Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically a needle-free injection pressure electronic training device. Background Technology

[0002] Insulin injection is a commonly used method in the treatment of diabetes. Its mechanism of action is to regulate blood sugar levels by directly injecting insulin into the body. For most diabetic patients, once conventional oral hypoglycemic drugs cannot effectively control blood sugar, doctors usually recommend insulin injection to help control the patient's blood sugar levels.

[0003] However, insulin injection methods are mainly divided into two types: needle injection and needle-free injection. Needle injection, as the name suggests, uses a traditional syringe to inject insulin into the patient's subcutaneous tissue through a needle. Although this method has a long history, it may cause some pain and discomfort to the patient. In contrast, needle-free injection is a newer technology that uses high-pressure jet to allow insulin to penetrate the skin and enter the body, thereby avoiding the use of needles and reducing the patient's pain and fear.

[0004] Current products are made solely of silicone, which, as a form of simulated skin, has certain limitations and cannot fully meet the training needs of needle-free injection products. Specifically, due to the material density limitations of ordinary silicone simulated skin, it is significantly insufficient in simulating the pressure feedback and injection resistance of real human tissue. This makes it difficult for users to obtain a realistic tactile sensation similar to actual injection during training. At the same time, quantifying the correct injection force also becomes difficult. Therefore, in actual operation, the injection force may be too large or too small due to individual differences, increasing the safety risks of the injection process.

[0005] Furthermore, ordinary silicone simulated skin does not perform well in mimicking the characteristics of human skin of different ages and health conditions, and cannot provide users with a diverse training environment, thus limiting the comprehensiveness and practicality of training. These factors combined make it difficult for current products to achieve ideal training results in practical applications, and further improvement and optimization are urgently needed.

[0006] The purpose of this invention is to provide a needle-free injection pressure electronic training device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a needle-free injection pressure electronic training device, comprising a silicone simulated skin layer, a pressure sensing layer, and a TPU elastic base;

[0008] The silicone simulated skin layer, pressure-sensing layer, and TPU elastic base are magnetically attached and fixed.

[0009] The pressure sensing layer includes a pressure sensing part outer shell and a pressure sensing part bottom cover.

[0010] The pressure sensing part housing contains an electrically connected pressure sensor sealing gasket, a thin-film pressure sensor, and a display component.

[0011] The bottom cover of the pressure sensing part is equipped with an electrically connected power supply battery and circuit board.

[0012] As a further improvement of this utility model: the silicone simulated skin layer includes a foamed silicone part and a foamed silicone shell, wherein the foamed silicone part is a 10A composite 5A hardness foamed silicone simulated skin.

[0014] As a further embodiment of this utility model: the simulated skin magnetic iron ring, the upper magnetic position of the pressure sensing part, the lower magnetic position of the pressure sensing part, and the magnetic position of the elastic base part are mutually attracted to each other.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model provides a needle-free injection pressure electronic trainer that utilizes a three-layer magnetic structure. The design of this three-layer magnetic structure ingeniously realizes the rapid switching between wearable injection training and non-wearable injection training. Users only need to simply adjust the combination of the magnetic components to easily adapt to different training needs.

[0019] 2. This utility model provides a product structure that accurately detects and effectively provides feedback for needle-free injection pressure training. This structure is designed to meet the needs of accurate detection of needle-free injection pressure training. By integrating a thin-film pressure sensor and a pressure feedback lamp, this design achieves simple, accurate, and rapid feedback of needle-free injection pressure, reducing the learning difficulty of needle-free injection and enhancing the safety of the injection process.

[0020] 3. This utility model uses 10A composite 5A hardness foamed silicone simulated skin, which can meet the requirements of simulated skin material for both needle-based and needle-free subcutaneous injection. The density and hardness of this material can meet the requirements of normal drug injection during both needle-based and needle-free subcutaneous injection, so that the drug can be truly injected into the skin. This simulated skin not only has a similar feel to real skin, but also simulates the slight deformation of real skin during the injection process, thereby providing a more realistic injection experience. In addition, this material also has good durability and repeatability, and can withstand multiple injection training without deformation or damage, which greatly reduces training costs.

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Reference Figures 1-5 As shown in the figure, a needle-free injection pressure electronic training device is shown in the embodiment of this utility model, including a silicone simulated skin layer 1, a pressure sensing layer 2, and a TPU elastic base 3.

[0029] Among them, the silicone simulated skin layer 1, the pressure sensing layer 2, and the TPU elastic base 3 are fixed by magnetic adsorption components;

[0030] The pressure sensing layer 2 includes a pressure sensing part housing 201 and a pressure sensing part bottom cover 202;

[0031] The pressure sensing housing 201 houses an electrically connected pressure sensor sealing gasket 206, a thin-film pressure sensor 207, and a display component. The display component includes a force feedback indicator 208 and a power indicator 209 located on the outside of the pressure sensing housing 201. A power button 203 is also located on the outside of the pressure sensing housing 201. The device is powered on using the power button 203, and needle-free training can be performed using the pressure sensor sealing gasket 206, the thin-film pressure sensor 207, the display component, and the force feedback indicator 208.

[0032] The pressure sensing part has an electrically connected power supply battery 204 and a circuit board 205 on its bottom cover 202. The power supply battery 204 is used to power the device, and the circuit board 205 is a conventional product and a necessity for electronic products. The circuit board 205 is an STM32 series microcontroller circuit board.

[0033] The silicone simulated skin layer 1 includes a foamed silicone part 101 and a foamed silicone shell 102. The foamed silicone part 101 is a 10A composite 5A hardness foamed silicone simulated skin. The density and hardness of the 10A composite 5A hardness foamed silicone simulated skin can meet the requirements of normal drug injection during both needle-based and needle-free subcutaneous injections, allowing the drug to be truly injected into the skin. This simulated skin not only has a similar feel to real skin, but also simulates the slight deformation of real skin during the injection process, thus providing a more realistic injection experience. In addition, the material also has good durability and repeatability, and can withstand multiple injection training sessions without deformation or damage, greatly reducing training costs.

[0034] Reference Figures 1-5As shown in another embodiment of this utility model, the magnetic component includes a simulated skin magnetic ring 103 disposed below the foamed silicone shell 102, an upper magnetic position 210 disposed below the pressure sensing part shell 201, a lower magnetic position 2021 disposed above the pressure sensing part bottom cover 202, and an elastic base magnetic position 301 disposed on the TPU elastic base 3. The simulated skin magnetic ring 103, the upper magnetic position 210, the lower magnetic position 2021, and the elastic base magnetic position 301 are mutually attracted. The magnetic component connects the silicone simulated skin layer 1, the pressure sensing layer 2, and the TPU elastic base 3, enabling quick switching between wearable and non-wearable injection training. Users can easily adapt to different training needs by simply adjusting the combination of the magnetic components.

[0035] Other embodiments of this utility model: The TPU elastic base 3 is provided with belt connecting buckles 4 on both sides for connecting the belt, which are used to connect the belt during later training.

[0036] The working principle of this utility model is as follows: This utility model provides a needleless injection pressure electronic trainer. When it is necessary to perform needle injection training in the abdomen, the matching belt needs to be inserted into the belt connecting buckle 4 to connect the TPU elastic base 3 to the belt. Then, the trainee needs to magnetically attach the silicone simulated skin layer 1 to the magnetic attachment position 301 of the elastic base part in the TPU elastic base 3 through the simulated skin magnetic iron ring 103, so as to achieve the modular combination of the silicone simulated skin layer 1 and the TPU elastic base 3. After that, the insulin needle injection pen can be used to directly inject training into the foamed silicone part 101.

[0037] When performing needle-free injection training in the abdomen, the matching belt must first be threaded through the belt buckle 4 to connect the TPU elastic base 3 to the belt. Then, the trainee needs to connect the silicone simulated skin layer 1 to the pressure-sensing part via the simulated skin magnetic ring 103 and the upper magnetic attachment point 210. The TPU elastic base 3 also magnetically connects with the elastic base part magnetic attachment point 301, the lower magnetic attachment point 2021 of the pressure-sensing part, and the elastic base part magnetic attachment point 301, achieving a modular connection between the silicone simulated skin layer 1, the pressure-sensing layer 2, and the TPU elastic base 3. During needle-free injection training, first press the button... The device is powered on by pressing button 203. At this time, the power supply battery 204 will supply power to the circuit board 205, thus completing the power-on process. Then, needle-free injection training can begin. The trainee needs to align the needle-free injection needle with the foamed silicone part 101 and press down. The pressure will be transmitted from the foamed silicone part 101 to the pressure sensor sealing gasket 206 and then to the thin-film pressure sensor 207. Finally, the thin-film pressure sensor 207 converts the pressure into an electrical signal and sends it to the circuit board 205. The circuit board 205 then sends different light indication signals to the force feedback indicator light 208 to indicate whether the current force is appropriate to the trainee.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
