Problematika efektivního koeficientu statického tření na plochách kloubních náhrad
Franta, L. ; Pražák, Josef
Study of static and kinetic friction with lubrication HA, HA with vitamin E, CMC, Bovine serum, solution physiological and without lubrication at friction surfaces of joint replacement made from steel-UHMWPE. Measurements were done at inflexional tribometr.
Realistic simulation of wear tribology in joint replacement of human joints
Franta, L. ; Pražák, Josef
Testing is a significant contribution in the field of joints replacement realistic simulation. Realistic simulation of tribologic conditions is realized by simulator KKK typ ELO 98001 in joint replacement of human joints. Simulators burdening and kinematic characteristics are according to key requirements.
Realistic simulations joint replacement human joint
Franta, L. ; Pražák, Josef
Any artificial testing of joint replacement is considered as contribution significant to research in the field of joint replacements. The fundamental parameter, which influeces a length of survival, is an effective coefficient of friction, especially in low mutual speed of friction surfaces of joint replacements.
Frictional heating of total joint replacements
Němeček, R. ; Pražák, Josef
Total joint replacements heat up due to friction more then natural joints. The paper contains review of frictional heating of total joint replacements in vitro and in vivo. Thermal effects during friciton of femoral (vitalium) and tibial (UHMWPE) components of the knee joint replacement with the physiological solution, HA, bovine serum lubrication depending on the load, frequence and damage of UHMWPE are studied.
Thermal aspects of friction in joint replacements
Němeček, R. ; Pražák, Josef
Thermal effects during friction of femoral (vitalium) and tibial (UHMWPE) components of the knee joint replacement with the physiological solution, HA, bovine serum lubrication depending on the load, frequence and damage of UHMWPE are studied. There is the possibility of monitoring the state of joint replacements in vivo.
Experimentální testování vyvinutého prvku systémového odporu krevního řečiště pro simulační linky kardiovaskulárního systému
Chlup, Hynek ; Pražák, Josef ; Kovičková, S.
The element simulating the body tissue resistance changesrepresents the dominant part in the cardiovascular modeling circuit set-ups. Alternative element of simulation line system cardiovascular circuit was development and sham resistance of the bloodstream. Model of body resistance system approximate to physiological its disposition and parameters. Requisite pressure and resistance was created multiple embranchment flow liquids. General flow cross-section magnify and speed liquids in digressive, thereby with approximate of real.
