Accurate matching device of trastuzumab and ribavirin for treating gastric cancer

Abstract

The invention discloses an accurate matching device of trastuzumab and ribavirin for treating gastric cancer. The device comprises a piston rod, a needle cylinder, a piston ring, a needle head, a push plate, push rods, outlets, a gear box, racks, gears, connecting rods and sliding blocks, wherein the piston ring is formed in the needle cylinder; the piston rods are mounted on the piston ring; the push plate is mounted on the piston rods; the push rods are respectively mounted on the left side and the right side of the push plate; the lower ends of the push rods extend into the gear box from the outlets; the outlets are formed in the gear box; the gear box is mounted on the left and right sides of the needle cylinder; the racks are mounted under the push rods; the gears are mounted on the side surface of the racks; the gears are mounted on a wheel frame; the wheel frame is mounted on the inner side surface of the gear box; the connecting rods are mounted under the racks; the sliding blocks are mounted on the side surfaces of the connecting rods; the sliding blocks are mounted on slide rails; the slide rails are mounted on the inner side surface of the gear box; and the needle head is arranged on the needle cylinder. The device has the advantages that the precise proportioning of the liquid medicine can be realized by controlling the moving distance of the rack and further controlling the volume of the liquid absorbed by the needle head.

Description

technical field [0001] The invention relates to a device for precisely proportioning trastuzumab and ribavirin for treating gastric cancer, and belongs to the technical field of medical equipment. Background technique [0002] Targeted drugs have the advantages of strong specificity, obvious curative effect and less side effects, and have become the latest research hotspot in tumor treatment. Trastuzumab is a humanized monoclonal antibody drug targeting human epidermal growth factor receptor 2, HER2, which can block the cell signaling pathway mediated by HER2. HER2 is overexpressed or amplified in 100% of gastric cancer cases, and trastuzumab has become the main treatment for HER2-positive gastric cancer. Ribavirin is a broad-spectrum antiviral drug used to treat human respiratory fusion virus infection, hepatitis C and viral hemorrhagic fever. It has been included in the World Health Organization's list of essential drugs since it was approved by the US FDA in 1998. one t...
