An insulin injection assistance device for the endocrinology department

Abstract

The present invention provides an insulin injection assistance device for the endocrinology department, belonging to the technical field of insulin injection assistance. It includes a housing, and correction mechanisms are equidistantly arranged on the outer side of the housing. In the present invention, by adjusting the downward movement of the adjustment base ring, the guiding tube can be driven to move downward synchronously, prompting the fixed plate and the rack to also move downward. Since the rack is tightly meshed with the internal gear, the displacement of the rack smoothly drives the internal gear to rotate, and the internal gear meshes with the external gear. Under the power transmission, the rotation of the external gear causes the correction frame to slowly unfold until the rubber plate on its outer side is flush with the bottom of the housing. When the bottom of the housing contacts the patient's skin, the outer ends of the correction frame and the rubber plate fit precisely, ensuring that the entire housing and the guiding tube are perpendicular to the skin surface. At this time, the injection needle is inserted into the guiding tube, and the guiding tube plays a guiding role to ensure that the injection needle vertically pierces the skin, realizing a stable vertical injection.

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 the endocrinology department. Background Art

[0002] Diabetes, as a common disease with a relatively high incidence in the population, poses a severe challenge to the physical health of the general public. If suffering from diabetes for a long time, the continuous hyperglycemic state in the body will gradually cause chronic damage to various tissues, affecting key parts such as the eyes, kidneys, heart, blood vessels, and nerves, and then leading to dysfunction, seriously affecting the quality of life and even the life and health of patients. In the clinical treatment field 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 an insulin pen to precisely adjust the required injection dose. After strictly disinfecting the skin, they select an appropriate angle to inject insulin subcutaneously and need to stay for at least 10 seconds before pulling out the needle. Each link in this series of operation processes, especially the precise control of the injection angle and the standardization of the operation, is closely related to the final effect that insulin treatment can achieve and directly determines the effectiveness of blood sugar control.

[0003] However, according to the professional guidance of the "China Diabetes Drug Injection Technology Guide 2021 Edition", when adult patients use relatively short needles such as 4mm, 5mm, and 6mm for injection, the standard operation should be to insert the needle perpendicular to the skin surface at 90° to ensure that the drug can be accurately delivered to the appropriate tissue layer under the skin and achieve the best drug absorption and treatment effect. Focusing on the actual scenario of daily insulin injection 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 problems when performing this key process of insulin injection.

[0004] Some patients, due to physical discomfort and lack of injection operation experience, simply rely on their own perception to determine the appropriate injection site on the skin surface, with poor accuracy and easy to have positioning deviation. They usually do not accurately insert the needle perpendicular to the skin at 90°, often wrongly inject insulin into the muscle layer or deviate from the ideal site of the subcutaneous tissue, which seriously hinders the normal absorption of the drug and causes insulin to fail to fully exert its hypoglycemic effect.

[0005] At the same time, during the injection preparation stage, due to factors such as nervousness and physical weakness, the patient's hand often trembles uncontrollably, making it difficult to accurately reach the standard 90° perpendicular state of the injection angle. At the same time, it is also difficult for medical staff to ensure a 90° perpendicular state injection every time when directly using a syringe for injection. It can be seen that it is easy to cause a series of non-standard operation problems, including completely wrong injection sites, leakage of liquid at the injection site of the skin, and the situation where it should be injected subcutaneously but becomes intradermal injection.

[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:

[0009] An insulin injection auxiliary device for endocrinology department, comprising a shell, a correction mechanism is arranged at equal intervals on the outer side of the shell, a guide tube is slidably connected to the inside of the shell, a linkage mechanism is fixedly connected to the outer side of the guide tube, the outer side of the linkage mechanism is fixedly connected to the inner side of the shell, and the guide tube is transmission-connected to the correction mechanism through the linkage mechanism;

[0010] The correction mechanism includes a strip groove, which is arranged in a ring shape at equal intervals and opened on the outer side of the shell. 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 an equidistant annular pattern inside the outer shell. The upper end of the inner side of the elastic component is fixedly connected to the upper end of the outer side of the guiding tube. The transmission components are fixedly connected to the lower end of the outer surface of the guiding tube at equal intervals. The outer side of the transmission component is meshed and connected with the external gear.

[0016] Optionally, the elastic component includes an inner groove body. The inner groove bodies are opened in the outer shell at equal intervals. A return spring is fixedly connected inside the inner groove body. The top of the return spring is fixedly connected with a connecting block. The inner side of the connecting block is connected to the outer side of the guiding tube.

[0017] Optionally, the transmission component includes a fixing plate and an internal gear. The fixing plates are fixedly installed on the lower end of the outer surface of the guiding tube in an equidistant annular pattern. The internal gears are all rotatably connected to the lower end inside the strip-shaped groove. The internal gear is meshed and connected with the external gear. A rack is fixedly connected to the outer side of the fixing plate. The rack is meshed and connected with the internal gear.

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

[0019] Optionally, the arc-shaped hole and the torsion spring are concentrically arranged. The side shape of the limiting rod is also arc-shaped. The limiting rod is also concentrically arranged with the torsion spring. The external corners of the outer shell are all arranged in an arc shape.

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

[0021] In the above solution, by adjusting the downward movement of the base ring, the guiding tube is driven to move downward synchronously, and then the fixing plate and the rack also move downward. Since the rack is tightly meshed with the internal gear, the displacement of the rack smoothly drives the internal gear to rotate. The internal gear is engaged with the external gear. Under the power transmission, the external gear rotates to cause the correction frame to slowly unfold until the rubber plate on its outer side 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 rubber plate are precisely fitted, ensuring that the entire outer shell and the guiding tube are perpendicular to the skin surface. At this time, the injection needle is inserted into the guiding tube, and the guiding tube plays a guiding role to ensure that the injection needle vertically pierces the skin, and stable vertical injection is realized, laying a solid foundation for the precise 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-shaped groove 21. The strip-shaped grooves 21 are arranged in a ring at equal intervals on the outer side of the housing 1. The lower end inside the strip-shaped groove 21 is rotatably connected to an external gear 22. The inner side of the external gear 22 is meshed and connected to the linkage mechanism 3. The top of the external gear 22 is fixedly connected to a correction frame 23. The correction frame 23 is received inside the strip-shaped groove 21. During the application of this device, based on the housing 1, the correction mechanisms 2 arranged at equal intervals on its outer side, in cooperation with the guiding tube 4 slidably connected inside and the linkage mechanism 3, construct a precise injection assistance system. The strip-shaped grooves 21 in the correction mechanism 2 are arranged in a ring at equal intervals on the outer side of the housing 1, providing a reasonable layout for the operation of subsequent components. The external gear 22 rotatably connected to the lower end inside the strip-shaped groove 21 is meshed with the linkage mechanism 3, which can effectively transmit power and accurately drive the correction frame 23 to act. The correction frame 23 is received inside the strip-shaped groove 21. In the non-use state, it saves space and avoids situations such as collision damage. When in use, the correction frame 23 can be precisely unfolded according to the transmission of the linkage mechanism 3 and the guiding tube 4, and its top can closely fit the patient's skin, ensuring that the housing 1 and the guiding tube 4 are perpendicular to the skin, providing a stable vertical guide for insulin injection, greatly improving the injection accuracy, and guaranteeing the treatment effect.

[0049] As Figures 1 to 6 shown, an outer covering rubber plate 24 is fixedly connected to the outer side of the correction frame 23. The outer covering rubber plate 24 covers the outer side of the correction frame 23. The outer side of the outer covering rubber plate 24 is arranged in an arc shape. When in use, when the correction frame 23 is unfolded according to the transmission of the linkage mechanism 3 and the guiding tube 4, the outer covering rubber plate 24 can be accurately positioned accordingly. Its arc-shaped design has a high degree of fit with the contour of the human skin, can closely fit the patient's skin, effectively fill the possible gaps between the correction frame 23 and the skin, further stabilize the state of the housing 1 and the guiding tube 4 being perpendicular to the skin, and avoid injection deviation caused by poor fitting. Moreover, the rubber plate material is relatively soft, which can not only give a certain buffer to the patient's skin, reduce discomfort, but also increase the friction with the skin, prevent the correction frame 23 from accidentally shifting during the injection process, and effectively guarantee the stability and accuracy of insulin injection, helping to improve the treatment effect.

[0050] As Figures 1 to 5As shown, a base ring 5 is fixedly installed on the outer side of the top of the guiding tube 4. A limiting mechanism 6 is arranged on one side of the base ring 5. The bottom of the base ring 5 is fixedly installed with support rods 7 at equal intervals. Support fixing grooves 8 are arranged on the outer side of the housing 1 at equal intervals. The bottom of the support rod 7 is inserted into the interior of the support fixing groove 8, and the support rod 7 is slidably connected to the support fixing groove 8. The top of the guiding tube 4 penetrates through the base ring 5 and is fixedly connected to a guiding frame 9. The side shape of the guiding frame 9 is arranged in an inverted isosceles trapezoid. The base ring 5 fixedly installed on the outer side of the top of the guiding tube 4 has a limiting mechanism 6 on one side, which can accurately control the position of the base ring 5 during the operation of the device, avoid unnecessary displacement, and ensure the stability of the operation. The support rods 7 at equal intervals at the bottom of the base ring 5 are slidably connected to the support fixing grooves 8 arranged on the outer side of the housing 1 at equal intervals. This structure makes the installation of the guiding tube 4 stable. During the insulin injection assistance process, even if there is external interference, the guiding tube 4 can maintain a vertical and stable state, ensuring the accuracy of the injection direction. In addition, the guiding frame 9 connected to the top of the guiding tube 4 through the base ring 5 has an inverted isosceles trapezoid on its side. In actual use, when the patient is ready to inject, this shape facilitates guiding the patient to accurately dock the insulin injection device to the guiding tube 4, improves the operation convenience, reduces the probability of docking errors, and creates favorable conditions for the smooth injection of insulin.

[0051] As Figures 5 to 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 at equal intervals inside the housing 1. The upper inner side of the elastic component 31 is fixedly connected to the upper outer side of the guide tube 4. The transmission components 32 are fixedly connected to the lower outer surface 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 bodies 311 are opened in the housing 1 at equal intervals. A return spring 312 is fixedly connected inside the inner groove body 311. The top of the return spring 312 is fixedly connected to a connection block 313. The inner side of the connection block 313 is connected to the outer side of the guide tube 4. The transmission component 32 includes a fixing plate 321 and an internal gear 322. The fixing plates 321 are fixedly installed in a ring at equal intervals on the lower outer surface of the guide tube 4. The internal gears 322 are all rotatably connected to the lower end inside the strip-shaped groove 21. The internal gears 322 are meshed with the external gear 22. The outer side of the fixing plate 321 is fixedly connected with a rack 323. The rack 323 is meshed with the internal gear 322. The elastic components 31 are arranged in a ring at equal intervals inside the housing 1, and its upper inner side is fixed to the upper outer side of the guide tube 4, which can provide a stable supporting force for the guide tube 4. During the use of the device, whether it is the initial installation or subsequent operations, the position of the guide tube 4 can be ensured to be accurate. The transmission components 32 are fixedly arranged at equal intervals on the lower outer surface of the guide tube 4 and are meshed with the external gear 22 to achieve effective power transmission and accurately drive the correction mechanism 2 to operate. The inner groove body 311 in the elastic component 31 is reasonably opened, and the internal return spring 312 cooperates with the connection block 313. During injection, the guide tube 4 squeezes the return spring 312 to store energy, and after the injection is completed, the spring resets, driving the guide tube 4 and related components to return to their positions, realizing automatic adjustment. In the transmission component 32, the fixing plate 321 is fixed to the guide tube 4, and the rack 323 thereon is meshed with the rotatably connected internal gear 322, and the internal gear 322 is also meshed with the external gear 22, with close layer-by-layer linkage, enabling the correction frame 23 to be unfolded and stored in an orderly manner, ensuring the smooth operation of the device and improving the auxiliary effect of insulin injection.

[0052] As 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 the use of this device, first, the base ring 5 can be pressed downwards, and when the base ring 5 moves downwards, it can drive the guide tube 4 to move downwards. At this time, the fixed plate 321 and the rack 323 can be driven to move downwards through the guide tube 4. The rack 323 is meshed and connected with the internal gear 322. Furthermore, the internal gear 322 can be driven to rotate through the rack 323. During the rotation of the internal gear 322, the internal gear 322 is meshed and connected with the external gear 22. Furthermore, the external gear 22 can be driven to rotate through the internal gear 322. By driving the external gear 22 to rotate, the correction frame 23 can be driven to unfold. At this time, when the correction frame 23 unfolds, it can drive the coating rubber plate 24 on its outer side to be flush with the bottom of the outer shell 1. During this period, when the bottom of the outer shell 1 fits onto the patient's skin, the correction frame 23 can fit onto the patient's skin. By the outer ends of the coating rubber plates 24 on the outer sides of each correction frame 23 fitting onto the patient's skin, the bottom of the outer shell 1 can be made to fit horizontally onto the patient's skin, causing the entire outer shell 1 and the guide tube 4 inside it to be perpendicular to the patient's skin. At this time, the injection needle can be inserted into the inside of the guide tube 4, and at this time, 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 will also be perpendicular to the patient's skin, being able to achieve a stable vertical injection function and ensure the injection effect.

[0055] By setting up the linkage mechanism 3, during the use of this device, when the device is injecting and the base ring 5 drives the guide tube 4 to move downwards, the limiting mechanism 6 on the base ring 5 can be driven to move downwards at this time. At this time, the limiting rod 66 at the bottom of the mounting frame 63 moves downwards. The side shape of the limiting rod 66 at the bottom of the mounting frame 63 is arc-shaped. When the bottom of the limiting rod 66 contacts the outer shell 1, the arc surface of the limiting rod 66 guides and can drive the turntable 65 to rotate. The turntable 65 rotates and 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 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 reset to drive the limiting rod 66 to move inwards. The limiting rod 66 moves inwards and can be inserted into the inside of the arc-shaped hole 61. The arc-shaped hole 61 and the limiting rod 66 are concentrically arranged. The torsion spring 64 resets and can drive the limiting rod 66 to be stably inserted into the inner side of the arc-shaped hole 61. The limiting rod 66 and the arc-shaped hole 61 are mutually limited. Furthermore, the base ring 5 can be assisted in being clamped and fixed, enabling the device to be better positioned after adjustment and unfolding, facilitating the user's injection operation.

[0056] By setting the elastic component 31 and the transmission component 32 to cooperate, during the application of this device, when the device is not in use, its limiting rod 66 can adaptively contract inside the strip-shaped groove 21. During the use process, the correction frame 23 can be unfolded by pushing the guiding tube 4 to drive the rack 323 to drive the internal gear 322 to drive the external gear 22 to rotate. After the injection is completed, by adjusting the rotation of the limiting rod 66 to drive the turntable 65 to rotate, the limiting rod 66 can then be disengaged from the arc-shaped hole 61. At this time, the limiting rod 66 is disengaged from the arc-shaped hole 61, and then the guiding tube 4 can be retracted. When retracting the guiding tube 4, the rack 323 can drive the internal gear 322 and the external gear 22 to rotate in the reverse direction, and then the correction frame 23 can be reset and stored inside the strip-shaped groove 21. During the use process, since the reset spring 312 is installed inside the inner groove body 311, the reset spring 312 can be compressed by the extrusion of the guiding tube 4 during use. After the guiding and auxiliary injection is completed, the reset of the reset spring 312 can push the connecting block 313 to slide upward inside the inner groove body 311, and then the guiding tube 4 can be driven to reset. The reset of the guiding tube 4 can synchronously drive the rack 323, the internal gear 322, and the external gear 22 to reset, so that the correction frame 23 can be automatically stored inside the strip-shaped groove 21. It can be seen that the overall auxiliary operation of this device is relatively convenient during deployment, and the correction frame 23 can automatically retract after the auxiliary injection is completed, which is convenient for flexible use and carrying.

[0057] This invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of this invention.
