<p>The invention relates to a breathing apparatus for controlled inhalation and exhalation for the purpose of therapy of the airways. The patient inhales clean air through an inlet piece (1); exhaled air passes through an outlet piece (2) into the environment. The inlet piece (1) and outlet piece (2) open at an acute angle into a connection piece (3), into whose end a mouthpiece (13) is inserted. Provided in the outlet piece (2) is an exhalation resistance (4), against which the patient exhales. In the inlet piece (1) there is an inlet valve (5), and in the outlet piece (2) there is an outlet valve (6). These valves are both designed as dismountable one-way valves. The outlet valve (6) prevents air being inhaled through the exhalation resistance (4) counter to the intended direction of flow. The patient is supplied with respiratory air exclusively via the inlet piece (1), to which, for example, an aerosol atomising device (15) can be connected. The exhalation resistance (4), inlet valve (5), outlet valve (6) and mouthpiece (13) can be easily removed, so that cleaning and disinfecting of the breathing apparatus can be carried out without any problem. As a result of the inclined entry of the inlet piece (1) and the outlet piece (2) into the connection piece (3), optimal flow conditions are obtained inside the breathing apparatus, for which reason it is less prone to becoming soiled. <IMAGE></p> |
