A device for reducing dead space in a ventilator system has a first tube connectable to the dead space in the ventilator system for producing a flow path for the transport of gas from dead space in the ventilator system, a suction device connected to the first tube for generating an adjustable negative pressure in the first tube, a second tube connectable to dead space in the ventilator system, for producing a flow path for the transport of gas to dead space in the ventilator system, a pump connected to the second tube for generating an adjustable positive pressure in the second tube, and a control unit which regulates the suction device and the pump. The suction device and the pump are formed by a first chamber and a second chamber, respectively, in an enclosure, separated by a gas-tight, moving partition. The control unit regulates the moving partition to regulate the suction device and the pump for achieving simpler and more reliable operation. |
