Blood Analysers

Blood analysis processes are streamlined to ensure that patients receive the most effective lab-quality results within minutes with improved system efficiency

They perform a broad menu of the most commonly performed diagnostic tests, including cardiac markers, blood gases, chemistries and electrolytes, lactate, coagulation, and hematology. Blood analysers primarily include the motor electronics for controlling the centrifuge. Then there are optical systems, LEDs, various (optical) sensors, pipette devices and lab-on-a-chip elements as well as chips for power management and control of input/output units. While large blood analysers often contain a complete embedded control board, in smaller devices, a microprocessor or a microcontroller often provides the required computing power.

Identification

In medical technology, it is important that all the elements of a system work together properly

With an integrated RFID tag, it is possible for the individual elements to effectively identify themselves electronically. In this way, manufacturers ensure that only the appropriate accessory, the right probe or the special single-use element is connected to the device. Manufacturers can therefore ensure that only original accessories from their company are used and no imitation products are used that might cause hygiene or liability problems. If the device only operates using original accessories protected by RFID technology, the manufacturer has also taken due care in this logistical aspect. The range of possible applications for object identification via RFID is huge, since RFID can be used to identify blood supplies just as easily as chemical components, which are mixed together to repair teeth. There are even RFID tags, which work at -150 °C, so that virus samples, cryo samples, etc., can be identified via RFID, whereas labels often fall off at these extreme temperatures. If the tag is incorporated in the plastic of a blood bag, for example, clear identification is possible after it has been thawed.

Microscopes

Microscopes require LED illumination (LED + control) and a CMOS image sensor

Image processors or DSPs evaluate the signals from the sensor and convert them into a digital image. A microcontroller, which controls the entire microscope, forwards the video signal via common interfaces to the display unit - for example, a PC. Some microscopes also have a motorised XY table, which then requires the control and power electronics with the corresponding sensors. In addition, as in almost all systems there is a circuit responsible for the power management.
