Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may include one or more flow restrictors to allow controlled release of oxygen enriched gas between the canisters.

The outer film is expandable to a diameter larger than the diameter of a trachea, and in particular is at least 1.5 times the outside diameter of the tube, and the inner film comprises a material of lower elastic stretching. The inner film is produced oversized and without an external restriction at an internal pressure of at most 20 hPa assumes a diameter which is larger than the diameter of a trachea.

Abstract: A convertible reusable diaper is provided, comprised of an outer cover portion, a liner portion, and a detachable absorption portion. The outer cover portion may generally include barrier panels attached at both the front and rear regions of the outer cover portion to form interior pockets. A plurality of fastenable tabs attached to hole-openings at the barrier panels affixes the liner portion or the detachable absorption portion in place. The hole-openings allow the passage of the fastenable tabs through the barrier panels. Both the liner portion and the detachable absorption portion include fastener members inter-engaged with the corresponding fastener members located at the fastenable tabs to allow the liner portion or the detachable absorption portion to be removably affixed to the outer cover portion. Numerous options for affixing the insert portion and the detachable absorption portion allow conversion to different diaper designs.

Abstract: A process for operating a respirator and/or anesthesia device in the APRV mode with the % PEF criterion which includes a detection of a spontaneous expiratory effort by the patient and initiation of a pressure release phase when the detected spontaneous expiratory effort by the patient falls within a predetermined trigger window (Tfreg). A device is provided that is operated correspondingly.

Abstract: Provided is a sanitary napkin having wings that can be easily attached by being properly folded back at correct positions without causing problems in the wing-like flaps, such as adhesion of adhesive surfaces to each other and wrong adhesion. In a sanitary napkin including wing-like flaps disposed on both sides of a main body to be fixed to an undergarment so as to wrap around a crotch portion of the undergarment when it is worn, each wing-like flap has a front outline extending outward from the main body and a back outline extending outward from the main body and is designed such that the angle ? formed by the width-direction line of the sanitary napkin and the back outline is larger than the angle ? formed by the width-direction line of the sanitary napkin and the front outline and that the gravity center of the wing-like flap is located more toward the front of the sanitary napkin than the center point of the boundary line of the root of the wing-like flap W and the main body.

Abstract: An absorbent article includes a chassis extending about a longitudinal axis and having a topsheet, a backsheet and an absorbent structure disposed between the topsheet and the backsheet. The chassis has a first transverse axis dividing the absorbent structure into a front body panel terminating in a front waist region and a rear body panel terminating in a rear waist region. The rear waist region has a first elastic region. The chassis is delimited by opposed longitudinal edges and opposed transverse edges. In the rear waist region, the absorbent structure terminates at a first distance from the transverse edge and the first elastic region extends substantially parallel to the transverse edge and spaced therefrom by a second distance and spaced from the absorbent structure by a third distance. The third distance is greater than said second distance or substantially equal thereto.
