Abstract

Aparatul pentru respiratie artificiala, conform inventiei, este prevazut cu o comanda electronica si un calculator numeric al frecventei respiratiei, comanda electronica fiind constituita din registre de deplasare, subansamble periferice pentru comanda variatiei volumului, respectiv presiuniii în timpul procesului de respiratie artificiala si module de comanda pentru formarea valorilor limita ale unor combinatii de parametri, registrele de deplasare fiind astfel amplasate încît sa poata fi realizate rapoartele dorite între diferitele etape ale perioadei respiratiei artificiale iar prin conectarea cu supape de curent si de cale sa poata fi realizate diferite tipuri de respiratie artificiala, comanda cu program de temporizare fiind constituita din patru registre de deplasare de patru biti în serie conectate la cîte un întrerupator cu 16 pozitii ce sunt legate pe de o parte cu trei circuite basculante bistabile si cu trei supape magnetice prin intermediul a doua registre identice de deplasare de trei biti, fiind legate între ele pe de-o parte direct si pe de alta parte prin intermediul unui întrerupator cu opt pozitii, iar registrele de deplasare de patru biti fiind legate cu un generator de semnale dreptunghiulare; prin intermediul unui întrerupator cu doua pozitii doua dintre aceste registre fiind legate si la un demultiplicator de frecventa si/sau la un întrerupator cu trei pozitii.According to the invention, the artificial breathing apparatus is provided with an electronic control and a digital breathing frequency calculator, the electronic control being constituted by movement registers, peripheral subassemblies for controlling the variation of volume and pressure during the artificial respiration process and control modules for the formation of the limit values of some combinations of parameters, the displacement registers being positioned so that the desired reports can be made between the different stages of the artificial respiration period and by connecting with current and path valves different types of artificial respiration can be made, the timer program consists of four four-bit shift registers connected in series to a switch with 16 positions which are connected on one side with three bistable and three magnet valves via two identical registers three-bit displacement being connected to one another directly and on the other by means of an eight-position switch, and the four-bit shift registers being connected to a rectangular signal generator; by means of a two-position switch, two of these registers are also connected to a frequency demultiplier and / or to a three-position switch.
