[Medical equipment at the Leipzig Fall Fair, 1978]. / Meditsinskaia tekhnika na Leiptsigskoi osennei iarmarke 1978 g.

This is an attempt to reveal the main directions and trends in the medical technique progress, as evidenced by the most interesting exhibits at the 1978 Autumn Leipzig Fair. Advantages of the functional-block designing method were noted, seen in the instruments made for clinical diagnostic laboratories. Promising features are emphasized, intrinsic for units intended for reconstructive X-ray tomography, autoanalysers for studying blood, enzymes and substrates, as well as for ultrasonic diagnostic devices. The latter provide a combination of A and B-mode echography, or the M-type scanning with Doppler ultrasonic pulse investigation. Such a combination allows to fix on the echogram the precise position of the structure being investigated by the Doppler approach.

Thermal treatment substantially influences the resistance of calibres used in mollification (vacuum calibrating) of glass cylinders for medical syringes, the highest resistance of calibres made of the XH32T alloy and the 12X18H10T steel being achieved through their preliminary annealing in the argon atmosphere. The quality of manufactured syringes is affected also by wrong calibres shape and, formostly, by their out-of-roundness, whose degree in individual cases reaches 2--3 micrometer.

[Medical equipment at the Leipzig Fall Fair of 1977]. / Meditsinskaia tekhnika na Leiptsigskoi osennei iarmarke 1977 g.

An analysis of the most interesting exponents of the Leipzig autumn fair of 1977 served as a groundwork for an attempt to outline the major orientation and trends in the development of the biomedical engineering. The advantages of the functional units method of designing are taken notice of on an example of some groups of devices manufactured both in the countries members of the Council for Economic Mutual Assistance and in western countries. Emphasis is placed on the good prospects offered by medical devices for ultrasonic location of the heart with the type M scanning, of the X-ray units intended for solving concrete diagnostic objectives within a narrow branch of medicine (apparatus for mammography, for use in urology, etc). Particular attention is paid to the medical equipment utilizing the elements of computer technique, in the form of built-in units and also in that of complex setups in which small computers ensure the most effective realization of the diagnosis and treatment.
