[0048] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the effects and purposes that can be achieved by this application.

[0049] The utility model provides a base for an implantation tool, which includes a base body and a support rod; the support rod is arranged on the base body to extend into the implantation tool to support the driving button in the limited implantation tool. The support rod is arranged in the base of the implantation tool, and the support rod can be used to support and limit the driving button, so that the base has a button anti-mistaken touch function, which increases the functionality of the base. And because the base has the button anti-mistaken touch function, there is no need to set up an additional button anti-mistaken touch structure in the implantation tool. When the implantation tool is used, after the base is disassembled, the button can be unlocked, which makes it more convenient for the user to operate the implantation tool, and can better improve the user experience.

[0050] Please refer to Figures 1 to 6 The present embodiment provides a base 10 of an implantation tool, which is used to be installed at the bottom of a housing 20 of an implantation tool 100 and is also used to limit a driving button 30 in the implantation tool 100 to achieve an anti-mistouch function for the driving button 30 .

[0051] The base 10 includes a base body 11 and a support rod 12. The support rod 12 is arranged on the base body 11 to extend into the implant tool 100 to support and limit the driving button 30 in the implant tool 100. That is to say, when the base 10 is installed on the implant tool 100, the support rod 12 extends into the implant tool 100, corresponding to the abutment support of the driving button 30 in the implant tool 100, thereby providing a downward resistance to the driving button 30, thereby limiting the driving button 30, so that the driving button 30 will be resisted by the support rod 12 when it is pressed down, thereby preventing the driving button 30 from being accidentally touched.

[0052] It should be noted that the support rod 12 can directly support the driving button 30, or the support rod 12 can indirectly support the driving button 30 (that is, other structures can be provided between the support rod 12 and the driving button 30, and the support rod 12 does not directly support the driving button 30). That is, when the base 10 is installed on the implant tool 100, the support rod 12 can apply resistance to the driving button 30 to prevent the driving button 30 from being accidentally touched.

[0053] It is understandable that in the implantation tools in the prior art, the function of the base is single, and the base and the button anti-accidental-touch structure are separately arranged. When using the implantation tool, the user not only needs to remove the base, but also needs to operate the button anti-accidental-touch structure to unlock the button, and the operation process is cumbersome.

[0054] The support rod 12 is provided in the base 10 provided in this embodiment, and the support rod 12 is provided to enable the base 10 to have a button anti-mis-touch function, so that the base 10 has more functionality. At the same time, it is also unnecessary to set up an additional button anti-mis-touch structure in the implant tool 100. When the base 10 is disassembled, the drive button 30 can be unlocked simultaneously, making it more convenient and simple for the user to operate the implant tool 100, which can better improve the user's experience.

[0055] Preferably, in one embodiment, the base body 11 includes a bottom wall 111 and a side wall 112 arranged around the bottom wall 111. A support rod fixing seat 1111 is arranged on the bottom wall 111, and the support rod 12 is fixedly installed at the support rod fixing seat 1111. Through this structure, the connection reliability between the support rod 12 and the base body 11 can be better ensured. A detachable structure for detachably connecting with the shell 20 is arranged on the side wall 112. The detachable structure can be any desired structure matching with the shell 20, such as a threaded structure, a hanging platform structure, a snap-on structure, etc., as long as the detachable connection between the base 10 and the shell 20 can be realized.

[0056] Meanwhile, in one embodiment, an implantation tool 100 is also provided, which includes a housing 20, a ejection member 40, a drive button 30, a transmitter 50, a sensor 60, an implantation needle assembly 70 and the base 10. The housing 20 is provided with a receiving space 22 having an opening 21 at one end, and the ejection member 40 is accommodated in the receiving space 22 and snapped on the housing 20. It should be noted that the "snap-on" in this embodiment refers to the connection between one component and another component through a corresponding snap-on structure, and the two components can be separated from each other in a corresponding state. The drive button 30 is arranged on the housing 20, and the drive button 30 is used to drive the ejection member 40 to be released from the housing 20. That is, the change of the state of the ejection member 40 is driven by the drive button 30, and the ejection member 40 can be changed from the "snap-on" state to the "release" state through the drive button 30, so that the ejection member 40 is separated from the housing 20.

[0057] The transmitter 50 is detachably mounted on the ejection member 40, and the sensor 60 is mounted on the transmitter 50. The specific structure of the transmitter 50 being detachably mounted on the ejection member 40 can adopt any desired structure, such as a snap connection, a threaded connection, etc., as long as the transmitter 50 can be stably fixed to the ejection member 40 when the ejection member 40 is in the snap state, so that the ejection member 40 can correspondingly drive the transmitter 50 to move after being released; and when the ejection member 40 moves to the right position, the transmitter 50 can be separated from the ejection member 40.

[0058] The implant needle assembly 70 is buckled on the ejection member 40 and penetrates the sensor 60. Towards the direction of the opening 21, the needle of the implant needle assembly 70 extends out of the sensor 60. Therefore, when in use, after the user releases the ejection member 40 by pressing the driving button 30, the ejection member 40 will drive the transmitter 50 and the implant needle assembly 70 to move synchronously. After moving to a certain distance, the needle of the implant needle assembly 70 will first pierce the human body so that the sensor 60 can contact the human blood accordingly. Finally, the transmitter 50 is separated from the shell 20 and the transmitter 50 is left on the human body, thus completing the use of the implant tool 100.

[0059] The base body 11 is detachably connected to the shell 20 and closes the opening 21, wherein the specific detachable connection structure between the base body 11 and the shell 20 can be selected according to actual needs, such as a threaded structure, a hanging structure, a snap-on structure, etc., and the base body 11 can be removed from the shell 20 when needed.

[0060] The support rod 12 extends into the accommodating space 22 and supports and limits the driving button 30, that is, the support rod 12 is directly or indirectly in contact with the driving button 30. The support rod 12 can provide a supporting force to the driving button 30, thereby forming a resistance for the driving button 30 to be pressed downward. When the base body 11 is not disassembled, the driving button 30 cannot be pressed downward due to the resistance of the support rod 12, thereby realizing the anti-accidental touch function of the implant tool 100.

[0061] Preferably, in one embodiment, the implantation tool 100 further includes a strut conversion member 80, which is slidably disposed in the accommodating space 22, that is, the strut conversion member 80 is disposed in the accommodating space 22, and the strut conversion member 80 can slide in the accommodating space 22 when not limited. The strut 12 is in contact with the strut conversion member 80 for support, and the strut conversion member 80 is in contact with the driving button 30 for support. That is to say, in this embodiment, the strut 12 is in indirect contact with the driving button 30, thereby achieving support and limitation of the driving button 30, and limiting the downward pressure of the driving button 30. Specifically, the strut 12 is in contact with the strut conversion member 80, thereby supporting and limiting the strut conversion member 80, and the strut conversion member 80 is also in contact with the driving button 30, thereby achieving support and limitation of the driving button 30. When the base 10 is removed from the housing 20, the support rod 12 is separated from the support rod conversion member 80, so that the support rod conversion member 80 can slide freely in the accommodation space 22, and the user can press the driving button 30 normally. Specifically, the specific installation position of the support rod conversion member 80 can be on the housing 20 or the ejection member 40.

[0062] Preferably, in one embodiment, the support rod conversion member 80 can be slidably disposed on the ejection member 40. By disposing the support rod conversion member 80 on the ejection member 40, the support rod conversion member 80 can be disposed opposite to the drive button 30, so that the support rod conversion member 80 is located below the drive button 30, thereby simplifying the structure of the support rod 12 and the support rod conversion member 80, making the overall structure simpler, and also allowing the support rod conversion member 80 to more reliably support and limit the drive button 30.

[0063] Preferably, in one embodiment, a limiting step 41 is provided on the ejection member 40. The limiting step 41 is provided corresponding to the strut conversion member 80, and is used to limit the slidable position of the strut conversion member 80 after the strut 12 is separated from the strut conversion member 80. Specifically, after the base 10 is disassembled and the strut 12 is separated from the strut conversion member 80, the strut conversion member 80 can slide downward relative to the ejection member 40, and the distance that the strut conversion member 80 can slide downward will be limited by the limiting step 41. That is, when the strut conversion member 80 slides to a certain distance, it will be blocked by the limiting step 41 and cannot continue to slide down. This structure can better prevent the strut conversion member 80 from falling out of the ejection member 40.

[0064] Preferably, in one embodiment, the strut conversion member 80 includes a conversion member body 81, a first rod body 82, and a second rod body 83. The first rod body 82 is disposed at one end of the conversion member body 81 and abuts against the strut 12. The second rod body 83 is disposed at the other end of the conversion member body 81 and abuts against the drive button 30. The limiting step 41 is disposed corresponding to the conversion member body 81, that is, the limiting step 41 limits the position of the conversion member body 81, thereby limiting the position of the strut conversion member 80.

[0065] Preferably, in one embodiment, a sealing ring 13 is provided on the bottom wall 111, and the sealing ring 13 abuts against the housing 20. By providing the sealing ring 13, the sealing performance between the base 10 and the housing 20 can be better guaranteed, and the components in the housing 20 can be better protected.

[0066] Preferably, in one embodiment, a sealing ring mounting seat 1112 is provided on the bottom wall 111, a sealing ring mounting cavity 1113 is provided in the sealing ring mounting seat 1112, and the sealing ring 13 is arranged in the sealing ring mounting cavity 1112. This structure can better ensure the reliability of the installation of the sealing ring 13, thereby further ensuring the sealing effect.

[0067] Preferably, in one embodiment, the implantation tool 100 further comprises a sleeve 90. The sleeve 90 is mounted on the base 10, and the sleeve 90 is detachably connected to the sensor 60. Towards the opening 21, the portion of the implantation needle assembly 70 extending out of the sensor 60 is located in the sleeve 90.

[0068] Specifically, in one embodiment, the sleeve 90 and the sensor 60 are connected by a hanging platform or a threaded connection, and the base 10 and the housing 20 are connected by a hanging platform or a threaded connection. The unlocking rotation direction between the base 10 and the housing 20, and between the sleeve 90 and the sensor 60 is the same. For example: when the base 10 and the housing 20 are left-handed threads, the sleeve 90 and the sensor 60 are also left-handed threads; when the base 10 and the housing 20 are right-handed threads, the sleeve 90 and the sensor 60 are also right-handed threads. Since the base 10 is connected to the sleeve 90, when the user screws and removes the base 10, the base 10 will synchronously drive the sleeve 90 to rotate. When the user removes the base 10 from the housing 20, the sleeve 90 can also be removed from the sensor 60.

[0069] In the implant tool 100 , the base 10 is used to prevent the driving button 30 from being accidentally touched, and the implant tool 100 has the characteristics of simple overall structural principle, ingenious application, and low functional failure.

[0070] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
