The IV-Buddy

当液体通过输液管进入体内时，应监测输液管，以避免空气栓塞或形成可堵塞管路的血凝块。这通常是由医院护士和救护车护理人员盯着滴注器来完成的。对于动脉中的导管（在X射线下可见的细管）干预，其中连续给予液体对于防止血液在导管内凝结很重要，市场上没有适合监测流量的产品。血流中断，即使只有一分钟，也可能导致血栓，从而导致严重残疾或死亡。移动的卒中单元慈善机构的医生和护理人员与Nvention的创始人一起，确定了对一种简单设备的需求，该设备可用于救护车和医院的大脑和心脏手术。我们的发明，IV-巴迪，自动发出警报，如果流到体内的滴线停止。IV-Buddy具有新颖的传感器技术，可提高输液期间患者的安全性。有了IV-Buddy，宝贵的护理时间不需要花在反复检查滴注器上。输液泵也有可能使用，但它们价格昂贵，操作繁琐，不易获得，也不适用于导管介入。我们易于使用的IV-Buddy将提高患者的安全性，特别是在输液泵稀缺的低资源环境中。IV-Buddy还有其他应用。陆军军医很高兴地了解到这种新工具，可以在疏散士兵或大规模伤亡事件中挽救生命。其他应用包括家庭输液和透析、献血或医院和救护车中的患者运输。有了IV-Buddy，输液泵过于昂贵的贫穷国家的液体监测成为可能。IV-Buddy的创新之处在于：\* 市场上没有这样的设备，\* 它通过自动提醒临床医生出现问题来降低患者的风险，\* 它使用简单，\* 它的成本低，使人们普遍负担得起。这笔赠款将资助技术设计，以纳入用户在看到我们早期的原型后要求的产品扩展。我们还将获得有关获得监管机构批准所需的临床试验（在救护车和导管实验室）的信息和计划。在此资助期间开发的IV-Buddy的改进版本将作为其新功能评估的一部分进行原型制作，并在模拟环境中进行测试，以评估其安全性。

Whenever fluid is given into the body via a dripline, the dripline should be monitored to avoid air embolism or formation of blood clots that can block the tubing. This is conventionally done by hospital nurses and ambulance paramedics peering at the drip chambers. For catheter (thin tubes visible under X-rays) interventions in arteries, where continuous administration of fluids is important to keep the blood from clotting within the catheters, there is nothing suitable on the market to monitor flow. Interruption of flow, even for only a minute, can lead to blood clots that can result in severe disability or death.Doctors and paramedics of The Mobile Stroke Unit Charity, together with founders of Nvention, identified the need for a simple device that can be used on ambulances and in hospitals for operations in the brain and heart. Our invention, the IV-Buddy, automatically sounds an alarm if flow within a drip line into the body stops. The IV-Buddy has a novel sensor technology that leads to increased patient safety during infusions. With the IV-Buddy, valuable nursing time does not need to be spent repeatedly inspecting drip chambers.Infusion pumps could potentially be used, but they are expensive, cumbersome to handle, not readily available and not usable for catheter interventions. Our easy to use IV-Buddy will improve patient safety, especially in low-resource settings where infusion pumps are scarce.The IV-Buddy has other applications. Army medics were excited to learn of this new tool that saves lives while evacuating soldiers, or during mass casualty events. Other applications include home infusion and dialysis, blood donation or patient transport in hospitals and ambulances. With the IV-Buddy, fluid monitoring becomes possible in poorer countries where infusion pumps are too expensive.The IV-Buddy is innovative as:\* there is no such device on the market,\* it lowers the risk to patients by automatically alerting the clinician of a problem,\* it is simple to use,\* it can be low cost, making it widely affordable.This grant will fund technical design to incorporate product extensions requested by users after seeing our earlier prototype. We will also obtain information on and plan for the clinical trials (in the ambulance and catheter lab) needed to gain regulatory approval.The improved version of the IV-Buddy developed during this grant will be prototyped as part of the evaluation of its new features and tested in a simulated environment to evaluate its safety.
