Summary for Patent: 4,224,939
Title: Bacteria-tight system for artificial respiration
Abstract:An appliance for establishing a bacteriologically safe connection between a respirator and an endotracheal tube comprises a head fitting, which is adapted to be mounted on the endotracheal tube. A flexible tube for supplying inhalable gas and a flexible withdrawing tube for withdrawing exhaled air are connected to said head fitting. An exhalation valve is incorporated in the withdrawing tube and is incorporated by a controller in step with the artificial respiration. An inflatable bag, which is manually operable to effect artificial respiration, is connected by a tee fitting to the supply tube, which is connected by a bacteria filter and the controller to the respirator. The inflatable bag is provided with a sensor, which is connected by a signal line to the controller and causes the latter to close and open the exhalation valve in step with the manually effected artificial respiration.
