Transcatheter arterial perfusion system and transcatheter arterial perfusion method

Abstract

The invention relates to a transcatheter arterial perfusion system, and the system comprises an injection device, wherein the injection device comprises a first injector and an injection assembly, the injection assembly is connected with the first injector, and the injection assembly is used for setting injection parameters and pushing the first injector according to preset parameters; a detection device which comprises a second injector and a detection assembly, wherein the detection assembly is used for detecting injection parameters of the medicament; a display assembly which is in control connection with the detection device, wherein the display assembly is used for displaying the medicament injection parameters acquired by the detection device; and a microcatheter which is selectively communicated with the first injector and the second injector. According to the transcatheter arterial perfusion system, errors of medicament injection during manual injection each time are effectively reduced, and the situation that backflow occurs or the micro-catheter pops out of the artery can be avoided. Meanwhile, the labor intensity of an operation operator can be greatly reduced, and the operation efficiency and the operation curative effect are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a transcatheter arterial perfusion system and a transcatheter arterial perfusion method. Background technique [0002] With the development of medical technology, transcatheter arterial infusion chemotherapy technology has emerged. This technology is an important means of tumor interventional therapy, and is often used in ophthalmic artery, hepatic artery and other parts. Among them, transcatheter ophthalmic artery infusion chemotherapy is currently the most cutting-edge technology for the treatment of children with retinoblastoma. The treatment method is to superselect the microcatheter into the ophthalmic artery of the affected side through the femoral artery, and then inject chemotherapy drugs through the microcatheter, so as to achieve the purpose of precise perfusion chemotherapy and greatly reduce side effects. [0003] The key part of transcatheter arterial infusi...

This is prone to subjective bias and cannot guarantee the optimal operation of homogeneity

[0004] In the traditional technology, the pressure, speed and dose parameters can be set for the high-pressure injector for radiography, but it can only be injected in a single injection, and cannot be injected continuously in pulses, and there is no automatic detection and memory parameter device (including hand push pressure, speed and dose), and The minimum pressure value is too high for micro-injection and cannot meet current clinical needs
