[0028] DETAILED DESCRIPTION OF THE INVENTION

[0029] In the following detailed description of the embodiment of the invention, numerous implementation details are set forth in order to provide a clear understanding of the present invention. However, it will be apparent to one skilled in the art how the present invention may be used with or without these implementation details. In other instances, well-known methods, procedures, and components have not been described in detail in order not to unnecessarily obscure the features of the present invention.

[0030] In addition, it will be clear from the above description that the invention is not limited to the embodiment shown. Numerous possible modifications, changes, variations and substitutions, preserving the essence and form of the present invention, will be obvious to those skilled in the art.

[0031] Terms and definitions.

[0032] Virtual reality is a world created by technical means, transmitted to the user through his senses: sight, hearing, touch, etc. Virtual reality simulates both impact and reactions to impact.

[0033] A controller is a control device in electronics and computing.

[0034] Nursing is a part of the health care system that includes activities to improve public health, prevent diseases, provide psychosocial assistance and care to people with physical and mental illnesses, as well as disabled people of all groups.

[0035] Simulation is the imitation of a physical process using an artificial (e.g. mechanical or computer) system.

[0036] Tracking is the process of determining the location of moving objects over time using a camera.

[0037] A paramedic is a specialist with secondary specialized medical education who has the right to conduct diagnostics and establish a diagnosis, conduct independent treatment or refer a patient to a specialist doctor.

[0038] Computer technologies are actively used in the educational process almost all over the world. The creation of educational computer simulators is one of the key areas in the computerization of education. Full immersion in virtual reality and interaction with its objects is achieved only with the use of special devices. Such devices that provide full immersion in virtual reality and simulate the user's interaction with it using the senses are called virtual reality (VR) systems. An important factor in increasing the level of immersion in the virtual environment is the ability of the user to interact with elements of the environment and characters in virtual reality.

[0039] The use of simulation techniques is driven by the need to ensure patient safety, provide planned practice, and provide sufficient repetitions to develop practical skills.

[0040] Demonstration of symptoms and the opportunity to practice practical examination skills on real patients is difficult, since it is impossible to plan the presence of patients with all the symptoms required for mastering during the clinical rotation of students. Moreover, most patients refuse to interact with students, as they experience discomfort and pain during examination by students. In patients with acute pathology, in addition to pain, repeated examinations by students can lead to complications, as well as a delay in providing the necessary emergency care. At the same time, multiple repetitions and the opportunity to observe symptoms in different patients are required to acquire stable skills.

[0041] Thus, the acquisition of skills for examination and recognition of pathologies is significantly complicated, which subsequently leads to incorrect interpretation of information obtained during examination of patients.

[0042] Thanks to the proposed technical solution, the learning user sees the environment, interactive objects, an animated interactive patient and can practically safely interact with them. This approach increases the depth of immersion, expands the possibilities of interaction, and also allows for the implementation of automated complex objective assessment systems for user actions.

[0043] This technical solution is designed for safe, practical training and assessment of skills of mid-level medical personnel, without risk to patients and trainees, in a realistic simulation environment, with a comprehensive automated assessment system based on the principles of national guidelines.

[0044] More precisely, the solution is designed for safe and practical training of nurses and paramedics. The solution allows them to learn basic patient care skills, clinical thinking, communication skills and action algorithms in various simulated clinical cases, abnormal and emergency situations with a wide range of virtual patients.

[0045] Fig. 1 illustrates an example of a dynamic virtual environment (location "Emergency Department"). This virtual location is used to practice the skills of a nurse in the event of an emergency and can be displayed to the training user. In a particular version, the solution allows the user to visually assess the general condition of the virtual patient, skin (color, moisture or dryness, presence of rash); monitor the main parameters of the cardiovascular and respiratory systems; and establish verbal contact with the patient.

[0046] To implement this technical solution, seven different virtual models of patients were developed. For each patient, a character skeleton was developed for further animation of actions and work with interactive objects (Fig. 2). All models have the ability to work with Lip sync technology (synchronization of the character's lip movement with sound) for realistic training and practice of communication skills with the patient, clinical thinking, actions in emergency situations, etc.

[0047] Depending on the clinical case, additional pathologies and external manifestations (cyanosis, sweat, redness, etc.) are developed for the patient. Patient models are developed taking into account the possibility of realistic demonstration and practice of the correct sequence of actions for performing manipulations, compliance with sanitary and epidemiological rules and safety rules.

[0048] To implement this technical task, the following virtual patient models were developed:

[0049] 1. A middle-aged man with obesity (Fig. 4);

[0050] 2. Young man (Fig. 5);

[0051] 3. Middle-aged man (Fig. 6);

[0052] 4. Middle-aged woman (Fig. 7);

[0053] 5. An elderly man;

[0054] 6. Child;

[0055] 7. Young girl.

[0056] Virtual tools have been developed for locations and patients in accordance with clinical cases (scenarios). For the initial level of training, it is possible to train basic skills such as performing injections, taking an ECG, correctly applying and connecting various sensors to the patient, installing catheters, caring for a postoperative wound, and many others.

[0057] Virtual instruments are adapted to each existing patient model and have logic with rules for their use and application to the patient.

[0058] To implement this technical solution, the following virtual instruments have been developed:

[0059] 1. Infusomat

[0060] 2. Oxygen humidifier

[0061] 3. Defibrillator

[0062] 4. Nasal cannula

[0063] 5. Peripheral venous catheter.

[0064] 6. Full face oxygen mask.

[0065] 7. ECG electrodes.

[0066] 8. Flashlight to check pupil reaction to light.

[0067] 9. Urinary catheter.

[0068] 10. Pulse oximeter connected to a bedside monitor.

[0069] 11. Central venous catheter

[0070] Infusomat is a device designed for long-term, dosed, controlled administration of solutions, highly active drugs, and nutrients to a patient. The mechanics of choosing a drug, its dose, and the rate of administration were implemented for it.

[0071] The defibrillator has a mechanism for operating the device and applying it to the patient (Fig. 8).

[0072] All tools are necessary for the implementation of the mechanics embedded in the scenarios. Each virtual tool is linked to the simulator's evaluation system for further verification of its correct use depending on the scenario.

[0073] A nasal cannula is a virtual device used instead of an oxygen mask for patients. It consists of plastic tubes that are inserted 1-2 cm into each nostril of the patient and through which oxygen enters the nasal cavity. At the other end, the tubes are connected and connected to an oxygen system, which can be a portable oxygen cylinder or a central oxygen distribution system. The nasal cannula has a mechanics for connecting to the patient.

[0074] Central venous catheter - in medicine for catheterization of central veins (internal jugular vein, subclavian vein, femoral vein). The central venous catheter is used for faster administration of infusion solutions and drugs, parenteral nutrition, blood sampling, etc. compared to a needle.

[0075] All instruments that contain flexible tubes are animated under the idle animation of the virtual patient.

[0076] Fig. 9 illustrates virtual instruments laid out on a medical table, where 4 is a nasal cannula, 5 is a peripheral venous catheter, 6 is a full-face oxygen mask, 7 is ECG electrodes, 8 is a flashlight for checking pupillary response to light, 9 is a urinary catheter, 10 is a pulse oximeter connected to a bedside monitor, 11 is a central venous catheter.

[0077] To implement this technical solution, scenarios were developed in the following categories:

[0078] 1. Patient care;

[0079] 2. Diagnostic procedures;

[0080] 3. Treatment measures;

[0081] 4. Providing emergency care;

[0082] 5. Preventive measures;

To implement scenarios and simulate real user-patient interaction, manipulation mechanics required in the scenarios of this technical solution were developed. A list of some mechanics is given in Table 1.

[0183] Table 1 - Developed mechanics and their description.

[0184]

[0185]

[0186] The implementation of the above and similar mechanics and interactions with patients and instruments is possible, for example, using the Oculus Quest 2 device controllers. In each scenario, the mechanics are implemented with the achievement of maximum compliance with real human movements when performing such manipulations in reality. User manipulations and interactions, meaning the capture of objects or other control, different from the usual in reality, are replaced by pressing buttons on the input device of the Oculus Quest 2 controller. The implementation of the solution as a whole is possible using autonomous VR systems (OS: Android, CPU: Qualcomm Snapdragon XR2, RAM: from 6 GB, ROM: 64 GB).

[0187] The mechanics for evaluating user actions are designed taking into account the key stages of the scenario and the expected actions at each stage.

[0188] The key stages that can be identified in each scenario are:

[0189] • Dialogue with the patient.

[0190] • Carrying out manipulations with the patient.

[0191] • Reaction to the patient's responses and condition.

[0192] • Prescribing correct / incorrect (unnecessary) drugs / treatments / tests.

[0193] The evaluation criteria also include taking into account the speed of the actions performed, their correctness and the ranges of parameters that cannot be exceeded during the work in the simulator in each case. After completing the scenario or stage, the user is provided with feedback on its results.

[0194] The basic diagram of the algorithm of the user action evaluation system is shown in Figure 10.

[0195] In this case, the evaluation criteria and user actions tracked for scenarios may be different. The blocks “Comparison with expected actions” and “Record errors and deviations” have different appearances, depending on the scenario and set of initial parameters. As a result, the evaluation scenario and the set of indicators and expected user actions affecting the result for cases may be unique. Logical schemes were developed for the system of evaluation of various diseases, for example, angina, hypoglycemia, etc. An example of a logical scheme is shown in Figure 11.

[0196] As a result of each executed scenario, the user receives:

[0197] • An assessment: This could be a percentage, points, or other metric that reflects his or her performance. • Detailed feedback: A list of actions performed correctly, errors made.

[0198] • Statistics: Time, date of execution and other quantitative metrics. An example of the implementation of this technical solution.

[0199] An animated interactive patient (e.g., see Fig. 6) and a dynamic virtual environment are transmitted to the learning user in real time on a display device (e.g., virtual reality glasses). The animated interactive patient is located in a dynamic virtual environment (e.g., see Fig. 1) and is generated by a computing system (e.g., a virtual reality system) using a virtual model of the patient, which is implemented on the basis of a library of nursing scenarios.

[0200] The learning user, during the practical training of professional medical skills (e.g., see Fig. 8), interacts with an animated interactive patient (practically performs manipulations with the patient, based on the mechanics and scenarios described earlier), as well as with a dynamic virtual environment and virtual instruments. The main variations of user interactions can be considered: a user dialogue with a virtual patient; performing manipulations with a virtual patient; the user's reaction to the answers and condition of the virtual patient; the user's prescription of correct / incorrect (unnecessary) drugs / treatment / examinations.

[0201] The interaction of the learner with the animated interactive patient is possible by means of at least one input device (e.g. by means of sensors with optical finger tracking or other input devices). All user interactions with the animated interactive patient are sent from the input device to the computing system, where all actions / inactions of the learner user are analyzed (the scenario is compared with the user's actions). In response to all actions / inactions of the learner user, the computing system generates and reproduces on the display device an audio and video stream in the form of motor, speech and facial reactions of the animated interactive patient (with the ability to visualize pathological changes in its condition in accordance with the scenario).

[0202] Additionally, all manipulations of the learning user with the animated interactive patient, within the session and scenario, are recorded and written to the local database. Based on the recorded and saved data, at the end of the training session and / or scenario development, the computing system evaluates the correctness of the actions performed by the learning user. This stage is carried out by comparing the saved actions and manipulations of the user with the corresponding, pre-set, correct actions and manipulations embedded in the scenario library.

[0203] The present application materials present a preferred disclosure of the implementation of the claimed technical solution, which should not be used as limiting other, particular embodiments of its implementation that do not go beyond the scope of the requested scope of legal protection and are obvious to specialists in the relevant field of technology.
