So, visual alarm mode is favorable to the high operation operator of volume to receive alarm signal rapidly, can guarantee the quiet of operating room simultaneously, does not add other noises, effectively improves through the whole quality and the security performance of pipe artery perfusion system 100. The present embodiment provides only one embodiment of the alarm 142, but is not limited thereto.

In one embodiment, referring to fig. 3 and 4, a transcatheter arterial infusion method using the transcatheter arterial infusion system 100 described above includes the steps of:

s10, aspirating the medicament through the second syringe 131;

s20, communicating the second syringe 131 with the micro-catheter 111;

s30, pushing the second injector 131 to inject the medicament into the patient, and observing the visualization and display component 140 to select one set of injection parameters as the preset injection parameters;

s40, after selection, disconnecting the second injector 131 from the micro catheter 111, and communicating the first injector 121 with the micro catheter 110;

s50, activating the injection assembly 121, and setting the preset injection parameters, so that the first injector 121 is filled according to the preset injection parameters.

In the transcatheter arterial infusion method, the transcatheter arterial infusion system 100 is used by first filling the second syringe 131 with a medicament; then, the microcatheter 110 is put in communication with the detection device 130, and then the second syringe 131 is pushed so that the agent is perfused into the artery of the patient, while simultaneously observing the contrast and adjusting the injection technique. At this time, the display module 140 displays injection parameters such as perfusion pressure and flow rate of the medicament obtained by the detection device 130 in real time, and adjusts and obtains and records the optimal preset parameters after manual injection; then operating the injection device 120, setting preset parameters for medicament injection through the injection assembly 122, and then installing the detection assembly 132 on the first injector 121; the injection assembly 122 is then activated such that the injection assembly 122 controls the first injector 121 to inject the agent through the microcatheter 110 and into the artery of the human body. The automatic injection mode effectively avoids medicament injection errors during manual injection at each time, is favorable for avoiding backflow or the situation that the microcatheter 110 is ejected from a artery, and ensures that the parameterization of each injection is automatically carried out. Meanwhile, the automatic injection mode can greatly reduce the labor intensity of an operator, thereby improving the operation efficiency and the operation curative effect.

In one embodiment, referring to fig. 4, S50, the step of activating the injection assembly 121 to set the preset injection parameters such that the first injector 121 is filled according to the preset injection parameters includes:

s51, activating the driving member 1222;

s52, inputting preset parameters to the control piece;

and S53, controlling the driving piece to work through the control piece so as to enable the first injector to be filled according to preset parameters.

Thus, the control element 123 can set the operation parameters of the driving element 1222, so as to adjust the pushing pressure and the pushing speed of the piston 1212 of the first syringe 121, thereby realizing the parametric operation of the injection device 120, satisfying the current clinical requirements, being beneficial to improving the overall quality of the transcatheter arterial perfusion system 100, being further beneficial to promoting the progress of the transcatheter arterial perfusion operation, and improving the operation efficiency.
