关于客户
DePuy Spine Inc. 是强生医疗器械和诊断领域内一家快速发展的公司。它是骨科脊柱植入物的领先供应商,为因退行性疾病、畸形、创伤和运动相关损伤而患有脊柱疾病的患者提供解决方案。他们的主导产品之一是 CHARITÉ 人工椎间盘,这是美国推出的第一个设备,作为脊柱融合手术的替代方案,用于治疗退行性椎间盘疾病引起的腰痛。该公司致力于不断研究和开发,以提高其产品的性能和有效性。
挑战
DePuy Spine Inc. 是骨科脊柱植入物的领先供应商,一直致力于改善全椎间盘置换植入物的性能,特别是 CHARITÉ 人工椎间盘。这种三件式关节装置旨在消除疼痛并保持手术节段的运动,提供脊柱融合手术的替代方案。然而,了解植入物放置在椎间盘间隙内对小面负载的影响提出了重大挑战,已知超生理负载时会产生疼痛。涉及使用应变计和压力传感器进行尸体测试的传统研究既耗时又昂贵,而且往往没有结论。该公司需要一种更高效、更准确的方法来了解和优化 CHARITÉ 人造椎间盘的性能。
解决方案
DePuy Spine 研究人员利用强大的仿真软件 ANSYS Structural 来对 CHARITÉ 人造椎间盘的性能进行建模和分析。他们通过计算机断层扫描 (CT) 扫描实际骨骼结构获得了椎骨的轮廓几何形状,并使用 ANSYS 标准预处理功能对 CHARITÉ 的所有部分和周围组织进行了建模。该分析是在基于 Intel 的标准 IBM M Pro 桌面工作站上进行的。 ANSYS 表示非线性材料属性的能力在本研究中至关重要,其表面到表面的接触元素通过自动检测和调整不同的网格来辅助接触表示。这种创新方法使研究人员能够确定人工椎间盘的最佳位置,并了解其对脊柱生物力学的影响。

Case Study
Remote Temperature Monitoring of Perishable Goods Saves Money
RMONI was facing temperature monitoring challenges in a cold chain business. A cold chain must be established and maintained to ensure goods have been properly refrigerated during every step of the process, making temperature monitoring a critical business function. Manual registration practice can be very costly, labor intensive and prone to mistakes.

Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.

Driving Digital Transformations for Vitro Diagnostic Medical Devices
Diagnostic devices play a vital role in helping to improve healthcare delivery. In fact, an estimated 60 percent of the world’s medical decisions are made with support from in vitrodiagnostics (IVD) solutions, such as those provided by Roche Diagnostics, an industry leader. As the demand for medical diagnostic services grows rapidly in hospitals and clinics across China, so does the market for IVD solutions. In addition, the typically high cost of these diagnostic devices means that comprehensive post-sales services are needed. Wanteed to improve three portions of thr IVD:1. Remotely monitor and manage IVD devices as fixed assets.2. Optimizing device availability with predictive maintenance.3. Recommending the best IVD solution for a customer’s needs.
