Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an abdominal injection positioning device for diabetic patients based on insulin therapy. Background Art

[0002] For patients who cannot produce enough insulin or have insulin resistance, since the pancreatic beta cells are destroyed by the immune system and cannot produce enough insulin, they need to rely on exogenous insulin for life. Treatment generally adopts multiple subcutaneous injections (MDI) or continuous subcutaneous insulin infusion (CSII, i.e. insulin pump) to administer drugs. Diabetic patients use the vertical injection method to inject insulin, especially when using a short needle (such as 4 mm or shorter). Vertical injection ensures that the insulin is properly delivered to the subcutaneous fat layer instead of the muscle layer, which is very important for the absorption and effect of the drug.

[0003] The abdominal injection assist devices currently on the market, such as abdominal bandages, positioning hole pads and warming pads, can assist injection positioning and provide warmth to a certain extent, but they are limited to basic functions and fail to effectively assist patients in maintaining the vertical angle required for injection, which poses a challenge to the rapid and effective absorption of drugs. For example, the patent with a publication number of CN213609025U and a publication date of July 6, 2021, discloses an insulin injection positioning belt, which realizes positioning disinfection and injection functions through the cooperation of the first positioning hole and the second positioning hole; at the same time, with the help of the first belt body, the second belt body, the switch button and the heating wire, the user is provided with heating and warmth. However, the common limitations of such devices are: It only relies on positioning holes to assist users in positioning, disinfection and injection. It lacks angle assistance and is not equipped with functions to help patients maintain the correct injection angle. This may require patients to receive additional training or seek other auxiliary means to ensure that each injection is performed at the appropriate angle. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment: A device for positioning abdominal injections for diabetic patients based on insulin therapy, such as Figure 1-Figure 14As shown, it includes a positioning frame 1, a front cover 11, a back cover 12, a belt 13, a magnetic buckle 14, a ratchet ring 2, a rotating shaft 21, a small claw tooth 22, a torsion spring 23, a connecting plate 24, a twisting frame 25, a limiting cylinder 26, a spring I 27, a twisting member 3, a matching member 31 and a spring II 32. The front cover 11 is clamped in the positioning frame 1, and the back cover 12 is clamped in the rear side of the positioning frame 1. When the device needs to be cleaned, the front cover 11 and the back cover 12 can be pulled outward from both sides of the positioning frame 1, and can be re-inserted into the positioning frame 1 after cleaning. Six symmetrical injection ports 121 are opened in the center of the back cover 12. The belts 13 are symmetrically arranged on both sides of the positioning frame 1 by glue. The belts 13 are made of high elastic material. The back cover 12 is made of a material, and the rear ends of the waist belts 13 on both sides are provided with magnetic buckles 14 by means of glue. The magnetic buckles 14 on both sides cooperate magnetically. A ratchet ring 2 is rotatably provided on the front side of the back cover 12. A rotating shaft 21 is provided on the left and right sides of the front side of the back cover 12. The rotating shafts 21 on both sides are adjacent to the two sides of the ratchet ring 2. Small claw teeth 22 are rotatably provided on the rotating shafts 21 on both sides. The small claw teeth 22 are rotatably engaged with the ratchet ring 2. The small claw teeth 22 on the right side are set forward, and the small claw teeth 22 on the left side are set reversely, and the small claw teeth 22 on both sides are against the ring teeth of the ratchet ring 2. A torsion spring 23 is provided between the small claw teeth 22 and the rotating shaft 21. The torsion spring 23 can provide a torque for the small claw teeth 22 to assist in rotation. A connecting disk 2 is fixedly provided on the front side of the ratchet ring 2 4. A twisting frame 25 is fixedly arranged on the front side of the connecting disk 24. The front part of the twisting frame 25 protrudes from the outside of the middle part of the front cover 11. The protruding part is a manual rotating part. An opening parallel to the injection port 121 is opened on the right side of the twisting frame 25. A vertically arranged limiting cylinder 26 is slidably connected to the top of the connecting disk 24. The vertical structure of the limiting cylinder 26 can ensure that the insulin syringe can be accurately positioned. A through hole corresponding to the size of the injection port 121 is opened on one side of the connecting disk 24, and the rear end of the limiting cylinder 26 is adapted to the through hole. The front end of the limiting cylinder 26 is close to the inner rear side of the twisting frame 25, and the rear end of the limiting cylinder 26 extends into the injection port 121 of the rear cover 12. A setting is arranged between the limiting cylinder 26 and the connecting disk 24. There is a spring I27, which can drive the limit cylinder 26 that has slid down to reset and slide when it is in the reset and extended state. A torsion piece 3 is arranged in the middle part of the rear cover 12, and a matching piece 31 is arranged to rotate and slide at the rear of the connecting plate 24. The torsion piece 3 and the matching piece 31 rotate and cooperate, and a spring II32 is arranged between the torsion piece 3 and the matching piece 31. The torsion piece 3 and the matching piece 31 are matched at one end thereof, and the ends of the torsion piece 3 and the matching piece 31 are both wavy, and the wavy parts are evenly spaced circumferentially along the ends of the two, and there are six spacing distances in total, and the six spacing distances are consistent with the number of injection ports 121, so that when the torsion piece 3 and the matching piece 31 rotate, they can assist in positioning the insulin syringe.

[0036] When the device is used to perform abdominal injection on a diabetic patient, the waist belt 13 on both sides of the device is firstly wrapped around the abdomen, and the magnetic buckles 14 at both ends of the waist belt 13 are naturally adsorbed and docked, and the device is securely fixed to the center of the patient's abdomen, ensuring that after wearing, the positioning frame 1 will be located in the center of the abdomen, and the middle of the back cover 12 is accurately aligned with the area near the patient's navel. Before injection, align the insulin syringe with the opening on the twisting frame 25, insert it smoothly, and push it along the vertical channel of the limiting cylinder 26. The vertical structure of the limiting cylinder 26 ensures that the syringe can be accurately positioned and slide smoothly along its axis. When the insulin needle approaches the bottom of the limiting cylinder 26, the syringe is tightly attached to the cylinder wall. The needle 26 will slide into the inner part of the connecting plate 24 and pass through the injection port 121 at the rear. At this time, the bottom of the limiting cylinder 26 will compress the spring I 27, causing it to deform and shorten. As the syringe is further advanced, the insulin needle will completely pass through the bottom of the limiting cylinder 26 and directly reach the patient's skin through the injection port 121, ensuring that the needle tube accurately enters the subcutaneous layer of the abdomen. Once the needle tube is fully in place, just press the injection pump, and the insulin solution can be smoothly injected into the subcutaneous fat layer, successfully completing the vertical injection of the abdomen. The whole process is easy to operate, and there is no need to manually correct the vertical angle of the syringe, which greatly facilitates the use of patients or caregivers. To ensure the interval between each abdominal injection position, the patient needs to gently lift the insulin syringe after completing the injection, and use the restoring force of spring I 27 to safely remove the syringe from the limiting cylinder 26. At this time, spring I 27 is naturally reset, and the limiting cylinder 26 also returns to the initial position. In order to change the position of the next injection, slightly turn the twisting frame 25 to drive the connecting disk 24 and the ratchet ring 2 to rotate synchronously. The rotation of the ratchet ring 2 causes the small claw teeth 22 on both sides to alternately engage with the ring teeth on the ratchet ring 2. In this process, the small claw teeth 22 interact with the ratchet ring 2 through the rotating shaft 21, so that the torsion spring 23 is periodically tightened and relaxed. The positively rotating small claw teeth 22 push the ring teeth of the ratchet ring 2 upward, while the reversely rotating small claw teeth 22 push the ring teeth of the ratchet ring 2 upward. The small claw 22 is pushed downward to ensure that the rotation process is smooth and uniform. When the connecting disk 24 rotates, its front end component rotates synchronously, and the matching piece 31 at the rear end also rotates, forming a rotational contact with the torsion piece 3 at the front end of the rear cover 12. The matching piece 31 and the wavy part at the end of the torsion piece 3 are staggered during rotation to form a gap. With the help of the elastic force of the spring II 32, the matching piece 31 is lifted up, and the two maintain an alternating fit and staggered state during the rotation process. When the opening of the torsion frame 25 is aligned with the new injection position, the rotation stops. At this time, the matching piece 31 and the torsion piece 3 are in a stable fit state, ensuring that the limit cylinder 26 is accurately aligned with the injection port 121 on the rear cover 12, providing precise positioning for the next injection.

[0037] like Figure 12-Figure 15As shown, it also includes a clamping piece 4, a spring III 41, a collar 42, a connecting rod 43, a limit frame 44, a guide plate I 441, a guide plate II 442 and a fixed plate 45. The clamping pieces 4 are slidably arranged on both sides of the left and right sides of the lower inner part of the limit cylinder 26. The left and right ends of the clamping pieces 4 on both sides penetrate the left and right sides of the lower inner part of the limit cylinder 26. Springs III 41 are arranged between the clamping pieces 4 on both sides and the inner lower parts of both sides of the limit cylinder 26. When the spring III 41 is in the restored extended state, it will drive the clamping piece 4 to slide. The clamping pieces 4 on both sides penetrate the left and right sides of the lower inner part of the limit cylinder 26 and are slidably arranged on both ends of the left and right sides. The collars 42 and the end of the clamping piece 4 will not slide out excessively, a vertical connecting rod 43 is provided at the bottom of each ring 42, and a limit frame 44 is symmetrically slidably provided on the upper and lower sides of the right front end of the connecting disk 24, and the front ends of the limit frames 44 on both sides are against the rear ends of the limit tubes 26, and guide plates I 441 are symmetrically provided on both sides of the limit frames 44, and the rear ends of the connecting rods 43 are slidably connected to the guide plates I 441, and guide plates II 442 are provided on the sides of the limit frames 44 away from each other, and fixed plates 45 are provided on the sides of the guide plates II 442 away from each other, and the rear ends of the guide plates II 442 are slidably connected to the front ends of the fixed plates 45.

[0038] When the insulin syringe is inserted into the limiting cylinder 26 and pushed to the rear end, the edge of its needle first touches the elastic clamping piece 4 on the inner side of the lower part of the limiting cylinder 26, forcing the clamping piece 4 to open outward. This action triggers the compression deformation of the spring III 41 between the clamping piece 4 and the limiting cylinder 26, and then the spring quickly returns to its original state to ensure that the needle is firmly clamped. At the same time, the two ends of the clamping piece 4 slide along the guide track, driving the end ring 42 and the connected connecting rod 43 to move synchronously. The movement of the connecting rod 43 acts on the guide plate I 441, thereby prompting the limiting frame 44 to slide laterally on the fixed plate 45 through the guide plate II 442. The sliding of the limiting frame 44 releases the constraint on the limiting cylinder 26, laying the foundation for subsequent operations. As the insulin syringe is further pushed forward, the user lightly presses the end of the syringe to guide the needle to penetrate the opening on the connecting disk 24, and continue to penetrate until it passes through the injection port 121, while pushing the limiting cylinder 26 backward to ensure that the insulin needle tube accurately enters the patient's abdomen. At this point, the syringe is in place and insulin injection can be performed safely.

[0039] like Figure 1-Figure 7 and Fig.11 As shown, it also includes an electric heating element 5 and a heat-conducting wire 51. The electric heating element 5 is arranged on the front side of the front cover 11. An insulating layer is provided between the connection between the front cover 11 and the electric heating element 5 to prevent current leakage. The rear part of the electric heating element 5 is located in the positioning frame 1, and the positioning frame 1 covers and protects the rear part. The heat-conducting wire 51 is arranged on the lower end of the electric heating element 5. The heat-conducting wire 51 is a carbon fiber heating wire with high heat conversion efficiency and good temperature control characteristics. An embedding groove 52 is opened on the front side of the rear cover 12, and the heat-conducting wire 51 is located in the embedding groove 52.

[0040] Before wearing the device, start the electric heating element 5 in advance. The electric heating element 5 will quickly heat the thermal wire 51, so that the entire back cover 12 reaches a warm temperature suitable for human contact. After preheating, wear the device on the abdomen. At this time, the warmth emitted by the back cover 12 will be directly transferred to the skin, providing a continuous warming effect for the abdomen, so that in cold weather, the abdomen can be effectively prevented from getting cold during the injection process, ensuring that the patient feels comfortable and safe during the injection.

[0041] like Figure 1-Figure 4 and Figure 9-10 As shown, it also includes an electric guide frame 6, a liquid storage bottle 61, an infusion tube 62, a telescopic hose 63, a wiping block 64 and a plugging cover 65. The electric guide frame 6 is set on the rear part of the rear cover 12 by screws. The liquid storage bottle 61 is set on the right side of the positioning frame 1. The liquid storage bottle 61 is made of transparent plastic material. The bottom end of the liquid storage bottle 61 is set with an infusion tube 62. The end of the infusion tube 62 runs through the right side of the electric guide frame 6 and extends into the interior thereof. The end of the infusion tube 62 is set with a telescopic hose 63, which is made of rubber material. The end of the telescopic hose 63 is set with a wiping block 64. The wiping block 64 is slidably connected between the upper and lower sides inside the electric guide frame 6. The rear end of the wiping block 64 can be pulled out and replaced, and the rear end of the wiping block 64 is made of a soft sponge material with strong adsorption properties, which can absorb liquid to prevent leakage. A plugging cover 65 is hinged on the top of the liquid storage bottle 61, and the lower end of the plugging cover 65 is inserted into the top of the liquid storage bottle 61. The plugging cover 65 is the main closing component of the liquid storage bottle 61 to prevent dust or other objects from falling into it and affecting the sterile state of the inside of the liquid storage bottle 61. When it is necessary to install liquid in the liquid storage bottle 61, the lower end of the plugging cover 65 can be pulled out from the liquid storage bottle 61.

[0042] Before preparing abdominal injection, first unscrew plugging cap 65, add appropriate amount of iodine tincture disinfectant in liquid storage bottle 61.After finishing, tighten plugging cap 65 again, guarantee liquid storage bottle 61 sealing, avoid iodine tincture disinfectant from contacting with external air, prevent bacteria from breeding.The iodine tincture disinfectant of filling will naturally settle to liquid storage bottle 61 bottoms, flow into telescopic hose 63 by infusion tube 62, finally absorbed by wiping block 64, guarantee that it fully soaks, after wearing this device, start electric guide frame 6, drive wiping block 64 to carry out two-way sliding along setting path, in this process, the telescopic hose 63 initially in compressed state stretches with the movement of wiping block 64, continue to supply disinfectant to wiping block 64, wiping block 64 sliding on abdominal surface has realized large-scale effective disinfection, creates conditions for the injection operation to be carried out, improves the safety of injection.

[0043] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
