[0026] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The utility model provides a sample adding plate auxiliary device, which is used to assist the sample adding needle to add samples in the sample adding hole of the sample adding plate. In one embodiment, please refer to Figure 1 and Figure 2 The auxiliary device includes an auxiliary frame 1 and a shielding member 2. The auxiliary frame 1 can be installed on the sample loading plate. The auxiliary frame 1 is provided with a through hole 13 for the needle of the sample loading needle to pass through at the position corresponding to each sample loading hole of the sample loading plate. The needle of the sample loading needle can pass through the through hole 13 to load the sample to the sample loading hole where the sample needs to be loaded.

[0030] The shielding member 2 is movably arranged on the auxiliary frame 1. The shielding member 2 is provided with a plurality of through holes 23 that can be connected with the through holes 13. The through holes 23 can be connected with the through holes 13 by moving the shielding member 2. When a sample is to be added to a sample well, the shielding member 2 is driven to move the corresponding through hole 23 to be connected with the sample well. It should be noted that the size of the through hole 23 is preferably less than or equal to the size of the sample well. In this case, the structure of the shielding member 2 surrounding the through hole 23 can cover the sample well except the part connected with the through hole 23.

[0031] By setting the auxiliary frame 1 and the shielding member 2, the shielding member 2 is moved before adding samples to the sample adding plate, and the through hole 23 on the shielding member 2 is connected with the sample adding hole to be added. In this way, it can play a role of identification. The position of the sample adding hole to be added can be quickly distinguished through the position of the through hole 23 on the shielding member, and there is no need to spend a long time to find and confirm the position of the sample adding hole, and it can also avoid adding samples due to mixing up the positions of the sample adding holes and causing sample adding errors, which is beneficial to saving time and facilitating accurate sample adding.

[0032] It is worth mentioning that the sizes of the sample addition hole, the perforation 13 and the through hole 23 can be reduced in sequence, or the sizes of the perforation 13 and the through hole 23 are equal and both are smaller than the size of the sample addition hole. This arrangement can make it difficult for the needle to hit the hole wall of the sample addition hole when the perforation 13 and the through hole 23 are connected and the needle of the sample addition needle is inserted into the sample addition hole for sample addition, and it is difficult to add more or less, thereby ensuring the accuracy of sample addition.

[0033] In one embodiment, see Figure 1 and Figure 2The shielding member 2 includes a first baffle 21 and a second baffle 22. Part of the structure of the first baffle 21 overlaps with part of the structure of the second baffle 22, and a through hole 23 is provided between the overlapping structures of the first baffle 21 and the second baffle 22. The area of ​​the through hole 23 is smaller than the overlapping area. The shape of the through hole 23 is not limited and may be a round hole or a square, etc.

[0034] Preferably, the middle portion of the first baffle 21 and the middle portion of the second baffle 22 are overlapped and connected together, and there is a certain angle between the two baffles.

[0035] More preferably, the two baffles are arranged at a right angle, and the middle parts of the two baffles are integrally formed.

[0036] In a specific embodiment, only one through hole 23 may be provided between the two baffles, that is, located at the overlapping portion of the first baffle 21 and the second baffle 22. Of course, if multiple sample loading holes are loaded at one time, multiple through holes 23 may be provided at intervals on the first baffle 21, and the center distance between two adjacent through holes 23 is equal to the center distance between two adjacent through holes 13, and is also equal to the center distance between two adjacent sample loading holes.

[0037] Not only can a plurality of through holes 23 be provided on the first baffle plate 21, but a plurality of through holes 23 can also be provided at intervals on the second baffle plate 22, or a plurality of through holes 23 can be provided at intervals on both the first baffle plate 21 and the second baffle plate 22. It should be noted that, regardless of whether the through holes 23 are provided on the first baffle plate 21 or the second baffle plate 22, they are all symmetrically provided with respect to the through holes 23 located at the overlapping portion of the two baffle plates, that is, when the first baffle plate 21 and the second baffle plate 22 are both provided with a plurality of through holes 23, these through holes 23 are arranged in a "cross" shape.

[0038] In a specific embodiment, if a plurality of through holes 23 are provided on the first baffle plate 21 and the second baffle plate 22, but when adding samples, it is not necessary for each through hole 23 to be connected to the corresponding sample adding hole, that is, so many through holes 23 may not be used in actual application. At this time, it is necessary to cover the unnecessary through holes 23 to avoid interfering with the sample adding personnel.

[0039] In this embodiment, a slide plate 25 is provided on the first baffle plate 21 and / or the second baffle plate 22. If only the first baffle plate 21 is provided with a plurality of through holes 23, the slide plate 25 is provided only on the first baffle plate 21; if only the second baffle plate 22 is provided with a plurality of through holes 23, the slide plate 25 is provided only on the second baffle plate 22; if both the first baffle plate 21 and the second baffle plate 22 are provided with a plurality of through holes 23, the slide plates 25 are provided on both baffle plates.

[0040] Specifically, no matter whether the slide plates 25 are arranged on the first baffle plate 21 or the second baffle plate 22 , the slide plates 25 can cover all the through holes 23 , and the through holes 23 can be exposed by sliding the slide plates 25 .

[0041] The following is an example of setting a slide plate 25 on the first baffle plate 21. A slide groove 24 is provided on the first baffle plate 21 along the arrangement direction of the through holes 23. The slide groove 24 is connected to the through holes 23. The shape and size of the slide plate 25 are adapted to the shape and size of the slide groove 24, so that the slide plate 25 can be inserted into the slide groove 24 to cover the through holes 23.

[0042] Preferably, two independent slide plates 25 are provided on the first baffle plate 21, and the two slide plates 25 are located in the same slide groove 24 and can move independently. In this way, the covering effect of the slide plate 25 is more flexible, and the two slide plates 25 cooperate to more conveniently expose any one or several through holes 23 on the first baffle plate 21.

[0043] For more details, please refer to Figure 4 The two side walls of the slide groove 24 have a limiting portion 241 opened along the path of the slide groove 24, and the slide plate 25 can be inserted into the slide groove 24, and the slide plate 25 is provided with a limiting end 251 at the position corresponding to the limiting portion 241, and the limiting end 251 can be inserted into the limiting portion 241, so that the slide plate 25 is not easy to be separated from the slide groove 24. It should be noted that the friction coefficient between the limiting portion 241 and the limiting end 251 needs to be set slightly larger, so that the slide plate 25 is not too easy to slide in the slide groove 24, so as to avoid the slide plate 25 from sliding randomly in the slide groove 24, and then avoid the inaccurate exposure of the through hole 23 due to the position deviation of the slide plate 25.

[0044] It is worth mentioning that when the sliding plate 25 is provided on the second baffle plate 22, it is consistent with the first baffle plate 21, and will not be described in detail here.

[0045] In one embodiment, please refer to Figure 3 The first baffle plate 21 and the second baffle plate 22 can move in the first direction and the second direction relative to the auxiliary frame 1. A positioning pin 121 is provided on the auxiliary frame 1 on the moving path of the first baffle plate 21 and the second baffle plate 22. The first baffle plate 21 and the second baffle plate 22 are provided with a positioning groove 260 corresponding to the position of the positioning pin 121, and the positioning pin 121 can be inserted into the positioning groove 260.

[0046] Each perforation 13 on the auxiliary frame 1 is connected to a corresponding sample loading hole, which makes the arrangement of the perforations 13 consistent with that of the sample loading holes. In this embodiment, the sample loading holes are arranged in a matrix, and the perforations 13 are also arranged in a matrix accordingly. The first direction and the second direction are the horizontal direction and the vertical direction of the arrangement of the perforations 13, respectively, with respect to the arrangement of the perforations 13. Please refer to the figure, the X direction shown in the figure is the first direction, and the Y direction shown in the figure is the second direction.

[0047] It should be noted that the auxiliary frame 1 includes an upper frame 11 and a lower frame 12 that are spaced apart, the upper frame 11 and the lower frame 12 have the same shape and size, the edges of the upper frame 11 and the lower frame 12 are fixedly connected by screws, and the upper frame 11 and the lower frame 12 are arranged opposite to each other when connected. The first baffle 21 and the second baffle 22 are movably arranged in the movable space between the upper frame 11 and the lower frame 12.

[0048] The upper frame 11 and the positions of the frames corresponding to the sample adding holes are both provided with perforations 13, and the upper frame 11 and the lower frame 12 are transparently provided. By making the upper frame 11 and the lower frame 12 transparent, it is convenient to observe the sample adding situation.

[0049] The lower frame 12 is located between the upper frame 11 and the sample loading plate, and a positioning pin 121 is provided at the edge of the lower frame 12. As shown in the figure, the upper frame 11 and the lower frame 12 are preferably square, and the two long sides and two wide sides of the lower frame 12 are respectively parallel to the first direction and the second direction, and the positioning pins 121 are provided on the two long sides and two wide sides of the lower frame 12. The spacing between two adjacent positioning pins 121 is equal to the center spacing between two adjacent sample loading holes.

[0050] A positioning groove 260 is provided at the center position of the first baffle 21 and the second baffle 22 toward one end of the lower frame 12. By providing the positioning pin 121 and the positioning groove 260, when the positions of the first baffle 21 and the second baffle 22 need to be stabilized, the positioning pin 121 can be inserted into the positioning groove 260. When the first baffle 21 and the second baffle 22 need to be moved, the positioning pin 121 can be disengaged from the positioning groove 260 by lifting the two baffles. In this way, when the two baffles are moved to the point where the through hole 23 is connected to the corresponding through hole 13, the cooperation of the positioning pin 121 and the positioning groove 260 stabilizes the positions of the two baffles and makes them less likely to shift, thereby ensuring that the through hole 23 and the through hole 13 are not misaligned.

[0051] In addition, a sleeve portion 122 is provided at one end of the lower frame 12 facing away from the upper frame 11. The sleeve portion 122 can be sleeved on the sample adding plate to achieve the connection between the entire frame and the sample adding plate, which is also beneficial to avoid positional offset between the frame and the sample adding plate.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
