[0034] See also Figure 1 and Figure 2 , Figure 1 It is a structural schematic diagram of the first embodiment of the reagent bottle support assembly of the present application; Figure 2 The figure is a schematic diagram of the structure of the second embodiment of the reagent bottle support assembly of the present application. The reagent bottle support assembly 1 provided in the embodiment of the present application is used to support a reagent bottle, and the reagent bottle support assembly 1 is applied to a detection device, and the detection device includes a sample needle assembly, and the sample needle assembly collects reagents from a reagent bottle 2 in the reagent bottle support assembly 1.
[0035] The reagent bottle supporting assembly 1 includes a reagent bottle mounting seat 11 and an elastic member 12 .
[0036] The reagent bottle mounting seat 11 is provided with a receiving space 111 for placing the reagent bottle 2; the elastic member 12 is provided on the reagent bottle mounting seat 11, and when the reagent bottle 2 is placed in the reagent bottle mounting seat 11, the elastic member 12 is located between the reagent bottle 2 and the reagent bottle mounting seat 11. When the sample needle assembly collects reagents from the reagent bottle 2 and the sample needle 41 of the sample needle assembly contacts the bottom of the reagent bottle 2, since the elastic member 12 is provided between the reagent bottle 2 and the reagent bottle mounting seat 11, the reagent bottle 2 can move in a direction away from the sample needle 41 and compress the elastic member 12.
[0037] When the reagent in the reagent bottle 2 is insufficient and the sample needle 41 still needs to collect the reagent in the reagent bottle 2, the sample needle 41 is likely to contact the bottom of the reagent bottle 2. When the sample needle 41 contacts the bottom of the reagent bottle 2, the reagent bottle 2 will move away from the sample needle 41 and compress the elastic member 12, thereby preventing the sample needle 41 from piercing the bottom of the reagent bottle 2 or the sample needle 41 from colliding with the bottom of the reagent bottle 2 and damaging the sample needle 41, thereby improving the safety of the reagent bottle 2 and the sample needle 41 in the process of collecting reagents from the reagent bottle 2, and improving the practicality of the reagent bottle support assembly 1.
[0038] In one embodiment, the elastic member 12 can be compressed by 0.1mm-10mm during this process, that is, the reagent bottle 2 can move relatively away from the sample needle 41 by a distance of 0.1mm-10mm, ensuring that the reagent in the reagent bottle 2 is completely absorbed and the sample needle 41 is not pierced by the reagent bottle 2, thereby improving the utilization rate of the reagent in the reagent bottle 2 and ensuring the safety of the reagent bottle 2 and the sample needle 41.
[0039] In another embodiment, if Figure 1As shown, when the elastic member 12 is compressed, the elastic member 12 is subjected to the gravity of the reagent bottle 2 and the force of the reagent bottle 2 away from the sample needle 41 (the force of the sample needle 41 on the bottom of the reagent bottle 2). When the sample needle 41 has finished collecting the reagent, the sample needle 41 is away from the bottom of the reagent bottle 2. At this time, the force applied by the sample needle 41 to the bottom of the reagent bottle 2 disappears, that is, the force of the reagent bottle 2 away from the sample needle 41 disappears, and the elastic member 12 is only subjected to the gravity of the reagent bottle 2. The elastic member 12 gradually stretches from the original compressed state until the force is balanced with the gravity of the reagent bottle 2. At this time, the reagent bottle 2 returns to the initial position of the reagent bottle 2 before the sample needle 41 collects the reagent, which facilitates the sample needle 41 to collect the reagent from the reagent bottle 2 again, thereby improving the efficiency of the sample needle 41 in collecting the reagent. This avoids the situation where the sample needle 41 moves the reagent bottle 2 away from the sample needle 41 and does not return to the initial position after the previous movement, and the sample needle 41 needs to move a larger distance next time to absorb the reagent in the reagent bottle 2, thereby reducing the energy consumption of the sample needle 41 when collecting the reagent and improving the practicality of the reagent bottle support assembly 1.
[0040] Optionally, the reagent bottle supporting assembly 1 further includes a supporting plate 13 .
[0041] The support plate 13 and the reagent bottle mounting seat 11 are relatively slidably arranged, and the elastic member 12 is arranged between the support plate 13 and the reagent bottle mounting seat 11. When the reagent bottle 2 is placed in the reagent bottle mounting seat 11, the reagent bottle 2 is placed on the support plate 13 to avoid the elastic member 12 directly contacting the reagent bottle 2 and damaging the surface of the reagent bottle 2, or the reagent bottle 2 cannot be stably placed on the reagent bottle mounting seat 11 due to the mismatch between the elastic member 12 and the bottle bottom size of the reagent bottle 2. The support plate 13 provided in this embodiment isolates the reagent bottle 2 from the elastic member 12, and ensures the safety of the reagent bottle 2 while ensuring that the reagent bottle 2 can move relative to the sample needle 41.
[0042] Optional, such as Figure 2 As shown, the side of the support plate 13 near the bottom of the reagent bottle mounting seat 11 includes a plurality of guide rods 131. One side of the bottom of the reagent bottle mounting seat 11 includes a plurality of guide holes 112. The guide rods 131 and the guide holes 112 both extend along the first direction X, the guide holes 112 are arranged correspondingly to the guide rods 131, and the guide rods 131 and the guide holes 112 are arranged to slide relative to each other. Wherein the number of the guide holes 112 and the guide rods 131 is arranged correspondingly, for example, the support plate 13 includes N guide rods 131, and the reagent bottle mounting seat 11 also includes N guide holes 112; and the guide holes 112 and the guide rods 131 are arranged correspondingly in position, so that the guide rods 131 can be located in the guide holes 112 and slide relative to the guide holes 112. Wherein, the first direction X is the direction from the bottom of the reagent bottle support assembly 1 toward the top of the reagent bottle support assembly 1.
[0043] In one embodiment, when the sample needle 41 contacts the bottom of the reagent bottle 2, the guide rod 131 can move in the opposite direction of the first direction X close to the bottom of the guide hole 112, so as to drive the support plate 13 to move in the opposite direction of the first direction X close to the bottom of the reagent bottle mounting seat 11, and then the reagent bottle 2 moves away from the sample needle 41 in the opposite direction of the first direction X.
[0044] The cooperation between the guide hole 112 and the guide rod 131 ensures that when the sample needle 41 contacts the bottom of the reagent bottle 2, the reagent bottle 2 can move in the opposite direction of the first direction X instead of moving in an uncontrollable direction, thereby ensuring the safety of the reagent bottle 2 moving on the reagent bottle mounting seat 11.
[0045] Optionally, the elastic member 12 includes a plurality of spring members 121 , the plurality of spring members 121 correspond one-to-one to the plurality of guide rods 131 , the spring members 121 are sleeved on the corresponding guide rods 131 , and the spring members 121 and the guide rods 131 are both slidably disposed in the guide holes 112 .
[0046] When the sample needle 41 contacts the bottom of the reagent bottle 2, the guide rod 131 moves in the opposite direction of the first direction X to approach the bottom of the guide hole 112, and the support plate 13 moves in the opposite direction of the first direction X, so that the reagent bottle 2 moves away from the sample needle 41 from the initial position in the opposite direction of the first direction X and compresses the spring member 121. This avoids the reagent bottle 2 being pierced by the sample needle 41 or the sample needle 41 being damaged, thereby improving the safety of the reagent bottle 2 and the sample needle 41. As can be seen from the foregoing, the initial position of the reagent bottle 2 is the position of the reagent bottle 2 before the sample needle 41 collects the reagent.
[0047] When the sample needle 41 has finished collecting the reagent and the contact between the sample needle 41 and the bottom of the reagent bottle 2 is transformed into the sample needle 41 being away from the bottom of the reagent bottle 2, the spring member 121 is extended, driving the guide rod 131 to move away from the bottom of the guide hole 112 along the first direction X. Specifically, when the spring member 121 is extended, a force is applied to the support plate 13 to move away from the bottom of the guide hole 112. At the same time, due to the restrictions of the guide rod 131 and the guide hole 112, the support plate 13 can only move away from the bottom of the reagent bottle mounting seat 11 along the first direction X, and drive the guide rod 131 to move away from the bottom of the guide hole 112 along the first direction X. The reagent bottle 2 returns to the initial position, which is convenient for the sample needle 41 to collect the reagent in the reagent bottle 2 again. The practicality of the reagent bottle support assembly 1 is improved.
[0048] Among them, the support plate 13, the spring member 121 and the guide rod 131 can all be arranged in the accommodating space 111, so that when the reagent bottle 2 is placed in the accommodating space 111, the reagent bottle 2 can be placed on the support plate 13 and move in the opposite direction of the first direction X to compress the spring member 121 sleeved on the guide rod 131, or the spring member 121 on the guide rod 131 is extended to drive the support plate 13 and the reagent bottle 2 to move along the first direction X.
[0049] In summary, in the reagent bottle support assembly 1 provided in the embodiment of the present application, the cooperation of the elastic member 12 with the reagent bottle mounting seat 11 and the support plate 13 allows the reagent bottle 2 to move in the first direction X, so that when the sample needle 41 contacts the bottom of the reagent bottle 2, the reagent bottle 2 moves away from the sample needle 41 in the opposite direction of the first direction X, thereby preventing the sample needle 41 from piercing the bottom of the reagent bottle 2 to cause reagent leakage or damage to the sample needle 41. At the same time, when the sample needle 41 is away from the bottom of the reagent bottle 2, the reagent bottle 2 can return to the initial position, which is convenient for the sample needle 41 to collect reagents again, thereby improving the practicality of the reagent bottle support assembly 1.
[0050] Optionally, the detection device further includes a reagent bottle detection component (not shown), which is spaced apart from the reagent bottle elastic component and is used to detect the amount of reagent in the reagent bottle 2 .
[0051] After the reagent bottle 2 is placed on the reagent bottle mounting seat 11, the control unit on the detection device controls the sample needle 41 to move a preset distance in the vertical direction to enter the reagent bottle 2 for reagent collection, wherein the preset distance is negatively correlated with the amount of reagent in the reagent bottle 2 detected by the reagent bottle detection component.
[0052] For example, when the reagent bottle detection component detects that there is a large amount of reagent remaining in the reagent bottle 2, the control unit can control the sample needle 41 to move a smaller distance to enter the reagent bottle 2 to collect the reagent, so as to avoid the sample needle 41 entering the reagent too deeply and the sample needle 41 carrying the reagent on its surface, thereby wasting the reagent.
[0053] When the reagent bottle detection component detects that the amount of reagent remaining in the reagent bottle 2 is small, the control unit can control the sample needle 41 to move a larger distance to enter the reagent bottle 2 to collect the reagent, so as to avoid the sample needle 41 failing to absorb the reagent. In other words, the preset distance moved by the sample needle 41 changes in a negative correlation trend with the amount of reagent in the reagent bottle 2 detected by the reagent bottle detection component, so as to ensure that when the sample needle 41 absorbs the reagent, no waste of the reagent is caused, thereby improving the practicality of the reagent bottle support component 1.
[0054] Furthermore, the reagent bottle detection component is also used to detect the distance between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11, such as Figure 1The distance H shown, wherein the preset distance is positively correlated with the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 detected by the reagent bottle detection component. Specifically, the preset distance moved by the sample needle 41 is approximately positively correlated with the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 detected by the reagent bottle detection component.
[0055] As described above, the forces acting on the elastic member 12 when compressed include the gravity of the reagent bottle 2 and the force of the reagent bottle 2 moving away from the sample needle 41 . When the sample needle 41 does not contact the bottom of the reagent bottle 2 , the elastic member 12 is only compressed by the gravity of the reagent bottle 2 .
[0056] Therefore, when the reagent bottle 2 is loaded with reagent and placed on the reagent bottle mounting seat 11, the elastic member 12 is compressed. After the sample needle assembly completes collecting the reagent in the reagent bottle 2, the reagent in the reagent bottle 2 decreases, that is, the gravity of the reagent bottle 2 decreases, and the elastic member 12 stretches, driving the reagent bottle 2 to move away from the reagent bottle mounting seat 11, and the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 detected by the reagent bottle detection assembly increases.
[0057] Among them, if the reagent bottle 2 is located at the same position, and the sample needle 41 moves a preset distance based on the amount of reagent in the reagent bottle 2 to collect the reagent, when the remaining amount of reagent in the reagent bottle 2 is insufficient, the sample needle 41 needs to move a larger distance to collect the reagent. Since the compression of the elastic member 12 is related to the reagent in the reagent bottle 2, under the action of the elastic member 12, when the reagent in the reagent bottle 2 decreases, the elastic member 12 will stretch to make the reagent bottle 2 rise. At this time, part of the distance moved by the sample needle 41 is replaced by the distance that the elastic member 12 lifts the reagent bottle 2, and the distance that the sample needle 41 needs to move is reduced. That is, when the reagent in the reagent bottle 2 decreases, the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 becomes larger, and the preset distance that the sample needle 41 moves can be appropriately smaller than the preset distance that needs to be moved in theory.
[0058] Specifically, when the sample needle 41 collects reagent from the reagent bottle 2 last time, the reagent liquid level in the reagent bottle 2 drops by 0.2 mm. If there is no elastic member 12, the sample needle 41 should move 0.2 mm more than the previous time to absorb the reagent in the reagent bottle 2 during the next sampling. Since the amount of reagent in the reagent bottle 2 decreases, the reagent bottle 2 rises under the action of the elastic member 12. In one embodiment, the reagent bottle 2 may rise by 0.2 mm, and then the liquid level in the reagent bottle 2 rises by 0.2 mm, that is, the liquid level in the reagent bottle 2 is consistent with the liquid level in the reagent bottle 2 last time, and the sample needle 41 only needs to move the same preset distance as the previous distance to collect the reagent.
[0059] In another embodiment, the reagent bottle 2 may also rise by 0.1mm, and then the liquid level in the reagent bottle 2 rises by 0.1mm, that is, although the liquid level in the reagent bottle 2 is 0.2mm lower than the liquid level in the previous reagent bottle 2, due to the effect of the elastic member 12, the liquid level in the reagent bottle 2 is only 0.1mm lower than the liquid level in the previous reagent bottle 2, and the sample needle 41 only needs to move 0.1mm more than the previous distance to collect the reagent. In other embodiments, the reagent bottle 2 may also rise to other heights, and the height of the reagent bottle 2 rise is related to the elastic force of the elastic member 12, and the present application does not limit this.
[0060] In summary, due to the presence of the elastic member 12 , part of the moving distance of the sample needle 41 is replaced by the distance that the elastic member 12 lifts the reagent bottle 2 , so the preset moving distance of the sample needle 41 can be appropriately smaller than the preset distance that needs to be moved theoretically.
[0061] The present embodiment proposes to detect the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 by means of a reagent bottle detection component to set the preset distance for the sample needle 41 to move, and taking into account the relationship between the liquid level of the reagent in the reagent bottle 2 and the change in the reagent amount, that is, the elastic member 12 can raise the reagent liquid level in the reagent bottle 2 to be consistent with the reagent liquid level in the reagent bottle 2 before the reagent is collected, or the elastic member 12 can only raise the reagent bottle 2 a certain distance, and at this time the reagent liquid level in the reagent bottle 2 is still lower than the reagent liquid level in the reagent bottle 2 before the reagent is collected. Therefore, the preset distance for the sample needle 41 to move and the distance H between the bottom of the reagent bottle 2 and the bottom of the reagent bottle mounting seat 11 detected by the reagent bottle detection component show an approximately positive correlation trend.
[0062] Among them, since part of the moving distance of the sample needle 41 is replaced by the distance that the elastic member 12 lifts the reagent bottle 2, the preset distance that the sample needle 41 moves can be appropriately smaller than the preset distance that needs to be moved theoretically, thereby saving the energy consumption of controlling the sample needle 41 for reagent collection and improving the practicality of the reagent bottle support assembly 1.
[0063] Alternatively, if Figure 2 As shown, the reagent bottle mounting seat 11 includes a plurality of side walls 113 and a bottom 114 to form an accommodating space 111, wherein the height of at least one side wall 113 is greater than half of the height of the reagent bottle 2, that is, it exceeds the center of gravity of the reagent bottle 2 to prevent the reagent bottle 2 from falling off the reagent bottle mounting seat 11. When the reagent bottle 2 is placed in the reagent bottle mounting seat 11, the outer wall of the reagent bottle 2 contacts the plurality of side walls 113, that is, the reagent bottle 2 can be placed just in the accommodating space without shaking in the accommodating space due to the excessive size of the accommodating space, thereby ensuring the safety of the reagent bottle 2 placed on the reagent bottle mounting seat 11.
[0064] In summary, in the reagent bottle support assembly 1 provided in the embodiment of the present application, the reagent bottle 2 is placed on a support plate 13 slidably connected to the reagent bottle mounting seat 11, and an elastic member 12 is provided between the support plate 13 and the reagent bottle mounting seat 11, allowing the reagent bottle 2 to move along the first direction X, and when the sample needle 41 contacts the bottom of the reagent bottle 2, it moves away from the sample needle 41, avoiding the sample needle 41 piercing the bottom of the reagent bottle 2 to cause the reagent to leak or the sample needle 41 to be damaged, thereby improving the safety of the reagent bottle 2 and the sample needle 41. After the sample needle 41 is away from the bottom of the reagent bottle 2, the reagent bottle 2 returns to the initial position, facilitating the sample needle 41 to collect the reagent again, thereby improving the efficiency of the sample needle 41 in collecting the reagent.
[0065] Moreover, the elastic member 12 can be compressed or stretched along with the amount of reagent in the reagent bottle 2. When the amount of reagent in the reagent bottle 2 decreases, the reagent bottle 2 is lifted along the first direction X, thereby reducing the moving distance of the sample needle 41 when collecting reagents, reducing energy consumption, improving the collection efficiency of the sample needle 41 for reagents, improving the practicality of the reagent bottle support assembly 1, and improving the user experience of the reagent bottle support assembly 1.
[0066] The present application also provides a detection device, such as Figure 3 and Figure 4 As shown, Figure 3 is a schematic structural diagram of the first embodiment of the detection device of the present application, Figure 4 Detection device A comprises a reagent bottle support assembly 1 , a main body 3 , a sample needle assembly 4 and a sample injection assembly 5 .
[0067] The reagent bottle mounting seat 11 of the reagent bottle support assembly 1 is arranged on the sampling assembly 5 or in the main body 3, and the sample needle assembly 4 is arranged on the main body 3, which is used to collect reagents from the reagent bottle 2 in the reagent bottle support assembly 1. The sampling assembly 5 is used to transport samples to the main body 3, and the main body 3 is used to detect the samples.
[0068] Specifically, the sample injection assembly 5 and the main body 3 may be spaced apart, and the sample injection assembly 5 may deliver the sample to the main body 3. In one embodiment, the reagent bottle mounting seat 11 is directly disposed in the main body 3, and the sample needle assembly 4 may move quickly to the reagent bottle mounting seat 11 to collect the reagent in the reagent bottle 2, and the main body 3 uses the reagent collected by the sample needle assembly 4 and the sample delivered by the sample injection assembly 5 to perform sample detection. In another embodiment, the reagent bottle mounting seat 11 may also be disposed on the sample injection assembly 5 and disposed close to the main body 3, and the sample needle assembly 4 may move to the reagent bottle mounting seat 11 to collect the reagent in the reagent bottle 2.
[0069] In other embodiments, the reagent bottle mount 11 can also be separately arranged between the main body 3 and the sampling assembly 5. On the premise that the sample needle assembly 4 can collect the reagent in the reagent bottle 2 on the reagent bottle mount 11, the present application does not limit the specific installation position of the reagent bottle mount 11.
[0070] Among them, the sample needle assembly 4 also includes a driving module (not shown in the figure), which is connected to the sample needle assembly 4, and the driving module is used to drive the sample needle assembly 4 to move in the horizontal and vertical directions. The reagent bottle support assembly 1 is arranged directly below the horizontal movement path of the sample needle assembly 4.
[0071] In one embodiment, the reagent stored in the reagent bottle 2 built into the reagent bottle support assembly 1 is a reticulin dye solution, and the driving module drives the sample needle assembly 4 to approach the reagent bottle support assembly 1 in the horizontal direction until the driving module drives the sample needle assembly 4 to move to the top of the reagent bottle support assembly 1, and then the driving module drives the sample needle 41 to enter the reagent bottle 2 on the reagent bottle support assembly 1 in the vertical direction downward to collect the reticulin dye solution. After the sample needle 41 completes the collection, the driving module drives the sample needle 41 to move upward in the vertical direction to leave the reagent bottle 2. In one embodiment, the driving module can further drive the sample needle assembly 4 to move away from the reagent bottle support assembly 1 in the horizontal direction, or, does not drive the sample needle assembly 4 to move in the horizontal direction, so that the sample needle assembly 4 stays just above the reagent bottle support assembly 1, so as to facilitate the next reagent collection operation of the sample needle assembly 4 on the reagent bottle 2.
