Description

Technical Field

[0001] The present invention relates to the technical field related to the storage of pharmaceuticals, and in particular, to a modular in vitro diagnostic reagent storage and protection box. Background Art

[0002] In vitro diagnostic reagents play an important role in modern medicine, and their accuracy and reliability directly affect the diagnosis and treatment effects of diseases. Therefore, it is crucial to ensure the quality and stability of in vitro diagnostic reagents during storage and transportation. The storage and protection box, as the main equipment for storing and transporting in vitro diagnostic reagents, has an irreplaceable role.

[0003] After retrieval, the publicly disclosed patent with publication number CN212638393U discloses a detection kit with a modular design that can accommodate reagent bottles of various specifications, including a box cover and a box body. It is characterized in that: partitions are arranged inside the box body, the partitions evenly divide the box body into multiple storage boxes, a second permanent magnet is arranged on the inner wall of the box body, a detachable mounting plate is installed in the storage box, the mounting plate is provided with a first permanent magnet for attracting the second permanent magnet, and mounting grooves for accommodating reagent bottles are formed on the mounting plate.

[0004] Currently, by replacing specific mounting plates, it is possible to store multiple different types of reagent tubes in the box body simultaneously. However, this solution has significant limitations. Since the opening size of the mounting groove is fixed, whenever it is necessary to store reagent tubes of different specifications or types, the entire mounting plate must be frequently replaced. This not only increases the complexity of the operation but also leads to a series of problems in practical applications. Specifically, in order to meet the storage requirements of different reagent tubes, laboratories often need to prepare multiple sets of mounting plates of different specifications as spares. However, in the actual application process, most of these spare mounting plates are often idle, resulting in a waste of resources and occupation of storage space. In addition, frequently replacing the mounting plate also increases the time cost and reduces the work efficiency. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0038] Example 1, please refer to Figure 2 and Figure 3 It can be seen that two storage modules are symmetrically arranged inside the box body 1, and the storage module is mainly used for storing reagent tubes. A storage cavity 1001 is reserved between the two storage modules, and the storage cavity 1001 can store some commonly used tools. Such as Figure 1As shown in the figure, the top of the box body 1 can be fixed with a box cover 2 through the box buckles on both sides. By using the box cover 2 to cover and protect the opening at the top of the box body 1, the reagent tubes placed inside the box body 1 can be effectively protected. Moreover, the number of box bodies 1 is not limited to one. Multiple box bodies 1 can be connected end to end vertically by using lock buckles, so as to provide more storage modules. A card slot is correspondingly arranged on the side of each box body 1. By the operator putting the corresponding card into it, it is convenient to know the type and use of the reagent tubes contained in the box body 1.

[0039] For the storage module, there is a general clamping plate 3 which is the core component of the storage module. Figure 2 and Figure 5 It can be seen that a number of equally spaced placement grooves 300 are formed on the surface of the general clamping plate 3. The surface shape of the placement grooves 300 is a combination of a rectangle and a triangle. By using the placement grooves 300, the position of the reagent tubes can be limited, so that they can be placed in an orderly manner in the box body 1, avoiding the problem of reagent tube accumulation. Moreover, there is a guiding and restricting block on the side of the general clamping plate 3 which is fixedly connected by bolts. Correspondingly, Figure 2 and Figure 3 It can be seen that a dovetail-shaped guiding frame is fixedly installed on the inner side wall of the box body 1. The guiding and restricting block and the dovetail-shaped guiding frame cooperate to ensure that when the general clamping plate 3 is put into the storage module, it can only move up and down reciprocally in one direction. Figure 6 and Figure 12 It can be seen from that an adjusting ejector rod slide seat 7 is movably installed on the inner side of the general clamping plate 3 by using a dovetail groove guide, and the adjusting ejector rod slide seat 7 can only move along the inside of the general clamping plate 3. There is an adjusting distance frame 14 on the surface of the adjusting ejector rod slide seat 7 which is fixedly connected by bolts. Figure 6 It can be seen that the adjusting distance frame 14 is built by a cross bar and multiple vertical bars. One end of a vertical bar is fastened to the adjusting ejector rod slide seat 7 by bolts, so as to realize that the adjusting ejector rod slide seat 7 can drive the adjusting distance frame 14 to move horizontally. When the adjusting distance frame 14 moves to the right, the vertical bars in the adjusting distance frame 14 are relatively close to the triangle of the placement groove 300. By using the inner included angle of the triangle and the restriction of the adjusting distance frame 14, the actual usable notch size of the placement groove 300 is restricted, so as to realize the storage of reagent bottles with different diameters.

[0040] There is a wedge-shaped guiding frame 6 on the inner side wall of the box body 1 which is fixedly connected by bolts on one side of the adjusting ejector rod slide seat 7. Figure 10 and Figure 11 It can be seen that the side of the wedge-shaped guiding frame 6 is a smooth inclined plane. When the general clamping plate 3 moves vertically downward by using the dovetail-shaped guiding frame, the adjusting ejector rod slide seat 7 moves synchronously downward along the inclined plane on the side of the wedge-shaped guiding frame 6. Figure 11 It can be seen that the adjusting ejector rod slide seat 7 following the general clamping plate 3 downward will tend to retract into the general clamping plate 3 when blocked by the wedge-shaped guiding frame 6.Figure 12 It can be clearly seen that when the ejector rod slider 7 is adjusted to drive the distance adjustment frame 14 to move to the right, the vertical rod of the distance adjustment frame 14 can move to the right, thereby changing the actual working size of the placement groove 300. Thus, it can be seen that in the first embodiment, by changing the actual downward height of the universal clamping plate 3, the notch size of the actual working placement groove 300 can be changed. By adjusting the actual height of the installation of the universal clamping plate 3 in each storage module, it is possible to store reagent tubes with different outer diameters. Moreover, the universal clamping plate 3 described in the first embodiment has universality, and any universal clamping plate 3 can be installed and used in the storage box, thereby avoiding the problem of idleness due to the inappropriate notch of the placement groove 300.

[0041] After the universal clamping plate 3 is adjusted, the notch of the corresponding placement groove 300 that can be actually applied is also relatively determined. In order to always maintain the adjusted notch size, it is necessary to ensure that the universal clamping plate 3 always maintains the required position. Combining Figure 6 It can be seen that on the side of the universal clamping plate 3 that is relatively far from the adjusting ejector rod slider 7 and inside, there is a tooth row slider 9 movably installed by using a dovetail groove. A push spring 12 is arranged between the tooth row slider 9 and the adjusting ejector rod slider 7. Driven by the elastic force of the push spring 12, the adjusting ejector rod slider 7 and the tooth row slider 9 move relatively away. On the one hand, the adjusting ejector rod slider 7 extends outwards from the side of the universal clamping plate 3. On the other hand, the limit ejector rod 8 fixed to the side of the tooth row slider 9 extends out from the other side of the universal clamping plate 3. Combining Figure 2 、 Figure 4 、 Figure 10 and Figure 11 It can be seen that an adjusting rod 4 is movably installed in the middle of the inner side of the box body 1 and between two storage modules. An adjusting handwheel 401 is arranged at the top of the adjusting rod 4, and an operator can drive the adjusting rod 4 to rotate by using the adjusting handwheel 401. From Figure 4 It can be seen that a plurality of equally spaced ring frames are fixedly installed on the side of the adjusting rod 4. When the limit ejector rod 8 is inserted between two ring frames, its up and down movement can be restricted. On this basis, in order to facilitate the installation and disassembly of the universal clamping plate 3, combining Figure 4 It can be seen that an increasing distance arc block 400 is fixedly installed on the side of the adjusting rod 4. The outer side of the increasing distance arc block 400 is arc-shaped. Moreover, a reset groove 402 is opened in the middle of the outer side of the increasing distance arc block 400. The reset groove 402 is a vertical rectangular groove. When the limit ejector rod 8 is inserted into the reset groove 402, the limit ejector rod 8 will not be blocked when moving up and down. Installation grooves 403 are opened on the side of the adjusting rod 4 and on the ring frames. Two symmetrically arranged installation grooves 403 are arranged on one ring frame. There is a step surface between the installation groove 403 and the side wall of the adjusting rod 4. When the limit ejector rod 8 moves downward and passes through the installation groove 403, it is necessary to overcome the movement resistance brought by the step surface. Moreover, from Figure 12It can be seen that under normal conditions, the two limit ejector rods 8 respectively abut against the arc-shaped ends of the distance-increasing arc block 400, and there is a certain distance between the installation groove 403 and the arc-shaped ends of the distance-increasing arc block 400. This ensures that in the normal state of the adjusting rod 4, the limit ejector rod 8 and the installation groove 403 are relatively staggered. When the universal splint 3 is compressed or pulled, it cannot break away from the ring frame outside the adjusting rod 4, which also ensures that after the downward adjustment of the universal splint 3 is completed, it will not move up and down due to external forces under normal conditions.

[0042] In actual application, in the initial state, taking Figure 2 , Figure 4 and Figure 13 the left figure as an example, when installing the universal splint 3 on the right side, the adjusting rod 4 is driven by the adjusting handwheel 401 to rotate counterclockwise by a certain angle, so that the installation groove 403 on the right side corresponds to the limit ejector rod 8 on the right side. According to the cooperation of the guiding restriction block on the universal splint 3 and the dovetail-shaped guiding frame inside the box body 1, the universal splint 3 can move downward and be placed into the receiving module on the right side. During the downward movement of the universal splint 3, the adjusting ejector rod slide 7 moves downward synchronously along the wedge-shaped guiding frame 6. At the same time, the adjusting ejector rod slide 7 further approaches the placing groove 300 through the distance-adjusting frame 14, so as to change the size of the actual working notch of the placing groove 300. When the placing groove 300 in this receiving module is adjusted to the appropriate notch size, the adjusting rod 4 is driven by the adjusting handwheel 401 to rotate in the reverse direction, and then the universal splint 3 on the left side is installed in this way.

[0043] As Figure 12 shown, when the universal splints 3 on both the left and right sides are installed, the limit ejector rods 8 restricted by the elastic force of the push spring 12 will abut against the distance-increasing arc block 400, and the two limit ejector rods 8 finally abut against the arc-shaped ends of the distance-increasing arc block 400. The installation groove 403 and the limit ejector rod 8 are relatively staggered, ensuring that in the normal state of the universal splint 3, the end of the limit ejector rod 8 is relatively far away from the installation groove 403. In this state, even if the universal splint 3 is compressed and has a tendency to move downward, the limit ejector rod 8 cannot cross the ring frame outside the adjusting rod 4. Therefore, the universal splint 3 will always maintain the adjusted height. Regarding when the limit ejector rod 8 abuts against the outer arc of the distance-increasing arc block 400, referring to Figure 13 shown, at this time, the adjusting rod 4 has rotated counterclockwise by a certain angle relatively. The limit ejector rod 8 on the left abuts against the outer arc of the distance-increasing arc block 400. Since the limit ejector rod 8 always has a tendency to move outward under the elastic force of the push spring 12, when the limit ejector rod 8 abuts against the outer arc of the distance-increasing arc block 400, the adjusting rod 4 has a tendency to rotate clockwise under the guidance of the outer arc until the two limit ejector rods 8 both abut against the arc-shaped ends of the distance-increasing arc block 400.

[0044] Finally, when it is necessary to disassemble the general splint 3, rotate the adjustment rod 4 by 90 degrees by using the adjustment handwheel 401, which will directly align the reset channel 402 with the limit ejector rod 8. During this process, since the reset channel 402 cannot restrict the movement of the limit ejector rod 8, the adjustment ejector rod slide 7 pushed by the elastic force of the push spring 12 abuts against the inclined surface of the wedge-shaped guide frame 6, forcing the general splint 3 to tend to move upward until the adjustment ejector rod slide 7 abuts against the top of the inclined surface of the wedge-shaped guide frame 6, facilitating the operator to directly take out the general splint 3.

[0045] Embodiment 2 is a supplement to Embodiment 1. During the handling of the box body 1, phenomena such as shaking are inevitable. In order to effectively shock-proof and protect the reagent tubes placed in the placement groove 300, please refer to Figure 8 and Figure 10 It can be seen that a buffer assembly 5 is provided on the inner side of the box body 1. The buffer assembly 5 includes a guiding telescopic rod 502. A middle sleeve 500 is fixedly installed at the top of the guiding telescopic rod 502, and a buffer spring 503 that pushes the middle sleeve 500 upward is arranged on the outside. In practical applications, the guiding telescopic rod 502 is a telescopic rod with an elliptical cross-section, which can restrict the middle sleeve 500 to only move up and down reciprocally. A "C"-shaped shielding sleeve 501 is fixedly connected to the top of the middle sleeve 500. A buffer arm 504 that can reciprocate up and down along the central axis of the shielding sleeve 501 is movably installed on the outer side of the shielding sleeve 501. The buffer arm 504 is as Figure 13 shown in the right figure. The buffer arm 504 pushed by the elastic force of the buffer spring 503 is located at the bottom of the general splint 3 and is directly below the placement groove 300. Through the soft rubber pad fixed on the surface of the buffer arm 504, it can Figure 13 provide effective support for the reagent tube A in Figure 8 . The advantage of this Embodiment 2 is that, as Figure 10 shown, the buffer arm 504 can move up and down along the shielding sleeve 501. Under normal conditions, the buffer arm 504 is at the inner bottom of the shielding sleeve 501. Combining Figure 10 it can be seen that when the general splint 3 is installed in the storage module, its bottom will abut against the top of the shielding sleeve 501. Pushed by the shielding sleeve 501, it is restricted that there is always a certain distance between the bottom of the general splint 3 and the buffer arm 504, ensuring that the reagent tube A can be stably placed in the placement groove 300.

[0046] When this Embodiment 2 is applied, as Figure 9 shown, anti-collision cotton blocks 200 are provided at both the bottom of the box cover 2 and the box body 1. When the box cover 2 is closed on the top of the box body 1, as Figure 10As shown in the figure, the anti-collision cotton block 200 at the bottom of the box cover 2 will press against the top of the reagent tube A. When the reagent tube A is pressed, it will squeeze the buffer arm 504 at the bottom. The buffer arm 504 squeezes the buffer spring 503 through the middle sleeve 500, ensuring that the reagent tube A can be elastically clamped and avoiding the problem of the reagent tube A being broken due to impact during handling. It should be noted that when the reagent tube A in the second embodiment is placed, the reagent tubes A at the same height should be placed on the same buffer arm 504 to avoid the problem that the reagent tubes A on the buffer arm 504 cannot be effectively protected due to height differences.

[0047] From the above, it can be seen that the technical means proposed in the second embodiment can provide elastic buffering during the handling of the reagent tube A, thereby effectively protecting the reagent tube A.

[0048] Embodiment 3 is a further improvement based on Embodiment 2. It should be noted that Embodiment 2 can be implemented independently or in cooperation with Embodiment 3. Please refer to Figure 6 and Figure 7 As shown in the figure, a further limitation is made on the connection method of the push spring 12 in Embodiment 3. A transmission gear 110 meshing with the external teeth of the tooth row slide seat 9 is movably installed inside the general clamping plate 3. The rotating shaft of the transmission gear 110 is coaxially and firmly installed with a driving wheel 11. Therefore, when the transmission gear 110 rotates one circle, the driving wheel 11 also rotates one circle. When the tooth row slide seat 9 moves along the inner side of the general clamping plate 3, the meshing between the tooth row slide seat 9 and the transmission gear 110 can force the driving wheel 11 to rotate synchronously. The diameter value of the driving wheel 11 is 4 - 6 times the diameter value of the transmission gear 110. Moreover, a driven wheel 10 is movably installed inside the general clamping plate 3 on one side of the driving wheel 11. The driven wheel 10 and the driving wheel 11 are connected by annular belt drive. For actual selection, the annular belt can be a belt or a chain. Correspondingly, the driving wheel 11 / driven wheel 10 is a pulley / sprocket. The push spring 12 in Embodiment 3 is as Figure 3 shown. One end of the push spring 12 is fixed on the adjustment top rod slide seat 7, and the other end is firmly connected to the annular belt according to the bracket. Under the elastic push of the push spring 12, there is still a tendency for the adjustment top rod slide seat 7 and the limit top rod 8 to be pushed out from the side of the general clamping plate 3.

[0049] On this basis, as Figure 5 and Figure 6As shown, there is a magnet 13 fixedly installed on the side of the annular belt by a bracket, and the magnet 13 can move synchronously with the annular belt. A magnetic through groove 301 coaxially aligned with the shielding sleeve 501 is provided on the surface of the general clamping plate 3. The diameter of the magnetic through groove 301 is relatively smaller than that of the shielding sleeve 501, and a metal column 505 is fixedly installed at the end of the buffer arm 504. When the magnet 13 moves to the magnetic through groove 301, the magnetism of the magnet 13 can pass through the magnetic through groove 301 to adsorb the corresponding metal column 505 below. In order to prevent the magnet 13 from magnetically adsorbing adjacent metal columns 505, during the manufacturing process, both the shielding sleeve 501 and the general clamping plate 3 are made of magnetic shielding materials, which can avoid the adjacent metal columns 505 being accidentally attracted by the magnet 13.

[0050] In the third embodiment, when the general clamping plate 3 is pressed downward to adjust the notch spacing of the placement groove 300, the method is the same as that described in the first embodiment, and will not be elaborated here.

[0051] When it is necessary to take out the reagent tube A in the placement groove 300, combining Figure 4 and Figure 13 It can be seen that by using the adjustment handwheel 401 to make the adjustment rod 4 deflect counterclockwise, the outer arc of the distance increasing arc block 400 will abut against the left limiting ejector rod 8 and retract it into the general clamping plate 3. During this process, the moving tooth row slider 9 can make the driving gear 110 meshing with it drive the driving wheel 11 to rotate clockwise. On the one hand, the bracket on the annular belt will shorten the distance from the adjustment ejector rod slider 7, so that the push spring 12 is further compressed; on the other hand, the annular belt will drive the magnet 13 to move to the right. Due to the large diameter difference between the driving wheel 11 and the driving gear 110, when the driving gear 110 is slightly deflected under the influence of the meshing of the tooth row slider 9, the driving wheel 11 can drive the annular frame to move a large displacement until the magnet 13 passes through the magnetic through groove 301. At this time, the metal column 505 attracted by the magnetism will lift the corresponding buffer arm 504 upward, as Figure 13 shown on the right. When the buffer arm 504 is lifted upward, it will further lift the reagent tube A placed on the buffer arm 504. The reagent tube A lifted by the buffer arm 504 protrudes relatively, and when the operator takes it, it will not touch the adjacent reagent tube A, which is convenient for the operator to take. As the adjustment rod 4 continues to rotate counterclockwise, the magnet 13 will also continue to move to the right, so as to pass through the corresponding magnetic through grooves 301 in turn, ensuring that the operator can easily take out the placed reagent tube A.

[0052] Moreover, referring to Figure 4 、 Figure 6 and Figure 14It can be seen that when the adjusting rod 4 rotates to near ninety degrees, the magnetic block 13 will abut against the distance adjusting frame 14 and push it further to the right. If the reagent tube A is placed in the placement groove 300, the distance adjusting frame 14 will be blocked by the reagent tube A, restricting the movement of the distance adjusting frame 14. The adjusting rod 4 will also be unable to rotate, and the limit ejector rod 8 will ultimately not enter the reset channel 402. Finally, when there is a reagent tube A in the placement groove 300, the adjusting rod 4 cannot rotate ninety degrees, and thus the retraction of the universal splint 3 cannot be achieved. Similarly, when the reagent tube A in the placement groove 300 has been completely removed, the adjusting rod 4 can rotate to ninety degrees and abut against the reset channel 402 through the limit ejector rod 8. After that, the adjusting ejector rod slider 7 abuts against the inclined surface of the wedge-shaped guide frame 6 to drive the universal splint 3 to move upward, facilitating the removal of the universal splint 3.
