The transmitter and processor can receive signals and transmit data to memory.

Such a device has limited functionality, since it does not provide an operational call for help to a patient who is in an unfavorable situation.

A known medical system for monitoring the parameters of patients in a home setting, at the workplace or in boarding houses [2], comprising a device for recording measurement results from patients and a device for transmitting measured values to a central station of the system, a device for interrogating measured values and a receiving device from an observer staff. The central station of the system is equipped with a memory for measured values and a data processing device with a comparator for comparing the measured values with the set values stored in the memory. In addition, there is an alarm supply device for generating an alarm signal and a routing device for the transit of the alarm signal to the receiving device of the personnel on duty.

The known system is quite complex in technical implementation and contains a large number of complex functional blocks, which prevents its widespread adoption.

Closest to the technical nature of the proposed design solution is a system for personal signaling for help or

a dangerous situation [3], containing a personal radio signal module, a radio signal processing device and a point for monitoring and receiving signal information and determining the location of the signal source and making a decision to provide assistance, as well as a radio signal receiving and generating a corresponding message, each located at the corresponding intermediate points having lines of a city telephone network distributed in a controlled area, connected to telephone lines for communication with a point monitoring and receiving information and determining the location of the signal source by the location of the devices for receiving the radio signal and forming a message.

The disadvantages of such a system are its structural complexity, due to the large volume of heterogeneous equipment, as well as the lack of technical means for opening the door of the room in which the helpless patient is located, which complicates quick access to it for emergency assistance.

The technical result, which consists in eliminating the noted drawbacks, is achieved in the proposed help call system, including an adverse event warning device, made, for example, in the form of a bracelet mounted on the patient’s body, mainly on the arm, and containing an alarm button, sensors of the patient’s body, a power supply unit, an information processing unit and a patient alarm transmission unit, as well as a stationary primary information processing device consisting of a receiving unit t evozhnyh patient signals, a decoder, a control unit and an execution unit, in that the actuating unit comprises a connection node of the wired telephone network, a node on a mobile communication network and the telephone communication unit with an electronic lock mounted on the door of the room in which the patient is located.

At the same time, in the notification device about an unfavorable situation, the information processing unit is made in the form of a microprocessor and an associated actuating unit, and the patient’s organism state sensors are connected to the microprocessor inputs, and the output of the actuating unit is connected to the input of the patient’s alarm transmission unit.

The technical result is also achieved by the fact that in a stationary device for processing primary information, the output of the patient alarm receiving unit

connected to the input of the decoder, the output of which is connected to the input of the control unit, the output of which is connected to the input of the Executive unit.

In addition, the achievement of the specified technical result is ensured by the fact that the electronic lock consists of a receiver for the signal for opening the lock connected via an electromagnetic actuating element to the mechanical assembly for opening the lock.

The essence of the utility model is illustrated by drawings, where:

- figure 1 shows a warning device about an unfavorable situation;

- figure 2 shows a stationary device for processing primary information;

- figure 3 presents the design of the electronic lock ..

The device warning about an unfavorable situation (figure 1) is made, for example, in the form of a bracelet; attached to the patient’s hand using a strap or other means (not shown in the drawing). The composition of this device includes a set of 1 sensors of physiological parameters: a pulse sensor 2, a motion sensor 3 and a temperature sensor 4, mounted on the patient's body (arm). In addition, a “panic” button 5 is located on the bracelet, which is used to signal an alarm to the patient. The device also includes an information processing unit 6, made in the form of a microprocessor 7 and an associated actuating unit 8, and sensors 2-4 of the patient’s body condition are connected to the inputs of the microprocessor 7, and the output of the actuating unit 8 is connected to the input of the patient’s alarm transmission unit 9 the output of which is connected with the transmitting micro-antenna 10. The functioning of the blocks and nodes of the adverse alert device is provided by an autonomous power supply source 11.

The wristband (Fig. 1) is made in a shockproof and waterproof case and is designed to transmit a coded radio signal when the user presses the “disturbing” button 5 and (or) according to the results of measuring the parameters of the “functioning” of the patient’s body with sensors 2-4.

A stationary device for processing primary information (Fig. 2) consists of a block 12 for receiving alarm signals, the input of which is connected to a receiving antenna 13, a decoder 14, a control unit 15, and an executive unit 16 consisting of a node 17

communication over a wired telephone network, communication node 18 over a mobile telephone network and communication node 19 with an electronic lock, and transceiver antennas 20 and 21.

The output of the patient alarm receiving unit 12 is connected to the input of the decoder 14, the output of which is connected to the input of the control unit 15, the output of which is connected to the input of the executive unit 16 connected to the antennas 20 and 21.

A stationary device for processing primary information is designed to provide reception of a radio signal from a wearable bracelet and to carry out a sequential set of numbers of subscribers stored in the memory and the issuance of relevant information to each of them.

Executive unit 16 is designed for communication via STS (fixed telephone network) and / or via MTS (mobile telephone network) and to ensure dialing of a subscriber number, as well as transmitting a request for servicing a call received over the telephone network. In addition, the Executive unit is designed to provide transmission of transmitted and received information through the built-in speaker (not shown in the drawings).

The electronic lock 22 (figure 3) consists of a receiver 23 of the signal for opening the lock, the input of which is connected to the receiving antenna 24, and the output through the electromagnetic actuating element 25 with the mechanical assembly 26 of the opening of the lock.

The functioning of the nodes and elements of the electronic lock 22 is provided by an autonomous power supply unit 27.

The help call system serves to transmit an “alarm” message about the distressed state of a person who is unable to independently report this by telephone to his relatives and / or medical and rescue services. For older people, this situation can be caused, for example, by a fall with injuries affecting active activity.

The notification is initiated by a person who does not have the physical ability to independently make a phone call by pressing the “disturbing” button 5 of the wristband or fixing by the sensors 2-4 included in the kit of the same wristband, disabilities of his body. In this case, the system automatically dials and transmits a short voice message to the phone numbers to which the patient’s system is configured.

The system operates as follows.

After connecting and configuring, the system is in standby mode, when the wearable bracelet is turned off, and the stationary device for processing primary information is in standby mode.

In the event of an emergency (a sharp deterioration and the physical impossibility of calling for help), the patient presses the "alarm" button 5.

Pressing the "panic" button 5 for 3 seconds, accompanied by a short beep, leads to the inclusion of the block 9 for transmitting alarm signals of the patient 9, which transmits an encoded signal through the antenna 10. The issued signal is encoded in order to reduce the likelihood of false positives of a stationary device for processing primary information (figure 2) from random interference,

Release of the button 5 leads to the shutdown of block 9, but only after completion of the issuance of the encoded signal.

The signal received by the stationary primary information processing device is decoded by the decoder 14 to identify the received signal. False signal interference is ignored. For a reliable signal by the control unit 15, a program is launched to ensure consecutive dialing of the numbers of subscribers stored in the microcontroller (included in the control unit 15 and not shown in the drawing) with the transmission of a voice message corresponding to the called number of the subscriber. If the subscriber number is busy, the program proceeds to dial the next subscriber number. A return to an attempt to connect to a previously occupied number is made after issuing a voice message to the subscriber with whom communication has been established.

The issuance of messages to the telephone network by communication nodes 17 and 18 is carried out until all relevant messages have been transmitted to subscribers from the stored list.

Upon receipt of a telephone call to the patient, if this call occurred after pressing button 5, the stationary primary information processing device (Fig. 2) switches to the answering machine mode and transmits to the caller a standard voice message about the inability of the user to answer the call because of his physical weakness. Time spent

stationary device in this mode - from the moment you press button 5 to pick up the handset from the telephone.

When establishing a connection with the called subscriber, the stationary device for processing the primary information of the system transmits received and transmitted messages through the built-in speaker (not shown in the drawing) to inform the user about the fact of sending and receiving an alarm message.

The system configuration consists in sequentially dialing the telephone numbers of subscribers with whom communication should be established, and setting the voice messages corresponding to these numbers.

Since the system contains an electronic lock 22, which ensures the opening of the front door when receiving a command from a stationary primary information processing device via a radio link (Fig. 2), this eliminates the need to crack the front door, which speeds up the assistance and eliminates the need to restore or replace a broken door.

Upon receipt of a signal to open the lock from the antenna 24 from the antenna 24, the electromagnetic actuating element 25 is connected to the mechanical opening 26 of the lock, which ensures unhindered opening of the door by an ambulance doctor, rescue personnel or any of the notified persons.

This state of the lock 22 is blocked after the first opening of the door until the next pressing of the "alarm" button 5.

The proposed assistance call system is implemented on available technical means of digital and analog equipment using an electromagnetic element with mechanical traction for locking, associated with the locking mechanism of the door lock. The wearable bracelet is made of plastic or a metal spring-loaded ring, with an “alarm” button located on it, sensors and a miniature printed circuit board with electronic elements.
