Description

Technical Field

[0001] This application relates to the field of medical device packaging boxes, and in particular to a packaging box for fixing implants. Background Technology

[0002] In recent years, my country's medical industry has developed rapidly, and occluders used for left atrial appendage occlusion have gradually become well-known. However, during the storage and transportation of occluders, inappropriate fixing methods have led to issues such as shaking, friction damage, accidental drops, and disruption of the sterile barrier system, resulting in significant waste and losses. Moreover, due to individual differences, there are many specifications for the same type of medical device, leading to a variety of packaging specifications and poor versatility. This can easily increase raw material costs and cause problems such as mixing materials, incorrect selection, or misuse of packaging boxes.

[0003] In the prior art, packaging boxes generally include blister boxes. After the medical stent is placed inside, the opening of the blister box is sealed with dialysis paper. The blister box has a cavity for placing the stent. In order to fix the stent, symmetrical buckles are usually set on the side wall of the cavity of the stent. These buckles make it difficult to demold during the production process of the blister box. Forcible demolding can also easily cause damage to the blister box, resulting in an increased scrap rate.

[0004] In addition, the plugging device often includes an umbrella-shaped component and a disc-shaped component, which can be installed separately or as a whole. When the two are installed as a whole, because they are close together or close to each other in their natural state, the umbrella-shaped component and the disc-shaped component will rub against each other when subjected to external force, which can easily damage the outer surface of each other. In addition, long-term transportation often leads to the product being scrapped directly.

[0005] In summary, the existing technology has the following problems that urgently need to be solved: First, the packaging box is difficult to fix the implant in three dimensions at the same time: top, bottom, left, right, and front and back; second, the packaging box cannot be adapted to multiple sizes of occluder products; third, when the umbrella-shaped and disc-shaped components are stored together, the packaging box cannot prevent friction damage between the two components. Summary of the Invention

[0006] This application is made in view of the above and other ideas.

[0007] One of the purposes of this application is to overcome the shortcomings of the prior art and provide a packaging box for fixing implants.

[0008] The objective of this invention is achieved through the following solution: A packaging box for fixing an implant, the implant including a waist structure, the packaging box including a first box body, the first box body including a first receiving box, a locking structure and a limiting unit, the locking structure including a first slide groove and a second slide groove, the waist structure moving along the first slide groove to the center of the first box body, the limiting unit moving along the second slide groove to connect with the locking structure, and the limiting unit and the first slide groove forming a closed space, the closed space restricting the horizontal or forward and backward movement of the waist structure; and, a portion of the limiting unit and the locking structure together form an axial locking portion.

[0009] The objective of this invention can also be further achieved through the following technical solutions: Furthermore, the limiting unit includes a connecting member and a limiting member, the limiting member being disposed on both sides of the connecting member; and the connecting member and the locking structure together form the axial locking portion, the connecting member and the first sliding groove forming the closed space.

[0010] Furthermore, the implant includes an occluder, which includes an adaptive disc-shaped member, an umbrella-shaped member, and a waist structure. The umbrella-shaped member includes a plurality of coiled wires. The locking structure includes an anti-rotation unit for preventing the occluder from rotating, with at least two adjacent coiled wires located on both sides of the anti-rotation unit. The disc-shaped member and the umbrella-shaped member are disposed on both sides of the locking structure.

[0011] Furthermore, the anti-rotation unit is disposed on the lower end face of the locking structure.

[0012] Furthermore, the anti-rotation unit prevents the umbrella-shaped member from rotating.

[0013] Furthermore, the center plane of the first chute coincides with the center plane of the anti-rotation unit.

[0014] Furthermore, the axial height of the axial locking portion is greater than the distance between the disc-shaped member and the umbrella-shaped member.

[0015] Furthermore, when the occluder is placed, the connector and the disc are connected or in contact.

[0016] Furthermore, the packaging box also includes an outer box, a second box, and a third box, wherein the first box, the second box, and the third box can be respectively installed inside the outer box; and the second box is used to install the umbrella-shaped component, and the third box is used to install the disc-shaped component.

[0017] Furthermore, the length, width, and height of the first box, the second box, and the third box are equal.

[0018] Furthermore, the locking structure includes two second sliding grooves, which are disposed on both sides of the first sliding groove; and the connecting member and the limiting member are not at the same height, with a step between them.

[0019] Furthermore, the first receiving box includes two mating platforms, each mating platform having an arcuate surface, and an open receiving cavity is formed between the two mating platforms; and an arcuate protrusion is provided at the center of the open receiving cavity.

[0020] Furthermore, the center of the umbrella-shaped component is recessed, and the center of the umbrella-shaped component is connected to the arc-shaped protrusion.

[0021] Furthermore, the locking structure includes a lower insert, the surface of which is provided with a locking protrusion, and the inner side surface of the first receiving box is provided with a recess. The locking protrusion and the recess are connected to fix the first receiving box and the locking structure. In addition, the locking structure includes a horizontal plane, and the connecting member and the limiting member are located above and below the horizontal plane, respectively.

[0022] Furthermore, the disc-shaped member and the umbrella-shaped member are located above and below the horizontal plane, respectively.

[0023] Furthermore, the lower insert is disposed below the horizontal plane.

[0024] Furthermore, the lower insert includes a first mating block and a second mating block, the area of ​​the second mating block being half that of the first mating block. The purpose of this design is that the lower insert does not completely fill the first receiving box, thus creating a retrieval space between the locking structure and the first receiving box.

[0025] Furthermore, the outer peripheral surface of the lower insert is at least partially in contact with the inner surface of the first receiving box, and the inner peripheral surface of the lower insert is at least partially in contact with the outer surface of the mating platform; and the overall height of the locking structure is less than the height of the first box body.

[0026] Furthermore, the second box body includes a second receiving box and a second cover plate. The second receiving box includes a first base surface, a second base surface, a first anti-rotation platform, and a second anti-rotation platform. The first anti-rotation platform and the second anti-rotation platform are provided with a small hole at their center. The umbrella-shaped member includes a cylindrical member located at its center, and the cylindrical member is placed in the small hole. The second receiving box can hold two umbrella-shaped members of different sizes.

[0027] Furthermore, the distance between the first base surface and the second cover plate is greater than or equal to the height of the umbrella-shaped member in its natural state.

[0028] Furthermore, the distance between the second base surface and the second cover plate is greater than or equal to the height of the umbrella-shaped member in its natural state.

[0029] Furthermore, the third box body includes a third receiving box and a third cover plate; and the third receiving box includes a storage slot, which is rectangular, circular or strip-shaped.

[0030] Furthermore, the storage slot is topped by a third cover plate that is connected to the third receiving box.

[0031] Furthermore, the storage slot is embedded with an accessory holder, the hardness of which is lower than that of the storage slot. The accessory holder has an embedded structure, and the accessory connecting the disc-shaped component and the umbrella-shaped component is placed in the embedded structure.

[0032] Furthermore, the accessory holder is made of silicone.

[0033] Furthermore, the accessories are arranged in a regular pattern within the embedded structure.

[0034] Furthermore, the accessory holder and the embedded structure are used to quickly assist in the installation and removal of the accessory.

[0035] Furthermore, the locking structure also includes anti-misalignment bosses, which are disposed on both sides of the first slide groove; and the anti-rotation unit is in the shape of an isosceles triangle.

[0036] Furthermore, the outer box, the first box, the second box, and the third box are all covered with dialysis paper.

[0037] Furthermore, the first housing is used to load the inferior vena cava filter.

[0038] Compared with the prior art, the advantages of the technical solution of this application include at least the following: 1. In existing technologies, due to the delicate structure of medical products, their stability cannot be guaranteed during transportation, which can easily cause damage. Furthermore, some products, such as occluders like the commercially available SimuLock, are also susceptible to damage. ®The left atrial appendage occluder includes an optional, separate type. Existing technologies often package the two separately, increasing the number of packaging boxes and adding to the operator's choices and operational steps. This application solves these problems. First, it designs a locking structure that connects to the waist structure of the occluder. The locking structure includes a first groove and a second groove. The first groove provides a clear and easily identifiable path for the waist structure to enter the center of the locking structure. The second groove provides a packaging assembly path for the restraining unit to be fixed to the locking structure. The restraining unit and the first groove form a closed space, allowing the waist structure to be controlled in the anterior-posterior direction. The first groove has a width slightly greater than or equal to the diameter of the waist structure, thus restricting the left and right movement of the waist structure. Furthermore, because the gap between the umbrella-shaped and disc-shaped components of the plug is small, and the thickness of the limiting unit and the locking structure is greater than the gap between them, the front-back, left-right, and up-down directions of the plug are all restricted, thereby ensuring the safety of the plug during transportation. On the other hand, the first housing of this application accommodates the entire plug, and the locking structure and limiting unit separate the umbrella-shaped and disc-shaped components into two spaces, preventing them from touching during transportation and avoiding frictional damage when the umbrella-shaped and disc-shaped components are stored as a single unit.

[0039] 2. Unlike existing technologies, the card slot structure of this application also includes an anti-rotation unit, which is in the shape of an isosceles triangle or a cake slice. The purpose of this design is that: for umbrella-shaped parts of different specifications, the number of coiled filaments is usually fixed, the included angle between the coiled filaments is fixed, umbrella-shaped parts of different specifications are similar, and the acute angle of the anti-rotation unit is the same as the included angle between the coiled filaments. Therefore, the anti-rotation unit can adapt to umbrella-shaped parts of similar but different specifications, and the first box can be used to install occluder products of different specifications.

[0040] 3. Unlike existing technologies, the packaging box also includes an outer box, a second box, and a third box. The second box is used to install the umbrella-shaped component, and the third box is used to install the disc-shaped component. The first, second, and third boxes can all be installed inside the outer box. The advantages of this design are: firstly, the double-layered box ensures that the first, second, and third boxes inside are not contaminated by biological sources, thus ensuring the sterility of the sealing device; secondly, the first, second, and third boxes are compatible with the same outer box, reducing the number of packaging boxes and significantly lowering packaging design costs.

[0041] 4. Unlike existing technologies, the positioning structure includes a horizontal plane, with the connecting part and the limiting part located above and below the horizontal plane, respectively. The disc-shaped part and the umbrella-shaped part are located above and below the horizontal plane, respectively. Thus, the umbrella-shaped part is placed in an open receiving cavity. For occluders with larger size but relatively controllable drop, the umbrella-shaped part will be axially compressed. The open receiving cavity provides space for the coiled wire to move. The coiled wire will move radially and be in a comfortable posture, and will not be deformed by compression.

[0042] 5. Unlike existing technologies, the positioning structure has three functions: First, the positioning structure is equipped with a lower insert and a positioning protrusion to achieve a fixed connection with the first receiving box; second, the detachable connection between the positioning structure and the limiting unit provides protection and convenience for loading and unloading implants; third, the positioning structure and the limiting unit form a closed space after connection, which restricts the movement of the implant in three dimensions, demonstrating an ingenious design concept.
