Description

Device for monitoring human condition

The utility model relates to the field of radio electronics and can be used to monitor a person’s condition, mainly in critical situations (when the driver of a moving vehicle falls asleep, the patient worsens, the offender attacks, etc.).

A device for monitoring a person’s condition, comprising a continuous or discontinuous test signal of a radio wave range connected to a power source, and a test signal receiver, an information processing unit, and an alarm generation unit located outside the eye of a controlled person, are connected in series, the transmitter and receiver being a test -signals are mutually arranged so that at least one eye eyelid of a controlled person during its movement during blinking partially or completely erekryvalo test signal path, said elements can be placed, for example, eyeglass frame, worn on the monitored person (US 5,402,109 A, 1995).

In this device, in a continuous or intermittent mode along the outer surface of the eye of a controlled person, a test signal of the radio wave range is emitted. The eyelid modulates the intensity of the test signal during blinking.

However, such a device is ineffective. This is due to the fact that the possibility of the appearance of false alarms is not eliminated. for example, with sudden movements controlled

person. It is only envisaged to detect sleep with the closed eyelids of a controlled person, which does not allow, for example, to detect a state of loss of consciousness in which the eyelids can remain open. The placement of device elements external to the eye of a controlled person requires their precise adjustment both during calibration of the device and during its operation.

Of the known devices, the closest to the proposed device is a device for monitoring the condition of a person, containing a contact (ophthalmic) lens placed on the human eye, the state of which is monitored, made in the form of a microchip and equipped with an autonomous power source of at least one emitter of a test signal, the frequency of which selected in the radio frequency range, located in the peripheral part of the contact lens, and serially connected to the main receiver of the test signal, located at th to the emitters of the test signal to enable the interruption of the emitted test signal at blinking eyelid, the information processing unit and the alarm generating unit (US 6,087,941 A, 2000). The main receiver of the test signal and the blocks for processing information and generating an alarm are placed outside the eyes of the controlled person, for example, on a body opposite the head of the driver of the vehicle.

This device is also not effective enough. The test signal is open to external influences, which reduces noise immunity. Placing most of the elements outside the eye of a controlled person does not provide stealth, which is especially important, for example, when attacking a controlled person by an attacker. It is possible to detect only a state of sleep or falling asleep of a controlled person, a decrease in the frequency of blinking (which precedes, for example, loss of consciousness) and the absence of blinking with constantly open eyelids does not

being analyzed. Not always the test signal falls on the main receiver of the test signal, for example, due to unexpected sudden movements of the head or the characteristics of the blinking of a particular controlled person, since there is only one such receiver of the test signal. Finally, the device does not contain elements that allow you to transmit an alarm signal at a distance, which does not allow you to quickly monitor a person’s condition and limits the possibility of external assistance.

The problem solved by the utility model is to create a device for monitoring the condition of a person devoid of the disadvantages of the prototype. The technical result provided by the utility model is to increase the efficiency of the device by increasing the objectivity, noise immunity, stealth and speed of control of such a device, as well as increasing its operational reliability.

This is achieved by the fact that the device for monitoring the human condition, containing a contact lens placed on the human eye, the state of which is monitored, made in the form of a microchip and equipped with an autonomous power source at least one emitter of the test signal, the frequency of which is selected in the radio frequency range, placed in the peripheral part of the contact lens, and in series connected to the main receiver of the test signal. located in relation to the emitters of the test signal with the possibility of interrupting the emitted test signal when the eyelid blinks, the information processing unit and the alarm generating unit contain additional test signal receivers made in the form of microchips, the number of emitters and receivers of the test signal chosen the same, the test signal receivers and the information processing unit are located in the peripheral part of the contact lens, and the test signal emitters and receivers form pairs, in each of which emitter and receiver of the test signal are located

with the possibility of interrupting the emitted test signal when the eyelid blinks on its inner surface, while the alarm generating unit consists of an alarm transmitter made in the form of a microchip and placed in the peripheral part of the contact lens, and an alarm transceiver located outside the eye a person at a distance from him, selected from the condition of stable radio communication between the transmitter and the transceiver of the alarm signal. The emitters and receivers of the test signal, the information processing unit and the alarm transmitter can be placed on the surface of the contact lens. The emitters and receivers of the test signal, the information processing unit and the alarm transmitter can be placed inside the contact lens. The alarm transceiver can be made in the form of a cell phone. Autonomous power supply can be made in the form of a solar battery. In each pair between the emitter and the receiver of the test signal can be placed a waveguide. The emitter and receiver of the test signal in each of the pairs can be combined. The information processing unit and the alarm transmitter can also be combined.

The proposed utility model is illustrated by drawings, which depict:

figure 1 is a structural block diagram of a device for monitoring the condition of a person;

figure 2 is an example of the placement and interaction of elements during the propagation of the test signal emitted along the inner surface of the eyelid (conventionally shows one pair of emitter-receiver of the test signal);

in Fig.3 is an example of the placement and interaction of elements during the propagation of the test signal emitted in the direction of the eye eyelid (one pair of emitter-receiver of the test signal is conventionally shown).

in the proposed device for monitoring human condition, all operations with test signals are carried out between the eyeball (including the pupil 1 and the iris 2) and the eyelid 3. The emitted test signal in this case has a direction 4 along the inner surface of the eye eyelid 3 or . The proposed device contains emitters of a test signal 5, the main 6 and additional 7 test signal receivers, an information processing unit 8, an alarm transmitter 9, made in the form of microchips, and an autonomous power source 10 connected to the above elements, which can be performed, for example, in the form of a solar panel. The wavelength and energy of the test signal are selected in such a way as not to interfere with the eye of a controlled person and not to produce harmful effects on his organs. The listed elements are placed on the surface or inside the contact lens 11 mounted on the eye of a controlled person in its peripheral part, so as not to interfere with the eye and not irritate the inner surfaces of the eyelids 3. Set of elements 5, 6, 7, 8, 9, 10 or 6, 7, 8, 9, 10, or in another embodiment, combinations can be made in the form of a single microchip. The number of emitters of the test signal 5 and the number of all receivers of the test signal 6, 7 are chosen the same. They form pairs, the number of which is determined by the condition of complete or at least significant overlapping by the inner surface of the eye eyelid 3 of the corresponding part of the contact lens I. Mostly their number is two or three pairs (in the extreme case, their number is unity, as in one of the options prototype devices). The emitters 5 and receivers 6, 7 of the test signal in each pair are located on the contact lens 11 (outside or inside it) so that it is possible to influence the inner surface of the eye eyelid 3 on the path 4 of the test signal. The device also contains

alarm transceiver 12. for example, in the form of a cell phone located, for example, in the pocket of the clothes of a controlled person.

Depending on the choice of the direction 4 of the test signal, toward the inner surface of the eye eyelid 3 or along it, the functioning of the proposed device has its own characteristics.

In one embodiment of the proposed device, which is simpler (Fig. 3), the emitters of the test signal 5, for example, in the amount of three (in Fig. 3, the second and third emitters of the test signal 5 are not shown for simplicity), form at their output test signals, which are mainly a sequence of pulses emitted, in the direction 4 to the inner surface of the eye eyelid 3. When the eye eyelid 3 is open, the test signals, or at least most of them, go into the surrounding space and are scattered there. When the eyelid 3 is closed, test signals are reflected from its inner surface and enter the corresponding main 6 and additional 7 test signal receivers (in Fig. 3, test signal receivers 6, 7, as well as information processing unit 8 and an autonomous power supply 10, not shown for simplicity). In the process of normal blinking, the inner surface of the eye eyelid 3 periodically, with a frequency of normal blinking, reflects the test signal. Detected mainly by 6 and additional 7 test signal receivers, they enter the information processing unit 8, in which, in accordance with the specified algorithm, the modulation frequency is analyzed and compared with the normal frequency. At the same time, the algorithm of its operation takes into account the probability that, for example, one of the test signals did not reflect from the eye eyelid 3, for example, due to the peculiarities of human blinking. In the case of a normal blinking process, there is no signal corresponding to

MshyP

the alarm transmitter 9 does not generate and does not transmit an alarm signal. In the case when the monitored person is, for example, in a state of drowsiness, the blinking frequency becomes abnormally high and the information processing unit 8 gives the corresponding signal to the alarm transmitter 9, the output of which an alarm occurs, for example, a radio signal that is transmitted to the transceiver of the alarm 12. The transceiver of the alarm 12 generates, for example, an acoustic signal that interrupts the willow. In the case when the controlled person is close to a state of loss of consciousness (fainting), the frequency of blinking becomes abnormally low, and an alarm signal is also generated in a similar way. In the event that a sudden state of sleep, loss of consciousness, or intentional closing of the eye (s) of a controlled person who is in an anxious position (for example, when an offender attacks him or other people nearby to secretly give an alarm) is made, when closed eye eyelids 3 test signals begin to arrive in the main 6 and additional 7 test signal receivers for a long time, which also leads to the formation of an alarm. In the case when a sudden loss of consciousness occurs with open eyelids 3, the test signals cease to be received in the main 6 and additional 7 receivers of the test signal, which also, due to the specified algorithm of the information processing unit 8, ensures the formation of an alarm.

In this case, the transceiver of the alarm 12, for example, in the form of a cell (mobile) phone can transmit the alarm over a considerable distance, for example, to the rescue service. At the same time as an alarm, service information can be transmitted that allows you to identify a controlled person who needs help, including about a group

blood, intolerant drugs, etc. If the cell phone is equipped with a location function (for example, has a built-in GPS receiver), then information about the location of the person in need can be transmitted. When using Bluetooth technology as a means of transmitting an alarm signal, it is possible to return to a controlled person a secret signal that information has been received from him and, for example, the corresponding group of rescuers has been sent to the scene.

In another embodiment of the device for monitoring the human condition (Fig. 2), emitters of the test signal 5 generate test signals in a similar way, but in the direction 4 along the inner surface of the eye eyelid 3 to the corresponding receivers of the test signal 6, 7, mainly along the waveguides 13 , for example, made two-layer (in Fig. 2, for simplicity, only one emitter of test signal 5 is shown, one waveguide 13 and additional emitters of test signal 7 and eye eyelid 3 are not shown). In the described example of implementation, the information processing unit 8 and the alarm transmitter 9 are made combined in the form of one unit 14. During normal blinking, the inner surface of the eye eyelid 3 periodically contacts the external surface of the waveguides 13. With this contact, the refractive index (and, therefore, the reflection coefficient ) of the outer layer of the waveguides 13 is changed in such a way that, for example, the conditions for total internal reflection in them are violated and the test signals partially or completely go beyond the wave limits gadgets 13, without falling into the respective receivers of the test signal 6, 7. Thus, the modulation of the intensity of the test signals with a blinking frequency. Moreover, at the device output, as in the previous implementation example, an alarm signal is not generated. In the case when the controlled person is in a state of drowsiness or close to loss of consciousness.

at the output of the alarm transmitter 9, in this case, block 14, an alarm is generated. In terms of alarm transmission, the operation of the described embodiment of the device does not differ from the operation of the device according to the first implementation example.

A device for monitoring a person’s state in accordance with a utility model has higher efficiency compared to known analogous devices by increasing the objectivity, stealth and speed of monitoring, as well as increasing its operational reliability.
