[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0020] Combine Figure 1 、 Figure 2 and Figure 3, an injection auxiliary device for endocrinology clinic, comprising: a pen barrel 1, a refill frame 2 and a pen cover 3; the pen barrel 1 and the refill frame 2 are detachably connected, a needle 4 is provided at one end of the refill frame 2, an auxiliary mechanism 5 is provided on the outer wall of the refill frame 2, the auxiliary mechanism 5 comprises a sliding sleeve 501, a pressure spring 502 and a bottom plate 503, the end of the needle 4 close to the refill frame 2 is fixedly connected to the bottom plate 503, the outer wall of the needle 4 is fixedly connected to the sliding sleeve 501, the outer wall of the sliding sleeve 501 is provided with a sliding groove 504, and a side of the bottom plate 503 close to the needle 4 is fixedly connected to multiple pressure springs 502, the pressure spring 502 is located inside the slide 504, and the slide 504 is slidably connected to the protective cover 505. The protective cover 505 is fixedly connected to the pressure spring 502. The assembly and extrusion dosage of the insulin pen are completed by disassembling the pen barrel 1 and the pen core holder 2. The pen barrel 1 is equipped with a high-precision spiral propulsion dosage adjustment system. Combined with a micro-electromechanical sensor, real-time monitoring and feedback are provided during the rotation and dosage adjustment process, ensuring that the error of each dosage output is controlled within a very small range and can be accurate to 0.01 units, meeting the refined medication needs of different patients;

[0021] The protective cover 505 is connected by sliding in the slide groove 504, and then the pressure spring 502 can be squeezed. When in use, the needle 4 is squeezed to contact the skin, and the bottom plate 503 is connected and fixed.

[0022] Combine Figure 1 The outer wall of the pen barrel 1 is fixedly connected to the feedback controller 6, and the outer side of the protective sleeve 505 is detachably connected to the pen cap 3. The pen cap 3 is located at one end of the injection needle 7. The bottom end of the pen barrel 1 is fixedly connected to the rope buckle 8. The feedback controller 6 has a built-in smart chip and a touch screen control interface, and has voice guidance and gesture recognition functions. The patient can complete the dosage setting, injection and other processes through simple voice commands or intuitive gestures; the device can automatically identify the type of insulin installed, give personalized injection suggestions according to the preset program, and wirelessly connect to the patient's mobile phone APP to upload injection data in real time, which is convenient for doctors to remotely monitor and adjust the treatment plan, greatly simplifying the operation and improving patient compliance. The pen cap 3 protects the pen core holder 2 and needle 4 after use.

[0023] Combine Figure 3 The front end of the needle 4 is fixedly connected to the injection needle 7 to reduce skin tissue damage during puncture and reduce pain. The inside of the pen cap 3 is fixedly connected to a silicone sleeve 9 that matches the injection needle 7. After use, the pen cap 3 contacts the protective sleeve 505, and then the silicone sleeve 9 protects the injection needle 7.

[0024] Working principle: when in use, take out the pen cap 3, then put the insulin into the pen core holder 2, install and fix the pen barrel 1, adjust the dosage control through the pen barrel 1, then aim the auxiliary mechanism 5 at the skin and press it. With the pressure, the protective cover 505 squeezes the pressure spring 502, so that the injection needle 7 is inserted subcutaneously for injection. After the injection is completed, the pressure spring 502 resets the protective cover 505 to form a cover to prevent the user from being afraid of the needle. Then the pen cap 3 and the pen core holder 2 are installed to protect them, and the pen core holder 2 and the needle 4 can be disassembled and reused repeatedly.
