Respirator intended for pulmonary patients and for indisposed or unconscious persons. The respirator comprises a drug atomizer (13), a supply pressure source communicating with the drug atomizer (13) for conducting air or oxygen, an injector (21) communicating with the drug atomizer (13), and control valves (15, 16) for regulating the atomizing rate of the drug atomizer (13), respectively the respiration pressure. The respirator is composed of a modular system comprising a basic unit consisting of a drug atomizer (13) and a control valve (15) thereto connected, by the aid of which the air or oxygen flow to the drug atomizer (13) can be regulated, and a first tube-like connector (18) which by one end can be connected to the inlet connector (19) of the control valve (15) and by its other end to a connector (20)) communicating with the supply pressure source. To the modular system has been connected an injector (21) connected to the drug atomizer (13), a second tube-like connector (22) connected by one end to the respiration pressure control valve (16) and by its other end to the injector (21), and an exhalation valve mounted between the mouthpiece (11) and the drug atomizer (13) and by the aid of which the counterpressure to exhalation flow can be steplessly regulated. The respiration pressure control valve (16) has been placed in a branch line (35) between the tube-like connectors (18, 22). The first tube-like connector (18) communicates with the supply pressure line (26) through an electrically controlled magnetic valve (36). The respiration pressure control valve (16) likewise communicates with the supply pressure line (26) through the electrically controlled magnetic valve (36). The control means (37) for the magnetic valve (36) comprises a first timing means for setting the operating period of the respirator to conform to the patient's respiratory rhythm, respectively a second timing means for regulating the rest period of the respirator to conform to the patient's respiratory rhythm. |
