Description

The proposed utility model relates to the field of medicine and medical technology, in particular, to apparatus for recording physiological parameters of an organism using sensors worn by the patient and can be used for remote diagnosis of acute coronary insufficiency, cardiac arrhythmias, and for monitoring blood glucose levels as in one the patient, and in large groups of patients, as well as to call emergency care and prompt medical advice.

Biomedical complexes are known for measuring the physiological parameters of a person using sensors worn by the patient, including for taking an ECG of one or several leads, for measuring blood glucose, for measuring blood pressure in a hospital, or outpatient, transmission of these data via GPRS channels to a data collection server and the formation of a database of values of physiological parameters of patients in order to monitor physiological parameters and remote diagnosis of the disease cardiovascular system and / or determination of the current level of glucose in the blood of patients with diabetes mellitus (see O.S. Medvedev, O.B. Kerbikov, Telemedicine: future technology or the ability to increase the level of medical care today. // Computer technologies in medicine. No. 2, 1997, pp. 88-89.). The procedure for measuring physiological parameters, including the application of electrodes, is performed by the patient himself and the data from the sensor is transmitted at the command of the patient through a smartphone or PDA.

Diagnostic complexes are also known in which electrodes and other sensitive elements of physiological parameters sensors are fixed on the patient’s body using the so-called LifeShirt medical diagnostic shirt. In this case, round-the-clock monitoring of various functional indicators (including ECG and blood pressure) is possible with recording on a portable recorder on the patient’s belt and subsequent data transfer via the Internet to a special site of the medical center, where the data are analyzed by doctors.

Despite the electrodes and other sensitive elements of the sensors sewn into the fabric, the shirt is easy to wash and can be used both at home and at work (Dorn C., Merrell R. Remote telemonitoring // Medical Bulletin, No. 8 (171) March 2001 .). However, the analysis of data received by doctors from the server can be delayed, which can lead to an unfavorable outcome in the patient's condition, including fatal. In addition, in the acute state, the patient may not be able to reach the smartphone, or other mobile platform from which data is transmitted to the server and / or manipulate the data transfer to the data collection server. Data transmitted over the Internet should be encrypted to ensure confidentiality of information about the health status of patients, to reduce the number of transceivers, it is necessary to ensure switching of signals from sensors of physiological parameters and transmit alternately from one transceiver.

The objective of the proposed biomedical complex is to increase the effectiveness of remote monitoring of the physiological parameters of a person on an outpatient basis and reduce the time required to provide the patient with emergency care, or individual consultation, as well as ensuring the confidentiality of information transmitted to Internet channels.

The problem is solved in that in the well-known biomedical complex for remote monitoring of physiological parameters, containing sensors carried by the patient, including ECG sensors of one or several leads, blood glucose sensors, blood pressure sensors, a mobile platform for transmitting physiological data via GPRS channels, a data collection server, the complex additionally contains an emergency call block, a switch for sensor signals, which provides alternate connection of sensors to the receiver The transmitting device, in addition, a program module has been introduced into the smartphone of the on-duty or family doctor, which, in the event of an alarm about the emergency condition of the patient, provides a sound signal to the doctor's smartphone and an automatic request to the data collection server to obtain records of the physiological parameters of the patient, who made the alarm call, which provides quick viewing of database records, when the doctor is outside the hospital and out of contact with the computer terminal of the doctor on duty, edeny as program modules patient smartphone providing encryption of transmitted data, recording and monitoring of individual indicators sinus arrhythmia (e.g., 50, as the upper limit and 20 as lower

limit), recording and monitoring of individual indicators for the maximum and minimum acceptable values of blood glucose, as well as systolic and diastolic pressures, beyond which the smartphone gives an alarm to the patient and automatically transmits the received physiological data to the data collection server and automatically makes a call to the duty or family doctor, who take measures to ensure emergency care in case of outpatient monitoring of the patient, or conduct an urgent contact with him sultation, in addition, the patient can use a portable emergency call unit equipped with an “alarm” button and which through the blue tooth channel will transmit an alarm signal to a smartphone located within a radius of 10 m from the patient in case the patient loses mobility and / or difficulty in handling a mobile platform, while the smartphone will send the appropriate signal to the data collection server, as well as an alarm to the on-duty or family doctor, software modules are also introduced that provide data decryption, to the doctor’s smartphone and to the server data collection.

Figure 1 shows a block diagram of a biomedical complex for monitoring physiological parameters.

The biomedical complex for monitoring physiological parameters (Fig. 1) includes sensors of physiological parameters 1a ECG sensor, 1b - blood glucose level sensor, 1c - blood pressure (BP) sensor, or a larger number of sensors that record data from electrodes , or other sensitive elements in contact with the patient’s body, or non-contact, a 2-switch sensor signals, providing alternate connection of sensors to a transceiver device, 3-transceiver device for receiving data from sensors of physiological parameters and data transmission to the patient’s mobile platform via bluetooth, sound channel, or in another way, including using electric or fiber optic cables, a 4-transmitter-receiver station of a cellular operator, 5-smartphone, or other a patient’s mobile platform, a 6-smartphone, or another mobile platform of the on-call or family doctor, as well as an emergency call block, a data collection server containing a database management system (DBMS), as well as one or more terminals of the emergency Connecting via a computer network to a data collection server.

The proposed utility model meets the criteria of “novelty” and “inventive step”, since in the process of conducting patent information research no sources of patent and scientific and technical literature discrediting novelty have been identified

variants of the proposed device, as well as technical solutions with essential features of the variants of the claimed device.

Data is collected on a server with a 2.6 GHz processor (AMD Opteron), RAM, 1024 GB, with a disk subsystem, 3 × 300 GB (RAID 5, SATA). Cashe DBMS provides the ability to store data for 350 thousand patients. The patient’s and the doctor’s or family doctor’s smartphones (Nokia E51) have software that supports the Series 60 v.3 platform (Symbian 9.x OS), a mobile telemonitoring client that provides the ability to register the following physiological parameters (if appropriate equipment is available):

1. ECG (1 lead),

2. Blood sugar.

3. Blood pressure;

4. Pulse (measurement at a single point in time);

5. Pulse (continuous measurement);

6. Blood oxygenation;

or an additional 1-2 ECG leads instead of one or two data above the parameters.

Smartphones transmit data over the GPRS channel. In addition, the doctor’s smartphone has software modules that receive data from the data collection server via the GPRS channel and a decoder, as well as a software module that, in the event of an alarm about the emergency state of the patient, provides a sound signal to the doctor’s smartphone and automatically requests to the data collection server to obtain records of the physiological parameters of the patient who made the alarm call. The data collection server has a register of patients (up to 350,000 patients), for each of which an electronic medical history is kept. The registry allows the creation and viewing of medical records, as well as viewing data received from the terminal of the doctor on call and from the mobile platforms of doctors. Record in the register of data for the removed physiological parameters is carried out automatically, in the medical history of the corresponding patient in accordance with the identifier of the patient’s mobile platform, which is automatically indicated when sending the data. The doctor on duty from his terminal can create medical history for new patients and close existing ones. The cardiological sensor IKRZ-1 registers one ECG lead and transfers the data to the patient’s smartphone via the sound channel. Overall dimensions: 80 × 40 × 20 mm, weight 60 grams. In the absence of sensors capable of sending data to a mobile

the patient’s platform, it is possible to manually enter the values of physiological parameters measured by the patient with the help of a glucometer, tonometer and other instruments in a mobile platform. At the same time, the mobile platform provides further automatic transfer of manually entered data via the GPRS channel to the server. The emergency call block is a device for delivering a call signal to the patient’s mobile platform. For example, a Bluespoon AX2 headset that supports the Bluetooth 1.2 protocol. Standby time of at least 500 hours. Pressing the “NOT” button activates the voice dialing function, while the “alarm” signal issued by the voice activates the software modules of the patient’s mobile platform, which ensures that the mobile platform sends the corresponding signal to the data collection server, as well as the alarm to the doctor on duty or family. A Bluetooth headset is attached to the patient’s ear and does not restrict movement. The range is up to 10 m. When using the Bluespoon AX headset, the range is increased to 30 m. An alarm is also generated when one or several physiological parameters go beyond the intervals set in the program of the mobile platform of the patient. For example, an individual indicator of sinus arrhythmia, an individual indicator of acceptable values of blood glucose, as well as an individual indicator of systolic and diastolic pressures.

The device works as follows: at the time agreed upon by the doctor, with the agreed frequency of the procedure, or on his own initiative, the patient imposes electrodes of the ECG sensor and / or sensitive elements of sensors of other physiological parameters on his body. The doctor recommends the doctor sets the exposure time (the time during which the physiological parameter is recorded). Then the patient takes the position recommended by the doctor and presses the button on the smartphone (mobile platform), which launches the program for analog-to-digital conversion of the signal, recording data in digital form into the RAM of the smartphone (mobile platform), encrypting it and transmitting it to the address entered into the program on data collection server. Data is transmitted via the GPRS channel of the mobile operator. If it is necessary to simultaneously record several physiological parameters, sensors of the corresponding parameters (up to six or more) are installed. A smartphone (mobile platform) processes and transmits data to a server. When working in sequential mode, the number of parameters removed increases, for example, sequential removal of signals from several ECG leads is possible. When using a switch for sensor signals, it is also possible

serial connection of physiological parameters sensors to one analog signal transmitter on a mobile platform. After the patient presses a certain button on the keyboard of the smartphone (mobile platform), the computer program of the latter performs an analysis of the physiological parameters matching the established individual intervals of acceptable values and transmits data via GPRS to the data collection server. When one or several physiological parameters go beyond the established individual intervals of acceptable values, data transfer is accompanied by an alarm for the patient, doctor and for the program for recording data in the patient registry, which will mark the received signal in the registry line, where the patient’s last name is marked. Alarms for the patient and the doctor are accompanied by the sound of a telephone. The data received on the smartphone (mobile platform) and on the server is automatically decrypted by the decryption software module.

In the event of a sharp deterioration in the condition, the patient can use a portable emergency call unit equipped with an “alarm” button and which will transmit an alarm via blue tooth to a smartphone located within a radius of 10 m from the patient in case the patient loses mobility and / or difficulty in handling with a mobile platform, while the smartphone will send the appropriate signal to the data collection server. A doctor can view data from the doctor’s on-call terminal, or from his smartphone (mobile platform), or across the entire patient registry, or from a group of follow-up patients by sequentially viewing medical records.
