Description

The utility model relates to medical equipment, namely to systems for the remote transmission of biomedical data, measured by the physiological parameters of the patient’s condition with appropriate devices, and can be used for remote diagnostics, assessment of the patient’s condition, and especially when providing assistance in emergency situations in general medical practice, at the scene of the incident, during the transportation of the injured, in outpatient clinics, clinics, hospitals of various profiles, military medical units, including stnosti, in remote locations and difficult terrain.

Biomedical systems are widely known, including the principle of remote transmission of biomedical data, in particular, an electrocardiogram, of a patient.

There are known systems providing for the transmission of an electrocardiogram (ECG) through the networks of GSM mobile operators in CSD mode (digital data and fax mode), or in the voice channel of a GSM network or landline telephone lines (an analog signal of special modulation from an electrocardiograph is input to the telephone microphone). In this case, ordinary household telephones of the GSM standard or household corded telephones are used. ECG transmission is carried out by direct dial-up (dial-up connection) from the transmitting telephone to the receiving (O.S. Medvedev, O.B. Kerbikov, Telemedicine: future technology or the ability to improve the level of medical care today. // Computer technologies in medicine. No. 2, 1997, pp. 88-89).

There are known systems that have specialized modems as part of their equipment that provide ECG data transmission in the data and fax mode of the CSD channel of a GSM network or a wired communication line (description of patent for invention RU 2283511, G06F 19/00 (2006.01), 12/06/2001) .

Known systems for transmitting ECG data through handheld computers, laptops, smartphones, "tablets", while the file with ECG information is transferred to the listed funds physically by transfer method via a flash card or via Bluetooth. In the latter case, an additional script program is installed in the household transmission medium, which provides data transfer in the GPRS channel. So, for example, utility model RU 82536, АВВ 5/00 (2006.01), 05/10/2009, adopted as a prototype).

Known systems for the transfer of biomedical data have serious shortcomings that the end user, a medical professional or a patient, discovers only during operation. The main disadvantages of the known systems are as follows.

Lack of automation of the process of information transfer, serious dependence on the human factor, both on the transmitting and receiving sides. The process of transmitting data from the ECG consists of a large number of non-automated, sequential operations: dialing the telephone number of the receiving party, waiting for the operator’s response, waiting for the transmission time interval while holding the handset next to the ECG device, voice dialogue with the personnel on the receiving side about the quality of the received ECG and filling out a patient card, etc.).

Low noise immunity. The dependence of transmission methods on the quality of telephone lines on the transmitting and receiving sides seriously reduces the noise immunity of the information transmission process and, as a result, the reliability and efficiency. In known systems, methods for transmitting biometric data in a CSD channel or a voice channel of a GSM network are similar to sending fax messages using fax.

Low transmission bandwidth. At the time of the transmission of information, the dispatcher’s receiving line is busy for other subscribers (the handset on the receiving side is off-hook). If the signal from the electrocardiograph during the transmission does not reach the addressee in the proper quality and volume, then the communication session will have to be repeated, while the communication channel may already be taken by another subscriber or voice call.

The absence of automatic means of monitoring the integrity of the transmitted information and its quality, automatic methods of re-sending information when the connection is disconnected, and automatic buffering of information seriously reduce the applicability of the means of transmission in a mobile application, for example, in an ambulance or data transfer from a wearable ECG. For these cases, data transmission over the GSM network often becomes simply impossible or very time-consuming. When using a GSM standard cellular network, dips during speech, occasional disconnections, and the inability to make a connection may occur periodically. It’s enough to imagine the operation of sending a fax from an ambulance to the call center while the car is moving or when it is parked from a zone of poor reception of telecom operators (communication is unstable, the signal strength of base stations is low, the reflection from local objects (echo effect), etc. ) In other words, data transfer for the above methods in the mobile application is possible only for ideal cases, which are unlikely in real life.

A serious drawback of these means of transmitting ECG information is also the lack of built-in, automatically used backup communication channels, which limits the applicability of the product in a mobile use case.

The use of household telephones cannot guarantee the quality of transmission of special information. In the production of household communications, manufacturers solve other goals - ensuring conversation comfort (GSM communication failures are artificially camouflaged by repeating previous speech fragments, implementing “comfortable” noise in pauses of speech, which is not noticeable or pleasant to the human ear and not relevant for data transmission in fax mode in the speech channel). The use of non-specialized means of transmitting information cannot guarantee the quality, integrity and reliability of the transmitted information.

High communication costs when transmitting data in dial-up mode.

The objective of the utility model is to eliminate the above disadvantages.

EFFECT: increased reliability and efficiency of data transmission and cost reduction.

The technical result is achieved by the fact that in a medical telemetry monitoring system including instruments for measuring physiological parameters of a patient’s state, a transceiver of measured data via GPRS channels and a data collection server, a transceiver is configured to automatically receive and transmit digital data files to server upon the moment of supply and removal of power from devices, data buffering in case of disconnection and automatic retransmission of data until confirmation Niya their server integrity.

Instruments for measuring physiological parameters can be equipped with an RS-232 port, or an analog output, and the transceiver consists of a hardware module for storing and transmitting data in an Ethernet or GSM network to a data collection server and wireless modules for transmitting data from devices to a hardware module, at the same time, wireless data transmission modules are made for MiWi or ZigBee or Bluetooth standard networks and are equipped with an RS-232 interface or an analog input for connecting devices.

The transceiver can be made in the form of a portable module with the ability to place on the patient’s body and transmit data via the GPRS channel of the GSM network, as well as through the channels of at least two GSM network operators.
