Description

1. The technical field to which the invention relates

The invention relates to applications for smartphones and cellular communications.

2. Technology level

Devices are known from the prior art, for example, fitness bracelets (F / W) of the Xiaomi Mi Band type with the Mi Fit application, smart watches (S / W) of the Apple Watch type and other smart bracelets. As a second example, document RU 2567271 can be cited, which shows a method for rapid assessment of the electrical stability of the heart. This document was taken as the closest analogue.

Description of the fitness bracelet

A fitness tracker or fitness bracelet is a compact wearable gadget designed to accurately monitor a person's physical activity. These are versatile and multifunctional devices designed for:

измерения колебаний давления и пульса;

measurement of pressure and pulse fluctuations;

подсчета пройденных шагов, преодоленных километров;

counting steps taken, kilometers covered;

контроля за качеством и продолжительностью сна;

monitoring the quality and duration of sleep;

контроля расхода калорий;

control of calorie consumption;

мониторинга физической активности (бег, ходьба, плаванье, велопрогулки и т.д.);

monitoring physical activity (running, walking, swimming, cycling, etc.);

получение уведомлений со смартфона (о CMC, сообщении в мессенджерах и звонках);

receiving notifications from a smartphone (about CMC, messages in messengers and calls);

получения спортивных оповещений и рекомендаций.

receiving sports alerts and recommendations.

For all analytical information to be correct, basic information about the owner is entered into the smartphone (tablet) application before using the bracelet. This includes indicators such as age, weight and height, gender.

The technology behind the heart rate monitor is called photoplethysmography. It involves the use of green LEDs that emit light and detectors that record the level of its reflection. When the heart contracts, blood pressure increases and capillary blood flow increases. As a result, more light emitted by the LED is absorbed, which is recorded by the detector. Based on the information received, the pulse is determined.

In fitness bracelets with the function of measuring pressure, special sensors are installed, consisting of piezoelectric elements. The essence of these sensors is that under the influence of pressure exerted on them, they generate electricity. Thus, the pulse wave from the human wrist is converted into electronic signals of the corresponding magnitude, which are sent to special software. In this software, the signals are processed and presented in the form of numbers familiar to us. The result will be displayed on the device display or in the application.

3. Disclosure of the essence of the invention

System objectives and the delivered result.

One of the advantages of F / B is the convenience of monitoring a person's health status, such as pulse and blood pressure. But the disadvantage of such a system is that for a certain state of health of the user, this information is very important, but he cannot fulfill all the recommendations necessary for this condition, because at this moment he needs help from outside.

Thus, the object of the claimed invention is to eliminate the disadvantages of the prior art.

The result, which the claimed invention is aimed at, is to diagnose the pulse (pressure) of a person and, in case of suspicion of a critical health condition (CSH), notify him and, if necessary, his relatives using a modified application for a fitness bracelet - "Grandma's iPhone".

Description of the system operation.

The claimed system works as follows (see Fig. 1). The smartphone (pos. 1) receives signals from the F / B sensors (pos. 2) that control the cardiovascular system (proz. 3), which are processed in the modified application "Grandma's iPhone" (pos. 4). In the event of an emergency, for example, a pre-stroke state, the application takes a number of measures to help a person, in extreme cases, an independent voice call is made to another user of this application specified in the settings, for example, a close relative (controlling subscriber No. 2) (item 5) ...

Description of the critical condition.

A pre-stroke state is a group of specific symptoms, the appearance of which may indicate the approach of a vascular catastrophe in the brain. It can take three to six hours from the time the clinical signs appear to the development of irreversible measurements in the brain.

Stroke is of two types, hemorrhagic (cerebral hemorrhage) and ischemic.

Hemorrhagic stroke can occur if a person's typical blood pressure was around 150/100 mm Hg, but rose sharply to readings of 220/150 mm Hg.

Pressure indicators for ischemic stroke - 200/100 mm Hg. up to 250/180.

Symptoms of a microstroke:

- Increase in systolic (upper) blood pressure (BP) readings by 10-15 units in comparison with normal;

- Dizziness. Major stroke symptoms:

- HELL increases by 40 ... 50 units.

- The heart rate (pulse) also changes.

"For the period from 2008 to 2016, the primary morbidity rate of the adult population with acute cerebrovascular accident (stroke) increased by 24.8% and is 355.6 per 100 thousand people," the Ministry of Health of the Russian Federation said in a statement. "The mortality rate for adults in 2016 compared with 2008 decreased by 45% and amounted to 123.0 per 100 thousand population." The risk zone includes mainly citizens over working age (women 55 years and older, men 60 years and older). However, earlier, the Minister of Health of Russia, Veronika Skvortsova, reported that, in general, the stroke is rapidly getting younger, and young people of 20-30 years old are already at risk.

4. Implementation of the invention

The technical result is achieved due to the operation of the application according to a certain algorithm, as a result of which a new function appears - "Emergency call to relatives" (EVR) (see Fig. 2).

The claimed technical result is fully achieved by a set of features of an independent clause of the claimed system formula, namely, by adding a new ability to the fitness bracelet application, which links the phone function - a voice call, with the fitness bracelet function - health monitoring.

5. Brief Description of Drawings

6. Result

The result of this invention is:

1) Reducing mortality;

2) Reducing disability;

3) Timely notification of relatives.

7. Conclusion.

Thus, it can be understood that the proposed system is capable of:

- detect KSZ

- signal a suspicion of KSZ

- inform about first aid

- determine the location

- carry out data transmission over the Internet

- make an independent voice call, i.e. without user intervention, via a cellular network.

The technical result to which the claimed invention is directed is to determine and inform about a critical (pre-stroke) condition. This means, timely assistance, from the time of the appearance of clinical signs, to the development of irreversible measurements in the brain, if assistance is not provided during the first 3 ... 6 hours.

The claimed invention is new, since the totality of its features is not known from the prior art, and, accordingly, meets the “novelty” requirement of patentability.

The claimed invention meets the condition of patentability "industrial applicability", since it can be created in modern industry.

Although the present invention has been disclosed with reference to preferred embodiments thereof, this is not intended to limit the present invention, those skilled in the art may modify and implement the present invention without departing from the spirit and scope of the invention, hence the scope of protection of the present invention. invention shall be governed by the scope specified in the claims.
