Description

Technical Field

[0001] This invention relates to the field of adjunctive treatment technology for diabetes, and more specifically to an adjunctive treatment device for diabetes in endocrinology. Background Technology

[0002] Diabetes mellitus is a group of metabolic diseases characterized by chronic hyperglycemia caused by multiple etiologies, resulting from defects in insulin secretion and / or utilization. Long-term disorders of carbohydrate, fat, and protein metabolism can cause multi-system damage, leading to chronic progressive lesions, functional decline, and failure in tissues and organs such as the eyes, kidneys, nerves, heart, and blood vessels. In severe cases or under stress, acute severe metabolic disorders such as diabetic ketoacidosis and hyperosmolar hyperglycemia syndrome can occur. The most effective treatment for diabetic patients is insulin injection.

[0003] The existing technology has the following problems:

[0004] Currently, diabetic patients control their condition directly through insulin injections. However, existing diabetes treatment aids are not conducive to the absorption of injected insulin. In winter, injecting cold insulin may cause discomfort. Furthermore, existing diabetes treatment aids are inconvenient for storing syringes and vials of insulin when patients need to travel, requiring them to search for these items before injection, thus wasting time and causing inconvenience.

[0005] Therefore, we need an endocrinology-specific diabetes treatment aid to solve the above problems. Summary of the Invention

[0006] This invention provides an auxiliary device for the treatment of diabetes in endocrinology, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] An auxiliary device for diabetes treatment in endocrinology includes a housing, two U-shaped frames fixedly connected to the left and right sides of the housing, a storage box fixedly connected to the upper surface of the housing, a lid magnetically fixedly connected to the inside of the storage box, and a handle fixedly connected to the center of the upper surface of the lid.

[0009] The inner rear wall of the outer shell is open to both the inside and outside. A heating plate is slidably connected to the inner rear side of the outer shell. A connecting block is fixedly connected to the left side of the front of the heating plate. Guide rods are slidably connected to the upper and lower right sides of the connecting block. The left and right ends of the upper and lower guide rods are fixedly connected to the inner wall of the outer shell. A pad is fixedly connected to the rear side of the heating plate. Several protrusions are fixedly connected to the rear side of the heating plate in a rectangular array. The outer surfaces of the several protrusions penetrate the interior of the pad.

[0010] A further improvement of the technical solution of the present invention is that: a temperature sensor is fixedly connected to the right side of the front of the heating plate, a battery is fixedly connected to the front right side of the inner wall of the outer shell, and a control module is fixedly connected to the middle of the lower surface of the inner wall of the outer shell.

[0011] A further improvement of the technical solution of the present invention is that: a connecting plate is movably connected to the center of the front of the connecting block, a disk is movably connected to the right side of the connecting plate, a motor is provided in the center of the front of the disk, and the output shaft of the motor is fixedly connected to the center of the surface of the disk.

[0012] A further improvement of the technical solution of the present invention is that: a support plate is fixedly connected to the front right side of the inner wall of the outer shell, the outer surface of the support plate is fixedly connected to the outer surface of the motor, and a charging port is provided on the front right side of the outer shell.

[0013] A further improvement of the technical solution of the present invention is that: a placement plate is fixedly connected inside the storage box, a groove is provided on the left side of the upper surface of the placement plate, and rubber blocks are fixedly connected to the left and right sides of the rear side of the inner wall of the groove, and a slope is provided on the front side of the upper surface of the rubber blocks.

[0014] A further improvement of the technical solution of the present invention is that a placement opening is provided on the right side of the placement plate.

[0015] A further improvement of the technical solution of the present invention is that a fixing bolt is movably connected through the right side of the storage box, and the outer surface of the fixing bolt is threaded through the inside of the clamping block.

[0016] A further improvement of the technical solution of the present invention is that: the outer surface of the clamping block is slidably connected to the inside of the placement port; the heating temperature of the heating plate can be adjusted in stages by the control module, including three stages: 37°C, 38°C, and 39°C; the user can switch between these stages through the operation interface of the control module to adapt to different seasons and the needs of patients with sensitive skin; and the outer surface of the bandage of the U-shaped frame is sewn with multiple length scale lines so that medical staff can quickly adjust the length of the bandage when using it on patients of different body types and ensure that the heating plate is accurately aligned with the injection site.

[0017] A further improvement of the technical solution of the present invention is that: the control module controls the temperature signal T(t) of the heating plate (11) collected by the temperature sensor and the target set temperature T. s Perform real-time comparisons and calculate temperature errors:

[0018] e(t) = T s -T(t)

[0019] The heating power P(t) is dynamically controlled using a proportional-integral-derivative (PID) control algorithm.

[0020]

[0021] Among them, K p K i K d These are the proportional, integral, and derivative coefficients, respectively, thus achieving closed-loop stable control of the heating plate temperature.

[0022] A further improvement of the technical solution of the present invention is that: the control module is preset with an over-temperature protection threshold T. max When the real-time temperature T(t) satisfies:

[0023] T(t)≥T max

[0024] The heating power supply will be automatically cut off, and the alarm module will be triggered to output a prompt signal A(t) = 1 when T(t) <T max When this occurs, the alarm signal is A(t) = 0 to prevent burns to the patient's skin.

[0025] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0026] 1. This invention provides an auxiliary device for diabetes treatment in endocrinology. In use, the U-shaped frame can be fastened and fixed with a bandage, and then the device is worn on the patient's waist. After insulin injection, the motor drives the disc to rotate. Due to the action of the connecting plate, the connecting block and the heating plate move left and right, so that the connecting block slides on the outer surface of the guide rod. At the same time, the heating plate heats up. During the movement of the heating plate, the protrusions massage the area near the injected insulin. This structure facilitates the absorption of injected insulin.

[0027] 2. This invention provides an auxiliary device for diabetes treatment in the endocrinology department. The groove facilitates the placement of the syringe and limits its position after placement. The placement port allows the bottled insulin to be placed inside. The clamping block can be moved by rotating the fixing plug to limit the position of the bottled insulin. This structure enables the storage of the syringe and bottled insulin and facilitates the use of the patient.

[0028] 3. This invention achieves real-time dynamic adjustment of the heating temperature by integrating a temperature sensor and control module onto the heating plate and combining it with a formulaic closed-loop control algorithm. This system can automatically adjust the output power based on individual patient differences and changes in ambient temperature, and can immediately cut off the power and issue an alarm signal when the temperature exceeds a set threshold, effectively preventing skin burns caused by local overheating. Compared with existing auxiliary devices that only use simple constant-power heating, this invention has a higher level of safety and intelligence, making the local heating process after insulin injection more precise, comfortable, and efficient, significantly improving drug absorption and patient experience.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1: As Figures 1 to 4 As shown, the present invention provides an auxiliary device for the treatment of diabetes in the endocrinology department, including a shell 1, a U-shaped frame 2, a storage box 3 and other components.

[0036] The outer shell 1 serves as the main structure of the entire device. Two U-shaped frames 2 are fixedly connected to its left and right sides. These two U-shaped frames 2 can be used to fix the device in a suitable position, for example, by fastening the U-shaped frames 2 with two bandages. The ends of the two bandages are sewn with Velcro hooks and fleece, so that the patient can wear the device at the waist. A storage box 3 is fixedly connected to the upper surface of the outer shell 1. A lid 4 is magnetically fixedly connected to the inside of the storage box 3. A handle is fixedly connected to the middle of the upper surface of the lid 4. The lid 4 can be easily opened or closed by the handle, making it easy to take out and put in the syringes and bottled insulin in the storage box 3.

[0037] The inner rear wall of the outer casing 1 is open to both the inside and outside. A heating plate 11, made of copper, is slidably connected to the inner rear side of the outer casing 1. A connecting block 12 is fixedly connected to the left side of the front of the heating plate 11. Guide rods 13 are slidably connected to the upper and lower right sides of the connecting block 12. The left and right ends of the upper and lower guide rods 13 are fixedly connected to the inner wall of the outer casing 1. The guide rods 13 serve as guides, allowing the heating plate 11 to slide stably left and right within the outer casing 1. This facilitates the movement of the heating plate 11 by subsequent structures, thereby achieving massage for the patient. A pad 1101, made of pure cotton cloth, is fixedly connected to the rear side of the heating plate 11 to prevent the heating plate from... The heating plate 11 comes into direct contact with the patient's skin, providing some protection. A rectangular array of protrusions 1102 are fixedly connected to the rear side of the heating plate 11. The protrusions 1102 facilitate the movement of the heating plate 11 and the protrusions 1102 by subsequent structures, allowing for back-and-forth massage of the injection site. The outer surfaces of the protrusions 1102 penetrate the interior of the pad 1101. When the heating plate 11 is working, the heat it generates can pass through the pad 1101 and contact the patient's skin, providing a suitable temperature to appropriately heat the injection site, promote drug absorption, and reduce patient discomfort.

[0038] A temperature sensor 18 (model DS18B20) is fixedly connected to the right side of the front of the heating plate 11. The temperature sensor 18 can monitor the temperature of the heating plate 11 in real time and transmit the temperature signal to the control module 19 (model CMS32F0301) of the device. The control module 19 can then adjust the heating power of the heating plate 11 according to the set temperature value to ensure that the temperature is stable within a suitable range. A battery 17 is fixedly connected to the front right side of the inner wall of the outer casing 1. The battery 17 provides power support for the entire device, including the heating plate 11, the motor 16, and the control module 19, and they are electrically connected to each other through wires. The control module 19 is fixedly connected to the middle of the lower surface of the inner wall of the outer casing 1.

[0039] Example 2: Figures 1 to 4As shown, a connecting plate 14 is movably connected to the center of the front of the connecting block 12, and a disc 15 is movably connected to the right side of the connecting plate 14. A motor 16 is disposed in the center of the front of the disc 15, and the output shaft of the motor 16 is fixedly connected to the center of the surface of the disc 15. A support plate is fixedly connected to the front right side of the inner wall of the outer casing 1, and the upper surface of the outer surface of the support plate is fixedly connected to the outer surface of the motor 16 to provide stable support for the motor 16. When the motor 16 starts, its output shaft drives the disc 15 to rotate, and the disc 15 drives the connecting block 12 to move through the connecting plate 14, thereby causing the heating plate 11 to slide left and right along the guide rod 13. In this way, the heating plate 11 can move back and forth. A charging port is provided on the front right side of the outer casing 1 to facilitate charging of the battery 17 and ensure normal use of the device.

[0040] Example 3: Figures 1 to 4 As shown, a placement plate 31 is fixedly connected inside the storage box 3. A groove 32 is provided on the left side of the upper surface of the placement plate 31. Rubber blocks 33 are fixedly connected to the left and right sides of the rear side of the inner wall of the groove 32. An inclined surface is provided on the front side of the upper surface of the rubber blocks 33. The groove 32 can be used to place syringes. The setting of the rubber blocks 33 can play a certain limiting role for the syringes placed in the groove 32. The beveled design on the front side of the upper surface of the rubber block 33 facilitates pressing the syringe and the rubber block 33 into the groove 32. The rubber block 33 deforms during pressing. After the syringe is fully inserted into the groove 32, the deformed rubber block 33 returns to its original position and limits the syringe. The right side of the placement plate 31 has a placement opening 34, which can be used to place bottled insulin. The right side of the storage box 3 is movably connected to a fixing bolt 36. The outer surface of the fixing bolt 36 is threaded through the inside of the clamping block 35. The outer surface of the clamping block 35 is slidably connected to the inside of the placement opening 34. By rotating the fixing bolt 36, the clamping block 35 can be moved within the placement opening 34, thereby clamping and fixing the bottled insulin placed in the placement opening 34 to ensure the stability of the item.

[0041] Example 4: In the endocrinology ward of a hospital, after the patient completes an insulin injection, the nurse secures this device to the patient's waist. The main body of the device is the outer shell 1, with U-shaped frames 2 fixedly connected to the left and right sides in a mirror-like manner. The nurse first passes one end of the bandage through the U-shaped frame 2 and uses the hook and loop sides of the Velcro to secure it, so that the back of the outer shell 1 can stably fit against the patient's injection site. A storage box 3 is fixedly connected to the upper surface of the outer shell 1. The inside of the storage box is fixed to the lid 4 by a magnetic structure. The lid 4 has a handle in the middle for easy and quick opening or closing, so as to quickly retrieve or store syringes and vials of insulin during clinical operations.

[0042] A slidingly mounted heating plate 11 is provided on the inner rear wall of the outer casing 1. A connecting block 12 is fixed to the left front side of the heating plate 11, and both ends of the connecting block 12 are slidably connected to the guide rod 13. The two ends of the guide rod 13 are fixed to the inner wall of the outer casing 1, ensuring that the heating plate 11 is controlled and stable when moving left and right. A pad 1101 made of pure cotton cloth is provided on the rear side of the heating plate 11 to prevent direct contact with the skin and burns. At the same time, multiple protrusions 1102 are distributed in a rectangular array on the rear side of the heating plate 1101. The outer surface of these protrusions penetrates the pad 1101 and directly contacts the skin, which can both transfer heat and provide physical massage when the heating plate slides left and right.

[0043] In use, the temperature sensor 18 (model DS18B20) is fixed to the right side of the front of the heating plate 11, collecting the heating plate temperature in real time and transmitting the signal via wire to the control module 19 (model CMS32F0301) installed at the bottom inside the housing 1. The control module adjusts the heating plate power according to the preset temperature (e.g., 38°C). A battery 17 is installed at the front right inside the housing 1 to provide power to the heating plate, motor 16, and control module.

[0044] During operation, the start motor 16 (fixed at the center of the front of the disc 15) drives the disc 15 to rotate via its output shaft. This rotation, through the connecting plate 14, drives the connecting block 12, causing the heating plate 11 to move left and right along the guide rod 13. During this movement, the protrusion 1102 alternately presses on the injection area, accelerating the diffusion of insulin under the skin. Simultaneously, the heat increases local blood flow, effectively improving drug absorption efficiency. The entire heating and massage process is automatically managed by the control module, requiring no manual intervention from the user.

[0045] Example 5: In scenarios where patients travel, the device not only provides heating and massage functions but also features complete portability and storage capabilities. Inside the storage box 3 fixed to the upper surface of the outer shell 1, a groove 32 is formed on the left-side placement plate 31. Rubber blocks 33 are located at both ends of the rear side of the groove, with a sloping structure formed on the front side of the rubber blocks. When placing the syringe, the patient can use the sloping surface to press the rubber block 33. After the rubber block deforms, the syringe slides smoothly into the groove 32, and then the rubber block rebounds, achieving a stable and limited position for the syringe.

[0046] The storage box 3 has a placement opening 34 on the right side plate 31 for placing bottled insulin. A clamping block 35 is slidably connected to the inner wall of the placement opening, and a fixing bolt 36 is threadedly connected to the outer side of the clamping block. After the patient places the insulin bottle into the placement opening 34, rotating the fixing bolt 36 will push the clamping block 35 inward to clamp the bottle and prevent it from shaking or tipping over during transportation.

[0047] During travel, when an injection is needed, the patient opens the box 4 to take out the syringe and insulin for injection. After injection, the U-shaped frame 2 is secured to the waist with a bandage, ensuring the heating plate 11 is directly above the injection area. The device is then activated; the battery 17 powers the motor 16, causing the disc 15 to rotate, which in turn rotates the connecting plate 14 and connecting block 12, allowing the heating plate 11 to reciprocate left and right under the guidance of the guide rod 13. The temperature sensor 18 continuously monitors the temperature and feeds the data back to the control module 19, automatically adjusting the heating power to maintain a constant temperature within the 37–39°C range.

[0048] During this process, the protrusion 1102 repeatedly contacts the skin and moves with the heating plate, forming a combined effect of alternating heat and pressure. This not only improves drug diffusion efficiency but also relieves abdominal discomfort caused by prolonged walking or being outdoors. After use, the syringe and insulin are returned to the storage box 3, and the lid 4 is magnetically closed to ensure the safety, hygiene, and portability of the device.

[0049] In this embodiment, the implementation process of the temperature control system is described in detail.

[0050] After the patient completes insulin injection, the caregiver secures the device to the patient's waist using a U-shaped frame 2 and a bandage, ensuring the rear side of the heating plate 11 is in contact with the injection area. Upon activation, the temperature sensor 18 begins to collect the temperature signal of the heating plate 11 in real time, denoted as T(t). The control module 19 has a preset target temperature T. s For example, 38℃. Control module 19 first calculates the error between the real-time temperature and the target temperature:

[0051] e(t) = T s -T(t)

[0052] Where e(t) is the temperature deviation.

[0053] To achieve stable temperature control of the heating plate, control module 19 runs a PID control algorithm to calculate the heating power P(t) based on the error e(t):

[0054]

[0055] Among them, K p K i K d These are the proportional, integral, and derivative coefficients, respectively. Using this algorithm, the device can rapidly heat up when the temperature drops and promptly reduce power when the temperature rises too quickly, achieving closed-loop control and ensuring that the temperature of the heating plate 11 remains stable near the target set value. To further ensure safety, the control module 19 in this embodiment also presets an over-temperature protection threshold T. max For example, 40℃. When temperature sensor 18 detects:

[0056] T(t)≥T max

[0057] Control module 19 immediately cuts off the heating power supply and triggers the alarm module to output a prompt signal A(t) = 1. At this time, the buzzer sounds or the indicator light flashes to alert the patient or caregiver. If the temperature returns to the safe range, i.e., T(t)... <T max When the alarm signal changes to A(t) = 0, the device can re-enter normal operating mode. Throughout the process, the protrusion 1102 physically massages the injection site as the heating plate 11 moves back and forth, while a stable temperature control system provides constant temperature heating, which accelerates the diffusion and absorption of insulin and avoids the risk of skin discomfort or burns caused by excessive temperature fluctuations.

[0058] Working principle: During use, the user can wear the device on the patient's waist through the installation of the bandage, so that the back of the heating plate 11 comes into contact with the injected insulin. The heating plate 11 heats the area, and then the motor 16 is started. The motor 16 drives the disc 15 to rotate, and the heating plate 11 moves left and right through the connecting plate 14 and the connecting block 12. During the movement, the protrusion 1102 massages the injected site from left to right, which accelerates the absorption of insulin.

[0059] Before use, the device can be taken out of the backpack, the lid 4 of the storage box 3 can be opened, and the syringe and bottle of insulin can be taken out from the groove 32 and the placement opening 34 of the placement plate 31, making it convenient for patients to use for injection. When a bottle of insulin is used up, it can be taken out and then a new bottle of insulin can be placed in place for the next use.

[0060] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
