In-vitro catheter collector for hepatic artery perfusion chemotherapy via radial artery approach

Abstract

The invention relates to an in-vitro catheter collector for hepatic artery perfusion chemotherapy via a radial artery approach, and belongs to the technical field of medical instruments. The in-vitro catheter collector comprises a sterile elastic sponge body and an HAIC indwelling catheter network groove, a radial artery vessel sheath side branch tube groove, a fixing snap clip and a radial artery vessel sheath base groove that are formed in the sterile elastic sponge body. The radial artery vessel sheath base groove is respectively connected with the HAIC indwelling catheter network groove and the radial artery vessel sheath side branch tube groove. A radial artery vessel sheath side branch tube and an HAIC indwelling catheter are arranged in the fixing snap clip. According to the invention, in-vitro catheters for hepatic artery perfusion chemotherapy via the radial artery approach is simple and convenient in operation process and easy to assemble and disassemble. The in-vitro catheter collector integrates multiple functions of collection, sterile protection, fixation and adjustment of HAIC indwelling catheters via the radial artery approach, and meets various clinical requirements at present.

Description

technical field [0001] The invention relates to an extracorporeal catheter collector for radial artery approach hepatic artery perfusion chemotherapy, which belongs to the technical field of medical devices. Background technique [0002] Hepatic arterial infusion chemotherapy (hepatic arterial infusion chemotherapy, HAIC) is a catheter placed behind the blood supply artery of liver cancer through interventional operation, indwelling in the patient's body and giving continuous chemotherapy drug infusion through the catheter exposed outside the patient's body to treat advanced cancer. important approach to liver cancer. HAIC can be accessed through the radial artery or the femoral artery. Compared with the femoral artery approach that requires continuous bed rest for 24-46 hours, the radial artery approach is more convenient and comfortable due to the freedom of movement of the patient. It is increasingly being chosen by clinicians and patients. At present, the external part...

Problems solved by technology

This method has the following hidden dangers: on the one hand, if the catheter is twisted and bent during the infusion of chemotherapy drugs, the drug cannot be fed smoothly. Due to the stickiness between the surgical film and the catheter, it is difficult for clinicians to completely peel off the catheter for adjustment. The position or direction of the catheter, especially when the microcatheter is used in the operation and the indwelling part outside the body is very long, it is more difficult to peel off; on the other hand, it is easy to misuse during the pasting process, so that the catheter is bent and damaged and cannot be smoothly injected

In addition, there will also be cases where the catheter prolapses due to improper arm force.

Either of the above situations can only be solved by resetting the HAIC catheter, which makes both doctors and patients exposed to X-rays, and the operation cost of patients is significantly increased.
