[0001] The present invention relates to the technical field of online training, and in particular to a 3D online training system for a hemodialysis machine. Background Art

[0002] The development of hemodialysis machines is becoming more and more mature, and the humanized design of operation is also popular. Hemodialysis machines are different from other commonly used electronic instruments. During the dialysis process, any problem in each unit will cause downtime, affecting the normal treatment. Therefore, to ensure the normal operation of the machine, it is very important to carry out strict and meticulous maintenance and regular inspection and repair management.

[0003] At present, the maintenance of hemodialysis machines often requires professional operation of maintenance personnel, and the professional skills of maintenance personnel directly affect whether the hemodialysis machine can operate normally. Therefore, it is very important to train maintenance personnel on hemodialysis machines. At present, the training related to the maintenance, fault diagnosis and maintenance of hemodialysis machines is still mainly based on text materials and on-site training, although there are also mobile phone or mobile terminal applications to supplement the realization of remote technical support or remote teaching and training and other online interactions and exchanges.

[0004] However, due to the uneven levels of on-site maintenance personnel or trainees, they often cannot correctly understand the true meaning of technical support or explainers, resulting in poor communication of some information, which often leads to unsatisfactory results for troubleshooting and training. At the same time, due to the impact of the epidemic, the flow and gathering of personnel will be greatly affected in the future. In this environment, it is not suitable to organize maintenance training and teaching activities in fixed places with many participants. Therefore, there are great limitations for the training of hemodialysis machines.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The present application provides a 3D online training system for a hemodialysis machine, which can realistically reproduce the positions of various modules and accessories inside the device, simulate the online training or maintenance, disassembly, and assembly processes of a real machine, and simultaneously display the functions, structures, common or typical faults, and solutions to some difficult faults of each module or accessory, so that users can quickly understand the principles, internal structures, positions, maintenance processes, etc. of the device in an immersive way.

[0030] Specifically:

[0031] A 3D online training system for a hemodialysis machine, comprising:

[0032] The database is used to store the structure, function and common failure points of each module or accessory of the hemodialysis machine, as well as the disassembly, restoration and maintenance process of each module and form a database.

[0033] The technical support of the database is based on the original machine manual, maintenance manual, technical manual, exploded diagram of accessories, photos and videos of expert disassembly and assembly process. Specifically, the formation of the database includes combining the original machine technical data, and having technical experts with many years of maintenance and practical experience personally disassemble the real machine on site, take photos and videos, associate the obtained information with various fault phenomena, and enter them into the database in different categories. At the same time, the structure, function, internal components and corresponding common fault points of the disassembled modules, i.e. accessories, are entered into the database to form an expert-level database, which is a good supplement for maintenance, scientific research, training, etc.

[0034] In addition, during the use of the database, as technology is updated, new technical information, technical operation photos and videos, etc. can be continuously entered to enrich and improve the database to keep up with technological changes.

[0035] Access to the database is based on the central control unit.

[0036] The central control unit is used to control each module or accessory of the hemodialysis machine 3D online training system, access the database, and receive and process data feedback from the outside.

[0037] The central control component is electrically connected to the VR simulation component.

[0038] The VR simulation component is used to receive instructions from the central control unit, generate multiple VR virtual training scenes based on the database, and reproduce the disassembly and restoration process of the hemodialysis machine in real time with a 3D perspective. Users complete the corresponding training content in the virtual training scene reproduced by the VR simulation component.

[0039] It should be noted that VR technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It is a system simulation of multi-source information fusion, interactive three-dimensional dynamic vision and entity behavior, and can immerse users in the virtual environment to simulate a series of corresponding processes in the environment. In this application, VR technology is combined with the 3D online training system for hemodialysis machines. It is not an improvement on VR technology, but a combination of a hemodialysis machine simulation unit to effectively realize simulation training for hemodialysis machine maintenance.

[0040] VR technology can fully display the surface and structure of each module or accessory, and provide a WYSIWYG scenario-based guide for users to quickly understand the internal conditions of the equipment and handle various related faults. When users operate the 3D online training system, it is like opening the inside of a real machine, which is helpful for fault diagnosis and repair.

[0041] In this way, it can not only serve as a query and reference for experts or engineers with better technical skills, but also serve as a good reference and reference for maintenance personnel who come into contact with the machine for the first time on site. It is suitable for online training and self-study.

[0042] The VR virtual training scene displays content including the name, function, composition and internal structure of each module and accessory, corresponding serial number and article number, common failure points, analysis of related failures, as well as solutions to common and difficult failures.

[0043] Each module and accessory shows its corresponding function, structure and common failure points.

[0044] Among them, the modules in the system include internal pressure test module, flushing gun module, body shell, multi-functional degassing module, dry powder module, balance chamber module, drainage module, bypass module, head module, module rack, water distribution module, etc.

[0045] Taking the body shell and head module as an example of the accessories inside, the body shell includes lower module cover 01, lower module cover 02, lower module cover 03, water outlet connector, main control back cover, baffle, head back cover, disinfectant connector, water inlet connector; the head module includes 631 signal board, 632 signal board, 633 signal input board, 634 signal board, head, head signal input board, head screw 07, head screw 08, and LCD display panel.

[0046] The system implements its functions based on mobile or PC terminals. Users transmit commands to the central control unit through text retrieval or voice input of fault information on mobile or PC terminals. The central control unit receives the commands and responds accordingly, controlling the disassembly and assembly process of the corresponding modules or accessories and displaying them in the form of VR.

[0047] For example, the system transmits commands to the central control unit by inputting the name of a module or accessory to query the corresponding disassembly or assembly process and the corresponding common fault points, which is simple and quick.

[0048] In addition, each common failure point has the location and disassembly of the corresponding module or accessory.

[0049] For example, the system may also transmit commands to the central control unit by reversely querying the disassembly and assembly process of the corresponding module or accessory through common faults, which is also simple and fast.

[0050] Furthermore, the system also transmits commands by querying the accessories to obtain the standard number and product number associated with the accessories, so as to quickly find the corresponding accessories that can be used for replacement.

[0051] In addition, in the virtual scene, there are also quick operation functions, such as the option to restore, disassemble, restore, initialize, make transparent, highlight, etc. all modules or accessories.

[0052] For example, VR training scenes also include transparent operations, which are to display the modules and accessories that need to be understood in high brightness, while transparently displaying and processing other parts that are not related to the modules and accessories. VR training scenes can also rotate and display the surfaces and structures of each module or accessory 360 degrees without blind spots through operating instructions. Deliberately saving the manpower and time costs of visiting the site, disassembling the machine, and replacing accessories.

[0053] In general, using text or voice input and quick operations to transmit commands can quickly determine the cause of the fault, eliminate the fault, facilitate maintenance and ordering of accessories, etc.

[0054] For training, it can be targeted at technicians of different levels, and can provide real-time technical and data references. It can effectively solve the difficulties faced by various maintenance personnel who do not understand the internal structure of the machine and have no idea where to start. It can quickly guide maintenance personnel on how to solve the faults, thereby quickly improving their technical level.

[0055] In the 3D online training system for the hemodialysis machine of the present invention, since it is equipped with a complete technical support system and maintenance database, the system is also equivalent to a spare parts query database and a maintenance dictionary, which can not only assist engineers and maintenance personnel on site to correctly troubleshoot and disassemble accessories, but also provide information such as the article number and serial number of the parts that need to be repaired or replaced.

[0056] The system of the present invention is used to conduct simulation assessment of actual maintenance level. By simulating VR simulation components, corresponding adjustments are made to the faults of the hemodialysis machine, so that the tester can solve the possible faults of the hemodialysis machine during operation through virtual operation, and the simulation assessment is carried out to improve the actual operation ability of the college.

[0057] The present invention realizes a 3D online training system for hemodialysis machines based on VR technology, which truly reproduces the process of disassembly and restoration of the equipment, realizes online teaching and training of the hemodialysis machines, and completes the training without on-site teaching, thereby reducing the consumption of manpower and time costs caused by personnel turnover. It has a wide audience range and is suitable for on-site maintenance personnel and / or trainees with varying levels of skills. The entire system brings the advantages of significantly reducing maintenance costs, improving maintenance efficiency and increasing training effects.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
