Technical Field

[0001] The utility model belongs to the technical field of protein mixing mechanisms, and particularly relates to a preheating and mixing device for procalcitonin detection. Background Art

[0002] Procalcitonin is a protein, and its level in plasma increases when there are severe bacterial, fungal, parasitic infections, as well as sepsis and multiple organ failure. It does not increase in cases of autoimmunity, allergy, and viral infection. Localized limited bacterial infections, mild infections, and chronic inflammation do not cause its increase. Bacterial endotoxin plays a crucial role in the induction process.

[0003] The main method for procalcitonin detection is blood sampling. The specific detection method is as follows: radioimmunoassay. Artificial polyclonal antibodies are used to specifically recognize and bind to synthetic amino acid procalcitonin, and then radioanalysis is carried out. However, during the synthesis process, corresponding mixing and stirring treatments are required. Generally, manual rotation of the stirring rod is used for mixing. However, the long-term stirring process is prone to cause muscle damage, and coupled with the relatively high work intensity of medical staff themselves, it affects the enthusiasm of personnel for work and is not conducive to improving work efficiency. Content of the Utility Model

[0025] Referring to the attached Figures 1-4 As shown in the figure, a preheating and mixing device for procalcitonin detection includes:

[0026] A test tube 1;

[0027] A stirring assembly 2, the stirring assembly 2 includes an upper guide ring 3 and a lower guide ring 4 which are both hollowly arranged. The inner walls of the upper guide ring 3 and the lower guide ring 4 are both movably connected with a pressing rod 5. On the outer wall edges of the pressing rod 5 near one side of the upper guide ring 3 and the lower guide ring 4, an upper bearing 6 and a lower bearing 7 are respectively connected. As the pressing rod 5 moves downward, the upper bearing 6 and the lower bearing 7 drive the stirring rod 8 to rotate; A reset assembly 9, the reset assembly 9 includes a sleeve 10 which is connected to the pressing rod 5 and fixed at the bottom end of the lower guide ring 4. A pushing block 12 fixed on a compression spring 11 is installed on the inner wall of the sleeve 10. As the pressing rod 5 drives the pushing block 12 to move downward, the compression spring 11 rebounds to drive the pressing rod 5 to reset.

[0028] Specifically, the upper bearing 6 and the lower bearing 7 adopt stroke-type linear bearings. The frictional force of the up and down movement of the pressing rod 5 is used to drive the rotational movement of the bearings. Moreover, by the way of pushing the pressing rod 5 downward, the stirring assembly 2 is subjected to a mixing process. Compared with the direct manual rotation method, it can be more labor-saving and achieve the purpose of improving work efficiency.

[0029] A positioning post 13 is fixedly connected to the outer wall of the upper guide ring 3. An internal thread is provided on the inner wall of the positioning post 13, and an adjusting bolt 14 is installed by means of threaded connection. One end of the adjusting bolt 14 is fixedly installed with a contact block 15 placed on the inner wall of the test tube 1. Jacks are provided on the outer walls of the upper bearing 6 and the lower bearing 7, and a stirring rod 8 is installed by means of plug-in fixation. The upper guide ring 3 and the lower guide ring 4 provide corresponding moving spaces for the movement of the pressing rod 5, and can also prevent deviation of the position. Moreover, the upper guide ring 3 and the lower guide ring 4 also provide rotating spaces for the corresponding upper bearing 6 and lower bearing 7 and give corresponding supporting forces.

[0030] Different from the direct manual stirring method, this device can directly rotate the stirring rod 8 by pulling downward. Moreover, during the rotation process of the stirring rod 8, the elastic restoring force of the compression spring 11 can be utilized to automatically drive the rotation of the bearing through friction.

[0031] A chute adapted to it is connected to the outer wall edge of the pressing rod 5 along the height direction of the sleeve 10. The bottom end of the compression spring 11 extends to the center of the bottom end of the inner wall of the test tube 1. Limit plates 16 connected to the pressing rod 5 and the pushing block 12 are provided around the inner wall of the sleeve 10. The setting of the limit plates 16 on the inner wall of the sleeve 10 can play a role in limiting and protecting the movement of the pressing rod 5 and the pushing block 12, thereby preventing them from deviating from the moving track and improving the safety of the device.

[0032] The mixing device can be adaptively clamped and fixed to test tubes 1 of different sizes. By means of threaded rotation, the contact block 15 on the adjusting bolt 14 is attached to and supports the outer wall of the test tube 1, providing a supporting force for the entire device and also preventing the structural members from shaking. In this way, it can also ensure that the device can maintain a vertical state, and the structural members are convenient for installation and disassembly, which is beneficial for personnel operation.
