THE MEDICAL SOLUTION PROVIDERBringing Innovation to Life |
|
Medical SolutionsFor over 27 years, Analog Devices Products' mission has been to provide solutions that add value to their customers' systems. When you start the design of your next medical product, Analog Devices wants to be the one you go to for a value-added solution. The Medical Solutions Guide discusses 21 types of medical equipment, and provides an overview, block diagram, and technical discussions. It lists the Analog Devices products that will bring the most value to each type of equipment. Below you will find a brief overview and interactive block diagram for five of the solutions. For the full story on of Analog Devices’ medical solutions, please view the Medical Solution Guide. Blood Glucose MetersBlood glucose meters and other home medical devices today are small, portable, and easy to use. The mark of a good meter is one that the patient will use regularly and that returns accurate and precise results. Over the past few years the trend with blood glucose meters has been to maximize patient comfort and convenience by reducing the volume of the blood sample required. The blood sample size is now small enough that alternate-site testing is possible. This eliminates the need to obtain blood from the fingers and greatly reduces the pain associated with daily testing. Accurate and precise results have been increased by using better test strips, electronics, and advanced measurement algorithms. Other conveniences include speedy results, edge fill strips, and illuminated test strip ports, to name just a few.

Ultrasound ImagingBy transmitting acoustic energy into the body and receiving and processing the returning reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information. Historically, the large number of high-performance phased-array transmitters and receivers required to implement these imaging systems resulted in large and expensive cart-based implementations. Recently, advances in integration have allowed system designers to migrate to smaller, lower cost, and more portable imaging solutions with performance approaching these larger systems. The challenge moving forward is to continue to drive the integration of these solutions, while increasing their performance and diagnostic capabilities.

Suggested Components
Pulse OximeterPulse oximeters noninvasively measure or continuously monitor oxygen saturation in arterial blood to ensure that there is sufficient oxygenation. Typical applications include people with respiratory problems who are under anesthesia, neonates, and critically ill patients. In a pulse oximetry system, a clip with optical electronics is usually attached to a finger, toe, or ear so that light can be transmitted through the skin from one side of the clip and received on the other side with a photodiode. Good arterial blood flow is required to measure oxygen saturation. Most applications use transmissive optical techniques, but there are some applications that use reflective techniques.

Suggested ComponentsInfusion PumpComputer-controlled infusion pumps represent a vast improvement in accuracy and safety over old-fashioned drip-chamber and roller-clamp systems. Modern infusion pumps provide a precisely controlled rate of fluid delivery to the patient through an intravenous (IV) line. They also include state-of-the-art safety features to ensure that any single failure of any significance is detected and reported immediately. There are two classes of infusion pumps: large-volume pumps (LVPs) and small-volume pumps (SVPs, or syringe pumps). In an LVP, the fluids are usually contained in an IV bag or bottle, and the pump manipulates a special section of tubing between it and the patient's IV site. Some infusion pumps have the ability to control up to four IV lines to the patient, although one- and two-line versions are the most common. Closely related to the LVP is the syringe pump. This device presses the plunger of a large syringe at a precisely controlled rate. The infusion rate of these syringe pumps is generally orders of magnitude lower than that of LVPs. Aside from the pumping mechanism, almost all other aspects of syringe pumps are similar to LVPs.

Suggested Components
ECG (Electrocardiograph)An electrocardiogram (ECG or EKG) is the measurement and graphic representation, with respect to time, of the electrical signals associated with the heart muscles. Applications of an ECG range from monitoring heart rate to the diagnosis of specific heart conditions. The basics of ECG measurement are the same for all applications, but the details and requirements for electrical components vary greatly. Electrocardiographs, or ECG devices, range from portable handheld units costing less than $200, to units that cost over $5,000 and are the size of facsimile machines. An ECG may even be embedded in a separate piece of equipment, such as a patient monitor or an automatic external defibrillator (AED).
