Detailed description of the invention
Elaborate to embodiments of the invention below in conjunction with accompanying drawing, the present embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
embodiment
As shown in Figure 1, the present invention includes front end and enter blood vessel 1, check valve 2, blood vessel 3 is entered in rear end, artificial heart 4, trachea 5, cardiac valves 6, go out blood vessel 9, rotating shaft 10, swivel plate 11, expansion link 12, control volume 13, first moving body 14, second moving body 15, first spring 16, second spring 17, first connection tube 18, second connection tube 19, the blood in-out mouth of check valve 2 enters the blood outlet of blood vessel 1 respectively with front end, the blood inlet that blood vessel 3 is entered in rear end is connected, and cardiac valves 6 is arranged in artificial heart 4, and cardiac valves 6 is divided into air chamber 7 and blood chamber 8 two parts artificial heart 4, and trachea 5 is connected with air chamber 7, and the blood outlet of blood vessel 3 is entered in rear end, the blood inlet going out blood vessel 9 is all connected with blood chamber 8, the cross section that blood vessel 3 is entered in rear end is rectangle, rotating shaft 10 is embedded in rear end and enters on the upper wall surface of blood vessel 3, one end and the rotating shaft 10 of swivel plate 11 are consolidated, the other end of swivel plate 11 and one end of expansion link 12 hinged, the first moving body 14, second moving body 15 is arranged in control volume 13, first moving body 14 is arranged in the upper end of the second moving body 15, being combined by domatic structure of the lower surface of the first moving body 14 and the upper end of the second moving body 15, the other end of expansion link 12 enters blood vessel 3 upper wall surface through rear end successively, hinged with the lower wall surface of the second moving body 15 after control volume 13 lower wall surface, the first spring 16 is arranged in the left wall of the first moving body 14, between the left wall of control volume 13, the second spring 17 is arranged in the lower wall surface of the second moving body 15, between the lower wall surface of control volume 13, one end and the front end of the first connection tube 18 are entered blood vessel 1 and are connected, the other end of the first connection tube 18 is connected with the cavity volume on the left of the first moving body 14, one end of second connection tube 19 with go out blood vessel 9 and be connected, the other end of the second connection tube 19 is connected with the cavity volume on the right side of the first moving body 14.
In work process of the present invention, when the pressure in air chamber 7 is less, cardiac valves 6 pops up, and the volume of blood chamber 8 becomes large, pressure diminishes, check valve 2 is opened, and blood enters blood vessel 1 successively through front end, check valve 2, rear end are entered blood vessel 3 and flowed into blood chamber 8; When the pressure in air chamber 7 is larger, cardiac valves 6 is upspring downwards, and the volume of blood chamber 8 diminishes, pressure becomes large, and check valve 2 is closed, and blood flows out blood chamber 8 through going out blood vessel 9.When front end enters that in blood vessel 1, pressure is larger, the pressure reduction that front end enters blood vessel 1, go out between blood vessel 9 is also larger, first moving body 14 moves right and first spring 16 that stretches, second moving body 15 moves down and compresses the second spring 17, swivel plate 11 turns clockwise, the aditus laryngis that blood vessel 3 is entered in rear end diminishes, and enters the oligemia of blood chamber 8, thus the hemorrhage pressure of using blood vessel 9 diminishes; When front end enters that in blood vessel 1, pressure is less, the pressure reduction that front end enters blood vessel 1, go out between blood vessel 9 is also less, under the action of the spring, first moving body 14 is moved to the left, the second moving body 15 moves up, swivel plate 11 is rotated counterclockwise, the aditus laryngis that blood vessel 3 is entered in rear end becomes large, and the blood volume entering blood chamber 8 increases, thus the hemorrhage pressure recover of using blood vessel 9 is normal.
