These devices help beginners master correct needle placement, angles, and injection depths before actual procedures, reducing the likelihood of errors.
[0003] Because there are requirements for the depth and location of the injection needle inserted into the human body during injection, existing injection simulation equipment does not have the function of detecting the needle position.

[0042] Please refer to the following: Figures 1 to 7 The injection simulation device provided in the embodiments of this application will now be described.
[0043] An injection simulation device includes a simulated arm 10, a multilayer conductive layer 20, a simulated injection needle 30, and an alarm 40.
[0044] Please see Figure 1 The simulated arm 10 is made of silicone. Multiple conductive layers 20 are disposed on the simulated arm 10 and are arranged alternately along the inner side of the simulated arm 10 toward the outer side of the simulated arm 10. Each of the multiple conductive layers 20 can be connected to a power source.
[0045] The simulated injection needle 30 includes a handheld part 31, a controller, and a needle 32. The controller is installed inside the handheld part 31, and the needle 32 is installed at one end of the handheld part 31 and electrically connected to the controller. It is inserted into the simulated arm 10 to simulate the injection process. An alarm 40 is electrically connected to the controller in the simulated injection needle 30 and is used to identify whether the needle 32 of the simulated injection needle 30 is inserted into a preset position.
[0046] When the simulated injection needle 30 passes through different conductive layers 20, the different conductive layers 20 transmit different electrical signals to the controller located inside the simulated injection needle 30 through the needle tip 32. The controller receives the different electrical signals and determines the depth and position of the needle tip 32 inserted into the simulated arm 10 based on the different electrical signals, thereby determining whether the needle tip 32 has been inserted into the preset position. All multiple conductive layers 20 are connected to a power source, and the voltage of each conductive layer 20 is different.
[0047] When the needle 32 of the simulated injection needle 30 is inserted into the preset position, the controller controls the alarm 40 to issue a message indicating that the operation is correct.
[0048] When the needle tip 32 of the simulated injection needle 30 is misaligned with the preset position, the controller controls the alarm 40 to issue an alarm signal to remind the trainee to adjust the injection angle and injection depth.
[0049] Compared with the prior art, the injection simulation device provided in this application includes a simulated arm 10, multiple conductive layers 20, a simulated injection needle 30, and an alarm 40. The multiple conductive layers 20 are all disposed on the simulated arm 10 and are arranged sequentially at intervals along the inner side of the simulated arm 10 towards the outer side. The simulated injection needle 30 is used to insert into the simulated arm 10 to simulate the injection process. The alarm 40 is electrically connected to the simulated injection needle 30 and is used to identify whether the needle tip 32 of the simulated injection needle 30 is inserted into a preset position. When the needle tip 32 of the simulated injection needle 30 is inserted into the preset position, the alarm 40 issues a correct operation message. When the needle tip 32 of the simulated injection needle 30 is misaligned with the preset position, the alarm 40 issues an alarm signal to remind the trainee to adjust the injection angle and injection depth.
[0050] In this application, please refer to Figure 1 , Figure 4 and Figure 5 The multilayer conductive layer 20 includes a first conductive layer 21, a second conductive layer 22, and a third conductive layer 23. The first conductive layer 21, the second conductive layer 22, and the third conductive layer 23 are all made of conductive fabric.
[0051] A first conductive layer 21 is disposed on the simulated arm 10. A second conductive layer 22 is disposed on the simulated arm 10, located outside the first conductive layer 21 and spaced apart from it. A silicone layer is disposed between the first conductive layer 21 and the second conductive layer 22. A third conductive layer 23 is disposed on the simulated arm 10, located outside the second conductive layer 22 and spaced apart from it. A silicone layer is also disposed between the second conductive layer 22 and the third conductive layer 23.
[0052] A first injection region is formed in the silicone layer between the first conductive layer 21 and the second conductive layer 22, and a second injection region is formed in the silicone layer between the second conductive layer 22 and the third conductive layer 23. A preset position is located in the first injection region. When the needle 32 of the simulated injection needle 30 is in the preset position, the alarm 40 issues a correct operation message. When the needle 32 of the simulated injection needle 30 is in the second injection region or on the side of the first injection region away from the second injection region, the alarm 40 issues an alarm signal.
[0053] Specifically, the first conductive layer 21 transmits a first electrical signal to the controller through the needle 32, the second conductive layer 22 transmits a second electrical signal to the controller through the needle 32, and the third conductive layer 23 transmits a third electrical signal to the controller through the needle 32. The alarm 40 is a speaker.
[0054] When the needle 32 is located in the second injection layer between the third conductive layer 23 and the second conductive layer 22, the needle 32 passes through the third conductive layer 23. The third conductive layer 23 transmits the third electrical signal to the controller through the needle 32. The controller generates a first alarm signal based on the third electrical signal and transmits the first alarm signal to the alarm device 40. The alarm device 40 issues a first alarm message based on the first alarm signal, such as an alarm message indicating that the needle 32 is inserted too shallowly into the simulated arm 10.
[0055] When the needle 32 is located in the first injection layer between the second conductive layer 22 and the first conductive layer 21, the needle 32 passes through the third conductive layer 23 and the second conductive layer 22. The third conductive layer 23 transmits the third electrical signal to the controller through the needle 32, and the second conductive layer 22 transmits the second electrical signal to the controller through the needle 32. The controller generates a simulated success signal based on the simultaneously received third and second electrical signals and transmits the simulated success signal to the alarm 40. The alarm 40 issues a simulated success message based on the simulated success signal.
[0056] When the needle 32 is located on the side of the first conductive layer 21 away from the second conductive layer 22, the needle 32 passes through the third conductive layer 23, the second conductive layer 22 and the first conductive layer 21 in sequence. The third conductive layer 23 transmits the third electrical signal to the controller through the needle 32, the second conductive layer 22 transmits the second electrical signal to the controller through the needle 32, and the first conductive layer 21 transmits the first electrical signal to the controller through the needle 32. The controller generates a second alarm signal based on the third, second and first electrical signals received simultaneously, and transmits the second alarm signal to the alarm device 40. The alarm device 40 issues a second alarm message based on the second alarm signal, such as an alarm message indicating that the needle 32 is inserted too deeply into the simulated arm 10.
[0057] Please see Figure 6 and Figure 7 In one embodiment of this application, to improve the injection accuracy of the trainee on the simulated arm 10, a fourth conductive layer 24 is provided in the first injection area. The area of the fourth conductive layer 24 is smaller than the area of the first conductive layer 21 and the second conductive layer 22, and a preset position corresponds to the position of the fourth conductive layer 24. When the needle tip 32 of the simulated injection needle 30 is located within the first injection area but outside the area where the fourth conductive layer 24 is located, the alarm 40 issues an alarm signal.
[0058] Specifically, when the needle 32 is located in the first injection area and simultaneously penetrates the third conductive layer 23, the second conductive layer 22, and the fourth conductive layer 24, the third conductive layer 23 transmits the third electrical signal to the controller through the needle 32, the second conductive layer 22 transmits the second electrical signal to the controller through the needle 32, and the fourth conductive layer 24 transmits the fourth electrical signal to the controller through the needle 32. The controller generates a simulated success signal based on the simultaneously received third, second, and fourth electrical signals and transmits the simulated success signal to the alarm 40. The alarm 40 then issues a simulated success message based on the simulated success signal.
[0059] When the needle 32 is located in the first injection area and its position is misaligned with the fourth conductive layer 24, the needle 32 simultaneously penetrates the third conductive layer 23 and the second conductive layer 22. The third conductive layer 23 transmits a third electrical signal to the controller through the needle 32, and the second conductive layer 22 transmits a second electrical signal to the controller through the needle 32. The controller generates a third alarm signal based on the simultaneously received third and second electrical signals and transmits the third alarm signal to the alarm device 40. The alarm device 40 issues a third alarm message based on the third alarm signal, such as an alarm message indicating that the needle 32 is misaligned in the simulated arm 10.

At this time, an alarm 40 is installed within the mobile terminal 50.

The mobile terminal 50 displays the screen information of the needle 32 being inserted into the second injection layer according to the first display drive signal. At the same time, the mobile terminal 50 displays the alarm information that the needle 32 is inserted too shallowly on the simulated arm 10 according to the first alarm signal to remind the trainee.

At the same time, the mobile terminal 50 displays the information of the needle 32 being successfully simulated based on the simulation success signal to prompt the trainee.
[0064] When the needle 32 is located on the side of the first conductive layer 21 away from the second conductive layer 22, the controller generates a third display drive signal based on the third electrical signal, the second electrical signal, and the first electrical signal received simultaneously, and transmits the third display drive signal and the second alarm signal to the mobile terminal 50. The mobile terminal 50 displays the image information of the needle 32 inserted into the side of the first injection layer away from the second injection layer according to the third display drive signal. At the same time, the mobile terminal 50 displays an alarm message that the needle 32 is inserted too deeply into the simulated arm 10 according to the third alarm signal, so as to remind the trainee.

Simultaneously, the mobile terminal 50 displays information about the successful simulation of the needle 32 based on the simulated success signal to alert the trainee.
