U.S. Setting New Records
Power Saver for Wireless Medical Devices

Low power wireless connectivity is attainable in an array of medical devices with the advent of Bluetooth Core Specification 4.0. Technology features, including 5-10 year button cell battery life in low duty cycle applications, are outlined in Medical Electronics Design. Power consumption is minimized due to event-driven data acquisition/transfer architecture.

Hybrid Connectors simplify the user interface, speed device setup, and improve patient safety by eliminating misconnections.

Portable Diagnostics Depend on Solid Analog Design

Turbulence Modeling Tames Tight Turbines The process of getting patient vital signs data into a portable diagnostic tool is delicate in the extreme, as the signals, such as those from ECG leads, are extremely weak. Astute analog and mixed-signal design approaches are required every step of the way, right up to the conversion to digital form. This overview piece in Electronic Design outlines the challenges encountered in the design of a variety of portable diagnostic devices.

Small and Efficient Power Supply

Turbine Transformer Tips The compact size of this AC-DC power supply makes it ideal for use in home healthcare and portable medical systems. Considered the smallest 60 W unit available, the convection-cooled dynamo offers efficiencies of 87-89%. The 2 x 3 x 1.05 in. (50.8 x 76.2 x 26.7 mm) unit also meets international medical safety standards.

Time for a Blood Pressure Check

Bird and Bat Science A continuous blood pressure monitor in wristwatch form is the focus of a two-month clinical trial underway in Singapore. Arterial pulse waves measured at the wrist are converted into useful data by proprietary software and transmitted to a centralized station for analysis. Improved cardiovascular care is the goal of such remote, real-time monitoring.

Power to the Portable

Taming Transport Bottlenecks For portable diagnostic devices, power consumption when connected to an external power source, operating time when on batteries, and patient safety at all times depend on proper power design. Add in the increased computing power required and there is quite a power design challenge. A design piece in Medical Design Technology discusses the balancing act required to achieve a system that achieves the goals.

Hidden Spectrum

Ultra-capacitors Make Their Pitch Wireless connectivity at frequencies away from commonly used portions of the spectrum could be a boon to designers and manufacturers of portable medical devices. It turns out that there is just such a chunk of spectrum set aside by the FCC for “ultrawideband” radios operating at very low power output, an arrangement that is ideal for devices operating within a healthcare facility. The high-data-rate radios, for which there are internationally recognized standards, can operate over distances of three to thirteen meters.

Persistence Pays Off

Driving Drivetrain Reliability There is a third way – a messaging system for embedded systems different from either the better-known asynchronous or synchronous schemes. Although requiring a robust file system and a reliable storage medium, persistent publish/subscribe (PPS) messaging could be the answer for portable medical devices containing sensors, displays, input devices and an HMI. PPS has several advantages for this kind of system, including data retention after reboot.
