If the body fluids need to be divided into multiple portions and transported to different locations for testing, the body fluids in the bottle need to be poured into multiple containers. This method can easily cause body fluid spillage. After transporting to the designated laboratory, the bottle lid needs to be opened before the body fluids can be extracted. This process can easily cause the body fluids to be contaminated by the external environment, resulting in inaccurate test results. Summary of the invention

[0027] When sampling, the liquid storage frame 29 filled with body fluid is placed on the desktop, the liquid extraction structure is lowered from the top of the liquid storage frame 29, and the pressing block 5 is pressed so that the pressing block 5 drives the first rubber plug 4 to move downward through the push rod 3. At this time, the gas inside the first chute 2 is discharged through the liquid outlet structure. When the first rubber plug 4 drops to the bottom of the first chute 2, the pressing block 5 is released. Under the action of the first compression spring 6, the pressing block 5 drives the first rubber plug 4 to rise through the push rod 3. At this time, negative pressure is formed inside the first chute 2, and the third rubber plug 17 blocks the second cavity 15. The body fluid in the liquid storage frame 29 passes through the conduit 22 and pushes the second rubber plug 11 upward.

The body fluid in the first slide groove 2 passes through the connecting hole 7 to push the third rubber plug 17 to move away from the center of the first slide groove 2. The third rubber plug 17 no longer blocks the second cavity 15 and the second rectangular groove 19. The body fluid passes through the second cavity 15 and the second rectangular groove 19 through the transfer tube 20, and then passes through the transfer tube 20 and the liquid passage groove 21 through the third cavity 2804 and the third rectangular groove 2808 into the liquid passage tube 2809. The liquid flows out from the bottom of the liquid passage 2809 into the middle of the groove 2811 and pushes the fourth rubber plug 2806 to move upward. At this time, the gas in the middle of the liquid storage chamber 2802 and on the upper side of the fourth rubber plug 2806 is discharged through the air outlet 2812. When the fourth rubber plug 2806 moves to the top of the liquid storage chamber 2802, the liquid storage chamber 2802 is filled with body fluid, and the liquid storage device 28 is taken out from the middle of the adjustment structure. Under the action of the fourth compression spring 2807, the fourth rubber plug 2806 blocks the third cavity 2804 and the third rectangular groove 2808 again, and the body fluid is sealed in the liquid storage device 28; The liquid storage device 28 containing the body fluid is transported to a designated laboratory, and a needle is inserted into the air outlet 2812 and pierces the fourth rubber plug 2806, and the body fluid in the liquid storage cavity 2802 is extracted through the needle for subsequent testing. The body fluid can be loaded into multiple liquid storage devices 28 at one time through the liquid extraction structure, reducing the workload of body fluid subpackaging and the risk of body fluid spillage, and the fifth rubber plug 2810 encapsulates the body fluid in the liquid storage device 28, and it is not easy to contaminate the sample when the body fluid in the liquid storage device 28 is taken out, thereby improving the accuracy of the test results.
