Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary device for balancing and adjusting a centrifuge for blood cell component preparation. Background Technology

[0002] Blood typing centrifuges are medical devices widely used in blood serology, routine blood typing, red blood cell washing, microcolumn gel immunoassay, etc. They are of great significance for clinical trials and analysis. The balance regulation auxiliary device is installed inside the centrifuge to help maintain the balance of the preparation device and the blood inside.

[0003] Currently, when medical staff place a blood-filled preparation container into a balance adjustment auxiliary device, and need to balance the weight of this device, another preparation container needs to be placed in the opposite balance adjustment auxiliary device. An equal weight of water is added to this preparation container to balance the weight for measurement. However, the push rod of this water-adding preparation container needs to be broken during use, making it unusable and resulting in a certain waste of resources. The balance adjustment auxiliary device does not have a dedicated weight adjustment device to avoid wasting preparation containers and reduce usage costs. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the prior art, a balance adjustment auxiliary device for a blood bank component preparation centrifuge includes a centrifuge body 1 and a control panel 2. The operator controls the centrifuge body 1 through the control panel 2. A drive shaft 3 is installed in the middle of the centrifuge body 1. A drive motor is installed inside the centrifuge body 1. The motor shaft of the drive motor is connected to the drive shaft 3 to drive the drive shaft 3 to rotate. A bracket 4 is installed on the drive shaft 3. Centrifuge tubes 5 are fixedly arranged around the bracket 4. The drive shaft 3 drives the bracket 4 and the centrifuge tubes 5 to rotate. An external thread 2 is provided on the outer wall of the centrifuge tube 5, and a cover 2 14 is threadedly connected to it. The cover 2 14 is installed on the centrifuge tube 5 by means of threaded connection.

[0024] Please see Figure 1-2 This utility model discloses a balance adjustment auxiliary device for a centrifuge used for preparing blood components in a blood bank. The centrifuge tube 5 has an internal cavity, with the upper part of the cavity extending through the upper part of the centrifuge tube 5. A storage tube 6 is inserted into the cavity, and a preparer is placed in one of the storage tubes 6. Centered on the center of the drive shaft 3, the opposite centrifuge tube 5 stores water to balance the weight on both sides. A slot 12 is provided on the upper part of the centrifuge tube 5, and a retaining plate 13 is fixedly installed on the outer wall of the storage tube 6, engaging with the slot 12. Inserting the retaining plate 13 into the slot 12 secures the storage tube 6, preventing it from falling off during high-speed rotation. The upper outer wall of the storage tube 6... An external thread is provided at the location, and a cover 7 is threadedly connected to it. The cover 7 is threadedly connected to the storage tube 6 containing water to prevent the water inside from escaping during centrifugation. A spring 8 is fixedly installed at the lower part of the cover 7, and a sealing plate 9 is fixedly installed at the lower part of the spring 8. The spring 8 pushes the sealing plate 9 into the storage tube 6 and presses it onto the liquid surface. When balancing the weight of the two storage tubes 6, the storage tube 6 containing the preparer is not equipped with the cover 7 and the spring 8. The other storage tube 6 stores water, the cover 7, and the spring 8. The weight of the preparer is weighed externally using a weighing device to ensure that the weight of the preparer is equal to the weight of the water, the cover 7, and the spring 8.

[0025] The outer wall of the sealing plate 9 is attached to the inner wall of the storage tube 6 to prevent water from moving to the upper part of the sealing plate 9 through the gap between the two. A sealing gasket 10 is fixedly installed at the lower part of the sealing plate 9. The sealing gasket 10 can improve the sealing performance and further prevent water from moving to the upper part of the sealing plate 9 through the gap between the sealing plate 9 and the storage tube 6.

[0026] A guide rod 11 is fixedly installed in the middle of the cover 7. A through hole is provided in the middle of the sealing plate 9, and it is arranged through the guide rod 11. Another through hole is provided in the middle of the sealing gasket 10, and it is arranged through the guide rod 11. After the centrifugation is completed, the cover 7 is removed from the storage tube 6. At this time, the guide rod 11 guides the sealing plate 9 and the sealing gasket 10 to prevent them from swaying left and right. Then, the storage tube 6 for storing water is removed from the centrifuge tube 5 and the water is poured out.

[0027] In summary, the balance adjustment auxiliary device for the blood bank component preparation centrifuge involves using a weighing device to accurately weigh the storage tube 6 and the preparer in a storage dish. After weighing, the preparer is removed. Then, by adding or subtracting components, another storage tube 6, a cap 7, and a spring 8 are placed in the storage dish. Water is added to the storage tube 6, and when the total weight equals the weight of the storage tube 6 and the preparer, water addition is stopped. The cap 7 is then threaded onto the water-filled storage tube 6 via its internal thread to the external thread on the upper outer wall of the storage tube 6. After the cap 7 is installed, the spring 8 pushes the sealing plate 9 into the storage tube 6, pressing it onto the liquid surface. Simultaneously, ensure the outer wall of the sealing plate 9 fits tightly against the inner wall of the storage tube 6, and the sealing gasket 10 at its lower part further enhances the sealing effect. Place the storage tube 6 into one of the centrifuge tubes 5, and then place the storage tube 6 containing the preparer into the centrifuge tube 5 on the opposite side, with the center of the drive shaft 3 as the reference. Then screw the cover 14 onto the centrifuge tube 5 to fix the storage tube 6 in place, and start the device to perform the separation operation. After the centrifugation operation is completed, turn off the centrifuge. After the centrifuge has completely stopped rotating, remove the preparer from the storage tube 6, and then remove the cover 7 from the water-filled storage tube 6. During the removal process, the guide rod 11 in the middle of the cover 7 guides the sealing plate 9 and the sealing gasket 10 to prevent them from shaking. Then remove the water-filled storage tube 6 from the centrifuge tube 5 and pour out the water. Finally, clean and organize all used parts to prepare for the next use.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
