Description

Przedmiotem wynalazku jest elektrorynospiro¬ graf sluzacy do pomiaru i rejestracji przeplywu powietrza w górnych drogach oddechowych.Znany jest przyrzad, w którym do pomiaru prze¬ plywu powietrza w drogach oddechowych uzywa sie czujnika skladajacego sie z metalowej rurki w której umieszczona jest zrolowana siatka me¬ talowa.Znany jest równiez spirometr który posiada po¬ dobna budowe do czujnika wspomnianego wyzej, przy czym oprócz zwezki ma termistor, który prze¬ twarza wielkosci przeplywu na wielkosc elektrycz¬ na. Ponadto znane sa równiez zwezki stosowane do pomiaru przeplywów gazów i cieczy.Niedogodnosc znanych przyrzadów polega na tym, ze prowadzony pomiar obarczony jest ble¬ dem powstalym w wyniku osadzania sie pary wod¬ nej na siatce lub duza bezwladnoscia pomiaru uzalezniona od charakterystyki termistora.Dodatkowa niewlasciwoscia znanych rozwiazan jest to, ze konsrtmtfkicie ich umfemoziliiiwiiaja pomiar fizjologicznego oddechu przez nos.Celem wzoru bylo wyeliminowanie wystepuja¬ cych niedogodnosci w znanych rozwiazaniach. Cel ten zostal osiagniety przez opracowanie urzadze¬ nia w którym sonde pomiarowa umieszcza sie na drodze fizjologicznego przeplywu powietrza odde¬ chowego, która posiada rurke ze zwezka dzielaca przestrzen wewnetrzna rurki na dwie komory któ¬ rych objetosci sa krotnoscia objetosci zwezki i nie 10 \% 25 30 sa sobie równe. Elektrorynospirograf podstawowy zostal na rysunku przedstawiony w formie sche¬ matu blokowego urzadzenia na którym widoczny jest przekrój wzdluzny sondy pomiarowej.Urzadzenie sklada sie z sondy pomiarowej 1 po¬ laczonej przez króciec 6 i 7 drenami 8 z przetwor¬ nikiem pojemnosciowym 9. Sonda pomiarowa 1 u- zbrojona jest w wymienna wkladke nosowa 5.Wewnatrz sondy pomiarowej 1 usytuowana jest zwezka 2ikttóra dzieli przestrzen wewtnejtirmna sondy na dwie komory: wstepna 3 i wylotowa 4. Króciec 6 polaczony jest z komora wstepna 3, zas króciec 7 z komora wylotowa 4.Objetosc komór wstepnej 3 i wylotowej 4 po¬ wstalych wskutek usytuowania zwezki 2 w prze¬ strzeni wewnetrznej sondy jest tak dobrana, ze przy wydechu i wdechu powietrza o tej samej wielkosci powoduje powstanie tej samej róznicy cisnien lecz ze znakiem przeciwnym miedzy króc¬ cami 6 i 7.Róznica cisnien podawana jest drenami 8 z son¬ dy pomiarowej 1 na przetwornik pojemnosciowy 9 w którym wystepuje zmiana róznicy cisnien na wielkosc elektryczna. Przetwornik pojemnosciowy 9 umieszczony jest w sprzezeniu zwrotnym obwodu generatora astabilnego 10 tworzac mostek pomia¬ rowy.Sygnal elektryczny po usrednieniu w ukladzie calkujacym 11 podawany jest na wzmacniacze 113 693113 693 pradu stalego 12 i dalej na miernik analogowy 13 i rejestrator 14.Miernik analogowy 13 posiada zero posrodku skali otrzymujac wychylenie wskazówki w lewo lub prawo od srodka skali w zaleznosci od kie¬ runku przeplywu powietrza przez sonde pomiaro¬ wa 1, co odpowiada wdechowi lub wydechowi po¬ wietrza. Urzadzenie nadaje sie do pomiarów prze¬ plywu powietrza oddechowego stosowanych w oto¬ laryngologii, neurologii i rynologii.Zastrzezenie patentowe Elektrorynospirograf skladajacy sie z rurki ze zwezka, znamienny tym, ze zwezka (2) usytuowa¬ na w sondzie pomiarowej (1) posiadajaca ksztalt rurki, dzieli przestrzen wewnetrzna rurki na dwie komory (3 i 4), których objetosci sa krotnoscia objetosci zwezki (2) i nie sa sobie równe. 10 Drukarnia Narodowa, Zaklad Nr 6, zam. 38/82 Cena 45 zl PLThe subject of the invention is an electrospirograph for measuring and recording the air flow in the upper respiratory tract. There is a known device in which to measure the air flow in the respiratory tract, a sensor consisting of a metal tube in which a rolled metal mesh is placed is used. There is also known a spirometer which has a similar structure to the sensor mentioned above, but in addition to a tube, it has a thermistor which converts the flow rate into an electric quantity. Moreover, there are also known plugs used to measure the flow of gases and liquids. The disadvantage of known instruments is that the measurement carried out is burdened with a bleed resulting from the deposition of water vapor on the grid or a large measurement inertia depending on the characteristics of the thermistor. of known solutions is that their efficiency is measured by the measurement of physiological nasal breathing. The aim of the formula was to eliminate the inconvenience of known solutions. This goal was achieved by developing a device in which the measuring probe is placed by the physiological flow of respiratory air, which has a tube with a taper dividing the inner space of the tube into two chambers, the volumes of which are times the volume of the taper and not 10% 25 30 are equal to each other. The basic electroryinospirograph is shown in the figure in the form of a block diagram of the device, which shows the longitudinal section of the measuring probe. The device consists of a measuring probe 1 connected by a stub pipe 6 and 7 with a capacitive converter 9. - it is armed with a replaceable nose piece 5. Inside the measuring probe 1 there is a stub 2ikt, which divides the inner space of the probe into two chambers: preliminary 3 and outlet 4. Spigot 6 is connected with the inlet chamber 3, and the connector 7 with the outlet chamber 4. The volume of the chambers the initial 3 and outlet 4 resulting from the location of the tube 2 in the inner space of the probe is so selected that when exhaling and inhaling air of the same size, it causes the same pressure difference, but with the opposite sign between the ports 6 and 7. The pressure difference is given by the drains 8 from the measuring probe 1 to the capacitive transducer 9, in which there is a change in the pressure difference to the value c electric. The capacitive converter 9 is placed in the feedback loop of the astable generator 10, creating a measuring bridge. The electric signal, after averaging in the calibrating system 11, is fed to the amplifiers 113 693 113 693 DC 12 and then to the analog meter 13 and the recorder 14. The analog meter 13 has zero in the center of the scale giving the pointer to the left or right of the center of the scale depending on the direction of air flow through the probe 1, which corresponds to the inhalation or exhalation of air. The device is suitable for measuring the flow of respiratory air used in otolaryngology, neurology and rhinology.
