The invention discloses an environment-friendly interventional drug delivery device for treating liver cancer in the technical field of interventional drug delivery. It includes a base plate, a positioning frame is fixed in the center of the upper surface of the base plate, and the left side of the upper surface of the positioning frame passes through a card slot. A medicine storage box is clamped, and a connector is provided on the right side of the front surface of the positioning frame, and a bracket is fixed and screwed between the connector and the positioning frame. A drug infusion tube is connected between the left top of the connector; the present invention blends the drug liquid into the mixing tank according to the proportion, avoiding the situation that the drug is contaminated by contact with the external environment, and the safety is high, and the drug liquid Stir evenly to play a better role. By manually compressing the air bag, the air pressure between the drug outlet tube and the guide tube changes, so that the drug solution in the connector flows from the drug outlet tube to the guide tube, thereby guiding the flow of the probe to the administration site. , Precise drug administration, saving time and effort in operation.
Description
technical field [0001] The invention relates to the technical field of interventional drug delivery, in particular to an environment-friendly interventional drug delivery device for treating liver cancer. Background technique [0002] Liver cancer is a malignant tumor of the liver, which can be divided into two categories: primary and secondary. Primary malignant tumors of the liver originate from the epithelial or mesenchymal tissues of the liver. The former is called primary liver cancer, which is a malignant tumor with a high incidence in my country and is extremely harmful; rare. Secondary or metastatic liver cancer refers to malignant tumors originating from multiple organs throughout the body and invading the liver. In liver cancer, vascular interventional therapy mainly includes selective hepatic arterial infusion therapy, selective hepatic arterial embolization, and selective hepatic arterial chemoembolization. Its main physiological basis is that 20%-25% of the bl...
