SISTEMA WBA: nova facilidade para medir os biosinais

Nova maneira para medir EMG, EEG e ECG
A Mega Electronics Ltd apresenta o novo sistema Wireless BioAmplifier [BioAmplificador Remoto] (WBA) para medição de biosinais como EMG, ECG, EEG de superfície. O sistema de até 32 canais oferece configurações completas de medição com ajuste flexível.

FACILIDADE REMOTA:

Duas versões de sensores WBA estão disponíveis. Uma com eletrodos para medição fixos, uma com fios condutores com conectores de encaixe. Estão disponíveis, também, outros sensores como acelerômetros, goniômetros, como unidade WBA. O sistema WBA é ideal para medir sinais fisiológicos em ambiente hospitalar, laboratórios de análise de movimento e em condições de campo. Os sinais podem ser recebidos utilizando-se um receptor de 8-32 canais ou um simples telefone móvel por Bluetooth.

Conexões com sistemas externos

A unidade receptora do sistema WBA está equipado com saídas USB analógicas e digitais. O receptor também pode enviar dados para outro dispositivo equipado com Bluetooth (PC, telefone móvel ou PDA).

Conexões com sistemas de análise móveis como Vicon, MAC, Qualisys, Simi, CodaMotion, NDI, etc podem ser feitas facilmente utilizando a conexão com saída analógica da unidade receptora do sistema WBA.

UM SISTEMA, MUITAS APLICAÇÕES

O sistema WBA é ideal para muitas aplicações diferentes. Os sensores pequenos e leves são fáceis de serem colocados e as preparações para medição são rápidas. O sistema WBA sempre é entregue com o software MegaWin para PC; portanto, a visualização e a análise do sinal de medição estão disponíveis com apenas uma ferramenta

- Procedimentos de monitoramento de reabilitação
- Monitoramento neurofisiológico
- Pesquisa biomecânica
- Análise do movimento
- Análise de marcha e postura
- Análise de trabalho e ergonomia
- Pesquisa esportiva


Ferramentas completas para visualização e análise de sinais

Totalmente compatível com MegaWin SW

O software MegaWin para PC oferece uma plataforma de aquisição de dados versátil, fácil de usar com uma ampla variedade de características de monitoramento e análise:

 Controle de dados e base de dados pessoais
 Sistema de configuração gráfica e fácil de usar ajustado para diferentes sinais
 Assistente do protocolo para múltiplas aplicações
 Ferramenta de processamento e análise de dados
 Múltiplas características online/em tempo real para espectros brutos, calculados, biofeedback, sons, FFT, etc.
 Mapas musculares/nervoso do corpo inteiro em 3D (opcional)
 Relatórios

O MegaWin inclui ferramentas de controle para ajustes do sistema WBA e controle de medição fácil de usar baseado no protocolo. Os protocolos podem ser criados fácil e rapidamente com o assistente progressivo passo-a-passo. O software inclui mapas anatômicos do sistema muscular com exemplos de colocação dos eletrodos em cada músculo específico.

O arquivo de dados do MegaWin pode ser exportado como arquivo binário, arquivo ASCII e no formato Mathlab para análise adicional. O formato C3D permite inserir dados do MegaWin em sistemas de análise móveis bem equipados. O MegaWin também permite exportação para EDF.
