A process and system are provided for controlling a respirator with a breathing circuit (2), an inspiration branch (10) and an expiration branch (12), in which the gas components needed for the respiration are fed in by a fresh gas metering device (20) via a fresh gas line (9), as a result of which

A process and system are provided for controlling a respirator with a breathing circuit (2), an inspiration branch (10) and an expiration branch (12), in which the gas components needed for the respiration are fed in by a fresh gas metering device (20) via a fresh gas line (9), as a result of which at least the amount of breathing gas consumed can be replenished. A breathing gas delivery unit (1) is provided in the inspiration branch (10) and with a volume flow sensor (13) in the expiration branch (12). The fresh gas utilization of the respirator is improved and the process and system reduces the resistances in the breathing circuit (2) for the patient (3) by the breathing gas delivery unit (1) being returned during the phase of expiration at a speed that depends on the volume flow that is measured by the volume flow sensor (13). A maximum percentage of the breathing gas volume expired via the expiration branch (12) reaches the breathing gas delivery unit (1) and can be displaced from there to the patient (3) via the inspiration branch (10).

The inhaling device of claim 7 further comprising means for securing the capsule within the device, said means for securing the capsule comprising said cover having walls, which covers the first chamber, and two outer protrusions on the walls of the cover that stop under a pair of inner protrusions of the first chamber, thereby preventing the cover from accidentally escaping from its place. 10. The inhaling device of claim 9 further comprising means to allow the cover to move perpendicularly with respect to the capsule until the cover abuts the inner protrusions, wherein said spring, inside the first chamber, touches an outer edge of the hollow portion of said second chamber on its lower side and an inner surface of the cover on its upper side. 11. The inhaling device of claim 8 wherein said pointed element within said cover passes through said spring whereby when pressure is applied to the cover, the pointed element will perforate the capsule placed into the hollow portion, thereby releasing the powder medicament into the aperture of said lower chamber and holding pieces of the case in the reservoir. 12. The inhaling device according to claim 7, wherein the capsule is located in the hollow portion of said compartment in a substantially horizontal position when the cover is vertical, or in a substantially vertical position when the cover is horizontal thereby allowing the cutting element to perforate the capsule when the cover is pressed respectively down in a vertical and perpendicular direction towards the capsule, or laterally, in a horizontal and perpendicular direction towards the capsule. 13. The inhaling device according to claim 3, wherein the operation of incision of the capsule and consequent inhalation of the powdered medicament by the user can be performed by holding the inhaling device with one hand, and rotating the cover with the other hand until the cutting element connected to the cover touches a lower part of the capsule and the device is placed in the user's mouth and the powdered drug inhaled. 14. The inhaling device according to claim 4, further comprising an accessory made of rubber or other suitable material that is placed over the mouthpiece of the inhaling device, where it is locked thereto due to a flange thereby allowing the user to inhale the powdered medicament from an opening in the mouthpiece. 15. The inhaling device according to claim 1, wherein said device can be conveniently and easily carried, due to its small size, and can simplify and reduce operations that must be performed for the inhalation of the powdered medicament by the user, the shape and position of the chambers of the device allowing the user to perform the operation of the incision of the capsule and consequent inhalation of the powdered medicament with a single hand, using a single finger to cause the incision of the capsule, while with the rest of the hand of the user can place the device into his or her mouth and the powdered medicament inhaled. 16. The inhaling device according to claim 8, wherein the powdered medicament is released into the device is inhaled by the user by placing the outer end of said lower chamber opposite said reservoir into his or her mouth or nose and breathing in so that the powdered medicament coming out from the mouthpiece enters the mouth or nose and reaches the lungs. 17. The inhaling device according to claim 1, wherein the device is made of plastic material and may be disposed of after each use, so as to guarantee the greatest comfort. 18. The inhaling device according to claim 5, wherein the spring is made of metal, plastic or other suitable material ensuring proper flexibility, such that sufficiently moderate press
