The driving mechanism 200 is located in the accommodating cavity 130, the driving mechanism 200 includes a driving member 210 and a needle fixing member 220, the driving member 210 has a reset hole 2112, a side of the driving member 210 facing away from the trigger end 110 has a first abutting portion, the needle fixing member 220 includes a needle hub 222 and an elastic buckle 221, the needle hub 222 is used for fixing the auxiliary needle 600, the needle hub 222 is aligned with the reset hole 2112, along the second direction (perpendicular to the direction from the trigger end 110 to the implanting end 120), the size of the needle hub 222 is smaller than that of the reset hole 2112, one end of the elastic buckle 221 is connected to the needle hub 222, the other end can abut against the surface of the driving member 210 close to the implanting end 120, and the driving member 210 can move along the first direction (from the trigger end 110 to the implanting end 120) to drive the needle fixing member 220 to move. The needle removing mechanism 300 includes a needle removing member 310 and a first elastic member 320, the needle removing member 310 is fixed on the cavity wall of the accommodating cavity 130, the first elastic member 320 is located between the needle removing member 310 and the needle fixing member 220, the needle removing member 310 has a second abutting portion 311, when the needle fixing member 220 moves towards the needle removing member 310, the needle fixing member 220 can press the first elastic member 320, and the second abutting portion 311 can press the elastic buckle 221, so that the elastic buckle 221 is separated from the first abutting portion, and the needle fixing member 220 extends into the reset hole 2112 and moves in the opposite direction of the first direction.

Specifically, the surface of the driving member 210 facing away from the trigger end 110 includes a first abutting portion, and the driving member 210 is moved toward the implanting end 120 by applying a force to the driving member 210 toward the implanting end 120, so as to drive the auxiliary needle 600 on the needle fixing member 220 to extend out of the accommodating cavity 130 from the implanting end 120, so as to insert the auxiliary needle 600 into the human body, thereby completing the insertion of the auxiliary needle 600. The driver 210 has a reset bore 2112, the needle mount 220 is positioned on a side of the driver 210 adjacent the implanted end 120, the hub 222 of the needle mount 220 is aligned with the reset bore 2112, and the size of the hub 222 is smaller than the size of the reset bore 2112 in the second direction. One end of the elastic buckle 221 is connected to the needle seat 222, and the other end protrudes out of the needle seat 222 along the second direction and abuts against the driving member 210. The needle release member 310 is connected to the wall of the accommodating chamber 130 and located on the moving track of the needle fixing member 220, and when the auxiliary needle 600 moves a certain distance along with the needle fixing member 220 toward the implanting end 120, the needle fixing member 220 can press the first elastic member 320, so that the first elastic member 320 stores elastic potential energy to apply a pushing force toward the triggering end 110 to the needle fixing member 220. When the second abutting portion 311 presses the elastic catch 221 to bias the elastic catch 221 toward the axis 2113 of the reset hole 2112, the elastic catch 221 separates from the first abutting portion. The needle fixing member 220 is pushed by the first elastic member 320 to extend into the reset hole 2112 (as shown in fig. 6), so as to drive the auxiliary needle 600 to move toward the implanting end 120 rapidly, i.e. the auxiliary needle 600 is withdrawn from the human body rapidly. In the whole wearing process, the auxiliary needle 600 can be inserted and withdrawn only by pushing the driving member 210 towards the implanting end 120 by applying force, and the operation is simple and rapid, so that the secondary injury caused by the tension of the wearer is avoided.

Referring to fig. 1 to 4, fig. 3 is a schematic view of the housing and the needle-removing member in fig. 1, fig. 4 is a schematic view of the needle holder and the auxiliary needle in fig. 1, in some embodiments, a surface of the elastic buckle 221 facing away from the axis 2113 of the reset hole 2112 includes a first abutting surface 2211, a distance between the first abutting surface 2211 and the axis 2113 of the reset hole 2112 gradually decreases along the direction from the trigger end 110 to the implanting end 120, a contact surface between the second abutting portion 311 and the elastic buckle 221 is a second abutting surface 3112, and in the second direction, the second abutting surface 3112 is located between a hole wall of the reset hole 2112 and the needle hub 222. Specifically, in the direction from the trigger end 110 to the implantation end 120, the distance between the first abutting surface 2211 and the axis 2113 of the reset hole 2112 gradually decreases, and the second abutting surface 3112 of the second abutting portion 311 is located between the hole wall of the reset hole 2112 and the needle hub 222. Therefore, during the movement of the needle fixing member 220 toward the implanting end 120, the second abutting portion 311 can apply a force to the elastic catch 221 toward the axis 2113 of the reset hole 2112, so that the elastic catch 221 deforms toward the axis 2113 of the reset hole 2112, and the end of the elastic catch 221 near the driving member 210 is deflected to be separated from the surface of the elastic catch 221 near the implanting end 120 of the driving member 210. At this point, the driver 210 no longer applies a force to the needle mount 220 toward the implantation end 120 (neglecting frictional forces between the needle mount 220 and the walls of the reset bore 2112). Therefore, the needle holder 220 is only subjected to the force applied by the first elastic member 320 toward the trigger end 110, so that the needle holder 220 is moved toward the trigger end 110, and the auxiliary needle 600 is withdrawn from the human body.

It should be noted that the axis 2113 of the reset hole 2112 in fig. 1 is not a real structure, but an auxiliary line is made for clearly describing the positional relationship between the first abutting surface 2211 and the second abutting surface 3112 and the reset hole 2112.

Referring to fig. 3 and 4, in some embodiments, the needle removing element 310 further includes two first guiding portions 312 disposed opposite to each other, the second abutting portion 311 is located between the two first guiding portions 312, the first guiding portion 312 has a first guiding groove 3121, the first guiding groove 3121 extends in a first direction, the needle hub 222 is movably clamped in the first guiding groove 3121, and a side surface of the needle hub 222 abuts against a side wall of the first guiding groove 3121.

Specifically, the side surface of the needle holder 222 abuts against the side wall of the first guide groove 3121, so that the needle holder 222 can only move along the first guide groove 3121, and the angle change and the position deviation along the second direction in the moving process of the needle holder 222 are prevented, thereby improving the stability of the needle movement and the position accuracy of the needle when the needle is inserted into the human body.

It is understood that, in practice, in order to allow the needle holder 222 to move in the first guide groove 3121, there is a certain gap between the needle holder 222 and the first guide groove 3121, and a slight angular deviation may occur during the movement of the needle holder 222. Therefore, referring to fig. 1 to 4, in some embodiments, the second guide portion 223 is further connected to the needle holder 222, and the contact surface of the needle holder 220 with the first guide groove 3121 is increased by the side surface of the second guide portion 223, so that the angle variation range of the needle holder 222 is reduced, thereby improving the stability of the movement of the auxiliary needle 600.

In particular, in the above embodiment, the driving member 210 is pushed towards the implanting end 120 to drive the auxiliary needle 600 to extend out of the accommodating cavity 130. Therefore, in order to prevent the needle assisting device from accidentally touching the driving member 210 when not in use, the driving member 210 is pressed towards the implanting end 120, so that the auxiliary needle 600 is prevented from extending out of the accommodating cavity 130. The present embodiment is provided with the locker 410, and when not in use, the locker 410 connects the driving member 210 with the housing 100 to lock the driving member 210, thereby preventing the auxiliary needle 600 from protruding out of the accommodating chamber 130 due to the erroneous touch, and preventing the injury of the person.

Referring to fig. 2, in some embodiments, locking mechanism 400 further includes a second elastic member 420, wherein second elastic member 420 extends in a first direction, one end of second elastic member 420 is connected to housing 100, and the other end is connected to driving member 210, and when locking member 410 is connected to driving member 210, second elastic member 420 can apply a force to driving member 210 toward implanting end 120.

Specifically, it can be known that the present embodiment is provided with the second elastic member 420, the second elastic member 420 is a force applying unit, the second elastic member 420 can be a compression spring, when the locking member 410 is connected to the driving member 210, the compression spring is pressed to apply a pushing force towards the implanting end 120 to the driving member 210, and when the locking member 410 is separated from the driving member 210, the driving member 210 moves towards the implanting end 120 under the pushing force of the compression spring, so that the auxiliary needle 600 rapidly pierces the human body. The driver 210 is prevented from moving by the force of the hand, and the failure of the implantation of the sensor 800 due to the fact that part of the wearer dares not to apply the force to the driver 210 because of the pain when the auxiliary needle 600 is inserted into the human body is prevented.

Referring to fig. 1, in some embodiments, the needle assisting device further includes an upper cover 500, the upper cover 500 is located at the triggering end 110 of the housing 100, the upper cover 500 has a first through hole (not shown), the driving member 210 further includes a first clamping portion 2121, the locking member 410 further includes a sliding portion 411, a connecting portion 412 and a second clamping portion 413, one end of the connecting portion 412 is connected to the sliding portion 411, the other end of the connecting portion is connected to the second clamping portion 413, in the second direction, the second clamping portion 413 protrudes out of the side surface of the connecting portion 412, the connecting portion 412 is disposed through the first through hole, the sliding portion 411 is connected to a surface of the upper cover 500 away from the second elastic member 420, the second clamping portion 413 can be clamped in the first clamping portion 2121, so that the locking member 410 is connected to the driving member 210, and in the direction that the second clamping portion 413 protrudes out of the connecting portion 412, and the size of the connecting portion 412 is smaller than that of the first through hole.

Specifically, under the elastic force of the second elastic member 420, the first engaging portion 2121 and the second engaging portion 413 abut against each other, so that the locking member 410 is connected to the driving member 210. Since the connecting portion 412 protrudes in a direction in which the second clamping portion 413 protrudes from the connecting portion 412, i.e., the second direction, the size of the connecting portion 412 is smaller than that of the first through hole. Therefore, during the using process, the sliding portion 411 can be pushed only along the second direction, so that the second engaging portion 413 is separated from the first engaging portion 2121, and the locking member 410 is separated from the driving member 210, so that the driving member 210 moves toward the implanting end 120 under the elastic action of the second elastic member 420, and the implanting device is simple in structure and convenient to operate.
