Abstract
The present invention discloses a miniature implantable axial-flow type heart assist blood pump, which is composed of a receiver, a coil fixed on the receiver, a shaft fixed in the receiver, a permanent magnet arranged at the outside of the shaft, a rotor impeller arranged at the outside of the permanent magnet and a stator impeller arranged on the shaft. When the coil fixed at the outer wall of the receiver is switched on, the coil can generate magnetic field; the permanent magnet can drive the rotor impeller to rotate together under the mutual function of the magnetic field and the permanent magnet, blood flows in from an inlet end and flows out from an outlet end, so as to generate the needed flow and the pressure, further to substitute part or all of the functions of the natural heart. The prevent invention is characterized by small size, simple structure, low processing cost, simple control system, stable operation, small damages of the blood visible components and less various complications; the present invention can be implanted into the human body; and the present invention has less energy consumption and does not need to be connected with the longer pipeline.
Description
Technical field
The present invention relates to a kind of assistant blood pump for heart that can partly or completely replace the nature cardiac function, specifically, the present invention relates to a kind of minisize axial-flow formula assistant blood pump for heart in can implant into body.
Background technology
Clinically, the patient for heart failure need treat by artificial mechanical's auxiliary device usually.Main heart assistance therapy equipment at present has centrifugal pump and pulsate pump.Existing heart assistance therapy equipment in home and abroad such as pulsate pump and centrifugal pump mainly are non-implantation auxiliary blood pumps, and its inherent disadvantage is: volume is big, and pipeline is long, the control system complexity, and energy consumption is big, and corresponding complication is many.For example: the patient can not voluntary activity, easily forms thrombosis, and the mechanical system fault is many, has seriously influenced the clinical therapeutic efficacy of heart pump.
Summary of the invention
In order to overcome big, the drawback such as can not implant of existing heart-assist device volume, the purpose of this invention is to provide the axial flow type assistant blood pump for heart in a kind of miniature human implantable.
For achieving the above object, the present invention is by the following technical solutions: a kind of Miniature implantable axial flow type assistant blood pump for heart, it by casing, be fixed on coil on the casing, be fixed on the axle in the casing, a permanent magnet that is installed in the axle outside, the impeller of rotor that is installed in the permanent magnet outside and the stator impeller that is installed on the axle and constitute.
Described permanent magnet is positioned at the inside of impeller of rotor, with the impeller of rotor interference fit, and moves with impeller of rotor.
Described stator impeller by bearing fixing on axle, interference fit between bearing and the stator impeller.
Described coil stationary and does not have relative motion with casing on the outer wall of casing, and interference fit between the casing.
Two ends at described axle are separately installed with the stator impeller, and described impeller of rotor is installed between two stator impellers.
Advantage of the present invention: volume is little, and is simple in structure, and processing cost is low; Control system is simple, and running is stable, and blood formed element destroys little, and various complication are few; Human implantable; It is little to consume energy, and need not to connect the longer pipe road.
Description of drawings
Fig. 1 is a perspective view of the present invention;
Fig. 2 is a cross-sectional view of the present invention;
Fig. 3 is an axial side view of the present invention.
The specific embodiment
As Fig. 1～shown in Figure 3, Miniature implantable axial flow type assistant blood pump for heart disclosed by the invention mainly by casing 1, be fixed on coil 2 on the casing, be fixed on axle 3 in the casing, be installed in the permanent magnet 4 of axle 3 outsides, the stator impeller 6 that is installed in the impeller of rotor 5 of permanent magnet 4 outsides and is installed in axle 3 two ends constitutes.
In specific embodiments of the invention, permanent magnet 4 is positioned at the inside of impeller of rotor 5, with impeller of rotor 5 are interference fit, and move with impeller of rotor.Stator impeller 6 is fixed on the axle 3 by bearing 7, also is interference fit between bearing and the stator impeller.Coil 2 is fixed on the outer wall of casing 1, and with casing 1 no relative motion, with casing also be interference fit.
After coil 2 energisings that are fixed on casing 1 outer wall (coil is by the external direct current power supply power supply), coil 2 produces magnetic field; Under the interaction of this magnetic field and permanent magnet 4, permanent magnet drives impeller of rotor and rotates together, and shown in the direction of arrow among Fig. 1, Fig. 2, blood flows into from entrance point and flows out from the port of export, produce the flow and the pressure that need, thus the function of some or all of replacement nature heart.
Advantage of the present invention:
1, volume is little, and is simple in structure, and processing cost is low; Control system is simple, and running is stable, and blood formed element destroys little, and various complication are few.
Because permanent magnet of the present invention is positioned at the inside of impeller of rotor, reduced the volume of blood pump; And, because the present invention is by the interaction between magnetic field, make the impeller of rotor rotation in the blood pump, thereby make blood flow, so control system of the present invention is simple, running is stable, has avoided because volume is big, the generation of the complicated various complication of bringing of control system.
2, human implantable.
Because volume of the present invention is little, control system is simple, and it is reliable and stable to turn round, so can be easily by in the operation implant into body.
3, power consumption is little, need not to connect the longer pipe road.
The above is specific embodiments of the invention and the know-why used, and is any based on the equivalent transformation on the technical solution of the present invention basis, all belongs within the protection domain of the present invention.
