Description

Technical Field

[0001] This utility model relates to the field of medical sensors, and in particular to a blood glucose sensor component package. Background Technology

[0002] Current continuous glucose monitoring (CGM) systems work by implanting a glucose sensor subcutaneously. Enzymes on the sensor react with subcutaneous fluid to detect blood glucose levels, which are then transmitted to a terminal via a transmitter, thus providing continuous glucose readings. It is well-known that the lower the humidity level of the glucose sensor, the more accurate the subsequent blood glucose tests.

[0003] Therefore, in order to ensure safety during the implantation process and the accuracy of sensor measurements, maintaining a low-humidity and dry environment during the storage process of the implanted blood glucose sensor after production to preserve the accuracy of the blood glucose sensor is a challenge in the industry.

[0004] However, in the existing technology, the blood glucose sensor is placed in the slot of the sensor component package together with the guide needle. The humidity of the entire component package is controlled by placing an injection-molded drying block inside the component package to keep the humidity inside the cavity appropriate. Although it can achieve a humidity of <10%RH inside the blood glucose sensor component package cavity, the use of injection-molded drying blocks with high injection molding technology results in high cost. Summary of the Invention

[0032] Implementation Method 1

[0033] like Figures 1-5As shown, this application discloses a blood glucose sensor assembly package 100, including a bottom shell 10, a drying box 20, a protective film 11 for sealing, and an inner support 30 for mounting the blood glucose sensor. The drying box 20 and the inner support 30 are disposed inside the bottom shell 10, and the protective film 11 is attached to the opening 12 of the bottom shell 10. The drying box 20 includes a box body 21, a drying box cover 22, and a desiccant 23 for drying. The desiccant 23 is disposed inside the box body 21, and the drying box cover 22 is disposed at the upper end of the box body 21. The drying box cover 22 is provided with a plurality of vent holes 221 to facilitate the absorption of moisture by the desiccant 23.

[0034] In the above embodiment, the inner support 30 facilitates the installation of the blood glucose sensor 40. The blood glucose sensor assembly package 100 absorbs moisture through the desiccant 23 in the drying box 20 and prevents external moisture from entering through the protective film 11, thereby controlling the humidity of the blood glucose sensor 40. This eliminates the need for injection-molded drying blocks, which are technically difficult to manufacture, and the structure is simple, thus greatly reducing the difficulty and cost of drying technology. To save costs and purify the environment, the desiccant 23 can be a bagged molecular sieve desiccant containing molecular sieve drying particles, and the protective film 11 can be a sterile aluminum-plastic film. The bagged molecular sieve desiccant can also prevent the molecular sieve drying particles (which are fragile) from rubbing against each other during transportation and causing powder to fall and contaminate the entire assembly package. To further save costs, the bagged molecular sieve desiccant can be a molecular sieve desiccant from candy bags.

[0035] Implementation Method 2

[0036] In a preferred embodiment, such as Figures 3-5 As shown, a sliding shaft 213 is provided on the side wall of the box body 21, and a sliding groove 231 corresponding to the sliding shaft 213 is provided on the desiccant 23. The desiccant 23 is slidably connected to the box body 21 through the sliding shaft 213. Preferably, a protruding buckle 222 is provided at the lower end of the drying box cover 22, and a recessed buckle 212 corresponding to the protruding buckle 222 and a U-shaped opening 223 facilitating the installation of the inner support 30 are provided at the upper end of the box body 21. The drying box cover 22 is fastened to the box body 21 through the protruding buckle 222. Preferably, a fixing buckle 211 facilitating installation is provided at the lower end of the box body 21. Preferably, a slot 14 that engages with the fixing buckle 211 is provided inside the bottom shell 10, and the box body 21 is fastened to the bottom shell 10 through the fixing buckle 211.

[0037] In the above embodiment, the desiccant 23 slides into the housing 21 via the sliding shaft 213, facilitating its installation; the desiccant box cover 22 is easily installed onto the housing 21 via the protruding buckle 222; the housing 21 can be engaged with the slot 14 of the bottom shell 10 via the fixing buckle 211, facilitating its installation. Therefore, the assembly of this blood glucose sensor assembly package 100 is very convenient.

[0038] Specifically, the desiccant 23 is first placed into the drying box 20, and then the drying box cover 22 is tightly connected to the recessed fastener 212 on the upper surface of the box body 21 through the protruding fastener to form the drying box 20; then the drying box 20 is placed into the bottom shell 10 through the fixing buckle 211, and then the blood glucose sensor 40 is pre-installed into the bottom shell 10, and then the blood glucose sensor 40 is fixed by the inner bracket 30; then the protective film 11 is heat-sealed at the opening 12 of the bottom shell 10 using a sterile heat sealing machine; after irradiation sterilization, the entire assembly process is completed, and the blood glucose sensor component package 100 is formed.

[0039] Implementation Method 3

[0040] In a preferred embodiment, such as Figure 2 As shown, the side wall of the bottom shell 10 is provided with a positioning element 13, and the side wall of the inner support 30 is provided with a positioning groove 31 corresponding to the positioning element 13. The inner support 30 is engaged with the bottom shell 10 through the positioning element 13. Figure 5 The inner support 30 is mounted on the upper end of the drying box 20 through the U-shaped opening 223. For example... Figure 6 and Figure 7 As shown, the inner support 30 is provided with a sleeve hole 32 for installing the blood glucose sensor 40.

[0041] In the above embodiment, the inner bracket 30 can be easily installed inside the bottom shell 10 via the positioning member 13. The U-shaped opening 223 facilitates the installation of the inner bracket 30, and the sleeve hole 32 facilitates the installation of the blood glucose sensor 40 and makes the blood glucose sensor 40 more stable. To record the humidity inside the bottom shell 10, the blood glucose sensor assembly package 100 also includes a humidity recorder (not shown), which is mounted on the inner bracket 30.

[0042] To test the humidity changes within the blood glucose sensor assembly package of this application, the blood glucose sensor assembly package 100 was divided into groups A, B, and C for humidity testing. The ambient humidity (constant humidity) was 30%.

[0043] like Figures 8-10As shown, after 3 days and 16 hours of testing, it can be demonstrated that the humidity index of the blood glucose sensor component package 100 of this application decreased during the test, and after 18 hours (after 10:19 minutes), the humidity inside the component package remained stable between 4.4% and 1.4%RH, which well meets the industry standard. This indicates that the blood glucose sensor component package 100 can effectively dry moisture and reduce the humidity inside the package, making it very suitable for handling and storing blood glucose sensors.

[0044] In summary, the blood glucose sensor assembly package 100 disclosed in this application absorbs moisture through the desiccant 23 in the drying box 20 and the protective film 11 prevents external moisture from entering, thereby controlling the humidity of the blood glucose sensor 40. Moreover, it eliminates the need for injection-molded drying blocks, which are technically difficult to use, greatly reducing costs and having a simple structure that is easy to assemble.

[0045] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
