Abstract: A seal and a mask having a seal adapted for confronting engagement with a surface of a user to form an interface therewith. The seal includes a first portion defined by a gel substance and a second portion associated with the first portion. The second portion includes a selectively formable substance adapted to be molded from a first pattern into a second pattern and to retain the second pattern responsive to being so molded. The seal and mask having the seal is tailored to patient by causing the formable portion of the seal to be placed in a malleable state, applying the seal to the patient while the formable portion is in the malleable state, and causing the formable portion to be placed in a fixed state to retain a shape generally conforming to the portion of the patient underlying the seal.

Abstract: A mask is provided for administering medication, particularly asthmatic medication, to equine animals, particularly horses. The mask has a body that fits over the nostrils of the horse. An aerosolization chamber is secured to the body and opens into the interior thereof, and is supplied with misted medications such as from a metered dose inhaler, for inhalation by the animal. The mask and body is also provided with one or more exhalation ports, and a strap or band or the like for securing the body to the animals face overlying the nostrils.

Abstract: A nasal mask assembly that includes a seal member defined from a unitary piece of elastomeric material. The seal member defines a nose receiving cavity and has a first end portion and a second end portion generally opposite the first end portion. A first opening in the first end portion allows at least a portion of a nose to enter the nose receiving cavity such that the nares of the patient communicate with the nose receiving cavity. The seal member includes a neck portion defined in the second end portion and a second opening defined in the neck portion in communication with the nose receiving cavity. A reinforcement area is provided on the side walls of the seal member. The reinforcement area comprises a saddle shaped contoured area on each side of the seal member. Each saddle shaped area has an upper and a lower protrusion portion for providing supporting contact with the face.

Abstract: An air-impermeable hood having first and second substantially airtight seals adapted to encircle a portion of a wearer's body below the head, typically the neck. Continuously exhaled air from the wearer of the hood is channeled between the first and second seals pressurizing a space there between creating a continuously pressurized purge zone to the introduction of ambient air into the hood. When the pressure in the purge zone exceeds the resistance of the second seal, air taking the path of least resistance flows out of the second seal. The effect is that exhaled air from the wearer creates a pressurized barrier against ambient air yet also prevents the accumulation of excess carbon dioxide and moisture within the ocular area.

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.

Abstract: This invention relates to a connecting part of a breathing mask for connecting components such as filter, speech diaphragm, or exhalation valve that is inserted directly into the eye-protecting lens and guarantees easy assembly and disassembly.

Abstract: A surgical mask adapted to cover the nose, mouth and eyes of the wearer is disclosed. A transparent lens component is positioned to cover the eyes of the user. A light-transmitting filter element being hingably connected to the upper edge of the transparent lens. The filter may be positioned selectively into overlapping relation of the lens to provide a filtering function or folded 180° to remove the filter from overlapping relation of the lens panel. The filter and lens panel are connected such that a degree of relative lateral movement between the components is provided whereby the filter may be moved between overlapping and non-overlapping conditions of the lens without removing the mask from the wearer.
