[0031] See also Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of the first embodiment of the reagent bottle rack assembly of the present application, Figure 2 1 is a schematic diagram of the structure of the second embodiment of the reagent bottle rack assembly of the present application. The reagent bottle rack assembly 1 provided in the embodiment of the present application comprises a reagent bottle rack 11 and a guide member 12.
[0032] Among them, the reagent bottle rack 11 is used to place the reagent bottle 2, the first end of the reagent bottle rack 11 is provided with a sliding shaft 111, the guide member 12 is provided with a guide groove 121, one end of the sliding shaft 111 is arranged in the guide groove 121, and the sliding shaft 111 is slidably connected with the guide groove 121, and then when the sliding shaft 111 partially slides in the guide groove 121, it drives the reagent bottle rack 11 to rotate relative to the guide member 12.
[0033] The reagent bottle rack 11 rotates relative to the guide member 12 to move the reagent bottle 2 to a convenient replacement position, thereby reducing the difficulty for the user to replace the reagent bottle 2 on the reagent bottle rack 11 and improving the user's experience of using the reagent bottle rack assembly 1. In particular, for a reagent bottle 2 that is far from the replacement position, the reagent bottle rack 11 is rotated so that the height of the reagent bottle 2 that is far from the replacement position is slightly higher than the height of the reagent bottle 2 that is close to the replacement position, making it more convenient to replace the reagent bottle 2 that is far from the replacement position.
[0034] Optionally, the reagent bottle rack assembly 1 includes a push-pull member 13 .
[0035] The push-pull member 13 includes a first push-pull plate 131 and a second push-pull plate 132 connected to the first push-pull plate 131. The first push-pull plate 131 extends in the height direction of the reagent bottle rack assembly 1, and the second push-pull plate 132 extends along the length direction of the reagent bottle rack 11. The first push-pull plate 131 and the second push-pull plate 132 can move relative to the guide member 12.
[0036] The second push-pull plate 132 is connected to the guide member 12 for relative horizontal sliding along the first direction X. The direction in which the first push-pull plate 131 is away from the guide member 12 in the length direction of the reagent bottle rack 11 is defined as the first direction X. The multiple reagent bottle placement positions of the reagent bottle rack 11 are arranged in sequence along the first direction X.
[0037] In one embodiment, the guide member 12 is spaced apart from the reagent bottle rack 11 , so that the reagent bottle rack 11 can slide more smoothly relative to the guide member 12 .
[0038] In another embodiment, the second push-pull plate 132 is spaced apart from the guide member 12 , so that the second push-pull plate 132 can slide more smoothly relative to the guide member 12 .
[0039] Optionally, the reagent bottle rack assembly 1 further includes a support plate 14 .
[0040] The support plate 14 is disposed at one end of the second push-pull plate 132 away from the first push-pull plate 131 , and one end of the support plate 14 away from the second push-pull plate 132 is rotatably connected to the second end of the reagent bottle rack 11 .
[0041] Specifically, the user can pull the first push-pull plate 131 along the length direction of the reagent bottle rack 11 to move the first push-pull plate 131 away from the guide member 12, and the first push-pull plate 131 drives the second push-pull plate 132 to move, and the second push-pull plate 132 drives the reagent bottle rack 11 to move relative to the guide member 12 through the support plate 14. Since the sliding shaft 111 of the reagent bottle rack 11 is arranged in the guide groove 121, during the movement of the second push-pull plate 132 relative to the guide member 12, the reagent bottle rack 11 drives the sliding shaft 111 to move along the extension direction of the guide groove 121.
[0042] When the first push-pull plate 131 and the second push-pull plate 132 slide partially horizontally relative to the guide member 12 in the first direction X, the reagent bottle rack 11 rotates relative to the guide member 12 to rotate the reagent bottles on the reagent bottle rack 11 toward the user, so that the user can replace the reagent bottles on the reagent bottle rack 11. In one embodiment, the reagent bottle rack assembly 1 is arranged on a blood testing device, the blood testing device includes a main body, and the reagent bottle rack assembly 1 is arranged on the main body. The user stands in front of the blood testing device and pulls the first push-pull plate 131, and the reagent bottle rack 11 moves toward the user. After moving a certain distance, the reagent bottle rack 11 continues to move toward the user. At the same time, the reagent bottle rack 11 rotates relative to the support plate 14, and the reagent bottles on the reagent bottle rack 11 are rotated toward the user, that is, the reagent bottle farther from the replacement position is located above the reagent bottle closer to the replacement position, and the multiple reagent bottles on the reagent bottle rack 11 are tilted toward the user; or the bottle mouths of the multiple reagent bottles on the reagent bottle rack 11 are facing the user.
[0043] Optionally, see Figure 1 The guide groove 121 includes a first slide section and a second slide section, the first slide section extends horizontally along the length direction of the reagent bottle rack 11, that is, extends horizontally along the first direction X, and the second slide section extends obliquely downward along the first direction X, and the angle between the second slide section and the first slide section is an obtuse angle;
[0044] In the process that the first push-pull plate 131 and the second push-pull plate 132 slide horizontally along the first direction X relative to the guide member 12, if the sliding shaft 111 slides in the first sliding section, the reagent bottle rack 11 is driven by the second push-pull plate 132 to move along the first direction X in a vertical state. When the sliding shaft 111 is located in the second sliding section, the reagent bottle rack 11 is transformed from a vertical posture to an inclined posture. When the sliding shaft 111 is located in the second sliding section, the reagent bottle rack 11 is in an inclined posture relative to the guide member 12, so that the reagent bottle 2 on the reagent bottle rack 11 faces the user, which is convenient for the user to replace the reagent bottle 2 on the reagent bottle rack 11, thereby improving the convenience of the reagent bottle rack assembly 1.
[0045] After the user has replaced the reagent bottle 2, the user can push the first push-pull plate 131, and the first push-pull plate 131 drives the second push-pull plate 132 to move relative to the guide member 12 in the opposite direction of the first direction X, and then the sliding shaft 111 returns from the second sliding section to the first sliding section in the guide groove 121, and the reagent bottle rack 11 is transformed from an inclined state to a vertical posture, which facilitates the reagent bottle 2 on the reagent bottle rack 11 to participate in subsequent operations, thereby improving the practicality of the reagent bottle rack assembly 1.
[0046] In one embodiment, the first end of the reagent bottle rack 11 and the second end of the reagent bottle rack 11 are located on the same side of the reagent bottle rack 11 , so that the volume of the reagent bottle rack assembly 1 is reduced while adjusting the posture of the reagent bottle rack 11 .
[0047] Specifically, during the horizontal sliding of the first push-pull plate 131 and the second push-pull plate 132 relative to the guide member 12 along the first direction X, the support plate 14 is disposed on the second push-pull plate 132 and moves along with the second push-pull plate 132, that is, the reagent bottle rack 11 also moves along the first direction X. At this time, the sliding shaft 111 is located in the first sliding section of the guide groove 121, and the first sliding section extends horizontally along the length direction of the reagent bottle rack 11. The first direction X is the length direction of the reagent bottle rack 11, so the sliding shaft 111 also moves along the first direction X, and the reagent bottle rack 11 moves along the first direction X in a vertical posture.
[0048] When the sliding shaft 111 enters the second sliding section, the second end of the reagent bottle rack 11 still moves along the first direction X, while the first end of the reagent bottle rack 11 and the sliding shaft 111 move obliquely downward along the first direction X. Since the two ends of the same side of the reagent bottle rack 11 move in different directions, the reagent bottle rack 11 moves relative to the guide member 12 in the following manner: Figure 1The viewing angle is rotated counterclockwise, and when the sliding shaft 111 is located at the end point of the second sliding section, the reagent bottle rack 11 is located at the maximum tilt angle and faces the user at the maximum tilt angle that can be rotated, such as Figure 2 As shown, it is convenient for the user to replace the reagent bottle 2 on the reagent bottle rack 11.
[0049] Optionally, the push-pull member 13 further has a through hole 133 .
[0050] The through hole 133 is partially disposed at one end of the first push-pull plate 131 close to the second push-pull plate 132, and partially disposed at one end of the second push-pull plate 132 close to the first push-pull plate 131, and the reagent bottle rack 11 is partially located in the through hole 133. Therefore, when the reagent bottle rack 11 is tilted relative to the guide member 12, the second push-pull plate 132 will not block the reagent bottle rack 11, thereby affecting the tilting posture of the reagent bottle rack 11; and part of the through hole 133 located on the first push-pull plate 131 provides a force point for the user to pull the first push-pull plate 131, and the user can hold the first push-pull plate 131 through the through hole 133, and then pull the first push-pull plate 131, so that the first push-pull plate 131 drives the second push-pull plate 132 to move relative to the guide member 12, thereby improving the practicality of the reagent bottle rack assembly 1.
[0051] In other embodiments, all of the through holes 133 may be located at one end of the second push-pull plate 132 close to the first push-pull plate 131 to provide space for the rotation of the reagent bottle rack 11, and a handle is provided on the side of the first push-pull plate 131 close to the user, and the user can hold and pull the first push-pull plate 131 by the handle. The present application does not limit the specific setting position of the through holes 133 on the push-pull member 13.
[0052] Optionally, see Figure 2 , the reagent bottle rack assembly 1 further includes a sliding assembly 15. In one embodiment, the sliding assembly 15 includes a sliding rail 151, the second push-pull plate 132 includes a groove (not shown), and the sliding rail 151 is disposed on the body of the blood testing device; in another embodiment, the body includes a groove, and the sliding rail 151 is disposed on the second push-pull plate 132.
[0053] The sliding guide rail 151 can be slidably connected to the groove, and the groove is horizontally extended along the length direction of the reagent bottle rack 11. The second push-pull plate 132 and the guide member 12 are relatively horizontally slidably connected through the cooperation between the sliding guide rail 151 and the groove. When the first push-pull plate 131 drives the second push-pull plate 132 to move along the first direction X, the groove moves relative to the sliding guide rail 151, and then the second push-pull plate 132 drives the sliding shaft 111 to slide in the guide groove 121, so that the reagent bottle rack 11 slides relative to the guide member 12; when the second push-pull plate 132 drives the sliding shaft 111 to partially slide in the guide groove 121, the reagent bottle rack 11 slides and rotates relative to the guide member 12.
[0054] The following briefly describes the process of replacing the reagent bottle 2 in the reagent bottle rack assembly 1:
[0055] When the reagent bottle 2 in the reagent bottle rack assembly 1 needs to be replaced, the user pulls the first push-pull plate 131 along the first direction X. Due to the cooperation between the groove and the sliding guide rail 151, the second push-pull plate 132 moves along the first direction X close to the user, and the support plate 14 drives the second end of the reagent bottle rack 11 to move close to the user along the first direction X. At this time, the sliding shaft 111 is located in the first sliding section of the guide groove 121, and the first end of the reagent bottle rack 11 and the sliding shaft 111 also move close to the user along the first direction X. The reagent bottle rack 11 moves close to the user along the first direction X in a vertical posture.
[0056] When the sliding shaft 111 enters the second sliding section, since the second end of the reagent bottle rack 11 still moves along the first direction X close to the user, and the first end of the reagent bottle rack 11 moves obliquely downward along the first direction X close to the user, the reagent bottle rack 11 rotates relative to the guide member 12, and when the sliding shaft 111 is located at the end point of the second sliding section, the reagent bottle rack 11 is at the maximum tilt angle and faces the user at the maximum tilt angle that can be rotated, such as Figure 2 As shown, it is convenient for the user to replace the reagent bottle 2 on the reagent bottle rack 11.
[0057] After the user replaces the reagent bottle 2, the user pushes the first push-pull plate 131 in the opposite direction of the first direction X, and the first push-pull plate 131 drives the second push-pull plate 132 to move away from the user in the opposite direction of the first direction X, and then the support plate 14 drives the reagent bottle rack 11 to move away from the user in the first direction X, and the sliding shaft 111 on the reagent bottle rack 11 slides obliquely upward in the direction of the first direction X on the second sliding section, driving the reagent bottle rack 11 to move in the opposite direction of the first direction X. Figure 2 The viewing angle is rotated clockwise, and when the sliding shaft 111 is located at the connection between the first sliding section and the second sliding section, the reagent bottle rack 11 changes from the inclined posture to the vertical state. At this time, the user continues to push the first push-pull plate 131 until the sliding shaft 111 moves to the end point of the first sliding section away from the second sliding section, such as Figure 1 As shown, it is convenient for the reagent bottle 2 to participate in subsequent operations.
[0058] Alternatively, if Figure 2As shown, the reagent bottle rack 11 includes at least one reagent bottle placement position 112, each reagent bottle placement position 112 is used to place a sample tube reagent bottle 2, and the size of the reagent bottle 2 matches the corresponding reagent bottle placement position 112. For example, at least one set of relative outer walls of the reagent bottle 2 contacts the inner wall of the reagent bottle placement position 112, or the placement space enclosed by the inner wall of the reagent bottle placement position 112 is slightly larger than the size of the reagent bottle 2, so that the reagent bottle 2 can be fixed on the reagent bottle rack 11, avoiding the reagent bottle 2 from tipping over or falling off the reagent bottle rack 11 when the reagent bottle rack 11 rotates, thereby improving the safety of the reagent bottle rack assembly 1.
[0059] In summary, in the reagent bottle rack assembly 1 provided in the embodiment of the present application, the sliding shaft 111 at the first end of the reagent bottle rack 11 passes through the guide groove 121 of the guide member 12, and the second end of the reagent bottle rack 11 is rotatably disposed on the support plate 14, and the support plate 14 is disposed on the second push-pull plate 132. Then, when the first push-pull plate 131 drives the second push-pull plate 132 to move, since the moving direction of the first end of the reagent bottle rack 11 is different from the moving direction of the second end of the reagent bottle rack 11, the reagent bottle rack 11 rotates relative to the guide member 12, and the reagent bottle rack 11 changes from a vertical posture to an inclined state, which is convenient for the user to replace the reagent bottle 2 on the reagent bottle rack 11, reduces the difficulty of the user to replace the reagent bottle 2, and improves the user's experience of using the reagent bottle rack assembly 1.
[0060] This application also provides a blood testing device, see Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the structure of the first embodiment of the blood testing device of the present application, Figure 2 1 is a schematic diagram of the structure of the second embodiment of the blood testing device of the present application. The blood testing device A provided in the embodiment of the present application comprises a reagent bottle rack assembly 1 and a sampling needle assembly 3. The blood testing device A may be a blood cell analyzer, a sample analyzer, and the like.
[0061] The sampling needle assembly 3 is used to collect reagents from the samples in the reagent bottles 2 of the reagent bottle rack assembly 1 .
[0062] like Figure 3 As shown, the sampling needle assembly 3 is located above the reagent bottle rack assembly 1 , and the reagent bottle rack 11 in the reagent bottle rack assembly 1 is in a vertical posture. The sampling needle assembly 3 can sample the reagent in the reagent bottle 2 .
[0063] When the reagent in the reagent bottle 2 is insufficient, the reagent bottle 2 needs to be replaced. Figure 1 In this case, the user can pull the push-pull member 13 in the reagent bottle rack assembly 1 to move the reagent bottle rack 11 closer to the user and rotate it toward the user, as shown in FIG. Figure 2As shown, at this time, the user can replace the reagent bottle 2 on the reagent bottle rack 11, reducing the difficulty of the user to replace the reagent bottle 2. After the user has completed replacing the reagent bottle 2, the user can further push the push-pull member 13 to return the reagent bottle rack 11 to the position shown in FIG. Figure 1 In the position shown, the sampling needle assembly 3 further samples the reagent in the replaced reagent bottle 2.
