For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The residual plasma collection device 1 according to an embodiment of the present invention will be described below with reference to the drawings.

[0028] As Figures 1-3As shown, the residual plasma collection device 1 according to an embodiment of the present utility model includes a collection tank body 10, a centrifuge bucket 20, and a driving device 30.

[0029] The collection tank body 10 is adapted to collect plasma. The centrifuge bucket 20 is rotatably arranged in the collection tank body 10. A plurality of plasma through holes 21 are provided on the centrifuge bucket 20. The inside of the centrifuge bucket 20 is adapted to place the plasma bag 2. The driving device 30 is in transmission connection with the centrifuge bucket 20.

[0030] Specifically, when it is necessary to collect the residual plasma in the plasma bag, after the plasma bag 2 is broken, it is directly placed into the centrifuge bucket 20. The driving device 30 drives the centrifuge bucket 20 to rotate, and the residual plasma in the plasma bag 2 is thrown out by centrifugal force. The thrown plasma further passes through the plasma through holes 21 of the centrifuge bucket 20 and enters the collection tank body 10 for collection.

[0031] A plurality of plasma bags 2 can be stacked in the centrifuge bucket 20. The plasma bags 2 can be placed in the centrifuge bucket 20 in a direction along the chord of the centrifuge bucket 20 in the length direction. For example, as Figure 3 shown, the plasma bags 2 can be stacked into three groups in the centrifuge bucket 20. Each group includes a plurality of stacked plasma bags 2. The three groups of plasma bags 2 can be respectively located on the three sides of the inscribed triangle of the centrifuge bucket 20, so that the edges of the plasma bags 2 are in contact with the inner wall of the centrifuge bucket 20 to ensure that the plasma bags 2 follow the rotation of the centrifuge bucket 20.

[0032] A discharge port can be provided at the bottom of the collection tank body 10. The discharge port can be connected to other collection containers through a pipeline. A drainage structure adapted to guide the plasma to the discharge port, such as a drainage groove or a drainage slope, can also be provided on the bottom wall of the collection tank body 10.

[0033] For the residual plasma collection device 1 according to an embodiment of the present utility model, by providing the centrifuge bucket 20, the broken plasma bag 2 can be directly placed into the centrifuge bucket 20. The centrifuge bucket 20 drives the plasma bag 2 to rotate and throws out the residual plasma from the plasma bag 2 through centrifugal force and enters the collection tank body 10 through the plasma through holes 21 for collection. Compared with the residual plasma collection device in the related art, there is no need to set up a fixture, and the process of installing each plasma bag on the fixture one by one can be omitted, and the process of installing the fixture on the centrifuge column can also be omitted, making the operation of recovering the residual plasma more convenient and fast, making the operation of the residual plasma collection device 1 more convenient, shortening the time required for plasma collection, and improving the efficiency of collecting the residual plasma.

[0034] Moreover, by providing the centrifuge bucket 20 and directly placing the plasma bag 2 into the centrifuge bucket 20, compared with the residual plasma collection device in the related art, since the fixture is omitted, the fixture does not occupy the space inside the centrifuge bucket 20, and the centrifuge bucket 20 can fully accommodate the plasma bag 2, increasing the number of plasma bags 2 that can be accommodated in the centrifuge bucket 20 each time collection is performed, thereby further improving the collection efficiency of the residual plasma collection device 1.

[0035] In addition, by providing the centrifuge bucket 20, the collection tank body and the drive device of the original residual plasma collection device can be fully utilized, and the centrifuge column of the original residual plasma collection device is replaced with the centrifuge bucket 20, thereby facilitating the transformation of the original residual plasma collection device and reducing the manufacturing cost of the residual plasma collection device 1.

[0036] Therefore, the residual plasma collection device 1 according to the embodiments of the present invention has the advantages of convenient operation and high collection efficiency.

[0037] Next, the residual plasma collection device 1 according to specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0038] In some specific embodiments of the present invention, as Figures 1-3 shown, the residual plasma collection device 1 according to the embodiments of the present invention includes a collection tank body 10, a centrifuge bucket 20, and a drive device 30.

[0039] Advantageously, as Figure 2 and Figure 3 shown, a plurality of partition plates 23 are provided inside the centrifuge bucket 20, and the space inside the centrifuge bucket 20 is divided into a plurality of plasma bag placement spaces by the plurality of partition plates 23, and each of the plasma bag placement spaces is suitable for stacking the plasma bags 2. In this way, the displacement of the plasma bag 2 can be restricted by the partition plate 23, ensuring the centrifugal effect of the rotation of the centrifuge bucket 20 on the plasma bag 2.

[0040] More advantageously, as Figure 2 and Figure 3 shown, the partition plates 23 are arranged radially inside the centrifuge bucket 20 and are equally spaced along the circumferential direction of the centrifuge bucket 20. In this way, it is convenient to place the plasma bag 2, convenient to restrict the displacement of the plasma bag 2 in the circumferential direction of the centrifuge bucket 20 to ensure the centrifugal effect, and the obstruction of the plasma by the arrangement of the partition plates 23 can be reduced.

[0041] Furthermore, as Figure 2 shown, each partition plate 23 is provided with a plasma through hole 21. In this way, the obstruction of the plasma by the partition plate 23 can be further avoided, further improving the separation effect.

[0042] Specifically, the height of the upper edge of the partition plate 23 is less than or equal to the height of the upper edge of the centrifuge bucket 20 (the up and down direction is as shown by the arrow in the figure). In this way, it is convenient to place more plasma bags 2.

[0043] Figures 1-3 Shows a residual plasma collection device 1 according to some examples of the present utility model. As Figures 1-3 shown, a plurality of plasma through-holes 21 are arranged in an array on the peripheral wall and the bottom wall of the centrifuge bucket 20. In this way, both the bottom wall and the peripheral wall of the centrifuge bucket 20 can pass through the plasma, facilitating the plasma thrown out from the plasma bag 2 to drain from the centrifuge bucket 20 into the collection tank 10, so that the plasma is not easily left in the centrifuge bucket 20.

[0044] Specifically, as Figure 1 shown, the height of the upper edge of the collection tank 10 is greater than the height of the upper edge of the centrifuge bucket 20. This can ensure that the plasma thrown out from the centrifuge bucket 20 all falls into the collection tank 10 for collection, avoiding the plasma being thrown out of the collection tank 10.

[0045] Specifically, as Figure 1 shown, the driving device 30 is arranged below the collection tank 10 and has a rotating shaft 31, and the rotating shaft 31 passes through the collection tank 10 and is connected to the centrifuge bucket 20. Specifically, the driving device 30 can be a motor. In this way, the rotation of the rotating shaft 31 can be used to drive the centrifuge bucket 20 to rotate, so as to facilitate the transmission connection between the driving device 30 and the centrifuge bucket 20.

[0046] More specifically, the rotating shaft 31 is connected to the centrifuge bucket 20 through a plurality of threaded fasteners, and the plurality of threaded fasteners are offset from the central axis of the rotating shaft 31. This can prevent relative rotation between the centrifuge bucket 20 and the rotating shaft 31, ensuring reliable transmission of the driving force of the driving device 30 to the centrifuge bucket 20.

[0047] More advantageously, as Figure 1 shown, the centrifuge bucket 20 and the rotating shaft 31 are coaxially arranged. This can make the force on the centrifuge bucket 20 more uniform, and make the force on the plasma bag 2 in the centrifuge bucket 20 more uniform during plasma collection, further facilitating the improvement of the collection efficiency.

[0048] Figures 1-3 Shows a residual plasma collection device 1 according to some examples of the present utility model. As Figures 1-3 shown, the upper edge of the centrifuge bucket 20 is provided with an outward-turned edge 22. This can improve the structural strength and rigidity of the centrifuge bucket 20, avoiding deformation of the centrifuge bucket 20 during rotation.

[0049] Specifically, as Figure 1 shown, the centrifuge bucket 20 and the inner surface of the collection tank 10 are spaced apart. This can prevent the collection tank 10 from interfering with the rotation of the centrifuge bucket 20 and the discharge of the plasma in the centrifuge bucket 20, so as to facilitate the discharge of the plasma in the centrifuge bucket 20 into the collection tank 10, and further facilitate the collection of the plasma.

[0050] Optionally, the pore diameter of the plasma through-hole 21 is 3-15 mm. This can ensure that the plasma through-hole 21 has a sufficient pore diameter to facilitate the discharge of plasma from the centrifuge bucket 20 and also facilitate ensuring the structural strength of the centrifuge bucket 20.

[0051] Advantageously, the distance between two adjacent plasma through-holes 21 is 4-30 mm. This can prevent plasma from remaining in the centrifuge bucket 20 while ensuring the structural strength of the centrifuge bucket 20.

[0052] Specifically, the inner diameter of the centrifuge bucket 20 is 20-80 cm. This can facilitate ensuring the volume of the centrifuge bucket 20 and the number of plasma bags 2 that can be accommodated in the centrifuge bucket 20 each time.

[0053] Specifically, the inner diameter of the centrifuge bucket 20 can at least accommodate three stacked plasma bags 2 to ensure the number of plasma bags 2 that the centrifuge bucket 20 can accommodate.

[0054] Other components and operations of the residual plasma collection device 1 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
