초록 ▼

There is disclosed an anesthesia breathing system which is interconnected between a source of gas, such as an oxygen or an anesthesia administration system, or both, and a patient supported inhalation-exhalation means such as a face mask or the like, which includes concentrically oriented double tubular inhalation and exhalation lines having one of the tubes positioned interiorly of the other tube, spacer means for supporting and maintaining the concentrically oriented tubes and spaced in relatively fixed spacial relation, first uni-directional valve means carried adjacent one end of the tube system and positioned adjacent to the patient supported inhalation-exhalation means to control gas flow through the inhalation tube and second unidirectional valve means adjacent to the first unidirectional valve means to control gas flow through the exhalation tube, such that the double tubular inhalation-exhalation line functions as a heat exchanger to warm the gases as they travel to the patient while at the same time permitting gas flow in the respective lines in one direction only.

대표청구항 ▼

An anesthesia breathing system utilized in connection with systems for the administration of inhalation anesthetic agents, including a source of gas For inhalation positioned at one end of the system and patient-supported inhalation-exhalation means at the opposed end of the system, the improvement comprising in combination, a concentrically oriented double tubular inhalation-exhalation tube extending from one end of said system to the opposed end of said system and having one of said tubes positioned interiorly of the other of said tubes, one of said tubes carrying inhaled gas and the other of said tubes carrying exhaled gas, spacer means for supporting and maintaining said concentrically oriented tubes and spaced in relatively spacial relation, first unidirectional valve means mounted within said inhalation gas tube extending across the diametric dimension of said one of said tubes providing flow only in the direction from said one end of said system to said opposed end of said system and positioned adjacent the patient-supported inhalation-exhalation means for providing unidirectional gas flow therethrough, and second unidirectional valve means mounted within said exhalation gas tube and extending across the diametric dimension of the annular fluidic path between said concentric tubes for providing flow only in the direction from said opposed end of said system to said one end of said system and positioned adjacent the patient-supported inhalation-exhalation means for providing unidirectional gas flow therethrough, said first and second unidirectional valve means each comprising a valve seat and a flexible membrane seatable against said valve seat, said membrane allowing fluid to flow by flexure and movement of the membrane in one direction of applied fluidized pressure, and seatable against said valve seat thus not allowing flow when fluidized pressure is applied in the opposed direction, at least said inhalation line being formed of a flexible material rapidly permeable to heat transfer and the gas flow in said exhalation gas tube being countercurrent with respect to the gas flow in said inhalation gas tube, thereby to stabilize and maintain the temperature of the gas within said gas inhalation tube, without any extraneous source of heat, whereby gas suitable for patient inhalation enters said system through said inhalation tube and through said first unidirectional valve means to the patient while exhaled gas flows through said second unidirectional valve means in countercurrent relation with respect to the gas along said gas inhalation tube for exhaustion and/or purification from said system.
