[Perfusion systems for hemodialysis].
According to generalized designs and technologies of devices used for extracorporeal blood transport in artificial purification and with due respect to their clinical usage, the modern perfusion systems, whose elements of hemodialysis units, can be classified by: a method of connecting them to the cardiovascular system of the patient, a type of perfusion pumps that are in use, and a technique regulating the extracorporeal perfusion velocity and the pressure at the exchanger inlet. The suggested classifications, structure models and results of research of the functional and technical parameters of perfusion systems showed their unified design principles irrespective of construction peculiarities, which can ensure the unified, reproductive, technological, simple and efficient application of the apparatuses now at the stage of creation.
Blood Pressure Determination↗
[Perfusion systems for hemodialysis].
On the basis of generalizing the principles of construction and of technical implementation of the extracorporeal blood-transport devices applied in artificial purification, which were described in the 1st part of the paper, mathematical models are suggested to calculate the stroke volume and the consumption of 2-roller perfusion pumps now used in hemodialysis. The above models were made use of to study the influence of the constructive and operational characteristics per consumption originated by the mentioned pumps.
Equipment Design↗
[Electric drive of alternate-flow inhalation generators used in apparatuses for artificial lung ventilation].
A method of selection of electric drive of alternate-flow inhalation generators used in apparatuses for mechanical lung ventilation (MLV) is suggested. This method is based on parametric equation for load compiled with due regard to required forms of inhalation and time characteristics of the beginning and end of inhalation. The structure and functions of the pulse astatic electric drive for commercially available MLV apparatuses are considered. This drive is consistent with the requirements for static accuracy of movement and positioning of electric drive of alternate-flow inhalation generators.
Electric Wiring↗
[A perfusion apparatus for extracorporeal purification of the blood].
Requirements for modern perfusion equipment intended for extracorporeal blood clearance are reviewed and possible trends in the improvement of the equipment in the BP-02 perfusion unit are defined. In that unit, one- or two-needle perfusion is maintained by a gearless drive, microprocessor control, concentrated data representation on a linear display in tabular form, and self-adjustment of the arterial and venous pressure control.
