[0044] When the hose 12 is in contact with the force detection pipe clamp assembly 7, first, the hose 12 is installed through the elastic push plate 72 installed at one end of the auxiliary frame 71, when the hose 12 approaches the elastic push plate 72, the elastic push plate 72 is turned inward, when the distance between the two groups of elastic push plates 72 is greater than the diameter of the hose 12, the hose 12 enters the space formed between the auxiliary frame 71 and the elastic push plate 72, after the hose 12 enters the inside of the auxiliary frame 71, the elastic push plate 72 is reset under the action of the elastic force, then the hose 12 starts to contact with the power wheel 73, at the same time, the position of the sliding block 74 on the fixed frame 67 is adjusted according to the length of the syringe 9, because the sliding block 74 slides on the fixed frame 67 with damping, so it remains fixed without external force, then the hose 12 at one end of the connecting head 11 is placed between the upper and lower two groups of rubber clamping plates 77, then the moving block 76 connected with the guide rail groove 75 is adjusted, so that the rubber clamping plate 77 installed at one end of the moving block 76 continuously contacts the hose 12, the two groups of rubber clamping plates 77 are elastically connected, the hose 12 is clamped after being placed between the two groups of rubber clamping plates 77, the rubber clamping plate 77 stops the movement of the moving block 76 after clamping the hose 12, at this time the hose 12 is clamped and tightly closed, then the stem cell material in the syringe 9 remains stationary, the syringe 9 is pushed to the adjustable clamping assembly 8 until it is clamped, then the blade at one end of the syringe 9 is inserted into the groove of the clamping piece segment of the fixed frame 67, then the other end of the piston push rod 10 is connected with the moving clamping frame 3, then the hose 12 is pulled manually by the medical staff, the power wheel 73 rotates under the movement of the hose 12, when the power wheel 73 installed at the bottom of the auxiliary frame 71 rotates, the hose 12 starts to be transported to one end of the handle 68.

[0051] When the hose 12 is in contact with the force detection pipe clamp assembly 7, first pass the hose 12 through the elastic plate 72 installed on one end of the auxiliary frame 71, when the hose 12 is close to the elastic plate 72, the elastic plate 72 is turned inward, when the distance between the two groups of elastic plates 72 is greater than the diameter of the hose 12, the hose 12 enters the space formed between the auxiliary frame 71 and the elastic plate 72, after the hose 12 enters the inside of the auxiliary frame 71, the elastic plate 72 is reset under the action of the elastic force, then the hose 12 begins to contact with the power wheel 73, at the same time, adjust the position of the slider 74 on the fixed frame 67 according to the length of the syringe 9, because the slider 74 slides on the fixed frame 67 with damping, so it remains fixed without external force, then put the hose 12 on one end of the connector 11 between the upper and lower two groups of rubber clamping plates 77, then adjust the moving block 76 connected with the guide rail groove 75, so that the rubber clamping plate 77 installed on one end of the moving block 76 continuously contacts the hose 12, the two groups of rubber clamping plates 77 are elastically connected, after the hose 12 is put between the two groups of rubber clamping plates 77, the hose 12 is clamped, the rubber clamping plate 77 stops the movement of the moving block 76 after clamping the hose 12, at this time the hose 12 is clamped and tightly closed, then the stem cell material in the syringe 9 remains stationary, then push the syringe 9 to the adjustable clamping assembly 8, until it is clamped into the adjustable clamping assembly 8, then insert the blade on one end of the syringe 9 into the groove of the fixed frame 67 clamping piece, then connect one end of the piston push rod 10 with the moving clamp frame 3, then pull the hose 12 manually by medical staff, the power wheel 73 rotates under the movement of the hose 12, when the power wheel 73 installed at the bottom of the auxiliary frame 71 rotates, the hose 12 begins to be transported to one end of the handle 68, at this time, the curved hose 12 between the auxiliary frame 71 and the rubber clamping plate 77 is gradually straightened, until the hose 12 on one end of the rubber clamping plate 77 is pulled, the detection wheel 78 inside the rubber clamping plate 77 begins to rotate, because the detection wheel 78 transmits electrical signals to the force detector 710, and the force detector 710 transmits electrical signals to the signal line 79, and the signal line 79 transmits power signals back to the control panel 2, so when the detection wheel 78 rotates under the tension of the hose 12, the electrical signals of the detection wheel 78 are transmitted to the force detector 710, then the force detector 710 transmits electrical signals back to the control panel 2 through the signal line 79, then when the force of the detection wheel 78 rotation decreases, the control panel 2 alarms, then stop pulling the hose 12, at this time the power wheel 73 stops rotating, at this time the hose 12 is also in a tense state.
[0052] When the syringe 9 is close to the adjustable clamping assembly 8, the rubber block 84 first contacts one end of the syringe 9, and then the syringe 9 continues to push the rubber block 84 to move inward, at the same time, the disc push rod 83 is pushed to start to extrude the first spring 82 in the hollow pipe frame 81, and at the same time, when the disc push rod 83 moves, the connecting seat 811 installed on the surface of the disc push rod 83 moves together, when the connecting seat 811 moves, the V-shaped support 810 moves together, and when the V-shaped support 810 moves, the roller wheel 88 installed at the top of the V-shaped support 810 starts to slide in the sliding groove of the arc-shaped clamping jaw 87, and the sliding of the arc-shaped clamping jaw 87 extrudes the second spring 89, and at the same time, due to the size of the syringe 9, the roller wheel 88 stops after moving a distance, and due to the size of the V-shaped support 810, the V-shaped support 810 connected with one end of the roller wheel 88 enlarges the opening of the end of the telescopic rod 86, when one end of the V-shaped support 810 is enlarged, the other end of the V-shaped support 810 starts to become smaller, then the V-shaped support 810 flips around the roller wheel 88 as the center, and due to the limiting effect of the telescopic rod 86, the front end of the arc-shaped clamping jaw 87 is closed, and the end of the arc-shaped clamping jaw 87 connected with the telescopic rod 86 is opened, then one end of the arc-shaped clamping jaw 87 pulls the end of the telescopic rod 86 to move and stretch on the upper and lower surfaces of the hollow block 85, and then the flipped arc-shaped clamping jaw 87 drives the arc-shaped block 812 to gradually contact the surface of the syringe 9, and then three-point support is fixed, at this time, the medical staff flips the second wrench 814, when the second wrench 814 is perpendicular to the blocking plate 813, the surface of the second wrench 814 is attached to the surface of the arc-shaped clamping jaw 87, then the threaded locking piece 815 is locked, at this time, the installation and fixation of the syringe 9 are completed, then the parameter of the control panel 2 is set, the device is started, and the stem cell infusion is carried out.
