Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an implantation tool. Background Art

[0002] A continuous glucose monitoring (CGM) system is a system used to monitor blood sugar levels. Conventional CGM systems insert a sensor into the subcutaneous tissue of the human body. The enzyme on the sensor reacts with the subcutaneous tissue fluid to detect blood sugar levels, and a transmitter transmits the blood sugar levels to a terminal, enabling real-time dynamic monitoring of blood sugar levels. A CGM system only needs to be implanted once and then continuously monitors blood sugar levels via Bluetooth connection, eliminating the pain of frequent needle insertions and complicating the tedious process of traditional blood sugar meters, which can only measure blood sugar once per test.

[0003] In the prior art, during production, components such as the sensor and the transmitter are assembled into a transmitter assembly, which is then mounted on a push piece in the implant tool. When the user uses the implant tool, the push piece is driven by a spring to move, thereby driving the transmitter assembly to move and performing the implant operation. Since the transmitter needs to be separated from the push piece after use, the connection between the transmitter assembly and the push piece is not particularly tight. In order to avoid separation between the transmitter assembly and the push piece before use, in the prior art, a limiting structure is usually provided below the transmitter assembly, so that the transmitter assembly can be supported and limited from the bottom, and separation of the transmitter assembly and the push piece can be avoided when the implant tool accidentally falls.

[0004] However, in the prior art, only a limit structure is provided below the launcher assembly to prevent the launcher assembly from separating from the ejection member. If the implant tool accidentally falls, the drive spring will retract, and the ejection member will move upward under the drive spring, causing the ejection member to separate from the launcher. Utility Model Content

[0005] In the prior art, implant tools only have a limit structure below the emitter assembly to prevent separation between the emitter assembly and the ejection member. If the implant tool accidentally falls, the ejection member is easily driven by the drive spring to move upward, causing separation between the emitter assembly and the ejection member. The present invention provides an implant tool having a limit member above the ejection member. When the implant tool accidentally falls, the limit member can block and limit the ejection member, preventing the ejection member from moving under the drive spring, thereby preventing separation between the ejection member and the emitter assembly.

[0040] The utility model provides an implantation tool, which includes a shell, a push piece, a driving spring, a driving piece, a transmitter assembly, a protective cover, and a limiting piece; the push piece is buckled and arranged in the shell; the driving spring is arranged between the push piece and the shell; the driving piece is arranged on the shell to drive the push piece to disengage from the shell; the transmitter assembly is arranged on the push piece; the protective cover is detachably arranged on the shell and abuts against the bottom of the transmitter assembly; the limiting piece is arranged in the shell and is located above the push piece to block and limit the push piece. The implantation tool is provided with the protective cover and the limiting member. The protective cover can limit the launcher assembly from below the launcher assembly, and the limiting member can limit the ejection member from above the ejection member, thereby limiting the upper and lower position spaces between the launcher assembly and the ejection member, so that there is no space for the launcher assembly and the ejection member to loosen, and when the implantation tool accidentally falls, the ejection member and the launcher assembly can be prevented from separating.

[0041] Please refer to Figures 1 to 4In one embodiment, an implantation tool 100 is provided, comprising a housing 10, an ejection member 20, a drive spring (not shown), a driver 30, a transmitter assembly 40, a protective cover 50, and a stopper 60. The ejection member 20 is snap-fitted within the housing 10, where "snap-fit" refers to a component being connected to another component via a corresponding snap-fit ​​structure, and the two components being able to separate from each other in a corresponding state. The drive spring is disposed between the ejection member 20 and the housing 10, and the driver 30 is disposed on the housing 10 and is used to drive the ejection member 20 to disengage from the housing 10. Specifically, the state of the ejection member 20 is driven by the driver 30, which can transform the ejection member 20 from a "snapped" state to a "disengaged" state, thereby separating the ejection member 20 from the housing 10. The transmitter assembly 40 is disposed on the ejection member 20. When in use, the user operates the driving member 30 to release the ejection member 20, so that the driving spring drives the ejection member 20 to move, and the ejection member 20 drives the emitter assembly 40 to move synchronously, thereby achieving the implantation operation.

[0042] The protective cover 50 is detachably mounted on the housing 10 and abuts against the bottom of the transmitter assembly 40. Figure 1 The angles shown are for reference only. When the implant tool 100 is not in use, the protective cover 50 is connected to the housing 10 and provides an upward support force to the emitter assembly 40 from the bottom of the emitter assembly 40. This prevents the emitter assembly 40 from moving downward and separating from the ejection member 20 in the event of an accident such as a fall, thereby ensuring the reliability of the connection between the emitter assembly 40 and the ejection member 20. When the implant tool 100 is needed, the protective cover 50 is removed. The stopper 60 is disposed within the housing 10 and located above the ejection member 20 to block and limit the ejection member 20. In the event of an accident such as a fall, when the drive spring retracts, the stopper 60 can block the ejection member 20 from above, thereby preventing the ejection member 20 from moving upward and separating from the emitter assembly 40, further ensuring the reliability of the connection between the emitter assembly 40 and the ejection member 20.

[0043] It is understandable that in the prior art, a stopper structure is typically provided only below the launcher assembly to prevent the launcher assembly from separating from the ejection member in the event of a fall or other unexpected situation. However, if the implant tool is dropped, the drive spring retracts, causing the ejection member to move upward under the drive spring, thereby separating the ejection member from the launcher.

[0044] In the implant tool 100 provided in this embodiment, the protective cover 50 and the limit member 60 are provided, and a double support structure is adopted to limit the upper and lower position spaces of the launcher assembly 40 and the ejection member 20. Therefore, when an accident such as falling of the implant tool 100 occurs, the launcher assembly 40 has no downward movement space, and the ejection member 20 has no upward movement space, thereby avoiding accidental separation between the ejection member 20 and the launcher assembly 40, and further improving the connection reliability between the ejection member 20 and the launcher assembly 40.

[0045] It should be noted that directly strengthening the connection between the ejection member and the transmitter assembly (for example, by directly fixing the transmitter to the ejection member, or by providing an additional corresponding structure (for example, by providing a snap-on locking structure)) can also improve the reliability of the connection between the ejection member and the transmitter assembly, thereby preventing the transmitter assembly and the ejection member from separating in the event of an accident such as a fall. However, during subsequent use, since the transmitter needs to be separated from the ejection member, strengthening the connection between the two will cause the user to feel a dragging sensation when the two are subsequently separated, affecting the user's user experience. The implant tool 100 provided in this embodiment can avoid this situation.

[0046] Preferably, in one embodiment, the stopper 60 is a stopper spring arm disposed on the housing 10. The stopper spring arm refers to a component that can elastically deform when subjected to a force and can return to its original state when the force is reduced or eliminated. That is, in this embodiment, the stopper 60 is specifically disposed on the housing 10, and the stopper 60 can move and deform when subjected to a force, thereby making room to avoid interference with other structures in the implant tool 100.

[0047] Preferably, in one embodiment, the limiting member 60 includes a connecting arm 61 and a blocking block 62, wherein the connecting arm 61 is connected to the housing 10, and the blocking block 62 is disposed at the bottom of the connecting arm 61, and the blocking block 62 is located above the ejection member 20. In other words, in this embodiment, the limiting member 60 specifically blocks and limits the ejection member 20 via the blocking block 62.

[0048] Preferably, in one embodiment, the driving member 30 is a driving button disposed on the top of the housing 10. The driving member 30 includes a button body 31, a driving arm 32 connected to the button body 31, and a button cantilever 33. The driving arm 32 is used to drive the ejection member 20 to release from the housing 10, and the button cantilever 33 is used to squeeze the blocking block 62 to deform the limiting member 60. In other words, in this embodiment, the deformation of the limiting member 60 is specifically used to avoid the driving member 30. During the downward pressing of the driving member 30, the button cantilever 33 squeezes the blocking block 62, thereby causing the limiting member 60 to deform and give way.

[0049] Preferably, in one embodiment, a first inclined surface 621 is provided on the top of the blocking block 62, and the first inclined surface 621 is inclined relative to the movable direction of the driving member 30. Figure 2 In the direction angle shown, the movable direction of the driving member 30 is vertical. When the user uses the implant tool 100, by pressing down the driving member 30, the limit member 60 can be deformed and the ejection member 20 can be disengaged. The button cantilever 33 is used to deform the limit member 60 by squeezing the first inclined surface 621. That is to say, in the process of pressing down the driving member 30, the button cantilever 33 is in contact with the first inclined surface 621 of the blocking block 62, so that in the gradual pressing process, the button cantilever 33 gradually slides on the first inclined surface 621 and applies force to deform the limit member 60. Through the setting of the first inclined surface 621, it is easier to deform the limit member 60 when the button cantilever 33 squeezes the blocking block 62, and the user can apply force more easily when pressing down the driving member 30. Specifically, in one embodiment, in the housing 10, the limiting member 60 is closer to the center of the housing 10 than the key cantilever 33, so that when the key cantilever 33 is squeezed, the limiting member 60 deforms inward. Of course, in other embodiments, the limiting member 60 can also be arranged away from the center of the housing 10, so that it deforms outward when compressed.

[0050] Preferably, in one embodiment, a second inclined surface 331 is provided at the bottom of the key cantilever 33 to match the first inclined surface 621. The matching of the second inclined surface 331 and the first inclined surface 621 means that the inclination angles of the two are matched. During the downward pressing process of the key cantilever 33, the second inclined surface 331 cooperates with the first inclined surface 621 to expand the contact area between the key cantilever 33 and the blocking block 62, making the force application process more stable.

[0051] Preferably, in one embodiment, the ejection member 20 includes an ejection member body 21, a pushing portion 22, and a snap portion 23, and the pushing portion 22 and the snap portion 23 are respectively arranged on the ejection member body 21. The pushing portion 22 is used to push the driving member 30 to move relative to the shell 10 during assembly, so that the driving member 30 squeezes the elastic cantilever 11 that limits the shell 10, so that the elastic cantilever 11 snaps the snap portion 23. The elastic cantilever 11 refers to a component that can undergo elastic deformation after being subjected to force, and can restore its state when the force is reduced or eliminated. When assembling the ejection member 20, as Figure 1 As shown, before assembling and promoting, described driving member 30 is in the state of pressing down, and after described ejection member 20 is promoted, the end face of described pushing portion 22 will push up to the bottom surface of described driving member 30, and now described ejection member 20 will support described driving member 30 and promote.After described ejection member 20 stops to promote, described ejection member 20 will move downward under the elastic force driving of described driving spring, and just can stop moving downward until described buckle portion 23 contacts described elastic cantilever 11.And because described elastic cantilever 11 is blocked deformation space by described driving member 30, and described elastic cantilever 11 can't be deformed, described elastic cantilever 11 blocks described buckle portion 23, thereby described ejection member 20 is buckled on described housing 10.And when described implantation tool 100 is used, only need user press described driving member 30, now described driving member 30 will give described elastic cantilever 11 room for deformation, allow described elastic cantilever 11 can smoothly retreat deformation, make described ejection member 20 break away from described elastic cantilever 11. By using this structure, the structure of the implant tool 100 can be simplified, the number of parts in the implant tool 100 can be reduced, and the ejection member 20 can be locked and released freely. At the same time, the assembly process can be simplified. During the assembly process, the ejection member 20 can be pushed to complete the installation and positioning of the drive member 30 and the buckle installation between the ejection member 20 and the housing 10, which reduces the assembly difficulty and can better improve the assembly efficiency. At the same time, by using this structure, the ejection member 20 can be buckled in an interlocking form to better ensure stability.

[0052] Specifically, in one embodiment, the pushing portion 22 is located below the driving arm 32 . When the ejection member 20 is assembled, the pushing portion 22 pushes the driving arm 32 to move, so that the driving arm 32 squeezes and limits the elastic cantilever 11 .

[0053] Preferably, in one embodiment, the ejection member 20 further includes an ejection member cantilever 24 disposed on the ejection member body 21, and the limiting member 60 is located above the ejection member cantilever 24. That is, in this embodiment, the limiting member 60 specifically limits the entire ejection member 20 by blocking the ejection member cantilever 24.

[0054] Preferably, in one embodiment, the blocking block 62 is located between the ejection member cantilever 24 and the key cantilever 33. In other words, the key cantilever 33 is located above the ejection member cantilever 24. When the ejection member 20 is assembled, the ejection member cantilever 24 can push the key cantilever 33 to move, so that the driving member 30 is subjected to multiple points of force.

[0055] It is understandable that, before assembly is complete, the ejection member 20 needs to be able to slide and push the driver 30 to interlock, so that the ejection member 20 does not slide down before the driver 30 is triggered. Therefore, during assembly, the ejection member 20 needs to have a certain amount of space to move upward to push the driver 30. After assembly is complete, the upward position of the ejection member 20 needs to be limited to prevent separation between the ejection member 20 and the launcher assembly 40, which creates a contradiction. By configuring the limiting member 60 as a deformable limiting elastic arm, during assembly, the driving member 30 can be pressed downward to cause the limiting member 60 to deform. At this time, the ejecting member 20 can move upward smoothly to push the driving member 30. When the ejecting member 20 pushes the driving member 30 a distance difference, the assembly of the driving member 30 is completed. After the ejecting member 20 moves downward, the limiting member 60 will reset itself due to the loss of the squeezing of the driving member 30, blocking the top of the ejecting member 20, thereby achieving the blocking and limiting of the ejecting member 20 after the assembly is completed.

[0056] Preferably, in one embodiment, the protective cover 50 includes a protective cover body 51 and a support portion 52 disposed within the protective cover body 51. The protective cover body 51 is detachably connected to the housing 10, and the support portion 52 abuts against the sealing tube 41 of the transmitter assembly 40. In other words, in this embodiment, the protective cover 50 is supported below the sealing tube 41 by the support portion 52, thereby supporting and limiting the entire transmitter assembly 40.

[0057] Specifically, in one embodiment, the transmitter assembly 40 includes a sealing tube 41, a transmitter 42, a sensor assembly 43, and an implant needle assembly 44. The sealing tube 41 is detachably mounted on the bottom of the transmitter 42 (or the sensor assembly 43), sealing and protecting the sensor in the sensor assembly 43 and the implant needle in the implant needle assembly 44. When using the implantation tool 100, the user first removes the protective cover 50 from the sealing tube 41. Then, by pressing the actuator 30, the ejection member 20 is disengaged, causing the ejection member 20 to move downward within the transmitter assembly 40. The implant needle in the implant needle assembly 44 then penetrates the skin, and the sensor detection end of the sensor assembly 43 extends beneath the skin, contacting the blood. The transmitter 42 adheres to the skin, completing the implantation process. The ejection member 20 then retracts and separates from the transmitter 42. Simultaneously, the implant needle assembly 44 retracts, withdrawing the implant needle from the skin, ultimately leaving the transmitter 42 and sensor assembly 43 in the body.

[0058] The above is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the scope of protection of the present invention.
