Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a packaging system. Background Technology

[0002] A thrombus is a blood clot that forms within a blood vessel, potentially blocking it and causing local tissue ischemia and necrosis or organ damage. In severe cases, it can lead to fatal diseases such as pulmonary embolism, myocardial infarction, and stroke, even threatening life. Therefore, filtering, capturing, and removing thrombi is crucial. Thrombofiltration filters are commonly used to prevent venous thromboembolism and can capture emboli caused by varicose veins and deep vein thrombosis. Thrombofiltration filters are typically compressed and placed inside a delivery catheter, which is then inserted into the body. However, during release within the body, the filter may adhere to itself or become snagged, preventing complete deployment and causing operational failure. Furthermore, depending on the location of the thrombus, the same type of thrombofiltration filter may have delivery catheters of varying lengths. Medical blister packs are commonly used for packaging thrombofiltration medical devices. Utility Model Content

[0003] This utility model provides a packaging system, including a packaging box and a medical device placed inside the packaging box. The medical device includes an expansion structure and a connecting structure. The expansion structure is connected to the connecting structure and has an expanded state. The packaging box includes a first groove structure and a second groove structure. The first groove structure is used to place the expansion structure in the expanded state, and the second groove structure is used to place the connecting structure. The radial dimension of the first groove structure is larger than the radial dimension of the second groove structure. There are multiple first groove structures, and each first groove structure contains one expansion structure in the expanded state. When the medical device includes one expansion structure, multiple first groove structures are used to place expansion structures in the expanded state that are connected to connecting structures of different lengths respectively; or, when the medical device includes multiple expansion structures, the multiple expansion structures are sequentially connected to one connecting structure, and multiple first groove structures are used to place multiple expansion structures in the expanded state respectively.

[0004] In the aforementioned packaging system, by setting a first groove structure and a second groove structure, the first groove structure is used to hold the expanded structure in an inflated state, and the second groove structure is used to hold the connecting structure. The radial dimension of the first groove structure is larger than that of the second groove structure, ensuring that the expanded structure of the medical device remains in an inflated state before the operator's operation. This prevents the expanded structure from being compressed for a long time, which could cause it to stick or snag when released inside the body, leading to operational failure. Furthermore, by setting multiple first groove structures, each containing one expanded structure, multiple first groove structures can be used to hold expanded structures connected to connecting structures of different lengths when the medical device includes one expanded structure; or, when the medical device includes multiple expanded structures, with multiple expanded structures sequentially connected to a connecting structure, multiple first groove structures can be used to hold multiple expanded structures in an inflated state. This improves the adaptability of the packaging box, allowing one packaging box to accommodate multiple models or types of medical devices, and reduces production costs. Attached Figure Description

[0012] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0013] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0014] It should be noted that the terms "distal" and "proximal" are used as directional terms, which are commonly used in the field of interventional medical devices. "Distal" refers to the end that is farthest from the operator during the procedure, while "proximal" refers to the end that is closest to the operator during the procedure.

[0015] See Figures 1 to 4 This embodiment provides a packaging system 100, which includes a packaging box 1 and a medical device 2 placed inside the packaging box 1. The packaging box 1 is used for packaging, storing, and transporting the medical device 2.

[0016] The medical device 2 includes an expansion structure 21 and a connecting structure 22. The expansion structure 21 is connected to the connecting structure 22 and is in an expanded state. In this embodiment, the expansion structure 21 can be an expandable medical device such as a thrombus filter, balloon, vascular stent, heart valve, or occlusion device, and the connecting structure can be a slender structure such as a sheath, connecting wire, delivery cable, or connecting tube. To further protect the connecting structure 22, a protective sleeve 220 can be fitted over the connecting structure 22 (see [reference]). Figure 7 Then, the connecting structure 22, which is covered with a protective cover, is placed into the packaging box 1.

[0017] The packaging box 1 includes a first groove structure 11 and a second groove structure 12. The first groove structure 11 is used to accommodate the expanded structure 21 in an expanded state, and the second groove structure 12 is used to accommodate the connecting structure 22. The radial dimension of the first groove structure 11 is larger than the radial dimension of the second groove structure 12. Here, the radial dimension refers to the dimension in a direction perpendicular to the length direction of either the first groove structure 11 or the second groove structure 12. Figure 4 In the first groove structure 11, the radial dimension is D1, and the radial dimension of the second groove structure 12 is D2.

[0018] There are multiple first groove structures 11, each containing one expanded structure 21 in an expanded state. When the medical device 2 includes one expanded structure 21, the multiple first groove structures 11 are used to respectively place the expanded structures 21 connected to connecting structures 22 of different lengths in an expanded state. It is understood that the medical device 2 can include multiple specifications, and the lengths of the connecting structures 22 for different specifications of medical devices 2 are different. Therefore, when different specifications of medical devices 2 are placed in the same packaging box 1, the positions of the connection points between the expanded structure 21 and the connecting structure 22 in the packaging box 1 are different. Therefore, multiple first groove structures 11 are provided to accommodate medical devices of different specifications. Alternatively, when the medical device 2 includes multiple expanded structures 21, the multiple expanded structures 21 are sequentially connected to one connecting structure 22, and the multiple first groove structures 11 are used to respectively place multiple expanded structures 21 in an expanded state.

[0019] In the aforementioned packaging system 100, by providing a first groove structure 11 and a second groove structure 12 in the packaging box 1, the first groove structure 11 is used to place the expanded structure 21 in an expanded state, and the second groove structure 12 is used to place the connecting structure 22. The radial dimension of the first groove structure 11 is larger than the radial dimension of the second groove structure 12, so that the expanded structure of the medical device 2 is always in an expanded state before the operator operates, avoiding the long-term compression of the expanded structure 21 of the medical device 2, which would cause the expanded structure 21 of the medical device 2 to stick or snag when released in the body, thus resulting in operation failure. In addition, by setting multiple first groove structures 11, each first groove structure 11 accommodating an expanded structure 21 in an expanded state, when the medical device 2 includes an expanded structure 21, the multiple first groove structures 11 are used to respectively place the expanded structures 21 in an expanded state connected to the connecting structures 22 of different lengths; or, when the medical device 2 includes multiple expanded structures 21, the multiple expanded structures 21 are sequentially connected to a connecting structure 22, and the multiple first groove structures 11 are used to respectively place the multiple expanded structures 21 in an expanded state, thereby improving the adaptability of the packaging box 1, making it convenient for one packaging box 1 to adapt to multiple models or types of medical devices 2, and reducing production costs.

[0020] See Figure 5 The packaging box 1 includes a support structure 110 and a main structure 120 that are connected to each other. The support structure 110 is located at the bottom of the packaging box 1 and is used to contact the placement plane. The support structure 110 supports the main structure 120 and keeps the main structure 120 away from the placement plane. The support structure 110 keeps the packaging box 1 balanced and stable on the placement plane.

[0021] Combination Figure 4 and Figure 5The packaging box 1 includes a third groove structure 13, which protrudes towards the bottom of the packaging box 1 to form a support structure 110. The depth of the third groove structure 13 is greater than the depth of the first groove structure 11 or the depth of the second groove structure 12, so that the support structure 110 formed by the third groove structure 13 can protrude from the bottom of the packaging box 1, preventing the expansion structure 21 placed in the first groove structure 11 and the connecting structure 22 placed in the second groove structure 12 from contacting the placement plane, thereby providing a buffer force when subjected to force during transportation and reducing the deformation of the expansion structure 21 and the connecting structure 22 of the medical device caused by external force.

[0022] In other embodiments, the support structure 110 may also be a protruding structure that is detachably or non-detachably connected to the bottom surface of the main structure 120; or, the support structure 110 may be a protruding structure formed by a non-groove structure, and the protruding structure may be integrally formed with the main structure 120, for example, the protruding structure may be a non-hollow structure. The number of support structures 110 may be one or more.

[0023] See Figure 6 When one packaging box 1 is stacked vertically with another packaging box 1, the third groove structure 13 of the upper packaging box 1 is inserted into the third groove structure 13 of the lower packaging box 1. The edges of the main body structures 120 of the two packaging boxes 1 are spaced apart, which facilitates the operator to correctly handle the packaging boxes during assembly and avoids damage to the packaging boxes. At the same time, it avoids the two packaging boxes being too tightly attached, making them difficult to handle and resulting in waste of packaging boxes.

[0024] See Figure 4 and Figure 5In one embodiment, a third groove structure 13 at least partially overlaps with a first groove structure 11. During transportation, when the first groove structure 11 is subjected to force, because it at least partially overlaps with the third groove structure 13, the first groove structure 11 can immediately distribute the force to the third groove structure 13, greatly reducing deformation and thus preventing deformation of the expansion structure 21 within the first groove structure 11. In this embodiment, the third groove structure 13 and the first groove structure 11 are arranged in a cross configuration to achieve at least partial overlap. In other embodiments, the third groove structure 13 and the first groove structure 11 can also partially overlap by having their sides close together and connected; or the first groove structure 11 can be disposed within the third groove structure 13 and located near the top of the third groove structure 13, with a protruding structure on the inner wall of the third groove structure 13 to facilitate the positioning and fixing of the expansion structure 21 in an expanded state. Furthermore, since the first groove structure 11 and the third groove structure 13 at least partially overlap, the operating space at the first groove structure 11 is expanded, making it easier for the operator to take out the expansion structure 21 inside the first groove structure 11 from the packaging box 1.

[0025] In one embodiment, the packaging box 1 has a roughly rectangular structure, including four arc-shaped corners for easy placement in the packaging system. Multiple third groove structures 13 are provided, with two of them located at opposite corners of the roughly rectangular structure to offer better support and balance. In this embodiment, four third groove structures 13 are provided, one at each of the four corners of the roughly rectangular structure, resulting in a more stable placement of the packaging box 1 and facilitating assembly, transportation, and handling.

[0026] Furthermore, from the top to the bottom of packaging box 1 (see...) Figure 5 The direction of the middle arrow A, that is Figure 4 From this perspective, the third groove structure 13 has a length direction (see [reference]). Figure 4 (The directions of the middle arrows B1, B2, B3, and B4) indicate that the length direction of the third groove structure 13 is towards the corner where the third groove structure 13 is located, so that the two third groove structures 13 located at the two diagonally set corners of the rectangular structure can improve the overall balance of the packaging box 1 while having a better effect of dispersing the force.

[0027] In one embodiment, see Figure 2 and Figure 7The medical device 2 also includes a handle structure 23, and the packaging box 1 includes a fourth recessed structure 14. The handle structure 23 is placed within the fourth recessed structure 14, which at least partially overlaps with the third recessed structure 13. The depth of the fourth recessed structure 14 is less than or equal to the depth of the third recessed structure 13, thereby reducing the force on the handle structure 23 within the third recessed structure 13 and preventing damage to the handle structure 23. When the depth of the fourth recessed structure 14 is equal to the depth of the third recessed structure 13, the support performance of the third recessed structure 13 located therein is further improved. Furthermore, since the fourth recessed structure 14 at least partially overlaps with the third recessed structure 13, the space within the fourth recessed structure 14 is expanded, making it easier for the operator to remove the handle structure 23 from the packaging box 1.

[0028] In one embodiment, the second groove structure 12 includes a multi-layer structure arranged sequentially from the outer periphery of the packaging box towards the center. Adjacent layer structures 121 / 122 / 123 include a cross structure 120, thereby allowing the packaging box 1 to accommodate a longer distance of the second groove structure 12 and making the placement of the connecting structure 22 within the second groove structure 12 more flexible.

[0029] In one embodiment, the packaging box 1 includes a planar structure 10. When viewed from the top to the bottom of the packaging box 1, the area of ​​the planar structure 10 occupies at least one-quarter of the plane area on which the packaging box 1 is located, so that the planar structure 10 serves as a storage platform, making it convenient to place instruction manuals or other items needed for operation on the planar structure 10, thereby improving operability.

[0030] See Figure 7 The medical device 1 also includes a syringe 24, an infeeding sheath 25, and a guidewire assembly 26, which are also placed in the grooves inside the packaging box 1.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
