Technical Field

[0001] The utility model belongs to the technical field of insulin injection, and particularly relates to an auxiliary positioning device for insulin injection. Background Art

[0002] Insulin injection is a medicine for lowering blood sugar in patients with long-term diabetes whose plasma insulin levels are indeed low and who are not satisfactorily controlled by a reasonable diet, physical activity and oral hypoglycemic drugs, or in patients with diabetes who have contraindications to oral hypoglycemic drugs. Glucose and small doses of insulin can be administered intravenously at the same time to promote the body's use of glucose.

[0003] When injecting insulin, diabetic patients need to pinch the skin at the injection site with one hand and insert the insulin pen vertically into the skin. Since the tip area of ​​the insulin pen is small, the injection pen may be inserted at an angle during injection, and then when the insulin pen is pulled out, the needle will be stained with blood, causing bleeding and a nodule at the injection site. For this reason, it is necessary to provide an insulin injection auxiliary positioning device, which adopts a transparent squeezing cover. The skin at the injection site is squeezed and bulged through a circular transparent cover without affecting the user's observation of the needle injection, thereby avoiding the user's pinching of the skin. At the same time, the transparent cover is in contact with the skin to enhance the verticality of the insulin pen during injection and avoid bleeding. Utility Model Content

[0021] Hereinafter, embodiments of the insulin injection auxiliary positioning device of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 An insulin injection auxiliary positioning device according to an embodiment of the utility model is shown, comprising an insulin pen 1: a connecting tube 2 is sleeved on the left end of the insulin pen 1, and a shifting block 12 is fixedly connected to the right ends of the front and rear sides of the connecting tube 2, and three rubber rings 6 are fixedly connected to the left side of the surface of the insulin pen 1, and three arc-shaped card grooves 7 adapted to the rubber rings 6 are provided on the right side of the inner wall of the connecting tube 2. Through the coordinated use of the rubber rings 6 and the arc-shaped card grooves 7, the connecting tube 2 and the insulin pen 1 are connected and fixed, which facilitates the user to quickly assemble and disassemble the connecting tube 2 and the insulin pen 1, and a slidable sliding tube 3 is sleeved on the surface of the connecting tube 2, and a plurality of limiting strips 8 are fixedly connected to the inner wall of the sliding tube 3 in an annular manner, and a plurality of limiting slide grooves 9 are fixedly connected to the surface of the connecting tube 2 in an annular manner, and the limiting strips 8 are slidably connected to the inner cavity of the limiting slide grooves 9, and through the coordination of the limiting strips 8 and the limiting slide grooves 9 The sliding tube 3 is used together to limit and guide the sliding tube 3, thereby preventing the sliding tube 3 from rotating during the sliding process on the surface of the connecting tube 2, and improving the stability of the connecting tube 2 and the sliding tube 3 during use. A transparent cover 4 is fixedly connected to the left side of the sliding tube 3, and two exhaust holes 10 are arranged on the surface of the transparent cover 4. A soft pad 11 is glued to the left side of the transparent cover 4, and the soft pad 11 is a silicone pad. A damping component 5 is arranged on the top and bottom of the connecting tube 2. The damping component 5 includes a fixed block 51 fixedly connected to the right side of the top and bottom of the connecting tube 2, and a sliding pin 52 is fixedly connected to the left end of the fixed block 51. A fixing sleeve 53 is fixedly connected to the right side of the top and bottom of the sliding tube 3. The sliding pin 52 is slidably connected to the inner cavity of the fixing sleeve 53. A spring 54 is sleeved on the surface of the sliding pin 52, and the two ends of the spring 54 are respectively welded to the fixing sleeve 53 and the fixing block 51.

[0023] Working principle: When the utility model is used, the user holds the dial block 12 to sleeve the connecting tube 2 on the left end of the insulin pen 1, and squeezes the rubber ring 6 to engage in the inner cavity of the arc-shaped slot 7, so that the insulin pen 1 and the connecting tube 2 are connected and fixed. Then the user holds the insulin pen 1, aligns it with the injection position, fits the soft cushion 11 with the skin at the injection position, and then pushes the insulin pen 1. During the movement of the insulin pen 1 in the direction of the skin, the connecting tube 2 is driven to slide in the inner cavity of the sliding tube 3. At the same time, the connecting tube 2 drives the sliding pin 52 to slide in the inner cavity of the fixed sleeve 53 through the fixed block 51, so that the spring 54 is compressed. Under the elastic action of the spring 54, the transparent cover 4 squeezes the skin at the injection position, causing the skin at the injection position to bulge. At the same time, the soft cushion 11 is completely fitted with the skin to correct the injection angle of the insulin pen 1. At the same time, the air in the inner cavity of the transparent cover 4 is discharged from the exhaust hole 10 until the needle of the insulin pen 1 is inserted into the user's skin, and the insulin can be injected.

[0024] In summary: the insulin injection auxiliary positioning device, through the coordinated use of the connecting tube 2, the sliding tube 3 and the transparent cover 4, squeezes the bulge of the skin at the injection position and corrects the injection angle, and then injects insulin through the coordinated use of the insulin pen 1 and the damping component 5, thereby achieving the purpose of correcting the injection angle and squeezing the injection position.
