Description

The technical field to which the utility model belongs.

The utility model relates to the field of teaching aids, namely, simulators for practicing first aid skills, including a mannequin torso with a head inside which sensors are placed that respond to resuscitation measures connected to an information processing unit and can be used to study cardiac pulmonary resuscitation. In this work, the terms are used:

Resuscitation measures - the actions of a medical worker in case of clinical death, aimed at maintaining the functions of blood circulation and respiration and revitalizing the body. In this context, we mean the training of such actions by the user of the simulator. An example would be massage, pressure on certain areas, changing the position of some parts of the simulator in relation to others.

Sensors that respond to resuscitation measures - sensors that convert the user's movements into electrical signals, mainly tensometric, optical and magnetic, see, for example:

The level of technology.

With the advent and development of computer technology, the devices used in education, in particular teaching devices, began to develop. They began to be connected to computers, and using computers to control the functions of learning devices. So known from the prior art is a simulator for practicing first aid skills, including a mannequin torso with a head inside which are sensors that respond to resuscitation measures connected to an information processing unit, see patent for utility model of the Russian Federation No. 138357, published on 03/10/2014. This simulator for practicing first aid skills is the closest in technical essence and the achieved technical result and is selected for the prototype of the proposed utility model.

The disadvantage of this prototype is the inability to visualize the internal organs of a person involved in the resuscitation process and the dynamics of internal processes necessary to study the technique of cardiopulmonary resuscitation. This does not allow visual feedback between the actions of the user and the state of the victim’s body, simulated by the simulator. That is, the trainee (the user of the simulator), exerting an impact on the simulator, does not see what happens to the internal organs of a person.

Disclosure of a utility model.

This useful model mainly aims to offer a simulator for practicing first aid skills, including a mannequin torso with a head inside which sensors are placed that respond to resuscitation measures connected to an information processing unit, which allows at least to smooth out the above-mentioned disadvantages, namely, to provide the ability to visualize the internal organs of a person involved in the resuscitation process and the dynamics of internal processes necessary to study those nicknames of cardiopulmonary resuscitation, which is a technical task.

To achieve this goal, the information processing unit is configured to generate and transmit a signal to an external rack with a projector for imaging on a mannequin, while the surface of the mannequin is a projection surface configured to display signals from the projector corresponding to the internal human organ involved in the resuscitation process measures and dynamics of internal processes necessary for the study of cardiopulmonary resuscitation techniques.

Thanks to these advantageous characteristics, it is possible to display visual information about what happens inside the victim’s body during certain actions of the simulator user, which allows the user to distinguish correctly performed actions from incorrect ones and, thus, significantly increase the effectiveness of training on the simulator.

There is a variant of the utility model in which the information processing unit is configured to receive a control signal from a wireless touch remote control. Thanks to this advantageous feature, it becomes possible to increase the usability of the simulator.

The set of essential features of the proposed utility model is unknown from the prior art for devices of a similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model is met.

A brief description of the drawings.

Other distinguishing features and advantages of this utility model clearly follow from the description below for illustration and not being restrictive, with reference to the accompanying drawings, in which:

- figure 1 depicts a General view of the simulator for practicing first aid skills, according to the utility model,

- figure 2 depicts a functional diagram of a simulator for practicing first aid skills, according to a utility model,

- figure 3 schematically depicts the steps of using a simulator to practice first aid skills, according to a utility model.

According to figures 1 and 2, the simulator for practicing first aid skills includes a mannequin torso 1 with a head inside which sensors 2 are placed, which respond to resuscitation measures connected to the information processing unit 3. The simulator is connected to an external rack 4 with a projector 5 (which are not objects of the utility model) for image formation by transmitting a signal from the information processing unit 3. The surface 6 of the mannequin 1 is a projection surface, configured to display from the projector 5 the internal organs of a person involved in the resuscitation process and the dynamics of internal processes necessary to study the technique of cardiopulmonary resuscitation.

The simulator can additionally be used together with an external wireless touch remote control 7 remote control.

The projector 5 may have a different device. Here is a description of some options for its execution.

1. CRT tube.

In such a projector, there are three cathode ray tubes. Each of them is responsible for its color - red, blue or green, from which the image is formed. The desired color is formed by the color filter behind the tube. The choice of colors is based on the fact that it is from these three primary colors that all the other colors of the spectrum can be formed, and in the RGB color system (Red Green Blue), a great many devices that form the video signal work.

2. Laser projector.

The image is formed due to the radiation of three (sometimes more) lasers. The laser array forms three beams of the same colors, which are then mixed. The image is created by the focus and scan system, which contains a special system of mirrors. Image formation by such a projector is similar to a picture on a CRT screen of a TV - the laser beam “circles” the projection screen from top to bottom up to 50 times per second, and the human eye perceives the resulting picture as a whole.

3. Projector based on LCD matrix.

The basis of the technology is the use of an LCD matrix "in the light". The lamp light, passing through the LCD matrix as through a filmstrip or film, and then through the lens, passes through many layers of the matrix and color filter.

4. 3LCD projector

Three LCD matrices allow you to create an image of much better quality than using a single matrix, by dividing the light flux and passing it through only one LCD panel, and not through three color filters in series. This guarantees greater brightness and additional picture quality, especially in terms of clarity. The system of dichroic mirrors divides the light into three color components, each passing through its own LCD matrix, and then the prism collects all three images into one picture.

5. DLP micromirror technology

The light of a powerful lamp is reflected from a special chip (Digital Mirror Device) containing thousands of micromirrors, each of which is responsible for its own image pixel. The matrix with mirrors is very tiny, usually about one inch. Each of millions of micromirrors is individually controlled, and as a result, a very clear and clear picture is created, devoid of flicker and artifacts inherent in liquid crystals.

6. D-ILA Projector (LCOS)

The image in this technology is formed by liquid crystals, however, it does not work in the light, as usual LCD matrices, but in reflection, and sometimes, to simplify the understanding of its essence, the technology is called “reflective liquid crystal panels”. The main difference from the usual LCD matrix is that the entire electronic "filling" is located behind a layer of liquid crystals under the reflecting electrodes, and not between the cells. This provides the best fill factor - the image is formed on a larger area of the matrix, and the minimum area remains unused. The luminous flux is formed by a weak light source, and then amplified by a special lamp, which is why the name of the technology occurs.

The external stand can be made as a floor design, which allows the projector to be fixedly fixed, as well as to adjust its orientation in space, for which the external stand can have adjustable consoles with adjusting bolts.

The simulator can be controlled to train first-aid skills remotely using a wireless touch remote control, which can be, for example, a tablet computer, mobile phone or a separate device.

In order to maximize the approximation of students to real situations that arise when interacting with a simulator simulating a victim, sound can be played.

All connections between the information processing unit and the projector can be made both in the form of a wired connection, when information is transmitted in the form of electric pulses traveling through wires, and in the form of any wireless connection, which includes various topologies, configurations, and layouts of the components of the interconnection made with the ability to interconnect corporate, global and local area networks, and includes, without limitation, traditional wireless, satellite, optical Equivalent and equivalent network technologies. In figure 2, the connection is conventionally shown by wire through an electric wire 8.

Sensors 2 can be strain gauge, capacitive or other, which allow you to convert clicks with your fingers or changes in the position of the parts of the simulator into electrical signals.

The arrow and the letter g in figures 1 and 2 are conventionally indicated the direction of gravity.

Additionally, the mannequin can be equipped with limbs.

Implementation of a utility model.

A simulator for practicing first aid skills works as follows. We give the most comprehensive example of the implementation of the utility model, bearing in mind that this example does not limit the use of the utility model.

According to figure 3:

Stage A1. The torso of a mannequin with a head, designated as 1, is placed on a flat surface, for example, on a table.

Stage A2. Install the projector 5 on the stand 4 and direct it so that the image from it is shown exactly on the projection surface 6 of the mannequin 1. To do this, adjust the height of the projector and its tilt angles using, for example, the adjusting bolts included in the drains 4. On figures not shown.

Stage A3. The projector 5 is connected to the information processing unit 3.

Stage A4. Connect the wireless touch remote control 7 to the information processing unit 3.

Stage A5. Manual resuscitation is carried out by the user of the simulator, while the sensors 2 respond to the significant actions of the specified user.

Stage A6. Depending on these signals, the information processing unit 3 generates control signals to the projector 5, which transmits the corresponding video information to the projection surface 6 of the mannequin 1.

The sequence of steps is exemplary and allows you to rearrange, decrease, add or perform some operations at the same time.

Industrial applicability.

The proposed simulator for practicing first aid skills can be carried out by a specialist in practice and, when implemented, ensures the implementation of the declared purpose, which allows us to conclude that the criterion is “industrial applicability” for the utility model.

In accordance with the proposed utility model, a prototype simulator was made for practicing first aid skills.

Tests of the prototype system showed that it provides the ability to:

- demonstrations of the state of clinical death with light-dynamic indication of ongoing activities, with the following modes:

- Training and demonstration mode;

- Resuscitation mode by one rescuer;

- Resuscitation mode by two rescuers;

- Resuscitation regimen recommended by the European Resuscitation Council (ERC).

- Demonstration of the state of clinical death with disabled light-dynamic indication of ongoing activities for exams and competitions. With proper cardiopulmonary resuscitation, the dummy has narrowed pupils, a pulse appears on the carotid artery, and spontaneous breathing appears.

Additionally, a mode for controlling the operation of the complex using a wireless touch remote control is implemented.

Thus, in this utility model, the task is achieved - providing the ability to visualize the internal organs of a person involved in the process of resuscitation and the dynamics of internal processes necessary to study the technique of cardiopulmonary resuscitation.
