Description

Technical Field

[0001] This utility model relates to the field of biomedical engineering industry, specifically to a cap for an analytical substance monitoring system. Background Technology

[0002] Diabetes mellitus is a chronic metabolic disease characterized by high glucose levels, which seriously affects human health. Patients typically manage their condition by monitoring their glucose levels. Currently, continuous glucose monitoring (CGM) is an important glucose monitoring tool that obtains glucose concentration information by implanting sensors under the patient's skin, thereby enabling real-time monitoring of glucose levels in the body.

[0003] In continuous glucose monitoring systems, to ensure safety, the sensors must be sterilized before leaving the factory. The sterilized sensors are then assembled into the application device, which the user can use to implant the sensor subcutaneously. To ensure the sensor remains sterile before implantation, a sensor cap is typically placed around the sensor to form a sealed sterilized assembly. This sterilized assembly is then assembled into the housing of the application device, and the applicator cap is subsequently assembled into the housing to prevent damage to the internal structure before use. In this design, for ease of use, a special connection structure is typically designed between the sensor cap and the applicator cap. This ensures that the sensor cap is not linked to the applicator cap during installation, but allows the sensor cap to be removed along with the applicator cap, enabling simultaneous removal of both the sensor cap and the applicator cap.

[0004] However, this separate design of the sensor cap and the applicator cap has many drawbacks. On the one hand, a complex connection structure needs to be designed between the sensor cap and the applicator cap. This complex structure may increase the difficulty of assembling the various components and is quite cumbersome. On the other hand, this complex structure also has reliability-related issues. Once the connection structure fails (for example, misalignment occurs during assembly), the user may not be able to remove both caps at the same time, and it may even damage the sensor inside the applicator. Summary of the Invention

[0005] This invention is proposed in view of the above-mentioned state of the prior art, and its purpose is to provide a cap for an analytical monitoring system that is highly reliable and easy to use.

[0006] Therefore, the present invention provides a cap for an analyte monitoring system, the analyte monitoring system including a medical device and an application device, the cap including a mating part and a bottom cover, the mating part having a first chamber configured to receive at least a portion of the medical device, the bottom cover being coupled to at least a portion of the application device, and the mating part being integrally formed with the bottom cover.

[0007] In this invention, the cap includes a mating part that mates with a medical device and a bottom cover that mates with an application device. The mating part and the bottom cover are designed as a single, integrally formed structure, eliminating the need for complex connection structures. On one hand, when assembling the analyte monitoring system, the cap can be assembled with the medical device first, and then coupled together to the application device, facilitating assembly and improving reliability during the assembly stage. On the other hand, during user operation, the mating part and bottom cover can be removed together by simply removing the cap, facilitating use and improving reliability during operation. Therefore, this invention provides a cap for an analyte monitoring system that improves overall reliability and ease of use.

[0008] Alternatively, in the cap of the analyte monitoring system of this utility model, the bottom cover may have a mating platform, and the mating part may be disposed on the mating platform.

[0009] Alternatively, in the cap of the analyte monitoring system according to this invention, the coupling base may be embedded in the application device. In this case, embedding the coupling base into the application device increases the contact area between the cap and the application device, making the cap more securely fitted to the application device.

[0010] Additionally, in the cap of the analyte monitoring system according to this invention, optionally, the mating platform is elastic, and when the cap is removed, the connection between the mating part and the mating platform deforms. In this case, the easily deformable characteristic of the mating platform provides space for relative movement between the bottom cover and the mating part, thereby facilitating the removal of the cap.

[0011] Additionally, in the cap of the analyte monitoring system according to this invention, optionally, the cap has a second chamber and a desiccant contained in the second chamber, wherein the first chamber and the second chamber are in communication. This increases the space for receiving the medical device and the space for containing the desiccant.

[0012] Additionally, the cap of the analyte monitoring system according to this invention may optionally include a base plate, which is fixedly connected to the bottom cover to form a first sealing interface. This helps to create a sealed space within the cap.

[0013] Furthermore, in the cap of the analyte monitoring system according to this invention, optionally, the cap has a guided portion, and the medical device has a guide portion configured to guide the guided portion. This allows the cap to couple with the medical device under the guidance of the guide portion.

[0014] Additionally, in the cap of the analyte monitoring system according to this invention, optionally, the application device has a first engagement feature, and the bottom cover has a second engagement feature, the first engagement feature and the second engagement feature cooperating to couple the cap to the application device. This facilitates the coupling of the cap to the application device.

[0015] Additionally, in the cap of the analyte monitoring system according to this invention, optionally, the first engaging feature is an annular opening or guide groove formed on the application device, and the second engaging feature is a protrusion formed on the periphery of the bottom cover, the protrusion being located within the annular opening or guide groove and movable along the extending direction of the annular opening or guide groove. In this case, the cooperation of the first engaging feature and the second engaging feature allows the application device and the bottom cover to be decoupled along a preset path, thereby helping to avoid damage to the sensor in the application device due to misoperation.

[0016] Additionally, in the cap of the analyte monitoring system according to this invention, optionally, the analyte monitoring system further includes a sharp object with a connecting portion located at the portion of the sharp object that protrudes from the bottom surface of the medical device, and the connecting portion is coupled to the mating portion. In this case, by allowing the sharp object to protrude from the bottom surface of the medical device, it is easier for the sharp object to carry the sensor and pierce the subcutaneous tissue during subsequent use. Furthermore, by coupling the connecting portion and the mating portion, it is easier to retain at least a portion of the medical device within the first chamber.

[0017] According to this utility model, a cap for an analytical substance monitoring system that is highly reliable and easy to use is provided. Attached Figure Description

[0034] First, the relevant terms involved in this utility model will be introduced.

[0035] "Decoupling" can refer to removing coupling.

[0036] In some examples, the cap involved in this utility model may also be referred to as a cap body, bottom shell, sealing bottom cap, sealing bottom shell, sealing cover, sensor cap, or sensor cap. Additionally, the analyte monitoring system involved in this utility model may also be referred to as an analyte monitoring device, analyte monitor, analyte concentration information acquisition device, or biomonitoring device, etc. Furthermore, the sensor involved in the examples of this utility model may also be referred to as a monitoring probe, sensing probe, or electrode probe, etc.

[0037] In some examples, for an analyte of glucose, the sensor can be a glucose sensor, and the analyte level can be glucose concentration. However, it is not limited to glucose concentration. For example, by changing the sensing layer of the sensor, other body fluid components besides glucose concentration can also be obtained. These body fluid components can be, for example, one or more of the following: glucose, acetylcholine, amylase, bilirubin, cholesterol, human chorionic gonadotropin, creatine kinase, creatine, creatine anhydride, DNA, fructosamine, glutamine, growth hormone, hormones, blood ketones, lactate, oxygen, peroxides, prostate-specific antigen, prothrombin, RNA, thyroid-stimulating hormone, or troponin.

[0038] For ease of description, some examples below use glucose as the analyte, and correspondingly, the analyte level is the glucose concentration. It should be noted that this does not constitute a limitation of the present invention, and unless there is a contradiction, the relevant descriptions also apply to other analyte levels.

[0039] The analytical substance monitoring system of this utility model will be described in detail below with reference to the accompanying drawings.

[0040] Figure 1 This is an application overview diagram of the analyte monitoring system 1 involved in this utility model example.

[0041] See in some examples Figure 1 The analyte monitoring system 1 may include a medical device 800. In some examples, the medical device 800 may be configured to acquire the host's analyte level.

[0042] In some examples, the medical device 800 can be a sensing device. In some examples, the medical device 800 can be an analyte sensor device that can generate information about specific analytes in bodily fluids, such as by reacting with analytes in bodily fluids and generating analyte information. In this case, by reacting with analytes in bodily fluids, the medical device 800 facilitates the acquisition of analyte information in the bodily fluids. For example, the medical device 800 can be applied to the surface of the host's body and at least partially located under the host's skin to obtain the glucose concentration under the host's skin.

[0043] See in some examples Figure 1 The analyte monitoring system 1 may include an application device 1000. In some examples, the application device 1000 may be configured to apply a medical device 800, which may be applied to a host via the application device 1000, allowing the host to obtain physiological information through the medical device 800 applied to itself. In some examples, the medical device 800 may be applied to a desired location.

[0044] See in some examples Figure 1 The analyte monitoring system 1 may include a reading device 900 that is communicatively connected to the medical device 800. The medical device 800, applied to the host, can transmit the acquired physiological information, for example wirelessly, to the reading device 900, thereby facilitating the host's reading and monitoring of its own physiological information.

[0045] Figure 2 This is a schematic diagram showing the structure of the medical device 800 involved in this utility model example. Figure 3 This is a schematic diagram showing the structure of the sensor 820 involved in this utility model example.

[0046] See in some examples Figure 2 The medical device 800 may include a sensor 820. In some examples, the sensor 820 may be configured to generate analyte level information for the host.

[0047] In some examples, sensor 820 can be placed partially or entirely under the host's skin. In other words, sensor 820 can be placed at least partially under the skin. In some examples, after being placed under the skin, sensor 820 can react with glucose in the subcutaneous tissue fluid to generate glucose information for the host. This allows for the monitoring of physiological information in the subcutaneous tissue fluid.

[0048] See in some examples Figure 3 The sensor 820 may include a tail portion 821, a connecting portion 822, and a contact portion 823.

[0049] In some examples, tail 821 can be used for implantation into the host. In some examples, tail 821 can be elongated.

[0050] In some examples, the tail 821 can also be flexible. This reduces the host's feeling of a foreign object.

[0051] In other examples, the tail 821 can be rigid. This facilitates the placement of the tail 821 under the skin of the host.

[0052] In some examples, after the tail 821 is implanted into the host, the implantation depth can reach the dermis, and the tail 821 can be located in the interstitial tissue of the skin. This enables the sensor 820 to collect glucose information from the interstitial fluid.

[0053] See in some examples Figure 3 The connecting part 822 can connect the tail part 821 and the contact part 823. That is, the tail part 821, the connecting part 822, and the contact part 823 can be connected in sequence. Thus, the analyte level signal generated by the tail part 821 can be transmitted to the contact part 823 through the connecting part 822.

[0054] In some examples, medical device 800 may include an dressing portion 860 (see Figure 2 In some examples, the patch 860 can be applied to the surface of the host's body. In some examples, the patch 860 can also receive glucose information generated by the sensor 820. In some examples, the patch 860 can also provide the sensor 820 with the electrical energy required to acquire physiological information. This allows the sensor 820 to perform continuous monitoring under the host's skin.

[0055] In some examples, the contact portion 823 may have an electrical contact. In some examples, the applicator portion 860 may be electrically connected to the contact portion 823.

[0056] In some examples, the sensor 820 may be supported on the application area 860.

[0057] See in some examples Figure 2 The sensor 820 can extend from the bottom of the dressing portion 860. In some examples, the dressing portion 860 may also include a hole 862 extending from the upper surface to the lower surface, and the axis of the sensor 820 can pass through the hole 862 when the sensor 820 is fitted onto the dressing portion 860. In this case, a sharp object 270 (described later) can penetrate the subcutaneous tissue through the hole, thereby facilitating the placement of the sensor 820 subcutaneously.

[0058] See in some examples Figure 2 The application portion 860 may include a base 830. In some examples, the base 830 may support the sensor 820. In some examples, the sensor 820 may extend beyond the bottom of the application portion 860.

[0059] In some examples, the dressing 860 may also include an electronic device 880 (shown later). The electronic device 880 can receive glucose information generated by the sensor 820. In some examples, the electronic device 880 can further process the glucose information. In other examples, the electronic device 880 can also transmit the received glucose information to an external device, such as the reading device 900 described above. Additionally, the electronic device 880 can also power the sensor 820. In some examples, the contact portion 823 may be configured to connect to the electronic device 880.

[0060] See in some examples Figure 3 The contact portion 823 and the tail portion 821 of the sensor 820 can form an angle of 0° to 90°. This facilitates the electrical connection of the sensor 820 to the electronic device 880 after it is implanted in the host.

[0061] Figure 4 This is a schematic diagram showing the sharp object 270 passing through the base 830, as per an example of this utility model. Figure 4 In this illustration, the structure of the application part 860 has been simplified for clarity, but this should not be construed as a limitation of the present invention.

[0062] See in some examples Figure 4 The analyte monitoring system 1 may include a sharp object 270. In some examples, the sharp object 270 may be configured to penetrate the subcutaneous tissue of a host, carrying at least a portion of a sensor 820.

[0063] See in some examples Figure 4 The sharp object 270 can be mounted on the medical device 800. In some examples, the sharp object 270 can protrude from the bottom surface of the medical device 800. In this case, by having the sharp object 270 protrude from the bottom surface of the medical device 800, it is easier for the sharp object 270 to carry the sensor 820 and insert it subcutaneously during subsequent use.

[0064] See in some examples Figure 4 The sharp object 270 can pass through the base 830 and extend from the bottom of the base 830. In some examples, the tail 821 can be accommodated in the sharp object 270.

[0065] See in some examples Figure 4 The sharp object 270 may have a joint 2741. In some examples, the joint 2741 may be located at the portion of the sharp object 270 that protrudes from the bottom surface of the medical device 800.

[0066] As described above, during the user's use of the analyte monitoring system 1, the sharp object 270 and the sensor 820 can at least partially penetrate the host's subcutaneous tissue. In some examples, the sharp object 270 and the sensor 820 can be sterilized. In some examples, the sensor 820 can be sterilized using radiation sterilization. Radiation sterilization methods can include, for example, electron beam radiation, gamma ray radiation, X-ray radiation, or a combination thereof. This contributes to the health and safety of the host.

[0067] In some examples, after the sharp object 270 and sensor 820 are sterilized, they can be stored in a sealed space. In this case, the sharp object 270 and sensor 820 can remain in a sterile space until the user uses the analyte monitoring system 1.

[0068] Figure 5A This is a schematic diagram showing the structure of the cap 700 involved in this utility model example. Figure 5B It shows Figure 5A A sectional view of the cap along the YY axis at 700°.

[0069] See in some examples Figure 1 or Figure 5A The analyte monitoring system 1 may include a cap 700. In some examples, the cap 700 may be configured to provide a sealed space. The sealed space may seal at least a portion of the medical device 800.

[0070] In some examples, the cap 700 can be coupled to at least one of the medical device 800 and the sharp object 270 to form a sealed space.

[0071] See in some examples Figure 5B The cap 700 may have a first chamber 724. In some examples, the first chamber 724 may receive at least a portion of the medical device 800.

[0072] See in some examples Figure 5B The cap 700 may have a second chamber 771. In some examples, the first chamber 724 may communicate with the second chamber 771. This increases the space for receiving the medical device 800 and the space for accommodating the desiccant 760.

[0073] See in some examples Figure 5B The cap 700 may include a desiccant 760. In some examples, the desiccant 760 may be contained in the second chamber 771. This allows the second chamber 771 to remain dry.

[0074] See in some examples Figure 5A or Figure 5BThe cap 700 may include a mating part 720.

[0075] In some examples, the mating part 720 may be configured to receive at least a portion of the medical device 800.

[0076] In some examples, the mating part 720 may be coupled to the medical device 800. In some examples, the mating part 720 may be removably coupled to the base 830.

[0077] See in some examples Figure 5B The mating portion 720 of the cap 700 may have a first chamber 724. In some examples, the first chamber 724 may be formed by the inner surface of the mating portion 720.

[0078] In some examples, the first chamber 724 can be configured to receive the tail 821 of the sensor 820 to provide a sealed space for the tail 821. This allows for the isolation of external contaminants before the sensor 820 is implanted into the host.

[0079] In some examples, the mating part 720 may be configured to receive at least a portion of the sharp object 270.

[0080] In some examples, the mating portion 720 may be coupled to the sharp object 270. In some examples, the mating portion 720 may be removably coupled to the sharp object 270.

[0081] In some examples, the first chamber 724 can be configured to receive the tail of the sharp object 270 to provide a sealed space for the tail of the sharp object 270. This allows for the isolation of external contamination before the sharp object 270 penetrates the host.

[0082] See in some examples Figure 5A or Figure 5B The cap 700 may include the bottom cap 770.

[0083] See in some examples Figure 5B The bottom cover 770 of the cap 700 may have a second chamber 771. In some examples, the second chamber 771 may be formed by the inner surface of the bottom cover 770.

[0084] In some examples, the mating part 720 can be integrally formed with the bottom cover 770. In this case, the cap 700 includes the mating part 720 that mates with the medical device 800 and the bottom cover 770 that mates with the application device 1000. Designing the mating part 720 and the bottom cover 770 as an integrally formed structure eliminates the need for a complex connection structure between them. On the one hand, when assembling the analyte monitoring system 1, the cap 700 can be assembled with the medical device 800 first, and then coupled together to the application device 1000, which facilitates assembly and improves the reliability of the assembly stage. On the other hand, when the user uses the system, the mating part 720 and the bottom cover 770 can be removed together by removing the cap 700, which facilitates use and improves the reliability of the use stage. In addition, it can help seal the first chamber 724 and the second chamber 771.

[0085] See in some examples Figure 5B The cap 700 may include a base plate 772. In some examples, the base plate 772 may engage with the bottom cover 770. In some examples, the base plate 772 may be fixedly connected to the bottom cover 770 to form a first sealing interface. This facilitates the formation of a sealed space in the cap 700.

[0086] In some examples, the base plate 772 and the bottom cover 770 can be fixedly connected by one or more methods such as adhesives or ultrasonic welding. This helps the base plate 772 to seal the lower interface of the second chamber 771.

[0087] In some examples, the base plate 772 may be made of a transparent material. This allows for easy observation of the positions of the medical device 800 and the sharp object 270 received in the first chamber 724.

[0088] Figure 6 This is a schematic diagram illustrating the sterilization component involved in this utility model example. Figure 7 It shows Figure 6 The diagram shows an enlarged view of region A.

[0089] See in some examples Figure 6 A sharp object 270 passing through the base 830 and coupled with the cap 700 can form a sterilization assembly.

[0090] In some examples, radiation sterilization can be used to sterilize components. Radiation sterilization methods include, for example, electron beam radiation, gamma ray radiation, X-ray radiation, or combinations thereof. This can contribute to the health and safety of the host.

[0091] See in some examples Figure 6After the sterilization components are sterilized, the sensor 820 and the sharp object 270 can be stored in the sealed space provided by the cap 700. In this case, the sensor 820 and the sharp object 270 can remain in a sterile space until the user uses the analyte monitoring system 1.

[0092] In some examples, return to see Figure 2 The base 830 may have a guide portion 836. In some examples, the guide portion 836 may be a guide rail. In some examples, the guide portion 836 may be formed by a recess in the bottom surface of the base 830. In some examples, the guide portion 836 may be a guide groove formed by a recess in the bottom surface of the base 830.

[0093] In some examples, the mating part 720 may have a guided part 730 (see Figure 5A In some examples, the guide portion 836 may be configured to guide the guided portion 730. This allows the cap 700 to be coupled or decoupled from the medical device 800 under the guidance of the guide portion 836. In some examples, the guided portion 730 may move along the guide portion 836.

[0094] See in some examples Figure 2 The guide portion 836 may have a starting position 8361 and a ending position 8362. In some examples, during the coupling of the mating portion 720 with the base 830, the guided portion 730 may be aligned with the starting position 8361 and move relative to the base 830 to the ending position 8362 along the extending direction of the guide portion 836.

[0095] See in some examples Figure 2 The base 830 may have a third limiting portion 837. In some examples, the third limiting portion 837 may be located at the termination position 8362.

[0096] In some examples, the guided portion 730 may be coupled to the third limiting portion 837 (see [reference]). Figure 7 In some examples, when the guided part 730 moves to the termination position 8362, it can be coupled with the third limiting part 837. This allows the mating part 720 to be coupled with the base 830.

[0097] In some examples, the third limiting part 837 may be a protrusion, and the guided part 730 may have a groove.

[0098] In some examples, during the decoupling of the mating part 720 from the base 830, the guided part 730 can be decoupled from the third limiting part 837 and move relative to the base 830 to the starting position 8361 along the extending direction of the guide part 836. This allows the mating part 720 to be decoupled from the base 830.

[0099] In some examples, the guide portion 836 may be an arc with a predetermined curvature. In some examples, the angle corresponding to the predetermined curvature may match a preset angle. For example, the angle corresponding to the predetermined curvature may be equal to a preset angle.

[0100] In some examples, the third limiting part 837 can be coupled or decoupled from the guided part 730 by pre-setting an angle between the relative screwing of the base 830 and the mating part 720.

[0101] See in some examples Figure 6 The engagement portion 2741 can be coupled to the mating portion 720. In this case, coupling the engagement portion 2741 to the mating portion 720 facilitates holding at least a portion of the medical device 800 within the first chamber 724. In some examples, the coupling between the engagement portion 2741 and the mating portion 720 can be a detachable coupling.

[0102] See in some examples Figure 4 or Figure 7 The joint 2741 may have a first joint structure 27411. See some examples. Figure 6 The mating part 720 may have a second joining structure 721.

[0103] In some examples, the first engagement structure 27411 can move along the second engagement structure 721. This facilitates the coupling or decoupling of the mating part 720 from the sharp object 270 along the guide path of the second engagement structure 721.

[0104] In some examples, the first joining structure 27411 may be a groove structure. In some examples, the second joining structure 721 may be an arc-shaped protrusion structure with a predetermined curvature.

[0105] In some examples, the first engagement structure 27411 and the second engagement structure 721 can be coupled or decoupled by a preset angle between the relative screwing of the joint 2741 and the mating part 720.

[0106] Figure 8 It shows Figure 5A The diagram shows an enlarged view of region B.

[0107] See in some examples Figure 8 The mating part 720 may have an inlet groove 723. In some examples, the inlet groove 723 may be configured to guide the engagement part 2741 into or out of the mating part 720 along the axial direction of the mating part 720.

[0108] In some examples, the mating part 720 may have a second rib 722 (see Figure 8In some examples, the second rib 722 may be located at the end of the second engagement structure 721 away from the inlet groove 723.

[0109] In some examples, during the coupling of the joint 2741 and the mating part 720, the first joint structure 27411 can move along the guide groove 723 in a direction close to the second joint structure 721. After the first joint structure 27411 moves to the guide groove 723, it can move relative to the second joint structure 721 in a direction toward the second rib 722 until it abuts against the second rib 722. Thus, the joint 2741 and the mating part 720 can be coupled.

[0110] In some examples, during the decoupling of the joint 2741 and the mating part 720, the first joint structure 27411 can move relative to the second joint structure 721 to the guide groove 723 in a direction away from the second rib 722. After the first joint structure 27411 moves to the guide groove 723, it can move along the guide groove 723 in a direction away from the second joint structure 721 until the joint 2741 and the mating part 720 are decoupled. Thus, the joint 2741 and the mating part 720 can be decoupled.

[0111] In some examples, the coupling or decoupling of the mating part 720 with the base 830 and the coupling or decoupling of the mating part 720 with the joint 2741 can begin and be completed simultaneously.

[0112] See in some examples Figure 6 The analyte monitoring system 1 may include a sealing assembly 500. In some examples, the sealing assembly 500 may include a first sealing element 510 and a second sealing element 520.

[0113] In some examples, the first sealing element 510 may be configured to seal the interface between the medical device 800 and the sharp object 270, and the second sealing element 520 may be configured to seal the interface between the cap 700 and the medical device 800.

[0114] See in some examples Figure 6 The first sealing element 510 can be disposed between the medical device 800 and the sharp object 270, and the second sealing element 520 can be disposed between the cap 700 and the medical device 800.

[0115] In some examples, when the cap 700 is coupled to the sharp object 270, the cap 700 can apply a tensile force to the sharp object 270. In some examples, after being subjected to tensile force, the sharp object 270 can press the first sealing element 510 against the medical device 800. This helps to seal the interface between the medical device 800 and the sharp object 270.

[0116] In some examples, when the medical device 800 is subjected to pressure from the sharp object 270, it can press the second sealing element 520 against the cap 700. This helps to seal the interface between the cap 700 and the medical device 800, that is, to seal the upper interface of the first chamber 724.

[0117] Figure 9 This is a schematic diagram illustrating the pre-assembled module involved in this utility model example.

[0118] As described above, the application unit 860 may also include an electronic device 880. See also [examples of other examples]. Figure 9 The electronic device 880 can be mounted on the base 830.

[0119] See in some examples Figure 9 The application area 860 may also include a cover 840. In some examples, the cover 840 may be fitted onto the base 830.

[0120] In some examples, the cover 840 may have a hole through which a sharp object 270 can pass. This facilitates the fitting of the cover 840 to the base 830.

[0121] In some examples, the top cover 840 can mate with the base 830 to form a first space. In some examples, the electronic device 880 can be housed in the first space. This helps to seal the electronic device 880.

[0122] In some examples, the top cover 840 can be fixed to the base 830. For example, the top cover 840 can be fixed to the base 830 by adhesive bonding or ultrasonic welding. This helps to improve the sealing of the first space.

[0123] See in some examples Figure 9 The outline of the upper cover 840 can be the same as the outline of the base 830. This facilitates sealing of the first space.

[0124] In some examples, a medical device 800 can be formed by assembling the electronic device 880 and the top cover 840 onto the base 830.

[0125] In some examples, the assembled medical device 800, sharp object 270, and cap 700 can be referred to as a pre-assembled module. After the electronic device 880 and cap 840 are assembled, the pre-assembled module can be assembled into the application device 1000.

[0126] Figure 10 This is a schematic diagram showing the coupling of the pre-assembled module and the application device 1000 involved in this utility model example.

[0127] See in some examples Figure 10 The pre-assembled module can be coupled to the application device 1000. In some examples, the coupling of the pre-assembled module to the application device 1000 can mean that the medical device 800, the sharp object 270, and the cap 700 are coupled to the application device 1000.

[0128] See in some examples Figure 10 The cap 700 may be coupled to the application device 1000. In some examples, the bottom cap 770 may be coupled to at least a portion of the application device 1000.

[0129] In some examples, the application device 1000 may include a housing 10 (see [reference]). Figure 10 In some examples, the bottom cover 770 may be removably coupled to the housing 10. In some examples, removing the bottom cover 770 may expose the medical device 800 held in the application device 1000. In some examples, when the bottom cover 770 is removed, a user may use the application device 1000 to apply the medical device 800 to the host.

[0130] In some examples, the bottom cover 770 may have a mating platform 740 (see...) Figure 5A or Figure 5B In some examples, the engagement platform 740 may be embedded with the application device 1000 (see...). Figure 10 In some examples, when the bottom cover 770 is coupled to the application device 1000, the outer surface of the engagement platform 740 can fit against the inner surface of the housing 10. In this case, embedding the engagement platform 740 into the application device 1000 increases the contact area between the bottom cover 770 and the application device 1000, making the bottom cover 770 more securely fitted to the application device 1000.

[0131] Figure 11 This is a schematic diagram showing the structure of the housing 10 involved in this utility model example.

[0132] See in some examples Figure 11 The application device 1000 may have a first engagement feature 191. In some examples, the first engagement feature 191 may be an annular opening or a guide groove formed on the application device 1000.

[0133] In some examples, the housing 10 may include a proximal end portion having a first engagement feature 191. The proximal end portion may be the part of the housing 10 that is close to the host during operation. In some examples, the first engagement feature 191 may extend circumferentially along the housing 10. In some examples, the first engagement feature 191 may be an annular opening formed at the proximal end portion. In some examples, the first engagement feature 191 may be formed as a guide groove at the proximal end portion, such as an annular groove formed as the inner wall of the proximal end portion.

[0134] See in some examples Figure 5A The bottom cover 770 may have a second engagement feature 791. In some examples, the second engagement feature 791 may be a protrusion formed on the periphery of the bottom cover 770.

[0135] See in some examples Figure 5A The second engagement feature 791 may be disposed on the outer surface of the bottom cover 770. In some examples, the second engagement feature 791 may be disposed on the outer surface of the engagement platform 740.

[0136] In some examples, the first engagement feature 191 can engage with the second engagement feature 791 to couple the cap 700 to the application device 1000. This facilitates the coupling of the cap 700 to the application device 1000.

[0137] In some examples, the protrusion may be located within an annular opening or guide groove. The protrusion may also be movable along the extension direction of the annular opening or guide groove. In this case, by engaging the first engagement feature 191 with the second engagement feature 791, the application device 1000 and the bottom cover 770 can be decoupled along a preset path, thereby helping to avoid damage to the sensor 820 in the application device 1000 due to misoperation.

[0138] In some examples, the first joining feature 191 may be an arc with a predetermined curvature.

[0139] In some examples, the first engagement feature 191 and the second engagement feature 791 can be decoupled by rotating the bottom cover 770 relative to the housing 10 at a preset angle.

[0140] See in some examples Figure 11 The housing 10 may have a mounting groove 194. In some examples, the mounting groove 194 may be provided at one end of the first engagement feature 191.

[0141] See in some examples Figure 11 The assembly groove 194 may have an engaging portion 1941, which may be provided at one end of the assembly groove 194 near the first engagement feature 191.

[0142] See in some examples Figure 11 The housing 10 may have a limiting protrusion 195. In some examples, the limiting protrusion 195 may be provided at one end of the first engagement feature 191 near the assembly groove 194.

[0143] In some examples, during the coupling of the bottom cover 770 and the housing 10, the second engagement feature 791 can be aligned and enter the mounting groove 194. The second engagement feature 791 moves along the extending direction of the mounting groove 194 and presses the engaging portion 1941 to enter the first engagement feature 191. In some examples, after the second engagement feature 791 enters the first engagement feature 191, the limiting protrusion 195 can restrict the second engagement feature 791 to the end of the first engagement feature 191 near the mounting groove 194. Thus, the bottom cover 770 can be coupled to the housing 10.

[0144] In some examples, housing 10 may have a decoupling groove 193 configured to provide a path for decoupling cap 700 from housing 10, the decoupling groove 193 being located at the end of first engagement feature 191 remote from assembly groove 194. In some examples, decoupling groove 193 may communicate with first engagement feature 191.

[0145] In some examples, during the decoupling of the bottom cover 770 from the housing 10, the second engagement feature 791 can compress the limiting protrusion 195 to move along the extension path of the first engagement feature 191. In some examples, the second engagement feature 791 can move from the end of the first engagement feature 191 near the mounting groove 194 to the end near the decoupling groove 193 and enter the decoupling groove 193, and the second engagement feature 791 can move away from the housing 10 along the extension direction of the decoupling groove 193. Thus, the bottom cover 770 can be decoupled from the housing 10.

[0146] In some examples, housing 10 may have a first indicator 192 (see Figure 11 The bottom cover 770 may have a second indicator 792 (see below). Figure 5A In some examples, the bottom cover 770 is coupled to the housing 10 when the first indicator 192 and the second indicator 792 are aligned. When the analyte monitoring system 1 is removed from the packaging, it can be determined whether the analyte monitoring system 1 has undergone any undesirable morphological changes before being used, based on whether the first indicator 192 and the second indicator 792 are aligned.

[0147] In some examples, during the decoupling of the bottom cover 770 from the housing 10, the second indicator 792 may move relative to the first indicator 192. In some examples, the movement path of the second indicator 792 relative to the first indicator 192 may be an arc with a predetermined curvature.

[0148] In some examples, return to see Figure 5AThe cap 700 may include a first rib 750. In some examples, the first rib 750 may be located on the side of the bottom cover 770. In this case, the first rib 750 makes the contact between the housing 10 and the bottom cover 770 a line contact, which reduces the force required for coupling or decoupling between the housing 10 and the bottom cover 770, thereby facilitating the coupling or decoupling between the housing 10 and the bottom cover 770. In some examples, the first rib 750 may surround the bottom cover 770. In some examples, there may be multiple first ribs 750.

[0149] In some examples, the cap 700 can be decoupled from the medical device 800, the sharp object 270, and the application device 1000 simultaneously.

[0150] In some examples, during the process of rotating the cap 700 relative to the application device 1000 at a preset angle, the guided part 730 can decouple from the third limiting part 837 and move to the starting position 8361, the first engaging structure 27411 can move relative to the second engaging structure 721 in a direction away from the second rib 722 until it enters the guide groove 723, and the second engaging feature 791 can squeeze the limiting protrusion 195 and move along the extension path of the first engaging feature 191 until it enters the decoupling groove 193.

[0151] In some examples, after the cap 700 is rotated at a preset angle relative to the application device 1000, the first engagement structure 27411 can move along the guide groove 723 in a direction away from the second engagement structure 721, and the second engagement feature 791 can move along the decoupling groove 193 in a direction away from the housing 10. Thus, the cap 700 can be removed.

[0152] In some examples, the first engagement feature 191 may be perpendicular to the central axis of the application device 1000, and the first engagement structure 27411 and the second engagement structure 721 may be oblique threads. When the cap 700 is simultaneously decoupled from the medical device 800, the sharp object 270, and the application device 1000, the bottom cover 770 and the mating part 720 have different travel distances along the central axis of the application device 1000.

[0153] In some examples, the mating part 720 may be disposed on the mating base 740 (see Figure 5A In some examples, when the cap 700 is removed, the connection between the mating part 720 and the mating platform 740 may deform.

[0154] In some examples, the mating base 740 may be elastic. In this case, the deformable nature of the mating base 740 provides space for relative movement between the bottom cover 770 and the mating part 720, thereby facilitating the removal of the cap 700.

[0155] As described above, when the cap 700 is removed, the first engagement structure 27411 moves along the second engagement structure 721 to decouple the mating part 720 from the medical device 800, and the second engagement feature 791 moves along the first engagement feature 191 to decouple the bottom cover 770 from the application device 1000. Therefore, in examples where the angles between the second engagement structure 721 and the first engagement feature 191 and the central axis of the application device 1000 are different, different relative movement distances are generated between the mating part 720 and the medical device 800, and between the bottom cover 770 and the application device 1000. In particular, in examples where the movement strokes of the mating part 720 and the bottom cover 770 are different during decoupling, by making the connection between the mating part 720 and the bottom cover 770 deformable, space can be provided for their relative movement, making it easier to remove the cap 700.

[0156] See in some examples Figure 5A or Figure 5B The mating platform 740 may have a wall 741. In some examples, the mating part 720 may be provided on the wall 741. In some examples, the mating part 720 may engage with the bottom cover 770 through the wall 741.

[0157] See in some examples Figure 5B The wall 741 can be parallel to the base plate 772. However, the present invention is not limited to this. The wall 741 can also have an angle with the base plate 772. For example, the angle between the wall 741 and the base plate 772 can be 10 degrees, 20 degrees or 30 degrees.

[0158] In some examples, the elasticity of wall 741 can be changed by altering its thickness. For instance, the elasticity of wall 741 can be increased by reducing its thickness.

[0159] In this invention, the cap 700 includes a mating part 720 that mates with the medical device 800 and a bottom cover 770 that mates with the application device 1000. The mating part 720 and the bottom cover 770 are designed as an integrally formed structure, eliminating the need for complex connection structures between them. On one hand, when assembling the analyte monitoring system 1, the cap 700 can be assembled with the medical device 800 first, and then coupled together to the application device 1000, facilitating assembly and improving reliability during the assembly stage. On the other hand, when the user uses the system, removing the cap 700 allows for the removal of both the mating part 720 and the bottom cover 770, facilitating use and improving reliability during operation. Therefore, a cap 700 for an analyte monitoring system 1 that improves overall reliability and is easy to use is provided.

[0160] Although the present invention has been specifically described above in conjunction with the accompanying drawings and examples, it is to be understood that the above description does not limit the present invention in any way. Those skilled in the art can make modifications and variations to the present invention as needed without departing from the essential spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
