[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. For example... Figures 1-6 As shown, the blood testing machine of the present invention includes a feeding device 1, a picking device 2, and a dispensing device 3 arranged sequentially from front to back on the front frame 6, and a transfer device 4 and a testing device 5 on the rear frame 8. After blood sample collection, the blood collection tube and other materials are placed into the feeding device 1. After the feeding device 1 feeds the materials, the picking device 2 picks up the blood collection tube and other materials from the feeding device 1 and moves them to a set position in the dispensing device 3. The blood in the blood collection tube is sampled by the dispensing device 3 and the reagents required for testing are added to form the test sample. The transfer device 4 moves the test sample to the testing device 5 for blood testing.

[0021] In the above technical solutions: such as Figure 3 As shown, the testing device 5 includes a testing base plate 51, on which a testing positioning plate 53 is fixed by a screw jack 52. A thromboelastography instrument 54 is mounted on the testing positioning plate 53. The internal structure of the thromboelastography instrument 54 is prior art, including components such as circuit boards. The thromboelastography instrument 54 is used to monitor and analyze the coagulation state of blood samples to determine whether they have normal coagulation function. The thromboelastography instrument 54 is equipped with a test head 542 and a testing seat 541. Testing connecting rods 543 pass through both sides of the testing seat 541. The tops of the testing connecting rods 543 are mounted on the thromboelastography instrument 54. The testing seat 541 can move up and down along the testing connecting rods 543 on both sides. The testing seat 541 is located directly below the test head 542. The test head 542 includes a test shaft 5421 and a test rod 5422, with the test shaft 5421 protruding from the bottom of the test head 542. The test head 542 has a switch groove 5423, and one end of the test rod 5422 passes through the switch groove 5423. The switch groove 5423 includes a vertical groove and a horizontal groove perpendicular to the vertical groove. Figure 3 The test rod 5422 shown is located at the junction of the vertical and horizontal grooves and is in the off state. The bottom end of the vertical groove is the unloading end, and the right end of the horizontal groove is the detection end. The inspection seat 541 has a test cup inspection groove 5411 for placing the test cup. The bottom of the inspection seat 541 has a button 5412. Pressing the button 5412 causes the test cup to be ejected and removed from the test cup inspection groove 5411.

[0022] In the above technical solution: the measuring cup includes a cup body 71 and a cup lid. For example... Figure 5 As shown, the cup body 71 has a hollow structure, and a retaining rim 711 extends outward from the mouth of the cup body 71. An inclined guide slope 712 is formed at the opening of the inner wall of the cup body 71. Figure 6 As shown, the cup lid includes a cover plate 721 and a fixing post 722 located at the center of the cover plate 721. The lower part of the fixing post 722 protrudes outward and forms an inclined cup lid step 7221 with the upper part. A cup lid groove 723 is formed in the center of the cover plate 721. The test shaft 5421 and the cup lid groove 723 are fitted together. The groove wall of the cup lid groove 723 is provided with a fitting rib.

[0023] In the above technical solution: two lever mechanisms 55 are also installed on the inspection positioning plate 53, and the lever mechanisms 55 are located below the inspection seat 541. Figure 4 As shown, the block-moving mechanism 55 includes a block-moving base plate 551. A sliding groove 5511 is formed in the middle of the block-moving base plate 551. The groove openings on both sides of the sliding groove 5511 form block-moving guard edges 5512. A block is provided within the sliding groove 5511. The block includes a top block-moving rod 5521, a bottom block-moving seat 5522, and a trapezoidal block 5523 located between the block-moving rod 5521 and the block-moving seat 5522. A block-moving step is formed between the edge of the block-moving seat 5522 and the trapezoidal block 5523. The block-moving seat 5522 is located within the sliding groove 5511 and can move within it. The block-moving guard edges 5512 are located on the block-moving step. The thromboelastography instrument 54 has two block-moving holes. The top of the block-moving rod 5521 passes through the block-moving hole and has a block-moving groove 55211 on it.

[0024] The inspection device 5 is responsible for separating the empty test cup body 71 from the cup lid and for inspecting the processed blood sample. When separating an empty test cup, the material handling device 2 picks up the empty test cup from the test cup feeding conveyor line and moves it into the material dispensing device 3. The material transfer device 4 picks up the empty test cup and moves it into the test cup inspection slot 5411 of the inspection device 5. The material transfer device 4 then moves to below the inspection seat 541 and moves the inspection seat 541 and the empty test cup inside it upwards until the cup lid is in close contact with the bottom of the test head 542. At this point, the test shaft 5421 is located in the cup lid slot 723. Next, the material transfer device 4 moves to below the button 5412 and moves upwards to press the button 5412 at the bottom of the inspection seat 541, causing the mating rib in the cup lid slot 723 and the test shaft 5421 to have an interference fit. The transfer device 4 then moves above the inspection seat 541, causing the inspection seat 541 to move downwards. At this time, the cup lid is left at the bottom of the test head 542, achieving separation of the cup lid and the cup body 71. The transfer device 4 continues to move downwards until the button 5412 is pressed by the top of the lever 5521. The button 5412 ejects the empty cup body 71 from the test cup inspection slot 5411. The transfer device 4 picks up the empty cup body 71 and moves it into the dispensing device 3 to await sample addition.

[0025] During testing, the transfer device 4 first moves the lever, positioning the lever groove 55211 directly below the button 5412. The transfer device 4 then picks up the sample-loaded cup 71 and moves it into the testing cup groove 5411 of the testing device 5, pressing down on the edge of the cup 71 to ensure it is completely within the testing cup groove 5411. During this process, the testing seat 541 and the button 5412 at its bottom also experience downward displacement. The lever groove 55211 prevents the button 5412 from contacting the lever 5521 during its downward movement, which would cause the button 5412 to be squeezed and eject the sample-loaded cup 71 from the testing cup groove 5411, resulting in liquid spillage, sample damage, and rendering the sample unusable for testing. Next, the transfer device 4 moves to below the inspection seat 541 and moves the inspection seat 541 upward until the upper surface of the inspection seat 541 is in close contact with the bottom of the test head 542. The transfer device 4 moves the test rod 5422 to the detection end, and the test begins. The thromboelastography instrument 54 analyzes the sample. After the analysis is completed, the transfer device 4 moves the test rod 5422 to the off state and presses it down to move it to the unloading end, causing the cup cover to detach from the test shaft 5421 and fall onto the cup body 71. The transfer device 4 moves the lever, causing the lever slot 55211 to move away from directly below the button 5412. The transfer device 4 moves the inspection seat 541 downward until the button 5412 is pressed by the top of the lever 5521. The button 5412 ejects the test cup from the test cup inspection slot 5411, completing the test.

[0026] The working process of the blood testing machine is as follows: The feeding device 1 begins feeding materials. The picking device 2 picks up each material and moves it to the corresponding position in the mixing device 3. The blood collection tube is also picked up by the picking device 2 and moved into the mixing device 3. The picking device 2 also moves the blood collection tube and other materials within the mixing device 3. The blood in the blood collection tube is sampled by the mixing device 3, and the necessary reagents are added to form the test sample. During this process, the transfer device 4 picks up the empty test cup and moves it into the testing device 5, completing the separation of the cup lid and cup body 71. Next, the transfer device 4 picks up the empty cup body 71 and moves it into the mixing device 3, where the testing device 3 transfers the test sample into the cup body 71. Finally, the sample is tested. The transfer device 4 picks up the sample-filled cup body 71 and moves it into the testing device 5 for blood testing, completing one testing cycle.
