Description

Technical Field

[0001] The present invention relates to the technical field of insulin injection, and in particular to an insulin injection auxiliary device. Background Art

[0002] Insulin injections are a treatment method that involves injecting insulin subcutaneously into the body, primarily for blood sugar control in patients with diabetes. Insulin is a hormone produced by the beta cells of the pancreas that helps the body use glucose (blood sugar) as an energy source and regulates blood sugar levels. For patients with type 1 diabetes, lifelong insulin therapy is required because their bodies are unable to produce insulin. Patients with type 2 diabetes may also require insulin therapy in certain situations, particularly when other treatments are insufficient to effectively control blood sugar levels.

[0003] Giving an insulin injection typically involves the following steps: Choose the injection site: Common injection sites include the abdomen, outer thigh, outer upper arm, and buttocks. For optimal absorption and to reduce the occurrence of skin problems, the injection site should be rotated. Prepare the insulin and syringe or insulin pen: Choose the appropriate type of insulin (such as rapid-acting, short-acting, intermediate-acting, or long-acting insulin) as recommended by your doctor, and correctly draw up the required dose or set the insulin pen to the correct dose. Disinfect the injection site: Clean the selected injection site with an alcohol swab to reduce the risk of infection. Give the injection: Insert the needle into the skin at an appropriate angle (usually 90 degrees, but a 45-degree angle may be required in children or thin individuals) and slowly inject the insulin. Dispose of used needles and syringes: Dispose of used needles and syringes according to safety guidelines to avoid injury to others.

[0004] Long-term insulin injections require effective rotation of injection sites. Otherwise, adverse reactions such as redness, swelling, nodules, and subcutaneous fat atrophy can occur, impacting insulin absorption and patient compliance. However, existing injection methods often rely on manual determination, making it easy for operators to misremember the injection site. This can lead to repeated injections in the same area within a short period of time, increasing the risk of fat hyperplasia and subcutaneous nodules.

[0005] Therefore, an insulin injection assisting device is needed to solve the above problems. Summary of the Invention

[0006] In order to solve the above problem, that is, to solve the problem that the existing insulin injection method is prone to repeated injections at the same site in a short period of time, increasing the risk of fat hyperplasia and subcutaneous nodules, the present invention provides an insulin injection assist device.

[0007] An insulin injection auxiliary device includes a main body mechanism, which includes a main rod, a rotating rod is rotatably sleeved on the main rod, the top of the main rod is fixedly connected to a dial, a marking mechanism is provided on the rotating rod, the marking mechanism includes a side rod, the top of the side rod is rotatably connected to the top of the rotating rod, an angle adjuster is provided between the side rod and the rotating rod, the bottom end of the side rod is connected to a telescopic rod, the lower end of the telescopic rod is fixedly connected to a marking member, the top surface of the dial is provided with an annular scale line, a positioning pointer is fixedly connected to the dial, and the top of the side rod is fixedly connected to the pointer.

[0008] Specifically, when using, the user takes a standing or sitting position, places the main rod on the navel, places the bottom end of the marking piece on the abdomen, and points the positioning pointer vertically downward, then aligns the pointer with the positioning pointer, and then rotates the rotary rod, which drives the side rod to rotate, and the side rod drives the pointer to rotate. During the rotation of the side rod, the angle of rotation of the side rod can be observed through the pointer. After the side rod rotates to a certain angle, the abdomen is marked with the marking piece. After injecting at the marked position, the next injection is performed, and the above steps are repeated to make the side rod rotate at a larger angle, and mark again. After marking one circle, the telescopic rod is lengthened, and the side rod is rotated to adjust the angle between the side rod and the rotary rod. Then, the rotary rod is continued to be rotated to mark the abdomen.

[0009] Through the setting of the main rod, the injection device can be positioned at the navel, and through the setting of the marking part, the injection position can be marked, which is convenient for subsequent injection work; at the same time, through the setting of the rotating rod, the position of the side rod can be adjusted, thereby changing the position of the mark, and through the setting of the telescopic rod and the angle adjuster, the marking position of the marking part can be further adjusted; the accuracy of the insulin injection device is effectively improved, and the range and point of the mark are expanded.

[0042] Specifically, when using, the user takes a standing or sitting position, places the main rod 11 on the navel, places the bottom end of the marking piece 24 on the abdomen, and points the positioning pointer 14 vertically downward, then aligns the pointer 25 with the positioning pointer 14, and then rotates the rotary rod 12. The rotary rod 12 drives the side rod 21 to rotate, and the side rod 21 drives the pointer 25 to rotate. During the rotation of the side rod 21, the rotation angle of the side rod 21 can be observed through the pointer 25. After the side rod 21 rotates to a certain angle, the marking piece 24 is used to mark the abdomen. After injecting at the marked position, the next injection is repeated to make the side rod 21 rotate at a larger angle and mark again. After marking one circle, the telescopic rod 23 is lengthened and the side rod 21 is rotated to adjust the angle between the side rod 21 and the rotary rod 12. Then, the rotary rod 12 is continued to be rotated to mark the abdomen.

[0043] By setting the main rod 11, the injection device can be positioned at the navel, and by setting the marking part 24, the injection position can be marked, which is convenient for subsequent injection work; at the same time, by setting the rotating rod 12, the position of the side rod 21 can be adjusted, thereby changing the position of the mark, and by setting the telescopic rod 23 and the angle adjuster 22, the marking position of the marking part 24 can be further adjusted; the accuracy of the insulin injection device is effectively improved, and the range and point of the mark are expanded. At the same time, it can be operated with one hand, which is convenient for medical staff and users to use, improves operating efficiency, and shortens injection preparation time.

When the side rod 21 rotates, the edge of the socket 223 contacts the chamfer on the insertion rod 224, causing the insertion rod 224 to deform and move out of the socket 223. When another socket 223 moves to the insertion rod 224, the insertion rod 224 is reinserted into the socket 223.

[0051] Through the setting of the angle adjuster 22, the insertion rod 224 can be inserted into the socket 223 to limit the angle of the side rod 21.
