Description

Technical Field

[0001] This invention relates to the field of medical education, specifically to a wearable blood purification simulation training suit. Background Technology

[0002] Currently, there are specialized mannequins available on the market for research and training in blood purification, as detailed in Chinese Patent CN211087693U. These mannequins, used in conjunction with external blood purification equipment, enable a comprehensive understanding and mastery of the entire blood purification process. They simulate the human circulatory system by forming a pathway with a liquid-containing capsule, simulated arterial tubing, an automatic constant-pressure micro-pump, and simulated venous tubing. The mannequins are equipped with hemodialysis catheter interfaces for the right subclavian vein, right internal jugular vein, and right femoral vein, all fitted with external end caps for connecting to external blood purification equipment. Furthermore, they feature an arteriovenous anastomosis fistula for use with the cephalic vein and radial artery tubing, with the cephalic vein tubing connected to the radial artery tubing via the arteriovenous anastomosis fistula.

[0003] The aforementioned blood purification mannequins still have certain shortcomings in training, specifically: First, traditional blood purification mannequins, using a demonstration method, lack realism. The mannequin's shape and style are fixed, resulting in a lack of realism during demonstrations, displays, and simulations, thus reducing the effectiveness of the training. Second, traditional blood purification mannequins require fabrication after molding. The rigid structure, simulating the actual height of the human body, is unsuitable for transportation and transfer, and is also costly to manufacture, requiring expensive materials and occupying significant space during transport, increasing costs. Third, traditional blood purification mannequins require a fixed standing posture during use, which lacks stability during display. A lying posture further reduces the demonstration effect. Additionally, traditional blood purification mannequins have fixed installations of the hemodialysis equipment's connecting tubing, failing to achieve the purpose of puncture and cannulation training. Furthermore, the tubing connections are not replaceable, have a short lifespan, and become unusable after partial damage, resulting in resource waste.

[0004] In summary, a wearable blood purification simulation training suit is provided that offers vivid display effects, high realism during use, and can be used in a human wearable mode. It enables demonstrations, simulations, and auxiliary training after being worn by real people. It can be used for hemodialysis cannulation training and can also be connected to external equipment to demonstrate the hemodialysis process. It is easy to transfer and transport, has a long service life, and allows for partial replacement and maintenance. It has broad market prospects. Summary of the Invention

[0008] The circulating water bladder is connected to the inlet of a three-way one-way outlet valve via a main outlet pipe equipped with an automatic constant pressure micro water pump. One outlet of the three-way one-way outlet valve is connected to the internal jugular vein bladder via an internal carotid artery prosthetic vessel. The internal jugular vein bladder is connected to the subclavian vein bladder via the internal jugular vein prosthetic vessel. The subclavian vein bladder is connected to one inlet of the three-way one-way inlet valve via the subclavian vein prosthetic vessel.

The cephalic vein bladder is connected to the femoral vein bladder via the cephalic vein prosthetic vessel. The femoral vein bladder is connected to the other inlet of the three-way one-way inlet valve via the femoral vein prosthetic vessel.

[0009] The top of the one-piece suit is a neck extension. The internal jugular vein sac is fixedly installed at this neck extension position by a sewing connector. The subclavian vein sac is set at the corresponding position of the right clavicle on the front side of the one-piece suit by a sewing connector. The femoral vein sac is set at the corresponding position of the right groin area on the front side of the one-piece suit by a sewing connector. The radial artery sac and cephalic vein sac are respectively set at the corresponding positions above the stoma in the forearm of the one-piece suit by sewing connectors. An automatic constant pressure micro water pump is set at the corresponding position of the heart on the front side of the one-piece suit.

[0010] The aforementioned one-piece wearable garment is made of needle-proof insulating material. A control box is installed on the outside of the automatic constant pressure micro water pump through a sewn connector. The control box is equipped with a control switch that is electrically connected to the automatic constant pressure micro water pump. The control switch is electrically connected to the external power cord socket.

[0011] The circulating water bladder has a water injection pipe with a one-way water inlet valve at the top and a drain pipe with an opening and closing valve at the bottom.

[0015] The present invention has the following positive effects: 1. This product uses a wearable structure to carry out blood purification training. When in use, it can be worn by real people for demonstration, display and assistance in simulating training. The overall realism is high. Using real people to carry out the operation makes the effect more vivid. Users can more easily improve the visual sensory effect during the simulation training process, thus improving the effectiveness of the training operation.

[0016] 2. This product adopts a one-piece wearable structure, which can be folded for storage and unfolded for simulation training. Due to the use of a soft structure, it facilitates transportation and transfer operations, does not take up too much space, increases the overall carrying capacity, and reduces transportation costs.

[0017] 3. During the use of this product, it can be displayed, demonstrated, and trained independently using a one-piece wearable suit. At the same time, it can also be protected by an external one-piece protective suit. It flexibly adopts different display methods for use in multiple scenarios. More importantly, this product provides two methods for simulated training: puncture simulation skin layer or double-lumen catheter. It can be used for puncture training and can also be directly connected to external equipment for display and demonstration. It is versatile, efficient, and convenient to operate.

[0018] 4. This invention highly simulates the human arteriovenous circulation system, providing a more realistic demonstration effect. The tubing is connected individually, allowing for local replacement of damaged components. Two three-way check valves control the entire tubing system to achieve fluid circulation. Multiple sacs corresponding to puncture sites are included for puncture training and external tubing connection.

[0026] 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.

[0027] In the following description of the invention, it should be noted that the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. The term "connection" simply indicates a connection between devices and has no special meaning.

[0028] like Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, a wearable blood purification simulation training suit includes a one-piece suit 1 with a wearing opening 29 on the back. A circulating water bladder 2 is fixedly installed on the front of the one-piece suit 1. The circulating water bladder 2 is connected to the inlet end of a three-way one-way outlet valve 4 via an automatic constant-pressure micro-pump 27. The two one-way outlet ends of the three-way one-way outlet valve 4 are respectively connected to the internal jugular vein sac 17 and the radial artery sac 7 via pipes. The internal jugular vein sac 17 is connected to the subclavian vein sac 15 via a pipe. The radial artery sac 7 is connected to the cephalic vein sac 9 via a venous anastomosis fistula pipe 8. The femoral vein sac 9 is connected to the femoral vein sac 11 via a conduit. The femoral vein sac 11 and the subclavian vein sac 15 are respectively connected to the two inlet ends of the three-way one-way inlet valve 13 via conduits. The outlet end of the three-way one-way inlet valve 13 is connected to the circulating water sac 2 via a conduit. A femoral vein puncture simulation skin 24 or a femoral vein double-lumen catheter 42 is provided on the outside of the femoral vein sac 11. A subclavian vein puncture simulation skin 25 or a subclavian vein double-lumen catheter 41 is provided on the outside of the subclavian vein sac 15. An internal jugular vein puncture simulation skin 26 or an internal jugular vein double-lumen catheter 29 is provided on the outside of the internal jugular vein sac 17.

[0029] In use, the onesie 1 has a wearing opening 29 at the back, located at the rear of the upper part of the onesie 1, facilitating the user's bottom-up dressing without affecting the display effect of the front of the upper part. The lower part of the onesie 1 is a long trouser or shorts structure, which can be directly put on the outside of the legs. The upper part of the onesie 1 covers the chest and abdomen, and also covers the upper limbs. Therefore, in use, the human body can wear it directly. After wearing, the onesie 1 is a one-piece structure that fits on the outside of the human body. It can deform in coordination with the movement of the human body and limbs, enabling real-life wearing demonstrations, presentations, or simulated training of puncture operations. The overall realism is high. Compared with traditional mannequin displays, the simulation training effect of this invention is more obvious. Users can more intuitively observe and conduct simulation training, more realistically simulating later work scenarios, thereby improving the simulation training effect of this product.

[0030] This product utilizes a circulating water bladder 2 in conjunction with the internal jugular vein bladder 17, radial artery bladder 7, cephalic vein bladder 9, femoral vein bladder 11, and subclavian vein bladder 15. This provides a hemodialysis reference position corresponding to the actual human body location for external tubing connections and puncture training, achieving a highly realistic component configuration. Simultaneously, a three-way one-way discharge valve 4 and a three-way one-way inlet valve 13 facilitate the coordinated circulation between the bladders, ensuring that fluid circulates from the circulating water bladder 2 towards the radial artery bladder 7, cephalic vein bladder 9, and femoral vein bladder 11, ultimately returning to the circulating water bladder 2. It also ensures that fluid flows from the circulating water bladder 2 towards the cephalic vein bladder 9 and subclavian vein bladder 15 back to the circulating water bladder 2. The overall design simulates the human circulatory system with high realism, resulting in a more lifelike demonstration.

[0031] This product employs two simulation training modes. The first involves installing a simulated puncture layer on each corresponding capsule. During the puncture procedure, the puncture tubing is inserted into the capsule through this simulated layer for hemodialysis puncture training. The second mode directly connects the double-lumen catheter to the corresponding capsule and seals it with a plug. In use, the plug is opened, and the double-lumen catheter is connected to the external hemodialysis equipment tubing, achieving a realistic hemodialysis training operation. Demonstrations are conducted using real people, resulting in a more realistic experience.

[0032] The one-piece wearable garment 1 is fitted with a one-piece external protective garment 30 on its outer side. The rear side of the one-piece external protective garment 30 is provided with a protective garment wearing opening 31 that matches the wearing opening 29. The protective garment wearing opening 31 is provided with a matching hook layer and a hair layer. The one-piece external protective garment 30 corresponding to the internal jugular vein sac 17 is provided with an internal jugular vein puncture training reference hole 35 or an internal jugular vein double-lumen catheter penetration hole 38. The one-piece external protective garment 30 corresponding to the subclavian vein sac 15 is provided with a subclavian vein puncture training reference hole 36 or a subclavian vein double-lumen catheter penetration hole 39. The one-piece external protective garment 30 corresponding to the femoral vein sac 11 is provided with a femoral vein puncture training reference hole 37 or a femoral vein double-lumen catheter penetration hole 40.

[0033] To extend the product's lifespan and provide multiple simulation training modes, a one-piece external protective suit 30 is fitted over the one-piece wearable suit 1. When in use, the one-piece external protective suit 30 covers the tubing and the capsule, providing protection and extending the product's lifespan. Simultaneously, it exposes the puncture simulation skin layer and double-lumen catheter positions on the capsule, protecting the tubing components while clearly displaying the reference puncture position. This prevents damage to the capsule and tubing due to misoperation during use, significantly improving the product's lifespan. Furthermore, it offers multiple simulation training modes, providing diverse functions and enhancing the simulation effect.

[0034] The circulating water bladder 2 is connected to the inlet end of the three-way one-way outlet valve 4 via the main outlet pipe 5 equipped with an automatic constant pressure micro water pump 27. One outlet end of the three-way one-way outlet valve 4 is connected to the internal jugular vein bladder 17 via the internal carotid artery artificial blood vessel 18. The internal jugular vein bladder 17 is connected to the subclavian vein bladder 15 via the internal jugular vein artificial blood vessel 16. The subclavian vein bladder 15 is connected to one inlet end of the three-way one-way inlet valve 13 via the subclavian vein artificial blood vessel 14. The other outlet end of the three-way one-way outlet valve 4 is connected to the radial artery bladder 7 via the radial artery artificial blood vessel 6. The cephalic vein bladder 9 is connected to the femoral vein bladder 11 via the cephalic vein artificial blood vessel 10. The femoral vein bladder 11 is connected to the other inlet end of the three-way one-way inlet valve 13 via the femoral vein artificial blood vessel 12.

[0035] This product simulates the real human circulatory system and uses multiple artificial blood vessels for simulated connection. Both ends of each artificial conduit are connected through movable interfaces, allowing for replacement if a single artificial blood vessel is damaged. The artificial blood vessels themselves can be used for multiple punctures, and each capsule can also be replaced if a single one is damaged, saving costs, reducing maintenance and repair costs, conserving resources, and increasing service life.

[0036] The top of the onesiere-like garment 1 is a neck extension. The internal jugular vein sac 17 is fixedly installed at the neck extension position through a sewing connector 28. The subclavian vein sac 15 is set at the corresponding position of the right clavicle on the front side of the onesiere-like garment 1 through a sewing connector 28. The femoral vein sac 11 is set at the corresponding position of the right groin area on the front side of the onesiere-like garment 1 through a sewing connector 28. The radial artery sac 7 and the cephalic vein sac 9 are respectively set at the corresponding positions above the stoma in the forearm of the onesiere-like garment 1 through a sewing connector 28. The automatic constant pressure micro water pump 27 is set at the corresponding position of the heart on the front side of the onesiere-like garment 1.

[0037] To improve the stability of this product during operation, each capsule and key component is sewn together using a sewing connector 28. All key components and even tubing are fixed in a fixed manner. After being worn by a person, the one-piece suit 1 can deform and adjust with the body parts, and can also be sewn together with the outer one-piece external protection 30 to ensure the corresponding setting of the puncture training reference hole and the double-lumen catheter protrusion hole, thus improving the stability of the product during use.

[0038] The one-piece wearable garment 1 is made of needle-puncture-resistant insulating material. A control box 3 is installed on the outside of the automatic constant-pressure micro water pump 27 via a sewn connector 28. The control box 3 is equipped with a control switch 22 electrically connected to the automatic constant-pressure micro water pump 27, and the control switch 22 is electrically connected to an external power cord socket 23. The top of the circulating water bladder 2 is equipped with a water injection pipe 19 with a one-way water inlet valve, and the bottom of the circulating water bladder 2 is equipped with a drain pipe 21 with an openable / closeable valve. The circulating water bladder 2 is positioned on the front abdomen of the one-piece wearable garment 1 via the sewn connector 28.

[0039] When using this product, since it can be worn by real people, the safety of real people wearing it needs to be considered. The bodysuit is made of needle-proof insulating material, which can prevent needle-puncture injuries and avoid electrical safety threats. The overall safety factor is high. The control components simulate the position of the human heart, which is highly realistic, technologically advanced, and has obvious simulation effect.

[0040] The one-piece external protective suit 30 has a control box 3 on its front side, which is fitted onto the corresponding position outside the automatic constant pressure micro water pump 27. The control box 3 is equipped with an electrically connected control switch 22, which is electrically connected to an external power cord socket 23. The front side of the one-piece external protective suit 30 also has a water inlet pipe 31 and a drain outlet 32. The water inlet pipe 31 is connected to the top of the circulating water bladder 2 via a pipe, and the drain outlet 32 ​​is connected to the bottom of the circulating water bladder 2 via a pipe. Both the outer ends of the water inlet pipe 31 and the drain outlet 32 ​​are fitted with plugs. The forearm of the one-piece external protective suit 30 has a radial artery corresponding reference hole 33 and a cephalic vein corresponding reference hole 34 that correspond to the radial artery bladder 7 and the cephalic vein bladder 9, respectively.

[0041] The circulating water bladder 2 can perform water injection and sewage discharge operations, improving the controllability of the product during operation.

During operation, a real person wears the one-piece wearable suit 1, or puts the one-piece wearable suit on a regular mannequin shell for simulation training. In this embodiment, the femoral vein puncture simulation skin layer 24, the subclavian vein puncture simulation skin layer 25, the internal jugular vein puncture simulation skin layer 26, the radial artery sac 7, and the cephalic vein sac 9 directly perform the puncture training operation of the hemodialysis catheter. After the hemodialysis catheter is connected to the external hemodialysis equipment tubing, the simulation training operation can be carried out. The entire process is demonstrated by real people wearing the suit, and the effect is realistic.

[0043] Example 2: As Figure 2 , 3 As shown in Figure 4, this embodiment uses only the one-piece wearable suit 1 for simulation training, and employs a double-lumen catheter setup for simulation training.

In this embodiment, the femoral vein double-lumen catheter 42, subclavian vein double-lumen catheter 41, and internal jugular vein double-lumen catheter 29 can be directly connected to the external hemodialysis equipment tubing for simulation training. The radial artery balloon 7 and cephalic vein balloon 9 are used directly for hemodialysis catheter puncture training. After puncture, the hemodialysis catheter is connected to the external hemodialysis equipment tubing for simulation training. The entire process is demonstrated using real people wearing the suit, resulting in a realistic effect.

[0044] Example 3: As Figure 1 , 3As shown in Figures 4, 5, and 7, this embodiment uses a one-piece external protective suit 30 placed on the outside of the one-piece wearable suit 1 for simulation training. Simulation training is conducted by setting up a puncture simulation skin layer. During operation, a real person wears the one-piece wearable suit 1 and the one-piece external protective suit 30, or places the one-piece wearable suit and the one-piece external protective suit onto a regular mannequin shell for simulation training. In this embodiment, the reference hole 35 for venous puncture training corresponds to the position of the internal jugular vein puncture simulation skin layer 26, and the reference hole 36 for subclavian vein puncture training corresponds to the subclavian vein puncture simulation skin layer 25.

When this embodiment is used, the femoral vein puncture simulation skin 24, the subclavian vein puncture simulation skin 25, the internal jugular vein puncture simulation skin 26, the radial artery sac 7, and the cephalic vein sac 9 directly carry out the puncture training operation of the hemodialysis catheter. After the hemodialysis catheter is connected to the external hemodialysis equipment tubing, the simulation training operation can be carried out. The whole process is demonstrated by real people wearing the device, and the effect is realistic.

[0045] Example 4: Figure 2 , 3 As shown in Figures 4, 6, and 7, this embodiment uses a one-piece external protective suit 30 placed on the outside of the one-piece wearable suit 1 for simulation training. A double-lumen catheter is used for simulation training. During operation, the real person wears the one-piece wearable suit 1 and the one-piece external protective suit 30, or places the one-piece wearable suit and the one-piece external protective suit onto a regular mannequin shell for simulation training. In this embodiment, the internal jugular vein double-lumen catheter perforation hole 38 corresponds to the installation position of the internal jugular vein double-lumen catheter 29, the subclavian vein double-lumen catheter perforation hole 39 corresponds to the installation position of the subclavian vein double-lumen catheter 41, and the femoral vein double-lumen catheter perforation hole 40 corresponds to the installation position of the femoral vein double-lumen catheter 42. The radial artery corresponding reference hole 33 and the cephalic vein corresponding reference hole 34 correspond to the positions of the radial artery sac 7 and the cephalic vein sac 9, respectively.
