Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a multifunctional integrated portable insulin injection pen. Background Art

[0002] An insulin pen is a medical device designed for patients with blood sugar problems to inject insulin. It is usually composed of an insulin pen body, a needle tip and a needle cap. The steps for using its existing structure are as follows: align the needle tip vertically or obliquely with the patient's skin at the injection site, and then insert it into the patient's body. After the injection is completed, pause for about 15 seconds, then pull out the needle tip, then put the needle cap back on the needle tip, manually rotate the needle tip and discard the used needle tip. The use of an insulin pen has many benefits. On the one hand, it saves patients the tedious process of extracting insulin from an insulin bottle with a syringe; on the other hand, it avoids the embarrassment of patients injecting insulin in public places, and also provides great convenience for patients with poor eyesight or even blindness to inject insulin.

[0003] China Utility Model Patent Publication No.: CN211461588U, discloses: an insulin pen, in which the refill can be easily drawn out of the pen case by pressing the pen clip, and insulin can be repeatedly added to the refill to achieve the effect of repeated use, thereby reducing the patient's medical costs; when the insulin pen is not in use, the needle exposed to the outside can be returned to the pen case by pressing the pen clip, avoiding the safety hazard of hurting the hands. However, although the insulin pen is designed with a retractable structure for the needle, it is not designed with a fool-proof design for the needle. When the patient does not replace the used needle for the second injection in order to save costs, it is easy to cause infection, etc., and the insulin pen does not integrate the insulin pen and the blood sugar testing instrument, so it is easy to use additional instruments for testing when testing blood sugar. When the patient travels, he needs to carry more instruments, which makes the overall portability poor. Summary of the invention

The multifunctional integrated portable insulin injection pen, through the cooperation of the length of the pen cover and the pen core frame and the connector, when the needle and the needle cover are located outside the pen core frame, the needle cannot be installed, thus avoiding the reuse of the needle when injecting again, thereby avoiding bacterial infection or contamination;

[0028] 4. When inserting or removing the needle of the multifunctional integrated portable insulin injection pen, the user can press the fixed block with his fingers to deform the second spring, and then move the fixed block away from the limit groove, release the limit on the pull plate, and place the needle inside or remove the needle, so as to avoid the entire insulin pen being placed in a suitcase or backpack, which may easily cause the pull plate to loosen and cause the unused needle to fall out, thereby causing contamination and affecting subsequent use.

When traveling, the blood glucose can be measured quickly. At the same time, the insulin pen and the blood glucose measuring component 17 can be disassembled to improve the diversity. The battery 1704 provides power support for the entire system to ensure that each component can operate normally. The circuit board 1705 serves as a core control unit and can coordinate and manage the workflow of each module. The processing and transmission module 1706 can process the measurement data and transmit it to an external device or the cloud, which is convenient for users and medical personnel to conduct remote monitoring and management. The display screen 1710 can intuitively display the measurement results, so that users can understand their blood glucose status in time. This integrated design enables the insulin pen to not only have the function of injecting insulin, but also measure blood glucose at the same time. Through the cooperation of the length of the pen cover 6 with the pen core frame 1 and the connector 3, when the needle 4 and the needle cover 5 are located outside the pen core frame 1, the needle 4 cannot be installed, which avoids the reuse of the needle 4 when injecting again, thereby avoiding bacterial infection or contamination. The design of the hanging rod 19 also makes it easy to hang the entire insulin pen in a pocket or other place.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
