Abstract
UN DISPOSITIVO INDICADOR DE PRESION (14) PARA DISPOSITIVOS TECNICOS MEDICOS COMO POR EJEMPLO UNA BOTELLA ASPIRADORA DE VACIO (10) MUESTRA UN TUBITO DE MEDICION (22) LLENO CON UN LIQUIDO (30, 32) ASI COMO UN EXTREMO CERRADO Y UNO ABIERTO CONECTADO CON EL INTERIOR DE LA BOTELLA ASPIRADORA DE VACIO (10). ENTRE LOS EXTREMOS CERRADOS DEL TUBITO DE MEDICION (22) Y DEL LIQUIDO (30, 32) EXISTE UNA CANTIDAD DETERMINADA DE UN GAS (34). ESTE DISPOSITIVO INDICADOR DE PRESION SE CARACTERIZA PORQUE EN LA ZONA DEL CANAL TUBULAR DE ESTE TUBITO DE MEDIDICON EXISTE UNA POSICION DE ESTRANGULAMIENTO (28) DE TAL MODO QUE EL LIQUIDO (30, 32) SOLAMENTE PUEDE DESLIZARSE MUY LENTAMENTE A PARESION VARIABLE EN EL INTERIOR DE LA BOTELLA ASPIRADORA DE VACIO EN EL INTERIOR DEL TUBITO DE MEDICION. SE DESCRIBE UN PROCEDIMIENTO PARA FABRICACION DEL TUBITO DE MEDICION.
