[0002] Insulin is the only hormone in the body that lowers blood sugar, while also promoting the synthesis of glycogen, fat, and protein. Exogenous insulin is primarily used to treat diabetes, and diabetic patients can manage their condition through insulin injections. Insulin pens are widely used in diabetes treatment due to their advantages such as ease of use and portability, precise dosage, and minimal pain.

[0003] However, the existing dosage values ​​are written on a spiral number wheel inside the pen.

[0039] In this embodiment of the disclosure, a digital display insulin pen is provided, comprising a monitoring mechanism and a functional module. The monitoring mechanism detects the liquid content in the reservoir, and the display unit in the functional module displays the liquid content in the reservoir in real time. The display unit is clearer than a spiral digital wheel, allowing patients with eye diseases to know the liquid content in the reservoir in real time.

[0040] See you again Figure 1 In this embodiment of the disclosure, the main body 1 includes a pen body 11 and a pen refill holder 12 connected together. The liquid storage space is disposed in the pen refill holder 12. A needle is disposed at one end of the pen refill holder 12 away from the pen body. A pen cap 13 is also disposed on the outside of the pen refill holder 12.

[0041] See you again Figure 2 In this embodiment of the disclosure, the infusion mechanism 2 includes:

[0042] The system includes a movable element 21 disposed within the liquid storage space, and a power unit 22 disposed at the end of the main body 1 furthest from the needle. The power unit 22 applies power to the movable element 21, causing it to compress the liquid within the liquid storage space. By incorporating the power unit and the compression element, the liquid within the liquid storage space is output through the needle.

[0043] In this embodiment, the movable component 21 is a roller, and the power unit 22 is an adjustment knob. The roller is rotated by adjusting the knob, thereby compressing the liquid in the storage space and achieving the infusion function.

[0044] In this embodiment of the disclosure, the roller is the spiral digital wheel of a conventional insulin pen.

[0045] In this embodiment of the disclosure, the monitoring agency 3 includes:

[0046] The system includes a displacement sensor 31 and a processing unit 32. The displacement sensor 31 monitors the displacement of the drum, and the processing unit 32 determines the liquid content in the storage space based on the displacement of the drum. By monitoring the displacement, the liquid content in the storage space can be determined with high accuracy and is relatively simple.

[0047] Figure 3 This is a schematic diagram of a roller provided as an embodiment of this disclosure. See also: Figure 2 and Figure 3 In this embodiment, the functional module 4 is positioned near the main body 1 of the roller. The displacement sensor 31 is a grating sensor, including a fixed grating 311 and a moving grating 312. The moving grating 312 is spirally wound on the surface of the roller, and the surface of the moving grating 312 is coated with an insulating material layer. The fixed grating 311 is fixed in the functional module 4, and the positions of the fixed grating 311 and the moving grating 312 are correspondingly set in a direction perpendicular to the surface of the main body 1.

[0048] By using a capacitance sensor, when the liquid content in the storage space is adjusted, the adjusting knob drives the drum to rotate, changing the relative positions of the fixed and moving grids, resulting in a change in capacitance. The processing unit receives the signal from the fixed grid and calculates the liquid content in the storage space to determine it. Furthermore, the capacitance sensor is a non-contact sensor, with no friction, requiring only wiring for the moving grid, simplifying wiring and reducing power consumption.

[0049] In this embodiment of the disclosure, the processing unit 32 can be a microprocessor used in digital display vernier calipers.

[0050] In this embodiment of the disclosure, the processing unit 32 is integrated with the functional module 4.

[0052] In this embodiment, the display unit 41 is a rectangular display screen, and the length and width of the display interface of the display unit 41 are greater than or equal to a threshold value, wherein the threshold value ranges from 15 to 30 mm. Using a display unit of the above dimensions can further ensure the display effect.

[0053] In this embodiment of the disclosure, the functional module 4 further includes:

[0054] The voice unit 42 includes a voice switch 421. When the voice switch 421 is activated, the voice unit 42 announces the liquid content in the current storage space via voice. By setting up the voice unit and voice switch, when a user needs to know the liquid content in the storage space, they can activate the voice switch and obtain the liquid content in the storage space via voice, which can further improve the user experience for users with eye diseases.

[0055] In this embodiment, the voice unit 42 is a speaker. Voice broadcasting functionality can be achieved through the speaker.

[0056] In this embodiment of the disclosure, the functional module 4 further includes:

[0057] Zeroing switch 43 is used to reset the liquid content detected by monitoring component 3 to zero. By setting the zeroing switch, if the display is inaccurate, the adjustment knob can be pressed to the initial position, and the displayed value can be updated to zero via the zeroing button.

[0058] In this embodiment of the disclosure, functional module 4 may further include a power supply and a power switch.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
