Description

Technical Field

[0001] The utility model relates to the technical field of insulin injection, in particular to a multifunctional insulin injection device. Background Technique

[0002] When injecting insulin in the prior art, there are many tools that can be used, such as insulin needles, insulin pens, insulin pumps, etc.

[0003] This application document mainly improves the insulin pen. The insulin injection pen mainly consists of a cartridge, an injection needle and an injection button. Insulin is stored in the cartridge, and the injection needle is responsible for releasing insulin into the subcutaneous tissue. When the user presses the injection button, the insulin in the cartridge is pushed by an internal mechanical device. The injection needle is not a traditional needle, but a tiny pore through which insulin is rapidly ejected in liquid form. Insulin passes through the pore of the injection needle to form a fine liquid stream, which can quickly penetrate the human epidermis and enter the subcutaneous tissue.

[0004] Insulin injection pens are technically mature in the prior art, easy to use and can accurately adjust the injection dosage each time as needed. However, when using such devices, since insulin injection pens are generally carried by individuals for use outdoors, the injection area should be disinfected with alcohol before use to ensure the injection quality. However, such injection pens in the prior art lack a disinfection function, so additional cotton swabs and disinfection alcohol need to be prepared manually, which is rather troublesome to use. Therefore, in view of this problem, a multifunctional insulin injection device is needed for improvement. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a multifunctional insulin injection device, including an insulin injection pen 1, a syringe 2 is fixedly arranged at the lower end of the insulin injection pen 1, an injection needle 3 is fixedly arranged at the lower end of the syringe 2, a pen cap 4 is movably clamped at the lower end of the insulin injection pen 1, and a disinfection mechanism for disinfecting the injection area is arranged at the lower end of the pen cap 4. The disinfection mechanism includes a fixing ring 5, a protective housing 6, a rubber sleeve 7, and a cotton swab head 8. A fixing ring 5 is fixedly arranged at the lower end of the pen cap 4, a protective housing 6 is arranged on the outer surface of the fixing ring 5, a rubber sleeve 7 is fixedly arranged inside the fixing ring 5 at the lower end of the pen cap 4, and a cotton swab head 8 is fixedly arranged at the lower end of the rubber sleeve 7.

[0021] A buckle 9 is fixedly arranged on the outer surface of the pen cap 4, and the device can be conveniently clamped and fixed in a pocket or other positions through the buckle 9 to ensure the fixing stability of the device;

[0022] The protective housing 6 is movably screwed on the outer surface of the fixing ring 5 through threads. Through screw fixation, the protective housing 6 can be installed or disassembled at any time according to needs to facilitate use or protect the rubber sleeve 7;

[0023] Disinfection alcohol is arranged inside the rubber sleeve 7. Insulin is a protein composed of amino acids. When it encounters alcohol or other disinfectants, protein denaturation may occur. However, due to the fast volatilization characteristic of alcohol compared with other disinfectants, it can quickly volatilize from the skin after disinfection and will not remain on the skin, so it will not affect the biological potency of insulin; Subsequently, alcohol should be prepared inside the rubber sleeve 7 for disinfection;

[0024] A number of through holes 10 are provided between the outer surface of the rubber sleeve 7 and the cotton swab head 8. Through the through holes 10, the disinfection alcohol inside the rubber sleeve 7 can be conveniently extruded to contact the cotton swab head 8. Then, with the injection site as the center, the cotton swab head 8 slowly rotates from the inside outwards to gradually apply the alcohol to the skin surface at the position where injection is required.

[0025] A groove 11 is provided on the outer surface of the protective housing 6. Through the groove 11, the frictional force on the outer surface of the protective housing 6 can be increased, thereby facilitating the rotation of the protective housing 6.

[0026] Working principle: When using this device, before insulin injection is required, do not open the pen cap 4 first. First, open the protective housing 6 by screw thread engagement, so that the rubber sleeve 7 and the cotton swab head 8 are exposed. Then hold the entire device, make the cotton swab head 8 fit on the patient's skin surface, gently press the rubber sleeve 7, so that a part of the alcohol inside the rubber sleeve 7 is extruded and contacts the cotton swab head 8. Subsequently, with the injection site as the center, the cotton swab head 8 slowly rotates from the inside outwards to gradually apply the alcohol to the skin surface at the position where injection is required. In this way, the disinfection operation can be completed. Then, during the process of waiting for the alcohol to volatilize, tighten the protective housing 6 by screw thread, and then remove the pen cap 4 so that the injection needle 3 is exposed for injection. At this time, the alcohol has almost volatilized and injection can be carried out. In this way, this device has complete functions, and an additional disinfection function is added. It can disinfect the injection area before injection and then perform injection. In this way, the disinfection function and the insulin injection pen are integrated together, which is convenient to carry and use and has complete functions.

[0027] Moreover, when this device is used, it is fixed by screw thread engagement. The protective housing 6 can be installed or disassembled at any time according to needs to facilitate use or protect the rubber sleeve 7. In this way, this device is convenient to operate and is easy to promote and use.

[0028] It should be noted that this device is for single use. After the insulin in the syringe 2 is injected, the alcohol stored inside the rubber sleeve 7 is almost used up. Each time the insulin in the syringe 2 is used up, a new device can be used.
