[002] Currently, the solutions provided on the market present the use of cardiac and multiparametric monitors in the ICU and surgical center and ultrasound or echocardiogram equipment that depend on an operator to perform the exam.
[003] Algumas soluções relacionadas à tecnologia são divulgadas no estado da técnica através do documento número EP2667783, por exemplo, que descreve um sistema, método e dispositivo para determinação automática e autónoma de parâmetros hemodinâmicos e cardíacos usando ultrassom. [003] Some solutions related to the technology are disclosed in the prior art through document number EP2667783, for example, which describes a system, method and device for automatic and autonomous determination of hemodynamic and cardiac parameters using ultrasound.
[004] A presente divulgação se refere a um dispositivo de ultrassom, sistema e um método para determinação de parâmetros cardíaco e/ou hemodinâmicos de forma não invasiva, automática e autónoma e, portanto, não depende de imagens de ultrassom e/ou análise de um cuidador qualificado. O monitoramento cardíaco pode ser fornecido por diferentes técnicas de vários níveis de invasividade, por exemplo, invasivo, minimamente invasivo e não invasivo. Por exemplo, angiografia, angiografia, cateterismo cardíaco, cateterismo cardíaco direito e cateterismo cardíaco esquerdo podem ser considerados invasivos ou minimamente invasivos. Alternativamente, técnicas baseadas em ultrassom, como ecocardiograma, pode ser considerado método não invasivo para determinar os parâmetros cardíacos e/ou hemodinâmicos. O sistema não requer o envolvimento de um profissional de saúde qualificado para determinar parâmetros hemodinâmicos e/ou cardíacos, em vez disso, o dispositivo e método de acordo com uma modalidade preferencial da presente divulgação, fornecem determinação automática e autónoma de cardíaca e/ou parâmetros hemodinâmicos. Tais informações são expostas ao funcionário de saúde o cuidador através de uma memória legível por computador, um monitor de computador, uma impressão, um computador em uma rede ou um usuário, entre outros. [004] The present disclosure refers to an ultrasound device, system and method for determining cardiac and/or hemodynamic parameters in a non-invasive, automatic and autonomous way and, therefore, does not depend on ultrasound images and/or analysis of a qualified caregiver. Cardiac monitoring can be provided by different techniques at various levels of invasiveness, e.g. invasive, minimally invasive and non-invasive. For example, angiography, angiography, cardiac catheterization, right heart catheterization, and left heart catheterization can be considered invasive or minimally invasive. Alternatively, ultrasound-based techniques such as echocardiography can be considered a non-invasive method to determine cardiac and/or hemodynamic parameters. The system does not require the involvement of a qualified healthcare professional to determine hemodynamic and/or cardiac parameters, rather, the device and method according to a preferred embodiment of the present disclosure, provide automatic and autonomous determination of cardiac and/or parameters hemodynamic. Such information is exposed to the health worker or caregiver through a computer-readable memory, a computer monitor, a printout, a computer on a network or a user, among others.
[005] Todavia, tal divulgação determina apenas o fluxo sanguíneo que passa pelos vasos (fluxo arterial), usando metodologia doppler do ultrassom, fazendo uma estimativa do fluxo sanguíneo que passa pelo coração do paciente, de modo que a estimativa se dá por fórmulas matemáticas que fazem um aproximação destes dados. Desta forma, a medição do fluxo sanguíneo que passa pelo coração não é precisa, podendo variar muito conforme cada paciente. [005] However, such disclosure only determines the blood flow that passes through the vessels (arterial flow), using ultrasound doppler methodology, making an estimate of the blood flow that passes through the patient's heart, so that the estimate is given by mathematical formulas that approximate these data. In this way, the measurement of blood flow through the heart is not accurate and can vary greatly according to each patient.
[006] Além disso, a invenção prevê uma 'área de varredura estática', onde a varredura de ultrassom é realizada sobre um local estacionário ou estático, por exemplo, ao longo do torso, tórax, lado posterior do sujeito ou semelhante. Desta forma, é possível perceber que o equipamento necessita de uma pluralidade de transdutores, aplicados ao longo do torso do paciente. [006] Furthermore, the invention provides for a 'static scanning area', where the ultrasound scan is performed over a stationary or static, e.g. along the torso, chest, posterior side of the subject or the like. In this way, it is possible to perceive that the equipment needs a plurality of transducers, applied along the patient's torso.
[007] O documento EP3471624 descreve um sistema e método para determinar os parâmetros hemodinâmicos relacionados ao coração de um paciente. O sistema compreende uma sonda de ecocardiograma transesofágico (TEE) incluindo um transdutor de ultrassom que compreende uma matriz de elementos piezoelétricos e um ou mais processadores operativamente conectados à sonda de ecocardiograma transesofágico (TEE) e/ou outros componentes. A sonda de ecocardiograma transesofágico (TEE) é configurada para obter uma pluralidade de visualizações clinicamente relevantes do coração do paciente em uma única posição. Todavia, o sistema apresenta sistema de leitura de parâmetros invasivo, conforme uso de ecocardiograma transesofágico (TEE). Para isso, necessita de um operador técnico para inserção e acompanhamento do paciente durante o uso do aparelho. Além disso, o equipamento deve ser descartado após utilização. [007] EP3471624 describes a system and method for determining hemodynamic parameters related to a patient's heart. The system comprises a transesophageal echocardiogram (TEE) probe including an ultrasound transducer comprising an array of piezoelectric elements and one or more processors operatively connected to the transesophageal echocardiogram (TEE) probe and/or other components. The transesophageal echocardiogram (TEE) probe is configured to obtain a plurality of clinically relevant views of the patient's heart in a single position. However, the system has an invasive parameter reading system, according to the use of transesophageal echocardiography (TEE). For this, it needs a technical operator to insert and monitor the patient during the use of the device. In addition, the equipment must be discarded after use.
[008] Com base nos problemas existentes no estado da técnica, é revelado um método e equipamento de monitoramento de parâmetros cardíacos baseado em ultrassom para acompanhamento contínuo de pacientes críticos, com sistema de leitura de parâmetros hemodinâmicos e cardíacos não invasivo, que resolve os problemas de realização de avaliações cardiológicas e hemodinâmicas complexas em pacientes críticos de forma contínua, automatizada e simples, para o direcionamento do seu tratamento. [008] Based on the existing problems in the state of the art, a method and equipment for monitoring cardiac parameters based on ultrasound is revealed for continuous monitoring of critical patients, with a non-invasive hemodynamic and cardiac parameter reading system, which solves the problems performing cardiological assessments and complex hemodynamics in critically ill patients in a continuous, automated and simple way, to guide their treatment.
[009] O método e equipamento de monitoramento de parâmetros cardíacos baseado em ultrassom para acompanhamento contínuo de pacientes críticos apresenta um equipamento para medição do fluxo sanguíneo dentro do coração, de forma direta, através de um dispositivo não invasivo que não necessita de acompanhamento contínuo de operador técnico e não necessita ser removido ou trocado ao longo do tempo. [009] The method and equipment for monitoring cardiac parameters based on ultrasound for continuous monitoring of critical patients presents an equipment for measuring blood flow within the heart, directly, through a non-invasive device that does not require continuous monitoring of technical operator and does not need to be removed or replaced over time.
[010] A medição do fluxo é realizada por meio de um transdutor setorial, usado em equipamento de ecocardiografia, que utiliza software e algoritmos para monitorização contínua e não pontual ou momentânea, de parâmetros hemodinâmicos, a beira do leito, utilizando equipamento de ultrassom/ecocardiograma, que uma vez posicionado sobre o tórax do paciente, deve funcionar de forma autónoma, sem auxílio de um operador para a avaliação continuada de seus parâmetros. [010] Flow measurement is performed using a sectoral transducer, used in echocardiography equipment, which uses software and algorithms for continuous and non-punctual or momentary monitoring of hemodynamic parameters, at the bedside, using ultrasound/ echocardiogram, which, once positioned on the patient's chest, must function autonomously, without the assistance of an operator for the continuous evaluation of its parameters.
[011] O equipamento é desenvolvido através de um probe de ecocardiograma instalado em aparelho móvel, conectado via cabo ou Wi-Fi com monitor de tela touch screen, rodando software de monitorização com linguagem de programação Java/DICOM/ imagens em DICOM. [011] The equipment is developed through an echocardiogram probe installed in a mobile device, connected via cable or Wi-Fi with a touch screen monitor, running monitoring software with Java/DICOM programming language/DICOM images.
[012] O presente pedido de patente de invenção, consiste em um método e equipamento de monitoramento de parâmetros cardíacos baseado em ultrassom para acompanhamento contínuo de pacientes críticos, que utiliza software (aplicativo) e algoritmos (inteligência artificial) para monitorização contínua e não pontual ou momentânea, de parâmetros hemodinâmicos, a beira do leito, utilizando equipamento de ultrassom/ecocardiograma, que uma vez posicionado sobre o tórax do paciente, permanece fisicamente estático, e deve funcionar de forma autónoma, sem auxílio de um operador para a avaliação continuada do coração e de seus parâmetros, fluxos sanguíneos e movimentos. [012] The present patent application consists of a method and equipment for monitoring cardiac parameters based on ultrasound for continuous monitoring of critical patients, which uses software (application) and algorithms (artificial intelligence) for continuous and non-punctual or momentary monitoring of hemodynamic parameters, at the bedside, using ultrasound/echocardiogram equipment, which, once positioned on the patient's chest, remains physically static, and must function autonomously, without the aid of an operator for the continuous assessment of the heart and its parameters, blood flows and movements.
[013] O sistema de monitoramento de parâmetros hemodinâmicos consiste na leitura de dados de um paciente através de um transdutor setorial e equipamento de ecocardiografia, feito de forma não invasiva, de modo que o transdutor de ecocardiograma é posicionado sobre o tórax do paciente, fixado com acessório apropriado, preferencialmente próximo ao coração, e o ecocardiograma faz a leitura contínua dos parâmetros de fluxo sanguíneo e movimentos no interior do coração, onde é possível medir de forma exata tais parâmetros, como velocidade de fluxo, volume de fluxo, pressão sanguínea e outros parâmetros. [013] The hemodynamic parameters monitoring system consists of reading a patient's data through a sector transducer and echocardiography equipment, made in a non-invasive way, so that the echocardiogram transducer is positioned on the patient's chest, fixed with an appropriate accessory, preferably close to the heart, and the echocardiogram continuously reads the parameters of blood flow and movements inside the heart, where it is possible to accurately measure such parameters, such as flow velocity, flow volume, blood pressure and other parameters.
[014] O sistema de monitoramento contínuo e automatizado é realizado por um sistema de software e algoritmos específicos, desenvolvidos especificamente para a função aqui estabelecida, o qual faz a avaliação dos parâmetros por meio de fórmulas já existentes na ecocardiografia, como pressão venosa e débito cardíaco, além de outros parâmetros, porém, sem necessitar de operador técnico, ou interpretação complexa de dados do monitor. Tal invenção soluciona o problema de demandar da presença de um médico especialista para realizar um exame de ultrassom/ecocardiograma em períodos que julgar necessário. [014] The continuous and automated monitoring system is performed by a software system and specific algorithms, developed specifically for the function established here, which evaluates parameters through formulas already existing in echocardiography, such as venous pressure and output heart rate, in addition to other parameters, however, without requiring a technical operator or complex interpretation of monitor data. Such an invention solves the problem of demanding the presence of a specialist doctor to perform an ultrasound/echocardiogram exam in periods that he/she deems necessary.
[015] O monitoramento de dados é realizado de forma autónoma pelo sistema de software e algoritmos, sem auxílio de um operador, seja enfermeiro ou médico, para a avaliação contínua do coração e de seus parâmetros. [015] Data monitoring is performed autonomously by the software system and algorithms, without the help of an operator, whether nurse or doctor, for the continuous assessment of the heart and its parameters.
[016] O monitoramento de parâmetros hemodinâmicos é realizado por equipamento de ecocardiograma e transdutor setorial fixo ao tórax, é pré analisado pelo sistema de algoritmos do software de processamento, fazendo com que os dados sejam fornecidos de forma autónoma e automática em um monitor, que apresenta os respectivos dados simplificados, direcionando as condutas ou sugestão de tratamento. [016] The monitoring of hemodynamic parameters is performed by echocardiogram equipment and a sectoral transducer fixed to the chest, it is pre-analyzed by the algorithm system of the processing software, causing the data to be provided autonomously and automatically on a monitor, which presents the respective simplified data, directing the conduct or suggestion of treatment.
[017] O sistema de algoritmos do software recebe os dados da leitura do transdutor setorial fixo ao tórax por meio do equipamento de ecocardiografia, analisa os parâmetros hemodinâmicos complexos e faz o processamento dos dados, apresentando os dados simplificados em um monitor cardíaco, além de prever o direcionamento de condutas e sugestão de tratamento do paciente, ou até mesmo sugerir diagnósticos de um paciente. [017] The software algorithm system receives the reading data from the sector transducer fixed to the chest through the echocardiography equipment, analyzes the complex hemodynamic parameters and processes the data, presenting the simplified data on a cardiac monitor, in addition to predict the direction of conducts and suggestion of treatment of the patient, or even suggest diagnoses of a patient.
[018] Assim, o monitor cardíaco irá sugerir condutas e/ou diagnósticos usando a ecocardiografia para análise automatizada de parâmetros hemodinâmicos, de forma contínua, permanecendo acoplado ao paciente pelo período que o médico julgar necessário - horas ou dias. [019] O transdutor setorial pode ser mantido no paciente durante todo o período de tratamento, não necessitando ser trocado ao longo do tempo, fazendo com que o monitoramento do paciente não seja interrompido, além de não gerar descarte de material caso o paciente precise de acompanhamento por longo período. Além disso, o monitoramento é realizado em tempo real, sendo que, após o desligamento do equipamento ou retirada do transdutor setorial, o monitoramento é interrompido. [018] Thus, the cardiac monitor will suggest conducts and/or diagnoses using echocardiography for automated analysis of hemodynamic parameters, continuously, remaining attached to the patient for the period that the doctor deems necessary - hours or days. [019] The sector transducer can be kept on the patient throughout the treatment period, not needing to be changed over time, so that patient monitoring is not interrupted, in addition to not generating material disposal if the patient needs long-term follow-up. In addition, monitoring is performed in real time, and after the equipment is turned off or the sector transducer is removed, monitoring is interrupted.
[020] Um paciente que necessita de avaliação de seu estado hemodinâmico, normalmente em situação grave, será acoplado a equipamento de ultrassom/ecocardiograma, que permanecerá em sua posição de forma contínua, sendo monitorado seus parâmetros hemodinâmicos complexos e processados os respectivos dados, por meio de algoritmo, para transmissão em telas de um monitor cardíaco, que apresenta parâmetros simplificados e direcionamento de condutas ou sugestão de tratamento, ou até mesmo sugerir diagnósticos de um paciente. É possível acessar os parâmetros de forma mais completa em sub-telas/janelas acessórias. Com cores diferentes para cada parâmetro e sugestão de conduta. [020] A patient who needs an assessment of their hemodynamic status, usually in a serious situation, will be coupled to an ultrasound/echocardiogram equipment, which will remain in their position continuously, their complex hemodynamic parameters being monitored and the respective data processed, for algorithm, for transmission on screens of a cardiac monitor, which presents simplified parameters and direction of conducts or treatment suggestion, or even suggest diagnoses of a patient. It is possible to access the parameters more completely in sub-screens/accessory windows. With different colors for each parameter and suggestion of conduct.
[021] Tal equipamento poderá ser utilizado em pessoa em sua residência, de forma a monitorar os mesmos parâmetros à distância, de forma contínua, porém com intuito diagnóstico. Eventualmente, com o avanço da tecnologia, associado a outros dispositivos, poderá realizar tratamentos ou assistência automatizada. Assim, ele poderá ser utilizado tanto em ambiente hospitalar, quanto ambulatorial, com finalidades diferentes. [021] Such equipment can be used in person at your home, in order to monitor the same parameters remotely, continuously, but with a diagnostic purpose. Eventually, with the advancement of technology, associated with other devices, you will be able to perform treatments or assistance automated. Thus, it can be used both in hospital and outpatient settings, with different purposes.
