Substances for the complex modus lubrication in artificial joints
Štol, Miroslav ; Musil, Jan ; Pražák, Josef
We have been studying some possibilities to fulfil the lubricationn demands in artificial joints. The interactions of gamma-globulin (GG) or polyvinylpyrrolidone (PVP) with sodium salt of carboxymethyl cellulose (NACMC) were followed by te rheological
Pulsatory flow under rotary pump used to failing heart support
Musil, Jan ; Převorovská, Světlana ; Leitermann, D. ; Pražák, Josef ; Maršík, František
The hydrodynamic resistance values increase in the mock-line circuit verified in some cases the concommitant phenomenon due to the continuous supporting device, i. e. complete destruction of the pulsatory wave form into the chaotic turbulent flow thro the supported system.
Circuit resistance modeling in failing heart rotary pump support
Musil, Jan ; Pražák, Josef ; Leitermann, D.
The stepwise resistance increase caused by the throttle valve usage in the mock-line circuit comprising the pulsating ventricle in failing heart modus and supported by rotary pump set up in parallel was studied. It appears thus important to regulate support system producing a continuous type of flow to such a regime not allowing the pulsating flow of the failing heart to disappear and preventing the mean systemic pressure value before substantial increase.
Numerical simulation of the cardiovascular hemodynamics during hemorrhaging
Převorovská, Světlana ; Maršík, František
The numerical model of the cardiovasculare system enables the simulation of the hemodinamic reaction activity as consequenceof the baroreflex response to various perturbations in the cilculatory system.The hemodynamic behaviour of the cardiovascular system in case of the circulatory failure caused by heemorrhagic shock is demonstrated.
