Observational study to understand and improve the human hand focussing of an Oesophageal Doppler probe.

“Deltex很高兴地宣布，它已经通过成功竞标2018年设计基金会第一轮比赛获得了Innovate UK的资金。Deltex是世界领先的食管多普勒超声血流动力学监测公司。使用该公司的TrueVue多普勒，被证明可以减少手术后患者遭受的并发症，并被NICE推荐。该系统还为医院节省了治疗并发症的费用，否则会导致住院时间延长。微创TrueVue技术使用插入患者食管（食物管）的超声探头。食道靠近病人胸部的主动脉，因此可以测量血流速度，就像警察的测速相机检查汽车的速度一样。在这种情况下，移动物体是血细胞。TrueVue系统测量血流速度和每次心跳的时间。然后，TrueVue计算一系列参数，这些参数对临床医生管理患者护理非常有用，从而最大限度地减少甚至预防术后并发症。临床医生通过感觉实现探头的聚焦，使用他们对心血管超声信号的了解进行导航。他们必须找到最佳插入深度并旋转探头以找到正确的信号质量。Deltex将使用赠款资助一项研究，以了解个人用户如何插入和聚焦超声波束。所获得的数据将有助于Deltex开发探头材料和包装系统的改进，以提高探头的可重复性。该项目将通过改进易用性而使临床医生和患者受益。Deltex预计，这一结果将增加已经证明有效的医疗设备的使用范围。"

"Deltex are pleased to announce that it has gained Innovate UK funding through a successful bid to the Design foundations round 1 2018 competition. Deltex is the world leader in Oesophageal Doppler ultrasound for haemodynamic monitoring. Use of the company's TrueVue Doppler, is proven to reduce the complications suffered by patients after surgery and is recommended by NICE. The system also saves hospitals the costs of treating complications that would otherwise result in increased lengths of stay. The minimally invasive TrueVue technology uses an ultrasound probe inserted into the patient's oesophagus (food pipe). The oesophagus lies close to the aorta in the patient's chest and so blood flow velocity can be measured much like a police speed camera checks a car's speed. In this case the moving objects are blood cells. The TrueVue system measures blood flow velocity and the timing of each heartbeat. TrueVue then calculates a range of parameters useful to clinicians in managing patient care and so minimising or even preventing post-operative complications. Clinician's achieve focus of the probe by feel, navigating using their knowledge of cardiovascular ultrasound signals. They have to find the optimum insertion depth and rotate the probe to find the correct signal quality.Deltex will use the grant monies to fund a study to understand how individual users insert and focus the ultrasound beam. The data obtained will help Deltex develop improvements in the probe's materials and packaging system to advance the probes handleability.The project will benefit clinicians and patients by leading to ease of use improvements. Deltex expects that the outcome will increase the range of uses of a medical device with already proven efficacy."
