Description

Technical Field

[0001] The utility model relates to the field of thoracentesis training modules, in particular to a thoracentesis simulation training module. Background Art

[0002] The chest puncture training module is a training module that uses a torso model tool to conduct chest puncture teaching simulation training. Thoracentesis is a common clinical operation, which is to directly penetrate the pleural cavity from the anterior chest wall through a puncture needle or catheter to extract pleural effusion.

[0003] Currently, most of the existing cavity puncture training modules on the market are conducted through manual teaching demonstrations with the help of a single torso model, and lack the corresponding sensor system module internally. When trainees are conducting simulation training, it is difficult to accurately demonstrate whether their process is correct and point out their errors for on-the-spot correction, which reduces the efficiency of training.

[0004] Therefore, the utility model provides a thoracentesis simulation training module to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

The internal air bag and water bag and the connecting tube fixedly installed on the air bag and the water bag, the other end of the connecting tube is respectively fixedly provided with an inflation valve and a micro water pump; by using the torso model for simulation experiments, the teaching window is convenient for displaying the anatomical structures of each layer of the chest wall, including muscles, blood vessels, nerves, etc., so that the instructor can perform a simulated thoracentesis operation at the teaching window, which is convenient for reasonable demonstration of teaching. After the teaching is completed, the trainees perform thoracentesis in the operation area and closed thoracic drainage in the drainage area to ensure the efficiency and accuracy of the practice.

[0009] In order to achieve the accuracy of the puncture and drainage simulation experiment, the torso model also includes a calibration component arranged in the operation area and the drainage area; the insertion position can be calibrated and judged by the calibration component.

[0010] Preferably, in order to achieve more accurate calibration; the calibration component includes a secondary iron mesh fixedly arranged inside the operating area and the drainage area and located outside the air bag and the water bag, a telescopic spring fixedly arranged on the side of the secondary iron mesh away from the air bag and the water bag, and a primary iron mesh fixedly installed on the side of the telescopic spring away from the secondary iron mesh; when the trainee operates in the operating area, the puncture needle or drainage tube can be inserted into the operating area and the drainage area first. At this time, in order to avoid the deviation of puncture and drainage, the primary iron mesh can be used for limit calibration through the calibration component.

[0011] Preferably, in order to realize real-time monitoring and judgment of experimental results, monitoring can be carried out by setting up sensors; the calibration component also includes an electromagnetic sensor fixedly arranged on the side of the secondary iron mesh close to the fixed iron plate and a socket opened on the fixed iron plate for puncture and drainage; during the calibration process, the puncture needle and the drainage needle are inserted into the socket opened on the internal fixed iron plate along the primary iron mesh, which is correctly inserted; when they are inserted into the fixed iron plate, it is incorrectly inserted. At this time, the fixed iron plate will be driven to squeeze the telescopic spring to make the side of the fixed iron plate close to the secondary iron mesh close to the electromagnetic sensor on the secondary iron mesh, thereby affecting the magnetic field to facilitate the electromagnetic sensor to output signals and facilitate later monitoring.

[0012] Preferably, in order to achieve reasonable electronic monitoring, the thoracentesis simulation training module also includes a simulation system for simulating puncture and drainage training; and the simulation result judgment can be realized through the simulation system.

[0013] Preferably, in order to achieve reasonable systematization; the simulation system includes a control terminal, a processor arranged inside the control terminal, and an electromagnetic sensor connected to the input end of the processor; when the puncture needle or drainage tube is inserted incorrectly, the electromagnetic sensor receives the phenomenon of magnetic field change and transmits it to the external processor.

When the insertion position is correct, the fixed iron plate will not contact the electromagnetic sensor and the alarm will not sound an alarm.

[0015] (III) Beneficial effects

[0016] The thoracentesis simulation training module determines the puncture and drainage positions by setting up a simulation system and utilizing calibration components and the simulation system, thereby improving the efficiency of thoracentesis simulation training.

[0030] When in use, by using the torso model 1 to perform a simulation experiment, since the teaching window 11 is convenient for displaying the anatomical structures of various layers of the chest wall, including muscles, blood vessels, nerves, etc., the instructor can perform a simulated thoracentesis operation in the teaching window 11, which is convenient for reasonable demonstration of teaching. After the teaching is completed, the trainees perform thoracentesis in the operation area 12 and closed thoracic drainage in the drainage area 13. In order to ensure the efficiency and accuracy of the practice, the simulated puncture and drainage insertion positions can be calibrated through the calibration component 5, and the air bag 3 and the water bag 4 are punctured by the puncture needle and the drainage needle respectively to complete the puncture and drainage simulation. At the same time, after the experiment is completed, the air bag 3 at the puncture site is inflated by the air valve 2, and the water bag is replenished with water through the connecting tube by a micro water pump, which is convenient for repeated simulations at a later time.

[0031] Specifically, the calibration component 5 includes a secondary iron mesh 52 fixedly arranged inside the operating area 12 and the drainage area 13 and located outside the air bag 3 and the water bag 4, a telescopic spring 54 fixedly arranged on the side of the secondary iron mesh 52 away from the air bag 3 and the water bag 4, and a primary iron mesh 51 fixedly installed on the side of the telescopic spring 54 away from the secondary iron mesh 52; when the trainee operates in the operating area 12, the puncture needle or drainage tube can be inserted into the operating area 12 and the drainage area 13 first. At this time, in order to avoid the puncture and drainage interlacing deviation, the calibration component 5 can be used to perform limit calibration using the primary iron mesh 51.

[0032] Furthermore, the calibration component 5 also includes an electromagnetic sensor 55 fixedly arranged on the side of the secondary iron mesh 52 close to the fixed iron plate 53 and a socket 56 for puncture and drainage opened on the fixed iron plate 53; the training results can be displayed through the control terminal 32; during the calibration process, the puncture needle and the drainage needle are inserted into the socket 56 opened on the internal fixed iron plate 53 along the primary iron mesh 51, which is correctly inserted; when they are inserted into the fixed iron plate 53, it is incorrectly inserted. At this time, the fixed iron plate 53 will squeeze the telescopic spring 54 to make the side of the fixed iron plate 53 close to the secondary iron mesh 52 close to the electromagnetic sensor 55 on the secondary iron mesh 52, thereby affecting the magnetic field to facilitate the electromagnetic sensor 55 to output a signal, which is convenient for later monitoring.

When the insertion position is correct, the fixed iron plate 53 will not contact the electromagnetic sensor 55, and the alarm will not sound an alarm.
