Intraperitoneal hyperthermic perfusion catheter fixing device for ovarian cancer treatment

Abstract

The invention provides an intraperitoneal hyperthermic perfusion catheter fixing device for ovarian cancer treatment, which comprises a support fixed on the abdomen of a human body, a plurality of guide tubes are arranged on the support, hose joints are arranged at the first ends of the guide tubes, each group of hose joints is connected with a group of catheters, a group of self-sealing components are arranged at the second ends of each group of guide tubes, each self-sealing component comprises a tube body and a sealing plug, the first end of the tube body is communicated with the guide tubes, a sealing opening is formed in the second end of the tube body, and the sealing plug is detachably sealed in the sealing opening; an extension section communicated with the lower end of the sealing opening is further arranged in the tube body, a group of sealing plates are further hinged to the inner side of the tube body, tension springs are arranged between the sealing plates and the inner wall of the tube body, and the sealing plates are promoted to be attached to the lower end of the extension section through the tension springs; and according to the intraperitoneal hyperthermic perfusion catheter fixing device, a self-sealing effect can be conveniently formed on a pipeline of the catheter, and in the intraperitoneal hyperthermic perfusion process, the possibility of seepage of liquid in the intraperitoneal cavity is reduced.

Description

technical field [0001] The invention relates to the field of auxiliary instruments for abdominal hyperthermia perfusion, in particular to an intraperitoneal hyperthermic perfusion catheter fixing device for treating ovarian cancer. Background technique [0002] Ovarian cancer is a malignant tumor of the reproductive system that seriously threatens women's lives. More than 70% of the patients are in the advanced stage when clinically diagnosed, and its dissemination and metastasis are mainly located in the abdominal cavity. Intraperitoneal chemotherapy is an important way of chemotherapy for ovarian cancer; It is carried out by means of thermal perfusion, that is, at least two catheters are implanted into the abdominal cavity of the human body by puncture, and the chemotherapy liquid is injected into the abdominal cavity along one of the catheters, and discharged along the other catheter to form a circulation with the external chemotherapy pump ;During the injection process, ...

AI Technical Summary

Problems solved by technology

[0003] Usually, in order to fully clean the various parts of the abdominal cavity with the chemotherapy liquid, it is necessary to puncture multiple catheters in the abdominal cavity of the human body. Therefore, clinically, it is necessary to pull out and replace the catheter pipeline several times. During the catheter replacement process, it is necessary to seal the catheter that does not participate in the circulation. The existing catheter does not have a self-sealing effect. , because there is a certain pressure difference in the abdominal cavity, it is easy to make the body fluid leak out along the catheter
