Description

Technical Field

[0001] The utility model relates to the technical field of medical simulation, in particular to a simulation display device for the formation of thrombus. Background Art

[0002] A thrombus refers to a solid mass of material formed in a blood vessel, usually composed of components such as platelets, red blood cells and fibrin. The formation of a thrombus is usually the body's response to injury or bleeding, but when a thrombus forms inappropriately or excessively in a blood vessel, it can cause blood flow obstruction, thereby affecting the supply of oxygen and nutrients. This situation may cause a series of health problems, such as myocardial infarction, stroke or deep vein thrombosis. The prevention and treatment of thrombosis usually requires a combination of medication, lifestyle adjustments and other measures.

[0003] The specification of Chinese utility model patent CN221378762U discloses a thrombus simulation device, including a peristaltic pump, a simulated blood vessel, a liquid storage device, a pressure chamber, a pressure source, and a controller, wherein: the simulated blood vessel is a tube structure, including a tube body, a liquid inlet, and a liquid outlet, and at least a portion of the tube body is configured as an elastic body, and the liquid inlet and the liquid outlet are connected to the peristaltic pump and the liquid storage device through pipelines to form a loop; the pressure chamber is configured as a cavity structure, and the tube body passes through the pressure chamber and extends outward to expose the liquid inlet and the liquid outlet; the pressure source is connected to the pressure chamber to control the pressure in the pressure chamber, and the controller is connected to the peristaltic pump and the pressure source. The pressure source provides high pressure to the pressure chamber, causing the elastic body to squeeze into the simulated blood vessel to simulate vascular stenosis and thrombosis.

[0004] In the above patent, the elastic tube is simply squeezed to increase the internal pressure, thereby simulating the state in which the blood vessel pressure increases due to thrombus blockage, and the specific formation process of the thrombus is not displayed in detail. Therefore, the simulation effect is poor, which affects the teaching and demonstration effects. Therefore, a simulation display device for thrombus formation is proposed. Utility Model Content

[0028] The following will be combined with the Figures 1 to 6 This utility model is described in detail, and the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the embodiments described are only some of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.

[0029] The present invention provides a device for simulating and displaying the formation of thrombus by improving the present invention. Figure 1 - Figure 6As shown, the display assembly 1 includes a display box 101, and a blood transfusion simulation assembly 3 simulating a blood vessel is installed inside the display box 101. The blood transfusion simulation assembly 3 includes a semicircular tube 301 for simulating a blood vessel. The rear side wall of the semicircular tube 301 is connected to two infusion tubes 302, one of which is connected to a water pump 303. A transparent plate 304 is fixedly connected between the front side wall of the semicircular tube 301 for simulating a blood vessel and the front inner wall of the display box 101. An elastic sheet 305 for simulating a venous valve is fixedly connected to the interior of the semicircular tube 301 for simulating a blood vessel. The upper end of the semicircular tube 301 is connected to a triggering thrombus simulation assembly 4 for simulating a thrombus.

[0030] In this embodiment, when demonstration is required, the water pump 303 is started to allow the blood simulating liquid 103 to flow into the semicircular tube 301 for simulating a blood vessel through the infusion tube 302 and then be discharged from another infusion tube 302, thereby simulating the normal flow of blood inside the semicircular tube 301 for simulating a blood vessel.

[0031] In the above embodiment, in order to simulate the blood coagulation factor, the following method can be used:

[0032] The display component 1 also includes an inclined plate 102 fixedly connected to the inside of the display box 101. The display box 101 is filled with blood simulation liquid 103. A display photo 104 is fixedly connected between the front inner wall of the display box 101 and the transparent plate 304. On the one hand, the display photo 104 can shield the triggered thrombus simulation component 4. At the same time, the display photo 104 can also display a picture of blood vessel wall damage, simulating blood vessel wall damage, making the simulation more realistic and helping people understand more easily. A plurality of coagulation factor simulation components 2 are arranged inside the blood simulation liquid 103. The coagulation factor simulation component 2 includes an air bag 201. The air bag 201 can increase the buoyancy of the magnetic block 202 to a certain extent, so that the coagulation factor simulation component 2 can better flow with the blood simulation liquid 103. A magnetic block 202 is arranged inside the air bag 201.

[0033] In a preferred embodiment, when the blood simulating liquid 103 flows, the blood coagulation factor simulation component 2 will flow together, thereby simulating the normal flow state of the blood coagulation factor.

[0034] refer to Figure 4 and Figure 5In a preferred embodiment, the thrombus triggering simulation component 4 includes a connecting tube 401 fixedly connected to the upper side wall of the semicircular tube 301 for blood vessel simulation, a ball core 402 is rotatably connected inside the connecting tube 401, a placement groove 403 is drilled at the upper end of the ball core 402, a clamping block 404 is slidably connected inside the ball core 402, a thrust spring 405 is fixedly connected between the clamping block 404 and the ball core 402, a pull rope 406 is provided between the clamping block 404 and the ball core 402, a magnetic ball block 407 fixedly connected to the pull rope 406 is provided inside the placement groove 403, a motor 408 is fixedly connected to the rear side wall of the connecting tube 401, and the output end of the motor 408 is fixedly connected to the ball core 402, an electromagnet 5 is fixedly connected to the front side wall of the display box 101, and the electromagnet 5 is magnetically connected to the clamping block 404.

[0035] In this embodiment, the motor 408 drives the ball core 402 to rotate 180 degrees, so that the magnetic ball block 407 can rotate into the interior of the semicircular tube 301 for vascular simulation. Figure 1 As shown, at this time, the magnetic ball block 407 can rely on magnetic force to absorb multiple coagulation factor simulation components 2 in the blood simulation liquid 103, thereby simulating thrombosis. Subsequently, the staff can also start the electromagnet 5, so that the electromagnet 5 relies on magnetic repulsion to push the clamp 404, causing the pull rope 406 to fall off. At this time, the magnetic ball block 407 is no longer fixed and flows with the blood simulation liquid 103 until the blood simulation liquid 103 hits the venous valve simulation elastic sheet 305 and stops, thereby simulating the state of blockage caused by blood passing through the venous choroid after the thrombus falls off.

[0036] It is worth noting that, under normal circumstances, the diameter of the coagulation factor simulation component 2 can smoothly pass through the gap of the elastic sheet 305 for venous valve simulation, but after multiple coagulation factor simulation components 2 are gathered together, they cannot pass through the gap of the elastic sheet 305 for venous valve simulation. In addition, a window for removing the coagulation factor simulation component 2 is installed on the left wall of the display box 101. After the coagulation factor simulation component 2 is removed, it can be placed back in the placement slot 403. By starting the electromagnet 5 to move the clamp 404, the pull rope 406 is placed in the gap between the clamp 404 and the ball core 402. After turning off the electromagnet 5, the clamp 404 can be used to clamp the pull rope 406, thereby completing the fixation of the magnetic ball block 407 and achieving the purpose of reusing the magnetic ball block 407.

[0037] Working principle: Start the water pump 303 to extract the blood simulation liquid 103, so that the blood simulation liquid 103 can flow inside the semicircular tube 301 for blood vessel simulation, and at the same time drive multiple blood coagulation factor simulation components 2 to flow together. The staff then starts the motor 408, and the motor 408 drives the ball core 402 to rotate 180 degrees, so that the magnetic ball block 407 absorbs multiple blood coagulation factor simulation components 2, simulating the process of blood vessel wall damage and blood coagulation to form a thrombus. After that, the staff starts the electromagnet 5, so that the electromagnet 5 pushes the clamp 404, causing the magnetic ball block 407 to fall off from the ball core 402 under gravity and the flow of blood simulation liquid 103, and hit the elastic sheet 305 for venous valve simulation, so as to simulate the process of thrombus falling off and blood vessel blockage, making the simulation more realistic.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
