Embodiment 1
[0033] Such as Figure 1-Figure 2 As shown: this embodiment provides a pulsating artificial blood pump, including a driving device, a planar linkage mechanism and a blood pump. The driving device is connected to the blood pump through a planar linkage mechanism, and the blood pump is used to simulate heart pumping.
[0034]The planar linkage mechanism includes a first crank 1, a second crank 2, a first connecting rod 3, a second connecting rod 4, a crossbeam 5 and a rocker 6, one end of the first crank 1 is connected with a driving device, and one end of the first crank 1 The other end is hinged with one end of the first connecting rod 3, the other end of the first connecting rod 3 and one end of the rocking bar 6 are all hinged with one end of the crossbeam 5, the other end of the rocking bar 6 is fixedly connected with the base 7, and the second crank One end of the second crank 2 is connected to the driving device, the other end of the second crank 2 is hinged to one end of...
Embodiment 2
[0042] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the planar linkage mechanism includes a first crank 1, a second crank 2, a first connecting rod 3, a second connecting rod 4, a beam 5 and a rocker 6, and the first One end of the crank 1 is connected with the driving device through a coupling, the other end of the first crank 1 is hinged with one end of the first connecting rod 3, the other end of the first connecting rod 3 is hinged with one end of the crossbeam 5, and the other end of the rocker 6 is hinged. One end is fixedly connected to the base 7, one end of the second crank 2 is connected to the driving device through a coupling, the other end of the second crank 2 is hinged to one end of the second connecting rod 4, and the other end of the second connecting rod 4 is connected to the beam The other end of 5 is hinged, the middle part of beam 5 is hinged with the push rod 8 of the blood pump, one end of rocker 6 is hinged ...
