Description

Technical Field

[0001] The present invention relates to the technical field of insulin injection assistance, and more specifically to an insulin injection assistance device for endocrinology department. Background Art

[0002] As a common disease with a high incidence rate among the population, diabetes has brought severe challenges to the health of the general public. Long-term diabetes and continuous high blood sugar in the body will gradually cause chronic damage to various tissues, affecting key parts such as the eyes, kidneys, heart, blood vessels, and nerves, which will lead to functional disorders and seriously affect the patient's quality of life and even life health. In the clinical treatment of diabetes, insulin injection is currently recognized as the most effective treatment method and is widely used in the daily course management of diabetic patients. Patients use insulin pens to accurately adjust the required injection dose. After strictly disinfecting the skin, select the appropriate angle to inject insulin subcutaneously and stay for at least 10 seconds before removing the needle. Every link in this series of operation processes, especially the precise control of the injection angle and the standardization of the operation, are closely related to the ultimate effect of insulin treatment and directly determine the effectiveness of blood sugar control.

[0003] However, according to the professional guidance of the "Technical Guidelines for Diabetes Drug Injection in China 2021 Edition", when adult patients use shorter needles such as 4mm, 5mm and 6mm for injections, the standard operation should be to insert the needle at a 90° angle to the skin surface, so as to ensure that the drug can be accurately delivered to the appropriate subcutaneous tissue level to achieve the best drug absorption and therapeutic effect; focusing on the actual scenarios of daily insulin injections in the endocrinology department, the problems are clearly presented. In the endocrinology ward, patients have diverse conditions and different physical conditions, and they encounter many difficulties when performing the key process of insulin injection.

[0004] Due to physical discomfort and lack of injection experience, some patients simply rely on their own perception to determine the appropriate injection site on the skin surface. This has poor accuracy and is prone to positioning errors. The injection site is usually not precisely 90 degrees perpendicular to the skin and the insulin is often mistakenly injected into the muscle layer or deviates from the ideal site in the subcutaneous tissue. This seriously hinders the normal absorption of the drug and prevents the insulin from fully exerting its blood sugar-lowering effect.

[0005] At the same time, during the injection preparation stage, due to factors such as tension and physical weakness, the patient's hands often tremble uncontrollably, making it difficult for the injection angle to accurately reach the standard required 90° vertical state. At the same time, it is difficult for medical workers to ensure that the injection is in a 90° vertical state each time when directly using a syringe for injection. This can easily lead to a series of non-standard operational problems, including completely wrong injection sites, skin leakage at the injection site, and intradermal injections instead of subcutaneous injections.

[0006] These frequent irregular operations have brought about a series of negative consequences. On the one hand, they directly reduce the therapeutic effect of insulin, making the expectation of controlling blood sugar levels through injections unfulfilled, and putting disease control in a difficult situation. On the other hand, they also hide huge risks and are likely to cause a series of worrying local adverse reactions at the injection site, such as rapid redness and swelling at the injection site, itching, and the formation of nodules over time. In severe cases, they may even induce infection. Summary of the invention

[0007] In view of the problem in the prior art that injection deviation is easy to occur during self-injection of insulin and injection cannot be performed at a 90-degree angle, the purpose of the present invention is to provide an insulin injection auxiliary device for endocrinology department.

[0008] To solve the above problems, the present invention adopts the following technical solutions:

The lower end of the inner part of the strip groove is rotatably connected with an external gear, the inner side of the external gear is meshed with a linkage mechanism, and the top of the external gear is fixedly connected with a correction frame, which is accommodated in the inner part of the strip groove.

[0011] Optionally, a covering rubber plate is fixedly connected to the outer side of the correction frame, the covering rubber plate covers the outer side of the correction frame, and the outer side of the covering rubber plate is arranged in an arc shape.

[0012] Optionally, a base ring is fixedly mounted on the outer side of the top of the guide tube, and a limiting mechanism is provided on one side of the base ring.

[0013] Optionally, support rods are fixedly installed at equal intervals on the bottom of the base ring, support grooves are opened at equal intervals on the outer side of the shell, the bottoms of the support rods are inserted into the support grooves, and the support rods and the support grooves are slidably connected.

[0014] Optionally, the top of the guide tube passes through the base ring and is fixedly connected to a guide frame, and the side shape of the guide frame is an inverted isosceles trapezoid.

[0015] Optionally, the linkage mechanism includes an elastic component and a transmission component, the elastic components are arranged in a ring shape at equal intervals inside the shell, the inner upper end of the elastic component is fixedly connected to the outer upper end of the guide tube, the transmission component is fixedly connected to the outer surface lower end of the guide tube at equal intervals, and the outer side of the transmission component is meshingly connected to the external gear.

[0016] Optionally, the elastic component includes an inner groove body, which is opened inside the outer shell at equal intervals, the interior of the inner groove body is fixedly connected to a return spring, the top of the return spring is fixedly connected to a connecting block, and the inner side of the connecting block is connected to the outer side of the guide tube.

[0017] Optionally, the transmission assembly includes a fixed plate and an internal gear, the fixed plates are arranged in a ring shape at equal intervals and fixedly installed on the lower end of the outer surface of the guide tube, the internal gears are rotatably connected to the lower end of the inner part of the strip groove, the internal gear and the external gear are meshingly connected, and a rack is fixedly connected to the outer side of the fixed plate, and the rack and the internal gear are meshingly connected.

[0018] Optionally, the limiting mechanism includes an arc-shaped hole and a mounting frame, the mounting frame is fixedly mounted on one side of the base ring, the arc-shaped hole is opened at the upper end of one side of the outer shell close to the mounting frame, both ends of the interior of the mounting frame are fixedly connected with torsion springs, a turntable is fixedly mounted on the inner end of the torsion spring, the turntable is rotatably connected to the middle part of the mounting frame, the bottom of the turntable is fixedly connected with a limiting rod, and the limiting rod corresponds to the arc-shaped hole.

[0019] Optionally, the arc-shaped hole and the torsion spring are arranged in concentric circles, the side shape of the limiting rod is also arranged in an arc shape, the limiting rod is also arranged in a concentric circle with the torsion spring, and the outer edges and corners of the shell are all arranged in an arc shape.

[0020] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects:

[0021] In the above scheme, by adjusting the base ring to move downward, the guide tube is driven to move downward synchronously, thereby prompting the fixed plate and the rack to move downward as well. Since the rack is tightly meshed with the inner gear, the displacement of the rack smoothly drives the inner gear to rotate, and the inner gear is meshed with the outer gear. Under power transmission, the rotation of the outer gear prompts the correction frame to slowly unfold until its outer covering rubber sheet is flush with the bottom of the outer shell. When the bottom of the outer shell contacts the patient's skin, the outer ends of the correction frame and the covering rubber sheet are precisely fitted to ensure that the entire outer shell and the guide tube are perpendicular to the skin surface. At this time, the injection needle is inserted into the guide tube, and the guide tube plays a guiding role to ensure that the injection needle penetrates the skin vertically, so that stable vertical injection can be achieved, laying a solid foundation for the accurate injection of insulin and improving the injection effect.

[0022] During application, after the injection process is started, the guide tube is driven downward by the base ring, and the limiting mechanism on the base ring is linked accordingly, and the arc-shaped limiting rod at the bottom of the mounting frame moves downward. Once its bottom touches the outer shell, the turntable rotates under the ingenious guidance of the arc surface, and the torsion spring is squeezed and contracted. When the base ring reaches the predetermined appropriate position, the end of the limiting rod docks with the arc-shaped hole, the limit is instantly released, and the torsion spring is quickly reset, pushing the limiting rod inward and accurately inserting it into the arc-shaped hole. The concentric circle structure of the two achieves a perfect fit and mutual limitation, firmly fixing the base ring, allowing the user to easily find the correct position during operation, and the injection process is smoother.

[0023] When the device is in the idle stage, the limit rod automatically shrinks into the strip groove, saving space and avoiding accidental touch. When in use, push the guide tube, the rack drives the inner gear and the outer gear to rotate in coordination, the correction frame quickly unfolds and is ready. After the injection is completed, turn the limit rod to make the turntable drive the limit rod out of the arc hole, pull out the guide tube, and the rack drives in the reverse direction. The correction frame is reset and stored in an orderly manner. The reset spring in the inner groove body is the hero behind the scenes. It is squeezed by the guide tube to accumulate force during injection, and the elastic force is released after the injection is completed, pushing the connecting block to drive the guide tube to reset, and at the same time letting the rack, inner gear and outer gear return to their positions, and the correction frame automatically retracts. The whole process is completed in one go, and the device is easy to unfold and store, which greatly facilitates daily carrying and flexible use. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 1 to 8 As shown, an embodiment of the present invention provides an insulin injection auxiliary device for endocrinology department, including a shell 1, the outer side of the shell 1 is provided with a correction mechanism 2 at equal intervals, the inside of the shell 1 is slidably connected with a guide tube 4, the outer side of the guide tube 4 is fixedly connected with a linkage mechanism 3, the outer side of the linkage mechanism 3 is fixedly connected with the inside of the shell 1, and the guide tube 4 is transmission connected with the correction mechanism 2 through the linkage mechanism 3.

[0048] The correction mechanism 2 includes a strip groove 21, which is arranged in a ring shape at equal intervals and is opened on the outer side of the shell 1. The lower end of the inner part of the strip groove 21 is rotatably connected to an outer gear 22, and the inner side of the outer gear 22 is meshed with the linkage mechanism 3. The top of the outer gear 22 is fixedly connected to a correction frame 23, and the correction frame 23 is accommodated in the inner part of the strip groove 21. During the application of this device, the outer shell 1 is used as the basis, and the correction mechanism 2 arranged at equal intervals on the outer side thereof cooperates with the guide tube 4 and the linkage mechanism 3 that are slidably connected inside to construct a set of precision injection auxiliary system. The strip grooves 21 in the correction mechanism 2 are arranged in a ring shape with equal intervals. Arranged on the outside of the shell 1, it provides a reasonable layout for the operation of subsequent components. The outer gear 22 rotatably connected to the lower end of the strip groove 21 is meshed with the linkage mechanism 3, which can effectively transmit power and accurately drive the correction frame 23 to move. The correction frame 23 is stored in the strip groove 21. When not in use, it saves space and avoids collision damage. When in use, the correction frame 23 can be accurately unfolded according to the transmission of the linkage mechanism 3 and the guide tube 4, and its top can fit closely to the patient's skin, ensuring that the shell 1 and the guide tube 4 are perpendicular to the skin, providing a stable vertical guide for insulin injection, greatly improving the injection accuracy, and ensuring the treatment effect.

[0049] like Figures 1 to 6 As shown, the outer side of the correction frame 23 is fixedly connected with a covering rubber sheet 24, and the covering rubber sheet 24 covers the outer side of the correction frame 23. The outer side of the covering rubber sheet 24 is set in an arc shape.

The arc-shaped design is highly compatible with the contour of human skin, can fit closely to the patient's skin, and effectively fill the possible gap between the correction frame 23 and the skin, further stabilize the state of the outer shell 1 and the guide tube 4 being perpendicular to the skin, and avoid injection deviation caused by poor fit. Moreover, the rubber sheet material is relatively soft, which can not only provide a certain buffer to the patient's skin and reduce discomfort, but also increase the friction with the skin to prevent the correction frame 23 from accidentally moving during the injection process, effectively ensuring the stability and accuracy of insulin injection, and helping to improve the treatment effect.

[0050] like Figures 1 to 5As shown, a base ring 5 is fixedly installed on the outer side of the top of the guide tube 4, a limiting mechanism 6 is provided on one side of the base ring 5, support rods 7 are fixedly installed at equal intervals on the bottom of the base ring 5, and support grooves 8 are opened at equal intervals on the outer side of the shell 1. The bottom of the support rod 7 is inserted into the inside of the support groove 8, and the support rod 7 and the support groove 8 are slidably connected. A guide frame 9 is fixedly connected to the top of the guide tube 4 through the base ring 5, and the side shape of the guide frame 9 is an inverted isosceles trapezoid. The base ring 5 fixed on the outer side of the top of the guide tube 4 is provided with a limiting mechanism 6 on one side, which can accurately control the position of the base ring 5 when the equipment is running, avoid unnecessary displacement, and ensure operational stability. The support rods 7 at equal intervals at the bottom of the base ring 5 are slidably connected to the support grooves 8 at equal intervals on the outside of the shell 1. This structure allows the guide tube 4 to be installed firmly. During the auxiliary insulin injection process, even if there is external interference, the guide tube 4 can maintain a vertical stable state to ensure the accurate injection direction. In addition, the guide frame 9 connected to the base ring 5 at the top of the guide tube 4 has an inverted isosceles trapezoidal setting on its side. In actual use, when the patient is ready to inject, this shape is convenient for guiding the patient to accurately connect the insulin injection instrument to the guide tube 4, thereby improving the convenience of operation, reducing the probability of docking errors, and creating favorable conditions for the smooth injection of insulin.

[0051] like Figures 5 and 6As shown, the linkage mechanism 3 includes an elastic component 31 and a transmission component 32. The elastic components 31 are arranged in a ring shape at equal intervals inside the housing 1. The inner upper end of the elastic component 31 is fixedly connected to the outer upper end of the guide tube 4. The transmission component 32 is fixedly connected to the outer surface lower end of the guide tube 4 at equal intervals. The outer side of the transmission component 32 is meshed with the external gear 22. The elastic component 31 includes an inner groove body 311. The inner groove body 311 is opened inside the housing 1 at equal intervals.

During the use of the equipment, whether it is the initial installation or the subsequent operation, the position of the guide tube 4 can be ensured to be accurate. The transmission component 32 is fixed at equal spacing at the lower end of the outer surface of the guide tube 4 and meshes with the external gear 22 to achieve effective power transmission and accurately drive the correction mechanism 2 to operate. The inner groove 311 in the elastic component 31 is reasonably opened, and the internal The reset spring 312 cooperates with the connecting block 313. During injection, the guide tube 4 squeezes the reset spring 312 to store force. After the injection is completed, the spring resets, driving the guide tube 4 and related components to return to their original positions, thereby realizing automatic adjustment. In the transmission assembly 32, the fixed plate 321 is fixed to the guide tube 4, and the rack 323 thereon is meshed with the rotatably connected internal gear 322, which in turn is meshed with the external gear 22. The layers are tightly linked, allowing the correction frame 23 to be unfolded and stored in an orderly manner, thereby ensuring smooth operation of the equipment and improving the auxiliary effect of insulin injection.

[0052] like Figures 5 to 7As shown, the limiting mechanism 6 includes an arc-shaped hole 61 and a mounting frame 63, the mounting frame 63 is fixedly mounted on one side of the base ring 5, the arc-shaped hole 61 is opened at the upper end of one side of the housing 1 close to the mounting frame 63, both ends of the interior of the mounting frame 63 are fixedly connected with torsion springs 64, the inner end of the torsion spring 64 is fixedly installed with a turntable 65, the turntable 65 is rotatably connected to the middle part of the mounting frame 63, the bottom of the turntable 65 is fixedly connected with a limiting rod 66, the limiting rod 66 corresponds to the arc-shaped hole 61, and the transmission assembly 32 includes a fixing plate 32 1 and the inner gear 322, the fixing plate 321 is arranged in a ring shape with equal spacing and fixedly installed on the lower end of the outer surface of the guide tube 4, the inner gear 322 is rotatably connected to the lower end of the inner part of the strip groove 21, the inner gear 322 and the outer gear 22 are meshed and connected, the outer side of the fixing plate 321 is fixedly connected with a rack 323, the rack 323 and the inner gear 322 are meshed and connected, the arc hole 61 and the torsion spring 64 are arranged concentrically, the side shape of the limiting rod 66 is also arranged in an arc shape, and the limiting rod 66 is also arranged concentrically with the torsion spring 64, The outer corners of the housing 1 are all set to be arc-shaped. The limiting mechanism 6 consists of an arc-shaped hole 61 and a mounting frame 63. The mounting positions of the two are precisely corresponding. The mounting frame 63 is equipped with a torsion spring 64, a turntable 65 and a limit rod 66. The unique concentric circle setting and the arc-shaped side of the limit rod 66, when the equipment is in use, when the base ring 5 drives the guide tube 4 to move downward, the bottom of the limit rod 66 contacts the housing 1. With the help of the arc surface guide, the turntable 65 rotates to squeeze the torsion spring 64. When the base ring 5 reaches the specified position, the torsion spring 64 resets and pushes the limit The rod 66 is inserted into the arc-shaped hole 61, which efficiently assists in fixing the base ring 5, allowing the device to be accurately positioned after adjustment and expansion, providing a stable basis for insulin injection. As for the transmission component 32, the fixing plate 321 is fixed to the lower end of the guide tube 4 in a ring shape, and cooperates well with the inner and outer gears 22 to transmit power in an orderly manner, ensuring that the correction frame 23 moves smoothly and reliably. In addition, the outer edges and corners of the shell 1 are processed into an arc shape, which can effectively prevent collision damage during use, and improve the comfort of holding, and effectively ensure the smooth operation of insulin injection.

[0053] The workflow of the technical solution provided by the present invention is as follows:

[0054] By setting up the correction mechanism 2, during use of the device, the base ring 5 can be first pressed to move downward, and the downward movement of the base ring 5 can drive the guide tube 4 to move downward. At this time, the fixing plate 321 and the rack 323 can be driven downward by the guide tube 4, and the rack 323 and the inner gear 322 are meshed and connected, and then the inner gear 322 can be driven to rotate by the rack 323. During the rotation of the inner gear 322, the inner gear 322 and the outer gear 22 are meshed and connected, and then the outer gear 22 can be driven to rotate by the inner gear 322. By driving the outer gear 22 to rotate, the correction frame 23 can be driven to unfold. At this time, the unfolding of the correction frame 23 can drive the outer covering rubber plate 24 and the bottom of the shell 1. During this period, when the bottom of the shell 1 is attached to the patient's skin, the correction frame 23 can be used to fit the patient's skin, and the outer ends of the coating rubber sheets 24 on the outside of each correction frame 23 can be used to fit the patient's skin, so that the bottom of the shell 1 can be horizontally attached to the patient's skin, and the entire shell 1 and the guide tube 4 inside it can be perpendicular to the patient's skin. At this time, the injection needle can be inserted into the guide tube 4, and the injection can be corrected through the guide tube 4. During the injection, since the guide tube 4 is perpendicular to the patient's skin, the injection needle guided by the guide tube 4 can also be perpendicular to the patient's skin, which can play a stable vertical injection function and ensure the injection effect.

[0055] By setting the linkage mechanism 3, during use, when the device is injected, when the base ring 5 drives the guide tube 4 to move downward, the limiting mechanism 6 on the base ring 5 can be driven to move downward, and the limiting rod 66 at the bottom of the mounting frame 63 moves downward. The side surface of the limiting rod 66 at the bottom of the mounting frame 63 is set in an arc shape. When the bottom of the limiting rod 66 contacts the shell 1, the arc surface of the limiting rod 66 guides and drives the turntable 65 to rotate. The rotation of the turntable 65 can squeeze the torsion spring 64, causing the torsion spring 64 to be in a compressed state. When the base ring 5 drops to a suitable position, The end of the limiting rod 66 contacts with the arc-shaped hole 61. At this time, the limiting rod 66 loses its limit, and the torsion spring 64 loses its limit and can be reset to drive the limiting rod 66 to move inward. The limiting rod 66 moves inward and can be inserted into the inside of the arc-shaped hole 61. The arc-shaped hole 61 and the limiting rod 66 are arranged in concentric circles. The torsion spring 64 is reset to drive the limiting rod 66 to be stably inserted into the inside of the arc-shaped hole 61. The limiting rod 66 and the arc-shaped hole 61 limit each other, and then can assist in clamping and fixing the base ring 5, so that the device can be better positioned after adjustment and expansion, which is convenient for users to perform injection operations.

[0056] By arranging the elastic component 31 and the transmission component 32 to cooperate with each other, during the application of the device, if the device is not in use, the limit rod 66 can be adaptively retracted inside the strip groove 21. During use, the guide tube 4 can be pushed to drive the rack 323 to drive the inner gear 322 to drive the outer gear 22 to rotate so that the correction frame 23 can be unfolded. After the injection is completed, the rotating limit rod 66 is adjusted to drive the turntable 65 to rotate, so that the limit rod 66 can be separated from the arc hole 61. At this time, the limit rod 66 is separated from the arc hole 61, so that the guide tube 4 can be withdrawn. When the guide tube 4 is withdrawn, the rack 323 can drive the inner gear 322 and the outer gear 22 to rotate in the opposite direction, so that the correction frame 23 can be reset and retracted. The guide tube 4 is pressed against the back of the support frame 312, and the guide tube 4 is pressed against the back of the support frame 313, so that the guide tube 4 can be pressed against the back of the support frame 313.
