Body fluid cancer marker detection device for human body

Abstract

The invention relates to a body fluid cancer marker detection device for a human body. The problems that the conventional detection device is high in manufacturing cost, extremely large in size, complicated in detection, inaccurate in detection result and the like are solved. The body fluid cancer marker detection device comprises magnetic elastic biological test paper, a micro controller, a coil bracket, an enhanced impedance converter, a power circuit, a direct current biasing circuit, a key and a liquid crystal screen, wherein a direct current biasing coil and an alternating current excitation coil are wound on the coil bracket; the magnetic elastic biological test paper is inserted into the coil bracket; a magnetostrictive material thin sheet is arranged on the magnetic elastic biological test paper; an antibody corresponding to a cancer marker to be detected is modified on the magnetostrictive material thin sheet. The magnetostrictive material in the body fluid cancer marker detection device is low in cost, high in sensitivity and high in detection precision; the number of the cancer markers in body fluid can be quickly and accurately detected, and the trouble and the error which are caused by repeated use can be avoided. Furthermore, the body fluid cancer marker detection device is small in size and convenient for portable detection; the noise interference is reduced, and the accuracy and the reliability of detection of the magnetic elastic biological test paper are improved.

Description

technical field [0001] The invention relates to the interdisciplinary field of biomedical engineering and electronic sensing technology, in particular to a human body fluid cancer marker detection device. Background technique [0002] The methods of cancer diagnosis mainly include imaging, pathology, immunology and molecular biology. Among the above-mentioned detection methods, imaging methods such as X-ray, CT or MRI have some shortcomings: first, the detection equipment is expensive, and general hospitals cannot afford the cost of purchasing equipment, resulting in higher fees for patient detection; The reason is that the detection equipment is bulky, and the operation of the equipment is complicated and requires professionals to operate. Therefore, the detection process is relatively cumbersome. Patients need to go to a large hospital for detection by themselves. Often, when the patient feels unwell and goes to the hospital for detection, the cancer has developed to the m...

Among the above-mentioned detection methods, imaging methods such as X-ray, CT or MRI have some shortcomings: first, the detection equipment is expensive, and general hospitals cannot afford the cost of purchasing equipment, resulting in higher fees for patient detection; The reason is that the detection equipment is bulky, and the operation of the equipment is complicated and requires professionals to operate. Therefore, the detection process is relatively cumbersome. Patients need to go to a large hospital for detection by themselves. Often, when the patient feels unwell and goes to the hospital for detection, the cancer has developed to the middle or late stage. The treatment is not timely; the third is that the detection cycle is long, and the test results often take 1 to 2 days; the fourth is that the above detection methods are harmful, and repeated use will cause irreversible harm to human tissues and the surrounding environment

Its disadvantages are: the piezoelectric sensor chip probe is susceptible to the influence of antibody-magnetic microspheres, the number of antibody-magnetic microspheres on the probe and individual differences affect the change of the quality of the adsorbed substance on the probe, resulting in errors in the detection results hard to control
