Title:
ARTIFICIAL DIALYTIC PUMP
Document Type and Number:
Japanese Patent JP3193076
Kind Code:
B2
Abstract:

PURPOSE: To dispense with the sealing of a housing without bringing about the lowering of the life of a bearing in an artificial dialytic pump.
CONSTITUTION: Since a shaft 2 is supported by the dynamic pressure bearings 6,7 provided in a housing 1, the whole of the shaft 2 is received in the housing l and the sealing of the housing 1 can be dispensed with. Since the dynamic pressure bearings 6,7 can utilize the dialysate in the housing 1 as a dynamic pressure generating fluid, it is prevented that the dynamic pressure generating fluid becomes insufficient by providing the dynamic pressure bearings in the housing 1 and the lowering of the life of the dynamic pressure bearings 6,7 is prevented.
