Description

Technical Field

[0001] The utility model relates to the field of laboratory equipment, and more specifically, to a strain packaging device and a strain packaging apparatus. Background Art

[0002] In routine biological experiments, precise inoculation of strains into target containers is a fundamental operation, and currently relies generally on manual addition of control containers one by one. However, this method has significant drawbacks: the operation process is cumbersome and time-consuming, especially inefficient when processing large numbers of samples, and is easily affected by human factors (such as hand tremors and operator fatigue), resulting in strain loading deviations, affecting the reproducibility and accuracy of experimental results. At the same time, manual placement in densely packed test tube racks is very prone to misplacement due to visual errors or mistakes, resulting in the strain being mistakenly added to non-target containers, causing the contaminated containers to lose their experimental value and must be discarded, resulting in waste of samples, reagents and time, and increased costs.

[0003] Considering the above reasons, how to batch-package the strains is exactly the issue considered in this application. Utility Model Content

[0010] According to a further optimization of the present invention, a receiving groove for receiving the strain is provided on the upper surface of the connecting portion, and one side of the receiving groove is connected to the placement layer through an upwardly inclined slope.

[0011] In a further optimization of the present invention, baffles are provided on the sides of the containing groove and the placement layer to prevent the bacteria from escaping.

[0012] A strain dispensing device comprises a positioning seat, a receiving bottle and a strain dispenser. The positioning seat is provided with a groove for accommodating the receiving bottle.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0025] Reference Figure 1-5 As shown, a strain dispensing device 1 includes a dispensing device 1, and the dispensing device 1 includes a placement layer 11, a barrier layer 12 and an alignment layer 13;

[0026] The placement layer 11, the alignment layer 13 and the barrier layer 12 are all provided with a plurality of through holes 14;

[0027] The blocking layer 12 is staggered with the through holes 14 of the placement layer 11 and the alignment layer 13, and is used to prevent the strains on the placement layer 11 from falling onto the alignment layer 13. When the blocking layer 12 is moved so that its through holes 14 correspond to the through holes 14 of the blocking layer 12 and the alignment layer 13, the strains pass through the placement layer 11, the blocking layer 12 and the alignment layer 13 in sequence.

[0028] Reference Figure 1-2 As shown, when the through holes 14 of the blocking layer 12 are misaligned with the through holes 14 of the placement layer 11 and the alignment layer 13, the blocking layer 12 blocks the strains on the placement layer 11 from falling freely, preventing the strains from accidentally entering the alignment layer 13. When subpackaging is required, the blocking layer 12 is moved so that its through holes 14 correspond to the through holes 14 of the placement layer 11 and the alignment layer 13, so that the strains fall through the through holes 14 of the three layers in sequence under the action of gravity, thereby realizing batch subpackaging and eliminating the human error caused by manual filling of strains. After the operation is completed, the blocking layer 12 is moved in the opposite direction to reset to the misaligned state, blocking the falling path again. At the same time, the number of through holes 14 is set to multiple, and filling is achieved by moving the blocking layer 12.

[0029] Preferably, the dispenser 1 is provided with a connecting portion 15, and the placement layer 11 and the alignment layer 13 are both connected to the connecting portion 15. A spring 16 is provided between the barrier layer 12 and the connecting portion 15, and the barrier layer 12 is connected to the connecting portion 15 through the spring 16. The spring 16 is used to help the barrier layer 12 move and reset, so that the barrier layer 12 is misaligned with the through holes 14 of the placement layer 11 and the alignment layer 13.

[0030] Reference Figure 1-2 As shown, the user applies force to move the blocking layer 12 to compress the spring 16 so that its through hole 14 corresponds to the placement layer 11 and the through hole 14 of the alignment layer 13, and the strain falls freely. After the user stops applying force, the spring 16 elastically resets and pushes the blocking layer 12 to move in the opposite direction to the original misaligned position, automatically blocking the connection of the through hole 14. The expansion and contraction direction of the spring 16 is parallel to the movement direction of the blocking layer 12, ensuring a stable reset trajectory, simplifying the user's operating steps during filling, and improving the packaging efficiency.

[0031] Preferably, a guide post 17 is provided on one side of the barrier layer 12 corresponding to the connecting portion 15 , and the spring 16 is sleeved on the guide post 17 . The guide post 17 is used to guide the movement of the barrier layer 12 .

[0032] Reference Figure 1-2 As shown, in one embodiment, one end of the guide post 17 is fixedly connected to the connecting portion 15 and is sleeved with a spring 16. The barrier layer 12 may be provided with a guide groove that cooperates with the guide post 17. The other end of the guide post 17 is inserted into the guide groove to guide the barrier layer 12 to move along the trajectory of the guide post 17.

[0033] At the same time, another embodiment can also be provided with a guide ring on the barrier layer 12 that cooperates with the guide post 17. The guide ring is sleeved on the guide post 17. When the barrier layer 12 moves, the guide ring compresses the spring 16. Similarly, the guide post 17 can guide the barrier layer 12 to move along the track of the guide post 17.

[0034] When the barrier layer 12 moves, the guide column 17 limits the spring 16 to expand and contract only along its axial direction, preventing the spring 16 from bending and causing displacement during resetting. When the spring 16 expands and contracts along the guide column 17, the side wall of the guide column 17 contacts the inner wall of the spring 16 and provides support, ensuring the linear movement of the barrier layer 12 and avoiding the misalignment and failure of the through hole 14.

[0035] Preferably, a receiving groove 18 for receiving the strain is provided on the upper surface of the connecting portion 15 , and one side of the receiving groove 18 is connected to the placement layer 11 via an upwardly inclined slope.

[0036] Reference Figure 1-2 As shown, several strains are temporarily stored in the receiving groove 18. When they need to be packaged, the packaging device 1 is shaken to make the strains roll into the through holes 14 on the placement layer 11, and the remaining strains return to the receiving groove 18 along the slope. The blocking layer 12 is moved to make the strains fall into the holding bottle 3. Repeating the operation can quickly fill the placement layer 11 with strains. At the same time, the slope is relatively small, which makes it easier for the strains in the receiving groove 18 to roll smoothly along the slope into the through holes 14 of the placement layer 11.

[0037] Preferably, baffles 19 are provided on the sides of the receiving groove 18 and the placement layer 11 to prevent the bacteria from escaping.

[0038] Reference Figure 1-2 As shown, the baffle 19 is fixedly installed on the edge of the receiving groove 18 and the placement layer 11 to form an enclosing structure to limit the activity range of the strain. When the strain is subjected to external force, the baffle 19 prevents it from escaping from the receiving groove 18 and the placement layer 11, preventing the strain in operation from escaping and causing environmental pollution and strain contamination.

[0039] A strain packaging device includes a positioning seat 2, a receiving bottle 3 and a strain dispenser 1. The positioning seat 2 is provided with a groove 21 for accommodating the receiving bottle 3. The receiving bottle 3 is installed in the groove 21 and is used to accommodate strains dropped from the alignment layer 13. The strain dispenser 1 adopts the above-mentioned strain dispenser 1, and the through hole 14 on the alignment layer 13 of the strain dispenser 1 is used to cooperate with the bottle mouth of the receiving bottle 3 to allow the strain to enter the receiving bottle 3.

[0040] Reference Figure 1 and Figure 5 As shown, the strain dispenser 1 is moved above the positioning seat 2, and the through hole 14 of the alignment layer 13 is facing the bottle mouth of the receiving bottle 3 to ensure that the strain falls into the receiving bottle 3. After passing through the through hole 14 of the alignment layer 13, the strain directly enters the receiving bottle 3, reducing human errors (such as misplacement caused by visual errors). The inner wall of the groove 21 matches the shape and size of the outer wall of the receiving bottle 3 to ensure that the bottle body does not shake.

[0041] Preferably, the packaging device further comprises a base 4 , on which a limiting member 41 is provided. The positioning seat 2 is mounted on the base 4 , and the limiting member 41 is used to interfere with the connecting portion 15 to help the strain packaging device 1 to be quickly positioned.

[0042] Reference Figure 1 and Figure 3 As shown, the limiting member 41 is installed on the base 4. When the edge of the strain dispenser 1 conflicts with the limiting member 41, the through hole 14 of the alignment layer 13 is automatically aligned with the bottle mouth of the receiving bottle 3, so that the strain can be accurately dropped into the receiving bottle 3. When refilling, the strain dispenser 1 is removed, shaken and refilled, and then moved again to conflict with the limiting member 41, thereby achieving rapid positioning, reducing the time spent on manual calibration, and improving efficiency.

[0043] Preferably, a fixing groove 42 is provided on the base 4 , and the positioning seat 2 is installed on the fixing groove 42 , and the shape of the fixing groove 42 is adapted to the positioning seat 2 .

[0044] Reference Figure 3 and Figure 4The positioning seat 2 and the fixing groove 42 can adopt an interference fit to reduce the displacement of the positioning seat 2 and realize a quick installation and disassembly process. After the strain dispenser 1 is filled with strains in several receiving bottles 3, the positioning seat 2 is removed, driving several filled receiving bottles 3 to move at the same time, and the positioning seat 2 and the receiving bottles 3 that are not filled with strains are reinstalled, and the positioning seat 2 is embedded in the fixing groove 42, thereby reducing the steps of fast batch filling of strains and improving the filling efficiency. At the same time, an anti-slip pad can be added to the bottom surface of the base 4 to increase the stability of the base 4. At the same time, the groove 21 can also be set to an inverted trapezoid to facilitate the embedding of the positioning seat 2.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
