Description

Technical Field

[0001] The present application relates to the technical field of injection models, and in particular to a facial high-precision injection practice training system. Background Art

[0002] In the field of facial medicine, precise facial injection technology is essential to achieve safe and effective treatment. Traditional facial filler injections usually rely on the doctor's experience and skills, but in the context of pursuing higher precision and consistency, micro-dose injection technology has developed rapidly. Injections in delicate facial areas, such as lips, around the eyes and other sensitive areas, require extremely high precision to ensure treatment effectiveness and patient safety. In recent years, with the development of microelectronics technology and precision machinery, devices capable of 0.05 ml injections have emerged. Such devices are particularly important for facial beauty treatments because they can help doctors shape facial contours more finely, reduce the risk of side effects, and improve overall satisfaction with treatment.

[0003] Facial injections can be done manually or automatically with the help of an electronic booster. Accurate facial injection technology is crucial to achieving safe and effective treatment. New doctors and nurses often lack practical experience, and there are certain risks in practicing injections directly on real faces. Therefore, there is an urgent need for a simulation training system that combines software and hardware to train doctors and nurses to master the skills of 0.05 ml precision injections on the human face. The device needs to be able to simulate various parameters in the actual injection process, including needle penetration depth measurement and injection volume measurement functions. Summary of the invention

[0007] Furthermore, it also includes a controller, a start-stop button and a touch screen integrated on the side of the electronic booster. The signal input end of the controller is electrically connected to the potential sensor, the start-stop button and the touch screen, and its signal output end is electrically connected to the axial boost structure and the tension and closing structure.

[0008] Based on the above technical solution, a layered facial simulation sample was designed, which cooperated with the needle and injection liquid of the syringe to achieve the measurement of injection accuracy.

[0009] Furthermore, it also includes an electronic booster for installing the syringe, the electronic booster has an axial booster structure built in, and its output end is connected to the push rod of the syringe;

[0010] Based on the above technical solution, by adding an electronic booster, the simulation of electronic push injection of the syringe is realized when practicing facial simulated sample injection, wherein the electronic booster uses a conventional electronic booster in the prior art; by matching special training needles and special training injection fluids, the liquid pressure feedback at different insertion depths and injection volumes can be simulated.

In addition, the damping control component also needs to simulate the real resistance feedback during injection to help trainees better understand and master the injection skills.

[0012] Based on the above technical solution, the resistance of piercing the skin during injection can also be simulated with the help of a damping control component, which is linked to a potential sensor. When different levels of potential sensors are triggered, the damping control component triggers different damping force sizes, thereby simulating the actual damping effect of the skin.

[0013] Furthermore, the electronic booster includes a housing and a limit cover threadedly connected thereto, the limit cover is sleeved on the syringe; a telescopic rod is provided at the output end of the axial booster structure, the end of the telescopic rod passes through the housing, and the end is clamped on the push rod of the syringe.

[0014] Furthermore, the damping member includes a C-shaped plate arranged on one side of the telescopic rod, a spring is arranged between its open ends, an electric drive member with an output end connected to the wedge-shaped push plate is installed on its closed side, and both sides of the wedge-shaped push plate slide and abut against the inner side of the opening of the C-shaped plate respectively.

[0015] Furthermore, the opening sides of the two C-shaped plates are rotatably connected to the first sliding plate and the second sliding plate respectively; a limiting groove is radially opened at the bottom of the warehouse body, and the other ends of the first sliding plate and the second sliding plate are slidably arranged in the limiting groove, and the sides of the two sliding plates are abutted against the telescopic rod.

[0016] Furthermore, a positioning protrusion is provided between the central positions of adjacent simulation layers, and a positioning structure composed of a limiting protrusion and a limiting groove plugged into each other is provided at the edge thereof.

[0017] Furthermore, the end of the limiting protrusion and the bottom of the limiting groove are configured as mutually matching inclined surface structures.

[0018] Furthermore, the damping member also includes a guide block arranged on the other side of the telescopic rod, the inner side of which is an arc surface structure and is axially slidably connected to the telescopic rod.

[0019] In summary, this application includes the following beneficial technical effects:

[0038] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0039] The embodiment of the present application discloses a facial high-precision injection practice training system.

In this structure, the damping control component 6 includes a guide block 601 and a damping member 602. The damping member 602 is provided with an opening and closing structure. The damping force on the telescopic rod 204 in the electronic booster 2 is adjusted through the opening and closing structure to simulate the hand resistance during injection.

[0044] The side of the electronic booster 2 is integrated with a start / stop button 1 and a touch screen 4. The signal input end of the controller 7 is also electrically connected to the start / stop button 1 and the touch screen 4, and its signal output end is electrically connected to the axial boosting structure 203 and the opening / closing structure.

[0045] Example 3

[0046] Reference Figures 3 to 9 , and based on the above embodiment, this embodiment further discloses a facial high-precision injection practice training system, the electronic booster 2 includes a warehouse body 201 and a limit cover 202 threaded therewith, the limit cover 202 is sleeved on the syringe 3, and the output end of the axial booster structure 203 is provided with a telescopic rod 204, the end of the telescopic rod 204 passes through the warehouse body 201, and its end is clamped on the push rod of the syringe 3. In this structure, by setting the damping ratio of the damping member 602 and linking it to the controller 7, the damping force of the telescopic rod 204 at different depths is changed according to the input of the potential sensor 8, thereby realizing the simulation of pressure feedback when piercing different depths and injection volumes.
