[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.

[Supplying therapeutic equipment to tuberculosis departments and hospitals].

The paper provides evidence for that the development of new treatments of tuberculosis by using up-to-date technical means and their introduction into practice. It gives the data of the researches and developments made by the VNIIMP-VITA close joint stock company, which are both aimed at providing tuberculous units and hospitals with necessary therapeutical equipment, such as devices for pneumothorax, endoscopic studies, etc.

[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.

[Radionuclide methods of measuring mineral contents in the bone tissue].

Over the recent 10-15 years, osseous densitometers intended for measuring the content of minerals in osseous tissue have become very popular abroad. To record statistically significant changes in an osseous mineral, these devices should have reproducibility (variation rate) exceeding 2%. Mono- and biphoton densitometers may be distinguished by the type of the applied radionuclide. Biphoton densitometers are advantageous since they permit examining any part of the skeletal system of the patient or the whole body. Biphoton absorptiometry is based on measuring the transition of photons of two energies via the medium that largely consists of the two materials bone and soft tissue. The authors describe the results of examining parts of the peripheral skeleton with the aid a laboratory sample of a biphoton osseous densitometer for the peripheral skeleton.
