This embodiment is a structure of a body fluid sample carrier, the specific structure of which is shown in FIGS. 1 to 3.

As shown in fig. 1 and 2, the body fluid sample carrier structure includes a circular chamber cover 20 and a circular slide 10. The circular glass slide 10 is used for bearing the body fluid sample and can be used for sedimentation of cells, so that the cells can be uniformly spread. The glass slide 10 is made of transparent glass material, and the glass material has excellent light transmittance. The cavity cover 20 is made of organic glass. The surface of the glass slide 10 is attached to the bottom surface of the cavity cover 20. The cavity cover 20 is provided with a shroud 25 surrounding the slide 10 toward the outer edge of the bottom surface of the slide 10.

As shown in FIGS. 1 and 2, a circular sample addition port 21 is provided at the center of the chamber cover 20. The sample addition port 21 is a tapered port with a small top and a large bottom. The bottom surface of the chamber cover 20 facing the slide 10 is provided with 6 receiving grooves 22 of different heights evenly distributed around the sample addition port 21. The heights of the 6 accommodation grooves 22 are 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, and 1mm, respectively. The projected areas of all the receiving grooves 22 on the surface of the slide 10 are equal. As shown in fig. 2, all the accommodating grooves 22 and the surface of the slide 10 respectively enclose chambers 220 for accommodating the body fluid to be detected at different heights, so that the chambers 220 have different volumes from each other and can be used for detecting and analyzing different types of cells. The sample addition port 21 is in equidistant communication with all the chambers 220. Specifically, as shown in FIG. 2, all chambers 220 are communicated with one annular channel 210 and surround the annular channel 210, and the sample injection port 21 is arranged in the middle of the annular channel 210, and the sample injection port 21 is communicated with all chambers 220 at equal intervals through the annular channel 210.

In other embodiments, other numbers of chambers greater than 1 may be provided.

As shown in fig. 1 and 2, the cavity cover 20 is provided with a liquid outlet 23 outside the housing groove 22, and the liquid outlets 23 are all communicated with the chamber 220. The drain port 23 serves to drain excess bodily fluid sample, equalizing the pressure of the fluid in the chamber 220. The opening of the drain port 23 is parallel to the opening of the sample addition port 21. As shown in fig. 2 and 3, the outer edge of the upper surface of the cavity cover 20 is provided with a liquid discharge ring groove 26, and all the liquid discharge ports 23 are communicated with the liquid discharge ring groove 26.

As shown in fig. 1, the area between adjacent receiving channels 22 is an adhesive area 24 for secure attachment to the slide 10. The adhesive region 24 is fixedly attached to the slide 10 by adhesive or double-sided tape.

Before body fluid measurement, a body fluid sample with a certain proportion is uniformly mixed, and then the body fluid sample is stably injected through the sample injection port 21 by a liquid transfer device. The body fluid sample will fill each chamber 220 rapidly under gravity and capillary force, and the excess body fluid sample will overflow from the liquid outlet 23 to the liquid discharge ring groove 26 until the liquid level is balanced. After settling, the cells of the body fluid will settle uniformly on the base surface of the slide 10, and subsequent measurement can be performed from bottom to top through the objective lens 30, as shown in fig. 4.

In this embodiment, the accommodating grooves 22 with different heights but the same projection areas on the cavity cover 20 and the glass slide 10 form the chambers 220 with different heights, so that the body fluid sample can be rapidly filled into each chamber 220 under the capillary force after being injected from the sample injection port 21, and the chambers 220 with different heights are used for detecting different types of cells, so that the body fluid can be detected by only once loading the body fluid onto the sample carrier, the steps are simplified, and the detection efficiency is improved.
