Description

Technical Field

[0001] This invention relates to the field of medical training devices, and more specifically to an intelligent system for training aortic balloon occlusion. Background Technology

[0002] Resuscitation balloon occlusion (REBOA) is a surgical procedure that typically involves percutaneously inserting a balloon catheter device into the blood vessel and then inflating it to control bleeding. Over the past decade, REBOA has been increasingly used to improve hemodynamic stability, increase systolic blood pressure, and control life-threatening bleeding before and / or during explicit surgical or endovascular interventional procedures.

[0003] REBOA, a minimally invasive interventional hemostasis technique, typically involves inserting a balloon catheter into the aorta via the femoral artery approach. The aortic region where the balloon needs to be placed is determined based on the bleeding site. After the balloon is inflated to block blood flow, bleeding below the blockage point is rapidly and efficiently controlled. It is suitable for the emergency treatment of patients with massive bleeding, such as non-compressible wounds to the trunk, groin, and axillary junction. This emergency interventional treatment technique requires rescuers to be proficient in the technical operation and to implement the treatment in a timely and accurate manner.

[0004] REBOA can be used to treat a variety of clinical conditions, including uncontrolled traumatic bleeding, postpartum hemorrhage, placenta accreta spectrum disorder (PAS), out-of-hospital cardiac arrest requiring cardiopulmonary resuscitation (CPR), and non-traumatic intraperitoneal bleeding, and is usually performed in non-surgical settings.

[0005] However, opportunities for skills training for rescuers in real-world clinical settings are limited, and this medical technique requires subcutaneous intervention into blood vessels, which carries inherent operational risks. Therefore, standardized training for users in this medical technique can reduce accidents caused by inexperienced medical staff and improper procedures, thereby improving clinical outcomes. Thus, there is a need for a user-friendly, reusable, and low-cost REBOA simulation training device to facilitate the widespread adoption of REBOA training. Summary of the Invention

[0006] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an intelligent system for training aortic balloon occlusion, which can simulate aortic balloon occlusion operation in a clinical environment, especially the puncture process, and has a simple structure and can be reused.

[0007] To achieve the above objectives, the present invention provides an intelligent system for training aortic balloon occlusion, comprising a human-shaped shell, an artery simulation structure, and a blood simulation mechanism. The artery simulation structure is disposed within the human-shaped shell and includes an arterial channel for simulating human arteries. The arterial channel wall has a detachable puncture portion made of an elastic and recoverable material. The puncture portion is for a puncture needle to pass through, and the puncture portion can tightly fit the puncture needle when inserted. The human-shaped shell has a puncture needle insertion area corresponding to the puncture portion, and the puncture needle insertion area is provided with a simulated skin layer made of an elastic and recoverable material. A puncture needle passing through the puncture needle insertion area can be inserted into the corresponding puncture portion. The blood simulation mechanism is connected to one end of the arterial channel near the neck and is used to provide simulated blood fluid into the arterial channel.

[0008] Furthermore, the arterial channel is transparent, and the humanoid shell is provided with a transparent observation area for observing the arterial channel.

[0009] Furthermore, the arterial channel is provided with a plug hole, and the puncture part is detachably fixedly installed in the plug hole, and the two are kept sealed.

[0010] Furthermore, the puncture portion is in close contact with the plugging hole and the contact surfaces of the two have friction, or the puncture portion is bonded to the plugging hole.

[0011] Furthermore, the material of the puncture site includes, but is not limited to, the following deformable materials: silicone, thermoplastic elastomer, ethylene-vinyl acetate elastomer, natural rubber, styrene-butadiene rubber, or butadiene rubber; the material of the simulated skin layer includes, but is not limited to, the following deformable materials: silicone, thermoplastic elastomer, ethylene-vinyl acetate elastomer, natural rubber, styrene-butadiene rubber, or butadiene rubber.

[0012] Furthermore, the blood simulation mechanism includes a reservoir and a pressure stabilizing component. The reservoir stores simulated blood liquid and is connected to one end of the arterial channel near the neck of the humanoid shell. The pressure stabilizing component is used to stabilize the pressure of the simulated blood liquid entering the arterial channel.

[0013] Furthermore, the pressure stabilizing component includes an inflation component and a first pressure detection element installed in the reservoir. The inflation component can pressurize the reservoir by filling it with gas, and the first pressure detection element is used to detect the pressure inside the reservoir. Alternatively, the pressure stabilizing component includes a delivery pump with constant pressure output capability, and the delivery pump is connected to the reservoir and the arterial channel.

[0014] Furthermore, the pressure stabilizing component includes an inflation component and a first pressure detection element installed in the liquid storage tank, and the blood simulation mechanism also includes a pressure regulating control unit. The first pressure detection element is a pressure sensor and is communicatively connected to the pressure regulating control unit, which is controlled and connected to the inflation component.

[0015] Furthermore, it also includes a switch valve located on the arterial channel at the leg of the humanoid shell, the switch valve being used to control the outflow of simulated blood liquid in the arterial channel; the pressure regulating control unit of the blood simulation mechanism is connected to the switch valve control.

[0016] Furthermore, it also includes a second pressure detection device disposed on the arterial channel located at the leg of the humanoid shell, the second pressure detection device being used to detect the pressure of the simulated blood liquid in the arterial channel before the switching valve.

[0017] As described above, the intelligent system for training aortic balloon occlusion according to the present invention has the following beneficial effects:

[0018] 1. It can effectively simulate the REBOA procedure, especially the puncture process. It is easy to operate, and the puncture site can be used for multiple punctures. After the puncture site is replaced regularly, the entire system can be reused for a long time. It has a simple structure and low cost, which is conducive to promoting REBOA training.

[0019] 2. The blood simulation device can stably provide the required blood simulation fluid, adjust and stabilize the pressure, and better simulate various clinical situations. Through the automated joint control of the inflation component, the first pressure detection device, the second pressure detection device and the switching valve, it can simulate various situations, especially the intravascular blood pressure state in the case of blood loss and the simulation of skin blood vessels within the femoral artery puncture range, which is closer to the real clinical situation.

[0041] See Figure 1 and Figure 2 This invention provides an intelligent system for training aortic balloon occlusion, comprising a human-shaped shell 1, an artery simulation structure 2, and a blood simulation mechanism 3. The artery simulation structure 2 is disposed within the human-shaped shell 1 and includes an artery channel 21 for simulating human arteries. The wall of the artery channel 21 has a detachable puncture portion 211, which is made of an elastic and recoverable material. The puncture portion 211 is used for a puncture needle to pass through, and the puncture portion 211 can tightly fit the puncture needle when it is inserted. The human-shaped shell 1 has a puncture needle insertion area 11 corresponding to the puncture portion 211, and the puncture needle insertion area 11 is provided with a simulated skin layer made of an elastic and recoverable material. A puncture needle passing through the puncture needle insertion area 11 can be inserted into the corresponding puncture portion 211. The blood simulation mechanism 3 is connected to one end of the artery channel 21 near the neck 12 and is used to provide simulated blood liquid into the artery channel 21.

[0042] This invention relates to an intelligent system for training in aortic balloon occlusion (REBOA). The size of the humanoid housing 1 can be designed according to actual needs, and the puncture section 211 in the arterial channel 21 can also be set in a suitable position and size according to actual needs. When the puncture section 211 is connected to its surrounding wall, the connection is sealed to ensure the airtightness of the entire arterial channel 21. For each puncture section 211, a corresponding puncture needle insertion area 11 is provided on the humanoid housing 1, with the puncture section 211 located below the puncture needle insertion area 11. When aortic balloon occlusion (REBOA) simulation training is required, the blood simulation mechanism 3 is opened, providing simulated blood liquid into the arterial channel 21. The trainee inserts a puncture needle through the puncture needle insertion area 11 on the humanoid housing 1 and through the corresponding puncture section 211 into the arterial channel 21. Then, the balloon is placed in the designated area to simulate the operation. The simulated skin layer can simulate the feeling of puncturing human skin, providing a more realistic simulation of the puncture process. The puncture section 211 can simulate the process of puncturing an artery, and it fits tightly against the puncture needle to ensure a seal after puncture. It recovers well after needle removal and can be reused for repeated punctures. Furthermore, the puncture section 211 is detachable, allowing for replacement with a new one after multiple training sessions, enabling long-term use. Therefore, the intelligent system for aortic balloon occlusion training of this invention can effectively simulate aortic balloon occlusion procedures in a clinical setting, especially the puncture process. It is easy to operate, and long-term reuse is possible by periodically replacing the puncture section 211. It has the advantages of simple structure and low cost.

[0043] See Figures 1 to 2 The present invention will be further described below with reference to a specific embodiment:

[0044] In this embodiment, see Figure 1 and Figure 2As a preferred design, the humanoid shell 1 only includes the main torso from the upper body to the thighs 13, excluding the limbs and head. The upper body of the humanoid shell 1 can be hollowed out, with the artery simulation structure 2 disposed within it. Preferably, the artery simulation structure 2 also includes a base 22 installed inside the humanoid shell 1, with the artery channel 21 mounted on the base 22. The humanoid shell 1 has a transparent observation area for observing the artery channel 21. The transparent observation area can be selected in a suitable position and size according to actual needs, and can be made of transparent plastic material to facilitate observation of the internal artery channel 21. In this embodiment, the lower body of the humanoid shell 1 (mainly including the legs 13) can be covered with a simulated skin layer. Of course, the simulated skin layer can also only cover the puncture needle insertion area 11 and its surrounding area. Preferably, the simulated skin layer is also installed in a detachable manner, allowing for replacement. The elastic and recoverable materials used to simulate the skin layer include, but are not limited to, silicone, thermoplastic elastomer (TPE), ethylene-vinyl acetate elastomer (EVA), natural rubber (NR), styrene-butadiene rubber (SBR), or cis-butadiene rubber (BR), etc., which are required to have appropriate elasticity and deformation recovery ability so that the hole created after the puncture needle is removed will automatically close.

[0045] In this embodiment, see Figure 1 and Figure 2 As a preferred design, since REBOA procedures involve puncture through the femoral artery in the lower body, a puncture point 211 is provided at the arterial channel 21 of the simulated femoral artery (located at the leg 13 of the humanoid shell 1). In other locations, puncture points 211 can be provided in the corresponding areas for puncture training. Preferably, the arterial channel 21 has a plug hole, and the puncture point 211 is detachably and fixedly installed in the plug hole. The puncture point 211 is similar to an elastic plug, pressing against the wall of the plug hole and creating frictional contact between the two. The puncture point 211 is stably installed by tightening and ensuring a seal. During normal use, the friction between the puncture point 211 and the plug hole can resist the pressure inside the arterial channel 21, preventing detachment. Replacement is simple: just pull out the old puncture point 211 and insert the new one. In other embodiments, the puncture part 211 and its surrounding tube wall structure can also be bonded together and sealed with sealant; the puncture part 211 can also be fixedly installed in the plug hole by means of buckles, etc. By using the buckle structure provided on the arterial channel 21, it can be pressed against the top surface of the puncture part 211 near the edge, which can fix the puncture part 211 in the plug hole, making it easy to disassemble, and at the same time does not affect the puncture needle passing through the top surface of the puncture part 211.

[0046] In this embodiment, see Figure 1 and Figure 2As a preferred design, the elastic, recoverable material used for the puncture section 211 includes, but is not limited to, silicone, thermoplastic elastomer (TPE), ethylene-vinyl acetate elastomer (EVA), natural rubber (NR), styrene-butadiene rubber (SBR), or butadiene rubber (BR), etc., and is required to have suitable elasticity and deformation recovery ability so that the hole created after the puncture needle is withdrawn will automatically close. The other parts of the arterial channel 21, excluding the puncture section 211, can be made of the same material as the puncture section 211, or they can be made of rigid plastic or other materials, without limitation. More preferably, the arterial channel 21 is also preferably transparent to facilitate observation of the internal condition.

[0047] In this embodiment, see Figure 1 and Figure 2 As a preferred design, based on the actual application of REBOA, the arterial channel 21 includes three regions: Region I, Region II, and Region III. Region I refers to the area between the left subclavian artery and the celiac artery; Region II refers to the area between the celiac artery and the renal artery; and Region III refers to the area between the terminal renal artery and the aortic bifurcation. Region I is used to block bleeding from important abdominal organs, ruptured mesenteric arteries, and vessels near the aortic bifurcation. Region III is used to block bleeding from the pelvis or lower extremities. Region II is usually not blocked. Preoperatively, an appropriately sized balloon and a sheath of appropriate length must be selected according to the area to be blocked. Preferably, the humanoid shell 1 and the arterial channel 21 are marked with schematic graduations indicating the regions I, II, and III, facilitating training for different segment occlusion procedures.

[0048] In this embodiment, see Figure 1 and Figure 2As a preferred design, the blood simulation mechanism 3 includes a reservoir 31 and a pressure stabilizing component. The reservoir 31 stores simulated blood liquid and is connected to one end of the arterial channel 21 near the neck 12 of the humanoid shell 1 (referred to as the head end). The pressure stabilizing component is used to stabilize the pressure of the simulated blood liquid supplied to the reservoir 31. The simulated blood liquid is preferably red for easy observation. The pressure stabilizing component includes an inflation component 32 installed in the reservoir 31. The inflation component 32 can specifically be a structure such as an air pump, which can pressurize the reservoir 31 by filling it with gas. By stabilizing the internal pressure of the reservoir 31, the simulated blood liquid input into the arterial channel 21 is ensured to maintain the required pressure. At this time, the head end of the arterial channel 21 can be directly connected to the reservoir 31, and the simulated blood liquid is automatically discharged into the arterial channel 21 by the internal pressure of the reservoir 31. Furthermore, the blood simulation mechanism 3 also includes a pressure regulating control unit. The first pressure detection element 33 is a pressure sensor and is communicatively connected to the pressure regulating control unit. The pressure regulating control unit is controlled by the inflation component 32. The pressure regulating control unit automatically controls the air intake of the inflation component 32 based on the pressure signal transmitted from the first pressure detection element 33, thereby automatically regulating the internal pressure of the reservoir 31. Alternatively, the pressure stabilizing component can be a delivery pump with constant pressure output capability, such as a gear pump or a gas-liquid booster pump. The delivery pump connects the reservoir 31 to the beginning of the arterial channel 21, delivering the simulated blood liquid from the reservoir 31 to the beginning of the arterial channel 21. By controlling the output pressure of the delivery pump, the simulated blood liquid entering the arterial channel 21 can be maintained at the required pressure.

[0049] In this embodiment, see Figure 1 and Figure 2As a preferred design, the system also includes a switch valve 5 located on the arterial channel 21 at the leg 13 of the humanoid shell 1. The switch valve 5 can be a solenoid valve or other type of valve. It is located near the end of the arterial channel 21 (the end near the leg 13 side of the humanoid shell 1) and is used to control the opening and closing of the end of the arterial channel 21, thereby controlling the flow or non-flow of the simulated blood liquid in the arterial channel 21. The pressure regulating control unit of the blood simulation mechanism 3 is connected to the switch valve 5. Preferably, the system also includes a collection tank 6 connected to the end of the arterial channel 21, and the switch valve 5 can control the discharge of the simulated blood liquid into the collection tank 6. A second pressure detection element 4 is also provided on the arterial channel 21 at the leg 13 of the humanoid shell 1. The second pressure detection element 4 is used to detect the pressure of the simulated blood liquid in the arterial channel 21 before the switch valve 5. The second pressure detection element 4 can also be a pressure sensor and transmits the pressure signal to the pressure regulating control unit as a pressure regulating reference condition. The arterial channel 21 branches at the leg 13, forming two external iliac arteries that extend into the femoral artery, thus having two ends. In this embodiment, one end of the arterial channel 21 in the leg 13 is provided with a switch valve 5, a second pressure detection element 4, and a collection tank 6, while the other end of the arterial channel 21 in the leg 13 is blocked with a plug 7. Of course, this end can also be provided with a switch valve 5, a second pressure detection element 4, and a collection tank 6 as needed.

[0050] The intelligent system for aortic balloon occlusion training in this embodiment enables automated integrated control of the inflation component 32, the first pressure detection element 33, the second pressure detection element 4, and the switching valve 5. During training, multiple modes can be selected according to actual needs, such as the blood pressure mode for a healthy human body (blood simulated fluid pressure of 100 mmHg) and the blood pressure mode for a blood loss condition (blood simulated fluid pressure of 30 mmHg) (these are just examples to illustrate that the pressure values ​​can be adjusted according to training needs). If the first pressure detection element 33 detects that the pressure in the collection tank 6 does not reach the standard, the inflation component 32 pressurizes the system. If the pressure detected by the first pressure detection element 33 exceeds the set value, the switching valve 5 is opened to release some of the blood simulated fluid. During these processes, the second pressure detection element 4 continuously monitors the pressure data of the blood simulated fluid near the end of the arterial channel 21.

[0051] As can be seen from the above, the intelligent system for training aortic balloon occlusion of the present invention has the following beneficial effects:

[0052] 1. It can effectively simulate the REBOA procedure, especially the puncture process. It is easy to operate, and the puncture head 211 can be used for multiple punctures. After the puncture head 211 is replaced regularly, the entire system can be reused for a long time. It has a simple structure and low cost, which is conducive to promoting REBOA training.

[0053] 2. The blood simulation mechanism 3 can stably provide the required blood simulation fluid, and can adjust and stabilize the pressure to better simulate various clinical situations. Furthermore, through the automated joint control of the inflation component 32, the first pressure detection component 33, the second pressure detection component 4, and the switching valve 5, it can simulate various situations, especially the intravascular blood pressure state in the case of blood loss and the simulation of skin blood vessels within the femoral artery puncture range, which is closer to the real clinical situation.

[0054] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
