DETAILED DESCRIPTION
[0018] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.
[0019] Example: A plasma bag fixing device for plasma collection, such as... Figures 1-3 As shown, the system includes a plasma collection machine 1 and a fixing assembly 2. The plasma collection machine 1 is equipped with the fixing assembly 2, which is used to hold the plasma bag. The fixing assembly 2 includes a mounting base 21, bearings 22, hollow rotating shafts 23, fixed shafts 24, wedge blocks 25, sliders 26, and a return spring 27. The mounting base 21 is bolted to the plasma collection machine 1. Two bearings 22 are mounted on the mounting base 21. The inner ring of each bearing 22 is connected to a hollow rotating shaft 23. Two fixed shafts 24 are connected to the mounting base 21. 4 are located in two hollow rotating shafts 23 respectively. The hollow rotating shafts 23 can rotate relative to the fixed shaft 24. The front end of the fixed shaft 24 is provided with a sliding groove. Two wedge blocks 25 are provided in the sliding groove. A slider 26 is connected to the wedge block 25. The wedge block 25 is slidably connected to the fixed shaft 24 through the slider 26 and the sliding groove. A return spring 27 is connected between the two wedge blocks 25. The return spring 27 is used to reset the position of the wedge block 25 after it has moved. The front outer wall of the hollow rotating shaft 23 is provided with a through hole 231. The wedge block 25 passes through the through hole 231.
[0020] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a quick operation component 3, which includes a gear 31, a rack 32, a slide rail 33, and an operation plate 34. The gear 31 is connected to the rear of the hollow rotating shaft 23, the slide rail 33 is connected to the bottom right side of the rack 32, the slide rail 33 is slidably connected to the right side of the mounting base 21, the rack 32 meshes with the gear 31, and the operation plate 34 is connected to the right side of the rack 32.
[0021] like Figure 1 As shown, it also includes a tray 4, which is connected to the bottom of the mounting base 21. The tray 4 can support and place the plasma bag.
[0022] like Figure 1 As shown, it also includes a protective housing 5. The front of the mounting base 21 is connected to the protective housing 5. The bearing 22 and gear 31 are both located inside the protective housing. The hollow rotating shaft 23 and rack 32 pass through the protective housing 5. The protective housing 5 protects the bearing 22 and rack 32 and prevents foreign objects from affecting their use.
[0023] like Figure 3 As shown, it also includes rollers 6. Two rollers 6 are rotatably connected on the hollow shaft 23. The rollers 6 are located on one side of the through hole 231 and are in contact with the inclined surface of the wedge block 25.
[0024] like Figure 5 As shown, it also includes a magnet 7. The right side of the mounting base 21 and the left side of the slide rail 33 are both connected to the magnet 7, and the two magnets 7 are attracted to each other.
[0025] When collecting plasma using the plasma collection machine 1, first, the control plate 34 pushes the rack 32 to the left, disengaging the two magnets 7. The rack 32 drives the gear 31 to rotate, thereby causing the hollow shaft 23 to rotate counterclockwise. This causes the roller 6 to press the wedge block 25, making it slide through the through hole 231 into the groove of the fixed shaft 24. The return spring 27 deforms, at which point the plasma bag can be placed on the tray 4 and hung on the hollow shaft 23. Then, the control plate 34 is pushed backward, causing the rack 32 to drive the gear 31 to rotate clockwise, which in turn drives the hollow shaft 23 to rotate clockwise. The roller 6 no longer presses the wedge block 25, and the return spring 27 returns to its original position. The wedge block 25 slides outward and through the through hole 231, blocking the front of the blood plasma bag and preventing it from falling accidentally. When the rack 32 moves to the right, the slide rail 33 drives the magnet 7 to move to the right, so that the two magnets 7 attract each other, thereby stabilizing the position of the rack 32. Thus, simply pushing the operating plate 34 can cause the wedge block 25 to retract or expand, making it convenient to place the blood plasma bag and preventing it from falling accidentally during use, thereby increasing the stability of the blood plasma bag. When it is necessary to remove the blood plasma bag, repeat the above operation to retract the wedge block 25 into the slide groove, and then move the blood plasma bag forward to remove it from the hollow rotating shaft 23.
[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
