Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device packaging technology, and in particular to a medical supplies packaging structure. Background Technology
[0002] In the medical field, packaging technology plays a crucial role in ensuring that medical supplies (especially implantable or interventional devices) remain sterile before use and in preventing external factors from affecting their performance. The core function of traditional medical packaging is not only to protect devices from mechanical damage or contaminant contact during transportation and storage through physical barriers, but more importantly, to maintain the sterility of devices in a sealed environment for extended periods by combining it with sterilization processes (such as ethylene oxide sterilization and irradiation sterilization). Specifically, packaging typically uses sealed containers (such as trays, bags, or tubular structures) that thoroughly sterilize the internal devices and packaging components before distribution. Subsequently, a sealing process isolates external microorganisms and contaminants, ensuring the sterility of the devices during use (e.g., when a clinician opens the packaging in a sterile environment) and reducing the risk of infection.
[0003] However, existing packaging technologies still have significant limitations for medical devices with special active ingredients. Taking vascular occlusion devices containing PEG (polyethylene glycol) as an example, their packaging design must simultaneously meet the dual requirements of "maintaining sterility" and "protecting the stability of the active ingredient." Currently, while packaging for such devices generally incorporates absorbent silica gel to control humidity (preventing moisture from affecting the device or active ingredient), it lacks protective measures against oxygen sensitivity. Specifically: firstly, the packaging is only partially filled with nitrogen as a replacement gas, rather than completely removing oxygen; secondly, due to the relatively closed structure of the device itself (such as internal porous structures or complex cavities), the replacement efficiency of nitrogen within the packaging is low, making it difficult to reduce the oxygen content to a sufficiently low level (such as below the critical threshold for oxidative degradation of the active ingredient) before sealing.
[0004] The aforementioned defects directly lead to the PEG active ingredient being prone to oxidation reactions with residual oxygen during storage, causing degradation problems such as molecular chain breakage and inactivation of active sites, ultimately affecting the occlusion effect, biocompatibility, or long-term stability of the device. For example, PEG oxidation may generate byproducts such as carboxylic acids and aldehydes, which not only reduce the device's ability to adhere to or seal damaged blood vessels but may also trigger local inflammatory reactions, threatening patient safety. In addition, oxidative degradation can cause irreversible decline in device performance with prolonged storage time, shortening its effective service life, increasing the waste of medical resources, and raising clinical usage risks.
[0005] In summary, for medical devices containing active ingredients (such as PEG), there is an urgent need for a new packaging solution that can maintain a sterile environment, effectively reduce the oxygen content inside the packaging, and prevent the active ingredients from oxidizing and degrading, in order to solve the problem of unstable device performance caused by residual oxygen in the existing technology. Utility Model Content
[0006] This invention provides a medical supplies packaging structure that can reduce the oxygen and moisture content inside the packaging, solve the problem of unstable device performance caused by residual oxygen in the prior art, and accelerate packaging production efficiency.
[0007] This utility model provides a medical product packaging structure, comprising: a packaging box, the packaging box including a bottom shell and a top cover, one side edge of the bottom shell being movably hinged to one side edge of the top cover, the bottom shell having at least one receiving cavity for accommodating medical products and at least one storage slot, the edge of the bottom shell having a plurality of first positioning members, the edge of the top cover having a plurality of second positioning members corresponding one-to-one with the first positioning members, the first positioning member being one of a protruding structure or a recessed structure, the second positioning member being the other of a protruding structure or a recessed structure, the second positioning member being interference-fitted with the first positioning member to close the top cover to the bottom shell, in the closed state of the packaging box, the receiving cavity and the storage slot having an interconnected venting channel; a cleaning agent, the cleaning agent including a dehumidifier and an oxygen absorber, the dehumidifier and the oxygen absorber being contained in the same storage slot or separately in different storage slots, for removing moisture and oxygen from the receiving cavity through the venting channel; and a sealing bag, fitted over the outside of the packaging box and sealing the packaging box.
[0008] Preferably, the storage slot is arranged adjacent to the receiving cavity.
[0009] Preferably, the bottom shell is provided with a first storage groove 104 and a second storage groove 105, the dehumidifier is contained in the first storage groove 104 and the deoxygenator is contained in the second storage groove 105.
[0010] Preferably, the top cover is provided with a first limiting member and a second limiting member, the first limiting member corresponding to the position of the first storage slot 104, and the second limiting member corresponding to the position of the second storage slot 105; when the packaging box is closed, the first limiting member restricts the dehumidifier from falling out of the first storage slot 104, and the second limiting member restricts the deoxygenator from falling out of the second storage slot 105.
[0011] Preferably, the first limiting member and / or the second limiting member are formed by the recess in the top cover.
[0012] Preferably, the first limiting member and / or the second limiting member are deformable components fixed to the top cover.
[0013] Preferably, the top cover is further provided with at least two reinforcing ribs, which surround the receiving cavity and abut against the bottom shell when the packaging box is closed.

[0016] Preferably, the material of the sealed bag is aluminum foil.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention integrates the oxygen absorber and dehumidifier directly into the storage slot inside the packaging box, eliminating the cumbersome steps required for external deoxygenation or dehumidification in traditional packaging (such as separate vacuuming, nitrogen replacement, etc.), simplifying the packaging process, effectively shortening the production cycle, and reducing time and labor costs.
[0019] Through the ventilation channel design inside the packaging box, the oxygen absorber and dehumidifier can come into efficient and continuous contact with the air in the container cavity and the moisture / oxygen on the surface of the medical supplies, accelerating the oxygen adsorption and moisture absorption process, so that the container cavity reaches the preset low oxygen and low humidity environment. Compared with the traditional packaging method that requires long-term static placement or multiple gas replacements, the efficiency of environmental compliance is greatly improved.
[0020] The packaging box achieves a tight seal by interlocking the second positioning component on the edge of the top cover with the first positioning component. Combined with the sealing effect of the external sealing bag, it can effectively prevent moisture and oxygen from the external environment from re-entering. At the same time, the built-in oxygen scavenger and dehumidifier can continuously play a purifying role. Even if trace amounts of oxygen or moisture still penetrate into the packaging, they can still be absorbed in time, ensuring that the cavity maintains a stable low-oxygen and low-humidity state for a long time, avoiding the impact of environmental fluctuations on the performance of medical products.

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0033] This utility model provides a medical product packaging structure; please refer to [link / reference]. Figure 1 The medical supply packaging structure includes a box, a cleaning agent, and a sealing bag. The cleaning agent is placed inside the box, and the sealing bag is placed over the box to seal it. The box includes a bottom shell 100 and a top cover 200. One edge of the bottom shell 100 is hinged to one edge of the top cover 200. The bottom shell 100 has at least one receiving cavity 101 for accommodating the medical supply and at least one storage slot. Multiple first positioning elements 102 are provided at the edge of the bottom shell 100, and multiple second positioning elements 202, corresponding one-to-one with the first positioning elements 102, are provided at the edge of the top cover 200. The second positioning elements 202 are interference-fitted with the first positioning elements 102 to close the top cover 200 to the bottom shell 100. When the box is closed, there is a ventilated channel between the receiving cavity and the storage slot. The cleaning agent includes a desiccant 301 and an oxygen remover 302. The desiccant 301 and the oxygen remover 302 are contained in the same storage tank or in different storage tanks, and are used to remove moisture and oxygen from the accommodating cavity 101 through the ventilation channel.
[0034] Wherein, the first positioning member 102 is one of a protruding structure or a recessed structure, and the second positioning member 202 is the other of a protruding structure or a recessed structure. Please refer to Figure 1 The first positioning element 102 at the edge of the bottom shell 100 is a recessed structure, and the second positioning element 202 at the edge of the top cover 200 is a raised structure.
[0035] In one possible implementation, the storage slot is arranged adjacent to the accommodating cavity 101. Correspondingly, the ventilation channel between the oxygen absorber 302, the dehumidifier 301 and the medical supplies is shortened. This design allows the oxygen absorber 302 and the dehumidifier 301 to come into efficient and continuous contact with the air in the accommodating cavity 101 and the moisture / oxygen on the surface of the medical supplies, accelerating the oxygen adsorption and moisture absorption process and quickly bringing the accommodating cavity 101 into the required low-oxygen and low-humidity environment.
[0036] In one possible implementation, the bottom shell 100 is provided with a first storage slot 104 and a second storage slot 105. The desiccant 301 is contained in the first storage slot 104, and the oxygen scavenger 302 is contained in the second storage slot 105. This embodiment provides separate storage slots for the desiccant 301 and the oxygen scavenger 302. Compared to storing the desiccant 301 and the oxygen scavenger 302 in the same storage slot, this increases the contact area between the desiccant 301 and the oxygen scavenger 302 and the air inside the packaging, thereby improving adsorption efficiency.
[0037] Furthermore, the top cover 200 is provided with a first limiting member 203 and a second limiting member 204. The first limiting member 203 corresponds to the position of the first storage slot 104, and the second limiting member 204 corresponds to the position of the second storage slot 105. When the packaging box is closed, the first limiting member 203 can abut against the desiccant 301 or maintain a gap with the desiccant 301, and the second limiting member 204 can abut against the oxygen absorber 302 or maintain a gap with the oxygen absorber 302. The first limiting member 203 restricts the desiccant 301 from falling out of the first storage slot 104, and the second limiting member 204 restricts the oxygen absorber 302 from falling out of the second storage slot 105. By limiting the desiccant 301 and oxygen absorber 302 with the first limiting member 203 and the second limiting member 204, it is possible to prevent the desiccant 301 and oxygen absorber 302 from falling out during packaging and transportation, thus affecting the product appearance.
[0038] In one possible implementation, the first limiting member 203 and / or the second limiting member 204 are formed by a recess in the top cover 200. For example, the packaging box is manufactured using a vacuum forming process, where the first limiting member 203 and the second limiting member 204 are formed by pressing a mold at corresponding positions on a thermoplastic sheet.
[0039] In another possible implementation, the first limiting member 203 and / or the second limiting member 204 are deformable components fixed to the top cover 200. These deformable components can be sponges, elastic sheets, etc. Taking the packaging box manufactured using a vacuum forming process as an example, columnar sponges can be adhered to corresponding positions on the top cover 200 as the first limiting member 203 and the second limiting member 204, or elastic sheets can be adhered to corresponding positions on the top cover 200 to serve as the first limiting member 203 and the second limiting member 204.
[0040] Furthermore, the top cover 200 is also provided with at least two reinforcing ribs 205. When the packaging box is closed, the reinforcing ribs 205 surround the receiving cavity 101 and abut against the bottom shell 100. The reinforcing ribs 205 are used to increase the strength of the top cover 200, making the packaging box more resistant to compression.
[0041] Furthermore, in order to improve the convenience and operability of removing and placing medical supplies, a guide groove 103 is provided around the receiving cavity 101. The guide groove 103 is connected to the receiving cavity 101. The guide groove 103 can accommodate at least a finger. When a finger slides into the receiving cavity 101 along the guide groove 103, the finger can just pinch the medical supplies in the receiving cavity 101.
[0042] In one possible implementation, both the bottom shell 100 and the top cover 200 are made of plastic and manufactured using a vacuum forming process. A crease 206 is provided at the connection between the top cover 200 and the bottom shell 100, allowing the top cover 200 to fold or unfold along the crease 206 towards the bottom shell 100 to achieve a movable hinge. Of course, other movable hinge methods can also be used between the top shell and the bottom cover, such as connecting the bottom shell 100 and the top cover 200 with a flexible connecting strap, or providing a torsion spring between the bottom shell 100 and the top cover 200.
[0043] In one possible implementation, the sealing bag is made of aluminum foil. Aluminum foil bags have excellent barrier properties, effectively preventing the intrusion of air, moisture, and other external factors; at the same time, aluminum foil bags also have good sealing properties, effectively preventing leakage and contamination of the packaged items. The sealing bag can be sealed using methods such as heat sealing, ultrasonic sealing, or heat-press sealing to achieve a good seal for the packaging box, isolating it from external oxygen and moisture.
[0044] When using the medical supply packaging structure provided in this embodiment to package medical supplies, the medical supplies can be placed in the corresponding receiving slot, and then the top cover 200 is folded towards the bottom shell 100, so that the second positioning member 202 on the top cover 200 is embedded in the first positioning member 102 on the bottom shell 100. Next, pressure is applied to the edges of the top cover 200 and the bottom shell 100 to ensure an interference fit between the second positioning member 202 and the first positioning member 102. Finally, the packaging box containing the medical supplies is placed into a sealed bag and the sealed bag is sealed. Compared with the prior art, the technical effects achieved by this embodiment are as follows:
[0045] (1) The deoxygenating agent and dehumidifying agent are directly built into the storage slot inside the packaging box, which eliminates the cumbersome steps of external deoxygenation or dehumidification treatment required in traditional packaging (such as separate vacuuming, nitrogen replacement, etc.), simplifies the packaging process, effectively shortens the production cycle, and reduces time and labor costs.
[0046] (2) Through the design of the ventilation channel inside the packaging box, the oxygen remover and dehumidifier can come into contact with the air in the cavity and the moisture / oxygen on the surface of the medical supplies in a highly efficient and continuous manner, accelerating the process of oxygen adsorption and moisture absorption. Within 24 hours, the cavity can reach the preset low oxygen (e.g., oxygen content ≤0.5%) and low humidity (e.g., humidity ≤30%RH) environment. Compared with the traditional packaging method that requires long-term static placement or multiple gas replacements, the efficiency of environmental compliance is greatly improved.
[0047] (3) The packaging box achieves a tight seal by interfering with the first positioning part and the second positioning part of the top cover and bottom shell edge. Combined with the sealing effect of the external sealing bag, it can effectively prevent moisture and oxygen from the external environment from invading again. At the same time, the built-in oxygen remover and dehumidifier can continuously play a purifying role. Even if there is still a trace amount of oxygen or moisture in the packaging, it can still be absorbed in time, ensuring that the cavity maintains a stable state of low oxygen and low humidity for a long time, and avoiding the impact of environmental fluctuations on the performance of medical products.
[0048] (4) For medical products containing PEG active ingredients that are sensitive to oxygen / humidity (such as vascular occlusion devices), a low-oxygen and low-humidity packaging environment can significantly inhibit their oxidative degradation reaction (such as oxidative breakage of PEG molecular chains and inactivation of active sites), prevent problems such as reduced occlusion effect and reduced biocompatibility caused by oxidation, and avoid risks such as device expansion and material aging caused by moisture, thereby extending the effective service life of the device and ensuring safety and reliability during clinical use.
[0049] Note that the above description is merely a preferred embodiment of the present invention and the techniques employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
