that is not currently available. PROPOSED COMMERCIAL APPLICATIONS: In addition to being used in the surgery room, the device can also be used with people in coma to determine changes in their neural activity. Another medical related use is for therapeutic stimulation used by both physical and occupational therapists. The system can also be used for markets as diverse as special training studies in the workplace to virtual reality game controller and feedback.
