[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example 1: As Figures 1 to 3 As shown, in this embodiment, the blood bag holder of the leukemia blood monitoring instrument mainly consists of a top mounting component 3 and a hanging plate 2. The top mounting component 3 is used to connect to the frame of the leukemia blood monitoring instrument (not shown). The hanging plate 2 is installed through the top mounting component 3, so that the gravity of the hanging plate 2 is transferred to the external frame. Specifically, the top mounting component 3 includes a top plate 31, which rests on the upper surface of the top frame of the leukemia blood monitoring instrument or is connected to the top frame of the leukemia blood monitoring instrument. The top plate 31 has elongated holes around its perimeter for fixing to the frame, which facilitates the adjustment of the relative position of the top plate 31 and the frame. The hanging plate 2 is directly or indirectly rotatably connected to the top plate 31. When directly connected, the top of the hanging plate 2 forms a rotating shaft. In order to reduce the processing difficulty, a boss 311 is sleeved in the middle of the top plate 31. The boss 311 is connected to the hanging plate 2 and supports the rotation of the hanging plate 2.

[0024] like Figure 2 A planar bearing (not marked) is provided between the boss 311 and the top plate 31 to facilitate the rotation of the hanging plate 2. The boss 311 is hollow, that is, a cylindrical hole is provided in the middle of the boss 311 to reduce the weight of the boss 311.

[0025] like Figure 3 The hanging tray 2 includes a cover 21 and a mounting frame 22. The cover 21 surrounds the mounting frame 22. The bottom of the cover 21 and the mounting frame 22 are connected. The bottom of the mounting frame 22 is provided with several hooks 23. The hooks 23 extend out of the cover and are used to hang the blood bag 1. Each hook 23 is connected to a tension sensor 24 and an indicator light 25. The indicator light 25 is used to display the working status of the equipment: green before starting work, yellow during operation, and red when there is an abnormality. When there is an abnormality, a buzzer will sound an alarm.

[0026] like Figure 3 The top of the mounting bracket 22 is provided with a gear disk 26 that drives the drive plate 2 to rotate. The top of the mounting bracket 22 is connected to the boss 311. The boss 311 provides a certain distance between the mounting bracket 22 and the top plate 31, providing installation space for the gear disk 26 and the drive mechanism 27. The drive mechanism 27 can be a stepper motor or other power device that can intermittently drive the gear disk 26 to rotate (not shown). The output gear of the drive mechanism 27 meshes with the gear disk 26, and drives the plate 2 to rotate around the top plate 31 through the gear disk 26.

[0027] like Figures 1-4 The hanging plate 2 can utilize the outer cover 21 and the driven structure. The driven mechanism can be the column 4. Taking the column 4 as an example, the cover 21 is generally made of plastic, which has low strength. This results in low strength of the connection between the cover 21 and the column 4, which is not conducive to service life. In order to ensure connection stability, the cover 21 has a bottom hole (not marked) in the middle, which is used to fit over the column 4 so that the column 4 can pass through. The mounting bracket 22 is connected to the column 4 to drive the column 4 to rotate.

[0028] Example 1: During assembly: Connect the top plate 31 to the external frame, rotatably connect the boss 311 to the top plate 31, and connect the mounting bracket 22 to the boss 311 to complete the blood bag hanger connection. When connecting the blood bag hanger to the driven mechanism, the boss 311 moves upward or the entire blood bag hanger moves upward to make room for the installation of the column 4. Once the column 4 is upright, the boss 311 or the hanging plate 2 moves downward, and the connecting plate 41 of the column 4 passes through the cover 21 and connects with the mounting bracket 22 to complete the assembly.

[0029] Example 2: In Example 1, after the column is erected, it is not easy to install between the mounting bracket 22 and the column 4. In order to solve this problem, the mounting bracket 22 is provided with a groove 221 in the middle. The hanging plate 2 moves down and the column is inserted into the groove 221, thus completing the assembly.

[0030] like Figures 3-5 The mounting bracket 22 is designed with a plug-in structure. The column 4 is driven to rotate by the hanging plate 2. Correspondingly, multiple connecting plates 41 or connecting pins need to be set at the end of the column 4. The column 4 is usually equipped with a telescopic drive mechanism. It is a hollow column with low strength. If the connecting plate 41 or connecting pin is not supported by a support 42, the connection strength between the column 4 and the mounting bracket 22 is low. There is a risk of deformation and cracking at the connecting plate 41 of the column 4. In order to solve this problem, the mounting bracket 22 of the hanging plate 2 is connected by a top seat 33 and a boss 311. The bottom of the top seat 33 is provided with a groove 331 corresponding to the groove 221. The top seat 33 is a cylindrical structure. The inside of the top seat 33 forms the mounting cavity for the support 42 of the column 4.

[0031] like Figure 5 Since the top support 42 of the column 4 needs to be installed, the mounting bracket 22 cannot be fixed to the boss 311 in advance, and the boss 311 cannot be moved up and down to make room for the column 4. Therefore, the fixing method between the top seat 33 and the boss 311 is as follows: the top seat 33 and the boss 311 are fixed around the perimeter by fasteners (not shown). The fasteners can be screws, and the fasteners are arranged radially along the top seat 33. Thus, before the column 4 is assembled, the top of the mounting bracket 22 of the hanging plate 2 is connected to the bottom of the top seat 33. The hanging plate 2 and the top seat 33 are pre-fitted onto the column 4 through the grooves 221 and 331. After the top support 42 of the column 4 is installed and the column 4 is upright, the hanging plate 2 and the top seat 33 slide along the column 4 to the top of the column 4, and then form a perimeter connection with the boss 311.

[0032] like Figures 4-5 In order to enable the top seat 33 to slide along the column 4 and reduce the processing difficulty, the top seat 33 is connected to the bottom of the boss 311 through the top cover 32 and the bottom of the boss 311 in conjunction with the boss 311 with a smaller outer diameter. The top of the top cover 32 is connected to the boss 311 through fasteners (not shown) along the axial direction of the boss. The top cover 32 and the top seat 33 are fixed around the perimeter by fasteners.
