Description

Technical Field

[0001] The present invention relates to the field of medical technology equipment, in particular to a portable medical electric push injection device. Background Art

[0002] In the medical field, accurate, safe and convenient drug injection operations are crucial to patients' treatment effects and recovery process. Traditional medical injection methods, such as manual syringes, can meet basic injection needs to a certain extent, but they have many limitations. The operation of manual syringes depends entirely on the experience and hand strength control of medical staff, and it is difficult to ensure that the strength, speed and dosage of each injection are accurate and consistent. This not only increases the workload of medical staff, but may also affect the effect of drug injection due to operational differences, and even cause medical risks.

[0003] With the continuous development of medical technology, electric push injection devices have emerged, bringing new solutions to drug injection. Electric push injection devices use motor drive to achieve drug injection, which can improve the accuracy and stability of injection to a certain extent and reduce the workload of medical staff. However, the existing medical electric push injection devices on the market still have some problems that need to be solved urgently.

[0004] On the one hand, in terms of ease of assembly and use, some electric push-in injection devices lack a quick and secure way to secure the pressing and pushing mechanisms. In clinical applications, medical staff need to frequently install, disassemble, and adjust the various components of the device to accommodate different treatment needs and operating scenarios. If the securing method between the pressing and pushing mechanisms is complex or insecure, it will not only increase the difficulty and time cost of medical staff's work, but may also cause components to loosen or shift during operation, affecting the normal operation of the device and the accuracy of the injection.

[0005] On the other hand, the existing electric push injection devices still have room for improvement in terms of the accuracy and safety of injection operations. Different injection drugs and injection scenarios have different requirements for pressing force, but most existing devices lack an effective force feedback mechanism, making it difficult for medical staff to accurately grasp the appropriate pressing force. This may lead to insufficient pressing force during the injection process, resulting in the drug being unable to be effectively injected; or excessive pressing force, causing unnecessary pain to the patient, and even leading to complications. In addition, in terms of the adaptability of the injection mechanism to syringes of different specifications, some devices cannot be flexibly adjusted to accommodate syringes of various sizes, limiting their versatility in actual clinical applications.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the new embodiments of the system. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] Example: like Figures 1-13As shown, the present invention provides a portable medical electric push injection device, It includes an injection mechanism 1, a pressing mechanism 2, and a pushing mechanism 3. The pressing mechanism 2 is arranged on the pushing mechanism 3, and the injection mechanism 1 is arranged on the pushing end of the pushing mechanism 3. The pushing mechanism 3 is used to drive the injection mechanism 1 to perform an injection operation, and the pressing mechanism 2 is used to drive the pushing mechanism 3 to perform a pushing operation. The pressing mechanism 2 includes a pressing handle 4, a bracket 5, and a pressing rod 6. The bracket 5 is provided on the pushing mechanism 3. The pressing handle 4 is hingedly provided on the bracket 5. The pressing rod 6 is provided at the lower end of the pressing handle 4. Pressing the pressing handle 4 downward drives the pressing rod 6 downward. The pushing mechanism 3 includes a shell 7, a trigger mechanism 8, a motor, and a screw rod. The motor is arranged in the shell 7. One end of the screw rod is connected to the output shaft of the motor. The other end of the screw rod passes through one end side wall of the shell 7 and is connected to the injection mechanism 1. The trigger mechanism 8 is arranged on the shell 7 and is electrically connected to the motor. The pressing rod 6 presses the trigger mechanism 8 downward, thereby driving the motor to turn on. The motor drives the screw rod to move, thereby driving the injection mechanism 1 to perform injection operation.

[0030] The present application forms a complete and coordinated injection system by combining the injection mechanism 1, the pressing mechanism 2 and the pushing mechanism 3. The pushing mechanism 3 serves as the power core, providing precise driving force for the injection mechanism 1, ensuring the stability and accuracy of the injection operation, and effectively avoiding the injection speed and dosage fluctuation problems caused by uneven force in manual injection. The pressing mechanism 2 is arranged on the pushing mechanism 3, and the pushing mechanism 3 is triggered by pressing the handle 4 to drive the pressing rod 6 downward. This operation method is simple and intuitive. Medical staff only need to apply appropriate downward pressure to start the injection, which greatly reduces the difficulty of operation and improves work efficiency. It is especially suitable for the needs of fast and accurate injection in emergency medical scenarios.

[0031] Optionally, a quick fixing mechanism is provided between the pressing mechanism 2 and the pushing mechanism 3, and the quick fixing mechanism is located at the junction of the bracket 5 and the shell 7. A fixing plate 9 is provided on the left and right sides of the bracket 5, and the surface of the fixing plate 9 fits the surface of the shell 7. The quick plug-in mechanism is located between the fixing plate 9 and the surface of the shell 7. The quick plug-in mechanism includes a support rod 10, a positioning rod 11, and a positioning plate 12. One end of the support rod 10 is fixedly connected to the side wall of the shell 7. The support rods 10 are provided in several groups, and several groups of the support rods 10 are distributed in a circular shape on the surface of the shell 7. One end of the positioning rod 11 is fixed to the surface of the shell 7 and is located between the circles surrounded by several groups of the support rods 10. The positioning plate 12 is provided with a first positioning groove 13 and a second positioning groove 14, and the positioning plate 12 is in contact with the surface of the fixing plate 9. The other end of the support rod 10 extends to the left side of the positioning plate 12 through the first positioning groove 13, and the other end of the positioning rod 11 extends to the left side of the positioning plate 12 through the second positioning groove 14. A first clamping mechanism is provided on the support rod 10, and a second clamping mechanism is provided on the positioning rod 11. The first clamping mechanism and the second clamping mechanism jointly press the positioning plate 12, so that the positioning plate 12 is fixed to the surface of the fixing plate 9, thereby achieving the fixation of the fixing plate 9 and the surface of the shell 7, thereby achieving the fixation between the pressing mechanism 2 and the pushing mechanism 3.

[0032] A quick fixing mechanism is provided between the pressing mechanism 2 and the pushing mechanism 3, which greatly improves the assembly convenience and structural stability of the device. The quick fixing mechanism is located at the junction of the bracket 5 and the shell 7. Through the close fit between the fixing plate 9 and the surface of the shell 7, and the coordinated action of the support rod 10, the positioning rod 11 and the positioning plate 12 in the quick plug-in mechanism, the pressing mechanism 2 and the pushing mechanism 3 are quickly and accurately fixed, so that medical staff can quickly complete the assembly and disassembly of the device during clinical operations, saving valuable time. At the same time, the first clamping mechanism and the second clamping mechanism work together to apply clamping force to the positioning plate 12 from multiple directions, ensuring the firmness of the connection between the pressing mechanism 2 and the pushing mechanism 3, effectively preventing loosening or displacement during use, and ensuring the smooth progress of the injection operation.

[0033] Optionally, the first clamping mechanism includes a first clamping plate 15 and a first clamping ring 16. The first clamping plate 15 includes a first straight portion 17 and a first curved portion 18. The first curved portion 18 is arranged at one end of the first straight portion 17. A first through hole is penetrated through the first straight portion 17. The first through hole is located at the end of the first straight portion 17 away from the first curved portion 18. The first straight portion 17 is inserted into the support rod 10 through the first through hole. The first curved portion 18 is used to clamp the side wall of the positioning plate 12. The upper end of the support rod 10 is provided with a thread. The first clamping ring 16 is threadedly connected to the upper end of the support rod 10. The first clamping ring 16 is tightened downward, thereby squeezing the first straight portion 17, thereby driving one end of the first straight portion 17 to retract toward the center of the positioning plate 12, thereby driving the first curved portion 18 to clamp and fix the side wall of the positioning plate 12.

[0034] The first clamping mechanism adopts a combined structure of a first clamping plate 15 and a first clamping ring 16 to achieve efficient clamping and fixing of the positioning plate 12. The first straight portion 17 of the first clamping plate 15 is inserted into the support rod 10 through the first through hole, and the first curved portion 18 cleverly clamps the side wall of the positioning plate 12. This structure not only ensures the stability of the clamping, but also facilitates installation and disassembly. The first clamping ring 16 is threadedly connected to the upper end of the support rod 10. By tightening it downward, it can accurately squeeze the first straight portion 17 so that one end of it is retracted toward the center of the positioning plate 12, thereby driving the first curved portion 18 to tightly clamp and fix the side wall of the positioning plate 12. This adjustable clamping method can flexibly adjust the clamping force according to actual conditions, ensuring that the fixing effect between the positioning plate 12 and the surface of the fixing plate 9 is optimal, further enhancing the reliability of the connection between the pressing mechanism 2 and the pushing mechanism 3.

[0035] Optionally, the second clamping mechanism includes a second clamping plate 19, a third clamping plate 20, and a second clamping ring 21. The second clamping plate 19 includes a second straight portion 22 and a second curved portion 23. The second curved portion 23 is arranged at one end of the second straight portion 22. A second through hole is opened through the second straight portion 22. The second through hole is located at the end of the second straight portion 22 away from the second curved portion 23. The second straight portion 22 is inserted into the positioning rod 11 through the second through hole. The second curved portion 23 is used to clamp the side wall of the positioning plate 12. The upper end of the positioning rod 11 is provided with a thread. The second clamping ring 21 is screwed The groove is connected to the upper end of the positioning rod 11, and the third clamping plate 20 has the same structure as the second clamping plate 19 and is inserted into the positioning rod 11. The second clamping plate 19 and the third clamping plate 20 jointly clamp the left and right side walls of the positioning plate 12, and tighten the second clamping ring 21 downward to squeeze the second straight portion 22, thereby driving one end of the second straight portion 22 to converge toward the center of the positioning plate 12, and then driving the second curved portion 23 to clamp and fix the side wall of the positioning plate 12, thereby driving the second clamping plate 19 and the third clamping plate 20 to jointly clamp and fix the left and right side walls of the positioning plate 12.

[0036] The second clamping mechanism is composed of a second clamping plate 19, a third clamping plate 20 and a second clamping ring 21, which provides a more comprehensive and stable guarantee for the fixation of the positioning plate 12. The second clamping plate 19 and the third clamping plate 20 have the same structure and are jointly plugged into the positioning rod 11. They can apply clamping force from the left and right ends of the positioning plate 12 at the same time to ensure the stability of the positioning plate 12 in the horizontal direction. The matching design of the second curved portion 23 and the second straight portion 22, and the squeezing effect of the second clamping ring 21 on the second straight portion 22 through a threaded connection enable the second curved portion 23 to tightly clamp and fix the side wall of the positioning plate 12. At the same time, the coordinated work of the second clamping plate 19 and the third clamping plate 20 further enhances the clamping and fixing effect, effectively preventing the positioning plate 12 from being offset or loosened due to force during the injection process, and ensuring the stability of the overall structure of the device and the accuracy of the injection operation.

[0037] Optionally, the pressing handle 4 is provided with a force feedback mechanism, which includes a force sensor 24, a microprocessor 25 and a prompt module 26; The force sensor 24 is provided at the connection between the pressing handle 4 and the pressing rod 6, and is used to detect in real time the force with which the user presses the pressing handle 4, and transmit the detected force signal to the microprocessor 25. The microprocessor 25 is provided inside the housing 7, and has a built-in force threshold database. The force threshold database presets multiple force threshold ranges according to different injection drugs and injection scenarios. The microprocessor 25 compares and analyzes the received force signal with the data in the force threshold database. The prompt module 26 is provided on the surface of the pressing handle 4, and the prompt module 26 includes an LED indicator and a micro vibration motor. When the microprocessor 25 determines that the force with which the user presses the pressing handle 4 is within the appropriate force threshold range, the LED indicator turns green. When the force is too low, the LED indicator lights up yellow and the micro vibration motor vibrates intermittently to remind you. When the force is too great, the LED indicator light turns red and the micro vibration motor vibrates continuously and strongly to remind the user, thereby ensuring that the user can accurately grasp the appropriate pressing force and guarantee the accuracy and safety of the injection operation.

[0038] The setting of the force feedback mechanism significantly improves the safety and accuracy of the injection operation. The force sensor 24 detects the force of the user pressing the handle 4 in real time and transmits the data to the microprocessor 25. The built-in force threshold database of the microprocessor 25 presets multiple force threshold ranges according to different injection drugs and injection scenarios, and can accurately judge whether the current pressing force is appropriate. The prompt module 26 provides the user with intuitive and clear feedback information through a combination of LED indicator lights and micro vibration motors. When the pressing force is within the appropriate range, the LED indicator lights up green, prompting the user to operate correctly; when the force is too small, the yellow indicator light and intermittent slight vibration remind the user to increase the force appropriately; when the force is too large, the red indicator light and continuous strong vibration warn the user to reduce the force in time. This real-time force feedback mechanism can help medical staff accurately grasp the appropriate pressing force, avoid injection failure or harm to patients due to improper force, and ensure the accuracy and safety of the injection operation.

[0039] Optionally, the trigger mechanism 8 is set as a trigger button. Setting the trigger mechanism 8 as a trigger button simplifies the operation process of the device and improves the convenience of use. The trigger button has a clear operation mark and intuitive tactile feedback. When the medical staff presses the pressing handle 4, the pressing rod 6 can accurately and quickly press the trigger button, thereby starting the motor to drive the screw to move and realize the injection operation. This simple and direct operation method reduces the learning cost and operation difficulty of medical staff, and is particularly suitable for quickly starting injections in emergency situations, thereby improving the efficiency and response speed of medical operations.

[0040] Optionally, the quick fixing mechanism is provided in at least two groups, and the two groups of quick fixing mechanisms are respectively located on the left and right sides of the bracket 5. The quick fixing mechanism is provided in at least two groups and respectively located on the left and right sides of the bracket 5, which further enhances the stability and reliability of the connection between the pressing mechanism 2 and the pushing mechanism 3. The two groups of quick fixing mechanisms fix the pressing mechanism 2 from different directions, effectively dispersing the various forces generated during use, and avoiding loosening or damage caused by excessive force on a single fixing point. The symmetrical layout design not only improves the overall structural strength of the device, but also makes the connection between the pressing mechanism 2 and the pushing mechanism 3 more balanced and stable, ensuring the stability and durability of the device during long-term and high-frequency use, and providing reliable protection for clinical injection operations.

[0041] The pressing mechanism 2 and the pushing mechanism 3 of the present application are firmly connected through a quick fixing mechanism. With the help of the support rod 10, the positioning rod 11, the positioning plate 12 and the matching clamping assembly, medical staff can quickly complete the assembly and disassembly of the various components of the device without the need for complex tools or tedious steps, significantly saving operation time. It is especially suitable for quickly building injection equipment in emergency medical scenarios to gain precious treatment time for patients. The device adopts a modular design concept, with each component having independent functions and standardized interfaces, which makes it convenient for medical staff to flexibly replace or adjust components according to actual needs, further improving the convenience and flexibility of operation.

[0042] The trigger mechanism 8 is set as an intuitive trigger button with clear operating logic. Medical staff can start the device by simply pressing it down, which lowers the operating threshold and reduces the risk of human error. It is especially suitable for non-professionals or quick operations in emergency situations. The pressing handle 4 is ergonomically designed and has an anti-slip texture on the surface to ensure that medical staff have a comfortable hand and a firm grip during long-term operation, avoiding operational errors caused by hand fatigue.

[0043] The force feedback mechanism monitors the force applied to the pressing handle 4 in real time through the force sensor 24, and combines with the built-in force threshold database of the microprocessor 25 to accurately determine whether the current pressing force meets the requirements of different drugs and scenarios. The combined feedback of the green / yellow / red LED indicator lights and the micro-vibration motor provides intuitive and immediate operation guidance for medical staff to ensure that the pressing force is always within a safe and effective range. It supports flexible adjustment of the force threshold parameters through external devices or built-in menus according to conditions such as drug type, patient age and injection site, thereby realizing personalized injection control and meeting diverse clinical needs.

[0044] The pushing mechanism 3 adopts a motor-driven screw structure. Through the coordinated movement of the high-precision motor and the screw, the millimeter-level displacement control of the piston in the syringe is achieved, ensuring that the injection speed and dosage of the liquid medicine are accurately controlled, and avoiding fluctuations in the treatment effect caused by uneven injection speed or dosage errors.
