ADI intros AFE chips for ECG systems
Analog Devices, Inc. (ADI) has introduced the first product in a series of fully integrated analog front-end (AFE) chips that enable electrocardiogram (ECG) systems to achieve monitor- and diagnostic-quality performance. The device also incorporates pacemaker pulse detection and respiration measurements, which are critical features of high-performance ECG systems.
The ADAS1000 ECG AFE simplifies the design of a five-
electrode ECG systemby significantly reducing the signal chain bill ofmaterials fromup to 50 components down to the ADAS1000 single chip plus a few discrete components, said ADI. The device can be configured to optimize noise performance, power, or data rate,making it suitable for home, ambulatory, and clinical ECG systems.
The ADAS1000 targets a variety of ECG systems, including
diagnostic electro-cardiographs, bedside patient monitoring systems, Holter monitors, and cardiac defibrillators.
The ADAS1000, housed in a 10 x 10-mm 64-lead LQFP, is
priced at $28 each in quantities of 1,000. ADI also plans to offer the ADAS1000 in an 8 x 8-mm 56-lead LFCSP package. Samples and evaluation boards are available.
www.analog.com ST to produce iChip processor
STMicroelectronics will produce the iChip microprocessor for the LifeNexus Personal Health Card. LifeNexus is the developer of the iChip and Personal Health Card, which is the first multi-purpose electronic health card using the
embedded iChip for securelymaintaining an individual's personal health record, with a payment card option on the same card.
The LifeNexus Personal Health Card was designed specifically to secure
andmaintain an individual's Personal Health Record (PHR) on a wallet- sized card. The patented iChip, or Individually Controlled Health Information Platform, uses a "mobile server" technology embedded on a chip card, which is both encrypted and password-protected, providing a highly secure environment to store comprehensive health information for individuals and their familymembers, said ST.
LifeNexus said the individual's information is not stored on aWeb-
based server, eliminating consumer concerns about storing sensitive data on an unrelated third-partyWeb server, while supporting the adoption of electronicmedical records by their health care providers.
www.st.com Bud offers enclosures formedical equipment
Bud Industries, Inc. offers both customized and off-the-shelf solutions for medical equipment OEMs. These include a range of electronic enclosures including cabinet racks, NEMA boxes, plastic enclosures, server racks, and other rack equipment to meet the special requirements of medical electronics applications.
These lines include enclosuresmade of stainless
steel, plastic, aluminum, and powder-coatedmetals resistant tomost common chemicals used by the medical industry,which can be supplied aswaterproof enclosures suitable for sanitarywashdowns.
One example is Bud's NBD Series plastic NEMA box,
which features a sealed hinged lid,making it a waterproof enclosure. Another control box supplied by
Bud is used onmotorizedwheelchairs. This heavy-duty die cast AN Series aluminumenclosure has custom- drilled holes for the controlwiring and iswatertight.
The SNB Series stainless steel enclosures are
used to house the electronics inmany other medical applications. Constructed of 16-gauge 304 stainless steel, these boxes are well-suited for applications where sturdy construction, security, and a seal againstmoisture are required. The hinged covers clamp to their base with a keyed quarter-turn latch that requires a non-traditional key for added security. Theymeet the watertight specification of a NEMA 4X enclosure.

LEMO has redesigned the traditional plastic push-pull connectors, originally introduced to themedicalmarket in 1964, with the introduction of the REDEL XP connector. The new connector is designed using a plasticmaterial that is friendly to sterilization processes, and comes with an ergonomic grip thatmakes itmuch easier for surgeons andmedical staff tomate and align, said Lemo.
The connector's latching systemis now
embedded in the shell for increased impact resistance with a high contact density,
whichmakes it well-suited formedical or measurement applications, ranging from catheters to surgical instruments.
The REDEL XP line is available with four
different keyways to prevent inadvertent cross connects ormisconnects by the user. The outer shell standard color is gray with an option of white or black. Backnuts and receptacle front nuts are available in seven colors for application identification. Contact configurations range from4 to 22 contacts and can be crimp or solder type.
