Problems solved by technology

However, there are indeed many problems in the application of clinical diagnosis and treatment, especially in the POCT (point-of-care testing) technology developed in recent years: ① Special personnel are required to manually operate the whole process of the experiment, and automation is being implemented in various scientific fields today. We are also trying our best to improve efficiency and reduce personnel. It is necessary to use automated instruments instead of manual operations as much as possible, especially the obstetric POCT detection method.
In obstetric outpatient clinics, FFN testing, an indicator used to assess the risk of premature birth for pregnant women, needs to get test results quickly so that pregnant women can be given timely diagnosis and treatment plans. However, in outpatient clinics, there is no dedicated person to operate such a test, and doctors cannot spend 10 minutes alone. There is no time to do such a test, so after sampling, the pregnant woman is required to send the sampling tube to the delivery room of the inpatient department for testing, and then take the test result back to the doctor. Running back and forth between inpatient departments, once an accident occurs, it may cause doctor-patient disputes
Therefore, it seriously affects the convenience for doctors to carry out this test, but FFN is an important indicator recommended by the Chinese Ministry of Health for the management of premature delivery in pregnant women; ②The detection sensitivity is not high, which greatly limits the clinical application of this technology Further applications at work
At present, the colloidal gold detection method mainly interprets the results by naked eyes, and the detection sensitivity is improved through supporting instruments, and the technology for semi-quantitative detection is not widely used.

Abstract

The invention belongs to the field of medical equipment, relates to a test paper detector, and especially relates to a colloidal gold test paper detector. The colloidal gold test paper detector comprises a test tube adapter, an oscillation blending apparatus, a test paper clamping device, a light source, an image information acquisition apparatus, an image processing system and a power source. The colloidal gold test paper detector has the beneficial effects that tedious sample sending, uniform mixing, detection, detection result reading processes are completely automated; the detection sensitivity is increased, the detection of micro-samples and trace quantity samples is realized, a system can improve the condition that evaluation work is carried out by naked eyes, the the difference due to artificial factor subjective determination can be avoided, the staff workload is reduced, and the work efficiency is increased.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a test paper detector, in particular to a colloidal gold test paper detector. Background technique [0002] Colloidal gold immunochromatography is a widely used rapid detection method for detecting pathogens or specific proteins in some clinical samples. This method only needs one step of sample addition, and the result can be determined within 5-10 minutes. Compared with other technologies , has the advantages of simplicity, high efficiency, convenient portability, stable reagents, and low false positive rate, and can effectively solve the difficulties faced in practice. However, there are indeed many problems in the application of clinical diagnosis and treatment, especially the POCT (point-of-care testing) technology developed in recent years: ① Special personnel are required to manually operate the whole process of the experiment, and automation is being implemented in various ...
