[0031] As shown Figures 1-3 in the figure, the present utility model provides an automatic flushing device for a hemoperfusion cartridge, including a bottom plate 1 and a telescopic support frame 2 disposed on the bottom plate 1. The telescopic support frame 2 can change the height of the device according to the flushing requirements. A clamping member 3 is detachably connected to the telescopic support frame 2, which facilitates the disassembly and assembly of the installation components. A foldable installation beam 4 is connected to the clamping member 3, which can fold and store the installation components. An installation groove 41 is provided at the head of the installation beam 4, and a hemoperfusion cartridge body 6 is installed in the installation groove 41. The hemoperfusion cartridge body 6 is installed at the head of the installation beam 4 by using the installation groove 41, which can firmly fix the hemoperfusion cartridge body 6 and ensure the orderly progress of the flushing work. A knocking rod 9 for repeatedly knocking the hemoperfusion cartridge body 6 is also connected to the head of the installation beam 4. The knocking rod 9 can knock the hemoperfusion cartridge body 6 to fully discharge the air therein. Waste liquid barrels 7 and flushing liquid bags 5 are respectively connected to the upper and lower sides of the hemoperfusion cartridge body 6. The flushing liquid bag 5 is filled with physiological saline for flushing the hemoperfusion cartridge body 6. The physiological saline therein is used to flush the hemoperfusion cartridge body 6, and the waste liquid after flushing is collected through the waste liquid barrel 7.

A first liquid pipe 51 is connected between the bottom of the flushing liquid bag 5 and the hemoperfusion cartridge body 6, and a first flow control valve 52 is provided on the first liquid pipe 51.

[0033] As an optimized technical solution of the present utility model, by the telescoping of the telescopic support frame 2, the height of the hanging hook 21 can be changed, and thus the height of the flushing liquid bag can be changed. The physiological saline in the flushing liquid bag 5 flushes the hemoperfusion cartridge body 6 from the bottom along the first liquid pipe 51 by its own gravity, and the flushing amount of the flushing liquid in the first liquid pipe 51 is controlled by the first flow control valve 52. The first liquid pipe 51 is connected to the bottom of the hemoperfusion cartridge body 6 through a first connector 62 to facilitate the installation and fixation of the first liquid pipe 51.

[0034] In the above solution, a second liquid pipe 71 is connected between the waste liquid barrel 7 and the top of the hemoperfusion cartridge body 6, and a second flow control valve 72 is provided on the second liquid pipe 71.

[0035] As an optimized technical solution of the present utility model, after the hemoperfusion cartridge body 6 is flushed from the bottom with physiological saline, the flushing physiological saline waste liquid can be discharged from the top of the hemoperfusion cartridge body 6 and discharged into the waste liquid barrel 7 along the second liquid pipe 71, and the waste liquid flow in the second liquid pipe 71 can also be controlled by the second flow control valve 72. The second liquid pipe 71 is connected to the top of the hemoperfusion cartridge body 6 through a second connector 61 to facilitate the installation and fixation of the second liquid pipe 71.

[0036] In the above solution, the clamping member 3 includes a first arc-shaped clamping plate 31 and a second arc-shaped clamping plate 32. The first arc-shaped clamping plate 31 and the second arc-shaped clamping plate 32 are fixedly connected to the telescopic support frame 2 by bolts. A connecting plate 33 is arranged on the outer side of the second arc-shaped clamping plate 32. An activity groove 331 is arranged at the free end of the connecting plate 33. The tail of the mounting beam 4 is movably connected in the activity groove 331.

[0037] As an optimized technical solution of the present utility model, the first arc-shaped clamping plate 31 and the second arc-shaped clamping plate 32 can be butt-jointed and buckled on the telescopic support frame 2 to realize the installation and fixation of the clamping member 3, so as to facilitate the installation of the mounting beam 4, and enable the mounting beam 4 to move or rotate in the activity groove 331 to reach the working state or the storage state.

[0038] In the above solution, sliding grooves 332 are respectively arranged on both sides of the activity groove 331. Rotating grooves 333 are arranged at the outer ends of the sliding grooves 332. Sliding blocks 44 are respectively arranged on both sides of the tail of the mounting beam 4. The sliding blocks 44 are slidably connected in the sliding grooves 332 and are rotatably connected to the rotating grooves 333. A fastening plate 42 is arranged on the front side inside the mounting groove 41 at the head of the mounting beam 4. A fastening rod 43 penetrates through the front side of the mounting groove 41. The inner end of the fastening rod 43 is rotatably connected to the outer side of the fastening plate 42. The blood perfusion device body 6 is fixed in the mounting groove 41 through the fastening plate 43.

[0039] As an optimized technical solution of the present utility model, the sliding blocks 44 arranged at the tail of the mounting beam 4 can be slidably connected in the sliding grooves 332. When the sliding blocks 44 are located in the sliding grooves 332, the horizontal state of the mounting beam 4 can be ensured, so as to facilitate the fixation of the blood perfusion device body 6. When the sliding blocks 44 slide into the rotating grooves 333, the mounting beam 4 can be turned downward under the action of its own gravity, so as to facilitate the storage of the mounting beam 4.

[0040] In the above solution, a swinging groove 411 is arranged inside the mounting groove 41. The middle part of the knocking rod 9 is rotatably connected in the swinging groove 411, and a torsion spring 92 is arranged at the connection part. A rubber ball 91 is arranged on the outer side of the lower end of the knocking rod 9. A motor 8 is arranged on the top of the mounting beam 4 and is located inside the swinging groove 411. The output end of the motor 8 is connected with an eccentric wheel 81. The eccentric wheel 81 abuts against the upper end of the knocking rod 9.

[0041] As an optimized technical solution of the present utility model, during the flushing process of the blood perfusion device body 6, the motor 8 drives the eccentric wheel 81 to rotate. Under the elastic force of the torsion spring 92, the upper end of the knocking rod 9 will always abut against the eccentric wheel 81. By using the rotation of the eccentric wheel 81, the lower end of the knocking rod 9 can repeatedly knock on the blood perfusion device body 6 in cooperation with the torsion spring 92, so as to exhaust the air in the blood perfusion device body 6 during the flushing process. Due to the presence of the rubber ball 91, the collision between the knocking rod 9 and the blood perfusion device body 6 can be effectively avoided, the generation of noise can be reduced, and the wear of the blood perfusion device body 6 can be reduced, so as to improve its service life.

[0042] Specific implementation case:

[0043] During use, stretch and expand the telescopic support frame 2, and through the docking of the first arc-shaped clamping plate 31 and the second arc-shaped clamping plate 32, connect and fix them with bolts. Fix the clamping member 3 on the telescopic support frame 2, turn the mounting beam 4 upwards, rotate the sliding block 44 to the opening of the sliding groove 332, so that the sliding block 44 moves along the sliding groove 332 into the movable groove 331, and the sliding block 44 slides to the bottom of the sliding groove 332 to ensure the unfolded state of the mounting beam 4.

[0044] Then hang the liquid flushing bag 5 on the hanging hook 21 at the top of the telescopic support frame 2, connect the upper end of the first liquid pipe 51 to the liquid flushing bag 5, and fix the lower end of it at the bottom of the blood perfusion device body 6 through the first connector 62. Connect the lower end of the second liquid pipe 71 to the waste liquid bucket 7, and fix the upper end of it at the top of the blood perfusion device body 6 through the second connector 61. Then the normal saline can enter the blood perfusion device body 6 from the liquid flushing bag 5 through the first liquid pipe 51 from bottom to top for flushing and air exhausting, and the waste liquid after flushing flows into the waste liquid bucket 7 through the second liquid pipe 71.

[0045] During the flushing process of the blood perfusion device body 6, the motor 8 drives the eccentric wheel 81 to rotate. Then, under the action of the torsion spring 92, the upper end of the knocking rod 9 can always abut against the eccentric wheel 81, and then the lower end of the knocking rod 9 can be driven to knock on the blood perfusion device body 6 to exhaust the air in the blood perfusion device body 6 as effectively as possible, ensuring the flushing effect of the blood perfusion device body 6. At the same time, the rubber ball 91 will eliminate the noise generated by the knocking vibration and reduce the wear caused by the knocking, improving the service life of the flushing device.

[0046] After the flushing is completed, the first flow control valve 52 and the second flow control valve 72 can be closed to cut off the liquid in the first liquid pipe 51 and the second liquid pipe 71, and then the flushing work of the blood perfusion device body 6 can be completed instead of manual labor.

[0047] The specific embodiments described above further elaborate on the purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above description is only for the specific embodiments of the present utility model and is not used to limit the protection scope of the present utility model.
