Abstract

"TRANSDUTOR DE PRESSãO PORTáTIL, PNEU-MOTACÈMETRO PARA USO COM O MESMO, E MéTODOS ASSOCIADOS". A presente invenção refere-se a um sistema para detectar a pressão respiratória que inclui um transdutor de pressão portátil configurado para ser conduzido por ou próximo a um conduto respiratório, tal como um circuito de respiração ou uma cânula nasal. O transdutor de pressão portátil pode removivelmente ser acoplado com um pneumotacómetro, na forma de um adaptador de via aérea, disposto ao longo do conduto respiratório. O pneumotacómetro pode incluir duas portas de pressão posicionadas em lados opostos de uma obstrução, que parcialmente bloqueiam o fluxo através de um conduto principal do pneumotacómetro. Condutos de amostra correspondentes do transdutor de pressão portátil são removivelmente acoplados com as portas de pressão. As portas de pressão podem ter elementos de vedação que são configurados para vedarem contra membros de perfuração dos condutos de amostra com a introdução dos membros perfurantes através dos mesmos. Com a remoção dos membros perfurantes, os elementos de vedação são substancialmente resselados. Métodos para usar o sistema são também descritos.
