Description

Device for screening dynamic monitoring of health status and Integrated peripheral pulse sensor unit

The utility model relates to medical equipment and can be used both for conducting screening examinations of the contingent of working people in a production environment, and for self-monitoring the health status of users of personal computers in home or industrial settings.

The current level of medical technology allows both the registration of heart rhythm and the analysis of its various indicators to assess the state of the cardiovascular system. Based on this, it is possible, in turn, to determine indicators of a person’s health and physical condition.

Various devices are known that contain bioinformation removal sensors, both stationary and portable, as well as processing units for this bioinformation and its analysis, the operation of which is based on a comparison of recorded bioinformation indicators (initial and

after a test exposure) with regulatory data for the subsequent formation of a medical opinion.

A device is known (see the description of US patent No. 4022192 class A61, 5/04, 05/10/07,), providing the determination of the integral parameters of the cardiovascular system through a certain number of cardio intervals. The device comprises a pulse sensor unit, a pulse unit, a control unit, a digital information output unit, and a cardiovascular system parameter determination unit. However, this device does not allow to determine the variance (standard deviation) of the R-R intervals, which is one of the determining parameters in the assessment of generalized indicators of the state of the cardiovascular system.

In the known device for determining assessments of particular indicators of health status (Cardiovascular Autonomic Funcnion Test Sestem MEDIKRO CAFTS, Medicro OY, Kuopio, Finland) based on the assessment of cardiovascular autonomic regulation according to the data on the dynamic response of the heart rhythm, R-R intervals are selected during ECG recording. The survey results are presented on the information output unit in the form of textual (list of symptoms and syndromes), digital and graphic materials, the subsequent analysis of which allows the specialist physician to formulate a Conclusion with relevant recommendations. The need to use sophisticated ECG equipment to isolate R-R intervals makes the device cumbersome and expensive.

A device for active diagnostics is known (see patent application of Russia N 97115576 of September 24, 1997, for which a positive solution was obtained), which provides the determination of R-R intervals from a pulse wave recorded using a peripheral pulse photoelectric sensor.

The device is made in the form of complex blocks enclosed in separate cases, interconnected by a connector block. One of them is made in the form of a complex block of a peripheral heart rate sensor, the other - in the form of a complex software and hardware block

containing a high-pass bandpass filter, a real-time RR interval determination unit, a normative data and anthropometric patient data memory unit, a unit for determining private and generalized diagnostic indicators, a combined bioinformation memory unit, an individual recommendations generation unit, a visual information output unit, a display, a printer and control panel for entering anthropometric patient data and control commands.

The device also contains a number of other blocks, the combination of which ensures not only the efficiency of the survey, achieving compactness and ergonomics of execution, but also the automation of the formation of a classification conclusion based on the results of the survey.At the same time, the role of the operator in conducting the survey is reduced mainly to preparing the device for operation.

The objective of this technical solution is to create a device that extends the functionality and provides (without the involvement of medical personnel) the dynamic self-monitoring of the state of health directly in the process of performing basic work at work or at home, as well as ensuring the operational implementation of pre-shift monitoring of the health status of workers in those specialties, whose work is associated with responsibility for the lives of others, such as nuclear power plant operators, eticheskih settings, drivers, pilots, etc.

The problem is solved in that the known device according to the application N 97115576, taken as a prototype, is additionally equipped with blocks:

preliminary accumulation of rows of R-R intervals and their sorting,

the formation of individual classification boundaries of indicators,

formation of a communicative function and its analysis,

generating a signal to turn off the main device.

In this case, the block of preliminary accumulation of rows should be made in the form of subunits of accumulation: current rows of R-R intervals, incomplete rows of R-R intervals, composite rows of R-R intervals and

full rows of R-R intervals so that the accumulation sub-block of incomplete rows is associated with the sub-block of accumulation of composite rows through the block combining incomplete rows of R-R intervals.

In addition, the normative data memory block should be equipped with a memory block of classification boundaries of normative indicators, and the classification analysis block should be made in the form of sub-blocks for analysis of indicators and classification boundaries analysis, while the latter should be provided with input from the memory block of classification boundaries of normative indicators and from the unit for determining private and generalized diagnostic indicators through the unit for the formation of classification boundaries of normative indicators, and the unit for the formation of the communicative function its analysis unit placed between the analysis and classification block forming individualized advice and link operation mode control unit through the signal conditioning unit to turn off.

In the proposed device, the block diagram of the Complex block of the peripheral pulse sensor is made similar to the block diagram of the prototype, i.e. with the ability to perform pulse wave removal operations, converting the signal into a digital code and transmitting it to the Integrated software and hardware unit.

The surface of the housing of the sensor unit is made with the possibility of contact of its working section (zone of the lens of the optocoupler) with the section of the pulsating tissue of the body surface (finger, neck, earlobe, etc.).

The implementation of the block diagram of the Integrated software and hardware block can be performed on the element base of computer technology, including those used in personal computers.

In this application, as an independent technical solution, the design of a finger peripheral pulse sensor is considered, which can be used both in the inventive device and in similar other devices for recording and processing pulse wave parameters, for example, in a lie detector.

As an independent technical solution, the Integrated peripheral heart rate sensor unit can be used as a tool that allows self-monitoring of the health of users of personal computers.

A device for input into a computer is known (see WO 9601585 A1, A61B5 / 00), made in the form of a computer mouse, on the surface of which there are means for measuring one or more physiological or biological parameters, for example, heart rate, body temperature and skin electrical conductivity. The information obtained in accordance with known methods is used to assess the degree of arousal (stress). The results are displayed on the computer display. This device can be used to assess the degree of stress stress of a PC or patient, as well as to monitor the process of stress relaxation.

Analysis of the constructive solution of the mentioned invention for the implementation of the task showed that it is impossible to use this design in the device proposed by the authors as a finger sensor. This is due to the fact that the known solution does not provide the pulse wave survey necessary to obtain the variational series of R-R intervals, which are the main input information for the screening control of the dynamics of the state of health for the Complex hardware-software unit.

In addition, the design of a computer mouse known from the patent is practically deprived of the ability to carry out its direct function, since it is overloaded with means for measuring physiological parameters.

In the known diagnostic device according to the patent application of Russia N 97115576, the Integrated peripheral pulse sensor unit contains an optocoupler unit with a matching cascade integrated in the housing, connected to the galvanic isolation unit through a series-connected low-pass filter, a parallel code to serial converter, an analog-to-digital converter block (ADC), a complete code transmitter unit, as well as a clock and

a frequency divider, while the clock generator has one connection with the parallel code to serial converter unit through the frequency divider and a second connection with it through the analog-to-digital converter unit, and the housing has holes for accommodating the lenses of the infrared emitter and the optocoupler photodetector on the area of its upper surface. At the same time, the block diagram for constructing the sensor is implemented on two boards, one of which has an infrared emitter and a photodetector, and the second contains all the other blocks of the circuit that implement the conversion of the analog signal into a numerical form and prepare it for subsequent transmission.

The housing of the sensor unit is equipped with a clamping device for fixing the finger.

The sensor unit is informationally connected to the Integrated software and hardware unit through a connector block.

The peripheral pulse sensor unit considered above provides a high-quality pulse wave and can be used as a prototype of the proposed technical solution in terms of taking a pulse wave, converting an analog signal to a number and preparing it for transmission to the Integrated software and hardware unit. However, the objective of this technical solution is to expand its functionality, namely: providing high-quality pulse wave capture and transmitting it in digital form to a further processing device at the same time as carrying out the main professional work, for example, of a PC user.

The task can be solved if, in the sensor case, an electromechanical unit of a traditional device for entering coordinates and commands (a computer mouse) is additionally placed, with the ability to connect to a PC, and the board that implements the function of converting an analog signal to a number and preparing it for transmission can be removed from housing the sensor unit and place in the connector plug housing. In addition, the clip for fixing the finger should be made removable.

This allows us to consider the proposed technical solution as a solution that provides the creation of essentially two functional devices. In accordance with this, there are three possible options for the operation of the Complex unit of the peripheral pulse sensor:

conducting dynamic screening of the health status (in the background) while the user (operator) is performing his main professional work (first mode of removal),

conducting dynamic dynamic health screening (continuous examination mode) without the operator performing his main professional work (second pickup mode),

the operator conducting his main professional work without carrying out dynamic dynamic screening of the state of health (traditional operating mode).

in FIG. 3 shows a block diagram that implements the functions of converting an analog signal to a number and preparing it for transmission, located in the connector plug housing,

in FIG. 4 shows a structural diagram of the optocoupler of the sensor unit, in FIG. 5 shows a structural diagram of the housing of the sensor unit, side view.

A useful model of a dynamic dynamic monitoring screening device CONDITIONS of HEALTH contains the Integrated unit of the peripheral pulse sensor I and the associated Integrated software and hardware unit II.

The complex unit of the peripheral pulse sensor I is enclosed in an independent housing 1, on the surface of which holes 2 are made

and 3 for the exit of the optical lenses of the optocoupler, as well as an opening for the output of the connecting cables.

The integrated software and hardware unit II is enclosed in a housing 4 having a socket 5 for connecting a plug of a sensor block connector.

Inside Complex Block II, the following blocks are connected in series: a high-pass bandpass filter 6, real-time 7 rows of RR intervals, preliminary accumulation of RR intervals and their sorting 8, combined memory block of RR intervals 9, operating mode 10, memory private and generalized indicators 11, determination of diagnostic indicators 12, the formation of classification boundaries of indicators 13, classification analysis 14, the formation of the communicative function 15 and b approx forming individual recommendations 16 which via the control unit 10 associated with the visual information forming unit 17 having, in turn, outputs to the display 18 and printer 19.

Block 8 of preliminary accumulation of rows of R-R intervals and their sorting has subunits: accumulation of current rows of R-R intervals 8a, accumulation of incomplete rows of R-R intervals 8b, accumulation of composite rows of R-R intervals 8c and accumulation of complete rows of R-R intervals 8d. In this case, subblock 8b is connected to subblock 8c through block 20 combining incomplete rows of R-R intervals.

In addition, the device has a block 21 of normative data memory, consisting of a subunit 21 а - a memory of normative indicators and a subunit 21 in - memory of the classification boundaries of normative indicators.

Block 14 classification analysis also has two subblocks: subblock 14a - analysis of indicators and subblock 146 - analysis of classification boundaries. In this case, subunit 14a has inputs from block 12 and subunit 21a, and subunit 14c is from block 13 and subunit 21c.

Block 15 is additionally connected to the control unit 10 through the block 22 of the formation of the signal to turn off the device, the execution of which is carried out by the control unit for the execution of exchange operations. Is available

also a block 23 of the memory of personal characteristics associated with the block 11 of the memory through the block 10 of the control.

The following description of the operation of the utility model relates to a variant of the technical implementation of the proposed solution using the PC element base.

When you turn on the device for the first time, after installing the device, the PC user (operator) from the control panel 24 enters his standard personal information: last name, first name, year of birth (comprising the user code), height, weight, blood pressure, and also dichotomous (alternative) information character about playing sports.

These data go to the memory block 23 of the personal characteristics of the control and then to the memory block 11 of the private and generalized indicators. At subsequent starts, the user code is entered and only the information that has undergone a change, for example, blood pressure.

After that, he can start his main job, using a peripheral pulse sensor both to take a pulse wave and to perform standard actions typical of a coordinate manipulator of a computer mouse.

The signal captured by the optocoupler of a finger or other peripheral pulse sensor in digital form is fed through the socket of connector 5 to the filter 6.

At its core, the incoming signals are a temporal sequence of amplitudes (Aft)) of the pulse wave (points). In filter 6, at each current time tj (tj (10н-20) 1ДДСкр, where WKp «1 / 600c is the sampling period in time), the signal received in the time interval tj is numerically filtered. At the same time, a finite-length filter is used to ensure real-time operation. The choice of the time interval tflMCKp is due to the required accuracy in determining the signal amplitude A (tj). As a result of filtering, the time series does not contain those high-frequency

components, the presence of which could lead to the formation (in block 12) of an erroneous identification time stamp used in determining the value of the R-R interval. The filtered signal from the filter 6 is fed to the input of the block 7 determine the R-R intervals.

Then, in block 7, the signal is numerically differentiated (A (tj)) and, using mini-max algorithms, a maximum of the derivative A (t) is searched. The value of time t plays the role of the first identification time stamp in determining the value of R-R intervals. The second identification mark Г is set when a maximum of the derivative A (t) is found having a close amplitude value. The value of the time interval At t - t is used hereinafter as the value of the R-R interval. The current value of the number of the next R-R interval from block 7 is transmitted to the control unit 10, and the next value of the R-R interval itself is transmitted to block 8 of the preliminary accumulation of rows of R-R intervals and their sorting, i.e. in the subunit 8a accumulation of the current series of R-R intervals.

The number of R-R intervals continuously entering this block, i.e. the length (NRR) of the accumulated series of R-R intervals is determined by the nature of the timed mode of information retrieval — the duration of the finger’s contact with the peripheral pulse sensor. In the general case, as mentioned above, during the survey, two variants of the pulse wave pickup mode are possible: the background mode and the continuous examination mode.

Used here, the term operation of the device in the background is associated with an implementation option of the Integrated software and hardware block II using the PC element base. This means that the PC operating system performs some priority work, set by the user and displayed constantly on the display screen, and, at the same time, can perform a number of other tasks with a lower priority, including receiving and processing the signal from the peripheral heart rate sensor unit at what this work is either not displayed at all on the display screen or is displayed in a minimal amount.

The peculiarity of the background mode of removal is that the PC user, performing his main work, may not have the constant ability to monitor the duration of the contact of the finger with the peripheral heart rate sensor. The length of the recorded row may correspond to:

discrete reading of information when,

piecewise-continuous (in time) information retrieval when NRR NRR1 + NRR2 + ... + NRRj. + ... + NRRk, where 11 NRRj 100, and k is the number of continuous time-lapse intervals (1),

In the first case, when NRR 10, the received number of R-R intervals is not further processed and stored.

In the second case, despite the fact that each individually piecewise continuous row (11 NRR 100) is not representative enough (incomplete), their combination (combining according to certain rules) allows (with a certain error) to receive an assessment of diagnostic indicators. Therefore, these incomplete rows of R-R intervals are stored in a sub-block of accumulation of incomplete rows of R-R intervals 8b.

When the total length of these rows of NERR 140 is reached, they come from subblock 8b to block 20 combining incomplete rows of R-R intervals, where they are combined using certain algorithms (stitching). The method of conducting correct sewing without loss of diagnostically significant information and not leading to the appearance of artifacts is of independent interest and is considered by the authors as a subject of independent protection. The resulting time series comes from block 20 to block 8c of accumulation of composite rows of R-R intervals.

In the continuous examination mode conducted by the PC user for self-monitoring purposes, only the recommended testing examination is performed, while its main work is temporarily stopped or its execution is carried out in the background. The user uses a removable clip to fix his finger.

In this case, the length of the recorded row of R-R intervals (NRR) should be at least 100.

A series of R-R intervals (in the continuous examination mode), initially received in subunit 8a, then enters the subunit 8d of accumulation of complete rows of R-R intervals.

Further, depending on the current operating mode 1 or 2, a series of RR intervals Rm8d (mth in a row,, 2,3, ...) from a subunit 8d or Rn8c (pth in a row,, 2,3 ,. ..) from subunit 8c it enters the combined unit 9 of the memory of the rows of RR intervals, where separate accumulation of these rows occurs.

After that, through the control unit 10, the last of the accumulated series Rm8d (or Rn8c) is transmitted to the unit 12 for determining the current diagnostic indicators and then the private and generalized indicators of the health status of the PC user are determined, while the data on blood pressure coming from the private memory unit 11 are used and generalized indicators.

The set of private and generalized indicators obtained during previous work sessions, together with the current values of private and generalized indicators, are transferred to block 13 for the formation of individual classification boundaries of indicators, where they are corrected. Then, in block 14 of the classification analysis, which receives four data streams:

from block 12 - the current values of the diagnostic indicators,

from block 13 - the adjusted values of the individual classification boundaries,

from block 21 - age and gender values of normative indicators and

classification boundaries of normative indicators, a balanced assessment of individual boundaries and an assessment of the degree of deviation of the current values of diagnostic indicators from these boundaries are carried out.

Based on the obtained estimates of the degree of deviation of the generalized indicators (physiological adaptation price) in block 15 of the formation of the communicative function of deviations (as a function of operating time)

The significance of these deviations is estimated. The current level of significance of deviations is transmitted to block 16 for the formation of individual recommendations and block 22 for generating a signal to turn off the device. In block 16 of the formation of recommendations based on the analysis of the significance level of the current deviation, individual recommendations to the user are generated. These include, for example, the following recommendations:

1) to make a certain duration a break in work (passive rest),

2) take a certain duration of a break in work in combination with outdoor activities, the recommended set of breathing exercises and relaxation relaxation,

3) conduct psychophysiological testing.

The recommendations made through the control unit 10 are transmitted to the visual information generation unit 17 and displayed on a display or printer screen.

In block 22 of generating a signal to turn off the device, the significance level of the current deviation is analyzed, and if it exceeds the individual alarm threshold, a signal to turn off the computer is generated. This signal is transmitted to the actuator, which performs all the necessary operations to save the results of previous user work and operations to turn off the computer in the computer's memory.

A useful model of the peripheral heart rate sensor complex unit is made in the form of a housing 1, in which there is a board 25 carrying an optocoupler in the form of an infrared radiation source 26 and a photodetector 27, the optical lenses of which are located in the holes 2 and 3 of the housing 1. The board 25 is informationally and energetically connected with the second board 28, located in the housing 29 of the plug connector 30. On this board 28, a block circuit is implemented using well-known circuitry solutions for converting an analog signal to

digital. In this case, it contains sequentially interconnected: a low-pass filter 31, an amplifier 32, an analog-to-digital converter (ADC) unit 33, a parallel to serial code converter 34, a full code package driver unit 35, and a galvanic isolation unit 36. In addition, the block circuit has a clock generator 37 connected to the inputs of block 33 directly and to the input of the converter 34 through a frequency divider 38. The plug of the connector 30 through the socket 5 of the housing of the complex block II provides information contact of both complex blocks.

In addition, the housing 1 is equipped with a removable clamping device 39 having a portion of the clamp 40 in the area of the finger above the holes 2 and 3 of the optocoupler. At the bottom, the housing 1 is equipped with a bottom cover 41, on which (inside the body volume) an electromechanical block 42 of a traditional computer mouse is placed with the manipulator ball 43 exiting through an opening in the bottom cover.

From the board 25 and from the electromechanical unit 42, the output from the housing 1 through the hole 44 of the energy and information cables, respectively,

to the board 28, which converts the analog signal to digital, which, in turn, is connected to the socket 5 on the housing 4 through the plug of the connector 30,

to the socket 45, located on the housing 4 and used to connect the plug 46 of the connector.

A useful model of the sensor unit operates as follows. The following options for its operation (operation) are possible, as noted above, which are caused by various options for combining its two functional entities, namely, the pulse wave pick-up function (1) and the coordinate converter function (2).

1. With the simultaneous implementation of the first and second functions (pulse wave, coordinate converter), the electrical signal from the infrared radiation detector 27, located on the circuit board 25,

through the low-pass filter 31 is fed to the input of block 32 of the low-frequency amplifier.

From the output of amplifier block 32, the signal is fed to the input of ADC block 33. Upon completion of converting the analog signal to digital, transforming it in parallel parallel block into serial one and forming a complete code block in driver unit 35, the digital signal is fed to galvanic isolation block 36, the output of which is connected through slot 5 with filter 6 of the Integrated software and hardware block II.

The operation of block 33 of the ADC and block 34 of the parallel-to-serial converter is controlled by block 37 of the clock generator through block 38 of the frequency divider.

The signal from the coordinate transducer (from the electromechanical unit 42) enters the computer through the connector slot 45, which is essentially a standard ComPort.

2.When the sensor unit carries out only its 1st function, its operation with respect to the pulse wave acquisition completely coincides with the one described above in paragraph 1 ... Moreover, to ensure stable contact of the patient’s finger with lenses (in openings 2, 3 on the housing 1 ) emitter and photodetector, a removable clamping device 39 is used.

3.When the sensor unit performs only its 2nd function (only the coordinate converter), the operation of the Complex unit of the peripheral pulse sensor completely coincides with the work of the traditional coordinate converter (computer mouse). The working signal from the electromechanical unit 42 enters the computer through the plug socket 45.

The control of the execution of input operations of the pulse wave recorded by the sensor, as well as the operations of input / output of information from / to the blocks 18, 19, 24 and 42, are performed by the control unit 47 for performing exchange operations. The functional essence of this unit is equivalent to control operations that are carried out within any of the known operating systems.

The implementation of the proposed utility model of a device for dynamic screening of health status using the sensor unit utility model allows not only to carry out dynamic health screening compared to the known prototype, but also to carry it out during the entire period of the PC user (operator) operation without interfering with its work, This allows you to quickly detect early signs of overstrain in the state of the body and take appropriate measures, i.e. ceteris paribus, dramatically reduce the likelihood of erroneous PC user actions. In addition, the implementation of the proposed technical solution, contributes to the timely implementation of individual recommendations to reduce the adverse effects of PC on the health of the PC user (operator).
