Because the second restraining arm 905 is provided with the limit bump 906 for restraining the upward movement of the needle seat 902, when the second restraining arm 905 is under the action of the enveloping force of the first restraining arm 904, the limit bump 906 limits the upward movement of the needle seat 902, and the needle withdrawing spring 901 is in a compressed state, however, as the ejection base 2 is separated from the elastic hook arm 101, the ejection spring 3 pushes the ejection base 2 downwards, after the implanted needle carries the sensor 10 to penetrate the skin of a human body, the second restraining arm 905 moves downwards along with the ejection base 2 and is not influenced by the enveloping force of the first restraining arm 904 any more, the needle withdrawing spring 901 in the original compressed state provides the upward acting force for the needle seat 902, the second restraining arm 905 losing the restraining force provided by the first restraining arm 904 moves outwards after receiving the upward acting force of the needle seat 902, and the implanted needle is withdrawn into the supporting body 1 under the acting force of the needle withdrawing spring 901, so as to complete the needle withdrawing action.
It should be noted that, the blood glucose transmitting device according to the embodiment of the present application mainly relates to two parts, namely, an implantation tool part and a signal transmitter 8, so that the implantation tool can not be used after implantation in order to prevent secondary infection, i.e., the implantation tool is a disposable product. When the sensor 10 is implanted, the signal emitter 8 is attached to the skin, and a sticker 808 is arranged at the bottom of the signal emitter 8.
In addition, the second constraint arm 905 cannot return to the inner side of the first constraint arm 904 after needle withdrawal, and the sensing implantation needle 6 cannot be penetrated into the skin of a human body for the second time by pressing the trigger part 4 at the moment, so that the implantation tool for the implantation sensor related to the embodiment cannot be used for the second time, has the advantage of preventing the sensing implantation needle 6 from being secondarily utilized, is beneficial to improving the use standardization of medical equipment and is more sanitary.
