[Medical-technological equipment of nonphysician monitoring of health status].

Extrahospital monitoring of the body's status is an effective method for health promotion of man and the general population. The paper presents medical engineering rationale for the software of health monitoring under different conditions, identifies three base-line configurations of these complexes: for use in health institutions: for that in the institutions lacking permanent medical staff; for individual and familial use.

[The protective signalization of human vital functions: methodology, concept, devices].

The paper describes a basically new approach to solving the most pressing sociomedical approach, i.e. timely rendering a medical aid when acute vital dysfunctions suddenly occur in real daily life. A new concept of medical instrument making for human life and health protection has been developed on the basis of the theory of functional systems which discloses the universal mechanisms of self-regulation of the body's function. Its practical application is the design and patent a number of original devices of the protective signalling system which may be classified as information microprocessor devices designed for daily individual continuous control and notification of the first objective signs of physiological dysfunctions.

[Medical engineering technologies of diagnosis and correction of higher mental functions in children and adolescents].

This is an introductory article for this issue of the journal prepared on the basis of the proceedings of the Scientific-and-Practical Conference on Problems in Instrumental Evaluation of Higher Mental Functions and Dysfunctions in Children and Adolescents by using computer-aided test systems (medical engineering technologies developed at the turn of millennia). The paper deals with the analysis of the themes of the conference, its composition, and issues examined.

[Medical engineering computer technologies of testing cognitive functions in children].

Studies of higher mental functions in children are shown to present great difficulties in many parameters. Analysis has provided a number of requirements for medical devices and complexes and principles of their construction. Based on these data, the authors have developed and put computer test systems into practice, their advantages being shown. The studies of cognitive functions in children by using computer test systems are dealt with.

[State of the art and outlook for promoting Russian-made hemodialysis equipment with regeneration of dialyzing solution].

Radical improvements in the physiological features and self-sufficiency of hemodialysis equipment, an essential reduction of the volume of dialyzate contacting with patient's body and elimination of dependence of the equipment operation on the availability of a water-supply network can be ensured by applying a regime of circulation of a relatively small volume (3-5 l) of dialyzate through the regenerating device. The regeneration unit must eliminate the organic products of dialysis from the dialyzate and stabilize the ionic composition of the purified dialyzate according to the preset parameters. Modern methods and technical means for regenerating the used dialyzate are discussed; a regeneration unit, which ensures an electrochemical oxidation (in the used dialyzate) of nitrogen-containing organic metabolites with a subsequent sorption-type additional purification of electrochemically-processed dialyzate, is offered. The regeneration unit is made up of an electrolyser, a sorption-type additional-purification device and a gas utilizer; it eliminates organic metabolites, phosphorus, calcium and potassium from the used dialyzate and stabilizes the pH solution.

[Monitoring in surgery and resuscitation: current state, problems, and trends].

General problems of medical monitoring are discussed using monitoring in anesthesiology and resuscitation as an example. The current state of this important problem of biomedical engineering and perspectives of its further development based on sophisticated medical methods of measurement of vitally important parameters of patient are analyzed. The main emphasis was placed on the problems of collaboration between physicians and engineers in the development of monitoring systems and optimal information support of physicians during the use of monitoring systems in surgery and resuscitation. Special attention was devoted to facilitation of working conditions of physician with due regard to patient safety. The problems of appearance of monitoring errors, their origin, and approaches to their minimization are also discussed.
