[0027] Please refer to Figures 1-8 , a cap-off centrifuge for blood collection tube, comprising a centrifuge body 1, a mounting shaft 2 is rotatably arranged in the centrifuge body 1, a detachable rotating frame 3 is mounted on the mounting shaft 2, a plurality of mounting grooves 4 are arranged in the detachable rotating frame 3 in a ring shape, a basket 5 is mounted in the mounting grooves 4, a plurality of test tube receptacles 7 are arranged in the basket 5 in an interval, for placing blood collection tubes, a cap-off plate 6 is provided with a plurality of holes corresponding to the test tube receptacles 7, and further comprising:

[0028] A cap-off assembly is arranged in the basket 5, for cap-off of the blood collection tube;

[0029] An elastic supporting assembly is arranged in the basket 5, for elastic supporting of the blood collection tube;

[0030] A cover plate assembly is disposed in the mounting groove 4 for sealing the top of the suspended platform 5;

[0031] A clamping assembly is disposed inside the basket 5 and is used to clamp and fix the blood collection tube inserted into the test tube insertion hole 7.

[0032] During use, the blood collection tube is placed in the test tube insertion hole 7 of the basket 5. Under the action of the cover plate assembly and in conjunction with the elastic support assembly, the test tube cap at the top of the blood collection tube is squeezed to prevent the test tube cap from falling off during centrifugation and causing blood to flow out of the blood collection tube. In addition, the clamping assembly can clamp and fix blood collection tubes of different diameters placed in the test tube insertion hole 7 to prevent the blood collection tube from colliding with the inner wall of the test tube insertion hole 7 during centrifugation and causing damage and leakage. After the centrifugation operation of the blood collection tube is completed, the cover plate assembly is opened, and the test tube cap of the blood collection tube can be removed in a centralized manner by the cap removal assembly.

[0033] The cap removal assembly includes a hydraulic rod 29 and a cap removal plate 6. The cap removal plate 6 is slidably connected to the inner wall of the basket 5, and the hydraulic rod 29 is disposed inside the basket 5 and connected to the cap removal plate 6. The cap removal plate 6 has a hole corresponding to the test tube insertion hole 7.

[0034] After the centrifugation of the blood collection tube is completed, the cover assembly opens. At this time, the clamping assembly still clamps the blood collection tube. The controller starts the hydraulic rod 29, which pushes the cap removal plate 6 to rise. The rise of the cap removal plate 6 will pull the test tube cap, thereby separating the test tube cap from the blood collection tube and realizing the cap removal process.

[0035] The elastic support assembly includes an inner cavity 8 opened at the bottom of the basket 5, a support plate 10 is slidably disposed in the inner cavity 8, and a support block 11 corresponding to the test tube insertion hole 7 is installed on the support plate 10. The support plate 10 is connected to the bottom wall of the inner cavity 8 by a first spring 9.

In the process of rotating the cover plate 13, the clamping rod 16 on the extension rod 15 at the end of the cover plate 13 will be in contact with the positioning block 20 and slide along the arc slope surface of the positioning block 20, so that the extension rod 15 is driven to move and the second spring 19 is pressed through the sliding plate 18, and when the clamping rod 16 slides to the position of the clamping groove 21, the clamping rod 16 is clamped into the clamping groove 21 under the action of the second spring 19, so that the connection of the cover plate 13 and the hanging basket 5 is completed.

[0038] When the blood collection tube is completely put into the test tube insertion hole 7 and the bottom of the blood collection tube is placed on the supporting block 11, the cover plate 13 is rotated, so that the rubber pressing plate on the cover plate 13 presses the test tube cap of the blood collection tube downward, and the connection of the cover plate 13 and the hanging basket 5 is completed through the connecting piece, and in the process of moving the blood collection tube downward, the first spring 9 is pressed through the supporting plate 10, and the pressure on the test tube cap of the blood collection tube is applied through the elastic force of the first spring 9, so that the test tube cap is prevented from falling off in the centrifugal process to cause the blood in the blood collection tube to flow out.

[0039] The clamping assembly comprises a bidirectional screw rod 22 rotatably arranged in the hanging basket 5, and a moving frame 23 slidably connected with the inner wall of the hanging basket 5 is threadedly connected to the two sides of the bidirectional screw rod 22, a plurality of installation plates 24 are arranged at intervals and are arranged on the two moving frames 23, the installation plates 24 on the two moving frames 23 are arranged in a staggered manner, a plurality of supports 25 are arranged at intervals and penetrate the test tube insertion hole 7, and a left clamping plate 26 and a right clamping plate 27 are arranged at the ends of the two supports 25 in the test tube insertion hole 7.

[0040] When the blood collection tube is inserted into the test tube insertion hole 7 and the cover plate assembly is closed, the rotating block 28 is rotated, so that the bidirectional screw rod 22 is rotated, the two moving frames 23 are driven to move close to each other, the two installation plates 24 are moved close to each other, the two supports 25 on the two installation plates 24 are moved close to each other, and the left clamping plate 26 and the right clamping plate 27 on the supports 25 are moved close to each other, so that the blood collection tube inserted into the test tube insertion hole 7 is clamped and fixed, and the blood collection tube is prevented from colliding with the inner wall of the test tube insertion hole 7 in the centrifugal process to cause damage and leakage.
