Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment, further illustrate the present invention.

[0017] refer to image 3 , the tumor cell remover in circulating blood of the present invention, it comprises and is connected with in sequence: input conduit 1, medical peristaltic pump 2, tumor cell remover 3 and output conduit 4. in:

[0018] 1. The input catheter 1 and the output catheter 4 are used to connect the veins of tumor patients.

[0019] 2. Medical peristaltic pump 2 uses a medical infusion pump to drive blood flow and circulate blood outside the body.

[0020] The patient's venous blood flows into the infusion tube→medical infusion pump→tumor cell scavenger→reinfused back into the patient's vein.

[0021] 3. Tumor cell remover 3 (one-time use), its structure is: cylindrical outer tube 31 built-in polystyrene fiber filament 32, filter screen 33 is set at the outlet of outer tube 31; polystyrene fiber filament 32 is coated antibodies, such as figu...

Abstract

The invention provides an instrument for removing tumor cells in circulating blood. The therapeutic instrument, which is communicated with the in-vivo circulating blood, effectively removes the tumor cells in the blood by utilizing antibody and performs in-vitro immunity treatment to block the route of the hematogenous spread of malignant tumor. The invention adopts a technical scheme that: the instrument for removing the tumor cells in the circulating blood comprises an input catheter, a medicinal peristaltic pump, a tumor cell remover and an output catheter, wherein the input catheter, the medicinal peristaltic pump, the tumor cell remover and the output catheter are connected with one another sequentially; and the input catheter and the output catheter are connected with the blood vessel of a human body or an animal. The tumor cell remover has the following structure that: a cylindrical outer tube is provided with polystyrene cellosilk inside; a filter screen is arranged at the outlet of the outer tube; and the antibody is coated by the polystyrene cellosilk. The instrument for removing the tumor cells in the circulating blood has the advantages of safe, accurate, timely, continuous and effective removal of the tumor cells, synchronization therapy, obvious improvement of the symptom of a patient, no damage to normal blood cells of the patient in a continuous therapeutic process, low manufacturing cost, simple and convenient operation, practicability and economy, and capacity of relieving the pain of a tumor patient and reducing the burden of the therapy for the patient.

Description

technical field [0001] The invention relates to a medical instrument for clinical treatment of tumors, in particular to a tumor cell remover in circulating blood, which is used for removing disseminated tumor cells in the circulating blood of malignant tumor patients. Background technique [0002] Regardless of whether in China or other parts of the world, malignant tumors have become one of the major lethal diseases. At present, the number of cancer deaths in China is as high as 1.4 to 1.5 million every year. Complications of malignant tumors and their treatments (such as surgery, radiotherapy, and chemotherapy) are the main cause of death for patients, mainly manifested as severe suppression of the immune system, immunodeficiency, severe infections (septicemia, sepsis), metabolic disorders (negative nitrogen Balance, endogenous poisoning), hematopoietic dysfunction, cardiovascular system (hemodynamics, rheology, microcirculation, etc.) disorder, intestinal dysfunction, etc...
