Dredging device for abdominal cavity hyperthermia perfusion pipeline

Abstract

The invention relates to medical instruments, in particular to a dredging device for an abdominal cavity hyperthermia perfusion pipeline, which comprises a hyperthermia perfusion pipe used for communicating with the abdominal cavity of a patient to form a circulation loop; a flexible balloon which is arranged on the hot infusion tube; one end of the flexible balloon is connected with the hyperthermia perfusion tube, or the inlet end and the outlet end of the flexible balloon are both connected to the hyperthermia perfusion tube, and the flexible balloon is used for stretching out and drawing back or expanding so that the flow speed of fluid in the hyperthermia perfusion tube can be changed. According to the dredging device for the abdominal cavity hyperthermic perfusion pipeline, when the hyperthermic perfusion pipeline is blocked, the flexible balloon is stretched or expanded to enable the flow speed of fluid in the hyperthermic perfusion pipeline to change, and liquid in the balloon can drain residues of the blocked pipeline out of the pipeline, so that the effect of dredging the pipeline is achieved.

Description

technical field [0001] The patent of the present invention relates to medical appliances, in particular to a dredging device for abdominal cavity heat perfusion pipeline. Background technique [0002] Hyperthermic intraperitoneal chemotherapy (HIPEC) is applied to the conservative treatment of patients with advanced peritoneal tumors and peritoneal metastases. It adopts a sophisticated intraperitoneal perfusion therapy system, and usually chooses hot distilled water to add chemotherapy drugs to achieve precise intraperitoneal hyperthermic chemotherapy. Temperature control, circulatory perfusion, through the circulation of constant temperature and heat, let the tumor cells undergo degeneration and necrosis, so as to prevent and treat the implantation and metastasis of abdominal malignant tumors. [0003] In the actual operation process, the pipeline connecting the abdominal cavity is easily blocked by blood clots or tissues, which affects the smoothness of the pipeline. Opera...

Problems solved by technology

[0003] During the actual operation, the pipeline connected to the abdominal cavity is easily blocked by blood clots or tissues, which affects the smoothness of the pipeline. Operators need to repeatedly try to squeeze, disconnect, and rinse the pipeline to clear the pipeline, and the dredging effect is not good

And because the pipeline is perfused with chemotherapy drugs, disconnecting the pipeline connection and flushing the tube may cause medical staff to come into contact with chemotherapy drugs, resulting in occupational exposure
