Technical Field

[0001] This invention relates to the field of injury simulation mannequins, specifically a special injury simulation mannequin. Background Technology

[0002] In modern medical education, training qualified medical professionals is a crucial goal. With advancements in medical technology and increasing surgical complexity, the ability to respond to real-time medical emergencies has become paramount. Therefore, medical schools and hospitals are increasingly relying on simulation devices to provide practical experience, enabling students and interns to effectively handle various clinical scenarios in realistic environments. Injury simulators effectively replicate blood flow, bleeding, and physiological responses in medical emergencies. Especially in laparoscopic surgery, bleeding management is a critical skill; simulating realistic bleeding conditions helps trainees become familiar with hemostasis techniques and emergency bleeding management. By setting up different types of bleeding scenarios, trainees can learn and master these skills in a safe environment.

By simulating the torso, skin, and various simulated channels and bleeding mechanisms, trainees can operate in a near-realistic environment, enhancing their practical skills. Furthermore, by simulating different scenarios of venous and arterial bleeding, participants can learn and adapt to clinical management techniques in various situations. Through realistic laparoscopic simulations of the mouth and organs, trainees can become familiar with the procedures of laparoscopic surgery and learn how to apply necessary surgical instruments in complex surgical environments.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example: like Figures 1-6 As shown, this embodiment of the invention provides a special injury mannequin, including a simulated torso 3 and a base plate 5. A connector 16 is fixedly installed on the upper surface of the simulated torso 3, and a simulated head 2 is fixedly sleeved on the outside of the connector 16. A simulated eye hole 1 is provided near the eyes at the front end of the simulated head 2, and an electrochromic glass plate 21 is embedded inside the simulated eye hole 1. A first connecting pipe 17 and a second connecting pipe 18 are fixedly installed on one end of the simulated torso 3 near the connector 16. A simulated skin block 10 is embedded in the upper surface of the simulated torso 3, and the front and rear ends of one side of the lower surface of the simulated skin block 10 are respectively... The base plate 5 is equipped with a venous inlet tube 12 and an arterial inlet tube 13. A through hole 7 is opened at the midpoint of the upper surface of the base plate 5, and a recycling box 8 is set at the lower end of the through hole 7. A return tube 9 is fixedly set on one side of the recycling box 8. A surgical simulation block 14 is embedded in the upper surface of the simulated skin block 10. A connector 23 is fixedly set on the inner side of the two simulated arms 4 near the shoulder armor, and a cross-shaped connecting groove 25 is set on the inner side of the connector 23. A linear motor 22 is fixedly set on both sides of the simulated torso 3 near the shoulder armor, and a cross-shaped connecting block 26 is fixedly set on the output end of the linear motor 22. Specifically, an electrochromic glass plate 21 is added to the simulated eye hole 1, and the size of the light-transmitting area is controlled by voltage to simulate the state of the human pupil. A liquid inlet is reserved in the head to facilitate the quick addition of the original liquid during use, ensuring sufficient original liquid during training simulation. Simulated skin blocks 10 are attached to the simulated torso 3 to more realistically reproduce human skin, making the training use more authentic. The recycling box 8 at the bottom ensures the unified recycling of the original liquid after it flows out, avoiding pollution and waste from direct discharge.

[0018] The return tube 9 is connected to the first connecting tube 17, and the first connecting tube 17 is connected to the arterial inlet tube 13. The injury simulation surgery module 14 includes multiple first-stage endoscope opening simulation blocks 1401 and multiple second-stage endoscope opening simulation blocks 1402. The multiple first-stage endoscope opening simulation blocks 1401 are connected to each other through the second delivery tube 1404, and the multiple second-stage endoscope opening simulation blocks 1402 are connected to each other through the first delivery tube 1403. The second delivery tube 1404 is connected to the arterial inlet tube 13, and the first delivery tube 1403 is connected to the venous inlet tube 12.

[0019] Specifically, during use, the return pipe 9 re-inputs the original solution collected in the recovery box 8 into the first connecting pipe 17 and then into the arterial inlet pipe 13 to achieve recycling and generate a state of continuous and massive bleeding that simulates arterial bleeding; while the venous inlet pipe 12 and the first delivery pipe 1403 lack the function of collection and recycling, thus generating a simulated effect of less bleeding after venous bleeding during use.

[0020] Reference Figures 2-6 Both the first connecting pipe 17 and the second connecting pipe 18 are equipped with pipe joints 19 at one end inside the simulated torso 3, and both the first connecting pipe 17 and the second connecting pipe 18 are connected to the venous inlet pipe 12 and the arterial inlet pipe 13 respectively through the pipe joints 19. Specifically, the design can form two types of flowing blood vessels, namely venous and arterial vessels, to meet the display function of different bleeding effects.

[0021] One end of the second connecting tube 18, away from the venous inlet tube 12, is located at the venous inlet 1; that is, during use, the simulated vein is replenished with externally injected blood concentrate, which is not only convenient to operate, but also creates a simulation effect of a small amount of venous bleeding.

[0022] Reference Figure 3 and Figure 6 The simulated torso 3 has a simulated thoracic cavity 20 inside, which contains multiple simulated organs; a second through hole 15 is opened through one side of the lower end face of the simulated torso 3, the upper end of the second through hole 15 leads into the simulated thoracic cavity 20 and the lower end is connected to the first through hole 7. Specifically, a more realistic chest cavity simulation effect is achieved by incorporating multiple simulated organs. At the same time, the connection between the No. 1 through hole 7 and the No. 2 through hole 15 ensures that the blood-like original fluid during bleeding is collected in the recycling box 8 and forms a circulation effect.

[0023] A one-way valve is installed at one end of the reflux pipe 9 connected to the first connecting pipe 17; this can prevent the original liquid from flowing back into the delivery pipe and the simulation blocks of multiple endoscopic openings.

[0024] Reference Figures 3-5 The upper surface of the simulated skin block 10 is provided with multiple laparoscopic simulation ports 11, and multiple first-stage laparoscopic opening simulation blocks 1401 and multiple second-stage laparoscopic opening simulation blocks 1402 are respectively embedded in the multiple laparoscopic simulation ports 11. Specifically, it enables the preset processing of wound location, providing a specified opening position for simulation training, thereby achieving speed and accuracy in simulation training.

[0025] Reference Figure 1 Two cross-shaped connecting blocks 26 are connected to two cross-shaped connecting slots 25 respectively. Multiple traumatic wound modules 24 are provided on the upper surface of the two simulated arms 4, and pressure sensors are provided at the lower end of the traumatic wound modules 24. Simulated legs 6 are fixedly provided on the front and rear ends of the simulated torso 3 away from the simulated human head 2. The simulated torso 3 is fixedly set on the base plate 5. This makes the structure of the entire simulated human more human-like and more realistic.

[0026] Working principle: When this injury simulator is used for laparoscopic surgery simulation, it simulates openings according to multiple pre-set laparoscopic ports. Since there are laparoscopic opening simulation blocks inside the laparoscopic simulation ports and the laparoscopic opening simulation blocks are connected to blood-like fluid for transporting simulated blood, when the laparoscopic opening simulation block is cut open, the blood-like fluid inside flows out to simulate bleeding. The laparoscopic opening simulation blocks are divided into two types: venous bleeding and arterial bleeding. The laparoscopic opening simulation block for venous bleeding does not have a recirculating component, so the bleeding stops after a period of time, achieving a simulation process with minimal wound bleeding. The laparoscopic opening simulation block for arterial bleeding, after the bleeding simulation, has the blood-like fluid flow back into the recovery box inside the bottom plate and then flow back into the laparoscopic opening simulation block for arterial bleeding along the return pipe - No. 1 connecting pipe - No. 2 delivery pipe, thus simulating the arterial bleeding process. At the same time, depending on the position after the opening, the surgical instruments required for laparoscopic surgery can be inserted into the simulated chest cavity. Since the simulated chest cavity is equipped with simulated organs, the operation process of laparoscopic surgery can be simulated, realizing the use of surgical training to simulate special injuries of laparoscopic surgery.

[0027] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
