The Challenge

This system integrator focuses on providing centralized gas pipeline monitoring systems for hospitals. The service they provide makes it possible for hospitals to reduce both maintenance and labor costs. Since hospitals may not have an existing network suitable for this type of system, GPRS communication provides an easy and ready-to-use solution for remote, distributed monitoring systems System Requirements - GPRS communication - Seamless connection with SCADA software - Simple, front-end control capability - Expandable I/O channels - Combine AI, DI, and DO channels

The Solution

Moxa's innovative cellular RTU controller solutions overcome several issues that confound traditional GPRS RTU solutions. Issue 1: The GPRS network can not communicate with devices that are behind firewalls. Moxa's Solution: Active OPC Server, which is available free of charge, can handle all remote GPRS RTU controller connections--even those located behind firewalls. Issue 2: SCADA software is unable to access GPRS RTU devices connected via private IP addresses. Moxa's Solution: Moxa's free Active OPC Server makes it easy for SCADA software to connect to remote GPRS RTU devices. Issue 3: Limited RTU options available on the GPRS RTU device Moxa's Solution: Moxa's GPRS RTU products can expand their I/O ports. Each Moxa W5300 GPRS device can be extended with up to three ioLogik E1200 I/O devices. Up to 66 I/O channels are supported. Moreover, Moxa offers GPRS RTU in a variety of different combinations. DI, DO, AI, AO, Relay, RTC, and TC are all supported. Moxa's GPRS RTU devices come with software tools in addition to the hardware. These tools help customers quickly build remote monitoring and alarm systems with Moxa's GPRS RTU solutions. Project Applied: - Free Moxa Active OPC Server - I/O expansion via ioLogik E1200 series - Click&Go control logic

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.

IoT Based Health Monitoring System

The primary challenge was to monitor the progress of the plans adopted by the patients. In most cases, the patient will start with a plan and give up in the middle. It is important to motivate them to continue through the plan.

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.

Harnessing real-time data to give a holistic picture of patient health

Every day, vast quantities of data are collected about patients as they pass through health service organizations—from operational data such as treatment history and medications to physiological data captured by medical devices. The insights hidden within this treasure trove of data can be used to support more personalized treatments, more accurate diagnosis and more advanced preparative care. But since the information is generated faster than most organizations can consume it, unlocking the power of this big data can be a struggle. This type of predictive approach not only improves patient care—it also helps to reduce costs, because in the healthcare industry, prevention is almost always more cost-effective than treatment. However, collecting, analyzing and presenting these data-streams in a way that clinicians can easily understand can pose a significant technical challenge.
