Abstract
The utility model relates to a driving impeller for a whole-artificial heart blood pump without a bearing, a motor and a shaft, which belongs to the technical field of biomedical engineering. The circular column surface of a column impeller in the device is provided with a column leaf blade, the right side end of the column impeller is provided with an axially controlled disc, the impeller self is designed into a rotor of the motor, a periphery magnetic suspension bearing is designed into a stator of the motor and the bearing can realize the driving action to the impeller. The impeller does not need to be supported by the bearing, and driving force does not need to be transferred by the shaft. The column leaf blade has two actions that the column leaf blade is used as a leaf blade for pushing blood to flow out of a blood pump; the column leaf blade is used as a driven rotor component of the motor. In the blood pump, the axially controlled disc 2 achieves the action that the axial control of the impeller is realized through the cooperation of the axially controlled disc 2 and an axial control coil. The utility model has the advantages that a dead angle structure of blood flow is avoided, k the chance of the generation of thrombus existing in the existing artificial heart blood pump impeller is reduced and the impeller with highly integrated functions enhances the transportability of the artificial heart blood pump.
Description
Technical field
This utility model relates to a kind of drives impeller that is used for the complete artificial heart pump of bearing free, engine free and axle free, belongs to the biomedical engineering technology field.
Background technology
At present, the kinds of artificial heart has been applied to clinical.Wherein increasing artificial heart blood pump begins to adopt not directly by the axle transmission of drive force with not directly by the magnetic levitation technology of bearings impeller, avoids causing owing to the existence of bearing and shaft sealer the generation of thrombosis.The existence of bearing is all arranged in typical blood pump blade wheel structure or the impeller adnexa.Be provided with radial ball bearing 13 in Fig. 1 (U.S. Biomedicus centrifugal pump) device, this position has increased the chance that thrombosis produces.Be provided with the axial plain bearing that is made of central shaft 8 and axle sleeve 9 in Fig. 2 (application number is 98226532.8 patent) device, sliding bearing structure is a blood flow dead angle, increases the chance that thrombosis produces equally.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing artificial heart blood pump impeller to have the problem that produces thrombosis, and a kind of drives impeller that is used for the complete artificial heart pump of bearing free, engine free and axle free is provided.
A kind of drives impeller that is used for the complete artificial heart pump of bearing free, engine free and axle free of the present utility model is implemented according to technical scheme shown in Figure 3.It is characterized in that: the face of cylinder of column type post impeller 1 is provided with the post blade 3 more than 2 of symmetric arrangement.The right-hand end of post impeller 1 is provided with axially and is manipulated stock quotations 2.
Effect of the present utility model and duty are: the post impeller itself is designed to the rotor of motor, and the magnetic suspension bearing of periphery is designed to the stator of motor, make this bearing can realize driving effect to impeller.The impeller of this no back shaft structure does not need bearings, need not the axle transmission of drive force.The support of impeller comes from the active magnetic suspension bearing (not shown) of periphery, and it is with impeller comprehensive suspension on 6 degree of freedom.2 post blades, the 3 usefulness ferromagnetic materials of the symmetric arrangement that is provided with on the face of cylinder of post impeller 1 process.Post blade 3 has two effects: the one, and as blade, promote blood flow and go out blood pump; The 2nd, as the driven rotor part of motor, by the variation magnetic field drives impeller rotation of outer driving coil (not shown).In blood pump, the axial quilt of the ferromagnetic material of impeller 1 right-hand end setting is manipulated stock quotations and 2 is played to cooperate with axial control coil (not shown) and realize that impeller shaft is to the effect of controlling.
The utility model has the advantages that: at first avoided blood flow dead angle structure, reduced the chance that existing artificial heart blood pump impeller exists thrombosis to produce.Next is that this impeller function height is integrated promptly has driving to control, promote blood flow and axial suspension control function, improved functions of components efficient and reduced the parts overall volume again, made the complete artificial heart pump of bearing free, engine free and axle free improve portability.
