Embodiment Construction

[0013] The implementation process of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] see figure 1 shown. The therapeutic apparatus of the present invention is composed of an arterial pressure gauge 1, a heparin pump 2, a blood pump 3, an inflow pressure gauge 4, a core filter 5, a degassing system 10, and a venous pressure gauge 11 connected in sequence through an extracorporeal blood pipeline; The meter, heparin pump, degassing system and blood pump are currently commonly used equipment in clinical hemodialysis treatment. The diameter of the core filter cavity is 10cm-5m, and the length of the cavity is 0.5m-5m.

[0015] Before starting the treatment, inject normal saline into the tubing of the device and rinse the inside of the device several times. At this time, the antibody-modified multilayer carbon nanotubes have been placed in the upper cavity of the core filter.

[0016] At the start of trea...

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a circulating tumor cell filtration treatment instrument. The treatment instrument is formed by sequentially connecting an artery pressure meter, a heparin pump, a blood pump, a flow-in pressure meter, a core filtering machine, a degassing system and a vein pressure meter through in-vitro blood pipes. According to the circulating tumor cell filtration treatment instrument, the blood of a patient is guided out through an in-vitro blood circulation system and is connected with the core filtering machine, an carbon nano tube modified by epithelial cell adhesion molecule antibodies is combined with cancer cells, the carbon nano tube combined with the cancer cells is filtered with the semipermeable membrane filtering technology, and finally the filtered blood returns to the body of the patient. By means of the circulating tumor cell filtration treatment instrument, an existing chemoradiotherapy method which causes huge side effects on the patient is replaced, the cancer far end transition probability is effectively reduced, pains of the patient are reduced, and the curing rate of the patient is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a tumor therapy instrument based on physical adsorption. Background technique [0002] Malignant tumors (cancers) are diseases caused by uncontrolled cell division and have become a major killer of people of all ages. According to the 2012 Annual Report of China Cancer Registry, the cancer mortality rate in my country has reached 13%, and it is increasing year by year. However, the treatment of cancer has always been a disease that is difficult to overcome by medicine at this stage. Cancer is a general term for malignant tumors, and tumors include benign tumors (abnormal growth of local cells) and malignant tumors. Localized tumor cells may undergo distant metastasis, in which tumor cells invade the circulatory system (often the blood system) and grow elsewhere in the body. This metastasis is also called "malignant metastasis" and marks the emergence of mali...
