The invention discloses a microfluidic multifunctional seminal fluid analysis device, which comprises an upper shell, a detection chip cover plate, a detection chip bottom plate and a lower shell, wherein the detection chip cover plate and the detection chip bottom plate are stacked to form a microfluidic seminal fluid detection chip, and the upper shell, the microfluidic seminal fluid detection chip and the lower shell are sequentially stacked and combined to form an integral analysis device; the upper shell is provided with a sperm counting observation window and a pH detection window; a light source entering window is arranged at the position, corresponding to the sperm counting observation window, of the lower shell, a sperm counting pool is arranged at the position, corresponding to the sperm counting observation window, in the microfluidic seminal fluid detection chip, a pH detection pool is arranged at the position, corresponding to the pH detection window, in the microfluidic seminal fluid detection chip, and pH test paper is placed in the pH detection pool. The device is simple in structure, easy to manufacture and convenient to use, not only can be used for clinical medical sperm examination, but also can be matched with a household sperm instrument on the market to enter a family for use, and embarrassment of hospital sampling can be reduced to a great extent.
Description
technical field [0001] The invention relates to the technical field of novel medical detection, in particular to a microfluidic multifunctional semen analysis device. Background technique [0002] In recent years, the worldwide infertility rate has reached 15%, becoming the third major disease after cancer and cardiovascular and cerebrovascular diseases. There are about 60-80 million infertile couples in the world, and at least 10 million infertile couples in China, and infertility caused by male sperm quality problems in couples of childbearing age accounts for almost 50% of the total cases. Infertility will not only affect the work and life of the patient, but also cause family breakdown, social disharmony, and a decline in the quality of the birth population. Semen analysis is the standard for judging male fertility. At present, the commonly used test method for sperm quality in clinical cases is computer-aided sperm analysis (CASA). During the detection process, actual...
