초록 ▼

One end of an endotracheal tube is encircled by an inflatable cuff, to which is connected a tubule that extends toward the opposite end of the tube and into a valve housing having an air inlet bore from which passages extend to the tubule and to an inflatable member. The bore contains valve means normally closing off the inlet of the bore, and means for opening the valve to admit air under pressure or to release it therefrom to inflate and deflate the cuff and inflatable member. A constant pressure means is disposed in the housing for exerting a substantially constant bias against the inflatable member throughout a predetermined range of expansion of the inflatable member to maintain preset air inflation pressures within the inflatable member and the cuff substantially constant, even though their respective inflation volumes may vary. An additional feature resides in the fact that the inflatable member is enclosed in the housing and the housing is sealed for expansion and contraction of the inflatable member within the sealed housing, and another tubule communicates the interior of this sealed housing with the interior of the endotracheal tube thereby preventing collapse of the inflated cuff when gas pressures within the endotracheal tube exceed the cuff inflation pressure.

대표청구항 ▼

In combination, an endotracheal tube having distal and proximal ends, a normally collapsed flexible tubular cuff encircling the tube near its distal end and having opposite ends sealed thereto, a tubule extending from the cuff outwardly along said tube and having a distal end communicating with the inside of the cuff, the proximal end of the tubule having an inlet for air under pressure for inflating the cuff, an inflatable member, the tubule inlet fluidically communicating with the interior of the inflatable member, a valve housing provided with an air inlet bore fluidically communicating with the tubule inlet and interior of the inflatable member, valve means in the bore normally closing the inlet thereof, means for opening the valve means to admit air under pressure through said inlet bore to inflate the cuff and the inflatable member, the improvement comprising, said inflatable member mounted within said valve housing for expansion and contraction therein and including constant pressure means disposed in said valve housing between said inflatable member and said valve housing for exerting a substantially constant bias against said inflatable member throughout a predetermined range of expansion of said inflatable member in said valve housing whereby air inflation pressures within said inflatable member and said cuff are maintained substantially constant even though their respective inflation volumes may vary.
