Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a multi-functional insulin pen. Background Art

[0002] An insulin injection pen is a pen-shaped insulin injection device, similar in shape to a fountain pen but slightly larger in size, which can reduce the psychological burden of insulin injection patients. Its internal structure combines insulin and the injection device into one. The insulin liquid medicine is stored in a pen core, and the pen core is placed in a pen core holder and connected to the pen body, while the pen body is an instrument that can adjust the dosage and perform injection. The specially designed disposable needle is thinner and shorter, so the pain caused during injection is very slight. When using, the patient only needs to adjust the dosage button to the required dosage unit, then insert the needle into the subcutaneous tissue, and press the dosage button all the way down to complete the injection.

[0003] At present, there are no visible markings on the insulin injection pens in the market, and insulin pen cores of different dosage forms can be used in the same pen. Hospitals usually make obvious stickers and stick them on the pen for easy identification of different types of insulin. When using two or more different preparations of insulin simultaneously, two or more insulin injection pens need to be prepared. For example, pre-meal insulin and bedtime insulin have completely different mechanisms of action. Therefore, during the use process, it is necessary to emphasize careful verification before injection to ensure the correct implementation of this injection. For patients who inject insulin at home by themselves, there are phenomena such as taking the wrong injection pen, missing an injection, or injecting at the wrong time, which pose great safety hazards to the patients. Each time various dosage forms of insulin are injected, patients need to be reminded to have meals in time and pay attention to symptoms such as hypoglycemic reactions; patients often forget about the storage, expiration date, etc. of insulin and need to be repeatedly emphasized. It takes a lot of time and energy for education, but the effect is not very satisfactory. After each injection, the needle needs to be left in place for 10 seconds before being pulled out, but medical staff and patients often do not execute it properly, affecting the efficacy of insulin.

[0004] In summary, there is an urgent need for a multi-functional insulin pen that can provide guidance when patients use insulin, can achieve automatic injection, and fully ensure the injection time effect. Summary of the Utility Model

[0023] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the drawings of the specification.

[0024] Please refer to the attached Figure 1 and the attached Figure 2 , Figure 1 Assembly schematic diagram of a multi-functional insulin pen of the present utility model; Figure 2 Schematic diagram of the components of a multi-functional insulin pen of the present utility model; A multi-functional insulin pen includes a drive tube 1, a push tube 2, a core sleeve 3, a needle 4, and a protective sleeve 5; the drive tube 1 is a sleeve structure, and a drive assembly 11 is provided therein. Please refer to the attached Figure 3 , Figure 3This is a schematic diagram of a driving tube and a pushing tube of a multifunctional insulin pen of the present utility model. The driving assembly 11 is a threaded rod driven by a stepper motor. The driving tube 1 is movably connected to the outer pushing tube 21 of the pushing tube 2 through the threaded rod. By rotating the threaded rod, the pushing tube 2 is driven to move. It should be understood that the driving assembly 11 is used to realize the movement of the pushing tube 2 and can also be driven by transmission components such as telescopic rods and ball screws, all of which are prior arts.

Install the needle 4 at the end of the cartridge sleeve 3, and adjust the position of the needle 4 through the drive tube 1 so that it is flush with the end of the positioning rod 12. When in use, disinfect the injection site and exhaust the air from the needle 4, then place the positioning rod 12 against the area to be injected, pre-adjust the injection depth, start the drive assembly 11, drive the outer push tube 21 to carry the pen cartridge and the needle 4 downward, and make the needle 4 enter the user's skin. The depth of entry is the preset depth. Then press the upper end of the push tube 2 to send the preset dose of insulin into the skin, and start the drive assembly 11 10 seconds after injection to drive the outer push tube 21 and the needle 4 to retract, completing the automated injection. It should be understood that after the liquid injection is pressed, the control unit on the grip plate 13 can start counting, and the counting can be triggered by a manual button. When in use, the type, dose, and time of the medicine used can be displayed on the display screen; the speaker can broadcast the precautions during injection.

[0026] It should be noted that the multifunctional insulin pen of the present utility model includes a drive tube 1, a push tube 2, a cartridge sleeve 3, a needle 4, and a protective sleeve 5.
