Referring to fig. 1, 2, 3, and 4, an embodiment of the present application provides an artificial heart piston smooth operation structure, where the drawing set includes a cylinder block 3, a track chute 1, a bull's eye 2, a piston top plate 4, a ventricular soft bag 5, a piston side plate 6, a support frame 7, an artificial heart battery 9, an artificial heart receiving power coil and intelligent induction chip 10, an artificial heart ventricle 11, and a driving member connecting rod 12, which are disposed in a cavity of the cylinder block 3. And an artificial cardiac blood vessel 8 provided on top of the cylinder 3.

In fig. 1, 2 and 3, there are two cylinders 3, and the shape of the cylinder 3 may be a rectangular parallelepiped, a cylinder, an irregular shape, or the like. The track chute 1, the bull eye 2, the piston top plate 4 and other structural components can be arranged in the cavity of the cylinder body.

The track chute 1 is vertically arranged on the inner wall of each cylinder body. The shape of the track sliding chute 1 may be C-shaped, or the track sliding chute 1 may be designed into another shape of guide rail according to design requirements during the implementation process, and the shape of the track sliding chute 1 is not particularly limited herein. The shape and size of the piston top plate 4 and the piston side plate 6 are matched with the shape and size of the cylinder cavity.

Referring to fig. 4, the supporting frame 7 is disposed in the piston side plate, and the upper end thereof is fixedly connected to the piston top plate 4.

The lower end of the support frame 7 is fixedly connected with the bull eye 2, the bull eye 2 is in sliding connection with the track chute 1, and the bull eye 2 can slide up and down along the track chute 1 in a reciprocating manner; because the piston top plate 4 is connected with the ventricle soft capsule 5 in an adhering way, the ventricle soft capsule 5, the piston top plate 4, the support frame 7 and the bull's eye 2 are connected in series.

The driving part connecting rod 12 is connected with the piston top plate 4, and the driving part connecting rod 12 is used for controlling the piston top plate 4 to reciprocate up and down. When the piston top plate 4 reciprocates, the piston top plate 4 applies work to the ventricular soft capsule 5, and the ventricular soft capsule 5 moves upwards/downwards under the traction of the piston top plate 4, so that the artificial cardiac ventricle 11 formed by the cavity in the ventricular soft capsule 5 contracts and expands to simulate the blood pumping function of the human heart.

In alternative embodiments of the present application, the piston top plate 4 is a circular or elliptical plate, and may also be a hemispherical shell shape protruding upward, or the like.

Preferably, the driving member connecting rod 12 is driven by the micro motor to drive the crankshaft to provide kinetic energy, i.e. the micro motor transmits the kinetic energy to the driving member connecting rod 12 through the gear and the rotating crankshaft, and the driving member connecting rod 12 drives the piston top plate 4 to reciprocate up and down. It should be understood that the above description is only one example of the drive member link 12, that the drive member link 12 may have other configurations, and that the specific configuration of the drive member link 12 is not important to the present application and will not be described in detail herein.

In an alternative embodiment of the present application, the top of the cylinder 3 may be provided with a plurality of one-way valves and an artificial cardiac blood vessel 8, and the artificial cardiac blood vessel 8 is communicated with the artificial cardiac ventricle 11 through the one-way valves. The piston top plate 4 drives the ventricular soft bag 5 to do up-and-down reciprocating motion, blood can be continuously discharged and sucked, and then the blood flows into/out of the artificial cardiac ventricle 11 from different artificial cardiac blood vessels 8 through different valves, so that different flow directions of the blood can be realized.

In the process of reciprocating motion of the piston top plate 4, the piston top plate 4 drives the bull eye 2 to move along the track sliding chute 1 through the supporting frame 7. The track chute 1 can limit the movement direction and track of the bull's eye 2, and plays a role in guiding the bull's eye 2. Through setting up track spout 1, bull's eye 2 and support frame 7, can strengthen the part (for example piston roof 4) that drives artificial heart ventricle 11 systolic relaxation in the artificial heart piston even running structure intelligence when doing reciprocating motion and do steadily the same with the bull's eye, fixed up-and-down motion, thereby its stability has been improved, the relatively poor problem of stability when carrying out the up-and-down motion of the part that drives artificial heart ventricle 11 systolic relaxation in the artificial heart piston even running structure has been solved, make ventricle soft bag 5 can smoothly contract the relaxation, artificial heart ventricle 11 systolic relaxation effect has been improved.

To further allow the ventricular soft-bag 5 to contract and relax more smoothly, it should be understood that the bull's eye 2 and the chute should be installed without gaps.

Alternatively, the piston top plate 4 and the cylinder 3 have a spacing therebetween that is constant as the piston top plate 4 reciprocates up and down within the cylinder 3. During specific implementation, when the bull's eye 2 is restricted in the chute of the track chute 1 and can only do vertical up-and-down motion, the piston top plate 4 can keep vertical linear up-and-down motion in the same posture when pushing and pulling the ventricular soft capsule 5, and can not be deviated to the left or right, so that the distance between the piston top plate 4 and the inner wall of the cylinder body can be kept unchanged all the time, and smooth contraction and relaxation of the ventricular soft capsule 5 can be ensured.

The ventricular soft capsule 5 vertically moves up and down along the inner wall of the cylinder 3 through the bull's eye 2, the support frame 7 and the piston top plate 4 under the driving of the driving piece connecting rod 12.

In concrete implementation, the cylinder body 3 can be cylindrical, and the inner wall of the cylinder body is smooth, so that when the ventricular soft capsule 5 is attached to the inner wall of the cylinder body 3, friction is reduced.

In the embodiment of the application, the cylinder body 3 can seal and protect the moving of the ventricular soft capsule 5, and the service life of the piston smooth running structure of the artificial heart can be prolonged.

With continued reference to fig. 2, in order to avoid frictional contact between the ventricular soft capsule 5 and other components disposed in the cylinder body, in an alternative embodiment of the present application, the track chute 1 may be replaced by a vertical groove recessed outward from the symmetrical inner wall of the cylinder body 3, and the bull's eye 2 may also slide deep into the groove, so as to avoid frictional contact between the track chute 1 and the ventricular soft capsule 5.

With continued reference to fig. 4, the piston side plate 6 is located at the lower side of the outer edge of the piston top plate 4, the piston side plate 6 is perpendicular to the piston top plate 4, and the piston top plate 4 and the piston side plate 6 form a piston cap which is cylindrical and has an open bottom. The driving piece connecting rod 12 and the supporting frame 7 are connected through the piston top plate 4.

During specific implementation, under the driving of the driving piece connecting rod 12, the piston top plate 4 pushes or pulls the ventricular soft capsule 5 to reciprocate up and down, the piston top plate 4 moves up and down at a certain interval along the inner wall of the cylinder body 3 through the bull eye 2 and the supporting frame 7, and the constant distance space between the cylinder body 3 and the piston side plate 6 plays a role in protecting and guiding the ventricular soft capsule 5.

In the embodiment of the application, when the bull's eye 2 is restricted in the spout of track spout 1 and can only be perpendicular up-and-down motion, can make piston roof 4 keep perpendicular up-and-down motion with same gesture when pushing away, pulling ventricle soft bag 5, this can make piston roof 4 and piston curb plate 6 and cylinder inner wall have the invariable interval all the time to guarantee that ventricle soft bag 5 can have just suitable space in this interval and carry out the deformation motion.

Alternatively, the distance should be greater than the value of twice the thickness of the capsule skin of the ventricular soft capsule 5.

In concrete implementation, when the piston top plate 4 runs upwards, the lower end part of the ventricular soft capsule 5 is lifted upwards, and the part of the side surface of the ventricular soft capsule 5, which is close to the cylinder body 3, is shaped into a U-shaped structure by the piston top plate 4 continuously. That is, the part of the ventricular soft capsule 5 is folded between the piston side plate 6 and the cylinder 3, and the width of the folded part is larger than the value of two times of the thickness of the capsule skin of the ventricular soft capsule 5.

In the embodiment of the application, the thickness value of the two times of the capsule skin of the interval greater than the ventricular soft capsule 5 is used, so that the condition that the ventricular soft capsule 5 is abraded too fast due to friction is avoided, the condition that the piston top plate 4 does work due to severe friction is avoided, and the service life of the piston smooth running structure of the artificial heart is prolonged.

Further, the artificial heart battery 9 is arranged in the cavity of the stable operation structure of the artificial heart piston, and the artificial heart battery 9 can be wirelessly charged through the charging equipment arranged outside the human body. The artificial heart battery 9 is connected with the micro motor, and the artificial heart battery 9 transmits kinetic energy to the driving piece connecting rod 12 through the micro motor for driving the piston top plate 4 in a reciprocating mode, and the piston top plate 4 further applies work to the ventricular soft capsule 5.

The cavity of the steady operation structure of the artificial heart piston provided by the embodiment of the application is also internally provided with an artificial heart receiving power coil, an intelligent induction chip 10 and other data acquisition devices. The artificial heart receiving power coil and the intelligent induction chip 10 are used for receiving power and analyzing and processing working data of the operation of the artificial heart, and can transmit the working data to power supply and monitoring equipment outside a human body in a wireless transmission mode for the normal operation of the artificial heart. Since this is not the subject of the present application, it will not be described in detail herein.
