Abstract

The arterial perfusion device comprises a catheter, a connecting pipe, a radiography guide wire and a detector, a fixing plate is installed outside the radiography guide wire, and a backflow prevention mechanism is arranged in the catheter; the anti-backflow mechanism comprises blocking soft films symmetrically arranged in the guide pipe, one ends of the two blocking soft films are movably connected with the exterior of the guide pipe, the exterior of the blocking soft films are attached to the exterior of the fixing plate, and a flow adjusting mechanism is further arranged in the guide pipe; through cooperative use of a first air bag and a flow adjusting soft film in the flow adjusting mechanism, the infusion speed can be adjusted and controlled in the process of medicine infusion, liquid medicine impacts the flow adjusting soft film outwards during infusion, the flow adjusting soft film moves to the outside of a fixing plate through impact, and therefore the discharging speed of the liquid medicine is reduced, and the infusion speed is increased. In addition, the flow adjusting soft film can drive the first air bag to move in the moving process, so that the first air bag moves towards the interior of the catheter, and impact on the blood vessel in the perfusion process is avoided.

Description

technical field [0001] The invention relates to the technical field of arterial perfusion, in particular to an arterial perfusion device for radiological intervention. Background technique [0002] Arterial infusion chemotherapy is a minimally invasive, safe and less painful tumor treatment method. It refers to the introduction of special catheters, guide wires and other precision instruments into the human body under the guidance of medical imaging equipment to locally treat tumors in the body. This treatment uses digital technology to expand the doctor's field of vision. With the help of catheters and guide wires, the doctor's hands are extended. Its incision (puncture point) is only the size of a grain of rice. Tumor diseases that must be treated with surgery or with poor medical treatment. [0003] Arterial infusion chemotherapy can combine several of the most effective anticancer drugs, find the feeding artery of the tumor through catheter technology, and inject antica...
