Description

The utility model relates to devices, systems and medical products used to monitor the condition of a parachutist-rescuer during the course of his activities in the interests of solving applied problems of the physiology of work activities.

The closest analogue known from the state of the art is a device for diagnosing the functional state of a human operator (patent for utility model RU 223094), which consists of a housing made in the form of a rectangular parallelepiped with rounded corners, inside which a microcomputer, a storage device with non-volatile memory, a battery and a wireless interface unit are fixed; a USB connector, a connector for connecting a pulse rate sensor, a connector for connecting a respiration rate sensor, a connector for connecting a body temperature sensor, a connector for connecting a human skin humidity sensor, a connector for connecting a pulse oximetry sensor and a connector providing interfacing with the automatic control system of the ergatic system and with a parametric recorder of information on its functioning are mounted in one of the outer side edges of the housing flush with its surface; a digital display, a speaker and a three-mode light indicator are mounted in the outer side edge of the housing adjacent to it; a storage device with non-volatile memory, a wireless interface unit, a USB connector, a connector for connecting a pulse rate sensor, a connector for connecting a respiration rate sensor, a connector for connecting a body temperature sensor, a connector for connecting a human skin moisture sensor, a connector for connecting a pulse oximetry sensor, a connector that provides interfacing with the automatic control system of the ergatic system and with a parametric recorder of information about its operation, a digital display and a three-mode light indicator are connected by wires to a microcomputer; an information receiving unit, a USB connector, a connector for connecting a pulse rate sensor, a connector for connecting a respiration rate sensor, a connector for connecting a body temperature sensor, a connector for connecting a human skin moisture sensor, a connector for connecting a pulse oximetry sensor, a digital display, a speaker, a three-mode light indicator and a microcomputer are connected by wires to a battery; the outer side edge of the housing opposite the edge with the digital display is made of a material with magnetic properties and is equipped with a mount built flush with the surface of the edge; wherein the housing is made in a dust- and moisture-proof, shock-proof, fire- and explosion-proof design; a video camera, an air temperature sensor, an air humidity sensor, and a serviceability indicator, connected to a microcomputer, and a solar battery connected to a battery are built into the upper edge of the housing flush with its outer surface; and the microcomputer is designed with the following capabilities: issuing information to the automatic control system of the ergatic system to the parametric recorder of information about its operation, adaptive control of the polling frequency of the connected sensors, processing the image of the face of the human operator obtained from the video camera, which makes it possible to obtain quantitative characteristics of emotions, and calculating an assessment of the functional state of the human operator of the ergatic system based on the values of air temperature, air humidity, pulse rate, respiratory rate, body temperature, skin humidity, the results of processing the image of the operator's face obtained from the video camera, and the oxygen saturation of hemoglobin in arterial blood obtained from the output of the pulse oximetric sensor, with all components in the device housing being connected according to the "active star" topology using a cable, the center of which is the microcomputer located in the housing.

The disadvantage of this technical solution is as follows. At the workplaces of parachutists-rescuers located on board aircraft (planes, helicopters) during work in flight (monitoring the territory of fires, floods, earthquakes and other emergency situations), a low (-40°) ambient temperature is recorded. These conditions in terms of the temperature factor do not correspond to the permissible (defined in the technical documentation and instructions) conditions for the possible operation of the components of the declared device, which causes failures and malfunctions in the device. Failures and malfunctions in the device are also caused by low barometric pressure (the barometric pressure in unpressurized cabins/cabins of aircraft is below the minimum permissible barometric pressure (specified in the technical documentation and instructions for the components of the device).

Using a cable, the components in the device body are connected according to the “active star” topology, the center of which is a microcomputer located in the body.

Before using the claimed device:

it is secured to the parachutist-rescuer's equipment or gear using a mount and/or a magnetic side edge of the housing so that the display and three-mode indicator are visible to the parachutist-rescuer - the user of the device;

sensors of state indicators necessary for calculating the integral indicator of the functional state (sensors of pulse rate, respiratory rate, body temperature, oxygen saturation of arterial hemoglobin and skin moisture) are built into the equipment of the parachutist-rescuer - the user of the device, connecting them to the device body through specially available connectors (the discreteness of information transmission in the process of professional activity is determined by a microcomputer located in the body).

Microcomputer located in the case:

using pre-set algorithms (formulas), it calculates an assessment of the functional state of the parachutist-rescuer based on the values of air temperature, air humidity, pulse rate, respiratory rate, body temperature, skin humidity of the human operator, oxygen saturation of arterial hemoglobin and the results of processing the image of the parachutist-rescuer's face obtained from a video camera;

generates a signal that determines the glow mode of the three-mode light indicator, records information in a storage device with non-volatile memory;

generates speech information that is presented to the parachutist-rescuer through a speaker.

The health indicator, connected to the microcomputer, shows the good (green glow) and bad (red glow) state of the device.

A solar panel connected to the battery provides its recharging. Recharging of the battery and, if necessary, connected sensors can also be done through the existing connectors.

The information on the display and the current indicator light are updated by command from the microcomputer located in the housing.

Using the claimed device, the parachutist-rescuer is provided with information about the current functional state.

The professional activity of a parachutist-rescuer is associated with jumping from heights of up to 10 thousand meters - these conditions are characterized by low atmospheric pressure and low air temperature, which negatively affect the operation of sensitive elements of sensors and microelectronic components. Therefore, to ensure correct diagnostics of the intensity of the work process of a parachutist-rescuer, it is necessary to ensure that the sensors and microelectronic components included in the device are in conditions corresponding to the range of their application specified in the passport data. Therefore:

the device body the body is made in a sealed design, it has a built-in air pressure control unit (connected by wires to a microcomputer and battery), which ensures that the air pressure inside the body is maintained in the range corresponding to the requirements of the regulatory and technical documentation of sensors and microelectronic components;

the walls of the housing are made hollow, the cavities are filled with heat-insulating material - taking into account that the execution of a parachute jump (taking into account the rise of the parachutist-rescuer to the required height and to the required point of the jump) takes about several hours, the heat-insulating material ensures that the temperature inside the housing of the device is maintained in accordance with the requirements of the regulatory and technical documentation of sensors and microelectronic components.

Thus, the goal of applying the claimed technical solution has been achieved.

The described elements of the claimed device are functionally interconnected, and the totality of its essential features is unknown from the state of the art - that is, the claimed device represents a new technical solution with industrial applicability.
