They are also capable of application within the hospital environment for the transmission of data from the rooms of the patients to the control center, with the consequent saving of wiring and improvement of patient mobility.

  • the SM also has a GPS module (Global Positioning System) that allows the positioning of the Mobile System via satellite, using radioelectric triangulation procedures. In this way, when desired, you can quickly know the location coordinates, and therefore its location, of the Mobile System, and obviously of your associated patient.
  • GPS module Global Positioning System
  • This module is small in size, low consumption and with an integrated antenna, independent of the main communications antenna.
  • the Mobile System control module controls the activation of the GPS module in order to locate the patient only when necessary. Consequently, the update of the position by GPS meets a criterion of optimization of consumption, being carried out with the highest

  • the functional control of the SM is carried out by means of a microprocessor system, equipped with an intelligent software system, based on an expert system and on neural networks, for the analysis and processing of the electrocardiographic signal, discriminating between a plurality of possible predefined cardiac pathologies.
  • This system allows to detect one of these possible predefined cardiac pathologies by means of an algorithm of detection and recognition of heart disease, in this way the Mobile System only transmits to the server center when it detects a cardiac pathology.
  • This algorithm has several levels of detection that can be configured from a Control Center, from where the different types of cardiac pathologies to be monitored particularly in each patient are also configured.
  • the Mobile System is also endowed with an encryption phase through appropriate keys and data compression before transmission. Encryption allows to guarantee the authentication of a patient at the remote end and the certification of the issuer, establishing a secure communication and thus guaranteeing the secrecy and privacy of the communication.
  • the compression of the data allows to optimize the bandwidth of the transmitted signal, using less time for its transmission, with which the communication is faster and more efficient.
  • This phase of encryption and compression of the data to be transmitted can be carried out both by a hardware module, as well as by software as another part of the software implemented in the microprocessor control system.

  • This transtelephonic electrocardiographic monitoring system by means of GPRS presented provides multiple advantages, apart from those mentioned above, over the systems currently available, being the most important, due to the incorporation of the radio communications modem in the Mobile System, this SM You do not need to connect with any computer system or external communications system at any time, since the SM itself forms a single portable device that contains all the necessary elements for its operation at all times.
  • Another subsequent advantage of the present invention is that since the patient does not need any auxiliary peripheral equipment, or computer or external communications system, a telephone line is not necessary, so that the system can be used perfectly for patient monitoring during commuting, both in ambulances and other transport systems.
  • SUBSTITUTE SHEET (RULE 26) Another of the most important advantages of this system is that using the GPRS system for communication allows continuous and periodic monitoring of the electrocardiographic data of the patient, since in the GPRS system the transmission of information is done by packets of data, and the billing of the use of the Internet network is done by the number of packets sent (that is, by the flow of existing information), not by the time of occupation of the network. This allows it to be enough to optimize the latency time between which the data packets are transmitted so that the monitoring of the patient is carried out in a continuous way, without thereby increasing the economic cost of the system, nor for the patient Not for the health system.
  • Another added advantage that occurs when using the GPRS system is the possibility, non-existent in other systems, to perform two-way voice-spoken communication simultaneously and compatible with the transmission of electroencephalographic data. This allows better monitoring by doctors and specialists of the hospital or telecare center of the state of their patients.
