[0031] In this embodiment, for the convenience of observation, the impeller installation sleeve 1 6, the impeller installation sleeve 2 8, the connecting pipe 14 and the reaction tube 15 are all made of transparent materials.

[0032] Before using this device, Fig.14The position shown in the figure, at this time, the sample leakage hole 10 and the sample leakage hole 2 11 are not connected, the titrant leakage hole 1 21 and the titrant leakage hole 2 22 are not connected, and the mixed liquid leakage hole 1 28 and the mixed liquid leakage hole 2 29 are not connected; when it is necessary to test the calcium content in breast milk, firstly, the titrant is added to the reaction tube 15 above the titrant turntable 19 through the titrant inlet pipe 23, and then the buffer and the color developer are added to the reaction tube 15 below the mixed liquid fixed disk 27 through the drug inlet pipe 31; after adding the titrant, the buffer and the color developer, The breast milk sample to be tested fills the sample holding box 9. In the process of filling the sample holding box 9, the sample overflowing from the sample holding box 9 will be blocked by the annular anti-overflow baffle 13 to prevent the overflow device from causing pollution. At this time, slowly press the rubber airbag 2 by hand, the rubber airbag 2 will squeeze the air in the rubber airbag 2, so that the air passes through the air outlet check valve 4 and then drives the rotating impeller 5 to rotate. The rotating impeller 5 will drive the rotating shaft 16 to rotate, and the rotating shaft 16 will drive the pointing rod 17, the titrant turntable 19 and the mixed liquid turntable 26 to rotate. The rotating impeller 1 5 will also squeeze the air to make the impeller 2 7 rotate. When the sample leakage hole 10 and the sample leakage hole 2 11 are overlapped and connected, and the titrant leakage hole 1 21 and the titrant leakage hole 2 22 are overlapped and connected, the rubber airbag 2 is stopped from squeezing. At this time, the impeller 1 5, the impeller 2 7, the pointing rod 17, the titrant turntable 19 and the mixed liquid turntable 26 just rotate 90 degrees. At this time, the mixed liquid leakage hole 1 28 and the mixed liquid leakage hole 2 29 are not connected. At this time, the breast milk sample in the sample holding box 9 and the breast milk sample in the reaction tube 15 above the titrant turntable 19 are The titrant will enter the reaction tube 15 above the mixed solution turntable 26 for mixing; after 30 seconds, continue to squeeze the rubber airbag 2 to make the rotating impeller 15 continue to rotate, and the rotating shaft 16 will drive the titrant turntable 19 and the mixed solution turntable 26 to continue to rotate. When the mixed solution leakage hole 1 28 and the mixed solution leakage hole 2 29 overlap and connect, the mixed solution will enter the reaction tube 15 below the mixed solution fixed disk 27 through the mixed solution leakage hole 2 29, and the mixed solution will be evenly mixed with the buffer and the color developer, and the buffer and the color developer will be completely dissolved by the water in the liquid. After one minute, observe the color of the solution in the reaction tube 15; when the calcium ions in the sample are less than the reference value, all the calcium ions in the sample form complex ions with the complexing agent, and the color developer combined with the calcium ions is freed to make the color bright blue; when the calcium ion concentration is greater than the reference value, the calcium ions and the color developer form a red complex, making the solution color red.

[0033] In this device, when the rubber airbag 2 is squeezed, the air in the rubber airbag 2 first passes through the air outlet check valve 4 and then enters the vent pipe 1. When the rubber airbag 2 is released, the outside air will enter the rubber airbag 2 through the air inlet check valve 3 to replenish the gas under the action of the outside atmospheric pressure; in this way, the rubber airbag 2 can continuously supply air to the vent pipe 1. In the process of the rubber airbag 2 supplying air to the vent pipe 1, the rotating impeller 1 5 will drive the stirring rod 30 to rotate through the rotating shaft 16; after the mixed liquid enters the reaction tube 15 below the mixed liquid fixing plate 27 through the mixed liquid leakage hole 2 29, the rubber airbag 2 can be continuously squeezed and released to make the stirring rod 30 rotate continuously, so that the mixed liquid is evenly mixed with the buffer and the developer.

[0034] After the test results are obtained, the water pipe switch 36 can be turned on to discharge the test liquid in the reaction tube 15. After the test liquid is discharged, water can be added to the reaction tube 15 through the sample holding box 9 and the titrant inlet pipe 23 to repeat the cleaning. The drain hose 37 can discharge the test liquid and cleaning water in the reaction tube 15 without moving the device, which is very convenient.

[0035] By providing the pointing rod 17 and the pointing mark 18, the relative positions of the sample leakage hole 10 and the sample leakage hole 2 11, the titrant leakage hole 1 21 and the titrant leakage hole 2 22, the mixed liquid leakage hole 1 28 and the mixed liquid leakage hole 2 29 can be clearly known; by cooperating with the rotating impeller mounting sleeve 1 6, the rotating impeller mounting sleeve 2 8, the connecting pipe 14 and the reaction tube 15 made of transparent material, the situation in the reaction tube 15 can be known at any time, which is convenient for operation.

[0036] The buffer can be any one of ammonia water, potassium hydroxide, and sodium hydroxide; the color developer can be any one of calcein phenolphthalein indicator, acid chromatin blue K-naphthol green B indicator, acid chromatin dark blue indicator, glyoxal double shrink indicator, calcium carboxylic acid indicator, calcein-methylthyme bromophenol blue-phenolphthalein indicator; the titrant can be any one of ethylenediaminetetraacetate and ethylenediaminetetraacetic acid.
