Description

Technical Field

[0001] The present technical solution relates to the technical field of medical education equipment, and in particular to an ECMO teaching model capable of intubation teaching. Background Art

[0002] ECMO, short for extracorporeal membrane oxygenation, is a complex treatment for critical care in clinical medicine. It is one of the most cutting-edge and challenging technologies and a leading provider of cardiopulmonary support therapies. For severe heart and lung diseases, when lung function is severely impaired, ECMO can take on the task of gas exchange, allowing the lungs to rest. When heart function is severely impaired, a blood pump can simulate the heart's pumping function to maintain blood circulation. ECMO is an advanced life support technology and an effective treatment for severe heart and lung diseases.

[0003] For example, Chinese patent CN211149895U discloses a model based on ECMO and IABP puncture and implantation, including a human body model and a simulated blood pipeline arranged in the human body model. The simulated blood pipeline includes a venous tube and an arterial tube that follow the direction of human veins and arteries and are interconnected through a booster device. The device simulates the capillaries at the end of the human limbs and is also detachably provided with a puncture block, which includes simulated skin and subcutaneous tissue for use in puncture practice.

[0004] Existing ECMO teaching models generally have limitations and mainly provide routine vascular puncture teaching and skills training. The effect of this teaching model is relatively simple, lacks simulation of complex clinical scenarios, and has poor applicability to real rescue processes. It is difficult to effectively improve the clinical response ability and decision-making level of the students, resulting in poor teaching results and needs to be improved. Summary of the Invention

[0005] In order to improve the problem that the teaching mode of conventional vascular puncture training is relatively single and leads to poor teaching effect, this technical solution provides an ECMO teaching model that can be used for intubation teaching.

[0006] The purpose of this technical solution is achieved in this way:

[0007] An ECMO teaching model capable of intubation teaching includes a simulation model body with a chest cavity opened inside;

[0008] a lung model mounted in the chest cavity;

[0009] A head model, which is arranged at the front end of the simulation model body and is connected to the open end of the chest cavity;

[0010] The pseudo-trachea structure is arranged inside the head model, one end of which is connected to the lung model and the other end of which is formed with an oral cavity corresponding to the face of the head model for ventilator intubation.

[0011] Through the above technical solution, when the ECMO teaching model for intubation teaching is used normally, the chest cavity set inside the simulation model body accommodates an adapted lung model, which is used to simulate the human lung structure. The head model connected to the front end is used to simulate the human head structure. A pseudo-tracheal structure is set inside it, and the two ends of the structure are respectively connected between the inside of the lung model and the face of the head model. The real tracheal intubation operation can be simulated through the mouth, and it can be connected to a ventilator for use, realizing the combined use of the heart and lungs of ECMO and the ventilator, enhancing authenticity and interactivity, and thus being close to the real clinical experience, thereby improving the teaching effect.

[0012] Preferably, the simulation model body is provided with a connection hole, which is arranged at the head and neck of the simulation model body;

[0013] The simulation model body is also equipped with an intravenous infusion device, which includes

[0014] an intravenous infusion chamber, fixed in the chest cavity and used for storing infusion;

[0015] One end of the intravenous infusion tube is connected to the intravenous infusion chamber, and the other end is fixed in the connecting hole.

[0016] Through the above technical solution, a connection hole is opened on the head and neck of the simulation model body, and one end of the intravenous infusion tube is placed in the connection hole. The end of the tube has a simulated skin structure, which is convenient for intravenous infusion to simulate the catheter path during real intravenous infusion. The other end is connected to the intravenous infusion chamber, which is fixed in the chest cavity and serves as a liquid storage space for storing simulated infusion liquid, expanding the simulation operation of intravenous infusion, further deepening the understanding and mastery of comprehensive clinical skills, and thus improving the actual teaching effect.

[0017] Preferably, the simulation model body is provided with a plurality of mounting positions and a plurality of skin-like blocks, the skin-like blocks are installed in the corresponding mounting positions, and each of the skin-like blocks is provided with a channel;

[0018] An in-vivo circulation device is installed in the main body of the simulation model, and the in-vivo circulation device includes a circulation pump;

[0019] The simulation model body is provided with a control switch, which acts on the circulation pump to control the circulation pump to switch and adjust between multiple intensities.

[0020] Through the above technical solution, skin-like blocks are set in the installation positions at different locations. The skin-like blocks are puncturable parts. During teaching, ultrasonic exploration, puncture or other designs can be performed at the skin-like blocks. Other skin-like blocks can be set according to actual needs to realize teaching simulation of different parts, so that the model teaching is closer to clinical practice and better meets clinical needs.

[0021] The in-vivo circulation device simulates the blood circulation in the human body and drives the simulated blood to circulate inside the simulation model. The channels opened by the skin-like blocks are used for the insertion of simulated artificial blood vessels. The artificial blood vessels can carry liquid flow. The circulation pump is controlled by operating the control switch to switch its operating speed and intensity, simulating the application scenarios of ECMO in real clinical practice. The in-vivo circulation status under different physiological states (such as normal circulation, accelerated circulation, decelerated circulation, etc.) improves flexibility, further enables the teaching content to go deep into the complexity and variability of the internal circulation, and further improves the teaching effect.

[0022] Preferably, a mounting groove is provided in the chest cavity, and the in vivo circulation device further comprises a water tank fixed in the mounting groove;

[0023] A battery is placed in the simulation model body and connected to the circulation pump via a wire;

[0024] The liquid outlet of the circulation pump is connected to the liquid return port of the water tank through an artificial blood vessel arranged in a channel of the corresponding skin-like block;

[0025] The battery supplies power to enable the circulation pump to extract the liquid in the water tank and then transport it back to the water tank through the artificial blood vessel.

[0026] Through the above technical solution, the water tank is fixed in a fixed groove and equipped with a battery as a power source. The wires between the battery and the circulation pump are electrically connected. The electricity drives the circulation pump to draw out the liquid in the water tank and transport it to the artificial blood vessel. After flowing through the corresponding skin-like block, it returns to the water tank through the artificial blood vessel, thereby realizing a complete internal circulation path, simulating the real circulation process in the human body and improving the simulation degree.

[0027] Preferably, a limiting plate is provided in the installation groove, which protrudes and is fixed to the bottom of the installation groove to position the water tank.

[0028] Through the above technical solution, an appropriate gap is created between the water tank and the lung model through the limiting plate, leaving a larger space in the chest cavity for the normal installation of the lung model to avoid mutual interference. The limiting plate ensures that the water tank is quickly fixed in its proper position during the installation process, enhances the positioning effect, and improves the fixing stability.

[0029] Preferably, the simulation model body has a pressing module for use in pressing.

[0030] Through the above technical solution, the compression module is set above the lung model, has a certain deformation ability, and can be used for compression, simulating the real compression process, performing ECMO operation while cardiopulmonary resuscitation, and restoring ECPR (CPR under ECMO maintenance, a technical term) in real cardiac arrest situations, further improving the authenticity of the clinical environment, and thus improving the effectiveness of teaching use.

[0031] Preferably, the skin-like block includes an upper skin-like block and a lower skin-like block, and the lower skin-like block is provided with a groove;

[0032] When the upper skin-like block and the lower skin-like block are spliced together, the grooves correspondingly form the channels.

[0033] Through the above technical solution, a groove is opened on the upper end surface of the lower skin-like block, and the upper skin-like block is spliced on top of the lower skin-like block to form a complete skin-like block. The groove corresponds to a channel, and the assembled skin-like block is then installed in the installation position, avoiding the complexity of directly opening a hole on a single component. The skin-like block is easy to separate and replace, which improves the maintenance efficiency of the model.

[0034] Preferably, a delivery pipeline is provided in the simulation model body, one end of which is connected to the water tank and the other end is connected to the channel of the skin-like block located at the leg of the simulation model body.

[0035] Through the above technical solution, the delivery pipeline is built into the simulation model body, which acts on a part of the body's circulation. Under the action of the pump, the liquid in the water tank will pass through the artificial blood vessels in the delivery pipeline and be delivered to other parts inside the model to realize the simulated arteries and veins of the legs of the associated simulation model body.

[0036] Preferably, the upper end surface of the water tank is recessed with a fixing groove, and the skin-like block is installed in the fixing groove;

[0037] The side wall of the fixing groove passes through the vertical side wall of the water tank, and a water tank connector is provided on the opposite side thereof to conduct to the inside of the water tank;

[0038] The water tank joint is arranged correspondingly to the delivery pipeline;

[0039] The intracorporeal circulation device has an abdominal aorta groove and an inferior vena cava groove, so that the abdominal aorta and the inferior vena cava are both located between the skin-like blocks that fix the bottom of the groove.

[0040] Through the above technical solution, a fixing groove is added to the upper end surface of the water tank, and the abdominal aorta groove and inferior vena cava groove are opened at the bottom of the fixing groove. Artificial blood vessels connected between the delivery pipeline and the water tank joint are passed through the two grooves. Skin-like blocks are cleverly embedded in the fixing groove. Ultrasound is generally used to explore the inferior vena cava / abdominal aorta to ensure that the pipeline / guide wire is in the artificial blood vessel.

[0041] Preferably, a drainage portion is provided at the bottom of the simulation model body, which has a drainage groove and a drainage hole for a drainage pipe to pass through.

[0042] The water tank is provided with a drainage joint, which is connected to the bottom of the water tank. After the water tank is installed on the limit plate, the drainage joint is located in the drainage groove, and its drainage port faces the drainage hole for access to the drainage pipe.

[0043] Through the above technical solution, a drainage groove is opened in the drainage part at the bottom. When the water tank is installed in the installation groove, the drainage joint at its bottom is located in the drainage groove, and the port of the drainage joint faces the drainage hole. After the drain pipe is passed through the drainage hole, it can be connected to the drainage joint. The liquid in the water tank is quickly discharged through the drainage hole, avoiding the tedious disassembly and dumping process, simplifying the operation to improve efficiency, and optimizing the user experience of the model.

[0044] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0045] 1. This technical solution adds a head model to the main body of the simulation model to simulate the human head structure, adds a lung model to the chest cavity to simulate the human lung structure, connects the two ends of the simulated trachea structure between the lung model and the face of the head model, and forms an oral cavity on the face wall to simulate the real tracheal intubation operation. It is connected to a ventilator for use, realizing the combined use of ECMO and the heart and lungs of the ventilator, thus being close to the real clinical experience, thereby improving the teaching effect;

[0046] 2. This technical solution simulates real intravenous infusion by installing an intravenous infusion device in the simulation model body, including an intravenous infusion chamber and an intravenous infusion tube. One end of the intravenous infusion tube is connected to the intravenous infusion chamber, and the other end is fixed in the connection hole. The intravenous infusion chamber stores liquid, thereby improving the actual teaching effect.

[0047] 3. This technical solution provides a compression module on the main body of the simulation model for compression, simulating the compression process, performing ECMO operation while performing cardiopulmonary resuscitation, restoring the ECPR under real cardiac arrest conditions, further improving the authenticity of the clinical environment, and thus improving the effectiveness of teaching.

DETAILED DESCRIPTION

[0054] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0055] Example:

[0056] See also Figure 1 and Figure 3 An ECMO teaching model for intubation teaching includes a simulation model body 1, which is designed to imitate the size and shape of a real human body, and a chest cavity 2 is opened inside the simulation model body 1. The chest cavity is designed to correspond to the position of the human chest cavity and is relatively located in the front of the simulation model body 1.

[0057] It also includes a head model 4, which is designed to imitate the size and shape of a real human head and is connected to the front end of the simulation model body 1. The chest cavity 2 has an opening facing the head model 4, so that the head model 4 is installed and received at the opening.

[0058] The simulation model body 1 is provided with a connection hole 7, which is opened at the head and neck part of the simulation model body 1. One end of the connection hole 7 passes through the chest cavity 2. An intravenous infusion device 8 is also installed in the simulation model body 1, which is hidden and fixed in the chest cavity 2. The intravenous infusion device 8 includes an intravenous infusion chamber 81 and an intravenous infusion tube 82. The shape of the intravenous infusion chamber 81 is bag-shaped, sac-shaped or box-shaped. In this embodiment, it is preferably box-shaped, which is used for liquid storage. One end of the intravenous infusion tube 82 is connected to the inside of the intravenous infusion chamber 81, and the other end is placed in the connection hole 7 and fixed. The end portion arranged in the connection hole 7 has a skin-like structure, which is used to simulate intravenous infusion. The input liquid is introduced into the intravenous infusion chamber 81 along the intravenous infusion tube 82.

[0059] See also Figure 3 and Figure 5 , also includes a lung model 3 and a pseudo-trachea structure 5. The lung model 3 simulates the real human lung structure. It includes two parts corresponding to the left lung and the right lung respectively. Both are fixed in the chest cavity 2 and arranged close to the head model 4. The pseudo-trachea structure 5 is in the shape of a curved tube, one end of which is connected to the lung model 3 and the other end is correspondingly arranged on the head model 4. An oral cavity 6 is formed on the face of the head model 4. The oral cavity 6 remains open and can be used for real tracheal intubation and connection to a ventilator, realizing the combined use of ECMO and the heart and lungs of the ventilator, which is closer to clinical experience.

[0060] The simulation model body 1 has a pressing module 16, which has a certain deformation ability for pressing. The user can simulate the pressing process, apply pressing force on the pressing module 16, simulate cardiopulmonary resuscitation, and perform ECMO operation at the same time as cardiopulmonary resuscitation, restoring the ECPR (CPR under ECMO maintenance, which is a technical term and will not be elaborated here) in a real cardiac arrest situation.

[0061] See also Figure 4 and Figure 5 The simulation model body 1 is provided with several mounting positions 9 and several skin-like blocks 10. The skin-like blocks 10 are puncturable parts. During teaching, ultrasonic exploration, puncture or other designs can be performed at the skin-like blocks 10. The number of the skin-like blocks 10 is the same as the mounting positions 9. In this embodiment, there are four mounting positions 9. Each skin-like block 10 can be embedded in the corresponding mounting position 9 and fixed one by one. The four skin-like blocks 10 can be classified into neck skin-like blocks 10, abdomen skin-like blocks 10 and two leg skin-like blocks 10 according to actual use.

[0062] Each skin-like block 10 is provided with a channel 11, and each channel 11 is designed according to the human body layout. The channel 11 in this embodiment is used to bury a number of artificial blood vessels, which use rubber tubes or other soft tubes. The artificial blood vessels provide simulated blood circulation. The specific channel 11 is formed in such a way that each skin-like block 10 includes an upper skin-like block 101 and a lower skin-like block 102. The lower skin-like block 102 is provided with a number of grooves 17. The upper skin-like block 101 is correspondingly covered on the lower skin-like block 102, so that the channel 11 is formed by splicing. The upper skin-like block 101 and the lower skin-like block 102 tightly wrap the artificial blood vessels.

[0063] An in-vivo circulation device 12 is also installed in the simulation model body 1, which includes a circulation pump 121, a water tank 122 and a battery 123. A mounting groove 14 is opened in the chest cavity 2, which is located at the bottom of the chest cavity 2. A limiting plate 15 is provided in the mounting groove 14, and the limiting plate 15 protrudes and is fixed at the bottom of the mounting groove 14. The water tank 122 is fixed in the limiting plate 15 to achieve positioning in the mounting groove 14. The water tank 122 stores liquid for providing simulated blood in the in-vivo circulation.

[0064] A fixing groove 20 is recessed on the upper end surface of the water tank 122. The side wall of the fixing groove 20 passes through the vertical side wall of the water tank 122. A water tank 122 connector that connects to the inside of the water tank 122 is provided on the opposite surface. The connector can be connected to the port of the delivery pipeline 19. The in vivo circulation device 12 has an abdominal aorta groove 22 and an inferior vena cava groove 23. A skin-like block 10 is installed in the fixing groove 20, so that the two grooves simulate the abdominal aorta and inferior vena cava respectively. The artificial blood vessels arranged therein are tightly wrapped by the skin-like block 10, so that the large blood vessels located in the abdomen (abdominal aorta and inferior vena cava) can meet the requirements of ultrasonic quality control / ultrasound detection (because ultrasound cannot penetrate the air, but other materials can penetrate it). Ultrasound quality control can also be called ultrasound detection.

[0065] Existing models do not have the function of ultrasound exploration teaching. The skin-like block 10 has a high ultrasound transmittance and can better ensure the teaching effect.

[0066] The battery 123 is used to provide electrical energy and is connected to the circulation pump 121 through a wire. When the circulation pump 121 is working, the liquid in the water tank 122 is extracted and transported along the artificial blood vessel. After flowing through each corresponding skin-like block 10, it returns to the water tank 122 through the artificial blood vessel, simulating the entire internal circulation process.

[0067] The simulation model body 1 is provided with a control switch 13, which is electrically connected to the circulating pump 121 and acts on the circulating pump 121 to control the circulating pump 121 to switch and adjust between multiple intensities. In this embodiment, the adjustment has three gears, and the three gears correspond to three intensities of the circulating pump 121. Among them, the first gear simulates low cardiac output (1L / min), the second gear simulates normal cardiac output (3L / min), and the third gear simulates high cardiac output (5L / min), thereby simulating multiple application scenarios of ECMO in real clinical practice and further expanding the usage experience.

[0068] A delivery pipeline 19 is provided in the simulation model body 1, which has a bifurcated structure. The port at one end is connected to the water tank 122, and the differentiated ports at the other end are respectively connected to the channels 11 of the skin-like blocks 10 located on the left and right legs. The interior of the delivery pipeline 19 is generally used for artificial blood vessels to pass through, simulating the blood circulation in the abdominal cavity.

[0069] See also Figure 2 A drainage portion 24 is provided at the bottom of the simulation model body 1, and its position corresponds to the position of the water tank 122. The drainage portion 24 is penetrated by a drainage groove 25, and the water tank 122 is provided with a drainage joint 27, which is connected to the bottom of the water tank 122 and is located just in the drainage groove 25. The drainage portion 24 is also provided with a drainage hole 26, which is provided on the side wall of the drainage portion 24. When the drainage joint 27 is in use, its interface end is set toward the drainage hole 26. After the drainage joint 27 is connected to the water pipe, the water pipe can pass through the drainage hole 26. By installing a valve on the drainage pipe to control the conduction or closing of the drainage pipe, the liquid in the water tank 122 can be discharged.

[0070] The specific working process of this program is as follows:

[0071] This technical solution sets a chest cavity 2 in the simulation model body 1, which contains a lung model 3 for simulating the human lung structure. The front end of the simulation model body 1 is connected to a head model 4 to simulate the human head structure. A pseudo-tracheal structure 5 is set inside it, and the two ends of the structure are respectively connected between the inside of the lung model 3 and the face of the head model 4. Through the mouth 6, it can simulate the real tracheal intubation operation and be connected to the ventilator for use, realizing the combined use of ECMO and the heart and lungs of the ventilator, enhancing authenticity and interactivity, and thus being close to the real clinical experience, thereby improving the teaching effect.
