ELECTRONIC DETECTION PEN AND EARLY PREGNANCY WEEK NUMBER DETECTION METHOD

摘要

Disclosed in the present invention is an electronic detection pen, comprising a housing, a control circuit, and test paper. The test paper is used for measuring the concentration of the human chorionic gonadotropin in urine, and comprises first test paper and second test paper; the minimum detectable quantity of the human chorionic gonadotropin of the first test paper is less than that of the human chorionic gonadotropin of the second test paper; the control circuit is used for obtaining an early pregnancy week number detection result according to the chromogenic reaction of the first test paper and the chromogenic reaction of the second test paper, and outputting the detection result by means of a liquid crystal display (LCD) connected to the control circuit. By providing the first test paper and the second test paper with different minimum detectable quantities of the human chorionic gonadotropin, the hCG concentration in human urine to be tested can be deduced by means of the reaction comparison of the first test paper and the second test paper, and the hCG concentration in the urine during the early pregnancy period of a pregnant woman is associated with the pregnancy time, so that the early pregnancy week number of the pregnant woman to be tested can be detected.
