Description

"BIOMEDICAL PATIENT SIGNALS REMOTE MONITORING DEVICE"

This patent application addresses a "BIOMEDICAL PATIENT SIGNAL REMOTE MONITORING DEVICE", especially a device incorporating monitoring means such as oximetry, blood pressure meter, body temperature meter and electrocardiogram with signal treatment. and digital transmission via a signal transmission interface to a medical facility.

In a preferred embodiment, the device claimed here reads the cited biomedical data and feeds a real-time control panel in which patient-specific parameters are enabled whereas identified changes act as a device to trigger medical help through the devices. known media, such as e-mail, landline, cell phone among others already known and used by society.

Nevertheless, the present invention is directed to individuals who need comprehensive care because they have cardiopulmonary disease or elderly patients with imminent risk of death protected at home or in public facilities.

In contemporary times the technological advancement in the medical field reveals several equipments that seek to monitor the life of patients registering biomedical data for later analysis and treatment. In emergency occurrences, patients with critical pathologies need monitoring through a companion who activates the emergency services. It is well known that the faster the care, the greater the chances of patient survival. As these services are not always correctly offered to the population, the applicant envisioned the possibility of materializing a remote device implanted in the patient's body to capture and send biomedical signals.

In the state of the art there are some solutions such as PI PI0803961-5 of 19/03/2008 which deals with a system and its apparatus for testing, measuring and controlling vital signs in the living organism through real time monitoring and computer visualization, more precisely, the telemetry system employs a conventional apparatus of the type provided with specific sensors such as, for example, electromagnetic chest straps, infrared oximeters or electrical signals, electrodes, among others that remain coupled to the monitored individual; This system receives and manages the data - vital signals - sent by the device, allowing this captured data to be compared with the data already registered in the monitored medical record and to be displayed on suitable equipment, such as a notebook, palmtop or other used by users. registered; The data captured in the monitored, as well as all other registration data, medical records and registration are stored on the web, in virtual directories, in order to make possible the visual monitoring of the monitored individual or user, such as doctors, physical trainers, nurses. , among others; The structure of the telemetry system is composed of the local module and the web module.

This solution provides for conventional

read biomedical data and claim its transmission to a central and describe a software with its respective screens and registration functionalities. However, it is true that this document has a descriptive insufficiency, as it does not technically disclose the relevant technical characteristics for a person skilled in the art to materialize the alleged invention. Further, the presented solution only describes a generic invention. Another solution disclosed in the prior art is PI 9404190-3 of 10/17/94 which deals with an apparatus to be connected to computers for the acquisition of biomedical signal data, especially electrocardiography / encephalogy signals, with software that allows that data is stored, viewed, printed, or transmitted remotely via telephone line or other means of telecommunication. The application of this device consists of besides storing, displaying and printing data of biomedical signals, transmitting them remotely for verification. The field of use extends between ordinary people, governments, and businesses that need remote verification (or diagnosis), doctors who want to exchange patient data with each other. Already this solution needs a computer to collect the data and still uses an outdated technology that has restrictive aspects of reading and data transmission in addition to requiring an individual to identify possible occurrences.

The present invention discloses in detail its technical features with innovative operational features that solve the problems revealed in the state of the art and for that the inventive activity is characterized by the electronic means that allow a new device "BIOMEDICAL PATIENT SIGNAL REMOTE MONITORING DEVICE".

Figure 1 reveals the detailed block diagram.

of the present invention;

According to Figure 1 the "BIOMEDICAL PATIENT SIGNAL REMOTE MONITORING DEVICE" to monitor biomedical patient signals using an ECG, oximeter, pressure and temperature equipment connected via USB interfaces to a USB / analog converter characterized by the fact USB / Analog converter, switches with a microcontroller-controlled multiplex module where samples of the biomedical signals provided by the analog amplifier converter are connected to the digital Analog converter at interfaces Ain 1 to Ain 3, inputs Ain 1 and Ain 2 of the 12-lead ECG signals are processed, for this the micro controller will select two by two signals received in the converter and stored in memory in packets of appropriate size; and by said signals packaged in packets of specific size by the microcontroller and stored in the same memory for later transmission through a TX XBEE module - pro simultaneously with the ECG signal.

Duly identified signals are transmitted to

a server via the internet. The output signal identified as SDATA of the Xbee module will be transmitted after being stored in memory for the period necessary for the biomedical signal to be stored in a standardized and secure manner by the sensor module to be connected to the input of the apparatus prior to the filter and input multiplexer module. In a preferred embodiment the XBee module includes antenna on the remote equipment and a standard WIF12.4Ghz receiver, on the receiver the XBEE_PRO / USB module performs the connection of the remote module with a PC to store the biomedical signals and send to the WEB server via In this way, the memory of the microcontroller only stores the data selected by the multiplex for sending to the server PC at the patient's house and only during the required acquisition time.

At each monitoring period will be transmitted to the WEB server the Biomedical signals packed in packages with patient identification and equipment, for later access by the doctor.
