[0025] In order to more clearly and completely understand the technical solutions of the present application, the specific embodiments of the present application will be described in detail below with reference to the drawings. It should be noted that the following embodiments are only further explanations of the present application and do not constitute a limitation on the present application. Those skilled in the art can adjust and deform the technical solutions in the embodiments without departing from the concept of the present application, and these adjustments and deformations should also be considered as the protection scope of the present application.

[0026] Embodiment one:

[0027] The present embodiment provides an insulin injection device, which is based on the needle-free injection technology and combines precise dose control and intelligent data transmission function, so as to realize more comfortable, convenient and efficient insulin injection.

[0028] Needle-free injection module 100

[0029] Figure 2 Figure 1 is a schematic diagram of a needle-free injection module of an insulin injection device according to an embodiment of the present application; as shown, the needle-free injection module 100 is one of the core components of the device, and its main function is to inject the drug liquid from the injection chamber 102 at high speed through high-pressure gas, in the form of spray, directly into the patient's body. The design of this module enables insulin to enter the patient's skin at a precise dose and speed, without the need for traditional needle puncture, thereby reducing the pain of the patient during injection. Figure 2

[0030] The needle-free injection module 100 includes an injection chamber 102 and an injection port 101. The inner wall of the injection chamber 102 is coated with a special material to reduce the resistance of the drug liquid during injection, ensuring that the insulin can pass smoothly. At the same time, the aperture of the injection port 101 is precisely designed to ensure that the particle size of the insulin after atomization is appropriate, which can efficiently penetrate the skin without causing damage to the skin. A sensor 501 is installed near the injection port 101 for real-time monitoring of the injection speed. The sensor 501 is connected to a micro-precision controller 500 through the data line.

[0031] In an alternative embodiment, the sensor 501 is a flow sensor or an ultrasonic sensor, which can be a micro-thermal flow sensor, a micro-Coriolis flow sensor, or a DP series ultrasonic flow sensor. These sensors can monitor the injection speed of insulin in real time.

[0032] The needle-free injection module 100 injects insulin into the subcutaneous tissue at high speed using high-pressure gas. In order to ensure that the drug liquid can penetrate the skin but not penetrate the muscle layer, the injector must accurately control the injection speed; the injection speed will affect the distribution of the drug liquid, and a faster injection speed helps the drug liquid to penetrate the skin at an appropriate speed, but if the speed is too high, it may cause the drug liquid to penetrate the muscle. Generally, the injection speed is monitored in real time by the sensor 501 and maintained within an appropriate range such as 100 to 200 m / s, which can ensure that the drug liquid stays only in the subcutaneous tissue.

[0033] High-pressure gas driving device 200

[0034] The high-pressure gas driving device 200 is a key component that provides the power required for needle-free injection. The device includes a high-pressure gas generator and an electrically controlled air pump, which controls the generation and delivery of gas to ensure that the pressure in the injection chamber 102 is stable, thereby ensuring that the drug liquid can be sprayed at an appropriate speed.

[0035] ​The high-pressure gas generator is connected with the needle-free injection module 100 through a gas pipeline, and a one-way gas pressure regulating valve is arranged in the gas pipeline to adjust the gas pressure according to the injection requirement; the one-way gas pressure regulating valve is arranged to ensure that the high-pressure gas can only flow in one direction, thereby preventing the high-pressure gas from flowing back.

[0036] It should be stated that the one-way gas pressure regulating valve arranged here is a one-way structure known in the art, and the present application only applies it here. Therefore, the structure details of the one-way regulating valve are not further disclosed in the present application.

[0037] Those skilled in the art should understand the structure used in the present application.

[0038] The medicine container 300

[0039] The medicine container 300 is used to store the insulin to be injected, and the container is detachably connected with the high-pressure gas driving device 200 or the needle-free injection module 100 through a plug-in interface, so as to facilitate replacement and maintenance. Optionally, the present embodiment is described by connecting the medicine container 300 with the high-pressure gas driving device 200.

[0040] Figure 1 is a structural schematic diagram of an insulin injection device provided by an embodiment of the present application, as shown in Figure 1 In an optional embodiment, the medicine container 300 is obliquely inserted into the high-pressure gas driving device 200; a handheld housing is arranged outside the medicine container 300, and the two have independent connection structures; that is, when disassembled, the handheld housing needs to be first disassembled, and then the medicine container 300 is pulled out. The plug-in interface of the medicine container 300 is designed as a sealed structure to prevent leakage of the medicine. Figure 3 is a schematic diagram of a medicine container of an insulin injection device provided by an embodiment of the present application, as shown in Figure 3 The medicine container 300 is designed with a piston 302 structure, the piston 302 in the medicine container 300 is fixedly connected with a piston rod of a driving motor 301, and the piston 302 is pushed by the piston rod of the driving motor 301, so that the insulin is accurately pushed into the injection cavity 102 of the needle-free injection module 100.

[0041] The medicine container 300 is designed with high sealing performance to prevent the medicine from being affected by the external environment during storage and pushing. The amount of insulin in the container can be monitored in real time by the micro-precision controller 500, and the current remaining amount of medicine is displayed on the display screen 600, so that the patient can replace the medicine container 300 in time.

[0042] The micro-precision controller 500

[0043] The micro-precision controller 500 is the core control unit of the entire device. It dynamically adjusts the working state of the high-pressure gas driving device 200, specifically the electrically controlled air pump and the driving motor 301, by processing real-time data provided by the sensor 501, to ensure that the dose and speed of each injection meet the preset values.

[0044] Specifically, the micro-precision controller 500 is connected to the electrically controlled air pump through a first control line, and is used to adjust the working state of the electrically controlled air pump according to the data collected by the sensor 501, and then adjust the speed at which the high-pressure gas generator generates high-pressure gas.

[0045] The micro-precision controller 500 is connected to the driving motor 301 through a second control line, and is used to adjust the working state of the driving motor 301 according to the data collected by the sensor 501, and then adjust the pushing speed of the insulin.

[0046] In an optional embodiment, the initial speed of the high-pressure gas and the pushing speed of the insulin are usually based on the speed parameters set by the user or the doctor. Before each injection starts, the user inputs the preset insulin dose and speed information into the micro-precision controller 500. The micro-precision controller 500 directly controls the working state of the electrically controlled air pump and the driving motor 301 according to these preset parameters, so that the injection speed remains stable at every moment during the injection process.

[0047] For example, if the user sets 5 units of insulin for each injection and requires the injection to last for 5 seconds, the micro-precision controller 500 will calculate the injection speed according to this information, and control the electrically controlled air pump to generate appropriate high-pressure gas and control the driving motor 301 to push the insulin in the medicine liquid container 300 at the required injection speed at the start of the injection.

[0048] At this time, the sensor 501 monitors the injection speed of the insulin in real time, and adjusts the working state of the electrically controlled air pump and the working state of the driving motor 301 according to the data collected by the sensor 501.

[0049] For example, if the sensor 501 detects that the injection speed is too fast or too slow, the micro-precision controller 500 can immediately adjust the output of the electrically controlled air pump, adjust the air pressure, adjust the speed at which the driving motor 301 drives the piston 302 to move, and thus correct the injection speed for the next time.

[0050] By monitoring the injection speed in real time during the injection process and continuously adjusting the working state of the electric air pump and the driving motor 301 according to the sensor 501 feedback information. In this way, the injection speed of insulin is not completely dependent on the preset parameters, but can be adjusted in real time according to the feedback of the sensor 501, ensuring that the injection process is accurate and meets the user's needs.

[0051] The micro-precision controller 500 is equipped with a user input interface, and the patient can set the insulin dose and injection speed for each injection or each day according to the doctor's advice. The micro-precision controller 500 controls the air pressure of the electric air pump and the pushing speed of the motor according to the set dose and injection speed instructions. In addition, the micro-precision controller 500 is also responsible for recording the historical data of each injection, which can be transmitted to external devices for further analysis through the data transmission module.

[0052] Display screen 600

[0053] The display screen 600 is connected with the micro-precision controller 500 through the display cable, which is used to display the working state of the device in real time, including injection dose, remaining insulin amount, device power and other information. The display screen 600 adopts touch design, and the user can directly view and set the injection parameters through the screen, which simplifies the operation process.

[0054] In addition, when the device detects abnormal conditions such as insufficient insulin amount, abnormal air pressure or low battery power, the display screen 600 will issue a warning prompt to ensure that the patient can handle it in time and avoid safety hazards during the injection process.

[0055] Data transmission module

[0056] The data transmission module is connected with the micro-precision controller 500 through the communication interface, which is used to wirelessly transmit the current injection dose of insulin, the remaining insulin dose, and the historical injection record in the micro-precision controller 500 to external devices.

[0057] The data transmission module supports wireless data transmission function, including Bluetooth and Wi-Fi connection, and the user can synchronize the data of the injection device to the smartphone or computer. Through the special application program, the patient can view the historical injection data and share the injection record with the medical staff, which is convenient for the doctor to monitor and adjust the patient's condition.

[0058] The module also supports remote diagnosis function, and the device stores and analyzes the injection data through the cloud, so that the patient can receive the injection advice of the doctor remotely, which further improves the intelligent degree of the device.

[0059] Battery module

[0060] The battery module provides power support for the entire device, and adopts lithium battery technology, with high efficiency and long endurance. The battery module supplies power to the micro-precision controller 500 through the first power line and supplies power to the high-pressure gas generator through the second power line. The battery module can be charged through the USB interface 901, and in addition, the device is also designed with a power indication function, so that users can check the remaining power of the battery at any time.

[0061] After a full charge, the device can support multiple injection operations, greatly improving the portability and convenience of use of the device.

[0062] Housing structure

[0063] The housing is made of lightweight high-strength material to ensure that the device is easy to carry and has certain impact resistance. The housing is internally provided with multiple partitions for fixing the key components such as the needle-free injection module 100, the liquid medicine container 300, the high-pressure gas generator, the micro-precision controller 500, the display screen 600, the power module, etc., to ensure the stability of the internal structure of the device and reduce the displacement or damage of the components caused by collision. The USB charging interface is arranged at the bottom of the housing.

[0064] The surface of the housing is treated with antibacterial properties to ensure that the patient is not threatened by bacterial infection during long-term use. In addition, the bottom of the housing is provided with a buckle structure to facilitate the quick installation and removal of the disposable pre-filled insulin liquid medicine container 300, thereby improving the ease of use of the device.

[0065] Example Two

[0066] On the basis of Example One, the high-pressure gas generation system and data management function of the insulin injection device are further optimized.

[0067] Two-stage gas pressure regulation system

[0068] In this embodiment, the high-pressure gas generator adopts a two-stage gas pressure regulation system. Compared with a single regulation system, the two-stage system can more accurately control the change of gas pressure, ensuring that the injection speed of insulin is more stable. Through the one-way gas pressure regulating valve, the gas pressure can be coarsely adjusted according to the injection requirements, and through the micro-precision controller 500, the output of the electric control gas pump is adjusted. The high-pressure gas generator can automatically fine-tune the injection pressure in different injection scenarios to adapt to the needs of different patient skin thickness and injection depth.

[0069] High-efficiency servo motor

[0070] The servo motor replaces the traditional drive motor 301, and the servo motor has the advantages of higher precision and efficiency. Through the feedback control system, the motor can dynamically adjust according to the actual needs during the injection process, reduce energy loss, and improve the overall endurance of the device. In addition, the stability of the servo motor in the low-power state is better than that of the ordinary motor, and it is more suitable for occasions that require precise control.

[0071] Intelligent data platform and remote monitoring

[0072] The data transmission module integrates 5G communication function, allowing patients to transmit injection data to the cloud storage platform in real time. Through connection with the remote medical system, the patient's doctor can view the injection data at any time and adjust the insulin injection dose according to the real-time feedback. This intelligent data management function not only improves the patient's self-management ability, but also provides important support for the doctor's remote monitoring and diagnosis.

[0073] Example three:

[0074] In order to further improve the portability of the device, the shell design and battery module are improved in this embodiment.

[0075] Lightweight shell design

[0076] The shell material is changed to ultra-light carbon fiber composite material, which reduces the overall weight of the device and makes it easy for patients to carry. At the same time, anti-slip design is added to the surface of the shell, improving the convenience of use of the device in various environments.

[0077] Solar charging module

[0078] In this embodiment, the battery module is additionally equipped with a solar charging device, allowing patients to charge the device through the solar panel when they are outdoors, further extending the use time of the device. This design greatly improves the portability and self-sufficiency of the device.

[0079] In summary, the present application solves the problems of traditional insulin injection devices in terms of portability, comfort and intelligence through needle-free injection technology, efficient dose control, intelligent data management function and portable design, and is suitable for a wide range of diabetic patients.

[0080] The embodiments of the present application can be widely used in the daily insulin injection management of diabetic patients, improving the safety, convenience and comfort of insulin injection.
