[0002] The catheterization model is a medical device used by medical professionals during internships to help students better understand medical injections, enemas, and catheterization procedures. It simulates the human physiological structure and can effectively increase the proficiency of medical professionals in practical operations.

[0003] However, conventional catheterization models simulate fixed physiological structures, requiring model replacement during practice, which takes more time. Furthermore, conventional models do not effectively detect the movement of medical instruments within the intestines, hindering accurate monitoring and preventing users from fully understanding the precision of the procedure. Therefore, we propose a new catheterization model. Utility Model Content

This invention aims to provide a more convenient model that simulates male and female physiological structures, saves time spent on model replacement, and allows for the monitoring of the progress of catheters and endoscopes, transmitting data to instruments in a timely manner. This enables users to better understand the current insertion status of medical instruments within the intestine.

[0006] Furthermore, the model body is made of silicone material, the injection port penetrates the model body and is connected to the through hole, and the cross-sectional diameter of the injection port is less than or equal to the injection hole diameter of the syringe.

[0007] Furthermore, the cover plate is made of silicone material, and the diameter of the cover plate is greater than or equal to the cross-sectional diameter of the groove where the injection port is located. The enema port penetrates the model body and is connected to the through hole.

[0008] Furthermore, the connecting plate is made of silicone material, and a protrusion is installed on the top of the connecting plate, which is then secured to the model body. The urinary inlet includes a vaginal opening shape and a penis shape.

[0009] Furthermore, the intestinal connection port is provided with several ports, the intestinal connection port is connected to the through hole, the urinary catheter connection port is connected to the through hole, and the processor includes a wireless signal transmitter and a circuit board.

[0040] like Figures 1 to 4As shown, the model body 1 is made of silicone material, which is soft and can better simulate human skin, increasing realism. The injection port 3 penetrates the model body 1 and communicates with the through hole 12. The cross-sectional diameter of the injection port 3 is less than or equal to the injection hole diameter of the syringe, facilitating syringe insertion. The cover plate 4 is made of silicone material, and the diameter of the cover plate 4 is greater than or equal to the cross-sectional diameter of the groove where the injection port 3 is located. The enema port 5 penetrates the model body 1 and communicates with the through hole 12. The connecting plate 6 is made of silicone material, and a protrusion is installed on the top of the connecting plate 6, which is then secured within the model body 1. The urinary catheter port 7 includes a vaginal opening shape and a penile shape. The intestinal connection... Several openings 8 are provided to increase the selectivity of injection sites.
