Biochip information reading device and information analyzing method

Abstract

The invention relates to a biochip information reading device and an information analyzing method, discloses a biochip information reading instrument and belongs to the technical field of clinical diagnosis instruments. The traditional 'gold standard' for diagnosing the flora-imbalanced bacterial vaginitis is difficult in actual operation, and is also rough and complicated to operate although certain new technologies are adopted. According to the biochip information reading instrument, a liquid crystal display is arranged on a casing; a mainboard is arranged in the casing below the display; a photoelectric signal processing and data storing chip, a circuit system, a light source and a photoelectric sensor are fixedly arranged on the mainboard; a biochip detecting channel passing from the instrument in the front-back direction is arranged below the mainboard; and a cutter-shaped telescopic clamping tongue is respectively arranged at two sides of a position below the photoelectric sensor in the biochip detecting channel. A mechanical transmission component and a motor are not arranged in the biochip information reading instrument, so that the biochip information reading instrument is small in volume. The biochip information reading instrument can be used for rapidly obtaining multi-index comprehensive judgment results, thereby being comprehensive, accurate and convenient. Thus, the biochip information reading instrument is suitable for the bedside operation by outpatient service doctors in hospitals or the household use by patients.

Description

Technical field [0001] The invention relates to a biological chip information reading device, in particular to a vaginal microecological environment sensor chip information reading device, which belongs to the technical field of clinical diagnostic instruments. Background technique [0002] In women of normal childbearing age, under the action of estrogen secreted by the ovaries, the cervical and vaginal squamous epithelial cells absorb glycogen and gradually mature. After shedding, the intracellular glycogen is released, which is beneficial to the growth of lactobacilli and reduces the pH value in the vagina. The growth of other pathogenic bacteria is inhibited, a normal ecological balance is formed in the vagina, and the secretion of the cervical glands forms a specific micro-ecological environment that resists the invasion of pathogenic microorganisms and maintains a healthy state. When human estrogen levels drop, excessive use of antibiotics, excessive vaginal flushing with a...

Problems solved by technology

[0007] In clinical practice, the Amsel standard has the following deficiencies: 1. It is inconvenient to measure the pH value, 2. The judgment of vaginal secretions is highly subjective, 3. The compliance and objectivity of the sniff test staff are poor, 4. Clue cells are indirect evidence; The Nugent standard also requires smears, Gram staining, and identification, counting, and integration of individual bacterial species under an oil immersion microscope, which requires strong professional experience, is tedious, and time-consuming

[0008] With the continuous in-depth understanding of the pathogenesis of BV, diagnostic methods based on the detection of metabolites of microorganisms unique to the vaginal secretions of BV patients have emerged, and some commercial kits have emerged. For example, the publication number of the China Intellectual Property Office is CN201247244 "Gynecological Multi-item Dry Chemistry Joint Detection Test Strip" and "A Bacterial Vaginosis Rapid Detection Device, Detection Test Strip and Detection Method" with the publication number CN101975852A, these methods are more objective than the above methods and suitable for batch operation , but it is still necessary to judge the color change with the naked eye. It is necessary to use a test to collect vaginal secretions, elute and dilute them, and then add them dropwise to reaction dishes or test strips for color development. The pH value measurement requires direct contact with secretions for color development. , while other reactions are diluted by elution and cannot be operated in the same way. At the same time, the detection after dilution is relatively indirect, which will also reduce the sensitivity, and the operation steps are many and the accuracy is poor.
