Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Close embodiment, the present invention is expanded on further.
As it is shown in figure 1, a kind of ventricle subsidiary conduit pump, left ventricle 1 is connected with aorta 3 by aortic valve 2, conduit 4
Inserting in aorta 3, one end is connected with power set 7, and the other end is free end 5, and free end 5 end just stretches out aortic valve
2, at free end 5 end, check valve 16 is installed, can with freedom of entry end 5 certainly by the blood in check valve 16 left ventricle 1
Can not be entered left ventricle 1 by the blood in end 5, be provided with piston 17 in free end 5, piston 17 is by connecting rod 18 and power set
7 connect, and power set 7 drive piston 17 to move up and down in free end 5, and free end 5 diameter is more than conduit 4 diameter itself, with
Liquid of having blood in stool is stored in free end, it is ensured that blood supply amount in whole conduit 4, and free end 5 is positioned at below piston 17 and aorta
Blood flow section 10 between above lobe 2, blood flow section 10 is positioned at that same cross section is circumferentially spaced arranges porose 11, and hole 11 opening is oblique
On, the blood in free end 5 flows to aorta 3 by hole 11, is provided with sealing device in blood flow section 10, this sealing device with
Piston 17 lower end connects the open and close that can realize hole 11, thus realizes the blood in free end 5 by hole 11 along upwards
Direction flows to aorta 3 or stops flowing to aorta 3, blood flowing during auxiliary left ventricle 1 nonfunction, it is ensured that sufficient blood
Liquid circulation between aorta 3 and left ventricle 1.It is positioned at aortic valve 2 upper end and pace-making seal wire 6, pace-making seal wire 6 and pace-making are set
Device 8 connects, and pacemaker 8 is connected with controller 9, and controller 9 is connected with power set 7, controls left ventricle 1 by pacemaker 8 and jumps
Dynamic frequency, it is achieved this catheter pump works asynchronously with left ventricle 1.
When pacemaker 8 control left ventricle 1 shrink time, signal is passed to controller 9 by pacemaker 8, and controller 9 controls power
Device 7 drives piston 17 to move upward and simultaneously closes off sealing device, and the blood in left ventricle 1 flows to aorta 3, simultaneously blood from
In the check valve 16 freedom of entry end 5 of free end 5 end；When pacemaker 8 controls left ventricle 1 diastole, signal is passed by pacemaker 8
Passing controller 9, controller 9 controls power set 7 and drives piston 17 to move downward simultaneously to open sealing device, and blood is from freedom
Hold the hole 11 in 5 blood flow sections 10 to enter in aorta 3, thus complete a circulation.
Fig. 2 is an embodiment of this sealing device, and in this embodiment, sealing device includes annular rotating shaft 13 and cover plate
12, annular rotating shaft 13 is being positioned at bottom blood flow section 10, and cover plate 12 one end is connected with free end 5 by annular rotating shaft 13 and can
Rotating along annular rotating shaft 13 thus cover hole 11 or open hole 11, annular rotating shaft 13 is by draw bar 19 and piston 17 lower end
Connect, by it serves somebody right 17 up and down motion drive annular rotating shaft 13 to rotate and then cover hole 11 or open hole by cover plate 12
11.When power set 7 drive piston 17 to move downward, cover plate 12 is opened, and blood enters in aorta 3 from free end 5；When dynamic
When power apparatus 7 drives piston 17 to move upward, cover plate 12 is closed, and blood is from the check valve 16 freedom of entry end 5 of free end 5 end
In.
Fig. 3,4 being two other embodiment of this sealing device, in this embodiment, sealing device is one to be placed in free end 5
The hollow circular cylinder 14 of inwall, hollow circular cylinder 14 side arranges the through hole (in figure be not drawn into) corresponding with hole 11, described through hole
Obliquely, hollow circular cylinder 14 upper end is connected opening with piston 17 lower end, under power set 7 act on along free end 5 inwall
Lower movement, when the through hole on hollow circular cylinder 14 side overlaps with hole 11 or partially overlaps, blood enters main from free end 5
Tremulous pulse 3.When power set 7 drive piston 17 to move downward, the through hole on hollow circular cylinder 14 side overlap with hole 11 or
Partially overlapping, the blood in conduit 4 enters in aorta 3 from free end 5 port；When power set 7 drive piston 17 upwards to transport
Time dynamic, the through hole on hollow circular cylinder 14 side is misaligned with hole 11, and blood is from check valve 16 freedom of entry of free end 5 end
In end 5.
The difference of Fig. 4 with Fig. 3 is, in Fig. 3, hollow circular cylinder 14 is normal plane shape towards free end 5 bottom, and
In Fig. 4 hollow circular cylinder 14 towards free end 5 bottom for making towards center curvature shape and by elastomeric material, hollow circular cylinder 14
When piston 17 drives and moves downward, bending bottom merges to be drawn close, and anti-Hemostatic Oral Liquid enters, and plays double protective effect, hollow circle
Cylinder 14 is when piston 17 drives and moves upward, and bending bottom is separately.
