Description

Technical Field

[0001] This application relates to the field of medical device packaging technology, and in particular to a blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain. Background Technology

[0002] With the development of minimally invasive neurosurgical techniques, various sophisticated medical devices are widely used in actual surgeries, which places higher demands on the packaging of medical devices. Currently, most medical devices on the market are packaged in simple plastic bags or relatively simple cardboard boxes. These traditional packaging methods cannot effectively protect the internal equipment from external physical factors, especially during long-distance transportation, which may lead to damage or contamination of the devices, seriously affecting the safety and success rate of the surgery.

[0003] To improve the safety of medical devices during transportation, the industry typically employs two methods: first, increasing the use of cushioning materials such as foam pads and bubble wrap, filling the outer packaging with a large amount of cushioning material to achieve shock absorption and impact prevention; second, designing specialized rigid containers, which not only have good sealing performance but also effectively resist changes in external pressure and prevent moisture intrusion and corrosion. However, both methods have significant limitations: the former increases packaging volume, leading to higher warehousing costs; while the latter offers better protection, its higher production cost hinders large-scale application.

[0004] While current medical device packaging solutions on the market can meet basic needs to some extent, they still fail to fundamentally solve the problem of how to achieve comprehensive protection of high-end medical devices in an economical and efficient manner. This is especially true for precision instruments that are extremely sensitive to changes in the external environment, as traditional packaging methods often cannot guarantee their integrity after long-distance transportation.

[0005] Therefore, this application proposes a blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain. Utility Model Content

[0006] This application proposes a blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain, addressing the problems mentioned in the background art. It utilizes high-strength PETG material as the main component, incorporating customized grooves, silicone pads, and elastic support feet to effectively protect the catheter. Users can easily complete the packaging process by following the prescribed steps. Whether for daily storage or long-distance transportation, it ensures the safety of the device, significantly improving the safety of the three-dimensional fixation and guidance dilation catheter during transportation, reducing the damage rate caused by external factors, extending the device's lifespan, optimizing the packaging process, simplifying operation steps, and reducing the workload of medical staff. It also saves hospitals additional expenses caused by frequent replacement of damaged devices. The unique material combination and structural design give the packaging box sufficient strength to withstand external impacts while maintaining a low cost advantage, making it easy to apply to more types of precision medical devices and greatly improving the device's practicality.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain includes a blister packaging box body and an aluminum foil film. The blister packaging box body consists of an upper cover and a lower base, which are tightly closed by a snap-fit ​​connection. The lower base has grooves inside that conform to different components of the catheter; these grooves are customized. Each of the four corners of the lower base has an elastic support foot. A protective component is provided in the groove of the lower base, including a silicone pad, and the edges of the groove are equipped with soft silicone pads.

[0009] In a preferred embodiment, the silicone pad is disposed at the edge of the groove;

[0010] The device's usability is enhanced by the soft silicone padding along the groove edge, which gently wraps around the surface of the catheter during insertion, preventing scratches.

[0011] In a preferred embodiment, the silicone pad is made of medical-grade soft silicone;

[0012] By selecting medical-grade soft silicone for the silicone pad, safety in contact with the human body is ensured, thereby improving the device's practicality.

[0013] In a preferred embodiment, a snap-fit ​​mechanism is provided between the upper cover and the lower seat. The snap-fit ​​mechanism includes a sleeve, a screw, an upper connector, a connecting rod, a lower connector, a snap-fit ​​block, a spring, a movable rod, and a stop block.

[0014] By incorporating a snap-fit ​​mechanism, the blister packaging box can be quickly opened or closed. It is simple to operate, convenient to use, and has a certain degree of security, preventing it from being opened arbitrarily during use and storage, thus enhancing the practicality of the device.

[0015] In a preferred embodiment, the two sleeves are respectively fixedly connected to both sides of the upper cover, and the two sides of the lower seat are respectively fixedly connected to the locking blocks;

[0016] By setting up a sleeve and a locking block, the sleeve is used to install the upper buckle assembly, and the locking block is used to install the lower buckle assembly. The connection between the upper cover and the lower base is achieved through the upper buckle assembly and the lower buckle assembly, thereby improving the practicality of the device.

[0017] In a preferred embodiment, two springs are symmetrically arranged inside the two blocks respectively. The end of each spring away from the other spring is fixedly connected to the inside of the block. A movable rod is provided on the inner side of each spring, and a stop block is fixedly connected to the end of each movable rod that is close to it.

[0018] By setting up the upper buckle component, when it is necessary to close the upper cover and the lower seat, simply insert the connecting rod into the locking block so that the lower connector passes through the two blocks and locks in place, thereby improving the practicality of the device.

[0019] In a preferred embodiment, both sleeves are threaded with screws inside, and the bottom ends of both screws are fixedly connected to upper connectors. Both screws are provided with connecting rods inside, and the bottom ends of both connecting rods extend into the interior of the locking block and are fixedly connected to lower connectors. The exterior of both connecting rods contacts the exterior of the stop block.

[0020] By setting up a lower locking assembly, when the top cover needs to be opened, rotating the screw causes it to move downwards within the sleeve. As the screw moves downwards, it pulls the connected upper connector into the locking block. When the upper connector passes two stops, the pressure causes the two stops to move away from the upper connector via the movable rod. When the upper connector contacts the lower connector, pulling the connecting rod and simultaneously rotating the screw causes the lower connector, along with the upper connector, to move upwards through the two stops, disengaging from the locking block, thus opening the top cover and improving the device's practicality.

[0021] In a preferred embodiment, the outer surface of the blister packaging box body is provided with an aluminum foil film;

[0022] By adding a layer of specially made aluminum foil film to the original blister packaging box, this film has excellent barrier properties, which can further enhance the sealing and stability of the entire packaging system. This not only improves the product's shelf life but also makes it more suitable for harsh outdoor transportation conditions, thereby enhancing the practicality of the device.

[0023] The beneficial effects of this application are:

[0024] 1. This blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain uses high-strength PETG material as the main material and combines customized grooves, silicone pads, and elastic support feet to effectively protect the catheter. Users can easily complete the packaging operation by simply following the prescribed steps. Whether for daily storage or long-distance transportation, it ensures the safety of the device, significantly improves the safety of the three-dimensional fixation and guidance dilation catheter during transportation, reduces the damage rate caused by external factors, extends the service life of the device, optimizes the packaging process, simplifies the operation steps, reduces the workload of medical staff, and also saves hospitals the extra expenses caused by frequent replacement of damaged devices. The unique material combination and structural design make the packaging box not only strong enough to resist external impacts, but also maintain a low cost advantage, making it easy to promote and apply to more types of precision medical devices, greatly improving the practicality of the device.

[0025] 2. This blister packaging box for a three-dimensional fixation and guidance dilation catheter for the brain can effectively absorb external energy and protect the contents from damage during transportation and handling, even in the event of minor collisions, thanks to its own hardness and the cushioning effect of its elastic support feet. The groove edges are equipped with soft silicone pads that gently wrap the surface of the catheter when it is inserted, preventing scratches. If the silicone pads are found to be severely worn, they should be replaced promptly to maintain the optimal protective function of the packaging box. Elastic support feet are also provided at the four corners of the base to cushion impacts. Considering that a higher level of moisture and water resistance may be required in some cases, a special aluminum foil film is added to the original blister packaging box. This film has excellent barrier properties, further enhancing the sealing and stability of the entire packaging system. This not only improves the product's shelf life but also makes it more suitable for harsh outdoor transportation conditions, greatly enhancing the practicality of the device.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Reference Figure 1-4 A blister packaging box for a three-dimensional fixation and guidance expansion catheter for the brain includes a blister packaging box body (1) and an aluminum foil film (3). The blister packaging box body 1 is composed of an upper cover 11 and a lower seat 12, which are tightly closed by a snap-fit ​​connection. The lower seat 12 has grooves 121 inside that fit different components of the catheter. Customized grooves 121 are used. Elastic support feet 2 are provided at the four corners of the lower seat 12. A protective component 1211 is provided in the groove 121 of the lower seat 12. The protective component 1211 includes a silicone pad 12114. The edge of the groove 121 is equipped with a soft silicone pad 12114.

[0033] Reference Figure 2-4 The silicone pad 12114 is provided at the edge of the groove 121; by providing a soft silicone pad at the edge of the groove, the surface of the catheter can be gently wrapped when it is inserted, avoiding scratches and thus improving the usability of the device.

[0034] Reference Figure 2-4 The silicone pad 12114 is made of medical-grade soft silicone. By selecting medical-grade soft silicone for the silicone pad, safety in contact with the human body is ensured, thereby improving the practicality of the device.

[0035] Reference Figure 1-3 A locking mechanism 4 is provided between the upper cover 11 and the lower seat 12. The locking mechanism 4 includes a sleeve 41, a screw 411, an upper connector 4111, a connecting rod 412, a lower connector 4121, a locking block 42, a spring 421, a movable rod 422, and a stop block 4221. By setting the locking mechanism 4, the blister packaging box body 1 can be opened or closed quickly. It is simple to operate, convenient to use, and has a certain degree of safety, preventing it from being opened at will during use and storage, thereby improving the practicality of the device.

[0036] Reference Figure 1-3Two sleeves 41 are fixedly connected to both sides of the upper cover 11, and two locking blocks 42 are fixedly connected to both sides of the lower seat 12. By setting the sleeves 41 and locking blocks 42, the sleeves 41 are used to install the upper buckle assembly, and the locking blocks 42 are used to install the lower buckle assembly. The connection between the upper cover 11 and the lower seat 12 is realized through the upper buckle assembly and the lower buckle assembly, thereby improving the practicality of the device.

[0037] Reference Figure 1-3 Two springs 421 are symmetrically arranged inside the two locking blocks 42. The end of each spring 421 away from the other is fixedly connected to the inside of the locking block 42. A movable rod 422 is provided on the inner side of each spring 421. A stop block 4221 is fixedly connected to the end of each movable rod 422 that is close to it. By setting the upper buckle assembly, when it is necessary to close the upper cover 11 and the lower seat 12, simply insert the connecting rod 412 into the locking block 42, so that the lower connector 4121 passes through the two stop blocks 4221 for locking, thereby improving the practicality of the device.

[0038] Reference Figure 1-3 Both sleeves 41 are threaded with screws 411 inside, and the bottom ends of both screws 411 are fixedly connected to upper connectors 4111. Both screws 411 have connecting rods 412 inside, and the bottom ends of both connecting rods 412 extend into the interior of the locking block 42 and are fixedly connected to lower connectors 4121. The exterior of both connecting rods 412 contacts the exterior of the stop block 4221. By setting the lower locking assembly, when the upper cover 11 needs to be opened, rotating the screws 411 causes them to move downwards within the sleeves 41. When the screws 411 move downwards... This will cause the upper connector 4111 connected to it to extend into the locking block 42. When the upper connector 4111 passes through the two stops 4221, the pressure will cause the two stops 4221 to move away from the upper connector 4111 through the movable rod 422. When the upper connector 4111 contacts the lower connector 4121, pull the connecting rod 412 and rotate the screw 411 at the same time, so that the lower connector 4121 carries the upper connector 4111 and moves upward through the two stops 4221 at the same time, disengaging from the locking block 42. The upper cover 11 can then be opened, thereby improving the practicality of the device.

[0039] Reference Figure 1-2 The outer surface of the blister packaging box body 1 is provided with an aluminum foil film 3. By adding a layer of special aluminum foil film 3 on the basis of the original blister packaging box body 1, the film has excellent barrier properties, which can further enhance the sealing and stability of the entire packaging system, not only improving the product's shelf life, but also making it more adaptable to harsh outdoor transportation conditions, thereby improving the practicality of the device.

[0040] Working Principle: The packaging box consists of an upper cover 11 and a lower base 12, which are tightly closed by a snap-fit ​​connection. The bottom of the lower base 12 has a customized groove 121 to accommodate different components of the catheter, such as the three-dimensional fixation device and the expansion catheter. When packaging the three-dimensional fixation and expansion catheter for the brain, first confirm that the catheter has been cleaned, disinfected, and is dry. Then, according to the shape and size of the catheter, place it stably in the corresponding groove 121 of the lower base 12. Subsequently, cover it with the upper cover 11 and secure it with the snaps on both sides. During the entire transportation and handling process, even if it encounters a slight collision, the blister packaging box body 1 can effectively absorb external energy and protect the contents from damage by relying on its own hardness and the cushioning effect of the elastic support feet 2. The edge of the groove 121 is equipped with a soft silicone pad 12114, which can be used when inserting the catheter. The surface is gently wrapped to avoid scratches. If the silicone pad 12114 is found to be severely worn, it should be replaced with a new pad in time to maintain the best protective function of the packaging box. In addition, elastic support feet 2 are set at the four corners of the lower base 12 to provide cushioning when impacted. The blister material is made of high-strength PETG material, which has excellent transparency, heat resistance and toughness, and is suitable for making delicate medical product packaging. The silicone pad 12114 is made of medical-grade soft silicone to ensure safety in contact with the human body. Considering that a higher level of moisture and water protection may be required in some cases, a special aluminum foil film 3 is added to the original blister packaging box body 1. This film has excellent barrier properties and can further enhance the sealing and stability of the entire packaging system, which not only improves the shelf life of the product, but also makes it more suitable for harsh outdoor transportation conditions.

[0041] When the upper cover 11 needs to be opened, rotate the screw 411 to move it downwards within the sleeve 41. As the screw 411 moves downwards, it will cause the upper connector 4111 connected to it to extend into the locking block 42. When the upper connector 4111 passes through the two stops 4221, the pressure will cause the two stops 4221 to move away from the upper connector 4111 via the movable rod 422. When the upper connector 4111 contacts the lower connector 4121, pull the connecting rod 412 and rotate the screw 411 at the same time, so that the lower connector 4121, along with the upper connector 4111, moves upwards through the two stops 4221 and disengages from the locking block 42, thus opening the upper cover 11. When the upper cover 11 and the lower seat 12 need to be closed, simply insert the connecting rod 412 into the locking block 42, so that the lower connector 4121 passes through the two stops 4221 and engages.

[0042] This solution uses high-strength PETG material as the main material, combined with customized grooves 121, silicone pads 12114, and elastic support feet 2, to effectively protect the catheter. Users can easily complete the packaging operation by simply following the prescribed steps. Whether for daily storage or long-distance transportation, it ensures the safety of the device. Compared with existing technologies, this solution significantly improves the safety of cranial three-dimensional fixation and guidance dilation catheters during transportation, reduces the damage rate caused by external factors, extends the service life of the device, optimizes the packaging process, simplifies the operation steps, reduces the workload of medical staff, and saves hospitals the additional expenses caused by frequent replacement of damaged devices. The unique material combination and structural design make the packaging box not only strong enough to resist external impacts, but also maintain a low cost advantage, making it easy to promote and apply to more types of precision medical devices.

[0043] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
