Abstract
The invention is related to devices for inhalation therapy that allow optimizing the delivery of the medicament either directly to the mouth, the tracheostomy of the patient, or through the use of an oronasal mask. The inhalation flow chamber (1) comprises a mixed connector (3), an anterior body (19) with an exhalation window (15) housing an exhalation unidirectional membrane (5), an inhalation unidirectional membrane (10), a valve seal (14), a cylinder (18), a coupling port for the pressure indicator (20), a flow indicator (17), a lid for the chamber (7) and a coupling port for the metered-dose inhaler (6).
Claims4
An inhalation flow chamber (1) comprising:
- a mixed connector (3), an anterior body (19) with an exhalation window (15) housing an exhalation unidirectional membrane (5), arranged towards the proximal section of the inhalation chamber;
- an inhalation unidirectional membrane (10), a valve seal (14), a cylinder (18), a coupling port for the pressure indicator (20) and a flow indicator (17), arranged in the middle section of the inhalation chamber;
- a chamber lid (7) and a coupling port for the metered dose inhaler (6), arranged in the distal section of the inhalation chamber;
- wherein the mixed connector (3) is coupled to the anterior body (19), which is coupled to the proximal end of the cylinder (18), within which the unidirectional inhalation membrane (10) and the valve seal (14), which supports said membrane are arranged;
- wherein the cylinder (18) is in connection with the chamber lid (7) at its distal end;
- wherein the flow indicator (17) is in connection with the cylinder (18), through the connection of a flow passage conduit (13) with the coupling port (20);
- wherein the flow indicator (17) comprises a flow level of 30 L/min (11) and a flow level of 60 L/min (12);
- wherein the cylinder (18) comprises two dismantlable sections (18A, 18b);
- and
- wherein the flow indicator (17) is in connection with the second cylinder section (18b), through the connection of the flow passage conduit (13) with the coupling port (20).
