There is also described a regulator implementing the above method.

Abstract: An exhalation valve 14 for a filtering face mask 10 has a flexible flap 24 that makes contact with a curved seal ridge 30 of a valve seat 26 when the valve 14 is in the closed position. The curvature of the seal ridge 30 corresponds to a deformation curve exhibited by the flexible flap 24 when secured as a cantilever at one end and exposed at its free portion to a uniform force and/or a force of at least the weight of the free portion of the flexible flap. A seal ridge curvature corresponding to a flexible flap exposed to uniform force allows the flexible flap 24 to exert a generally uniform pressure on the seal ridge to provide a good seal. A ridge curvature corresponding to a flexible flap exposed to a force of at least the weight of the flap's free portion allows the flexible flap 24 to be held in an abutting relationship to the seal ridge 30 under any static orientation by a minimum amount of force, thereby providing a face mask 10 with an extraordinary low pressure drop during an exhalation.

Abstract: BACKGROUND: Tracheotomy has been used to assist patients who require mechanical ventilation. Tracheostomy is a common surgical procedure for intensive care patients. The goals of tracheotomy are to bypass the upper airway, facilitate removal of tracheobronchial secretions, prevent aspiration of gastric contents, and to control the airway for prolonged mechanical ventilation. METHOD: The hypothesis was to improve the design of the current tracheostomy tube in order to make it easier to use and to eliminate nearly all of the disadvantages found in prior tracheostomy tubes. RESULTS: This device is an improved tracheostomy tube designed with the balloon cuff (18), guide balloon (26), balloon connector (32) and guide balloon valve (24) located on the inner cannula (12). The inner cannula (12) will be inserted into another tube called the outer cannula (14), which has been inserted into an incision or stoma into the patient's trachea between the vocal cords and carina.

Abstract: Method of urinary continence training, utilizing an objective measurement, indicative of the state of fullness of the bladder of the subject, to identify the occurrence of an appropriate continence training opportunity. When the objective measurement equals or exceeds a signal threshold value, set to correspond to a bladder volume that is less than a reflexive urination volume, a signal is provided to the subject or to a caregiver. The objective measurement may be performed by a bladder monitor, using any of several modalities of automatic sensing, and preferably using ultrasound. The signal threshold value may be recalculated and increased, so as to continue to correspond to a relatively full bladder, as the subject grows and/or achieves progress toward continence. The method may include other steps directed to help the subject associate the physical sensation of a full bladder with voluntary urination, such as informing the subject that urination is imminent.
