Description

Technical Field

[0001] The invention designs a training model, and specifically relates to an interactive indwelling needle simulation training model and a simulation training method thereof. Background Art

[0002] Traditional peripheral catheter training is mostly assisted by clinical teachers. Currently, learning and simulation training are achieved through simulation training models, such as the venous puncture model disclosed in the patent document with application number 202320840298.1, which includes a simulated skin layer, simulated blood vessels and simulated subcutaneous tissue layer. The patent document with application number 201922082720.8 discloses an indwelling needle puncture arm teaching model, including an arm module similar to the shape of a human arm, a rubber tube, an elastic tape and a pair of infusion pumps. The currently existing simulation training models disclosed in the above patent documents have a relatively simple structure, resulting in only completing operations during training, without the judgment of objective data, which makes the trainees still feel confused and stressed when facing actual operations.

[0003] Most models are not intelligent enough to use, and the puncture angle and speed of the indwelling needle cannot be accurately measured. For example, application number 202020267709.9 discloses a visual indwelling needle angle model. By setting an angle bracket, trainees can more intuitively understand the insertion angle of the indwelling needle when in use, and the data measurement is not intelligent enough. In summary, the current indwelling needle puncture training model does not provide effective training feedback on the trainee's puncture speed and puncture angle, resulting in low efficiency of training or teaching. Summary of the invention

[0007] Two miniature cameras are arranged near the proximal end of the main body of the venous puncture model, and the two miniature cameras can simultaneously record the puncture images, and the interactive output is the puncture angle;

[0008] A plurality of first sensors for obtaining the first position of the indwelling needle are arranged at the puncture entrance of the simulated skin layer. The first sensors are tactile sensors, which can obtain the puncture force of the indwelling needle and drive two miniature cameras to immediately take a picture of the needle insertion moment to obtain the puncture angle of the indwelling needle while the indwelling needle is puncturing.

[0009] A plurality of second sensors for obtaining the second position of the indwelling needle are arranged around the outer periphery of the simulated blood vessel, and a plurality of third sensors with different distances from the puncture entrance are arranged on the inner wall of the simulated blood vessel, and the third sensors are used to obtain the third position of the indwelling needle;

The interactive control system compares the operation training data according to the standard operation parameters in the preset puncture mode, and can feedback the puncture angle and puncture speed of this operation training to the trainee, and can also provide the trainee with data on puncture force and needle insertion depth.

[0012] Further, the interactive control system includes: a data processing module, an interactive control module, a data analysis module, a power supply module and an interactive output module;

[0013] The interactive control module controls the operation of the data processing module, the data analysis module, the power supply module and the interactive output module through a signal circuit;

[0014] The data processing module is used to obtain the first position data and force data transmitted by the first sensor, the second position data transmitted by the second sensor, the third position data transmitted by the third sensor, the coordinates of each point on the edge of the simulated skin layer surface puncture entrance and the coordinates of each point on the edge of the indwelling needle in the puncture picture, and classify and organize them into second data to be transmitted to the data analysis module;

[0022] Step 5: The data analysis module can transmit the calculated third data to the interactive output module;

[0023] Step 6: The interactive control module controls the interactive output module through a signal circuit to feedback and display the third data in a human-computer interaction mode.

[0024] Furthermore, the puncture angle in the interactive indwelling needle simulation model can be identified by the interactive control system through different numbers; the interactive control system can provide feedback to the trainee on the puncture angle by comparing the needle angle parameters, thereby further adding an item of training information that the trainee can obtain.

[0025] Furthermore, the interactive indwelling needle simulation model also includes a calibration and debugging system, which is connected to the interactive control system through circuit signals; the calibration and debugging system can regularly remind cleaning, checking and calibrating the parameters in the model to ensure that the model is always in the best working state. At the same time, the human-computer interaction design also makes it easier for users to operate and maintain.

[0026] The beneficial effect of the present invention is to provide an interactive indwelling needle simulation training model and a simulation training method thereof.

The interactive control system compares the operation training data according to the standard operation parameters in the preset puncture mode, and can provide the trainer with the puncture angle and puncture speed of this operation training, and can also provide the trainer with the data of puncture force and needle insertion depth. Compared with the traditional puncture model, it can not only provide the trainer with information on whether the operation is qualified, but also provide whether the puncture angle is correct and the deviation value, which provides important information for the trainer to improve the operation after the training, and can greatly improve the effectiveness of the trainer's learning and training, thereby improving the efficiency of simulation training.
