Multifunctional portable body fluid detection device

The invention relates to a multifunctional portable body fluid detection device which is composed of a cover glass and a glass slide, a liquid sample filling chamber is formed between the cover glass and the glass slide, and a slidable wedge is arranged between the cover glass and the glass slide. An inclined surface corresponding to the wedge-shaped surface of the wedge block is arranged on one of the lower surface of the cover glass and the upper surface of the glass slide; the cover glass is movable relative to the glass slide. The different corresponding positions of the wedge-shaped face and the inclined face enable the liquid label piece filling chamber to have the adjustable height capable of adapting to inflow of liquid with different liquid tension. According to the invention, the gap between the cover glass and the glass slide can be adjusted, so that liquid with different liquid tensions can smoothly flow into the space between the cover glass and the glass slide. Therefore, the device has the func
