Description

Technical Field

[0001] The invention relates to the technical field of nest boards, and in particular to a nest board. Background Art

[0002] In the pharmaceutical field, the storage and transportation of needle-free prefilled drug cores is an important technical issue. The traditional nest plate design has some limitations, especially in terms of stability and adaptability of the fixed drug core. The shaking and deviation of the drug core in the nest plate may cause safety hazards during transportation or operation, and also affect the efficiency and accuracy of the use of the drug core.

[0003] Existing nest plate designs usually do not have sufficient fixing capabilities and cannot effectively prevent the drug core from moving in the nest plate. This design deficiency, especially when the drug core needs to be frequently moved or transported, can cause damage or failure of the drug core, increasing the risk of drug production and use.

[0004] In addition, existing nest plate designs often lack elastic clamping functions, which means they cannot adapt to different specifications or shapes of drug cores. This limitation restricts the versatility and flexibility of the nest plate, forcing pharmaceutical manufacturers to design and manufacture multiple nest plates for different specifications of drug cores, increasing production costs and complexity. Summary of the invention

[0005] In view of the above problems existing in the existing nest boards, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a nest plate, which aims to provide a nest plate that can better fix the core, reduce shaking and deviation, and improve safety during transportation and operation. At the same time, the nest plate design of the present invention also has an elastic clamping effect, can adapt to cores of different specifications or shapes, and improve the versatility and flexibility of the nest plate.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: a nest plate, comprising a plate body component and a plurality of limiting components distributed on the plate body component, wherein the limiting components are composed of a plurality of clips and are configured as a bud as a whole.

[0008] As a preferred solution of the nesting plate of the present invention, each of the clips of the same limiting component is arranged to be inclined inward, and a plurality of the clips gradually gather from the fixed end to the free end to form a bud shape.

[0009] As a preferred solution of the nest plate of the present invention, the free end of the clip is provided with an inward clip hook portion, the clip hook portion consists of a first surface distributed at an obtuse angle to the inner side surface of the clip, a second surface connected to the lower surface of the clip, and a third surface is provided between the first surface and the second surface.

[0010] As a preferred solution of the nesting plate of the present invention, the plate body part includes a rectangular annular upper edge and a rectangular bottom surface, and a circle of side walls is arranged between the upper edge and the bottom surface to form the rectangular groove-shaped plate body part.

[0011] As a preferred solution of the nesting plate of the present invention, a plurality of holes are opened on the bottom surface, the plurality of holes are distributed in a rectangular shape, and are staggered between two adjacent rows.

[0012] As a preferred solution of the nesting plate of the present invention, the limiting component is arranged in the hole, and the clips of the limiting component are arranged in the hole at equal intervals on a circle.

[0013] As a preferred solution of the nest plate of the present invention, two inwardly recessed grooves are arranged on the plate body component, the two grooves are located on two opposite surfaces of the plate body component, and the two grooves are staggered.

[0014] As a preferred solution of the nesting plate of the present invention, symmetrical protrusions are arranged at each corner of the upper edge, and the protrusions are located on the side of the upper edge.

[0015] As a preferred solution of the nest plate of the present invention, the needle-free pre-filled medicine core is inserted into the nest plate and corresponds one-to-one with the limiting components.

[0016] As a preferred embodiment of the nest plate of the present invention, the needle-free prefilled medicine core is tubular as a whole, divided into an upper end, a middle section and a lower end, and the diameters of the upper and lower ends are both larger than the middle section.

[0017] Beneficial effects of the present invention: improving the stability and safety of the medicine core: the limiting component is composed of a plurality of clips, and the overall configuration is bud-shaped. This design can better fix the medicine core, reduce shaking and deviation, and is especially safer during transportation or operation.

[0018] Adapt to drug cores of different specifications: The clips gradually converge from the fixed end to the free end to form a bud shape. This structural design can provide a certain multi-point clamping and elastic clamping effect, adapt to drug cores of different specifications or shapes, and is more compatible with the needle-free pre-filled drug core structure.

[0019] Protect the medicine core from damage: Symmetrical protrusions are set at each corner of the upper edge of the plate body, so that when the nest plate contacts the adjacent side, it is contacted by the protrusions, leaving a gap between the adjacent side, which is convenient for taking and placing the horizontal nest plate in the nest box. The plate body is groove-shaped as a whole, and the inner cavity formed by it protects the needle part at the upper end of the medicine core to prevent squeezing and the extrusion of the medicine liquid.

[0020] Improve space utilization and operational convenience: Several holes on the bottom surface are distributed in a rectangular shape, and the holes are staggered between two adjacent rows, so that the space of the rectangular bottom surface can be utilized to the maximum extent, and there is enough space between each adjacent limiting component to ensure that the needle-free pre-filled drug core is easy to take.

[0021] Enhance the stability of the nest board: the notches on the board body cooperate with the protrusions in the nest box to position and limit the nest board in the nest box, wherein two notches are arranged opposite to each other, and the two notches are diagonally symmetrically staggered to ensure the stability of the nest box.

[0022] In summary, the nest plate design of the present application provides a stable, safe, efficient and adaptable medicine core fixing solution through its unique limiting components and clip-folding structure, while also improving the operational convenience and space utilization of the nest plate, reducing the risk of contamination in the production process, and thus meeting the high standards of the pharmaceutical industry.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0038] Example 1

[0039] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a nesting plate, including a plate body part 100 and a plurality of limiting parts 200 distributed on the plate body part 100, the limiting parts 200 are composed of a plurality of clips 201, and the whole is arranged in a bud shape. The plate body part 100 includes a rectangular ring-shaped upper edge 101 and a rectangular bottom surface 102, and a circle of side walls 103 is arranged between the upper edge 101 and the bottom surface 102, forming a rectangular groove-shaped plate body part 100. A plurality of holes 104 are opened on the bottom surface 102, and the limiting parts 200 are arranged in the holes 104, and the clips 201 of the limiting parts 200 are arranged in the holes 104 at equal intervals. Each clip 201 of the same limiting part 200 is arranged inwardly inclined, and the plurality of clips 201 gradually gather from the fixed end to the free end to form a bud shape.

[0040] It should be noted that the nest plate is composed of a plate body part 100 and a plurality of limiting parts 200. The plate body part 100 is designed as a rectangular annular upper edge 101 and a rectangular bottom surface 102, which are connected by a side wall 103 to form a rectangular groove-shaped space. Its outer wall is also provided with a plurality of reinforcing ribs to increase the strength of the entire nest plate as required. The limiting part 200 is located in a hole 104 on the bottom surface 102 of the plate body part 100, and is composed of a plurality of clips 201. The overall shape is similar to a flower bud, so as to form an elastic, automatically retractable multi-claw clamp, which can clamp and fix the needle-free prefilled drug core 300 inserted therein at multiple points. At the same time, this design enables the limiting part 200 to adapt to needle-free prefilled drug cores 300 of different specifications.

[0041] Arrangement and shape of the clips 201: The clips 201 of the limiting component 200 are arranged at equal intervals in a circle in the hole 104, which helps to evenly distribute the clamping force on the medicine core. The clips 201 are provided with a plurality of clips 201 that can be set with different clamping strengths to adapt to different clamping effects. Each clip 201 is tilted inwardly and gradually converges from the fixed end to the free end to form a bud shape. This shape is conducive to the clip 201 being able to flexibly provide the necessary support and fixation for the medicine core when inserting or removing the medicine core.

[0042] Effect of the design: Stability: The bud-shaped limiting component 200 provides a stable platform to firmly fix the core and reduce shaking and deviation during transportation or operation. Adaptability: Since the clip 201 can be gradually retracted, this design allows the nest to adapt to cores of different diameters, improving the versatility of the nest. Protection: The design of the upper edge 101 and the inner cavity structure provide additional protection for the core, preventing the core from being squeezed or damaged during transportation.

[0043] Convenience of operation: The design of the protrusion 106 of the limiting component 200 and the staggered arrangement of the holes 104 make it easy to take the nest plate in the nest box, while reducing the friction and damage risk during operation. The rectangular distribution and staggered arrangement of the holes 104 maximize the utilization of the bottom surface 102 space, allowing more cores to be accommodated in a limited space. The regular design and the coordination of the protrusion 106 make the nest plate compatible with automated equipment, improving the efficiency of loading, unloading and transportation.

[0044] In summary, this nest plate design achieves stable fixation, protection and efficient operation of the needle-free prefilled drug core 300 through its unique structure of the limiting component 200 and the plate body component 100. This design not only improves the safety of the drug core during transportation and operation, but also enhances the adaptability and space utilization of the nest plate, and also provides convenience for automated operation, thereby meeting the high standards of the pharmaceutical industry.

[0045] The plate component 100 includes a rectangular ring-shaped upper edge 101 and a rectangular bottom surface 102. A circle of side walls 103 is arranged between the upper edge 101 and the bottom surface 102 to form a rectangular groove-shaped plate component 100. A plurality of holes 104 are distributed in a rectangular shape and are staggered between two adjacent rows.

[0046] In this embodiment, the plate member 100 is designed as a groove-shaped structure with an upper edge 101, and this design forms an inner cavity between the upper edge 101 and the bottom surface 102 of the plate member 100. The limiting member 200 is disposed in this inner cavity, and this layout provides additional protection for the needle-free prefilled drug core 300 inserted into the limiting member 200.

[0047] Since the needle part of the upper end 301 of the needle-free prefilled medicine core 300 is inserted into the limiting component 200, the needle part of the needle-free prefilled medicine core 300 is accommodated in the inner cavity, and the needle part of the upper end 301 is also protected to avoid contact with the outside world and potential extrusion. This protection mechanism effectively prevents the drug solution from being squeezed out, ensuring the integrity of the drug core and the stability of the drug.

[0048] Such an arrangement makes the upper and lower surfaces of the nest plate flat after the needle-free prefilled medicine core 300 is installed, and the overall appearance is relatively regular, which is conducive to neat stacking in the nest box. The regular design not only improves storage efficiency, but also facilitates automated loading and unloading and transportation, reducing the complexity and potential risk of damage in the logistics process.

[0049] The upper edge 101 is also designed for weighing needs. It matches with the protrusion 106 designed on the inner wall of the nest box, and the entire nest plate is suspended in the nest box. This suspended placement further reduces the chance of direct contact between the medicine core and the nest box, thereby reducing the risk of damage to the medicine core due to friction or collision. At the same time, the suspended design also facilitates cleaning and disinfection in the nest box, which helps maintain the hygiene standards of pharmaceutical products.

[0050] In summary, the nest plate design in this embodiment provides comprehensive protection for the needle-free prefilled drug core 300 through its unique grooved plate member 100 and inner cavity structure. This design not only ensures the safety and stability of the drug core, but also improves the storage and transportation efficiency of the nest plate. By reducing the contact between the drug core and the outside world, this design effectively prevents the extrusion of the drug solution and the damage of the drug core, and also facilitates the cleaning and maintenance of the nest box, thereby meeting the high standards of the pharmaceutical industry.

[0051] Furthermore, the design of the bottom surface 102 of the nesting board is carefully planned to optimize space utilization and operational convenience. The holes 104 on the bottom surface 102 are designed to be distributed in a rectangular shape, and this layout makes the arrangement of the holes 104 on the bottom surface 102 more orderly and uniform. The two adjacent rows of holes 104 are staggered, and this design can maximize the utilization of the bottom surface 102 space and avoid wasting any available space. At the same time, more limit components 200 can be accommodated in the limited bottom surface 102 area, thereby improving the capacity and storage efficiency of the nesting board.

[0052] Operational convenience: The staggered holes 104 also ensure that there is enough space between each adjacent limiting component 200, which provides convenience for the operator when taking the medicine core. Sufficient space reduces the interference between adjacent medicine cores and reduces the risk of misoperation or damage to the medicine core that may occur during the picking process. Visual effect and maintenance: The rectangular distribution and staggered holes 104 also bring visual neatness and regularity, which not only improves the appearance of the nest board, but also facilitates daily inspection and maintenance. Automation compatibility: This layout also takes into account the needs of automated operation, allowing automated equipment to more easily identify and access each limiting component 200, improving the accuracy and efficiency of automated operation.

[0053] Example 2

[0054] Reference Figure 4-Figure 6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the needle-free prefilled medicine core 300 is inserted into the nest plate and corresponds to the limiting component 200 one by one. The needle-free prefilled medicine core 300 is tubular as a whole, divided into an upper end 301, a middle section 302 and a lower end 303, and the diameters of the upper and lower ends are larger than the middle section 302.

[0055] The free end of the clip 201 is provided with an inward hook portion 202, which consists of a first surface 202a distributed at an obtuse angle to the inner side surface of the clip 201, a second surface 202b connected to the lower surface of the clip 201, and a third surface 202c is provided between the first surface 202a and the second surface 202b.

[0056] In this embodiment, the limiting component 200 of the nest plate is designed with a special geometric structure to achieve stable clamping of the needle-free prefilled medicine core 300 .

[0057] Clamping and fixing mechanism: The free end of each clip 201 of the limiting component 200 is retracted inward, forming a bud shape as a whole. This design makes it possible for the insertion of the medicine core 300 to push out each clip 201 when the needle-free prefilled medicine core 300 is inserted into the limiting component 200. As the clip 201 is pushed out, the free end of the clip 201 deviates outward. This causes the third surface 202c to change from an inclined state to a vertical state, which is caused by the obtuse angle formed between the inner side surface of the clip 201 and the first surface 202a and the inclined setting of the clip 201. This change increases the contact area between the third surface 202c and the needle-free prefilled medicine core 300, thereby providing a better clamping and fixing effect.

[0058] Prevent the core from falling off:

[0059] In addition, since the diameters of the upper end 301 and the lower end 303 of the needle-free prefilled drug core 300 are larger than the diameter of the middle section 302, when the limiting component 200 clamps the middle section 302 of the drug core, the two ends of the drug core cannot be reversely pulled out from the limiting component 200 due to their larger diameters. This design ensures that the drug core is firmly locked in the limiting component 200, prevents the drug core from falling off or shifting during transportation or operation, and thus improves the safety and stability of the drug core.

[0060] Furthermore, since the first surface 202a and the second surface 202b form an obtuse angle with the third surface 202c, the third surface 202c is structurally protruding, and this protruding design can be matched with the limiting groove provided in the middle section 302 of the part of the needle-free prefilled drug core 300. When the third surface 202c is inserted into the limiting groove, this specific type of needle-free prefilled drug core 300 can be effectively clamped and fixed, thereby increasing the adaptability and reliability of the fixing mechanism.

[0061] In summary, the nest plate design in this embodiment achieves stable clamping of the needle-free prefilled drug core 300 through its unique clip 201 structure and the coordination with the shape of the drug core. This design not only improves the safety of the drug core during transportation and operation, but also enhances the adaptability and versatility of the nest plate, making it applicable to drug cores of different specifications. By increasing the contact area between the clip 201 and the drug core and utilizing the shape characteristics of the drug core itself, this design ensures that the drug core is firmly locked in the limiting component 200, reducing potential risks in various operating environments.

[0062] The remaining structures are the same as those of Example 1.

[0063] Example 3

[0064] Reference Figure 1-Figure 3, which is the third embodiment of the present invention, is different from the second embodiment in that two inwardly recessed notches 105 are provided on the plate member 100, the two notches 105 are located on two opposite surfaces of the plate member 100, and the two notches 105 are staggered.

[0065] In this embodiment, the matching design between the plate body part 100 of the nesting plate and the nesting box takes into account accurate positioning and stability. The notch 105 matches the protrusion: the plate body part 100 is designed with specific notches 105, which match the protrusions in the nesting box. This design is used to accurately position and limit the nesting plate in the nesting box. The layout of the notch 105: the two notches 105 are arranged opposite to each other and are distributed in a diagonally symmetrical staggered manner. This layout not only provides multiple positioning points, but also increases the stability of the nesting plate in the nesting box. At the same time, the nesting plate has no front and back distinction, and it only needs to match the notch 105 with the protrusion.

[0066] Stability effect: The design of the diagonally symmetrically staggered notches 105 allows the nest board to be evenly supported in the nest box, reducing the instability caused by the center of gravity offset. This layout also helps to disperse the external forces on the nest board, such as vibration and impact during transportation or handling, thereby protecting the nest board and the core from damage. Convenience of loading and unloading: The matching design of the notches 105 and the protrusions simplifies the loading and unloading process of the nest board. The operator can easily insert or remove the nest board from the nest box, improving work efficiency.

[0067] In summary, the nest plate design in this embodiment realizes accurate positioning and stable limiting of the nest plate in the nest box by setting the notch 105 on the plate body part 100 and cooperating with the protruding part in the nest box. This design not only improves the stability of the nest plate, but also simplifies the loading and unloading process, increases the compatibility and versatility of the system, and also facilitates the cleaning and maintenance of the nest box, thereby meeting the high efficiency, safety and sanitation requirements of pharmaceutical logistics.

[0068] Symmetrical protrusions 106 are provided at each corner of the upper edge 101 , and the protrusions 106 are located on the side of the upper edge 101 .

[0069] This description refers to a specific feature of the nesting board design, namely the symmetrical protrusions 106 provided at the corners of the upper edge 101. When the nesting board contacts the adjacent side (which may be another nesting board or the inner wall of the nest box), the contact point is these protrusions 106, rather than the flat part of the nesting board. Due to the presence of the protrusions 106, a certain gap will be left between the nesting board and the adjacent side. The existence of this gap has two main benefits: first, it reduces the direct contact area between the nesting boards, thereby reducing friction, making it easier to move the nesting boards horizontally and to take them in and out of the nest box. Second, the gap can also act as an air channel to help ventilate and dissipate heat from the nesting board, especially when multiple nesting boards are stacked in the nest box.

[0070] Convenience of operation: The design of protrusion 106 makes the operation of taking and placing the nest board in the nest box smoother, because the protrusion 106 provides a clear contact point, and the operator can grasp the nest board more easily without worrying about interference between the nest boards. Stability and protection: The protrusion 106 also helps to protect the edges of the nest board and avoid damage to the nest board during the process of taking and placing. It also increases the stability of the nest board because the protrusion 106 can serve as a support point to disperse the pressure on the nest board.

[0071] In summary, the design of providing symmetrical protrusions 106 at the corners of the upper edge 101 of the nesting board is intended to improve the convenience of taking and placing the nesting board in the nest box, while reducing friction and protecting the edges of the nesting board. This design takes into account the practicality of operation and the protection of the nesting board, making the nesting board more efficient and durable in practical applications.

[0072] The remaining structure is the same as that of Example 2.
