[0039] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0040] Embodiment one:

[0041] In combination with Figures 1 to 3 As shown in the drawings, the embodiment provides a multifunctional blood perfusion device flushing machine. The clamping tool 1 has a row of clamping stations for one-to-one clamping of the perfusion device 2. The upper and lower sides of the clamping tool 1 are arranged with a plurality of symmetrical upper butt joints 31 and lower butt joints 32. The upper butt joints 31 and the lower butt joints 32 are independently connected with a clamping cylinder 33. In use, the clamping cylinder 33 can control the upper butt joints 31 and the lower butt joints 32 to move up and down, so that the upper butt joints 31 and the lower butt joints 32 are connected or separated with the upper and lower ends of the perfusion device 2. After the upper butt joints 31 and the lower butt joints 32 are connected with the perfusion device 2, they are in conduction with the inside of the perfusion device 2. The upper main pipeline 41 is in communication with all the upper butt joints 31. One end of the upper main pipeline 41 is connected with an upper vacuum valve 51, an upper air valve 52, an upper water inlet valve 53, and an upper water outlet valve 54, respectively. The lower main pipeline 42 is in communication with all the lower butt joints 32. One end of the lower main pipeline 42 is connected with a lower vacuum valve 61, a lower air valve 62, a lower water inlet valve 63, and a lower water outlet valve 64, respectively.

[0042] In addition, a pressure maintaining stop valve 7 is installed in the pipeline connecting the upper butt joint 31 and the lower butt joint 32 to the upper main pipeline 41 and the lower main pipeline 42, respectively. When the two pressure maintaining stop valves 7 in the same pipeline are closed, a closed structure is formed between the two pressure maintaining stop valves 7 in the perfusion device 2. A pressure sensor 8 is connected at the upper butt joint 31, which is used to detect the pressure in the closed structure. A pressure maintaining indicating lamp 9 corresponding to the perfusion device 2 is arranged on one side of the clamping tool 1, which is used to display whether the pressure in the closed structure is stable.

[0043] The working process is as follows:

[0044] The perfusion device 2 is placed on the clamping tool 1 one by one. The clamping cylinder 33 controls the upper butt joints 31 and the lower butt joints 32 to move close to the upper and lower ends of the perfusion device 2.

[0045] When flushing, water is fed from the lower water inlet valve 63 and water is discharged from the upper water outlet valve 54. After a certain period of time, the lower water inlet valve 63 and the upper water outlet valve 54 are closed, and then the lower air valve 62 and the upper vacuum valve 51 are opened. After a certain period of time, the residual water in the perfusion device is removed, and the flushing is completed. The flushing frequency can be set according to the needs.

[0046] backflushing, the upper air valve 52 and the lower vacuum valve 61 are opened, and the residual water in the perfusion device is pumped out for a certain time, and the backflushing is completed; the backflushing times can be set according to requirements;

[0047] water pressure detection, the lower water inlet valve 63 is opened, and the upper water outlet valve 54 does not discharge water; when the pressure reaches the set detection pressure value, the lower water inlet valve 63 and the pressure cutoff valve 7 corresponding to each path are closed; the pressure is maintained for a certain time, and the pressure sensor 8 monitors the pressure value; if there is a leakage, the pressure value will decrease; after the pressure maintaining is completed, the green light in the pressure maintaining indicator 9 is bright if there is no leakage, and the red light in the pressure maintaining indicator 9 is bright if there is a leakage;

[0048] After the operation is completed, the clamping cylinder 33 controls the upper and lower butt joints 31 and 32 to move away from each other, and the upper and lower ends of the perfusion device 2 are separated, and the perfusion device 2 is removed for the next process operation.

[0049] The above embodiment can be seen, the utility model can realize automatic clamping, positive flushing, backflushing, water filling and pressure maintaining and leakage detection functions; the upper and lower butt joints are controlled to move up and down by the clamping cylinder, the quick and accurate butt joint and separation with the perfusion device are realized, and the stability and sealing performance in the flushing process are ensured; the positive flushing and backflushing functions are realized by different valve combinations, the interior of the perfusion device can be fully cleaned, the impurities and residues can be effectively removed, and the cleanliness and performance of the perfusion device are ensured; the leakage problem of the perfusion device can be found in time through water filling and pressure monitoring, and the green light and the red light of the pressure maintaining indicator represent the no leakage and leakage states of the perfusion device respectively, which provides intuitive and clear feedback for the operator, and facilitates timely discovery and processing of problems.

[0050] Embodiment two:

[0051] On the basis of the above-mentioned embodiment one, in combination with Figures 1 to 6 As shown in the figure, the embodiment provides a clamping tool 1 with a transposition function, which mainly comprises a sliding plate 11, a driving assembly 12 and a clamping seat 13.

The clamping seat 13 is in a "U" shape, and a through hole is formed in the middle of the clamping seat 13. The clamping seat 13 is fixed to the long hole 111 by bolts. The upper and lower side plates of the clamping seat 13 are provided with arc-shaped grooves for clamping the perfusion device 2. The arc-shaped grooves have a certain elasticity, which facilitates the mounting and dismounting of the perfusion device 2.

[0053] The clamping seats 13 are equidistantly fixed on the slide plate 11, and the clamping seats 13 are divided into two groups arranged alternately. When the slide plate 11 is located at the left work station, one group of clamping seats 13 is opposite to the upper butt joint 31 and the lower butt joint 32 one by one. When the slide plate 11 is located at the right work station, the other group of clamping seats 13 is opposite to the upper butt joint 31 and the lower butt joint 32 one by one. In this way, when one group of clamping seats 13 is working, the other group of clamping seats 13 can mount and dismount the perfusion device 2, thereby improving the detection efficiency and equipment utilization.
