s1, calculating the quality of blood;
firstly, placing an empty test tube for blood collection in the device, and reading the gravity W1 of the empty test tube by a gravity sensor in the device;
then, placing the centrifuged test tube into the device, and reading the gravity W2 of the centrifuged test tube by a gravity sensor;
finally, the two obtained gravity change results Δ W ═ are calculated (W)2-W1) Obtaining the quality of the collected blood
Wherein g is 9.8N/KG.
S2, calculating the volume of the blood;
firstly, according to the density formula
Calculating the volume of blood
Since the relative density of blood with respect to water is 1.05-1.06. The average relative density of 1.055 was selected as the blood density in this example. Thus, the volume of blood is calculated as
S3, calculating the diameter of the test tube;
firstly, the diameter d of the rigid plastic shell is measured by a side wall distance sensor1And the distance L between the rigid plastic shell and the test tube wall1And the diameter calculation result of the outer side wall of the test tube is d2＝d1-2×L1So that the calculation of the inside diameter of the test tube is d3＝d2-2L2Wherein L is2The thickness of the blood sampling test tube is usually 1 mm, and the area of the blood level in the test tube is calculated
S4, calculating the height H of the blood in the test tube;
the height of the collected blood in the test tube is
Because the blood in human body is composed of plasma and blood cells, the volume percentage of the blood cells in the blood is called hematocrit, the hematocrit of a normal adult male is 40% -50%, the hematocrit of a normal adult female is 37% -48%, and the height of the blood cells in a test tube after centrifugation is about equal to that of the blood cells in the test tube after centrifugation

The following describes in detail another embodiment of the method of the present invention for detecting plasma chyle and hemolysis in a multi-size test tube.
Since blood in the human body consists of main plasma and blood cells, the mass of the blood cells is greater than that of the plasma, under the action of centrifugal force. The blood cell layer is arranged at the bottom of the test tube, the blood plasma layer is arranged above the blood cell layer, the respective colors of the blood cell layer and the blood plasma layer are uniformly distributed, but the color of the blood cell layer is obviously different from that of the blood plasma layer. Therefore, the color sensor scans and records the RGB values in the test tube from the bottom of the test tube to obtain RGB value 1, RGB value 2, RGB value 3, RGB value 4, RGB value 5, RGB value 6, RGB value 7 and RGB value 8, respectively.
When the RGB value 1 ≠ RGB value 2 ≠ RGB value 3 ≠ RGB value 4 ≠ RGB value 5 ≠ RGB value 6 ≠ RGB value 7 ≠ RGB value 8, then:
the RGB value 1 is the color value of the test tube lattice;
the RGB values 2, 3 and 4 are the color values of the blood cell layer in the test tube lattice;
the RGB value 5, the RGB value 6 and the RGB value 7 are color values of the plasma layer in the test tube lattice;
the RGB value 8 is the color value of the tube lattice after being inserted into the tube.
Therefore, the RGB value 6 is compared with the RGB values pre-stored in the database, and the database feeds back the chyle index and the degree of hemolysis corresponding to the RGB values.
When the RGB value 1 ═ RGB value 2 ═ RGB value 3 ≠ RGB value 4 ≠ RGB value 5 ≠ RGB value 6 ≠ RGB value 7 ≠ RGB value 8, then:
the RGB value 1, the RGB value 2, the RGB value 3 and the RGB value 4 are color values of the blood cell layer in the test tube lattice;
the RGB value 5, the RGB value 6 and the RGB value 7 are color values of the plasma layer in the test tube lattice;
the RGB value 8 is the color value of the tube lattice after being inserted into the tube.
Therefore, the RGB value 6 is compared with RGB in the database, and the database feeds back the chylomicron index and the degree of hemolysis corresponding to the RGB value.
In addition, the invention can also measure the distance H between the bottom of the rigid plastic shell and the bottom of the test tube through the bottom distance sensor1When the device is just started, the color sensor of this embodiment is disposed at a fixed position on the device, i.e., an initial starting position, and the distance between the initial starting position and the bottom of the rigid plastic shell is H5When H is present5>H1While, the color sensor is lowered H5-H1The distance of (d); when H is present5<H1While, the color sensor rises H1-H5The distance of (d); at this time, the color values of the test tube lattices are recorded, and then RGB values 1, 2, 3, 4, 5, 6, 7 and 8 are obtained.
When the RGB value 1 ═ RGB value 2 ═ RGB value 3 ≠ RGB value 4 ≠ RGB value 5 ≠ RGB value 6 ≠ RGB value 7 ≠ RGB value 8, then:
the RGB value 1, the RGB value 2, the RGB value 3 and the RGB value 4 are color values of the blood cell layer in the test tube lattice;
the RGB value 5, the RGB value 6 and the RGB value 7 are color values of the plasma layer in the test tube lattice;
the RGB value 8 is the color value of the tube lattice after being inserted into the tube.
Therefore, the RGB value 6 is compared with RGB in the database, and the database feeds back the chylomicron index and the degree of hemolysis corresponding to the RGB value.
In summary, the invention has the following advantages:
1. the color sensor can accurately distinguish slight color changes, can objectively observe the chyle degree and the hemolysis degree of the plasma, and particularly can avoid the conditions of non-uniform standard and non-uniform judgment result caused by subjective factors of operators when the collected blood sample has chyle blood and hemolysis simultaneously;
2. the whole test tube lattice is sealed and light-proof, natural light cannot enter the test tube lattice, and meanwhile, a light source required by the color sensor is a yellow light lamp, so that the decomposition of medicines or metabolites in blood plasma under the natural light can be effectively prevented, the detection error is avoided, and the quality of a sample is improved;
3. the motor starts to work according to the control signal of the signal processing system, so that the power wheel is driven to rotate, the height position of the color sensor is adjusted by matching the fixing force wheel and the double chains, blood samples of test tubes of different specifications can be detected, and the motor is wide in application range and high in practicability.
4. According to the invention, the distance between the rigid plastic shell and the test tube is sensed in real time through the side wall distance sensor and the bottom distance sensor, the signal processing system triggers corresponding control signals according to the sensed distance signals to control the work of the modules such as the motor and the display, so that collision between the test tube and the rigid plastic shell due to the close distance can be prevented, and the safety is high.
