Description

Technical Field

[0001] This utility model relates to the field of human fibrinogen production technology, specifically to a centrifuge for human fibrinogen production. Background Technology

[0002] Centrifuges are primarily used for separation and purification in the production of human fibrinogen. Through high-speed rotation, centrifugal force separates different components in a mixture according to their density, size, and other characteristics. Fibrinogen is present in plasma, a complex mixture containing various proteins, electrolytes, and other components. The centrifugal force generated by high-speed rotation allows for the separation of different plasma components based on their physical properties, such as density, size, and sedimentation coefficient. Due to its specific physical properties, fibrinogen separates from other plasma components during centrifugation, facilitating subsequent extraction and purification.

[0003] Existing devices have some drawbacks in use. For example, current medical centrifuges require two different centrifuges to separate different biological samples: one for placing test tubes at an angle and the other for placing them at a vertical angle. However, existing centrifuges can only be placed in one position at a time, so the laboratory needs to purchase two devices, which increases costs and is also more cumbersome to use. Utility Model Content

[0004] The purpose of this invention is to provide a centrifuge for the production of human fibrinogen, which solves the problem that current medical centrifuges require two different centrifuge configurations for separating different biological samples: one for placing test tubes at an angle and the other for placing them at a vertical angle. Existing centrifuges can only be used for single-position centrifugation, so the laboratory needs to purchase two machines, which increases costs and is also more cumbersome to use.

[0005] This utility model provides the following technical solution: a centrifuge for producing human fibrinogen, comprising a shell, a top cover hinged to one side of the shell, a circular partition fixedly connected to the inner side of the shell, a drive motor fixedly installed on the bottom inner wall of the shell, a drive rod fixedly connected to the output end of the drive motor, the top of the drive rod vertically upward through the circular partition and a support plate fixedly sleeved on the top outer wall, a connecting block sleeved on the outer wall of the drive rod, the connecting block being positioned above the support plate, a nut for fixing the connecting block being threaded onto the top of the drive rod, and multiple placement components for placing centrifuge tubes fixedly arranged in a ring array on the outer wall of the connecting block.

[0006] As a preferred embodiment of the above technical solution, the placement assembly includes support plates symmetrically fixedly connected to the outer wall of the connecting block, an adjusting rod rotatably connected between the two support plates, load plates fixedly connected to the outer walls on opposite sides of the adjusting rod, and multiple placement cylinders for inserting centrifuge tubes fixedly arranged on the load plates, with one end of the adjusting rod passing through one of the support plates and the end provided with a snap-fit ​​fixing assembly.

[0007] As a preferred embodiment of the above technical solution, the snap-fit ​​fixing assembly includes a positioning turntable fixedly sleeved on the outer wall of the adjusting rod. The positioning turntable has positioning holes arranged in a ring array, and the side wall of the support plate near the positioning turntable has multiple threaded holes arranged in a ring array. A positioning rod is inserted into the threaded holes and the positioning holes, and the assembly end of the positioning rod is threadedly connected to the threaded hole.

[0008] As a preferred embodiment of the above technical solution, a control panel is embedded on the outer wall of the outer casing of the machine body, and the drive motor is electrically connected to the control panel.

[0009] As a preferred embodiment of the above technical solution, the drive rod and the circular partition are rotatably connected by a bearing.

[0010] As a preferred embodiment of the above technical solution, the number of positioning holes and threaded holes are set accordingly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, centrifuge tubes to be centrifuged are inserted into a placement cylinder, ensuring that each tube is securely fixed inside. The adjusting rod is rotated to the desired angle. Once the desired angle is reached, a suitable positioning hole is selected, and the positioning rod is inserted into the corresponding threaded hole. The mounting end of the positioning rod is then manually threaded into the threaded hole to fix the adjusting rod. After ensuring all centrifuge tubes are correctly installed and fixed, the centrifuge can be started for centrifugation. Through the engagement of the locking and fixing components and the placement components, the device can simultaneously centrifuge test tubes in both oblique and vertical positions. The design of this device allows it to adapt to various centrifugation needs. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides a technical solution: a centrifuge for producing human fibrinogen, including a shell 1, a top cover 11 hinged to one side of the shell 1, a circular partition 12 fixedly connected to the inner side of the shell 1, a drive motor 13 fixedly installed on the inner bottom wall of the shell 1, a drive rod 14 fixedly connected to the output end of the drive motor 13, the top of the drive rod 14 vertically upward through the circular partition 12 and a support plate 15 fixedly sleeved on the outer wall of the top, the drive rod 14 and the circular partition 12 are rotatably connected by bearings, and a connecting block is sleeved on the outer wall of the drive rod 14. 16. The connecting block 16 is positioned above the tray 15. The top of the drive rod 14 is threaded with a nut 17 for fixing the connecting block 16. Multiple placement components 2 for placing centrifuge tubes are fixed in a ring array on the outer wall of the connecting block 16. In actual use, the connecting block 16 is first placed on the tray 15, and then the connecting block 16 is fixed by tightening the nut 17, thereby fixing the placement components 2 to the drive rod 14. The drive motor 13 is started, and the drive rod 14 drives the connecting block 16 and the placement components 2 (including centrifuge tubes) to rotate, thereby achieving the centrifugation effect.

[0021] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the placement component 2 includes support plates 21 symmetrically fixedly connected to the outer wall of the connecting block 16. An adjusting rod 22 is rotatably connected between the two support plates 21. Load plates 23 are fixedly connected to the outer walls of the two opposite sides of the adjusting rod 22. Multiple placement cylinders 24 for inserting centrifuge tubes are fixedly arranged in an array on the load plates 23. One end of the adjusting rod 22 passes through one of the support plates 21 and the end is provided with a snap-fit ​​fixing component 3. The snap-fit ​​fixing component 3 includes a positioning turntable 31 fixedly sleeved on the outer wall of the adjusting rod 22. Positioning holes 32 are arranged in an annular array on the positioning turntable 31. Multiple threaded holes 33 are arranged in an annular array on the side wall of the support plate 21 near the positioning turntable 31. The number of positioning holes 32 and threaded holes 33 are correspondingly arranged. Positioning rods 34 are inserted into the threaded holes 33 and positioning holes 32. The assembly end of the positioning rod 34 is connected to the threaded hole 34. The centrifuge tubes are connected by a threaded connection at hole 33. During use, the centrifuge tubes to be centrifuged are inserted into the placement cylinder 24, ensuring each tube is securely fixed within it. As needed, the adjusting rod 22 is rotated to the desired angle. Once the adjusting rod 22 reaches the required angle, a suitable positioning hole 32 is selected, and the positioning rod 34 is inserted into the positioning hole 32 and the corresponding threaded hole 33. The assembly end of the positioning rod 34 is then manually threaded into the threaded hole 33 to fix the adjusting rod 22. After ensuring all centrifuge tubes are correctly installed and fixed, the centrifuge can be started for centrifugation. Through the engagement of the locking and fixing components and the placement components, the device can simultaneously centrifuge test tubes in both oblique and vertical positions. The design of this device allows it to adapt to various centrifugation needs.

[0022] As one implementation method in this embodiment, such as Figure 1 As shown, a control panel 18 is embedded on the outer wall of the casing 1. The drive motor 13 is electrically connected to the control panel 18. The control panel 18 is equipped with a display screen and control elements such as buttons or knobs to display the current status of the centrifuge (such as speed, time, etc.) and allow users to input control commands (such as start, stop, adjust speed, etc.).

[0023] Working principle: When in use, insert the centrifuge tubes to be centrifuged into the placement cylinder 24, ensuring that each centrifuge tube is firmly fixed inside the placement cylinder 24. As needed, rotate the adjusting rod 22 to reach the required angle. After the adjusting rod 22 reaches the required angle, select a suitable positioning hole 32 and insert the positioning rod 34 into the positioning hole 32 and the corresponding threaded hole 33. Then, manually thread the mounting end of the positioning rod 34 into the threaded hole 33 to fix the adjusting rod 22. After ensuring that all centrifuge tubes are correctly installed and fixed, start the drive motor 13. The drive rod 14 drives the connecting block 16 and the placement assembly 2 to rotate, thereby achieving the centrifugation effect.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
