Abstract
Intubacyjny czujnik cisnienia zawiera elastyczna zewnetrzna membrane separujaca (2) umocowana w korpusie (4) tego czujnika i zamykajaca komore pneumatyczna korpusu czujnika, w którym znajduje sie dysza pneumatyczna (1) majaca kanal wylotowy umieszczony centralnie w malej, korzystnie bliskiej zeru odleglosci od wewnetrznej powierzchni membrany separujacej (2) W korpusie czujnika znajduje sie drugi kanal pneumatyczny (6), którego wlot do komory czujnika jest polozony na jej skraju, i który laczy sie za posrednictwem pneumatycznego, rezystora (7) cisnienia ze zródlem nadcisnienia (Pzo). Zródlo podcisnienia (Pe) laczy sie kanalem pneumatycznym (8) o korzystnie mozliwie malej rezystancji z kanalem dyszy pneumatycznej (1) czujnika. Ponadto korpus czujnika (4) ma dodatkowy otwór (5), w którym umocowana jest rurka kapilarna (9) laczaca komore podmembranowa czujnika z pierwszym (11) wejsciem elektropneumatycznego przetwornika (10) róznicy cisnien ?p o drugim wejsciu (12) laczacym sie z atmosfera (Pa). Zródlo nadcisnienia (Pzo) laczy sie dodatkowo z kanalem zasilajacym (17) ezektora pneumatycznego (15), którego wyjsciowy kanal podcisnieniowy (16) stanowi zródlo podcisnienia polaczonego z kanalem dyszy pneumatycznej (1) korpusu czujnika (4).The intubation pressure sensor contains a flexible external separating membrane (2) mounted in the body (4) of this sensor and closing the pneumatic chamber of the sensor body in which the pneumatic nozzle (1) has an outlet channel centrally located in a small, preferably close to zero distance from the inner surface separating membrane (2) The sensor body has a second pneumatic channel (6), whose inlet to the sensor chamber is located on its edge, and which is connected via a pneumatic pressure resistor (7) with an overpressure source (Pzo). The vacuum source (Pe) is connected by a pneumatic channel (8) with preferably a smaller resistance to the pneumatic nozzle channel (1) of the sensor. In addition, the sensor body (4) has an additional hole (5) in which the capillary tube (9) is attached connecting the sensor sub-membrane chamber with the first (11) input of the electropneumatic transducer (10) of the differential pressure after the second input (12) connecting to the atmosphere (Pa). The overpressure source (Pzo) additionally connects to the supply channel (17) of the pneumatic ejector (15), whose output vacuum channel (16) is the source of the vacuum connected to the pneumatic nozzle channel (1) of the sensor body (4).
