Automated external defibrillator made of PC/ABS

1322

The emergence of automated external defibrillator (AED) devices has helped to save thousands of lives across the world. They are light, portable and can be taken to the patient on-site, rather than having to risk damage and death getting back to a heavy, hospital-based and mains-powered crash cart. Certain models can even be used by untrained staff as part of normal first-aid duties. But they must be safe and reliable. Wisconsin-based Cardiac Science Corporation (CSC), a global manufacturer of external defibrillation, diagnostic devices and monitoring systems, has chosen a polycarbonate/acrylonitrile butadiene styrene (PC/ABS) blend resin from Bayer MaterialScience LLC for its next-generation Powerheart G5 AED line.

Rugged and reliable

CSC’s decision to choose Bayer’s Bayblend FR3010 PC/ABS blend resin for the device was based on the material’s impact performance, overall strength and UL flame rating. Many of CSC’s emergency services and military customers use AEDs in demanding conditions, which requires ruggedisation but without sacrificing lifesaving features. Bayer worked with the company to help select the specific material. Dickten Masch Plastics injection moulds the Bayer material to form the Powerheart G5 device’s battery case and housing, which contains all the electronics and acts as a protective cover for the internal components. The outer shell that passed all of CSC’s drop and durability test, while meeting its quality protocols and product development timelines. Its corporate colour scheme was matched using pre-coloured plastics created with Bayer’s LEDA compounded colour technology.

The battery case and housing is injection moulded and contains all the electronics and acts as a protective cover for the internal components.

Cardiac Science is part of Opto Circuits (India). It develops, manufactures and markets a range of advanced diagnostic and therapeutic cardiology devices and systems. As well as AEDs, it makes electrocardiograph devices (ECG), cardiac stress treadmills and systems, PC-based diagnostic workstations, Holter monitoring systems, hospital defibrillators, vital signs monitors, cardiac rehabilitation telemetry systems, and cardiology data management systems (informatics) that connect with hospital information system (HIS), electronic medical record (EMR), and other information systems. It is the successor to the cardiac businesses that established the Burdick, HeartCentrix, Powerheart, and Quinton brands, and has operations in North America, Europe and Asia.

The growing uses of Makrolon

The AED was on display at Bayer’s stand at MD&M West, earlier in 2013, which was also the setting for the unveiling of Makrolon Rx2440 medical-grade PCB. Bayer says that the new material possesses optimal flow properties and achieves faster recovery time in colour shift from sterilisation to part usage. It is claimed to be suitable for a variety of applications, including IV access, respiratory, surgical and renal care. Cannuflow’s EntreVu EX, a clear arthroscopic access cannula body designed to help with fluid management during arthroscopic surgery, uses Makrolon Rx1452. PCB was selected by the manufacturer because of its mouldability, biocompatibility and clarity, which helps the surgeon see surgical knots more easily.

Q-Flo connector is said to offer improved safety and convenience for healthcare workers administering cytotoxic drugs to patients.

Another medical application utilising Bayer’s Makrolon resin is also used in Infusion Innovations’ (I3) Q-Flo valve connector. The manufacturer asserts that the Q-Flo connector offers improved safety and convenience for healthcare workers administering cytotoxic drugs to patients. The application required a reliable material meeting US Food and Drug Administration (FDA) requirements, as well as a proven safety and functional profile.
