Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to an implantation tool and a method for assembling the implantation tool. Background Technology

[0002] A continuous glucose monitoring (CGM) system is used to monitor blood glucose levels in the human body. Current CGM systems involve implanting a blood 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 blood glucose monitoring. For CGM systems, an implantation tool is an essential component, allowing for the simple and quick insertion of both the sensor and transmitter into the body.

[0003] The existing implantation tool includes a housing, a pusher, a drive button, a transmitter, and a sensor. The pusher is snapped onto the housing, the drive button is located on the housing to drive the pusher to release, the transmitter is detachably located at one end of the housing, and the sensor is snapped onto the pusher.

[0004] In existing implantation tools, the housing, ejector, drive button, and sensor are assembled together during the manufacturing process; the transmitter and housing are shipped separately. When using the implantation tool, the user must first manually detach the transmitter to one end of the housing, then press the drive button to disengage the ejector. The disengaged ejector then inserts the sensor into the transmitter. After the sensor is inserted, it snaps into the transmitter, and simultaneously disengages from the ejector, thus completing the implantation tool's operation.

[0005] However, this connection structure requires numerous mating structures between the ejector and the sensor, between the transmitter and the housing, and between the transmitter and the sensor, resulting in a complex internal structure for the implantation tool. Summary of the Invention

[0006] In existing implantation tools, the transmitter and housing are separate, with the transmitter detachably attached to one end of the housing during use. This necessitates numerous snap-fit ​​structures, complicating the tool's design. Furthermore, users may mistakenly install the transmitter incorrectly. This invention provides an implantation tool where the transmitter is detachably mounted on a pusher component, and the sensor is mounted on the transmitter. This eliminates the need for connecting structures between the sensor and transmitter, the sensor and pusher component, and the transmitter and housing, simplifying the implantation tool. Moreover, the implantation tool is pre-assembled at the factory, allowing users to operate it simply by pressing a drive button. This effectively prevents incorrect transmitter installation and simplifies operation, significantly improving the user experience.

This makes the overall operation simpler, effectively improves the user experience, and also avoids the risk of incorrect installation when the user manually installs the transmitter.

[0053] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] It should be noted that when a component is referred to as being "fixed to", "mounted to", or "set on" another component, it can be directly on or indirectly set on the other component; when a component is "connected" to another component, or when a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0055] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0057] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size should still fall within the scope of the technical content disclosed in this application, provided that they do not affect the effects and purposes that this application can produce.

[0058] This invention provides an implantation tool, comprising a housing, a pusher, a drive button, a transmitter, and a sensor. The housing has a receiving space with an opening at one end. The pusher is housed in the receiving space and snapped onto the housing. The drive button is located on the housing and is used to drive the pusher to disengage from the housing. The transmitter is detachably mounted on the pusher. The sensor is mounted on the transmitter. In this implantation tool, the sensor is directly mounted on the transmitter, and the transmitter is detachably mounted on the pusher. This eliminates the need for mating structures between the pusher and sensor, between the transmitter and housing, and between the transmitter and sensor, simplifying the overall design, reducing the number of parts, and making the overall structure simpler. Furthermore, the implantation tool is assembled with the entire structure ready at the factory. When in use, the user only needs to press the drive button to release the pusher, which will then push out the transmitter and the sensor simultaneously to perform the implantation action. This makes the overall operation simpler, effectively improves the user experience, and also avoids the risk of incorrect installation when the user manually installs the transmitter.

[0059] Please refer to the following: Figures 1 to 6This embodiment provides an implantation tool 100, which includes a housing 10, a pusher 20, a drive button 30, a transmitter 40, a sensor 50, and an implantation needle assembly 60. The housing 10 has a receiving space 12 with an opening 11 at one end. The pusher 20 is received in the receiving space 12 and snapped onto the housing 10. It should be noted that in this embodiment, "snapped onto" means that one component is connected to another through a corresponding snap-fit ​​structure, and the two components can be separated from each other in a certain state. The drive button 30 is disposed on the housing 10, and the drive button 30 is used to drive the pusher 20 to disengage from the housing 10. That is, the change of the state of the pusher 20 is driven by the drive button 30, which can change the pusher 20 from a "snap-fit" state to a "disengaged" state, thereby separating the pusher 20 from the housing 10.

[0060] The transmitter 40 is detachably mounted on the pusher 20, and the sensor 50 is mounted on the transmitter 40. The specific structure of the transmitter 40 detachably mounted on the pusher 20 can be any desired structure, such as a snap-fit ​​or threaded connection, as long as the transmitter 40 is stably fixed to the pusher 20 when the pusher 20 is in the snap-fit ​​state, so that the pusher 20 can move the transmitter 40 accordingly after disengaging; and the transmitter 40 can separate from the pusher 20 after it has moved to its designated position.

[0061] The implantation needle assembly 60 is snapped onto the ejector 20 and passes through the sensor 50. The needle tip of the implantation needle assembly 60 extends out of the sensor 50, facing the opening 11. Therefore, during use, the user presses the drive button 30 to disengage the ejector 20, which then drives the transmitter 40 and the implantation needle assembly 60 to move synchronously. After moving a certain distance, the needle tip of the implantation needle assembly 60 first pierces the body, allowing the sensor 50 to contact the blood. Finally, the transmitter 40 is separated from the housing 10, leaving it on the body, thus completing one use of the implantation tool 100.

[0062] Understandably, in existing implantation tools, the transmitter and housing are separate, with the sensor snapped onto the ejector. When using the implantation tool, the user must first manually detach the transmitter to one end of the housing, then press the drive button to release the ejector. The released ejector then inserts the sensor into the transmitter. To ensure smooth docking between the sensor and transmitter, a snap-fit ​​structure is provided between them. When the ejector is not detached and when it moves the sensor, the snap-fit ​​structure on the ejector secures the sensor. Once the sensor is inserted into the transmitter, the snap-fit ​​structure on the ejector needs to disengage from the sensor. Simultaneously, a snap-fit ​​structure is also provided between the sensor and transmitter. When the sensor is inserted into the transmitter, the snap-fit ​​structure on the transmitter secures the sensor, thus ensuring a stable connection between the sensor and transmitter. Furthermore, a corresponding mating structure is required between the housing and the transmitter to ensure the transmitter can successfully receive the sensor. Therefore, existing implantation tools require a large number of structures and parts, resulting in a complex internal structure. This not only increases the difficulty of manufacturing and processing, but also, due to the numerous mating structures, requires higher precision in the installation positions of each component, which can easily affect the stability of the implantation tool.

[0063] In the implantation tool 100 provided in this embodiment, the transmitter 40 is directly and detachably mounted on the pusher 20, and the sensor 50 is directly mounted on the transmitter 40. This eliminates the need for corresponding snap-fit ​​structures between the sensor 50 and the transmitter 40, or between the sensor 50 and the pusher 20, and also eliminates the need for corresponding mating structures between the housing 10 and the transmitter 40. This simplifies the overall structure, reduces the number of components and parts, lowers manufacturing difficulty, and reduces the accuracy requirements for installation position, thus better ensuring the stability of the implantation tool 100 during use. Furthermore, the implantation tool 100 is pre-assembled at the factory, meaning the transmitter 40 and sensor 50 are assembled during production. Users only need to press the drive button 30 to use the implantation tool 100, effectively preventing incorrect transmitter installation and simplifying operation, thus improving the user experience.

[0064] Meanwhile, it is understandable that in existing technologies, transmitters need to be mounted on a housing, thus requiring a relatively large size to ensure proper installation. After use, both the transmitter and sensor remain on the body, and a large transmitter would negatively impact the user experience. However, in the implantation tool 100 provided in this embodiment, the transmitter 40 is detachably mounted on the pusher 20, eliminating the need for further interaction with the housing 10. This allows for a smaller transmitter 40, improving the user experience. Specifically, in this embodiment, the transmitter 40 has a size of φ22.9*3.5MM.

[0065] Preferably, the implantation tool 100 further includes a cannula 70, which is detachably connected to the sensor 50. The portion of the implantation needle assembly 60 extending beyond the sensor 50, facing the opening 11, is located within the cannula 70. Thus, the cannula 70 effectively protects the sensor 50 and the implantation needle assembly 60, preventing damage to them after manufacturing and assembly. Simultaneously, the cannula 70 also effectively isolates external air and humidity, further protecting the sensor 50 and the implantation needle assembly 60.

[0066] Preferably, the implantation tool 100 further includes a base 80, which is threadedly connected to the housing 10 and closes the opening 11. The sleeve 70 is threadedly connected to the sensor 50, and the sleeve 70 is also connected to the base 80. That is, in this embodiment, the detachable connection between the sleeve 70 and the sensor 50 is a threaded connection. The threads between the base 80 and the housing 10, and between the sleeve 70 and the sensor 50, have the same direction of rotation. That is, when the thread between the base 80 and the housing 10 is left-handed, the thread between the sleeve 70 and the sensor 50 is also left-handed; when the thread between the base 80 and the housing 10 is right-handed, the thread between the sleeve 70 and the sensor 50 is also right-handed. Because the base 80 is connected to the sleeve 70, when the user unscrews or removes the base 80, the base 80 will simultaneously rotate the sleeve 70. This allows the user to simultaneously remove the cannula 70 from the sensor 50 when removing the base 80 from the housing 10. The base 80 provides a better seal inside the housing 10, ensuring the waterproof and dustproof performance of the implantation tool 100, while also facilitating the removal of the cannula 70.

[0067] Preferably, the outer surface of the sleeve 70 is provided with a first connecting portion 71, and the interior of the base 80 is provided with a second connecting portion 81 that matches the first connecting portion 71. The first connecting portion 71 and the second connecting portion 81 are interlocked. This structure better ensures the reliability of the connection between the base 80 and the sleeve 70, ensuring that the user can simultaneously disassemble the sleeve 70 when unscrewing and disassembling the base 80. Specifically, in this embodiment, the first connecting portion 71 is a groove formed on the outer surface of the sleeve 70, and the second connecting portion 81 is a protrusion formed inside the base 80, with the protrusion correspondingly interlocked in the groove. Of course, in other embodiments, the first connecting portion 71 may also be a protrusion formed on the outer surface of the sleeve 70, and the second connecting portion 81 may correspond to a groove formed inside the base 80. More preferably, the first connecting portion 71 on the outer surface of the sleeve 70 is provided in multiple ways. All the first connecting portions 71 are distributed at equal intervals along the circumference of the sleeve 70 on the outer surface of the sleeve 70, and each first connecting portion 71 is correspondingly fitted with a second connecting portion 81, thereby better ensuring the connection reliability between the base support 80 and the sleeve 70.

[0068] Preferably, the housing 10 includes an outer shell 13 and a hook assembly 14, the hook assembly 14 including a hook 141 and an elastic element 142. The elastic element 142 refers to a component that can undergo elastic deformation under force and return to its original state after the force is reduced or removed. The hook 141 is connected to the outer shell 13 via the elastic element 142, and the ejector 20 is snapped onto the hook 141. The drive button 30 has a locked state where it abuts against the hook 141 to compress the elastic element 142, causing the ejector 20 to snap onto the hook 141; and an unlocked state where it separates from the hook 141, allowing the elastic element 142 to extend and separating the ejector 20 from the hook 141. Specifically, in this embodiment, the elastic element 142 is a spring, and the elastic element 142 extends radially along the outer shell 13. When the drive button 30 is locked, it abuts against the back of the hook 141, preventing the hook 141 from moving towards the center. At this time, the elastic element 142 is compressed, and the pusher 20 is hooked onto the hook 141. When the user presses the drive button 30, it sinks to a certain position, separating from the hook 141 and entering the unlocked state. As the back of the hook 141 loses support, the elastic element 142 extends, causing the hook 141 to move towards the center. After moving a certain distance, the hook 141 separates from the pusher 20, thus disengaging the pusher 20. By utilizing the downward travel of the drive button 30 to convert into the lateral movement of the hook 141, the disengagement of the pusher 20 is achieved, making the drive button 30 more responsive and improving the user experience.

[0069] Preferably, the drive button 30 includes a button body 31 and a stop block 32. The button body 31 is movably disposed on the outer shell 13, and the stop block 32 is connected to the button body 31, and the stop block 32 is used to abut against and separate from the hook 141. That is, in this embodiment, the drive button 30 specifically includes two components. The stop block 32 is used to abut against and limit the hook 141. When the user presses the button body 31, the stop block 32 will sink, which facilitates the user's operation and also better ensures that the drive button 30 abuts against and limits the hook 141.

[0070] Preferably, at least two hook assemblies 14 are provided, arranged in pairs at intervals along the radial direction of the outer casing 13. The stop block 32 is located in the middle of each hook assembly 14 to abut against each hook 141. This structure better balances the force on the ejector 20, preventing lateral deviation and ensuring stability during the ejection process. Specifically, in this embodiment, only two hook assemblies 14 are used as an example. Of course, in other embodiments, the number of hook assemblies 14 can be changed according to actual needs.

[0071] Preferably, the implantation tool 100 further includes a button protection cover 90, which is movably disposed on the housing 10 to cover the drive button 30. Thus, the button protection cover 90 better prevents users from accidentally touching the drive button 30, thereby better ensuring safety. Specifically, in this embodiment, the button protection cover 90 has a flip-top structure; in use, flipping the button protection cover 90 exposes the drive button 30.

[0072] The working principle of the implantation tool 100 is as follows: In use, first unscrew the base 80 to disassemble the base 80 and the sleeve 70. Then, open the button protective cover 90 and press the drive button 30 to lower the stop block 32. When the stop block 32 lowers to a certain position, it separates from the hook 141. Under the action of the elastic element 142, the hook 141 retracts towards the center. After retracting a certain distance, the hook 141 separates from the ejector 20 and disengages. After the ejector 20 disengages, the drive spring on the ejector 20 moves the ejector 20 downwards, thereby setting it on the ejector 20. The transmitter 40 and the implantation needle assembly 60 on the 0 move down synchronously; after the pusher 20 moves down to a certain position, the needle on the implantation needle assembly 60 first pierces the human body, and at the same time the pusher 20 drives the transmitter 40 to continue moving down until it moves to a certain position, the male buckle on the pusher 20 will move to the slide rail end face of the outer shell 13 and stop pushing downward. At this time, the transmitter 40 will be implanted into the human body along with the sensor 50; after the implantation needle assembly 60 pierces the human body, the needle retraction spring on the implantation needle assembly 60 will also drive the needle of the implantation needle assembly 60 to retract upward to complete the needle retraction.

[0073] The implantation tool 100 provided in this embodiment has a simple structure, simplifying the design and reducing the number of structures and parts. The sensor 50 and the transmitter 40 are pre-installed at the factory, and the user only needs to unscrew the base 80 to use it. Simultaneously, the sleeve 70 allows the sensor 50 to be sterilized separately, reducing the sterilization volume. It also allows for a smaller size of the transmitter 40, improving the user experience.

[0074] This embodiment also provides a method for assembling an implantation tool, which includes the following steps:

[0075] S1. Sterilize sensor 50;

[0076] S2. Install the sterilized sensor 50 onto the transmitter 40;

[0077] S3. Assemble the transmitter 40 equipped with sensor 50 together with housing 10, pusher 40, drive button 30 and implantation needle assembly 60 to form the implantation tool 100.

[0078] Understandably, since the sensor needs to enter the human body during subsequent operations, it requires gamma sterilization during production. Current implantation techniques involve first mounting the sensor onto the ejector, assembling the implantation tool into a single unit, and then sterilizing the entire tool. This not only increases the overall sterilization cost but also necessitates the use of gamma-resistant materials or additional gamma-resistant structures in the implantation tool.

[0079] The assembly method of the implantation tool provided in this embodiment first sterilizes the sensor 50 separately, thereby reducing the overall sterilization volume and lowering the cost. It also allows other structures in the implantation tool to be made of materials that can be selected as needed, and there is no need to set up an additional anti-gamma structure in the implantation tool.

[0080] Preferably, the following steps are included before step S1:

[0081] Please refer to the following: Figure 7 S0. The implantation needle in the implantation needle assembly 60 is installed on the sensor 50, and then the sensor 50 is installed in the receiving cavity 210 of the sensor protection mechanism 200. The sensor protection mechanism 200 includes a sleeve 70 and a protective cover 220, which are detachably connected to the sleeve 70 and form a closed receiving cavity 210.

[0082] Understandably, the sensor protection mechanism 200 effectively houses and protects the sensor 50, allowing it to be gamma-sterilized separately during sterilization, eliminating the need to assemble it into the implantation tool for overall sterilization. This structure also reduces the overall size of the sensor 50, providing a basis for selecting the size of the transmitter 40. Furthermore, the sensor protection mechanism 200 allows for free handling during production, effectively protecting the implantation needle and sensor 50 and preventing damage from collisions during manufacturing.

[0083] Specifically, in this embodiment, the sensor 50 and the sleeve 70 are threaded together.

[0084] Preferably, step S1 specifically includes:

[0085] S1. The sensor 50 and the implantation needle housed in the protective mechanism 200 are individually gamma sterilized;

[0086] Step S2 is as follows:

[0087] Please refer to the following: Figure 8 S2. Remove the protective cover 220 from the sleeve 70 and install the portion of the sensor 50 protruding from the sleeve 70 into the groove of the transmitter 40.

[0088] Specifically, before installing the sensor 50, a layer of UV waterproof adhesive is applied to the groove surface of the transmitter 40. Once the sealing end face of the sensor assembly 50 adheres to and cures with the adhesive-sealed end face of the transmitter 40, a sealing layer is formed. This method simultaneously satisfies the sterilization requirements of the sensor 50 and the IPX8 waterproof rating.

[0089] The sensor 50 provided in this embodiment has a threaded structure, which allows the sensor 50 to be threadedly connected to an external structure, facilitating the installation and docking of the sensor assembly 50 with other structures. When sterilizing the sensor 50, it is not necessary to sterilize the sensor 50 as a whole within the implantation tool; instead, the sensor 50 can be individually installed on a separate threaded structure for sterilization, effectively reducing sterilization costs. Simultaneously, the threaded connection also allows for detachable connection of the sensor 50 without affecting its normal use.

[0090] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
