[0021] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:

[0022] Such as Figure 1 and Figure 2As shown in the figure, an injection pen with a ring-shaped indicator light can be used for automatic insulin injection in diabetes. It includes a pen body 1, and a control knob 3 is installed at the tail end of the pen body 1 for performing injection actions and controlling the injection dose. A medicine loading part 2 is arranged at the head end of the pen body 1, and the medicine loading part 2 is used for clamping a cartridge 21. One end of the bottle body of the cartridge 21 is connected to a needle, and the other end is open, and a rubber stopper 22 is fitted at the opening. The liquid medicine in the bottle body can be pushed out of the needle by pushing the rubber stopper 22. A pushing part 4 is arranged inside the middle part of the pen body 1. The pushing part 4 has a push rod 41 coaxially arranged with the pen body 1, a push rod sleeve 42 arranged in cooperation with the push rod 41, and a stepping motor 5 fixed to the pen body 1 through a fixing frame. One end of the push rod 41 is fixed to the execution end of the stepping motor 5, and an external thread is arranged on the outer wall. The inner wall of the push rod sleeve 42 is provided with an internal thread and is in threaded cooperation with the push rod 41. The outer wall of the push rod sleeve 42 has a plane that fits with the pen body 1, and the end far from the stepping motor 5 abuts against the rubber stopper 22 in the cartridge 21. The stepping motor 5 drives the push rod 41 to rotate, so that the push rod sleeve 42 in threaded cooperation with the push rod 41 performs a telescopic movement, thereby pushing the rubber stopper 22 in the cartridge 21 towards the needle, and pushing out the liquid medicine in the cartridge 21. The control knob 3 is connected to an encoder. When the control knob 3 is rotated, the angular information of the control knob 3 read by the encoder will be transmitted to the stepping motor 5 through a flexible circuit board, so that the operator can adjust the medicine pushing amount of the push rod 41 by rotating the control knob 3.

[0023] An indicator light 6 is arranged between the control knob 3 and the pen body 1 for displaying the working state of the current injection pen. Combined with Figure 3 As shown in the figure, the indicator light 6 is set as a ring-shaped structure, and its outer edge surface is a first light-emitting surface 61 that can be observed by the operator from any radial direction along the pen body 1.

[0024] There is a gap for the control knob 3 to move axially between the end face of the control knob 3 adjacent to the pen body 1. The indicator light 6 is arranged in the gap. One end of the indicator light 6 is clamped with the control knob 3, and the other end is set as a second light-emitting surface 62 perpendicular to the axis.

[0025] Specifically, the cross-section of the indicator light 6 passing through the axis is set as an L-shaped step shape. The two perpendicular parts are respectively a light-emitting part and a mounting part 63. The first light-emitting surface 61 and the second light-emitting surface 62 are both arranged in the light-emitting part. A clamping groove 31 is arranged at one end of the control knob 3 close to the pen body 1. The mounting part 63 is clamped in the clamping groove 31 to realize the fixation of the indicator light 6 and the control knob 3. To make the pen body 1 beautiful, the first light-emitting surface 61 has the same diameter as the outer edge surface of the control knob 3.

[0026] As Figure 1 and Figure 2As shown, a charging device 7 is further provided on the pen body 1, including a charging interface opened on one side of the pen body 1 and a charger configured to cooperate with the charging interface. When the charger charges the injection pen, the color and brightness of the indicator light 6 will change according to the charging process.

[0027] On the other side of the pen body 1 relative to the charging device 7, a power switch 8 is provided. The power switch 8 is electrically connected to the indicator light 6 and is used to turn on and off the power of the injection pen. After pressing the power switch 8, the indicator light 6 lights up.
