[0037] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0038] Embodiment 1

[0039] Referring to Figures 1 - 5 , a blood bag bin for blood preparation in this embodiment includes:

[0040] The outer shell 1 is internally provided with a preservation liquid chamber 10, a transfer bag chamber 11, and a whole blood bag chamber 12 in sequence along the X direction. A holding frame 2 is fixedly arranged inside the outer shell 1. A first push plate 3 and a second push plate 4 that can slide along the X direction are respectively connected to both sides of the holding frame 2. The cavity inside the holding frame 2 forms the transfer bag chamber 11. The cavity between the holding frame 2 and the first push plate 3 forms the preservation liquid chamber 10. The cavity between the holding frame 2 and the second push plate 4 forms the whole blood bag chamber 12. Openings 13 are arranged on both sides of the outer shell 1 along the X direction. The preservation liquid chamber 10, the transfer bag chamber 11, and the whole blood bag chamber 12 are used to place the preservation liquid bag, the transfer bag, and the whole blood bag in the triple blood bag respectively;

[0041] Among them, each of the preservation liquid bag, the transfer bag, and the whole blood bag is connected with a branch pipeline, and the 3 branch pipelines are communicated through a main pipeline.

[0042] And a hose fixing member 5, which includes a fixing plate 50 rotatably arranged on the outer shell 1 and 3 hose fixing units 51 arranged on the fixing plate 50. The hose fixing unit 51 is used to place and fix the hoses on the triple blood bag and provide a heat-sealing area for squeezing and heat-sealing the hoses to seal the hoses.

[0043] Among them, the first push plate 3 is connected to the first side of the holding frame 2 through four first guide shafts 30, and the first push plate 3 can slide along the X direction on the first guide shafts 30. The second push plate 4 is connected to the second side of the holding frame 2 through four second guide shafts 40, and the second push plate 4 can slide along the X direction on the second guide shafts 40. Return springs (not shown in the figure) are sleeved on both the first guide shafts 30 and the second guide shafts 40 to realize the reset of the first push plate 3 and the second push plate 4.

[0044] Among them, both the first push plate 3 and the second push plate 4 are made of transparent materials to facilitate observing the color inside the whole blood bag to control the squeezing of the whole blood bag.

[0045] Among them, a weight bin 20 is further arranged on the holding frame 2, and a number of weight fixing holes 21 are opened at the bottom of the weight bin 20. By placing weights of different weights to balance the blood bag chamber, the precondition for centrifugation is achieved.

[0046] Among them, the hose fixing unit 51 includes a hose groove 52 opened on the fixing plate 50, a heat-sealing through groove 53 opened on the soft groove and penetrating the fixing plate 50 up and down, and two hose fixing block groups 54 arranged at both ends of the hose groove 52. The heat-sealing through groove 53 forms a heat-sealing area for squeezing and heat-sealing the hoses. The hose fixing block group 54 includes two fixing blocks 55 symmetrically arranged on both sides of the hose groove 52. A convex portion 56 protrudes outward from the middle of the inner side of the fixing block 55. A hose clamping groove 57 is formed between the two convex portions 56 on the two relatively arranged fixing blocks 55 in the hose fixing block group 54, and the width of the hose clamping groove 57 is smaller than the diameter of the hose.

[0047] During use, the branch pipelines of the maintenance liquid bag, the transfer bag, and the whole blood bag are respectively fixed by a hose fixing unit 51. The branch pipelines are manually pressed into the hose slots 52, and part of the branch pipelines are placed in the heat-sealing through slots 53, while the main pipeline is located away from the heat-sealing through slots 53 and the hose slots 52. Since the width between the hose card slots 57 is smaller than the diameter of the hose, the branch pipelines can be well fixed at both the head and tail ends by two groups of hose fixing block groups 54, which is beneficial for pressing and extrusion heat-sealing operations on the branch pipeline parts in the heat-sealing through slots 53.

[0048] Among them, the fixing plate 50 is connected to the housing 1 through a hinge 58. A plurality of magnets 14 are arranged on the housing 1 on the opposite side of the hinge 58, and a magnet 14 mating part for attracting with the magnets 14, such as an iron sheet or a magnet sheet, is arranged at the bottom of the fixing plate 50.

[0049] Among them, a positioning card slot 15 is formed on the outer side of the housing 1 for positioning the blood bag bin in the extrusion heat-sealing mechanism 6.

[0050] As the carrier of the triple blood bag, the blood bag bin of the present invention cooperates with a centrifugal device, an extrusion heat-sealing mechanism 6, etc. When performing whole blood preparation, for the convenience of understanding, the following provides an example of an extrusion heat-sealing mechanism 6 that cooperates with it:

[0051] Refer to Figures 6 - 8 , the extrusion heat-sealing mechanism 6 includes two push plate driving mechanisms 60 for respectively applying thrust to the first push plate 3 and the second push plate 4, three heat-sealing units 61 for performing extrusion heat-sealing on the hose, and a fixing box 62 for placing the blood bag bin; among them, the heat-sealing unit 61 includes a fixed electrode block 63 and a moving electrode block 64. The three heat-sealing units 61 correspond to the three hose fixing units 51 one by one, and the fixed electrode block 63 is located below the heat-sealing through slot 53, and the moving electrode block 64 is located above the heat-sealing through slot 53. The moving electrode block 64 can move relative to the fixed electrode block 63 in the vertical direction. When the two electrode blocks are mutually extruded, the hose can be temporarily clamped through the pressure action to temporarily seal the hose, and the two electrode blocks can also generate a high-frequency electromagnetic field to melt and heat-seal the plastic hose sandwiched in the middle. Positioning blocks 65 are arranged on the inner wall of the fixing box 62, and ball plungers (not shown in the figure) are arranged on the positioning blocks 65.

[0052] The following describes the main process of using the blood bag bin for whole blood preparation in combination with the above extrusion heat-sealing mechanism 6 for the convenience of understanding the present invention. Refer to Figure 9 , the main process includes:

[0053] 1. First, place the blood bag bin in a centrifuge (during this process, balance the blood bag bin by placing weights of different masses in the weight bin 20 to meet the preconditions for centrifugation), so that the whole blood in the whole blood bag is stratified, with plasma (yellow) on the upper layer and red blood cells (red) on the lower layer;

[0054] 2. Then, place the blood bag bin into the fixed box 62 of the extrusion and heat-sealing mechanism 6, and make the ball plunger on the positioning block 65 fit and push into the positioning card slot 15 of the outer shell 1 to achieve the positioning of the blood bag bin; the branch pipelines of the preservative solution bag, the transfer bag, and the whole blood bag are respectively loaded onto 3 hose fixing units 51;

[0055] 3. The two electrode blocks corresponding to the hose fixing unit 51 where the branch pipeline of the preservative solution bag is located are mutually extruded, tightly pressing and temporarily sealing the branch pipeline of the preservative solution bag. Then, apply a thrust in the X direction to the second push plate 4 through a push plate driving mechanism 60 to extrude the whole blood bag, so that all the plasma on the upper layer of the whole blood bag is squeezed into the transfer bag. During this process, the color sensor in the extrusion and heat-sealing mechanism 6 can be used to judge the critical point, that is, when the color sensor detects the appearance of red substances (red blood cells) in the branch pipeline of the whole blood bag, stop extrusion;

[0056] 4. The two electrode blocks corresponding to the hose fixing unit 51 where the branch pipeline of the transfer bag is located are mutually extruded, tightly pressing and temporarily sealing the branch pipeline of the transfer bag. Then, apply a thrust in the X direction to the first push plate 3 through another push plate driving mechanism 60 to extrude the preservative solution bag, and squeeze all the preservative solution into the whole blood bag to obtain a red blood cell preservative solution mixture in the whole blood bag;

[0057] 5. The 3 pairs of electrode blocks on the 3 hose fixing units 51 all work, and the moving electrode block 64 and the fixed electrode block 63 are pressed tightly to generate a high-frequency electromagnetic field, melting and heat-sealing the hoses clamped in the middle. Take out the blood bag bin, and then take out the preservative solution bag, the transfer bag, and the whole blood bag from the blood bag bin to complete the preparation of whole blood. The first push plate 3 and the second push plate 4 are reset under the action of the return spring.

[0058] Although the embodiments of the present invention have been disclosed as above, it is not limited to only the applications listed in the description and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details.
