ARTIFICIAL HEART VENTRICLE Russian patent published in 1995 - IPC

FIELD: medical equipment. SUBSTANCE: heart ventricle has case 1 provided with branch pipe 2, cap 3 provided with branch pipe 4, elastic partition 5 which divides cavity of case 1 to chamber 6 for blood and pneumatic chamber 7, branch pipe 8 and valve 9; valve 10 is disposed inside branch pipe 9. L-shaped branch pipe 2 is formed by dome-shaped and tubular members 11 and 12 correspondingly. Longitudinal axes of the members are located at different planes. Hole 15 is made in wall of member 11 in align to its axis 14. Average part of branch pipe 9 is disposed inside hole 15 without any space; end 16 of branch pipe 9 is disposed inside member 11; longitudinal axes 14 and 17 coincide. Valve 10 is made in form of a ball, valve 8 is made in form of annular elastic diaphragm 18 which has internal side to be connected to end 16. External side is made for interaction with base 19 of member 11. Artificial heart ventricle creates twisted flux of blood that helps to eliminate stagnant areas in the ventricle being hazard because of forming of clots of blood. As longitudinal axes of member 11 of branch pipe 9 and case 1 coincide, number of turbulent areas is reduced, so traumatism of formed blood members is reduced either. EFFECT: reduced forming of clots of blood in branch pipes. 5 dwg
