[0033] With reference to Figure 1 , Figure 2 and Figure 5 , the fixing mechanism 2 comprises a base 201 fixedly connected to the outer wall bottom of the test tube 1, a plurality of fixed blocks 202 are fixedly connected around the base 201, a plurality of support frames 203 are installed on the outer wall of the fixed blocks 202, square holes 204 are equally arranged on the outer wall top of the support frames 203, a fixed plate 205 is fixedly connected to the inner wall of the square holes 204, clamping holes 206 are equally arranged on the inner wall of the fixed plate 205, a gasket 16 is fixedly connected to the bottom of the base 201 at four corners, and a handle 17 is fixedly connected to the outer wall left and right sides of the square holes 204;

[0034] Specifically, the base 201 is connected to the bottom of the test tube 1, supporting the entire device and providing stability. The fixed blocks 202 around the base 201 disperse the support force, increasing stability. The support frames 203 on the outer wall of the fixed blocks 202 provide additional support, making the device more stable.

[0035] With reference to Figure 1 , Figure 2 and Figure 3The inner wall of the base 201 is fixedly connected with the foot pads 19 at equal intervals, the outer wall of the closing plug one 11 is fixedly connected with the sealing rings one 20 at equal intervals, and the outer wall of the push plug 4 is fixedly connected with the sealing rings two 21 at the middle part;

[0036] Specifically, the inner wall of the base 201 is fixedly connected with the foot pads 19 at equal intervals, and the foot pads 19 are uniformly distributed to ensure the stability and supporting force of the base 201. The outer wall of the closing plug one 11 is fixedly connected with the sealing rings one 20 at equal intervals, and the sealing rings one 20 are uniformly distributed on the outer periphery of the closing plug one 11 to ensure that the closing plug one 11 can form a good sealing effect when it is in contact with related components. In addition, the outer wall of the push plug 4 is fixedly connected with the sealing rings two 21 at the middle part, and the sealing rings two 21 are also uniformly distributed on the outer periphery of the push plug 4 to ensure that the leakage of liquid or gas can be effectively prevented during the movement of the push plug 4, and the sealing and stability of the system are maintained.

[0037] Working principle: push plug 4 is located in the fixed hole 3 of the inner wall of the test tube 1 bottom, and is in sliding connection with the inner wall of the fixed hole 3, which makes the push plug 4 can move up and down in the fixed hole 3, change the volume of the inner wall of the test tube 1 and change the storage capacity, the outer wall bottom of the push plug 4 is rotationally connected with the threaded rod 5, and the threaded rod 5 is in threaded connection with the rotating disc 6. When rotating the rotating disc 6, the threaded rod 5 will move along its axial direction due to the action of the thread. Because the threaded rod 5 is rotationally connected with the push plug 4, the axial movement of the threaded rod 5 will drive the push plug 4 to slide up and down in the fixed hole 3. By rotating the rotating disc 6, the position of the push plug 4 can be accurately controlled, so as to realize certain operation in the test tube 1, push the material in the test tube 1 upwards and downwards, the fixed ring one 7 is fixed on the outer wall top of the push plug 4, and the outer wall is connected with the spring one 8. The spring one 8 can play a buffering and resetting role when the push plug 4 moves. When the push plug 4 moves upwards, the spring one 8 will be compressed, and the spring one 8 stores elastic potential energy. When the external force disappears, the elastic potential energy of the spring one 8 is released, and the push plug 4 is pushed to return to the original position. The inner wall of the fixed ring one 7 is equally provided with a circular hole 9, and the circular hole 9 is rotationally connected with a ball 10. The existence of the ball 10 reduces the friction between the push plug 4 and the inner wall of the fixed hole 3 during the movement of the push plug 4, so that the sliding of the push plug 4 is more smooth. The outer wall top of the spring one 8 is in sliding connection with the closing plug one 11, and the closing plug one 11 is used for sealing and separating the bottom of the test tube 1. When the push plug 4 moves, the closing plug one 11 will move with the expansion and contraction of the spring one 8. The closing plug one cooperates with the closing plug two 15 to prevent leakage of the material in the test tube 1 and control the flow of the material. The sealing cover 12 is installed on the outer wall top of the test tube 1, which plays a sealing role of the test tube 1, prevents the leakage of the material in the test tube 1 and prevents the material from being contaminated by the outside world. The inner wall of the sealing cover 12 is fixedly connected with the fixed ring two 13, the inner wall of the fixed ring two 13 is fixedly connected with the spring two 14, and the outer wall bottom of the spring two 14 is fixedly connected with the closing plug two 15. The closing plug two 15 is used for further improving the sealing effect. When the sealing cover 12 is covered on the test tube 1, the spring two 14 will exert a pressure on the closing plug two 15, so that the closing plug two 15 is tightly attached to the inner wall of the test tube 1, and the sealing performance is improved. When the sealing cover 12 is opened, the spring two 14 will return to the original state, and the closing plug two 15 will also move. The volume of the anticoagulant required per milliliter of blood sample is different from the hematocrit. In high altitude areas, due to the reduction of oxygen content in air, the body compensates for the increase of red blood cells with the increase of altitude, and there are more patients with HCT greater than 0.55. The lower the same altitude is, the more patients with HCT less than 0.55. It leads to that the coagulation sample detection personnel and nurses process such samples, the process is complicated and time-consuming, and there is a risk of sample contamination. By calculating the blood collection amount according to the HCT of the patient, adjusting the blood collection amount and re-drawing blood, the nurse can collect blood according to the requirements, which simplifies the operation process, prevents the blood collection tube from being contaminated, saves time, and is more accurate than adjusting the amount of anticoagulant. The blood collection amount is within 0.2mL of the deviation, which does not affect the result.74When the sample is greater than 4.2mL, the total volume of the blood coagulation sample collection tube used in some areas is less than 5mL, when the sample to be collected is greater than 4mL, the risk of blood splashing caused by the cover of test tube 1 falling off and causing contamination exists, and there is a biological safety hazard, especially when HCT is greater than 0.76, the sample to be collected is greater than 4.5mL, the conventional blood coagulation sample collection tube cannot meet the requirements, and only by adjusting the amount of anticoagulant can the blood be collected again. However, the sample collected by adjusting the amount of anticoagulant often has a total sample volume of less than 1mL, and some even less than 0.5mL, which is not enough to detect multiple coagulation items. The blood coagulation sample collection tube with a total capacity of 10mL in the large test tube 1 solves the above problems. The sample collected in the large test tube 1 is sucked into a small cup for detection, which helps to improve the detection quality and improve the work efficiency.

[0038] The base 201 is fixedly connected to the outer wall of the bottom of the test tube 1, mainly plays a supporting role for the whole device, and provides a stable foundation for the whole device. The four perimeters of the base 201 are fixedly connected with the fixed blocks 202, which can disperse the supporting force of the base 201 and increase the stability of the device. The outer walls of the plurality of fixed blocks 202 are installed with the support frames 203, which provide additional support structure for the whole device, making it more stable. The outer wall top of the support frame 203 is equally provided with square holes 204, and the inner wall of the square hole 204 is fixedly connected with the fixed plate 205. The arrangement of the square holes 204 and the fixed plate 205 can provide mounting positions and support points for other components of the device. The inner wall of the fixed plate 205 is equally provided with clamping holes 206, which are used to fix the test tube 1. By inserting the test tube 1 into the clamping hole 206, the fixation and support of the test tube 1 are realized, so as to expand the function of the whole device or perform experimental operation. The equipment, instruments and tools related to the experiment are positioned and fixed through the clamping holes 206, so as to ensure the stability of the test tube 1 during the experiment and the accuracy of the relative position.
