Description

Technical Field

[0001] The utility model relates to the field of medical training devices, in particular to a resuscitative aortic balloon occlusion simulation training device. Background Art

[0002] Resuscitative balloon occlusion of the aorta (REBOA) is a surgical procedure in which a balloon catheter device is introduced into a blood vessel, usually percutaneously, and then inflated 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 definitive surgical or endovascular intervention.

[0003] REBOA is a minimally invasive interventional hemostasis technology that often uses a balloon catheter to be inserted into the aorta via the femoral artery. The area of ​​the aorta where the balloon needs to be inserted is determined based on the bleeding site. After the balloon is inflated to block blood flow, bleeding below the blockage point is quickly and efficiently controlled. It is suitable for emergency treatment of patients with massive bleeding, such as hemorrhage from non-compressible trunk, groin, and axillary junction trauma. This emergency interventional treatment technology requires the rescuer to be proficient in the technical operation essentials and to implement 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 (PAS), out-of-hospital cardiac arrest requiring cardiopulmonary resuscitation (CPR), and non-traumatic intra-abdominal hemorrhage, and is usually performed in non-surgical settings.

[0005] However, opportunities for skill training for rescuers in real-world clinical settings are limited. Furthermore, this medical technique requires subcutaneous puncture to access a blood vessel, which carries certain operational risks. Therefore, standardized training for users on this medical technique can reduce accidents caused by inexperience and improper operation, thereby improving clinical outcomes. Therefore, a low-cost, easy-to-use, reusable REBOA simulation training device is needed to facilitate the promotion of REBOA training. Utility Model Content

[0041] See also Figure 1 and Figure 2The utility model provides a resuscitative aortic balloon occlusion simulation training device, comprising a humanoid shell 1, an arterial simulation structure 2 and a blood simulation mechanism 3. The arterial simulation structure 2 is arranged in the humanoid shell 1, and comprises an arterial channel 21 for simulating a human artery. The wall of the arterial channel 21 has a detachable puncture portion 211, and the puncture portion 211 is made of an elastically recoverable material. The puncture portion 211 is used for a puncture needle to pass through, and when the puncture needle is inserted, the puncture portion 211 can fit tightly with the puncture needle; a puncture needle insertion area 11 corresponding to the puncture portion 211 is provided on the humanoid shell 1, and the puncture needle insertion area 11 is provided with a simulated skin layer made of an elastically recoverable material. The 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 arterial channel 21 close to the neck 12, and is used to provide blood simulation liquid to the arterial channel 21.

[0042] The present invention relates to a simulated training device for resuscitative balloon occlusion of the aorta. The scope of the humanoid shell 1 can be designed according to actual needs. The puncture portion 211 in the arterial channel 21 can also be set at an appropriate position and size range according to actual needs. When the puncture portion 211 is connected to the surrounding tube wall, the connection is sealed, ensuring the sealing of the entire arterial channel 21 wall. For each puncture portion 211, a corresponding puncture needle area 11 is provided on the humanoid shell 1. The puncture portion 211 is located below the puncture needle area 11. When a simulated training for resuscitative balloon occlusion of the aorta (REBOA) is required, the blood simulation mechanism 3 is opened and blood-simulating liquid is provided to the arterial channel 21. The trainee inserts the puncture needle through the puncture needle area 11 on the humanoid shell 1 and through the corresponding puncture portion 211 into the arterial channel 21. The balloon is then placed in the designated area, thereby simulating the operation process. The simulated skin layer can simulate the feeling of puncturing human skin, simulating the puncture process more realistically. The puncture part 211 can simulate the process of puncturing an artery, and the puncture part 211 can fit tightly with the puncture needle to ensure the sealing after puncture. It can recover well after the puncture needle is pulled out and can be used repeatedly for puncture. At the same time, the puncture part 211 adopts a detachable design. After multiple operation trainings, a new puncture part 211 can be replaced and it can continue to be used for a long time. Therefore, the resuscitative aortic balloon occlusion simulation training device of the present invention can well simulate the aortic balloon occlusion operation in the clinical environment, especially the puncture process. It is easy to operate and can be reused for a long time by regularly replacing the puncture part 211. It has the advantages of simple structure and low cost.

[0043] See also Figures 1 to 2 The present invention is further described below with a specific embodiment:

[0044] In this embodiment, see Figure 1 and Figure 2 As a preferred design, the humanoid shell 1 only includes the main trunk from the upper body to the thigh 13, and does not include the limbs and head. The upper body of the humanoid shell 1 can be hollowed out, and the artery simulation structure 2 is disposed therein. Preferably, the artery simulation structure 2 also includes a base 22 mounted within the humanoid shell 1, and the arterial channel 21 is mounted on the base 22. The humanoid shell 1 is provided with a transparent observation area for observing the arterial channel 21. The transparent observation area is selected in an appropriate position and size according to actual needs. Specifically, it can be made of a transparent plastic material to facilitate observation of the internal arterial 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 area 11 and its surrounding area. The simulated skin layer is preferably also installed in a detachable manner so that it can be replaced. The elastic 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 butadiene rubber (BR), etc., and are required to have appropriate elasticity and deformation recovery capabilities 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 surgery is performed by puncturing the femoral artery of the lower body, a puncture portion 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 parts, if puncture training is required, a puncture portion 211 can be provided in the corresponding area. Preferably, a plug hole is provided in the arterial channel 21, and the puncture portion 211 is detachably fixedly installed in the plug hole. The puncture portion 211 is similar to an elastic plug, squeezing the plug hole wall and causing frictional contact between the two. The puncture portion 211 is stably installed by plugging and ensures sealing. During normal use, the friction between the puncture portion 211 and the plug hole can resist the pressure in the arterial channel 21 and will not detach. When replacing, you only need to pull out the old puncture portion 211 with force and insert the new puncture portion 211. In other embodiments, the puncture portion 211 and the surrounding tube wall structure can also be glued and sealed with sealant; the puncture portion 211 can also be fixed in the plug hole by means of snaps, etc., and the snap structure provided on the arterial channel 21 is pressed against the top surface of the puncture portion 211 near the edge, so that the puncture portion 211 can be fixed in the plug hole, which is convenient for disassembly and does not affect the puncture needle passing through the top surface of the puncture portion 211.

[0046] In this embodiment, see Figure 1 and Figure 2As a preferred design, the elastic and recoverable material used in the puncture portion 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 appropriate elasticity and deformation recovery capabilities so that the hole created after the puncture needle is removed will automatically close. The other parts of the arterial channel 21, except for the puncture portion 211, can be made of the same material as the puncture portion 211, or can be made of materials such as hard plastic, without limitation. Further preferably, the arterial channel 21 is also preferably transparent to facilitate observation of the internal situation.

[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 areas: Area I, Area II, and Area III, where Area I refers to the area between the left subclavian artery and the celiac artery, Area II refers to the area between the celiac artery and the renal artery, and Area III refers to the area between the end of the renal artery and the aortic bifurcation. Area I is used to block bleeding from important abdominal parenchymal organs, rupture of the mesenteric artery, and blood vessels near the aortic bifurcation. Area III is used to block bleeding from the pelvis or lower limbs, and Area II is usually not blocked. Before the operation, a balloon of appropriate size and a sheath of appropriate length should be selected according to the area to be blocked. Preferably, a schematic scale for the division of Area I, Area II, and Area III is provided on the humanoid shell 1 and the arterial channel 21 to facilitate the trainer to carry out training on the occlusion of different sections.

[0048] In this embodiment, see Figure 1 and Figure 2As a preferred design, the blood simulation mechanism 3 includes a liquid reservoir 31 and a pressure stabilizing assembly. The liquid reservoir 31 stores a blood-simulating liquid and is connected to the end of the arterial channel 21 near the neck 12 of the humanoid shell 1 (denoted as the head end). The pressure stabilizing assembly is used to stabilize the pressure of the blood-simulating liquid provided by the liquid reservoir 31. The blood-simulating liquid is preferably red for easier observation. The pressure stabilizing assembly includes an inflatable component 32 mounted on the liquid reservoir 31. The inflatable component 32 can specifically be an air pump or other structure that can fill the liquid reservoir 31 with gas to pressurize it. By stabilizing the internal pressure of the liquid reservoir 31, the blood-simulating liquid input into the arterial channel 21 is ensured to maintain the required pressure. In this case, the head end of the arterial channel 21 can be directly connected to the liquid reservoir 31. The internal pressure of the liquid reservoir 31 automatically discharges the blood-simulating liquid into the arterial channel 21. Furthermore, the blood simulation mechanism 3 also includes a pressure regulation control unit. The first pressure detection component 33 is a pressure sensor and is communicatively connected to the pressure regulation control unit. The pressure regulation control unit is controllably connected to the inflatable component 32. The pressure regulating control unit automatically controls the air intake of the inflatable component 32 based on the pressure signal transmitted by the first pressure detecting element 33, thereby automatically regulating the pressure within the liquid reservoir 31. Alternatively, the pressure stabilizing component may be a delivery pump capable of outputting a constant pressure, such as a gear pump or a gas-liquid booster pump. The delivery pump is connected to the liquid reservoir 31 and the head end of the arterial channel 21. The delivery pump delivers the blood simulating liquid in the liquid reservoir 31 to the head end of the arterial channel 21. By controlling the output pressure of the delivery pump, the desired pressure of the blood simulating liquid entering the arterial channel 21 can be maintained.

[0049] In this embodiment, see Figure 1 and Figure 2As a preferred design, the device further includes an on-off valve 5 disposed on the arterial channel 21 located at the leg 13 of the humanoid shell 1. Specifically, the on-off valve 5 can be a solenoid valve or other type of valve. The on-off valve 5 is disposed near the end of the arterial channel 21 (the end near the leg 13 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 blood-simulating liquid in the arterial channel 21. The pressure regulation control unit of the blood-simulating mechanism 3 is controllably connected to the on-off valve 5. Preferably, the device further includes a liquid collection tank 6 connected to the end of the arterial channel 21. The on-off valve 5 can control the discharge of the blood-simulating liquid into the liquid collection tank 6. A second pressure detection element 4 is also disposed on the arterial channel 21 located at the leg 13 of the humanoid shell 1. The second pressure detection element 4 is used to measure the pressure of the blood-simulating liquid in the arterial channel 21 before the on-off valve 5. The second pressure detection element 4 can also be a pressure sensor, which transmits the pressure signal to the pressure regulation control unit as a pressure regulation reference condition. The arterial channel 21 will bifurcate at the leg 13 to form two external iliac arteries, which then extend into the femoral artery, so it has two ends. In this embodiment, a switch valve 5, a second pressure detection component 4 and a liquid collecting tank 6 are provided at the end of the arterial channel 21 in one of the legs 13, and the end of the arterial channel 21 in the other 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 component 4 and a liquid collecting tank 6 as needed.

[0050] Using the resuscitative aortic balloon occlusion simulation training device of this embodiment, the inflatable component 32, the first pressure detection component 33, the second pressure detection component 4, and the switch valve 5 can realize automated integrated control. During the training process, multiple modes can be selected according to actual needs. For example, the blood pressure mode for a healthy person: the blood simulation liquid pressure is 100mmHg, and the blood pressure mode under blood loss: the blood simulation liquid pressure is 30mmHg (only listed values ​​are intended to illustrate that the pressure value can be adjusted according to the needs of training). If the first pressure detection component 33 detects that the pressure in the collection tank 6 does not meet the standard, the inflatable component 32 is pressurized. If the pressure monitored by the first pressure detection component 33 exceeds the set value, the switch valve 5 is opened to release some of the blood simulation liquid. During these processes, the second pressure detection component 4 constantly monitors the pressure data of the blood simulation liquid near the end of the arterial channel 21.

[0051] As can be seen from the above, the resuscitative aortic balloon occlusion simulation training device of the present invention has the following beneficial effects:

[0052] 1. It can well simulate the REBOA operation process, especially the puncture process, and is easy to operate. The puncture part 211 can be used for multiple punctures. After the puncture part 211 is replaced regularly, the entire device 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 liquid, adjust and stabilize the pressure, and better simulate various clinical situations. Moreover, through the automated coordinated control of the inflatable component 32, the first pressure detection component 33, the second pressure detection component 4, and the switch valve 5, it is possible to simulate various situations, especially the intravascular blood pressure state in the case of blood loss and the simulation of skin blood vessels within the range of femoral artery puncture, which is closer to the actual clinical situation.

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

[0055] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may 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 one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
