Abstract: A nasal cushion (30) comprises a substantially triangularly shaped frame (32) from which extends a membrane (34). The frame (32) has a scalloped edge (36) by which the cushion (30) is affixed to a mask body. The membrane (34) has an aperture (38) into which the wearer's nose is received. The membrane (34) is spaced away from the rim (40) of the frame (32), and its outer surface (41) is of substantially the same shape as the rim (40). Respective notches (42,44) receive the bridge of the wearer's nose. The wearer's nose is received through the aperture (38) into the chamber within the mask body (46). The seal forming portion (45) thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the base of the nose and the upper lip, and around the sides and over the bridge of the nose. The shape of the seal forming portion (45) is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.

Abstract: A face mask is disclosed that includes a mask portion, a resilient member (e.g., a pillowed web), and, optionally, an adhesive portion. The resilient member and the adhesive portion are alternately positionable between the mask portion and the wearer to inhibit the passage of vapor between the mask and the wearer, which prevents fogging of the wearer's eyewear. A method for using the face mask is also disclosed.

Abstract: A manually manipulated resuscitation mask, which includes a flexible barrier for providing a sealing contact with a face of a victim in a region adjacent to a victim's mouth. The flexible barrier has an opening therethrough to cooperate with the victim's mouth. The opening in the sheet is comprised of an integrally connected, flexible sleeve, extending away from the flexible sheet and the victim's face. The sleeve has an open end remote from where the sleeve is integrally connected to the flexible barrier sheet. The mask also includes a tubular member that has first and second end portions. The tubular member is positionable within the flexible sleeve and has the first end portion integrally secured to the open end of the flexible sleeve. The second end portion of the tubular member is located adjacent to the flexible barrier sheet when the tubular member is positioned within the sleeve. The sleeve and tubular member allow a mouth of a rescuer, when engaging the flexible sleeve and tubular member, to deliver air from the lungs and mouth of a rescuer to and through the tube to the mouth of the victim. A one-way-valve and a filter or combination thereof are fitted into the tubular member. The tubular member is manually moveable such that the second end portion of the tubular member may extend through the flexible sheet to engage a mouth of a victim.

Abstract: A bi/multi-directional air flow filter cartridge includes a filter pad and a filter pad base. The filter pad includes: outer filter walls made of a filter material suitable for filtering at least particulates, the walls being spaced apart to define an inner area therebetween, and to allow air to pass into the inner area from two or more directions; and a gas/vapor adsorber/absorber member, located within the inner area defined by the outer filter walls, the filter walls maintaining a spacing between inner surfaces of the walls and the gas/vapor adsorber/absorber member, wherein the gas/vapor adsorber/absorber member includes an adsorber/absorber upstream portion of its outer surface structured to, in response to a source of suction, receive air that has already been filtered by the filter walls, such that the air passes through at least a minimum length of the gas/vapor adsorber/absorber member and then out of an opening in the filter pad at a downstream portion of the gas/vapor adsorber/absorber member. The filter pad base is attached to the filter pad and includes a connection member located in association with the filter pad opening. The base removably connects the filter unit to a source of suction.

Abstract: Method and device for handling a carbon dioxideabsorbing compound in anaesthetic systems of the circle system type. The anaesthetic system is arranged with an openable container (10) arranged for gas passage in such a way that air mixed with carbon dioxide from the patient who is to be connected to the system, passes through the container in order to be returned to the patient. According to the invention, a quantity of carbon dioxide-absorbing compound (16) is provided with a gas permeable cover (17). The unit, intended for carbon dioxide absorption, designed in this way is placed inside the container (10). When it is considered to be consumed, it is removed from the container and replaced with a new one.

Abstract: A respirator 10 includes a compressible filter element 12, a filter element retainer 14, and a face piece 16. The respirator is unique in that the filter element 12 compresses when installed in the retainer 14, allowing a friction fit to be maintained between the filter element 12 and retainer 14. The friction fit enables the filter element 12 to be readily replaced when its service life has expired.

Abstract: A vent assembly for use with a respiratory mask of the type used in CPAP treatment includes a porous disk portion that is attached to a biasing member such that the disk portion is maintained in a substantially sealed position against a main vent to minimize airflow through at least one side vent of the vent assembly. Debris build-up on the disk portion can cause the biasing member to deflect to provide an additional path for airflow through the at least one side vent. In another embodiment, the vent assembly can also include an anti-asphyxia feature to provide an airflow path from the environment to the user. An oxygen diverter valve may be disposed between the breathing apparatus flow generator and an oxygen injection port.
