Description

In-vitro catheter fixator for transradial approach hepatic artery perfusion chemotherapy

Technical Field

The utility model relates to the field of medical equipment, concretely relates to external catheter fixer of transradial artery approach hepatic artery perfusion chemotherapy.

Background

Hepatic artery perfusion chemotherapy (HAIC) is a commonly used treatment for middle and late stage liver cancer, in which a catheter is left in a blood supply artery of liver cancer through an interventional operation, and chemotherapy is continuously infused through the catheter exposed to the external part of a patient. In the past, HAIC is mostly carried out through femoral artery access, and the patient needs to stay in bed for 24-46 hours, so that many patients cannot tolerate long-time bed rest, and the risk of thrombus and the like caused by long-time braking is increased. Transradial access (TRA) interventions have emerged in recent years and are the primary alternative to traditional transfemoral access (TFA). Radial access HAIC treatment shows great advantages compared to femoral access HAIC treatment, such as low bleeding rate, few complications at the puncture site, low risk of adverse events and reduced all-cause mortality. However, the radial artery access HAIC treatment patient can move freely, and the external part of the indwelling catheter is fixed on the wrist of the forearm, so that the wrist area is small, the mobility is large, the catheter is not easy to fix, and the catheter is easy to displace along with the movement of the wrist.

At present, the external part of the TRA-HAIC indwelling catheter is fixed by mainly sticking the catheter which is manually wound and bent to the forearm of a patient through a sterile operation film. The method has the following defects: 1) The catheter is not easy to be stuck and fixed, especially when the microcatheter is used, the indwelling part outside the catheter body is longer, the area of the forearm is narrow, although the catheter can be bent for sticking, the area occupied by bending the catheter for many times is large, and the catheter is not easy to stick; 2) The bent catheter is easy to be operated by mistake in the sticking process, so that the catheter is bent and damaged and cannot be used for feeding medicine smoothly; 3) The wrist has large mobility, so that the catheter is easy to displace when extending or bending the wrist, and the position of the part in the catheter body is changed in the blood vessel; 4) Because the operation film stickness is big, the pipe is closely glued with the operation film, on one hand, is unfavorable for postoperative adjustment pipe position, and on the other hand peels off the difficulty in the dismantlement process.
